Subject: [PATCH 001/167] Edit CSV tables directly and remember column widths
 (#25442)

* Add direct CSV table editing and persistent column widths

* Preserve pending CSV edits across concurrent saves and panes

* Keep CSV input stable during autosave and table commands

* Cancel delayed menu paste after CSV pane focus changes

* Prove delayed CSV menu paste starts before focus changes

Subject: [PATCH 002/167] test(linear): cover numeric-leading issue identifiers
 (#10241)

Expand numeric-leading Linear identifier coverage in the current parser and workspace source flow while rejecting numeric-only team keys in bare inputs and URLs. Main already implements the production behavior through #23423.

Repair two stale localization test assumptions found by full CI. All changes are regression tests.

Validation: 369 focused tests across 46 suites, local typechecking/lint/formatting, and full final-head CI passed.

Subject: [PATCH 005/167] fix(mobile): stop Android from selecting words while
 the chat transcript scrolls (#22871)

* fix(mobile): stop Android from selecting words while the chat transcript scrolls

On Android every paragraph, heading, quote, code block and table cell in
the native chat transcript was a selectable TextView. Android starts a
word selection, with the magnifier, on a double tap or a long press, and
two flicks in the same spot while scrolling a FlatList register as a
double tap, so scrolling the chat kept selecting words. iOS is unaffected:
its UITextView path arbitrates scroll against selection itself.

Android now renders transcript text without inline selection: one gate in
MarkdownText covers every selectable span, and the user bubble follows
it. A long press on a message opens a sheet with "Copy message" and
"Select text", the latter a screen whose only content is one selectable
Text, so a selection can only start where the user asked for it. The
message row owns that sheet and mounts it only while open. iOS and web
keep their inline selection and get no long-press handler.

Verified on a Pixel 10 Pro Fold (Android 17): an adb double tap on the
transcript selects nothing, the same double tap inside "Select text"
selects a word, tool rows inside the bubble still expand on tap, and the
long press opens the sheet.

* fix(mobile): scope the Android selection gate to the transcript and route span long presses

Review follow-ups on #22871:

- The gate now applies only where `rangeSelectable` is passed (the chat
  transcript). Task comments and file previews keep their selectable text
  on Android as before.
- On the Android transcript, spans that take taps (links, file paths)
  also take the row's long press, so a link under the finger no longer
  swallows the copy/select sheet.
- Copied text keeps its whitespace; only whitespace-only blocks are dropped.
- The Android markdown test compares `String(node.type)` instead of a
  type assertion, which the changed-code quality gate rejects.

* fix(mobile): route long presses on Markdown images to the row on Android

An image block is a Pressable of its own, so on the Android transcript it
now carries the row's onLongPress like tappable spans do; a long press on
an image opens the copy/select sheet instead of being swallowed. Test
extended with an image block.

* test(mobile): pin the Android long press from a chat row to its actions sheet

The existing row suite runs as iOS, where the bubble has no long press.
This one runs as Android: the bubble's long press mounts the actions
sheet with the message, the markdown receives the same handler, closing
unmounts the sheet, and the user bubble carries no inline selection.

* fix(mobile): preserve Android message selection while replies stream

-# E2E Test Plan: SSH config host picker (`import-ssh-config-does-nothing`)
-
-## Branch summary
-
-Users can open **Fill from ~/.ssh/config…** on the add-SSH-host dialog, pick a
-Host alias, and get the form prefilled from `ssh -G` resolution. Bulk sync is a
-secondary **Add all N to Orca** action (no re-adopt). Settings → SSH → **Import**
-remains the deliberate re-adopt path.
-
-Commits under test (vs main):
-
-- `bd0b594dee` feat(ssh): add SSH config host picker for add-host form
-- `dc8339369a` fix(ssh): import filter preservation and label fallback
-- `5982c8108f` fix(ssh): harden config picker import, alias folding, host targeting
-- `5cfb6369e7` refactor(ssh): centralize host result limit / folder group helper

-E2E is reserved for real Electron HOME isolation, real `~/.ssh/config` parse,
-real `ssh -G` resolve, and user-visible DOM outcomes.
-
-## Harness requirements
-
-1. **Isolated HOME** — E2E already sets `HOME` to `{userDataDir}/home`. Seed config with:
-   ```ts
-   const home = await electronApp.evaluate(({ app }) => app.getPath('home'))
-   mkdirSync(path.join(home, '.ssh'), { recursive: true, mode: 0o700 })
-   writeFileSync(path.join(home, '.ssh/config'), configBody, { mode: 0o600 })
-   ```
-2. **Unique aliases** — prefix Host entries and Orca labels with
-   `e2e-ssh-cfg-${Date.now().toString(36)}-…` so workers never collide; clean up
-   via `window.api.ssh.removeTarget` in `afterEach` by label/configHost prefix.
-3. **Open the picker dialog** (not Settings `SshTargetForm` — that form has no
-   config picker). Path:
-   - Open **Add Project** (sidebar / landing control)
-   - Host combobox → **Add remote host** → **Add SSH host**
-   - Dialog title **Add SSH host** with link **Fill from ~/.ssh/config…**
-4. **Assertions** — DOM only (`getByRole`, `toHaveValue`, visible badges/toasts).
-   Store/API only for setup/cleanup/seeding existing targets.
-5. **Prereq** — OpenSSH client on PATH (`ssh -G`). macOS/Linux CI has it; skip
-   or soft-fail only if `ssh -G` is unavailable (document in test comment).
-
-## Spec file
-
-`tests/e2e/ssh-config-host-picker.spec.ts`  
-Reuse patterns from `ssh-host-form-modal.spec.ts` (session ready, target cleanup,
-announcement dismiss). Prefer small local helpers over new shared modules unless
-helpers would be reused elsewhere.
-
-Optional second file if the Settings Import case grows:  
-`tests/e2e/ssh-config-import-settings.spec.ts` — otherwise keep Import in the same file.

-| ---------- | --------------------------------------------------------------------------------------------------------------------------------------- |
-| **Setup**  | Do not create `~/.ssh/config` (or write empty file).                                                                                    |
-| **Steps**  | Open Add SSH host → Fill from ~/.ssh/config…                                                                                            |
-| **Expect** | Dialog title **Choose from ~/.ssh/config**; body **No hosts in ~/.ssh/config**; **Add all to Orca** disabled; **Back** returns to form. |
-
-### P2 — Seeded hosts listed with summary lines
-
-|            |                                                                                                                       |
-| ---------- | --------------------------------------------------------------------------------------------------------------------- |
-| **Setup**  | Write config with ≥2 concrete Hosts, e.g. `e2e-alpha` / `e2e-bravo` with HostName, User, Port.                        |
-| **Steps**  | Open picker.                                                                                                          |
-| **Expect** | Host list `SSH config hosts` shows both aliases; subtitle `user@hostname:port`; button **Add all 2 to Orca** enabled. |
-
-### P3 — Select host prefills form (and Save persists)
-
-|            |                                                                                                                                                                                                                                                                                                          |
-| ---------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |

-| **Steps**  | Pick `e2e-prod` → wait for form → click **Save**.                                                                                                                                                                                                                                                        |
-| **Expect** | After pick: Host/alias field = `prod.example.test`, Username `deploy`, Port `2222`, Label `e2e-prod` (or alias); optional toast _Filled from e2e-prod_; Identity file may stay empty with config hint. After Save: dialog closes; target appears in Settings → SSH (or listTargets shows matching host). |

-| **Expect** | Deleted config host reappears as an Orca target; toast sync count ≥ 1. |

-
-## Nice-to-have (only if cheap after P1–P9)
-
-- **N1** ProxyCommand / JumpHost: pick host with ProxyJump → Advanced opens and jump field filled (proves advanced prefill + `preferAdvancedOpen`).
-- **N2** Case-insensitive alias: config `Prod`, existing label `prod` → **In Orca**.
-- **N3** Empty Identity file hint visible after config fill.
-
-Skip: 100-host truncation, resolve races, GSSAPI system-default, composer host-availability fail-closed (unit-covered).
-
-## Out of scope
-
-- Real SSH connect / relay / PTY
-- Docker SSH fixtures
-- Web client stub paths (`listConfigHosts` returns empty)
-- i18n non-English

-Shared helpers: `tests/e2e/helpers/ssh-config-host-picker.ts`
-
-### Product fix required for E2E (and real HOME isolation)
-
-OpenSSH resolves the default user config via **getpwuid**, not `$HOME`. E2E
-sets an isolated `HOME`, so `loadUserSshConfig` (Node `os.homedir()`) and
-`ssh -G` could disagree. `src/main/ssh/ssh-g-config-resolution.ts` now passes
-`-F <homedir>/.ssh/config` when the HOME config path exists and differs from the
-passwd home. Normal installs (HOME = passwd home) are unchanged.
-
-## Suggested run command
-
-```bash
-pnpm exec electron-vite build --mode e2e
-SKIP_BUILD=1 pnpm exec playwright test \
-  tests/e2e/ssh-config-host-picker.spec.ts \
-  tests/e2e/ssh-config-host-import.spec.ts \
-  --config tests/playwright.config.ts --project=electron-headless --workers=1
-```

Subject: [PATCH 007/167] fix(codex): resume account switches without blanking
 the terminal (#25485)

fix(codex): restart account switches without blanking or repinning the pane

Integrate the atomic pane replacement from #24350 and adapt the explicit
conversation resume from #14877. Keep terminal protocol replies flowing
while account notices block user input. Ordinary restores retain provenance.

Subject: [PATCH 008/167] Submit initial OpenCode 2.0.12 prompts through the
 native startup plugin (#25428)

* fix(opencode): submit initial prompts for reviewed 2.0.12

Route the reported release through the existing native startup intent.
Retain conservative behavior for other unreviewed versions.

* Wait for OpenCode startup fixture file reads in the hydration test

* feat(jira): pick the assignee when creating an issue — Automatic, me, or anyone

The new-issue dialog gains an Assignee picker: Automatic (Jira applies the
project's default assignee), one-click "Assign to me" resolved from the
target site's stored identity, or any user via search. The selection resets
with the custom field values on project/type switches, since account ids
are site-scoped.

Creates now also send userFieldKeys, so the host shapes user-typed values
into the {accountId}/{name} refs Jira requires — previously the dialog
never passed them and user create fields were sent as bare strings. Keys
are only named when a value is present, keeping older remote hosts without
the user-fields capability working for assignee-less creates.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* fix(jira): address assignee review — project-scoped assignable search, per-site picker remount, keep assignee across type changes

- Search the create dialog's assignee picker against /user/assignable/search?project=…
  (new listAssignableUsersForProject, IPC split into jira-user-search.ts for the
  max-lines budget); remote environment targets fall back to the existing
  site-wide search since older hosts have no such RPC
- Remount the picker per target project so cached results from the previous
  project or site cannot be selected after a switch
- Reset the picked assignee on project selection (account ids are site-scoped)
  instead of on every create-fields reload, so issue-type changes keep it
- Hide the assignee field and omit it from the payload when the target create
  screen does not accept an assignee — Jira rejects fields absent from the screen

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* fix(jira): scope create assignee to the effective project and provider

* fix(jira): isolate assignee search candidates across provider changes

* fix(jira): search assignable users with Server-compatible project keys

* fix(jira): refresh assignee identity with provider connection status

* fix: distinguish hook confirmation from browser confirm

@@ -2519,3 +2519,67 @@ catalog subjects and declared qualification inputs survive the rebase unchanged.
 These are fresh-process wall times for this cohort, excluding dependency setup,
 queues and other test shards. They do not measure full-shard balance, total PR
 runner demand, or a change to the dashboard's PR runtime percentiles.
+
+## October 5 fused terminal cursor row scans
+
+Readiness checks repeatedly read terminal rows to recognize composer text.
+The shared reader now collects undimmed text and the first visible glyph's style
+in one pass. The cursor suffix remains a separate scan; dim glyph attributes,
+empty cells, wide characters and wrapped spaces keep their existing behavior.
+No grid data is retained between calls.
+
+The [hosted comparison](https://github.com/stablyai/orca/actions/runs/37263358478)
+used source `1bec53ceb23b5f296a38ffa0e085778d32fc7849`, Linux ARM,
+Node 24.21.0, pnpm 12.8.1 and one worker. All six fresh processes ran the same
+49-case readiness census module, with separate empty Vite caches, filesystem
+transform caching disabled and Node compile caching disabled.
+
+| Complete focused process | Original | Candidate | Paired saving |
+| ------------------------ | -------- | --------- | ------------- |
+| Pair 1                   | 66.412s  | 60.464s   | 5.948s        |
+| Pair 2, reversed order   | 66.880s  | 61.061s   | 5.819s        |
+| Pair 3                   | 68.056s  | 65.821s   | 2.234s        |
+
+The median paired saving is 5.819 seconds, or 8.7% of this fixed workload.
+All 294 timed case outcomes passed. Separate qualification preserves complete
+context/composer outputs on 98 recordings and the logical cursor/projection
+outputs of all 192 Runtime census cases. Nine actual scanner faults fail the
+intended assertions; the 89-case IME/composer slice also passes. Blank-row tests
+bound cell reads to 72 instead of the original 132 for a 12-column, five-row grid,
+with and without a reusable cell adapter.
+
+The raw timer-driven polling trace differed and was excluded from equivalence
+evidence. Logical per-frame output captures match; no raw polling-count equality
+is claimed. These measurements exclude setup, queues and other modules and do
+not establish a change in full-shard balance, PR percentiles or runner demand.
+
+## October 5 Qoder test import guards
+
+The direct Qoder Runtime tests now import the existing unused-default-RPC guard
+before their Runtime fixture. Their complete test bodies remain unchanged.
+The guard rejects an unexpected registry access instead of loading the full
+default-method graph. The three real registry catalogs remain unmocked.
+
+The [hosted comparison](https://github.com/stablyai/orca/actions/runs/37266875139)
+used fixed source `1bec53ceb23b5f296a38ffa0e085778d32fc7849`, Linux ARM,
+Node 24.21.0, pnpm 12.8.1 and four isolated fork workers. Every fresh process ran
+both Qoder files and all three catalogs: 85 cases across five files. Each invocation
+used a distinct empty Vite cache, with results, filesystem transform and Node
+compile caching disabled. All 510 timed outcomes passed.
+
+| Complete five-file process | Original | Candidate | Paired saving |
+| -------------------------- | -------- | --------- | ------------- |
+| Pair 1                     | 17.677s  | 16.323s   | 1.354s        |
+| Pair 2, reversed order     | 16.827s  | 16.021s   | 0.806s        |
+| Pair 3                     | 17.324s  | 16.211s   | 1.113s        |
+
+The median paired saving is 1.113 seconds, or 6.4% of this fixed workload.
+Separate actual faults in retained launch recipes, Qoder command selection and
+method registration fail the same intended assertions before and after the
+imports. Generated launch IDs and shifted stack lines differ in the raw failure
+messages; they were preserved and are not claimed byte-identical.
+
+The single hosted trial occupied 134 runner-seconds including all six samples,
+shared setup and upload. That is trial cost, not a production saving. These
+focused process measurements do not establish full-shard savings, PR runtime
+percentiles, queue relief or a change in the organization's runner allowance.

Subject: [PATCH 011/167] fix: prevent IME confirmation from submitting text
 fields (#25480)

Keep IME confirmation out of text-field submission and command selection. Reuse shared gesture ownership, preserve marked-release redispatch, guard overlay Escape capture, and retain Markdown save shortcuts.

Verified with independent adversarial reviews, 891 tests across 71 files, six hidden Electron tests, project typecheck, full lint, the changed-code quality gate, and all final-head CI checks.

Fixes #25035.

@@ -100,3 +100,47 @@ Each fix must pass all of these checks:
   regenerate its bundle patch and lockfile together.
 - Prefer deterministic replay or state-transition tests. Native evidence is a
   second layer, never a substitute for regression coverage.
+
+## Enter in application text fields (#25035)
+
+Use `Input`, `Textarea`, or `CommandInput` for styled fields. Existing unstyled
+fields with keyboard actions use `ImeInput` / `ImeTextarea` from
+`lib/ime-text-field.tsx`; those preserve the DOM element, styles, refs, and
+composition callbacks. They share `useImeEnterGestureOwnership` and keep
+IME-owned keys out of both field actions and bubbling form/menu shortcuts.
+Overlay primitives also reject IME-marked Escape in document capture, where
+field-level propagation guards cannot intercept dismissal.
+Do not add a second tracker at a call site already using a guarded field.
+Native Chat and the File Explorer inline name field retain their existing
+trackers because they also own specialized composition or element lifetimes.
+
+Required cases:
+
+- `isComposing`, `keyCode: 229` without `isComposing`, and `Process/229` must
+  never submit, choose a suggestion, or dismiss the field.
+- The unmarked Enter redispatch stays owned on either side of keyup, including
+  a `Process/229` release. A
+  subsequent ordinary typing/navigation key ends that carry immediately;
+  hidden renderers may defer animation frames, and typing a filename suffix
+  must not cause the next deliberate Enter to disappear.
+- Composition callbacks, blur, refs, and keyed remount cleanup still work.
+  Normal Enter, modifier submits, and Shift+Enter newlines remain available.
+- Test the actual shared field when a consumer delegates IME handling to it;
+  a mock that replaces `CommandInput` with a raw input removes the protection.
+
+`ime-text-field.test.tsx` covers primitives, raw fields, parent handlers, and
+command selection. File Explorer component tests cover all three operations
+and input replacement. `file-explorer-ime-enter.spec.ts` drives Chromium
+composition in New File, New Folder, and Rename in a folder workspace, then
+checks the complete name in the Explorer and on disk, with both continued typing
+and a redispatch followed by deliberate Enter. Overlay tests cover IME Escape
+and ordinary dismissal; Markdown tests preserve an unmarked save shortcut while
+composition state lingers. These are CDP event
+contracts, not native OS keyboard evidence.
+
+The audit also covers settings and title fields, issue/review creation and
+pickers, comments and annotations, search fields, Native Chat questions,
+notebook execution shortcuts, and Markdown menu handlers. Terminal input keeps
+its existing xterm/PTY ownership; mobile native fields use `onSubmitEditing`
+instead of desktop DOM keydown actions. Remote workspaces use the same renderer
+fields; file-operation routing and mixed-version wire contracts are unchanged.

Subject: [PATCH 013/167] refactor(terminal): one commit module for terminal
 topology closes, with a boundary check (#25329)

* refactor(terminal): move the topology revision and leaf-lookup helpers into terminal-topology

advanceTerminalTopologyRevision, findTerminalTabIdForLeaf and
hasHostAuthoritativeTerminalMembership move verbatim from the renderer-save
membership rebase into persistence/terminal-topology, the home of the commit
boundary. Importers are repointed; no behavior change.

* test(terminal): test-only guard for topology writes outside the commit boundary

The three session sinks now publish through one commitWorkspaceSessionPartition
helper, which hands the prior and published partition to the topology write
guard. Production never arms the guard, so each sink pays one global lookup.

The unit suite arms it in report mode: a sink write that changes class-(a)
topology (membership, root, bindings, titles, incarnations, sleeping records,
remote session ids, tombstones, default-applied, revision) outside a commit
scope is attributed to its writer's file by stack, and fails the test unless
the writer is on the unrouted-writers allowlist that later routing PRs shrink.
Renderer saves and test seeding are exempt. Deep-freeze is available but stays
off suite-wide until the in-place writers return new sessions.

* refactor(terminal): add the topology commit module with bindLeaf, closeLeaf and closeTab

terminal-topology-commit.ts is the boundary for class-(a) terminal topology.
bindLeaf forwards to persistPtyBinding, whose write now runs in a commit
scope; the spawn commits and the relay reattach bind through it. closeLeaf and
closeTab wrap the existing close mutation in a commit scope and one
persistence.terminal-topology span (kind, outcome, refusal reason; no ids),
and the runtime close goes through them. Session output is unchanged: tests
compare it byte for byte with the old writers for local, ssh: and folder
workspaces.

* chore(terminal): drop an unused lint suppression from the topology write guard

* fix(terminal): attribute topology guard writers relative to the repo root

The guard read a frame's file through its last /src/ segment, so a test under
tests/ (folder-upgrade-identity-persistence.unit.test.ts) had no source frame
and failed as an unknown writer. Frames are now taken relative to the repo
root the setup passes in, tests/ counts as test seeding, Windows backslashes
are normalized before the node_modules skip, and nested src/ paths keep their
full path. The two runtime funnel files skip only their funnel function, so
another writer in them still shows. The R9 allowlist key names the file whose
frame actually writes. The class-(a) diff and the attribution move into their
own files; the stack limit is restored in a finally.

* refactor(terminal): drop bindLeaf until binding reaches a sink; add the boundary ratchet

bindLeaf and the commit scope inside persistPtyBinding changed nothing: the
binding write never reaches a session sink, and a scope inside the Store method
would have admitted every direct caller once it did. Both return in B1-4; the
spawn commits and the relay reattach call persistPtyBinding directly again.

The runtime close now calls one closeLeafOrTab entry, so its callbacks keep
their contextual types. A census test is the primary enforcement: only
persistence/terminal-topology and the callers it lists may call
persistPtyBinding, the session setters or the three sinks, and every
unrouted-writer allowlist entry must name an existing file.

* fix(test): resolve the topology guard's repo root without the global URL

Under happy-dom the global URL is not Node's, so fileURLToPath(new URL(...))
threw in the setup file and failed every happy-dom test file.

* refactor(terminal): drop the runtime topology write guard; the boundary ratchet enforces

The AST boundary ratchet is the enforcement for B1. The stack-attributed
runtime guard, its class-(a) diff, the unrouted-writer allowlist, the vitest
setup and the freeze option are removed; it saw two writers in the whole unit
suite and its real value starts only once binding reaches a sink (B1-4).

Also: one closeLeafOrTab wraps the close in the span (no per-kind copies or
narrowed types), the span has one finish like persistence.pty-binding, the
sink helper is publishWorkspaceSessionPartition (it publishes; the commit
boundary is the module), the ratchet drops the private publishSession row and
checks that every listed caller file exists, and the close comparison keeps
its two meaningful cases with span cases chosen by name.

* refactor(terminal): trim the B1-1 commit module and ratchet to what they enforce

- Point the acknowledged-tab-retirement audit fixture at the moved
  advanceTerminalTopologyRevision; its old import no longer resolved.
- Drop publishWorkspaceSessionPartition: it was the removed guard's
  interception point, so the three session sinks return to origin/main.
- One traced(kind, mutate) wrapper in the commit file replaces the span
  factory; closeLeafOrTab is one call.
- The ratchet walks src/main with the shared scanSourceTree, drops the
  loading-store-internal rows and the redundant file-exists test; exact-set
  equality already fails on a missing file.
- The commit test is a pure unit test of the span outcomes: no Store
  harness, electron mock or self-comparing close.

* refactor(terminal): census the runtime session controller's write and drop stage ids from comments

The controller's setter was named set, which the boundary census could not
list without matching every Map.set, so a new OrcaRuntime mixin could write
sessions through it unseen. Rename it setForWorktree and census it.
Comments now describe state instead of citing plan stage ids.

* refactor(terminal): census writer references and trace refusals by callback

- traced() takes refusalOf instead of assuming an Error refusal, and only
  mutate() sits in the try, so a span outcome of threw means the write threw.
- The boundary ratchet counts references, not just direct calls: non-null
  calls, bracket keys, aliases, destructures, .call/.bind and parenthesized
  callees all count; declared names and type positions do not.
- Census terminalSurfaceCloseMutation (boundary-only) and the partition sinks
  setLocalWorkspaceSession / setHostWorkspaceSession.

* test(terminal): count writer uses in extends clauses and instantiations, skip type-only imports and local declarations

The census skipped ExpressionWithTypeArguments as a type, which also holds
`extends f(x)` and `x<T>` value expressions. Type-only import/export
specifiers and declared names (variables, parameters, accessors, enum
members) no longer count as uses. The audit fixture is listed in the table
instead of a separate exemption.

* test(terminal): count quoted and assignment-pattern destructures of layout writers

* test(terminal): count every mention of a layout writer except its definition

Telling definitions from uses per syntax kind kept missing nested and
for-of destructures. Exempt only the writer's own function or class-member
definition; any other mention (including object-literal keys) counts, so the
census errs toward a loud false alarm rather than a silent miss. Quoted names
count only in member-name position.

* test(terminal): count every string literal naming a layout writer

Member-name positions missed wrapped keys like store[('name')] and
store['name' as const]. Counting every string literal outside types is
shorter and errs toward a loud false alarm.

* test(terminal): exempt only class members and functions as writer definitions

Object-literal methods and accessors were exempt while equivalent arrow
properties counted; all object-literal keys now count alike.

* test(terminal): parse files with unicode escapes in the writer census

A name spelled with a \u escape never appears verbatim, so the text
prefilter skipped it.

* test(terminal): parse any file with an escape in the writer census

\x, identity and line-continuation escapes also decode to a writer name
without it appearing verbatim.

Subject: [PATCH 014/167] fix(native-chat): a Stop binds only the turn it
 actually stopped (#24864)

* fix(native-chat): a Stop binds only the turn it actually stopped

A Stop pressed before any turn showed used to claim, at end-write time,
whatever turn the stopped send later opened, even when the Stop stopped
nothing. A turn that then died on its own read as "Interrupted" (your
cancellation) instead of "Failed".

Now a person's Stop that named no turn binds, in memory only, every turn
that ends while the Stop settles, and afterwards only the turn its
interrupt took. The settle ends a still-running stopped turn once. A
relaunch finds nothing in memory, so an unsettled turnless Stop binds no
turn. A Codex Stop whose answered turn does not open within its wait, or
whose send's answer was lost, now answers refused, so the host ends the
child and the turn can never run.

* fix(native-chat): keep the person's queue pause and close binding after a Stop settles

A host stop or eviction with no turn running now defers to a person's
Stop while its queue pause still holds with nothing sent since, read from
rows, so a held card is not handed off on reopen after a Stop that did
nothing or whose kill failed.

A person's close that named no turn opens a settle around its child's
end, so a turn that end cuts reads as theirs.

A press opens its settle only when the latest Stop event is its own or
the one in force it repeats: a late Stop, a card's interrupt or a lost
event row reopens no earlier Stop.

A Codex Stop that cannot reach a turn still able to open says the Stop is
unconfirmed rather than that no turn ran, and a second Stop still reaches
a turn an earlier wait left unopened.

Also drops the unused openedBy plumbing and the unreachable "a written
cancellation stays one" rule, and pins a relaunch after a named Stop.

* fix(native-chat): a Codex Stop agrees on both presses when a turn is still owed, and pin the close's settle

A Codex Stop that waited for a turn Codex answered a send into now answers
"may still open" whenever that turn neither opened nor ended and its send
is still owed, however the wait ended (it ran out, or the thread went
idle). Before, a first press after an idle thread said no turn was
running and kept Codex, while an identical second press ended it.

Adds a test that a person's close the conversation outlives (as /clear
does) closes its settle, so a later turn that ends on its own reads as a
failure.

* test(native-chat): a Stop whose event row failed binds no turn to an earlier Stop

With one ordered journal writer the Stop's event is in the fold when its
write returns, so the press reads whether it owns the latest Stop from the
fold instead of awaiting the write. Pins the case the read must refuse.

* test(native-chat): name the settle, not a stream drain, in the Stop's own-end test

* test(native-chat): a Codex Stop answered before Codex ends the turn reads interrupted throughout

Codex answers an interrupt it took before it sends turn/completed (interrupted):
on TurnAborted the app-server answers pending interrupts, then ends the turn, on
one channel. The test fake did the reverse. It now answers first and ends the
turn on a later read, and the tests that read the turn's end right after a Stop
wait for it.

New end-to-end test through the shipped host, journal and Codex adapter: with
the real order, every end row of the stopped turn reads interrupted by the Stop
(named, unnamed, and a Stop pressed while turn/start was in flight). Breaking the
settle window turns the in-flight case red: the Stop's own end row then has no
verdict, which reads as failed until Codex's end lands.

* fix(native-chat): a Codex Stop interrupts a turn Codex answered but has not opened at once

A Stop that named no turn, made after Codex answered a send but before the turn
opened, used to wait up to 5 s for the turn to open before interrupting, and
ended the Codex process when it didn't. The stated reason, that Codex refuses an
interrupt until it opens the turn, holds only part of the time: with no turn
active, Codex takes an interrupt once its thread runs (turn_interrupt_inner),
and refuses it with -32600 "no active turn to interrupt" before that or once
the turn has ended.

The Stop now sends the interrupt at once. Only on that refusal, while the turn
has neither opened nor ended, does it wait for the turn to open (bounded at
5 s) and send it once more. A turn that ended meanwhile was nothing to stop. One
that never opens, or that an earlier wait already gave up on, fails the Stop,
and the host ends the child as before. Sends still wait for the turn to open
before steering into it.

The test fake models Codex taking an interrupt once the thread runs (run()).

* fix(native-chat): every Codex Stop waits for an answered turn to start, as the first did

A Stop whose interrupt Codex refused as finding no active turn skipped the wait
when an earlier wait, a Stop's or a send's, had already given up on that turn.
Every press now waits its own bound and retries once if the turn starts, so a
turn that opens during a later press is still stopped. Both presses still reach
the same verdict when it never starts.

* fix(native-chat): a Codex Stop that ends the child before any turn opened withdraws its send

A Stop on a Codex turn that was answered but never opened ends the Codex
process. That end settled the send as in doubt (unknown, recovered), and the
client's outbox holds every later send behind a send in doubt until the person
presses Retry, which re-sends the very message they stopped. The chat looked
stuck.

Codex records a prompt only once its turn has started, so a send whose turn
never opened never ran. When the Stop's refusal says so (turnMayOpen), the child
end now settles the unanswered sends as withdrawn, the verdict Codex's own
interrupted-turn end already gives an unechoed send. The flag rides on the owed
wind-down, so a retry after a failed child end withdraws them too. Claude's
child end still leaves its unanswered send in doubt.

* fix(native-chat): derive the withdrawal of a Codex send whose turn never opened

Replaces the flag the Stop carried to the child's end, and its copy on the owed
wind-down, with a reading of the journal at the settlement that lands. A Codex
child's unanswered send is withdrawn when a person's Stop is in force since it
was sent and no turn row ran, or was written, after it; any other end (a turn
that opened, a host's close, a crash, Claude) still leaves it in doubt. A
retried wind-down reads the same rows, so it withdraws the same sends.

* fix(native-chat): keep a send in doubt when a turn was open for it

The derived withdrawal read a turn as open for a send only if it still ran or
was written after the send. A send steered into a running Codex turn whose
interrupt failed met neither once the adapter's end settled that turn ahead of
the host's settle, so it read withdrawn, though Codex drains a steer into the
running turn and may hold it. A turn that ended after the send was handed over
was open for it too: such a send stays in doubt, as before.

Pins that case, and that a send made after the Stop, to a child that then dies
before its turn opens, stays in doubt.

* fix(native-chat): withdraw a Codex send by whether it started its own turn, not by timing

Whether a turn was open for a send was read from end times: a turn that ended
after the send's handover counted. A send made while a Stop ended the turn is
handed over once that turn reads ended, yet Codex's own end for it can arrive
later, so such a send whose own turn never opened read in doubt again, and the
chat's queue held behind it.

The handover already records where the send went: its message joins the turn
running then (a steer) or belongs to no turn (it starts its own). Only a send
that started its own turn, with none opened since, is withdrawn; one that
joined a running turn, or has no recorded place, stays in doubt.

The Codex test fake takes an answered interrupt as Codex does, dropping the
turn before its end arrives.

* fix(native-chat): leave no Stop row when the Stop took back a send that never ran

A Stop on a Codex send whose turn never opened ends the child, and the child's end
takes the send back into the composer. The Stop still wrote "Cancellation
requested." at the conversation level, so with the send gone it sat under the
previous finished turn and read as if that turn had been stopped. A Stop that found
no turn running and whose child end took back every send it found now writes no
row; a Stop of a running turn, or one that leaves a send in doubt, still does.

* fix(native-chat): count a send whose answer was lost when a Stop takes it back

The no-row rule counted only pending sends, but the child's end also takes back a send this process left in doubt when Codex's turn/start answer was lost. That case still wrote "Cancellation requested." under the previous turn. Both now read one predicate, so they cannot drift apart.

* test(native-chat): pin which sends a Stop's child end can take back

A send an earlier process left in doubt is never withdrawn and never holds the row back, and a queued card's send is never counted.

* test(native-chat): read the outbox reconcile from where main moved it

Subject: [PATCH 015/167] fix(native-chat): a chat's finished-turn alerts come
 from the host recorded on its tab, not its workspace id (#25081)

* test(native-chat): a mirrored paired chat carries its host, so a workspace-id collision no longer hides its owner

* fix(native-chat): a chat's finished-turn alerts come from the host stamped on its tab, not its workspace id

* fix(native-chat): the attention bridge reads a chat's owner from the same rule as the chat pane

Subject: [PATCH 016/167] fix(native-chat): never delete chat history on read;
 a chat Orca can't load says why once (#24576)

* fix(native-chat): an older Orca keeps a chat with newer content read-only, and an unreadable annotation costs only itself

A body or lifecycle mutation of a kind this build does not know, inside a row of a known kind,
now latches the chat read-only with every row kept, as a newer row kind or version already does.
It used to read as damage, and the open deleted the journal from that row on.

Each optional field of a body schema now declares what an unparseable value means:
- droppable (an annotation): removed from the row in memory; the chat stays writable;
- must-understand (a prompt's questions, a plan approval's plan, a turn's lifecycle, a goal
  change): the row is unreadable and the chat latches read-only.
Only a required field that fails is damage, repaired as before. A test holds every optional
field reachable from a body schema to a policy; the known body kinds are read off the schema.

Prompt options and questions no longer reject a key this build does not know, which deleted the
journal from that row on. The context-usage drop is now one case of the droppable rule.

* feat(native-chat): a chat an older Orca keeps read-only says so before a send is refused

A chat a newer Orca wrote opens read-only, and until now nothing said so: the person found out
when a send failed with "Chats were saved by a newer Orca". The host now names the reason on
every whole history page it serves (`page.readOnly: 'written-by-newer-orca'`: hydration, history
and catch-up resets), the shared client reducer keeps it from the latest whole page, and the
desktop status strip and the phone's composer area say "This chat was saved by a newer Orca, so
it's read-only here. Update Orca to continue this chat."

Every read-only latch the host has is a newer Orca's (its database, a row version, a row kind, a
body kind or must-understand fact), so the reason is derived from the journal's latch, not stored.
The field is optional: older clients ignore it (cross-version test against the newest release's
reducer), and older hosts never send it, so a new client against one says nothing, as today. A
reason this client does not know shows nothing rather than words that may be wrong.

The window-merge helpers move out of the client reducer into their own module.

* fix(native-chat): only a newer build's value goes read-only; damage repairs as before

An older Orca keeps a chat read-only only on evidence a newer build wrote it: a value outside a
closed set this build knows (a body kind, a nested discriminant or literal, a mutation kind), read
off zod's issues. That evidence wins over damage beside it. Anything else that fails (a wrong type,
a missing field, a bad optional value) is damage, repaired as before, so damage no longer freezes
a chat behind an "update Orca" it cannot fix. Drops the per-field droppable/must-understand
policy. A lifecycle mutation's kind is decided before its item id, so a newer kind without one is
kept. The context-usage drop is unchanged from main.

* fix(native-chat): a read-only chat locks its composer and says why there

Removes the separate read-only line (desktop status strip, phone notice component). The host's
`readOnly` on whole pages now feeds the existing composer lock instead: desktop disables the
composer with "Saved by a newer Orca. Update Orca to continue this chat." as its placeholder, and
the phone adds a 'read-only' input-lock reason with the same words. A read-only chat shows no
prompt card it would refuse; the draft stays in the composer. The phone's send-failure line is
back exactly as on main.

* fix(native-chat): a read-only chat pages back through its history

A read-only journal answered every history request with a reset, so a chat this PR now keeps
read-only more often could show only its newest page. Backward reads now serve the snapshot the
open folded, as the first page already does; a forward read of rows still resets.

* test(native-chat): an unknown key in a question entry is read and kept

* test(mobile): the read-only overlay test typechecks

* chore(native-chat): satisfy the changed-code gate in admission and the read-only overlay test

* fix(native-chat): a new value inside a known block or goal arm reads as a newer build's

The open fallback arm of the block and goal unions now aborts, so zod reports the known arm's own
failure instead of only the fallback's; a future closed set there reads unreadable, damage there
still repairs. The schema headers name the context-usage exception and say a new open-string
value must be safe for every older build (rewind keeps only known states; pages carry no row
version).

* fix(native-chat): a read-only chat reconnects for a whole page, so an updated host unlocks it

The client keeps `readOnly` until a whole page replaces it, but reconnected at its cursor and got
only batches, so a desktop attached to a host updated in place stayed locked with "Update Orca".
While it holds the latch it now subscribes without a cursor; the snapshot re-derives the state on
any host version. The phone already subscribes without one.

* fix(native-chat): every desktop write control follows the one read-only fact

The structured session's transport state derives one fact from the page's `readOnly`: the words
for why the host refuses writes. Every write control reads it. While it holds, the chat has no
turn and no work, as the host projects it, so the working row and Stop go away; a pending prompt
stays shown above the composer with its card disabled; queued cards' Send now, Delete and Edit,
the queue's Resume, the goal banner's actions, the model and option pickers, dictation and
background-task Stop are disabled or withheld. The composer placeholder stays the one place the
reason is said. `lockReason` now locks the composer by itself.

* fix(mobile): every phone write control follows the one read-only fact

The phone session derives one fact from the page's `readOnly`, the words for why the host refuses
writes, and every write control reads it: no turn or work while it holds, so no Stop; the pending
prompt stays shown with its card disabled; queued cards and Resume are inert; the model and option
pickers stay shut; the composer field is not editable, so its placeholder keeps saying why, and the
lock applies at once instead of after the transport lock's settle.

* test(native-chat): the newest release hydrates a read-only chat and scrolls back through it

* test(native-chat): a read-only chat reads idle even with a send its provider never answered

* test(native-chat): composer lock test without type assertions

* fix(native-chat): round-3 read-only fixes

- An old /model or option request no longer reopens its picker when a read-only chat unlocks: the
  menu is keyed by the request alone, and a lock only keeps it from mounting open.
- A disabled question card still steps through its questions; only answering is locked.
- A failed send's notice in a read-only chat says only that the message was not sent, with no
  Retry: the composer already says why, and no retry can land. Its wiring moves into
  useStructuredAgentSessionDeliveryNotices.
- The host's background-task stop flags stand; the client no longer overrides them.
- The view reads the read-only fact through one local flag.
- The schema header says what an older build's rewind does with each open string.

* test(native-chat): count picker mounts without an effect

* fix(native-chat): read-only keeps other failures' words and shuts open option menus

- In a read-only chat, only a send the newer-Orca refusal stopped is shortened to "Your message
  was not sent."; any other saved failure keeps its own words, and none offers a Retry.
- A model or option menu open when the lock lands has its items disabled, so it cannot send a
  change the host would refuse.

* test(native-chat): lock-lands picker test uses a typed surface

* fix(native-chat): a locked composer draws its reason

The editor's placeholder used the default that draws nothing while the editor is not editable, so
a read-only chat's composer was empty and its reason lived only in the aria-label. The placeholder
now draws while disabled, and its words are empty unless the composer is locked with a reason, so
every other disabled composer (a pending prompt, no terminal) looks as before.

* fix(native-chat): sync the locked-placeholder flag in an effect, not during render

* fix(native-chat): a read-only chat is not offered for resume or counted as failed to resume

After a relaunch, a chat whose journal this build keeps read-only (a newer Orca's) was listed in
"Resume interrupted chats?", failed with "Orca couldn't resume this chat. Open it to continue
manually.", and left a status-bar "N chats failed to resume" that never cleared, since nothing can
continue a chat this build cannot write. The resume set now skips such a chat after the checks
that end an offer (fork, moved on), so the offer is kept, not spent, and an updated Orca offers it
again; the failure ledger keeps an already-filed failure for it but does not show it. Both read
the chat's open journal, which listing and acting open first.

* fix(native-chat): a refused resume continuation keeps the refusal's reason

A send refused while continuing a chat after a restart was filed with its code alone, so a newer
Orca's refusal lost its `journalWrittenByNewerOrca` reason. The continuation now carries the whole
refusal, as a refusal from the agent's start already did, so the filed failure keeps it.

* fix(native-chat): a newer Orca's chat keeps its resume offer however it is met

- A newer Orca's whole database counts as read-only for resume, so a chat whose journal cannot
  be opened at all (a table the newer schema changed) is not offered, run or counted either.
- The checks made right before sending no longer skip read-only chats: turning one away there was
  read as the user having moved on and deleted the offer. Its send is refused instead.
- Settling a resume files nothing for a newer Orca's refusal; the existing rollback reopens the
  offer for an updated Orca.
- The continuation records the refusal as a reference, without the wire prose.

* chore(native-chat): one import of the session wire types in the continuation

* docs(native-chat): resume and read-only comments match the current rule

* test(native-chat): a closed set of a journal row cannot change without the row version

The test walks the body schema and the row and mutation kind tables, collects every closed set (a
row kind, a mutation kind, each enum, literal or discriminant), and compares them with a snapshot
recorded beside the row version. A new value makes older builds go read-only, so it fails until
the reader ships first or `v` is bumped and the snapshot updated. Tags a catch-all arm accepts as
any string (block types, goal states) are listed apart: older builds read a new one as-is.

* feat(native-chat): a body or plan subject of a newer kind is kept and the chat stays writable

An item body kind and an approval subject kind this build does not know now read through the
same catch-all blocks and goal states use (`openDiscriminatedUnion`), instead of making the chat
read-only. The item is kept, drawn by nobody, and ignored by everything that reads items (turns,
prompts, status); a rewind carries it as it was, kept by its place like every other row. An
approval whose subject this build cannot draw shows its `detail`, which Orca's writers fill with
the subject's text. A sent message of a kind this build does not know stays a newer build's.

* fix(native-chat): rewind narrows a retained body by its kind before normalizing it

* fix(native-chat): one chat that cannot open no longer stops the startup restore of the rest

* fix(native-chat): a damaged chat fails to load and nothing is deleted

A row this build cannot parse, a gap, or an epoch without its first row used to
be repaired on open: every row from the damage on was deleted and a rebuild from
the provider transcript was attempted. The open now fails through one refusal
(failLoadOnJournalDamage, journalCorrupt), every row stays, and a damaged
per-chat file is kept whole and never copied. A newer build's row still wins
and keeps the chat read-only. The body classifier for closed-set values, the
repair marker and disclosure, and journal recovery from the transcript go.

* chore(native-chat): no reset or adapter left on the open's fixtures

* feat(native-chat): an approval of a newer Orca's subject kind can only be cancelled

Desktop and phone show its detail and the line "This request needs a newer
version of Orca.", disable every answer, and keep the card's cancel, which ends
the turn. The chat stays writable.

* test(native-chat): the closed-set guard says a missed version bump fails older builds' load

* test(native-chat): the closed-set guard names what a missed version bump does

* fix(native-chat): a row the reader rejects is never written, and a chat that cannot load keeps its tab

Every journal insert reads its serialized row back with the reader inside the
write's transaction and refuses one it rejects, so Orca's own writer can no
longer leave a chat that fails to load. A restored chat whose open fails keeps
its tab and says why when opened. An epoch named with no rows is founded afresh
again, deleting nothing. The at-rest test now expects a damaged chat to be
refused; the replay gate keeps its 2026-09-11 evidence as it was run.

* fix(native-chat): a newer Orca's approval subject is carried as it was, and its card cancels with or without a turn

The approval subject's type is open, so code that reads a plan narrows first; the
host's prompt bounding carries an unknown subject instead of rebuilding it as a
plan, which threw in every start's stale settlement. A Codex rewind keeps a
newer Orca's item in its place. A whitespace-only tag is damage. The card's
cancel reaches the host without a running turn on hosts that take that. A
provider row the reader rejects ends its turn as interrupted and the next send
works. A guard fails if an approval subject kind is added before clients can be
gated (STA-9262).

* fix(native-chat): a card's cancel sends nothing without a turn again, and rewind keeps a newer row after any held row

The host's cancel request has to name a turn on every version, so the turnless
prompt cancel is reverted on desktop and phone. The rewind merge moves its anchor
for every row the provider still holds, so a newer Orca's row stays after one
whose kind this build does not know.

* fix(native-chat): a card this build cannot answer leaves the composer open, and a send starts a turn

An approval of a subject kind this build cannot draw, raised by a newer host's background agent
while no turn runs, left nothing to press: its answers are disabled, its cancel needs a turn, and
the desktop composer gave the card its slot. A send the host queues waits behind any pending
prompt, so even the phone's open composer only queued.

While every pending prompt is one this build cannot answer, the desktop composer stays open, and
desktop and phone send without asking to queue: the send starts a turn, and the card's cancel then
settles it. A chat a dead run left is unaffected: opening it already cancels those prompts.

* feat(native-chat): a chat a newer Orca saved fails to load and says to update, with nothing to send into

Opening a chat a newer Orca saved (a row kind, batch-change kind or sent-message kind this build does
not know, a newer row version, or a newer history store) used to open it read-only: the history
shown, the composer locked with a reason, every control greyed. Now it fails the load, like a
damaged chat, with its own words: "This chat was saved by a newer Orca. Update Orca to open it."
Every row is kept. The read is final, so the pane stops retrying; reopening the tab reads again.

A chat whose load failed for good (damaged, or a newer Orca's) offers no composer under the error,
on desktop and on the phone, so the failure is said once and no send can be refused a second time.

A restart offer for a newer Orca's chat is spent without a word: no failure filed, nothing counted.

Removed with the read-only mode: the journal's read-only latch and every check of it, the history
page's readOnly field (never released), the cursorless reconnect, read-only paging, the composer
lock and placeholder, the greyed controls, and the resume exclusion.

* test(native-chat): a newer Orca's records open no chat, and a status fake carries its submissions

* test(native-chat): the status fake's cast says what the feed reads

* fix(native-chat): a chat's read that failed for good takes the whole pane, over a loaded transcript too

* test(native-chat): the final-read-failure test names its reasons

* fix(native-chat): a newer Orca's chat keeps its restart offer, and its refused load is logged once

* refactor(native-chat): the newer-Orca chats a restart listing skips live beside the candidate reader

* fix(native-chat): a refused chat load keeps where it failed, so the log names it and a new reason logs again

* chore(native-chat): the reducer's window merge back where main has it, and comments say a newer Orca's chat fails to load

* test(agent-hooks): the rename test's journal fakes carry submissions, as a journal snapshot does

* test(agent-hooks): the rename test's journal fakes say what the status feed reads

* fix(native-chat): Dismiss all ends the restart offers this Orca lists, and keeps a newer Orca's hidden ones

* test(native-chat): a resend against a newer Orca's store answers unknown, and the phone says nothing beside the read's words

This build never opens a chat a newer Orca's database holds, so a resent send id there cannot be
answered from its journal: it answers "outcome unknown", never a refusal and never a made-up
record, with no second delivery and no write. On the phone, a send error left beside a read that
failed for good is not shown; the pane keeps only the read's words.

Subject: [PATCH 017/167] fix(codex): stop prompting a Codex restart when only
 its home changed (#25421)

* fix(codex): stop prompting a Codex restart when only its home changed

A Codex terminal that outlived the move to ~/.codex was blocked behind "This
Codex session is using an outdated configuration" until the user restarted it,
which starts a fresh codex and ends the conversation. That terminal keeps
working on Orca's old Codex home, which is refreshed from ~/.codex, so the
change did not need the user's answer; the prompt also never appeared for
Codex in Git Bash terminals, whose process tree Orca cannot see through.

The restart prompt now covers only an account switch, which the user caused.
The pane record keeps its home route, which the retained-home refresh and the
shared-server check still read; only the prompt and the custom-home downgrade
that existed to keep it from guessing are gone.

* refactor(codex): drop what the home-route prompt left behind

- Record a pane's own CODEX_HOME override as-is. The filter that kept only
  overrides Orca could re-derive existed for the removed route comparison;
  its one remaining reader, the shared-server check, returns null for the
  shared-home route those panes record either way.
- Treat custom-home like shared-home in resolveCodexPaneHome: the removed
  downgrade only wrote it without an override, so it never named a home.
- Inline the restart notice key; its route/account prefix was its only job.
- Delete the two pane-local override tests, including a POSIX-only one that
  still expected custom-home and would have failed on Linux and macOS CI.
- Cover the account recheck branches the deleted route-recheck file was the
  last to exercise: main reporting a pane current, and main not answering.

* refactor(codex): retire custom-home and the last re-check helpers

- Read an older build's custom-home record as shared-home, which it always
  was, and drop custom-home from the route type and every check.
- Delete shellStartupCodexHomeOverrideMatches and its comparison helper;
  nothing re-checks a recorded override any more.
- Build the pane launch record in one return: the route is always set, and
  only a resumed launch differs, in how it picks the account.
- Drop the restart dialog's notice key; its focus effect now depends on the
  pane and both account labels directly.
- Give the account recheck test a typed window stub, so CI's type-assertion
  gate passes, and remove timing entries for deleted test files.

* fix(codex): drop the removed dialog strings main added to es.json

* refactor(codex): stop recording a pane's custom CODEX_HOME

The pane record kept a pane's CODEX_HOME override so the removed route
prompt could re-check it later. Its one other reader, the shared-server
check, only looked at it for a real-home pane, and a custom CODEX_HOME
always routes a pane to Orca's mirror, so it was never used.

Drop both record fields, their validators, equality checks and spawn
plumbing. getCustomCodexHomeOverrideForLaunch folds into the existing
hasCustomCodexHomeOverrideForLaunch, and real-home resolves to ~/.codex.
Records from older builds still parse; the parser keeps only known keys.

The fish test's decoy no longer sets CODEX_HOME, so the boolean check
still fails if the launch env XDG_CONFIG_HOME is ignored.

* test(codex): drop setup the yes/no CODEX_HOME checks no longer need

Subject: [PATCH 018/167] Fix legacy worker recovery snapshot timing for
 rollback safety (#25413)

* test: add legacy worker recovery persistence snapshot budget tests

Rollback requires the final stored state after processing all workers,
not intermediate snapshots after each candidate. This bounds the snapshot
count and preserves concurrent edits during the durable write.

* fix test

* clean up code

Subject: [PATCH 019/167] fix(jira): read a missing or malformed Jira status as
 disconnected (#25579)

The paired web client has no Jira preload, so window.api.jira.status()
resolves undefined from the fallback proxy. Since #24376 the first status
check stored that undefined and the sidebar crashed reading `.connected`.
Parse the status reply at the runtime-client boundary so every reader
gets a well-formed JiraConnectionStatus.

Subject: [PATCH 020/167] feat(agent-launch): keep long prompts off the launch
 line and paste them after readiness (step 1 of 7) (#24257)

* feat(agent-launch): host-side prompt delivery for agent.launch

The host's agent.launch typed any launch prompt into the shell as part of the
launch command. A long or multi-line prompt then ran line by line in the
shell, and an agent that never showed readiness or crashed at startup had
nothing guarding where its text went.

agent.launch now carries a prompt on the typed line only when the line stays
one line, control-free and at most 512 bytes; otherwise the agent starts
clean and the host pastes the prompt once the agent's own ready signal fires
(bracketed paste plus its composer marker or a quiet render, read only after
the shell's last hand-off, never while the pane's own shell is proven in
front), with main's draft-paste bytes and an Enter 50 ms later. Orchestration
worker starts wait on tui-idle as before. A replay-safe launch admits and
claims its ledger row in one write, Qwen Code gets a second Enter, the
desktop and phone share one launch-refusal classifier, and hosts advertise
agent.launch.prompt-carry.v1.

Split out of #23748, which moves the desktop source-control buttons onto
this path.

* fix(agent-launch): keep a short-lined multi-line prompt on a local zsh launch line, as main did

#24257 moved every multi-line or over-512-byte prompt off the typed launch line and pasted it after readiness. The phone's AI buttons and review notes, whose multi-line prompts main typed whole into zsh, then reached Claude 0.5-3 s later and their RPC reply waited for the paste.

The host now names the shell a local macOS or Linux line is typed into, the way the spawn picks it, and a multi-line prompt rides a zsh line when every line is at most 512 bytes and the whole line at most 8 KB. A real-zsh test types such a line through Orca's own ready barrier and startup write, including when a slow user config makes the write land early. Elsewhere the measured unsafe cases keep the paste: bash 3.2 runs multi-line lines piecemeal, fish drops an early multi-line write, and any shell loses a line over 1 KB written early.

* test(agent-launch): keep the real-zsh launch-line test out of the Windows lane's gate scan

The Windows lane registration check read `const ZSH_PATH = process.platform === 'win32'` (the head of a multi-line ternary) as a Windows-true flag, so `describe.skipIf(!ZSH_PATH)` looked like a Windows-only suite. The file is POSIX-only; the zsh lookup is now a function.

* refactor(protocol): move the agent.launch capabilities into their own module

Main's protocol-version.ts sits at the 300-line cap, so the prompt-carry capability pushed it over. The four agent.launch capabilities and their doc move to agent-launch-runtime-capability.ts, re-exported by name and spread into RUNTIME_CAPABILITIES at the same position; the advertised lists and every export are unchanged.

* refactor(protocol): import the agent.launch capabilities from their own module

`export *` from protocol-version left the four names undefined under the mobile recording loader, which resolves a relative import through a Proxy with no own keys, so 37 phone recordings lost agent.launchReplay. Importers now name agent-launch-runtime-capability directly; protocol-version only spreads its list.

* refactor(agent-launch): drop the unshipped viewMode field and trusted local caller id

Both were inert in step 1 and existed only for step 2. agent.launch will become a
public plugin API, so every wire field is permanent once shipped; a top-level
viewMode reads as "choose terminal vs chat", which the host decides. Step 2
introduces placement and view intent under a placement object instead.

* fix(agent-launch): read Codex's provisional startup from the rule files' hold anchor

Main (#24375) moved Codex's provisional-header check into codex.json's
provisional_startup hold anchor and deleted codex-terminal-readiness.ts, so the
launch readiness hold now asks showsHoldAnchor, as main's own settled check does.

* fix(agent-launch): hold rule-file name titles to quiet for a launch, and census the zsh fixture

Main (#24375) answers a name-only title from each agent's rule file ahead of the
sustained-title lane, so gemini.json's name_title settled a launch readiness wait
on the shell's auto-title while Gemini was still booting. A launch now asks quiet
of every weak idle verdict, as that lane did.

Main's readiness census requires a recorder for every runtime fixture; the zsh
prompt recording is a non-agent control. Gemini's synthetic baseline is
regenerated for this PR's stated change: a bare gemini title is no longer its
rest mark, so name-only rows settle weak, and a fresh working or blocked status
is no longer overridden.

* fix(agent-launch): paste a launch prompt only when the launched agent is proven in front

A launch pasted its prompt unless a shell was proven in the terminal's
foreground, so any read that could not prove one let the prompt through. After
an agent exited at startup, its shell turned bracketed paste on at the next
prompt, readiness fired on it, and the prompt was typed into the shell:

- macOS: a pane runs its shell under login, so the process-group fence's root
  was never the shell's group and never proved it; the cached foreground name
  could also still name the exited process.
- Windows Git Bash and WSL: the shell-alone-in-its-job check never answers.

Now one fresh read of the terminal's foreground decides: agent, shell or
unknown. Only 'agent' lets a write through (paste, Enter, second Enter, reused
panes too); 'shell' still drops a ready signal. A Windows host never proves the
agent, so there the launch line carries the prompt at any size, as on main.

* test(agent-launch): cover the Windows QA stub, a grok override that exits at once

* fix(agent-launch): keep the local socket alive while a prompted launch waits for its agent

A launch with a prompt now waits up to 60 s for the terminal agent to be
ready before it writes the prompt, and reports not-delivered when the agent
never is. The local runtime socket closes a connection idle for 30 s unless
the request is a long poll, so a launch whose agent exited at startup lost its
reply and the caller saw 'runtime closed the connection' instead of
not-delivered. Classify a prompted agent.launch and agent.launchReplay as a
long poll, as orchestration.workerStart already is for the same wait.

* refactor(agent-launch): narrow the launch params by 'in' instead of a cast

* fix(agent-launch): find a launched agent behind a wrapper that leads its process group

A tcsh or nu launch line runs the agent from /bin/sh '<script>', and a
wrapper script that does not exec its agent does the same: the wrapper leads
the terminal's foreground process group and the agent is a member of it. The
fresh foreground read names the group's leader, sh, so a prompted launch was
refused or pasted late (M4Air tcsh: 2 of 4 not delivered, 2 pasted ~9 s late).

Before that read, take the host's process-group observation as positive proof
when it names the launched agent among the foreground group's members and is
younger than a ready signal's quiet window. It never proves a shell.

* fix(agent-launch): judge the foreground-group proof by when its capture began, not how long ps took

The age the host stamps on a process-group observation runs from the start
of its whole-machine ps, so on a loaded Mac a capture begun after the read
was asked for still read as older than 1 s and the proof was dropped. Count
an observation whose capture began after the read was asked for, less the
window a shared capture is reused across.

* test(agent-launch): keep the crash-guard live test out of the Windows lane's gate scan

The Windows-lane registration scan read the const assigned from a platform
check as a Windows-only gate, though the suite runs everywhere but Windows;
find zsh in a function instead, as the real-zsh typed-line test does.

Under load the fresh foreground scan can fail to answer, which lets the
shell's prompt settle readiness (2 of 4 paired runs). The guard still refuses
that write, so assert the refused write, the property that must always hold.

* perf(agent-launch): read a local pane's foreground from its own terminal, not the whole process table

The foreground read that gates every launch paste ran the daemon's
inspectProcess capture and then a fresh scan, each a whole-machine ps; the
fresh one also waits for any capture already running before it starts its own.
Measured here at load 5: 1.2 s a read (M4Air QA: 3.4-5.0 s, and worker starts
17.6-32 s against main's 9-12 s at load 25-84).

On a local macOS or Linux host, take the pane's root pid from the provider's
session inventory and run one ps limited to that pane's terminal. Its
foreground process group decides: the launched agent or any non-shell member
is the agent (a wrapper that did not exec its agent leads the group), a group
of shells alone is the shell. Same pane, same verdict: 2.7 ms a read. SSH hosts
keep the relay's observation and name.

* test(mobile): re-measure the web app's script sweep after agent.launch's capabilities moved out of protocol-version

The mobile web bundle check failed at 124 assets against a ceiling of 123. Main already sat
exactly on that ceiling: its sweep table read 69 scripts at 16 routes while the tree builds 73,
the whole margin of 4. This branch imports the agent.launch capabilities from their own module,
so protocol-version is no longer pulled into the root layout and four other routes. That moves
which routes share which modules, and the Qoder capability module, imported by protocol-version
and the AI-vault resume path, no longer shares an importer set with anything, so it gets a chunk
of its own: 74 scripts.

The fence says to re-derive the bound rather than raise it, so the sweep is re-measured on this
head (every prefix of the sorted route list). The worst route now adds 10 scripts (session), not
9, which moves the pinned shell crossing from 32 to 30 routes; main re-measured on its own lands
on the same crossing.

* fix(agent-launch): a worker's brief needs its agent found in front, and Grok's start answers on its composer

A paired-server worker start whose agent exited at startup typed its brief into the server's
shell, which ran it: the idle wait can settle on a shell back at its prompt, and the brief was
written with no foreground read. Both worker-start paths now check before each brief write, as a
launch prompt is checked: on a host that can find the agent in front it must be there; on one that
cannot (Windows) a shell proven in front still refuses, and anything else writes as before.

A Grok worker start waited ~10 s more than main: its only rest signal is its bare name, which a
launch holds to quiet output, and Grok animates its logo for ten seconds after its composer glyph.
A worker start for an agent whose rest signal is its bare name and whose composer draws a marker
(Grok, DSH, mimo-code) now also answers on that marker, whichever comes first.

Subject: [PATCH 021/167] fix(mobile-chat): a failed message's text is added to
 the draft, and an expired resend no longer blocks that text (#25149)

* fix(mobile-chat): a returned message is appended to the draft, and an expired resend id is spent

* test(mobile-chat): leave the idempotent append to the shared rule's own test

* docs(native-chat): say a whitespace-only draft counts as empty

* docs(mobile-chat): don't overclaim where returned text survives

Subject: [PATCH 022/167] feat(native-chat): answer /context in chat view for
 OpenClaude and OMP (#22294)

* feat(native-chat): answer /context in chat view for Claude

Over a terminal-backed chat, Claude's /context paints a grid only the hidden
terminal sees and records nothing in the transcript, so the chat showed
nothing. The chat host now answers it itself: the transcript decoder keeps
each assistant response's API usage and model, and the composer replies with
the same estimate the CLI statusline shows (input + cache tokens against the
model's window) instead of typing the command into the PTY. The command is
also listed in the curated Claude catalog so the slash menu offers it.

* fix(native-chat): only state a /context window the host can establish

The /context answer sized the window from the transcript's model id, which
never carries the [1m] suffix, so a 1M session read as 200k (e.g. 450k / 200k,
225%). The window now comes from the session's tracked model resolved through
the host CLI's own model listing (the resolvedModel field the list_models probe
already returned), and only a [1m] id that matches the model the transcript
last answered with is sized; anything else reports the used figure alone.

Also:
- Offer /context only in the desktop terminal-backed composer; the shared
  catalog is mobile's too, and mobile cannot answer it.
- Answer a typed /context even with images attached, as the picker does, and
  keep the attachments armed instead of sending them to the terminal.
- Report nothing until a response lands after a /compact or /clear sent from
  the chat, instead of the pre-compaction size.

* test(native-chat): pin resolvedModel through Claude model discovery

* fix(native-chat): say /context is unavailable when the host never reports usage

A host that predates usage decoding, or a scraped view, decodes Claude's
replies without a model or usage, so the chat promised an answer after the
next response that would never come. Once the agent has answered and no
answer names its model, say usage is not available for this session.

* feat(native-chat): answer /context for OMP instead of Claude

Claude and Codex answer /context themselves in the structured chat lane, so
the terminal-backed Claude answer, its [1m] window rule, and the resolved-model
plumbing through the model listing go away.

OMP's /context only paints a panel inside its TUI. The OMP decoder now keeps
the provider, model and usage of each reply (none for aborted or errored
replies, which OMP's own gauge skips) and turns compaction rows into the
existing compaction boundary. The OMP model listing keeps each model's
context window, and the chat answers /context from the last reply's prompt
size against the window of the provider/model that served it.

* feat(native-chat): show OpenClaude's own /context report in chat

OpenClaude writes its /context grid to the transcript as a
<local-command-stdout> row, which the chat hid as harness noise. The live
message preparation now turns the stdout row that answers an opted-in command
(/context for OpenClaude) into command output with the ANSI colors stripped,
and the notice row renders command output in monospace so the grid keeps its
columns. Replies to other local commands stay hidden, and Claude is not opted
in. OpenClaude's slash menu now lists /context; Claude's does not.

* test(native-chat): pin OpenClaude /context output through live message preparation

* test(native-chat): pin the OMP context window through model discovery

* test(native-chat): pin monospace rendering of command output

* test(native-chat): restore the notice row suite the command-output test replaced

The previous commit rewrote NativeChatNoticeRow.test.tsx wholesale, deleting
main's compaction, tone, plan, provider-notice and old-reader coverage. Restore
it and pin monospace command output through the message row instead.

* fix(mobile): keep OpenClaude /context off mobile, which cannot show its report

The shared slash catalog now lists /context for OpenClaude because the desktop
chat surfaces its transcript reply. Mobile's transcript fold does not, so the
command did nothing there. Mobile now offers the catalog minus commands answered
only by a surfaced reply, which returns its OpenClaude menu and send
classification to main's behavior.

* refactor(native-chat): drop the unread estimated flag from context usage

Left from the earlier design; the answer text states the estimate itself.

* fix(native-chat): keep /model replies hidden after an OpenClaude /context

Skill surfacing ran first and rewrote non-catalog envelopes such as /model into
plain user text, so command-output pairing no longer saw them. A later /model
reply then paired with the earlier /context envelope and appeared in the chat.
Pair outputs against the raw envelopes before skill surfacing.

* fix(native-chat): word the OMP /context answer for a compacted session and show it as an aside

After a compaction the agent has already answered, so the unknown-usage
line now promises the next response instead. The host answer is one
sentence, so it draws as the muted line it replaces rather than a
monospace grid. The provider/model selector now comes from one helper
shared by the OMP listing parser and the answer, and new tests drive
real OpenClaude and OMP transcript lines through the decoders.

* refactor(native-chat): pair command replies by row link and declare /context replies on the catalog

A `<local-command-stdout>` row now answers the command row its `parentUuid`
names, carried on decoded messages as the optional `parentId`, instead of the
newest command row at or before its timestamp. A reply with no loaded linked
row (older host, command outside the tail window) stays hidden.

How each agent's `/context` is answered is declared once, as `reply` on its
catalog row (`composer` for OMP, `transcript` for OpenClaude). The slash menu,
the composer's answer, the transcript surfacing and the mobile catalog all
derive from it, and both send paths share one intercept. Mobile no longer lists
OMP `/context`, which did nothing there.

* perf(native-chat): skip command-output surfacing for agents that declare no transcript reply

Every Claude-format row now carries its parent link, so once a session holds any
local-command reply (/model, /compact) the surfacing pass built a map of every
message on each live update and changed nothing for agents like Claude. Agents
whose catalog declares no transcript reply now return before the scan.

Subject: [PATCH 023/167] fix(native-chat): the agent's exit ends its record,
 and an unconfirmed stop is joined instead of held (#24862)

* fix(native-chat): a child's root exit is reported even during its close, and bookkeeping after it never reads as unproven

- Both connections report the root process's exit once, with `expected` set when a close had
  begun. A close that came back unproven and whose root exits later is finished by the adapter,
  and its end reaches the host like any other.
- A Claude close whose resume-point write fails after the exit was proven, and a Codex close whose
  terminal row is refused, now end the session and report the failure, instead of keeping a dead
  child indexed as if its exit were unproven.
- A Codex close whose forced tree kill can't prove the descendants gone but saw the root exit
  reports the descendants and counts the root exit.
- Every child exit with an identity, expected or not, is forwarded to the host.

* fix(native-chat): the exit ends the child's record; an unfinished stop is the child's own close, which everyone joins

- The host keeps no stored "stop still owed" record any more. A stop begins the child's close
  (`child.close`), which lives on the child and ends with it. A second Stop, the idle reaper,
  quit, a send and an option/answer/goal/rewind all join that close instead of retrying a
  separate obligation.
- A caller waits on the close only as long as the step deadline; the close itself is never
  abandoned. A proof that lands after every caller stopped waiting reaches the host as the
  adapter's report of that exit, which ends the record through the same handler.
- Once the exit is proven, draining, settling, the lease release and the adapter's
  acknowledgement are each attempted and reported on failure; none keeps the child on record.
  A start, and the handle's close, write a release that failed from this host's proof of that
  exit, so a failed write never refuses a send.
- A start that meets a close still unverifiable is refused with `previousExitUnverifiable`, so the
  queued message is rejected with a send-again reason; nothing is held and nothing starts beside
  the old process.
- The idle sweep goes back to idle reaping only.
- Removes #24333's retry entry points, the wait row and its hold rule, the ask/failure cursors on
  the stored record, and the stop's own wake.

Tests replace the #24333 unproven-stop test: a send joining an unproven close and an in-flight
one, a late proof past the caller's bound, a root exiting after its close gave up, a proven exit
whose resume-point write and lease release both failed, an unverifiable close rejecting the send
and refusing an option change, a surviving descendant, quit and the idle reaper; and Codex's
unverifiable, late-exit and joined-close cases.

* fix(native-chat): a message refused because the old process's exit is unverifiable says so, and to send again

The start failure for a refusal with reason `previousExitUnverifiable` reads "Orca couldn't
confirm Claude's previous process ended. Send your message to try again." instead of "Claude
couldn't restart." The status-row kind and the refusal reason stay in the shared lists for rows
and hosts that still carry them; the catalogs keep one sentence for both.

* fix(native-chat): a close's verdict is the root's exit alone, and what follows it is logged

- A Claude close resolves as soon as the root's exit is proven: the session ends and its `ended`
  report goes out then. Saving the resume point runs afterwards and a failure is logged, so a slow
  or hung write never reads as an unproven exit or keeps a dead child on record.
- A root that exits after its close came back unproven finishes that close through the same path
  as any close, so the session's child work is published as ended (background tasks and subagents
  no longer stay shown running for a dead agent), and a failure there is logged.
- Codex logs a refused final row, and reports a root exit whose forced tree kill could not prove
  the rest of the tree gone the way Claude does, so the host logs it and blocks nothing.
- Both adapters take the host's logger for this bookkeeping.

* fix(native-chat): one handler ends every child's exit, and a join waits on the adapter's own close

- One exit handler (`structured-agent-session-child-exit`) ends a child's record for an exit
  expected or not. `expected` only changes what the chat is told: the stop's cause, its end at the
  stop's ask, the settlement id, and no crash outcome row. The lease release keeps the exit's
  evidence; the handoff guard, lifecycle barrier, sink release and adapter acknowledgement apply to
  both. A Claude journal-sink failure ends in the same step as its stop, as Orca's own fault.
- Joining a close is asking the adapter, whose close is memoized while it runs and bounded by its
  own kill escalation; the host keeps no attempt of its own and no 10 s caller bound. An ask after
  a close came back unproven runs the stop again.
- A close's end is stamped where its stop was asked for (a repeated ask moves it), so the closed
  chat and failed start checks order a message accepted meanwhile after it.
- A start refused because the old exit is unverifiable rejects what was queued in the same step.
- The end of a close the host asked for no longer waits on the cross-session recovery chain.
- The kill no longer waits for the stop event's write; the journal writes rows in order.

* fix(native-chat): an exit's lease release lands whatever the length of its reason

A crash's reason can carry kilobytes of the provider's stderr, and a lease whose death detail is
over 512 characters fails the store's own check. The exit handler cut it, but the release a start
or the chat handle's close re-derives did not, so after a crash whose own release failed every
message was refused as not resumable until restart. The record's builder now cuts the detail to
the record's bound, so no writer can hand it one too long.

* fix(claude): a proven close waits at most 2 s for the output it already wrote

Once the root's exit is proven, the close still waited for the SDK's output reader to end. Something
outside the process tree that holds the output open would keep that close, and every send, Stop
and quit joining it, waiting with no bound. The wait is now bounded; past it the close resolves as
proven and the open output is logged.

* fix(codex): an exit reported inside Orca's close keeps the reason Orca closed it for

The connection reports the app-server's exit inside the close that ends it, so that report ended
every Codex close and replaced the close's own reason (for example, a provider frame that could not
be recorded) with the connection's stderr text in the ended record and the lease's exit evidence.
The session now records Orca's close with its reason, and the exit it ends keeps that reason. The
test connection reports its exit inside close the way the real one does.

* fix(native-chat): quit stops delivery before it drains exit recovery

Every exit now wakes delivery, and teardown drained exit recovery before it stopped delivery, so an
exit settled in that window could start a fresh agent that teardown then killed. Teardown stops
delivery first; queued messages wait for the next launch.

* docs(native-chat): the unverifiable-exit refusal no longer names a caller's wait

The caller's bounded wait was removed; the comment describes the close as it is now.

* fix(native-chat): a stop whose kill did not take is logged, and the next ask kills again

When a close's kill leaves the agent's root running, the host now logs it. Tests pin what a later
ask does: each connection runs its whole stop again (Codex sends SIGKILL a second time), refuses
input meanwhile, and proves the exit once the kill takes.

* fix(native-chat): a start refused over the old process says Orca couldn't stop it

The host reaches an unverifiable verdict only after its own kill left the agent's root running, on
the machine that runs the agent, so the sentence now says that: "Orca couldn't stop {agent}'s
previous process." The refusal reason, failure kind and wire shapes are unchanged. The host test
also checks the failed kill is logged.

* docs(native-chat): an unverifiable close verdict is a root that survived the kill

The host's close runs where the agent runs, so lost contact never yields this verdict; the comment no longer says it does.

* fix(native-chat): a kill that did not take is reported once, by whoever met it

The log added at the close fired beside a Stop's own failure report for the same event. A stop
still reports it through its failure; a send or option change refused over it now logs it at the
refusal, the only place it is otherwise invisible.

* test(native-chat): a second Stop joins a close the first could not prove and retries its kill

* fix(native-chat): say a start refused beside an unstopped process plainly

The rejection now reads "Couldn't stop {{agent}} from before. Send your message again to try once more."
This kind has its own send-again step; every other failure keeps "Send your message to try again."

-// Stopping one structured session's provider child and handing its lease back.

 //
 // Teardown is a DATA list, not a method body, for the reason this file exists at all: the host
 // tracked which sessions were live in a map, and tore them down at three unrelated call sites
 // (app quit, handoff to a TUI, and error cleanup). Closing a chat was never wired to any of them,
 // so a provider child outlived the chat that owned it for the whole app session.
 //
-// ORDER. The provider child stops FIRST. Closing it is not silent: the codex adapter emits its
-// `ended` event and flushes coalesced text as part of shutting down, and those are the rows that
-// clear the running-turn marker. Draining or closing the sink ahead of that drops them, which
-// leaves the durable journal claiming the agent is still working — a worse outcome than the leak
-// this teardown exists to fix. So: stop the child, drain what it emitted on its way out, then let
-// the sink go. The one step ahead of the stop only reads, for quit's resume offer.
-//
-// FAILURE. A step that fails ABORTS the rest. `closeSession` returning false means the child's
-// exit was not proven and the adapter has deliberately kept the session indexed so a retry can
-// reach it; forgetting it anyway stranded the process forever and reported success. Leaving the
-// session in place is what makes the next close a real retry instead of a no-op.

Subject: [PATCH 024/167] feat(activity): filters, matching header, row
 right-click menu, and stay in the activity view (#25376)

* fix(sidebar): stop workspace reveals from leaving the activity view

Reveals are skipped while the activity view is showing, and activation no
longer lifts workspace-list filters there. Only explicit requests (Go to
workspace, reveal-current-workspace, Cmd+J project row, agent send target,
Cmd+1-9) switch to the workspace list via showSidebarWorkspaceList.

* test(sidebar): keep test harnesses out of the sidebarBody writer census

* feat(activity): workspace-origin filters and a matching options trigger

Activity view gains its own persisted Hide automation-created, Hide CLI-created
and Hide other-client agents toggles, applied through the existing activity
scope filter so the selected-row exemption and identity-preserving return keep
working. The options trigger now uses the workspace view's SlidersHorizontal
icon and shared numeric badge, counting every active activity filter, and Add
project stays visible so no header button shifts between views.

* feat(activity): right-click menu on activity rows

Open, Mark as read/unread, Go to workspace (real workspaces only), Copy (agent
title, plus branch and path for real workspaces), and Clear from list for
finished threads, reusing the row's existing actions and clearActivityThread.

* fix(sidebar): leave the activity view only once activation commits

Go to workspace and Cmd+1-9 switched the sidebar before activating, so a
blocked folder activation still left the activity view. Activation now owns
the switch via showWorkspaceList, applied after its failure gates. The
separate showSidebarWorkspaceList action and the one-line sidebar-body-reveal
module go away: setSidebarBody is the single writer, and the census pins its
callers.

* fix(activity): close the row preview when its right-click menu opens

* fix(activity): keep the row preview closed while its right-click menu is open

* fix(ui): give right-click menus the same solid surface as dropdowns

* fix(activity): match the agent row menu to the workspace row menu

* fix(activity): offer the same copy items as the workspace row menu

Subject: [PATCH 026/167] fix(relay): read reconcile's counter units after the
 cell lock (#25638)

reconcileReservationAccounting computed each cell's absolute reserved_requests
from leases read before lockCellRows, so a host placed in that gap lost its
unit: the counter went to 0 with one lease on the cell.

* test(terminal): restore the live fish fixture prerequisites (#24947)

A restored pane waits for the initial status replay before subscribing to
PTY output. This fixture never settled that replay, so fish printed its
mode-2031 arm before the renderer connected. Its PTY API also omitted the
reset-input listener required by the serializer, aborting attachment.

Settle and dispose the existing startup-snapshot registration and provide
the same reset-listener mock used by the other PTY tests. The real fish
child-stdin assertions and timeouts remain unchanged. No production change.

* fix(shortcuts): defer TUI editing chords in terminal-first mode (#24640)

Restack the original focused change onto current main, preserving every owned source and test blob and the merged CI contract and journal cleanup fixes.

* Skip store notifications when refreshed work items are unchanged (#24530)

An identical forced refresh previously returned an empty Zustand patch, creating a new root state and notifying every subscriber. It now returns the current state after renewing the existing freshness timestamp. Real row or metadata changes still publish once.

* Read project activity once while sorting the sidebar (#24549)

Reuse the existing pure recent rank once per actual entry tuple within each synchronous sort; discard the lookup after sorting.

* Skip impossible link and tag matches in docs search results (#24646)

* Skip impossible HTML matches when formatting docs search results

After the existing link-removal phase, skip the unchanged HTML regex only when the current string has no closing delimiter.

* Skip impossible link and tag matches in docs search results

Skip the five unchanged link regexes when their protected-code input lacks ]; skip the unchanged HTML regex when its post-link input lacks >.

* Decode complete transcript lines without copying their bytes (#24546)

Decode each single owned Buffer synchronously; preserve concatenation for multipart records and remove a redundant tail array copy.

* Clear unused speech worker timers after errors and exit (#24924)

Call the existing idle timer cleanup when private current-worker state is cleared; keep current-worker guards, transcript/error order, deliberate warmth and stop deadline unchanged.

* Reuse documentation search excerpts during result navigation (#24574)

Memoize the existing pure excerpt renderer by complete raw text for the current result array, retaining original rendering as a miss fallback.

* Append subagent handoffs without recopying their message list (#24672)

Append each message reference to its private call-local scope list; retain the final merge and existing ordering.

* Cancel plugin retry timers when their fetch is replaced (#24700)

Reuse the existing timer clear block immediately after the fetch generation advances; preserve live retries and all state publications.

* Avoid rebuilding visible file paths for single-row selection (#24743)

Skip the visible path array only for keyboard replacement selection; the existing replacement branch never reads that order.

* Reuse prepared reads while searching saved agent conversations (#24535)

Use schema-complete session columns to enable the existing bounded statement cache without caching result rows.

* Reuse discovered mobile chunks during static traversal (#24774)

Iterate the existing live visited Set in FIFO discovery order instead of maintaining a second shifted queue; both actual callers own untouched esbuild JSON metadata.

* Skip unused image-size calculations in mobile web browser requests (#24941)

Use the existing mobile density budget only for mobile view; pass the existing constant to the existing assembler for web/default mode, where that argument is discarded. No cache, policy, request or native path changes.

* Skip diff analysis after a result has been discarded (#24711)

Move the unchanged pure render-limit calculation after both existing generation and section-token rejection fences.

* Skip late browser grab toasts after their surface closes (#24727)

Reuse the existing mounted-owner ref at the toast presentation entry while preserving all admitted extraction/screenshot and clipboard completion.

* Classify native chat waiting messages once (#24771)

Use the existing native filter traversal to populate a fresh waiting array, keeping the original predicate, policy, projection and output ordering while classifying each actual private slot once.

* Skip discarded Kanban pruning for an empty selection (#24782)

Guard only the existing open pruning branch when both its private selected Set and nullable anchor are empty; retain all original pre-guard projections and nonempty/anchor-only/public-helper behavior.

* Index discovered test files once during shard selection validation (#24532)

Verified selection plans previously validated each selected filename with a scan of all discovered files. One per-call Set now handles membership checks. Exact source/discovery checks, nonempty selection, fallback to all tests, shard balancing and manifests remain intact.

* Clear the watchdog benchmark heartbeat when CPU sampling fails (#24802)

Move the existing initial CPU observation and histogram enable inside the existing try/finally so their failures clear the sampler's owned heartbeat, preserving successful operation order and original errors.

* Reuse the parsed notification when leasing a push delivery (#24645)

* Skip renderer callbacks after their request has ended (#24631)

Reuse the existing pending-request identity check before starting its deferred renderer callback.

* Decode single-piece saved-session tails without copying them (#24632)

Decode the existing owned Buffer directly when the EOF tail has one piece; preserve the existing concatenation for multiple pieces.

* Avoid irrelevant scroll-action searches in Mac snapshots (#24731)

Check the current pure action name before searching for vertical scroll actions in the same immutable array.

* Stop copying every retained browser page before attachment (#24553)

Find the first page/generation match directly in the existing insertion-ordered Map instead of copying all page references into an array.

* Reuse event byte sizes when relay watchers notify several clients (#24558)

Store the existing grouped numeric byte-size array on the already call-local watcher batch sizing object, for reuse by later chunking clients.

* Stop building unused import candidates in the test planner (#24611)

Replace the existing ordered extension map/find with a loop that forms each candidate only when its existing lookup is reached.

* docs(terminal): explain local macOS/Linux shell startup files

* test(terminal): restore the live fish fixture prerequisites (#24947)

A restored pane waits for the initial status replay before subscribing to
PTY output. This fixture never settled that replay, so fish printed its
mode-2031 arm before the renderer connected. Its PTY API also omitted the
reset-input listener required by the serializer, aborting attachment.

Settle and dispose the existing startup-snapshot registration and provide
the same reset-listener mock used by the other PTY tests. The real fish
child-stdin assertions and timeouts remain unchanged. No production change.

* Use the measured pnpm lookup policy automatically in hosted root CI (#24951)

* Select lookup automatically for the measured hosted root-install profile

* Record hosted automatic-mode cold cache publication proof

* fix: bound remote generation setup and honor OpenCode option terminators

Count execution-host profile resolution inside the existing request deadline, cancel its waiter promptly, and pass only the remaining time to the child. Shared bounded profile probes keep their existing cache lifetime; the SSH transport margin is unchanged.

Read OpenCode output format from active final-argv options before -- so literal prompt arguments cannot select the JSON finalizer.

Fresh exact-source controls reproduce nine failures before; 139 related checks pass after, including primary/fallback delays, deadline boundaries, cancellation, parser metadata, and SSH lanes. Node typecheck and strict changed-file lint pass.

* test(jcode): measure the gate against the synchronous path, not the clock

The absolute 1s bound was the flake CI shard 3/8 hit: it is tight enough to catch
a synchronous gate on an idle laptop and too tight on a loaded runner. Measuring
the same POST both ways on the same machine makes the claim a ratio, which is what
the test is actually about. Mutation-checked: a synchronous gate reads 6120ms
against a 1517ms observer.

* test(jcode): drop the wall-clock gate assertion

The bound was machine-speed sensitive and flaked on CI shard 3/8 at 1525ms. The
structural assertions (detached gate branch, foreground observer branch) and the
no-hang stdin drain cover the same contract without a timer.

* fix(jcode): address CodeRabbit review on #22539

- Windows posted no payload at all: the shared builder reads `payload@-` from
  stdin, which the gate has already drained and observer hooks never receive, so
  every Windows event was dropped. Write the env var to a temp file and pipe it.
- The daemon pre-warm never fired for daemon-host spawns, which is the default
  local path; it now runs there too, and from the final env so the daemon gets the
  hook port and token.
- A failed runtime-dir mkdir took down every local terminal, jcode or not.
- removeJcodeManagedHooks matched the raw line, so a user hook whose comment
  mentioned the managed script was deleted; matching on Windows never worked.
- A managed entry left by a copied home or a platform switch is now repointed
  instead of being reported as user-owned forever.
- The OSC colour skip only checked launchAgent, so a command- or telemetry-named
  jcode pane still leaked the reply into its composer.
- `['hooks']` and a commented scalar are recognised, instead of appending a
  second [hooks] table that makes jcode reject the whole config.
- A failed tool's error is marked as tool output rather than agent prose.
- The vault keeps a session's stored name, counts its tokens, and skips
  background_task and [Scheduled task] turns.

* fix(jcode): read the journal once per turn, key prompts by byte offset

The jcode prompt reader ran a synchronous bounded file scan plus a JSON
parse on every hook event. jcode blocks on pre_tool, so a turn that ran
four tools charged the user eight scans of latency it did not need — the
prompt cannot change inside a turn.

- Cache the journal read per pane, refreshed on the turn boundary that
  can change it. The cache holds the whole evidence record, since
  hasExplicitUserPrompt needs the transcript-evidence flag and not just
  the text, and it joins the existing pane-scoped lifecycle (close,
  rename, reset) rather than living in a module singleton.
- Key a journal prompt by its absolute byte offset instead of its
  region-local line index. The backward scan windows the file from EOF,
  so appending shifted every boundary and reminted the key for a prompt
  that never moved; a repeated turn_end then slipped past the same-hash
  dedupe as a second done event with duplicate telemetry.
- Pin the platform in the daemon pre-warm tests. The pre-warm is a no-op
  off POSIX, so the dedupe and retry cases would have passed vacuously
  on a Windows runner.

* fix(jcode): quote the managed hook path, drop tools from patch prompts

Three fixes, all on paths this PR could not exercise locally.

The managed hook command was stored as a bare path. jcode tokenizes that
string shell-style before exec'ing it directly (parse_hook_command,
crates/jcode-terminal-launch/src/lib.rs): unquoted whitespace splits, and
every unquoted backslash is consumed as an escape. So on Windows
`C:\Users\me\.orca\agent-hooks\jcode-hook.cmd` reached exec as
`C:Usersme.orcaagent-hooksjcode-hook.cmd` and no hook fired at all, and a
POSIX home with a space split into two arguments. Store the path
single-quoted (verbatim, backslashes included), falling back to double
quotes for a path containing a single quote. Existing bare entries are
already repointed by the stale-key path, and getStatus accepts both forms
so the repair is not reported as a user-owned hook. The quoting helper was
previously dead code that only tests called; the three production sites
now use it. isJcodeManagedCommand also normalizes separators, since a
`/`-only needle never matched a Windows entry.

Commit-message generation feeds a staged patch to `jcode run` as the
prompt — attacker-influenced text — while jcode's default profile exposes
shell, read, write, and MCP. Pass `--tool-profile none`, which resolves to
an empty allowed-tool set in jcode's config (base_allowed_tools), matching
the read-only posture claude (plan) and codex (read-only) already take.

docs/reference/jcode-hook-events.md was never actually in this PR: the
repo ignores docs/** and tracks reference docs by allow-list only, so the
captured-payload evidence four source comments point at was silently
dropped. Allow-list it.

* test(jcode): pin the tool-profile flag in the generation plan too

The argv assertion lives in two places; --tool-profile none only landed in
one, so the plan test still expected the unrestricted argv.

Co-authored-by: czzczz <chanzrz_zbf@foxmail.com>

* fix(text-generation): refuse an oversized argv prompt on Linux too

The pre-spawn size guard only ran on Windows. Linux caps a single argv
entry at MAX_ARG_STRLEN (32 pages, 128 KiB on a 4-KiB-page host) and
execve fails with E2BIG past it, so an agent that delivers the whole
prompt as one argument — jcode, and the other argv-delivery agents —
failed on a large staged diff with an error the user could not act on.

The cap is per-argument and in bytes, which is why it is not the Windows
line budget: 40k chars trips Windows and is nowhere near the Linux limit,
so folding them together would have refused prompts Linux runs fine.

* fix(jcode): register in main's remote-installer guard, drop our duplicate

Rebasing onto 853 commits of main surfaced two things the earlier branch
had hidden.

main already owns a guard for the issue-#7253 bug class
(`remote-hook-service-registry-coverage.test.ts`). This branch had added a
second, near-identical one — a parallel implementation of a test that
already existed, which is what AGENTS.md's reuse rule is about. Deleted
ours and registered jcode in main's, which is the one that has kept pace
with every agent added since.

Also fixes a missing separator in the mobile icon map. `pnpm tc` does not
cover `mobile/`, so only the session-route closure suite caught it.

* fix(jcode): decompose the four files jcode pushed over max-lines

Adding an agent tipped four modules past their line budget. AGENTS.md
forbids a `max-lines` disable or a per-file bump, so each is split on a
real seam rather than silenced:

- agent-catalog.tsx keeps `AgentIcon`, which 70+ files import, and the
  rows move out. The rows alone exceed the 300-line budget a `.ts` file
  gets, so they follow the primary/secondary split this repo already uses
  for commit-message agent specs.
- getAgentResumeArgv -> agent-resume-argv.ts, re-exported so the 18 call
  sites keep one import path.
- isDiscoverableSessionFile/pathSegments -> session-file-discovery.ts.
- remoteCodexSources -> remote-session-scanner-codex-sources.ts; Codex is
  the one remote agent with two CODEX_HOME roots.

Also:
- Records the readiness-census baseline jcode now needs. main added that
  gate while this branch was out; the fixture is the recorded 74-case
  matrix, not a hand-written one.
- Restores two entries a rebase resolution silently dropped from
  config/tsconfig.cli.json (gitlab/project-ref-parser,
  startup/shell-path-probe). Nothing to do with jcode; losing them was a
  conflict-resolution mistake on this branch.

* feat(native-chat): open structured chats on the paired Orca server that owns the workspace (#24205)

* fix(native-chat): a host admits structured sessions by client capability, not its own chat setting

A host's experimentalStructuredNativeChat decided whether any paired client could reach
agentSession.* at all, and whether session.tabs.* showed it structured tabs. That setting is the
host user's own launch preference: whether a new agent opens as a chat or a terminal is decided by
whoever launches it. Using it as admission control meant a client whose own preference was
"structured chat" was refused on a host whose preference was "terminal", and chats opened while
the setting was on were withheld from mobile once it was turned off.

The gate now asks one thing: did the client advertise agent-session.structured.v1 (in-process
callers negotiate nothing and are always admitted). Tab projection and restore follow the same
rule. With the setting no longer gating anything, the separate cleanup gate (close, cancel,
unsubscribe, release), which existed only so those kept working after the setting was switched
off, is identical to the main gate and is folded into it. The settings listener that republished
tabs when the setting changed is removed, since projection no longer depends on it.

The host setting still picks the default for launches that start on the host itself
(agent.launch from mobile, orchestration worker-start).

* fix(native-chat): the desktop declares structured chat support to paired hosts

The desktop renderer advertised agent-session.structured.v1 (and the Claude, turn-item and
background-task capabilities that go with it) to its own main process but not to a paired Orca
server. The server therefore refused every agentSession.* call from the desktop and stripped
structured chat tabs out of the tab list it published to it, so a structured chat running on a
paired server never appeared on the desktop, even though the renderer already mirrors a host's
agent-session tabs and drives each one against the server that owns its workspace.

The same renderer reads structured chats on either host, so the remote Electron list now carries
the same structured-session capabilities as the local one, and the capability test pins that
nothing is advertised only locally.

* feat(native-chat): open structured chats on the paired server that owns the workspace

With the structured-chat default on, an agent launched in a workspace that lives on a paired Orca
server always opened as a terminal (or the terminal-backed chat view). Three things kept it off
the structured path: the launch check refused every host but this machine, a remote workspace was
handed to the host-published terminal path before the structured route was even considered, and
the structured launch pipeline sent create and every follow-up call to this machine's runtime.

A workspace's owning runtime is fixed, so the pipeline now derives it from the workspace instead
of assuming this machine (structured-agent-session-owner.ts, the same derivation the chat pane
already uses to read a session). The launch intent carries that target; the pre-create support
check, create, the publication check and fence read, the launch prompt send, held option picks,
the "focus this chat" marker, the placeholder tab's host, and tab close/purge all use it.

The launch check now accepts a paired server and asks that server's own capabilities (read from
the status the client already cached for it) rather than this machine's. An SSH workspace stays
terminal-backed: no Orca runtime runs there. The host still answers createSupport before
anything is created, so an older server that refuses shows the failure in the chat tab.

A chat the user closed before its create landed is now also retired on the paired server when it
publishes, as the local sync already does. Orchestration workers placed on another runtime are
unchanged: federation creates terminal agents only.

* fix(native-chat): negotiate client-chosen launch mode so released phones and old servers keep terminals

Hosts advertise agent-session.structured.client-launch-mode.v1: they admit
structured sessions by client capability alone. A remote client that does
not advertise it (phones released before agent.launch) asks createSupport
to pick the launch mode, so the host keeps answering that with its own
setting, exactly as before. Cleanup methods keep their own named gate so a
future admission condition cannot make close or cancel refusable.

* refactor(runtime): keep the Electron client capability list in its own module

protocol-version.ts is at its line budget; the list is what the desktop
advertises to paired hosts, not the host's own contract.

* fix(native-chat): the desktop declares it picks each launch mode itself

Paired hosts and the desktop's own main process then answer createSupport
by the workspace rather than by their own chat setting.

* fix(native-chat): pin each structured chat to the host it was launched on

- Route: a paired server opens a chat only when it advertises the
  client-chosen launch mode; an older server keeps its terminal. Its
  capabilities come from the store's host status, not the compatibility
  cache that is empty after boot or reconnect.
- A launch command override is this machine's: the route applies it only
  locally, and a host's createSupport refuses on its own override.
- The owning host is resolved once, from the same value the route used,
  and carried on the launch intent, its persisted record (legacy records
  load as local), the provisional tab and every mirrored chat tab. Close,
  purge, retry and reload read it instead of re-deriving it from a
  worktree id two hosts can share; an owner that cannot be named refuses.
- Cancellation tombstones record their host: only that host's
  authoritative inventory retires one, restored cleanup closes it there,
  and a paired host's tombstone expires after 30 days if it never answers.
- A paired server's frame settles launches it published, as the local
  inventory already does for this machine.

* fix(native-chat): a paired server that declines a chat opens its terminal instead

createSupport only reads, so both of its non-answers are settled before
anything is created:
- A paired server that answers it cannot run the chat (a WSL repo, a
  Claude account mismatch, its own launch command override) closes the
  chat tab and opens the terminal the route would have chosen, with a
  notice saying why. This machine's own decline stays a failed chat.
- A host that could not be asked closes the chat tab and leaves one
  failure toast, instead of a lingering "could not confirm" chat.

* test(native-chat): a provisional chat carries its launch's host and hands pre-create failures on

* chore(native-chat): justify the two type assertions this change's lines touch

* test(native-chat): state why each staged test fixture is cast

* fix(native-chat): chats that already exist keep showing whatever the chat setting says

The structured chat setting decides only what new agents open as. With it
off, this machine's structured chats used to be hidden while the host,
which no longer reads the setting, still reported them to the workspace
activation gate, so a workspace holding only a chat opened empty. The
local chat mirror and its startup restore now run whatever the setting
says, the continue-after-restart offer follows the chats that exist, and
the setting's copy says it applies to new agents.

* fix(native-chat): the browser client keeps its host terminal on paired servers

A browser client whose own preferences turn structured chat on took the
structured route for every paired-server workspace, but its handshake
never says it reads structured sessions, so the server refused the chat
and the user got a failed chat tab where a host terminal used to open.
The route for a paired host now also asks what this client advertises to
it: the desktop's list does, the browser client's does not. Its handshake
list is now a named constant the route reads, so the two cannot drift.

The chat setting's copy now says it runs on paired Orca servers too;
WSL and SSH hosts still use terminal chat.

* fix(native-chat): a retried launch a paired server declines opens its terminal too

A launch restored after a reload settles only through its Retry, so a
declining paired server left a failed chat there while a first launch got
the server's terminal and a notice. The chat's Retry now hands the same
pre-create failures to the same replacement, carrying the prompt the
launch had staged.

* refactor(native-chat): a paired host's cancelled-chat record ends on its 30-day TTL

The paired census re-read a host's whole inventory after every
authoritative frame to retire tombstones, and a tombstone restored after
a reload needed a second such frame, so in practice it retired nothing.
A tombstone guards a random session id and is inert once stale; the chat
is already closed on its host whenever a frame shows it. The census, its
trigger in the mirror layer and its cleanup are removed; the owner-scoped
tombstones, close-on-sight, the TTL and publication marking from frames
stay.

* fix(native-chat): a chat's pane and status read from the host recorded on its tab

The chat pane and its sidebar status still derived the host from the
workspace id, which two hosts can share; a paired chat in a non-active
same-id workspace was read from this machine. Both now read the owner
stamped on the tab, as close, purge and publication already do.

* fix(native-chat): "Resume in chat" follows the terminal resume's host rule

Agent Session History offered "Resume in chat" for a conversation
recorded on this machine into a paired server's workspace, where its
transcript does not exist. A chat now resumes a conversation only on the
host that recorded it, as the terminal resume does, and that host is the
one asked whether it can resume history.

* fix(native-chat): the chat setting says older paired servers keep terminal chat

* test(native-chat): pin that a host advertises the client-chosen launch mode

* fix(native-chat): mirror this machine's chats only where it holds them

Round 1 ran the local chat mirror for everyone so existing chats show
whatever the setting says. That gave every desktop a permanent
session-tabs listener, which turns on the runtime's phone replication
paths, plus two full session-tab censuses at startup, and made the
browser client mirror its remote host a second time.

The runtime now says whether it holds structured chats: its structured
host is built only when saved chats were restored at startup or a client
created one here, and it announces the moment one is built. The mirror,
the startup restore and the continue-after-restart offer run only when
the setting launches chats or the host holds some, and never in the
browser client. A chat a paired client creates here with the setting off
still appears at once. The chat behaviour settings show wherever chats
exist, and the setting's copy says it picks what new agents open as. The
toggle-off teardown this made dead is removed.

* test(native-chat): route a paired-server launch over the capability lists both sides really advertise

* test(native-chat): record install listeners without a cast

* fix(native-chat): a paired server admits a chat before any of it exists here

The desktop opened a paired server's chat tab, launch record, queued
prompt and focus intent before asking the server, so a "no" needed a
replacement that undid and redid all of it, and every piece it missed
was a bug: the workspace deselected, the caller told "failed" while a
terminal ran its prompt, the caller's arguments and other queued prompts
lost, and a create whose reply was lost treated as never sent.

A paired launch now asks the server first and commits nothing until it
answers. Admitted opens the chat as before. Declined runs the caller's
own launch as the server's terminal, with the existing notice (a resume
fails instead, having no terminal equivalent). Unreachable opens nothing
and names the server in one toast. The new-tab launcher reports the
host's surface for paired workspaces, as it did before paired chats,
with the prompt delivery of whichever surface got the prompt. The
replacement and its error classes are gone, and the probe inside a
launch is back to its old meaning: a "no" is a failed chat with Retry,
and no answer leaves "Could not confirm" with Retry and the prompt kept,
here as on this machine.

* fix(native-chat): mirror this machine's chats only once it holds one, not once its host is built

Session history, resume preparation, terminal resume commands and replay-safe phone launches all
build the structured host for users who never had a chat, which turned on the chat mirror and the
structured-only settings rows until the next restart. The signal is now derived from the host's
records (or a records file still owed its import) and pushed when the first chat is restored or
created. A throwing listener no longer fails the install that fired it.

* fix(native-chat): a fork's reveal never seeds a terminal beside the surface the launcher opens

Forking into a paired-server workspace revealed it as if nothing would open there, so the reveal
created a blank host terminal beside the forked chat (and beside a forked agent terminal on main).
The launcher always opens the fork's surface itself, so the reveal now says so for every surface,
as the fix-checks launch already does.

* fix(native-chat): a declined direct launch keeps the caller's CLI args; an unreachable resume toasts once

When a paired server declines a "Fix checks" chat in a new workspace, the terminal that opens
instead now carries the recipe's saved CLI arguments, launch platform and launch source, as the
terminal route did. "Resume in chat" to a server that cannot be reached showed the admission's
"Could not reach" toast and the vault's generic one; the admission marks its failure notified and
the vault adds nothing.

* fix(native-chat): a declined background create opens its terminal without switching workspaces

Since #23974 a worktree create the user moved away from must not pull them onto the new
workspace. When a paired server declined that create's chat, the fallback terminal opened as a new
agent tab, whose host create selects the workspace. The create now opens its own agent terminal the
way main's background branch does: in place from the request's startup plan (so its CLI args carry),
without selecting the workspace. A create the user is still watching keeps the new-tab fallback.

* test(native-chat): name the launch's host in main's new outbox fence test

Main's new staging-failure test calls settleStructuredAgentLaunchPrompt without the target this PR
made required; it is a local launch, as in the sibling tests.

* fix(native-chat): a paired server's new chat shows no model until the server reports the one it started

A chat on a paired server starts with the server's saved model and options, but the picker showed
this desktop's saved selection (or the catalog default) until the server reported a model, and a
pick made in that window was remembered on the server under that guessed model. A paired launch
now carries no desktop seed, and until the server reports its model the picker names no model and
takes no picks. Local chats are unchanged.

* test(native-chat): seed the paired repo without a cast

The repo literal already satisfies Repo, so the changed-lines cast gate has nothing to excuse.

* feat(native-chat): createSupport reports the saved selection a new chat on this host starts with

A chat on a paired server starts with the server's saved model and options, which the desktop could
not read, so its picker showed a guess. createSupport's answer, which the desktop already waits for
before a paired launch, now also carries that seed as a new optional field (older clients ignore it).
Create and createSupport read it through one resolver so they cannot drift.

* fix(native-chat): a paired server's new chat shows the selection the server will start it with

The paired server now names its saved model and options in the admission answer the desktop
already waits for. That seed goes into the launch intent and its persisted record, so the picker
shows the server's model at once, stays pickable like a local chat, and remembers picks on the
server under that model; a reload shows the same. The locked picker remains only for a server too
old to name a seed.

Also moves host admission and launch-outcome tracking into their own modules: the latest main
merge left structured-agent-session-launch.ts over the max-lines limit.

* test(native-chat): expect the launch intent's new seed argument in exact-call assertions

* refactor(protocol): move the Electron remote client capability list into its own module

Merging main left protocol-version.ts one line over the max-lines limit on this branch. The list of
capabilities the desktop advertises to a paired host moves, unchanged, into
electron-remote-runtime-client-capabilities.ts, the module the next PR in the stack already uses
for it; importers point there.

* fix(native-chat): a paired chat with no saved server model is pickable; Retry shows the server's current seed

A server whose user never saved a chat model sends no seed, and the desktop showed a locked,
model-only picker for it, although that is the common case: no server that can admit a paired chat
predates the seed field. Such a chat now behaves like a local chat with no saved model: the CLI
default, pickable. The lock and its snapshot helper are gone.

Retry kept the first admission's seed while the create probe, which already runs on every attempt,
reported the server's current one and dropped it. The probe's seed now replaces a paired launch's
seed and the picker's, so a retried chat shows what its create will run.

* test(cross-version): stub the launch seed resolver createSupport now reads

* test(protocol): pin the desktop capability divergence against what a paired server receives

Every paired transport sends the shared remote base plus the Electron list, so the
divergence test now compares that union with the renderer's local list instead of
the declared Electron list. A capability added only to the shared base can no
longer slip past it. The two base-only capabilities it surfaced are recorded:
skills.install-result.v2 has no local caller; the authoritative-inventory label is
read by the local tabs sync but dropped by main, and is marked unsettled.

The turn-item and both background-task-stop capabilities were already sent through
the shared base, so the Electron list no longer repeats them. The wire set is
unchanged; this PR's real change on the wire is structured.v1, the Claude
structured capability and the client launch-mode capability.

* fix(native-chat): the desktop tells its own host it picks each launch mode, so retrying an existing chat works with the setting off

* docs(native-chat): name the real exit for the released-phone createSupport rule

* fix(native-chat): the route reads the capabilities a paired host actually receives

The renderer decided whether a paired host would admit a chat from the desktop's Electron list, but
every desktop transport sends that list plus the shared remote base. They agreed only because the
route's checks happened to sit in both. The route input is now built with the same
remoteRuntimeClientCapabilities the transports use (the browser client already sends its list as is),
and a test pins each against the real handshake.

* test(cross-version): a released client still gets the host-setting createSupport answer; a launch-mode client gets supported plus the seed

* test(native-chat): let main's child-records test resolve each chat's owner

Main's new test mocks worktree-runtime-owner with only the runtime environment id, but the status
projection in this PR also resolves each structured chat's owner from the worktree. The mock keeps
the module's real exports and overrides only what the test pins.

* fix(deps): take #24204's lockfile that the merge reverted

* test(native-chat): let the Codex child-approval e2e unit test resolve each chat's owner

Its worktree-runtime-owner mock exported only the runtime environment id, but this PR's status
projection also resolves each structured chat's owner from the worktree. The mock now keeps the
module's real exports and overrides only that id, as structured-child-records-switch does.

* test(native-chat): move the close-race launch cases into their own file

Merging main added launch tests on both sides and took structured-agent-session-launch.test.ts past
the 800-line limit. The three cases where a tab close races a launch move to
structured-agent-session-launch-close-race.test.ts, with the same setup the other split launch
suites copy.

* feat(cli): add --unread/--read to orca worktree set

Pass validated read/unread flags through the existing workspace metadata update.

Credit werlang for the same-directory investigation in #22838 and #22847; no source from that PR is copied.

(cherry picked from commit d9eeb028a23a66b78b08538a5ebf6052499ec24f)

* fix(opencode): fence legacy TUI viewers before creator attribution

Use the execution host's existing admission policy on the physical TUI
pane and launch token before rewriting to a session creator or mutating
the launch-token cache. Preserve live viewers, frozen server stamps and
OpenCode 2 behavior.

Add HTTP regressions for retired panes, closed tabs, replaced tokens and
relay retirement, plus current-launch, alias and compatibility controls.

Follow-up to #22838 and @werlang's original #22847; preserves the original
intentional creator attribution without copying that PR's source.

* fix(opencode): preserve current plugin exports in legacy TUI wrapper

Keep the current server, setup, id and other default export entries when
adding the legacy TUI entry. Cover their preservation and seed the ACL
fixtures with the separate installed TUI/config bytes.

This completes the current-main port of the legacy identity replacement
for issue #22838, carrying @werlang's original PR #22847 contribution.

* Skip store notifications when refreshed work items are unchanged (#24530)

An identical forced refresh previously returned an empty Zustand patch, creating a new root state and notifying every subscriber. It now returns the current state after renewing the existing freshness timestamp. Real row or metadata changes still publish once.

* Decode complete transcript lines without copying their bytes (#24546)

Decode each single owned Buffer synchronously; preserve concatenation for multipart records and remove a redundant tail array copy.

* Clear unused speech worker timers after errors and exit (#24924)

Call the existing idle timer cleanup when private current-worker state is cleared; keep current-worker guards, transcript/error order, deliberate warmth and stop deadline unchanged.

* Reuse documentation search excerpts during result navigation (#24574)

Memoize the existing pure excerpt renderer by complete raw text for the current result array, retaining original rendering as a miss fallback.

Reuse the existing timer clear block immediately after the fetch generation advances; preserve live retries and all state publications.

* Avoid rebuilding visible file paths for single-row selection (#24743)

* Reuse prepared reads while searching saved agent conversations (#24535)

Use schema-complete session columns to enable the existing bounded statement cache without caching result rows.

* Reuse discovered mobile chunks during static traversal (#24774)

Reuse the existing mounted-owner ref at the toast presentation entry while preserving all admitted extraction/screenshot and clipboard completion.

* Classify native chat waiting messages once (#24771)

Use the existing native filter traversal to populate a fresh waiting array, keeping the original predicate, policy, projection and output ordering while classifying each actual private slot once.

Guard only the existing open pruning branch when both its private selected Set and nullable anchor are empty; retain all original pre-guard projections and nonempty/anchor-only/public-helper behavior.

* Index discovered test files once during shard selection validation (#24532)

Verified selection plans previously validated each selected filename with a scan of all discovered files. One per-call Set now handles membership checks. Exact source/discovery checks, nonempty selection, fallback to all tests, shard balancing and manifests remain intact.

* test(terminal): restore the live fish fixture prerequisites (#24947)

A restored pane waits for the initial status replay before subscribing to
PTY output. This fixture never settled that replay, so fish printed its
mode-2031 arm before the renderer connected. Its PTY API also omitted the

child-stdin assertions and timeouts remain unchanged. No production change.

Read OpenCode output format from active final-argv options before -- so literal prompt arguments cannot select the JSON finalizer.

* test(terminal): restore the live fish fixture prerequisites (#24947)

A restored pane waits for the initial status replay before subscribing to
PTY output. This fixture never settled that replay, so fish printed its
mode-2031 arm before the renderer connected. Its PTY API also omitted the

* test(jcode): measure the gate against the synchronous path, not the clock

The absolute 1s bound was the flake CI shard 3/8 hit: it is tight enough to catch
a synchronous gate on an idle laptop and too tight on a loaded runner. Measuring
the same POST both ways on the same machine makes the claim a ratio, which is what
the test is actually about. Mutation-checked: a synchronous gate reads 6120ms
against a 1517ms observer.

* test(jcode): drop the wall-clock gate assertion

The bound was machine-speed sensitive and flaked on CI shard 3/8 at 1525ms. The

* fix(jcode): address CodeRabbit review on #22539

- Windows posted no payload at all: the shared builder reads `payload@-` from
  stdin, which the gate has already drained and observer hooks never receive, so
  every Windows event was dropped. Write the env var to a temp file and pipe it.
- The daemon pre-warm never fired for daemon-host spawns, which is the default
  local path; it now runs there too, and from the final env so the daemon gets the
  hook port and token.
- A failed runtime-dir mkdir took down every local terminal, jcode or not.
- removeJcodeManagedHooks matched the raw line, so a user hook whose comment
  mentioned the managed script was deleted; matching on Windows never worked.
- A managed entry left by a copied home or a platform switch is now repointed
  instead of being reported as user-owned forever.
- The OSC colour skip only checked launchAgent, so a command- or telemetry-named
  jcode pane still leaked the reply into its composer.
- `['hooks']` and a commented scalar are recognised, instead of appending a
  second [hooks] table that makes jcode reject the whole config.
- A failed tool's error is marked as tool output rather than agent prose.
- The vault keeps a session's stored name, counts its tokens, and skips
  background_task and [Scheduled task] turns.

* fix(jcode): read the journal once per turn, key prompts by byte offset

The jcode prompt reader ran a synchronous bounded file scan plus a JSON
parse on every hook event. jcode blocks on pre_tool, so a turn that ran
four tools charged the user eight scans of latency it did not need — the
prompt cannot change inside a turn.

- Cache the journal read per pane, refreshed on the turn boundary that
  can change it. The cache holds the whole evidence record, since
  hasExplicitUserPrompt needs the transcript-evidence flag and not just
  the text, and it joins the existing pane-scoped lifecycle (close,
  rename, reset) rather than living in a module singleton.
- Key a journal prompt by its absolute byte offset instead of its
  region-local line index. The backward scan windows the file from EOF,
  so appending shifted every boundary and reminted the key for a prompt
  that never moved; a repeated turn_end then slipped past the same-hash
  dedupe as a second done event with duplicate telemetry.
- Pin the platform in the daemon pre-warm tests. The pre-warm is a no-op
  off POSIX, so the dedupe and retry cases would have passed vacuously
  on a Windows runner.

* fix(jcode): quote the managed hook path, drop tools from patch prompts

Three fixes, all on paths this PR could not exercise locally.

The managed hook command was stored as a bare path. jcode tokenizes that
string shell-style before exec'ing it directly (parse_hook_command,
crates/jcode-terminal-launch/src/lib.rs): unquoted whitespace splits, and
every unquoted backslash is consumed as an escape. So on Windows
`C:\Users\me\.orca\agent-hooks\jcode-hook.cmd` reached exec as
`C:Usersme.orcaagent-hooksjcode-hook.cmd` and no hook fired at all, and a
POSIX home with a space split into two arguments. Store the path
single-quoted (verbatim, backslashes included), falling back to double
quotes for a path containing a single quote. Existing bare entries are
already repointed by the stale-key path, and getStatus accepts both forms
so the repair is not reported as a user-owned hook. The quoting helper was
previously dead code that only tests called; the three production sites
now use it. isJcodeManagedCommand also normalizes separators, since a
`/`-only needle never matched a Windows entry.

Commit-message generation feeds a staged patch to `jcode run` as the
prompt — attacker-influenced text — while jcode's default profile exposes
shell, read, write, and MCP. Pass `--tool-profile none`, which resolves to
an empty allowed-tool set in jcode's config (base_allowed_tools), matching
the read-only posture claude (plan) and codex (read-only) already take.

docs/reference/jcode-hook-events.md was never actually in this PR: the
repo ignores docs/** and tracks reference docs by allow-list only, so the
captured-payload evidence four source comments point at was silently
dropped. Allow-list it.

* test(jcode): pin the tool-profile flag in the generation plan too

The argv assertion lives in two places; --tool-profile none only landed in
one, so the plan test still expected the unrestricted argv.

Co-authored-by: czzczz <chanzrz_zbf@foxmail.com>

* fix(text-generation): refuse an oversized argv prompt on Linux too

The pre-spawn size guard only ran on Windows. Linux caps a single argv
entry at MAX_ARG_STRLEN (32 pages, 128 KiB on a 4-KiB-page host) and
execve fails with E2BIG past it, so an agent that delivers the whole
prompt as one argument — jcode, and the other argv-delivery agents —
failed on a large staged diff with an error the user could not act on.

The cap is per-argument and in bytes, which is why it is not the Windows
line budget: 40k chars trips Windows and is nowhere near the Linux limit,
so folding them together would have refused prompts Linux runs fine.

* fix(jcode): register in main's remote-installer guard, drop our duplicate

Rebasing onto 853 commits of main surfaced two things the earlier branch
had hidden.

main already owns a guard for the issue-#7253 bug class
(`remote-hook-service-registry-coverage.test.ts`). This branch had added a
second, near-identical one — a parallel implementation of a test that
already existed, which is what AGENTS.md's reuse rule is about. Deleted
ours and registered jcode in main's, which is the one that has kept pace
with every agent added since.

Also fixes a missing separator in the mobile icon map. `pnpm tc` does not
cover `mobile/`, so only the session-route closure suite caught it.

Co-authored-by: czzczz <chanzrz_zbf@foxmail.com>

* fix(jcode): decompose the four files jcode pushed over max-lines

Adding an agent tipped four modules past their line budget. AGENTS.md
forbids a `max-lines` disable or a per-file bump, so each is split on a
real seam rather than silenced:

- agent-catalog.tsx keeps `AgentIcon`, which 70+ files import, and the
  rows move out. The rows alone exceed the 300-line budget a `.ts` file
  gets, so they follow the primary/secondary split this repo already uses
  for commit-message agent specs.
- getAgentResumeArgv -> agent-resume-argv.ts, re-exported so the 18 call
  sites keep one import path.
- isDiscoverableSessionFile/pathSegments -> session-file-discovery.ts.
- remoteCodexSources -> remote-session-scanner-codex-sources.ts; Codex is
  the one remote agent with two CODEX_HOME roots.

Also:
- Records the readiness-census baseline jcode now needs. main added that
  gate while this branch was out; the fixture is the recorded 74-case
  matrix, not a hand-written one.
- Restores two entries a rebase resolution silently dropped from
  config/tsconfig.cli.json (gitlab/project-ref-parser,
  startup/shell-path-probe). Nothing to do with jcode; losing them was a
  conflict-resolution mistake on this branch.

* feat(native-chat): open structured chats on the paired Orca server that owns the workspace (#24205)

* fix(native-chat): a host admits structured sessions by client capability, not its own chat setting

A host's experimentalStructuredNativeChat decided whether any paired client could reach
agentSession.* at all, and whether session.tabs.* showed it structured tabs. That setting is the
host user's own launch preference: whether a new agent opens as a chat or a terminal is decided by
whoever launches it. Using it as admission control meant a client whose own preference was
"structured chat" was refused on a host whose preference was "terminal", and chats opened while
the setting was on were withheld from mobile once it was turned off.

The gate now asks one thing: did the client advertise agent-session.structured.v1 (in-process
callers negotiate nothing and are always admitted). Tab projection and restore follow the same
rule. With the setting no longer gating anything, the separate cleanup gate (close, cancel,
unsubscribe, release), which existed only so those kept working after the setting was switched
off, is identical to the main gate and is folded into it. The settings listener that republished
tabs when the setting changed is removed, since projection no longer depends on it.

The host setting still picks the default for launches that start on the host itself
(agent.launch from mobile, orchestration worker-start).

* fix(native-chat): the desktop declares structured chat support to paired hosts

The desktop renderer advertised agent-session.structured.v1 (and the Claude, turn-item and
background-task capabilities that go with it) to its own main process but not to a paired Orca
server. The server therefore refused every agentSession.* call from the desktop and stripped
structured chat tabs out of the tab list it published to it, so a structured chat running on a
paired server never appeared on the desktop, even though the renderer already mirrors a host's
agent-session tabs and drives each one against the server that owns its workspace.

The same renderer reads structured chats on either host, so the remote Electron list now carries
the same structured-session capabilities as the local one, and the capability test pins that
nothing is advertised only locally.

* feat(native-chat): open structured chats on the paired server that owns the workspace

With the structured-chat default on, an agent launched in a workspace that lives on a paired Orca
server always opened as a terminal (or the terminal-backed chat view). Three things kept it off
the structured path: the launch check refused every host but this machine, a remote workspace was
handed to the host-published terminal path before the structured route was even considered, and
the structured launch pipeline sent create and every follow-up call to this machine's runtime.

A workspace's owning runtime is fixed, so the pipeline now derives it from the workspace instead
of assuming this machine (structured-agent-session-owner.ts, the same derivation the chat pane
already uses to read a session). The launch intent carries that target; the pre-create support
check, create, the publication check and fence read, the launch prompt send, held option picks,
the "focus this chat" marker, the placeholder tab's host, and tab close/purge all use it.

The launch check now accepts a paired server and asks that server's own capabilities (read from
the status the client already cached for it) rather than this machine's. An SSH workspace stays
terminal-backed: no Orca runtime runs there. The host still answers createSupport before
anything is created, so an older server that refuses shows the failure in the chat tab.

A chat the user closed before its create landed is now also retired on the paired server when it
publishes, as the local sync already does. Orchestration workers placed on another runtime are
unchanged: federation creates terminal agents only.

* fix(native-chat): negotiate client-chosen launch mode so released phones and old servers keep terminals

Hosts advertise agent-session.structured.client-launch-mode.v1: they admit
structured sessions by client capability alone. A remote client that does
not advertise it (phones released before agent.launch) asks createSupport
to pick the launch mode, so the host keeps answering that with its own
setting, exactly as before. Cleanup methods keep their own named gate so a
future admission condition cannot make close or cancel refusable.

* refactor(runtime): keep the Electron client capability list in its own module

protocol-version.ts is at its line budget; the list is what the desktop
advertises to paired hosts, not the host's own contract.

* fix(native-chat): the desktop declares it picks each launch mode itself

Paired hosts and the desktop's own main process then answer createSupport
by the workspace rather than by their own chat setting.

* fix(native-chat): pin each structured chat to the host it was launched on

- Route: a paired server opens a chat only when it advertises the
  client-chosen launch mode; an older server keeps its terminal. Its
  capabilities come from the store's host status, not the compatibility
  cache that is empty after boot or reconnect.
- A launch command override is this machine's: the route applies it only
  locally, and a host's createSupport refuses on its own override.
- The owning host is resolved once, from the same value the route used,
  and carried on the launch intent, its persisted record (legacy records
  load as local), the provisional tab and every mirrored chat tab. Close,
  purge, retry and reload read it instead of re-deriving it from a
  worktree id two hosts can share; an owner that cannot be named refuses.
- Cancellation tombstones record their host: only that host's
  authoritative inventory retires one, restored cleanup closes it there,
  and a paired host's tombstone expires after 30 days if it never answers.
- A paired server's frame settles launches it published, as the local
  inventory already does for this machine.

* fix(native-chat): a paired server that declines a chat opens its terminal instead

createSupport only reads, so both of its non-answers are settled before
anything is created:
- A paired server that answers it cannot run the chat (a WSL repo, a
  Claude account mismatch, its own launch command override) closes the
  chat tab and opens the terminal the route would have chosen, with a
  notice saying why. This machine's own decline stays a failed chat.
- A host that could not be asked closes the chat tab and leaves one
  failure toast, instead of a lingering "could not confirm" chat.

* test(native-chat): a provisional chat carries its launch's host and hands pre-create failures on

* chore(native-chat): justify the two type assertions this change's lines touch

* test(native-chat): state why each staged test fixture is cast

* fix(native-chat): chats that already exist keep showing whatever the chat setting says

The structured chat setting decides only what new agents open as. With it
off, this machine's structured chats used to be hidden while the host,
which no longer reads the setting, still reported them to the workspace
activation gate, so a workspace holding only a chat opened empty. The
local chat mirror and its startup restore now run whatever the setting
says, the continue-after-restart offer follows the chats that exist, and
the setting's copy says it applies to new agents.

* fix(native-chat): the browser client keeps its host terminal on paired servers

A browser client whose own preferences turn structured chat on took the
structured route for every paired-server workspace, but its handshake
never says it reads structured sessions, so the server refused the chat
and the user got a failed chat tab where a host terminal used to open.
The route for a paired host now also asks what this client advertises to
it: the desktop's list does, the browser client's does not. Its handshake
list is now a named constant the route reads, so the two cannot drift.

The chat setting's copy now says it runs on paired Orca servers too;
WSL and SSH hosts still use terminal chat.

* fix(native-chat): a retried launch a paired server declines opens its terminal too

A launch restored after a reload settles only through its Retry, so a
declining paired server left a failed chat there while a first launch got
the server's terminal and a notice. The chat's Retry now hands the same
pre-create failures to the same replacement, carrying the prompt the
launch had staged.

* refactor(native-chat): a paired host's cancelled-chat record ends on its 30-day TTL

The paired census re-read a host's whole inventory after every
authoritative frame to retire tombstones, and a tombstone restored after
a reload needed a second such frame, so in practice it retired nothing.
A tombstone guards a random session id and is inert once stale; the chat
is already closed on its host whenever a frame shows it. The census, its
trigger in the mirror layer and its cleanup are removed; the owner-scoped
tombstones, close-on-sight, the TTL and publication marking from frames
stay.

* fix(native-chat): a chat's pane and status read from the host recorded on its tab

The chat pane and its sidebar status still derived the host from the
workspace id, which two hosts can share; a paired chat in a non-active
same-id workspace was read from this machine. Both now read the owner
stamped on the tab, as close, purge and publication already do.

* fix(native-chat): "Resume in chat" follows the terminal resume's host rule

Agent Session History offered "Resume in chat" for a conversation
recorded on this machine into a paired server's workspace, where its
transcript does not exist. A chat now resumes a conversation only on the
host that recorded it, as the terminal resume does, and that host is the
one asked whether it can resume history.

* fix(native-chat): the chat setting says older paired servers keep terminal chat

* test(native-chat): pin that a host advertises the client-chosen launch mode

* fix(native-chat): mirror this machine's chats only where it holds them

Round 1 ran the local chat mirror for everyone so existing chats show
whatever the setting says. That gave every desktop a permanent
session-tabs listener, which turns on the runtime's phone replication
paths, plus two full session-tab censuses at startup, and made the
browser client mirror its remote host a second time.

The runtime now says whether it holds structured chats: its structured
host is built only when saved chats were restored at startup or a client
created one here, and it announces the moment one is built. The mirror,
the startup restore and the continue-after-restart offer run only when
the setting launches chats or the host holds some, and never in the
browser client. A chat a paired client creates here with the setting off
still appears at once. The chat behaviour settings show wherever chats
exist, and the setting's copy says it picks what new agents open as. The
toggle-off teardown this made dead is removed.

* test(native-chat): route a paired-server launch over the capability lists both sides really advertise

* test(native-chat): record install listeners without a cast

* fix(native-chat): a paired server admits a chat before any of it exists here

The desktop opened a paired server's chat tab, launch record, queued
prompt and focus intent before asking the server, so a "no" needed a
replacement that undid and redid all of it, and every piece it missed
was a bug: the workspace deselected, the caller told "failed" while a
terminal ran its prompt, the caller's arguments and other queued prompts
lost, and a create whose reply was lost treated as never sent.

A paired launch now asks the server first and commits nothing until it
answers. Admitted opens the chat as before. Declined runs the caller's
own launch as the server's terminal, with the existing notice (a resume
fails instead, having no terminal equivalent). Unreachable opens nothing
and names the server in one toast. The new-tab launcher reports the
host's surface for paired workspaces, as it did before paired chats,
with the prompt delivery of whichever surface got the prompt. The
replacement and its error classes are gone, and the probe inside a
launch is back to its old meaning: a "no" is a failed chat with Retry,
and no answer leaves "Could not confirm" with Retry and the prompt kept,
here as on this machine.

* fix(native-chat): mirror this machine's chats only once it holds one, not once its host is built

Session history, resume preparation, terminal resume commands and replay-safe phone launches all
build the structured host for users who never had a chat, which turned on the chat mirror and the
structured-only settings rows until the next restart. The signal is now derived from the host's
records (or a records file still owed its import) and pushed when the first chat is restored or
created. A throwing listener no longer fails the install that fired it.

* fix(native-chat): a fork's reveal never seeds a terminal beside the surface the launcher opens

Forking into a paired-server workspace revealed it as if nothing would open there, so the reveal
created a blank host terminal beside the forked chat (and beside a forked agent terminal on main).
The launcher always opens the fork's surface itself, so the reveal now says so for every surface,
as the fix-checks launch already does.

* fix(native-chat): a declined direct launch keeps the caller's CLI args; an unreachable resume toasts once

When a paired server declines a "Fix checks" chat in a new workspace, the terminal that opens
instead now carries the recipe's saved CLI arguments, launch platform and launch source, as the
terminal route did. "Resume in chat" to a server that cannot be reached showed the admission's
"Could not reach" toast and the vault's generic one; the admission marks its failure notified and
the vault adds nothing.

* fix(native-chat): a declined background create opens its terminal without switching workspaces

Since #23974 a worktree create the user moved away from must not pull them onto the new
workspace. When a paired server declined that create's chat, the fallback terminal opened as a new
agent tab, whose host create selects the workspace. The create now opens its own agent terminal the
way main's background branch does: in place from the request's startup plan (so its CLI args carry),
without selecting the workspace. A create the user is still watching keeps the new-tab fallback.

* test(native-chat): name the launch's host in main's new outbox fence test

Main's new staging-failure test calls settleStructuredAgentLaunchPrompt without the target this PR
made required; it is a local launch, as in the sibling tests.

* fix(native-chat): a paired server's new chat shows no model until the server reports the one it started

A chat on a paired server starts with the server's saved model and options, but the picker showed
this desktop's saved selection (or the catalog default) until the server reported a model, and a
pick made in that window was remembered on the server under that guessed model. A paired launch
now carries no desktop seed, and until the server reports its model the picker names no model and
takes no picks. Local chats are unchanged.

* test(native-chat): seed the paired repo without a cast

The repo literal already satisfies Repo, so the changed-lines cast gate has nothing to excuse.

* feat(native-chat): createSupport reports the saved selection a new chat on this host starts with

A chat on a paired server starts with the server's saved model and options, which the desktop could
not read, so its picker showed a guess. createSupport's answer, which the desktop already waits for
before a paired launch, now also carries that seed as a new optional field (older clients ignore it).
Create and createSupport read it through one resolver so they cannot drift.

* fix(native-chat): a paired server's new chat shows the selection the server will start it with

The paired server now names its saved model and options in the admission answer the desktop
already waits for. That seed goes into the launch intent and its persisted record, so the picker
shows the server's model at once, stays pickable like a local chat, and remembers picks on the
server under that model; a reload shows the same. The locked picker remains only for a server too
old to name a seed.

Also moves host admission and launch-outcome tracking into their own modules: the latest main
merge left structured-agent-session-launch.ts over the max-lines limit.

* test(native-chat): expect the launch intent's new seed argument in exact-call assertions

* refactor(protocol): move the Electron remote client capability list into its own module

Merging main left protocol-version.ts one line over the max-lines limit on this branch. The list of
capabilities the desktop advertises to a paired host moves, unchanged, into
electron-remote-runtime-client-capabilities.ts, the module the next PR in the stack already uses
for it; importers point there.

* fix(native-chat): a paired chat with no saved server model is pickable; Retry shows the server's current seed

A server whose user never saved a chat model sends no seed, and the desktop showed a locked,
model-only picker for it, although that is the common case: no server that can admit a paired chat
predates the seed field. Such a chat now behaves like a local chat with no saved model: the CLI
default, pickable. The lock and its snapshot helper are gone.

Retry kept the first admission's seed while the create probe, which already runs on every attempt,
reported the server's current one and dropped it. The probe's seed now replaces a paired launch's
seed and the picker's, so a retried chat shows what its create will run.

* test(cross-version): stub the launch seed resolver createSupport now reads

* test(protocol): pin the desktop capability divergence against what a paired server receives

Every paired transport sends the shared remote base plus the Electron list, so the
divergence test now compares that union with the renderer's local list instead of
the declared Electron list. A capability added only to the shared base can no
longer slip past it. The two base-only capabilities it surfaced are recorded:
skills.install-result.v2 has no local caller; the authoritative-inventory label is
read by the local tabs sync but dropped by main, and is marked unsettled.

The turn-item and both background-task-stop capabilities were already sent through
the shared base, so the Electron list no longer repeats them. The wire set is
unchanged; this PR's real change on the wire is structured.v1, the Claude
structured capability and the client launch-mode capability.

* fix(native-chat): the desktop tells its own host it picks each launch mode, so retrying an existing chat works with the setting off

* docs(native-chat): name the real exit for the released-phone createSupport rule

* fix(native-chat): the route reads the capabilities a paired host actually receives

The renderer decided whether a paired host would admit a chat from the desktop's Electron list, but
every desktop transport sends that list plus the shared remote base. They agreed only because the
route's checks happened to sit in both. The route input is now built with the same
remoteRuntimeClientCapabilities the transports use (the browser client already sends its list as is),
and a test pins each against the real handshake.

* test(cross-version): a released client still gets the host-setting createSupport answer; a launch-mode client gets supported plus the seed

* test(native-chat): let main's child-records test resolve each chat's owner

Main's new test mocks worktree-runtime-owner with only the runtime environment id, but the status
projection in this PR also resolves each structured chat's owner from the worktree. The mock keeps
the module's real exports and overrides only what the test pins.

* fix(deps): take #24204's lockfile that the merge reverted

* test(native-chat): let the Codex child-approval e2e unit test resolve each chat's owner

Its worktree-runtime-owner mock exported only the runtime environment id, but this PR's status
projection also resolves each structured chat's owner from the worktree. The mock now keeps the
module's real exports and overrides only that id, as structured-child-records-switch does.

* test(native-chat): move the close-race launch cases into their own file

Merging main added launch tests on both sides and took structured-agent-session-launch.test.ts past
the 800-line limit. The three cases where a tab close races a launch move to
structured-agent-session-launch-close-race.test.ts, with the same setup the other split launch
suites copy.

* feat(cli): add --unread/--read to orca worktree set

Pass validated read/unread flags through the existing workspace metadata update.

hand-rolled curl for buildPosixAgentHookPostCommand, which also gains it the
raw-JSON transport and the --noproxy guard the bespoke copy was missing.

* test(jcode): measure the gate against the synchronous path, not the clock

The absolute 1s bound was the flake CI shard 3/8 hit: it is tight enough to catch
a synchronous gate on an idle laptop and too tight on a loaded runner. Measuring
the same POST both ways on the same machine makes the claim a ratio, which is what
the test is actually about. Mutation-checked: a synchronous gate reads 6120ms
against a 1517ms observer.

* test(jcode): drop the wall-clock gate assertion

* fix(jcode): address CodeRabbit review on #22539

- Windows posted no payload at all: the shared builder reads `payload@-` from
  stdin, which the gate has already drained and observer hooks never receive, so
  every Windows event was dropped. Write the env var to a temp file and pipe it.
- The daemon pre-warm never fired for daemon-host spawns, which is the default
  local path; it now runs there too, and from the final env so the daemon gets the
  hook port and token.
- A failed runtime-dir mkdir took down every local terminal, jcode or not.
- removeJcodeManagedHooks matched the raw line, so a user hook whose comment
  mentioned the managed script was deleted; matching on Windows never worked.
- A managed entry left by a copied home or a platform switch is now repointed
  instead of being reported as user-owned forever.
- The OSC colour skip only checked launchAgent, so a command- or telemetry-named
  jcode pane still leaked the reply into its composer.
- `['hooks']` and a commented scalar are recognised, instead of appending a
  second [hooks] table that makes jcode reject the whole config.
- A failed tool's error is marked as tool output rather than agent prose.
- The vault keeps a session's stored name, counts its tokens, and skips
  background_task and [Scheduled task] turns.

* fix(jcode): read the journal once per turn, key prompts by byte offset

The jcode prompt reader ran a synchronous bounded file scan plus a JSON
parse on every hook event. jcode blocks on pre_tool, so a turn that ran
four tools charged the user eight scans of latency it did not need — the
prompt cannot change inside a turn.

- Cache the journal read per pane, refreshed on the turn boundary that
  can change it. The cache holds the whole evidence record, since
  hasExplicitUserPrompt needs the transcript-evidence flag and not just
  the text, and it joins the existing pane-scoped lifecycle (close,
  rename, reset) rather than living in a module singleton.
- Key a journal prompt by its absolute byte offset instead of its
  region-local line index. The backward scan windows the file from EOF,
  so appending shifted every boundary and reminted the key for a prompt
  that never moved; a repeated turn_end then slipped past the same-hash
  dedupe as a second done event with duplicate telemetry.
- Pin the platform in the daemon pre-warm tests. The pre-warm is a no-op
  off POSIX, so the dedupe and retry cases would have passed vacuously
  on a Windows runner.

* fix(jcode): quote the managed hook path, drop tools from patch prompts

Three fixes, all on paths this PR could not exercise locally.

The managed hook command was stored as a bare path. jcode tokenizes that
string shell-style before exec'ing it directly (parse_hook_command,
crates/jcode-terminal-launch/src/lib.rs): unquoted whitespace splits, and
every unquoted backslash is consumed as an escape. So on Windows
`C:\Users\me\.orca\agent-hooks\jcode-hook.cmd` reached exec as
`C:Usersme.orcaagent-hooksjcode-hook.cmd` and no hook fired at all, and a
POSIX home with a space split into two arguments. Store the path
single-quoted (verbatim, backslashes included), falling back to double
quotes for a path containing a single quote. Existing bare entries are
already repointed by the stale-key path, and getStatus accepts both forms
so the repair is not reported as a user-owned hook. The quoting helper was
previously dead code that only tests called; the three production sites
now use it. isJcodeManagedCommand also normalizes separators, since a
`/`-only needle never matched a Windows entry.

Commit-message generation feeds a staged patch to `jcode run` as the
prompt — attacker-influenced text — while jcode's default profile exposes
shell, read, write, and MCP. Pass `--tool-profile none`, which resolves to
an empty allowed-tool set in jcode's config (base_allowed_tools), matching
the read-only posture claude (plan) and codex (read-only) already take.

docs/reference/jcode-hook-events.md was never actually in this PR: the
repo ignores docs/** and tracks reference docs by allow-list only, so the
captured-payload evidence four source comments point at was silently
dropped. Allow-list it.

* test(jcode): pin the tool-profile flag in the generation plan too

The argv assertion lives in two places; --tool-profile none only landed in
one, so the plan test still expected the unrestricted argv.

Co-authored-by: czzczz <chanzrz_zbf@foxmail.com>

* fix(text-generation): refuse an oversized argv prompt on Linux too

The pre-spawn size guard only ran on Windows. Linux caps a single argv
entry at MAX_ARG_STRLEN (32 pages, 128 KiB on a 4-KiB-page host) and
execve fails with E2BIG past it, so an agent that delivers the whole
prompt as one argument — jcode, and the other argv-delivery agents —
failed on a large staged diff with an error the user could not act on.

The cap is per-argument and in bytes, which is why it is not the Windows
line budget: 40k chars trips Windows and is nowhere near the Linux limit,
so folding them together would have refused prompts Linux runs fine.

* fix(jcode): register in main's remote-installer guard, drop our duplicate

Rebasing onto 853 commits of main surfaced two things the earlier branch
had hidden.

main already owns a guard for the issue-#7253 bug class
(`remote-hook-service-registry-coverage.test.ts`). This branch had added a
second, near-identical one — a parallel implementation of a test that
already existed, which is what AGENTS.md's reuse rule is about. Deleted
ours and registered jcode in main's, which is the one that has kept pace
with every agent added since.

Also fixes a missing separator in the mobile icon map. `pnpm tc` does not
cover `mobile/`, so only the session-route closure suite caught it.

* fix(jcode): decompose the four files jcode pushed over max-lines

Adding an agent tipped four modules past their line budget. AGENTS.md
forbids a `max-lines` disable or a per-file bump, so each is split on a
real seam rather than silenced:

- agent-catalog.tsx keeps `AgentIcon`, which 70+ files import, and the
  rows move out. The rows alone exceed the 300-line budget a `.ts` file
  gets, so they follow the primary/secondary split this repo already uses
  for commit-message agent specs.
- getAgentResumeArgv -> agent-resume-argv.ts, re-exported so the 18 call
  sites keep one import path.
- isDiscoverableSessionFile/pathSegments -> session-file-discovery.ts.
- remoteCodexSources -> remote-session-scanner-codex-sources.ts; Codex is
  the one remote agent with two CODEX_HOME roots.

Also:
- Records the readiness-census baseline jcode now needs. main added that
  gate while this branch was out; the fixture is the recorded 74-case
  matrix, not a hand-written one.
- Restores two entries a rebase resolution silently dropped from
  config/tsconfig.cli.json (gitlab/project-ref-parser,
  startup/shell-path-probe). Nothing to do with jcode; losing them was a
  conflict-resolution mistake on this branch.

* feat(native-chat): open structured chats on the paired Orca server that owns the workspace (#24205)

* fix(native-chat): a host admits structured sessions by client capability, not its own chat setting

A host's experimentalStructuredNativeChat decided whether any paired client could reach
agentSession.* at all, and whether session.tabs.* showed it structured tabs. That setting is the
host user's own launch preference: whether a new agent opens as a chat or a terminal is decided by
whoever launches it. Using it as admission control meant a client whose own preference was
"structured chat" was refused on a host whose preference was "terminal", and chats opened while
the setting was on were withheld from mobile once it was turned off.

The gate now asks one thing: did the client advertise agent-session.structured.v1 (in-process
callers negotiate nothing and are always admitted). Tab projection and restore follow the same
rule. With the setting no longer gating anything, the separate cleanup gate (close, cancel,
unsubscribe, release), which existed only so those kept working after the setting was switched
off, is identical to the main gate and is folded into it. The settings listener that republished
tabs when the setting changed is removed, since projection no longer depends on it.

The host setting still picks the default for launches that start on the host itself
(agent.launch from mobile, orchestration worker-start).

* fix(native-chat): the desktop declares structured chat support to paired hosts

The desktop renderer advertised agent-session.structured.v1 (and the Claude, turn-item and
background-task capabilities that go with it) to its own main process but not to a paired Orca
server. The server therefore refused every agentSession.* call from the desktop and stripped
structured chat tabs out of the tab list it published to it, so a structured chat running on a
paired server never appeared on the desktop, even though the renderer already mirrors a host's
agent-session tabs and drives each one against the server that owns its workspace.

The same renderer reads structured chats on either host, so the remote Electron list now carries
the same structured-session capabilities as the local one, and the capability test pins that
nothing is advertised only locally.

* feat(native-chat): open structured chats on the paired server that owns the workspace

With the structured-chat default on, an agent launched in a workspace that lives on a paired Orca
server always opened as a terminal (or the terminal-backed chat view). Three things kept it off
the structured path: the launch check refused every host but this machine, a remote workspace was
handed to the host-published terminal path before the structured route was even considered, and
the structured launch pipeline sent create and every follow-up call to this machine's runtime.

A workspace's owning runtime is fixed, so the pipeline now derives it from the workspace instead
of assuming this machine (structured-agent-session-owner.ts, the same derivation the chat pane
already uses to read a session). The launch intent carries that target; the pre-create support
check, create, the publication check and fence read, the launch prompt send, held option picks,
the "focus this chat" marker, the placeholder tab's host, and tab close/purge all use it.

The launch check now accepts a paired server and asks that server's own capabilities (read from
the status the client already cached for it) rather than this machine's. An SSH workspace stays
terminal-backed: no Orca runtime runs there. The host still answers createSupport before
anything is created, so an older server that refuses shows the failure in the chat tab.

A chat the user closed before its create landed is now also retired on the paired server when it
publishes, as the local sync already does. Orchestration workers placed on another runtime are
unchanged: federation creates terminal agents only.

* fix(native-chat): negotiate client-chosen launch mode so released phones and old servers keep terminals

Hosts advertise agent-session.structured.client-launch-mode.v1: they admit
structured sessions by client capability alone. A remote client that does
not advertise it (phones released before agent.launch) asks createSupport
to pick the launch mode, so the host keeps answering that with its own
setting, exactly as before. Cleanup methods keep their own named gate so a
future admission condition cannot make close or cancel refusable.

* refactor(runtime): keep the Electron client capability list in its own module

protocol-version.ts is at its line budget; the list is what the desktop
advertises to paired hosts, not the host's own contract.

* fix(native-chat): the desktop declares it picks each launch mode itself

Paired hosts and the desktop's own main process then answer createSupport
by the workspace rather than by their own chat setting.

* fix(native-chat): pin each structured chat to the host it was launched on

- Route: a paired server opens a chat only when it advertises the
  client-chosen launch mode; an older server keeps its terminal. Its
  capabilities come from the store's host status, not the compatibility
  cache that is empty after boot or reconnect.
- A launch command override is this machine's: the route applies it only
  locally, and a host's createSupport refuses on its own override.
- The owning host is resolved once, from the same value the route used,
  and carried on the launch intent, its persisted record (legacy records
  load as local), the provisional tab and every mirrored chat tab. Close,
  purge, retry and reload read it instead of re-deriving it from a
  worktree id two hosts can share; an owner that cannot be named refuses.
- Cancellation tombstones record their host: only that host's
  authoritative inventory retires one, restored cleanup closes it there,
  and a paired host's tombstone expires after 30 days if it never answers.
- A paired server's frame settles launches it published, as the local
  inventory already does for this machine.

* fix(native-chat): a paired server that declines a chat opens its terminal instead

createSupport only reads, so both of its non-answers are settled before
anything is created:
- A paired server that answers it cannot run the chat (a WSL repo, a
  Claude account mismatch, its own launch command override) closes the
  chat tab and opens the terminal the route would have chosen, with a
  notice saying why. This machine's own decline stays a failed chat.
- A host that could not be asked closes the chat tab and leaves one
  failure toast, instead of a lingering "could not confirm" chat.

* test(native-chat): a provisional chat carries its launch's host and hands pre-create failures on

* chore(native-chat): justify the two type assertions this change's lines touch

* test(native-chat): state why each staged test fixture is cast

* fix(native-chat): chats that already exist keep showing whatever the chat setting says

The structured chat setting decides only what new agents open as. With it
off, this machine's structured chats used to be hidden while the host,
which no longer reads the setting, still reported them to the workspace
activation gate, so a workspace holding only a chat opened empty. The
local chat mirror and its startup restore now run whatever the setting
says, the continue-after-restart offer follows the chats that exist, and
the setting's copy says it applies to new agents.

* fix(native-chat): the browser client keeps its host terminal on paired servers

A browser client whose own preferences turn structured chat on took the
structured route for every paired-server workspace, but its handshake
never says it reads structured sessions, so the server refused the chat
and the user got a failed chat tab where a host terminal used to open.
The route for a paired host now also asks what this client advertises to
it: the desktop's list does, the browser client's does not. Its handshake
list is now a named constant the route reads, so the two cannot drift.

The chat setting's copy now says it runs on paired Orca servers too;
WSL and SSH hosts still use terminal chat.

* fix(native-chat): a retried launch a paired server declines opens its terminal too

A launch restored after a reload settles only through its Retry, so a
declining paired server left a failed chat there while a first launch got
the server's terminal and a notice. The chat's Retry now hands the same
pre-create failures to the same replacement, carrying the prompt the
launch had staged.

* refactor(native-chat): a paired host's cancelled-chat record ends on its 30-day TTL

The paired census re-read a host's whole inventory after every
authoritative frame to retire tombstones, and a tombstone restored after
a reload needed a second such frame, so in practice it retired nothing.
A tombstone guards a random session id and is inert once stale; the chat
is already closed on its host whenever a frame shows it. The census, its
trigger in the mirror layer and its cleanup are removed; the owner-scoped
tombstones, close-on-sight, the TTL and publication marking from frames
stay.

* fix(native-chat): a chat's pane and status read from the host recorded on its tab

The chat pane and its sidebar status still derived the host from the
workspace id, which two hosts can share; a paired chat in a non-active
same-id workspace was read from this machine. Both now read the owner
stamped on the tab, as close, purge and publication already do.

* fix(native-chat): "Resume in chat" follows the terminal resume's host rule

Agent Session History offered "Resume in chat" for a conversation
recorded on this machine into a paired server's workspace, where its
transcript does not exist. A chat now resumes a conversation only on the
host that recorded it, as the terminal resume does, and that host is the
one asked whether it can resume history.

* fix(native-chat): the chat setting says older paired servers keep terminal chat

* test(native-chat): pin that a host advertises the client-chosen launch mode

* fix(native-chat): mirror this machine's chats only where it holds them

Round 1 ran the local chat mirror for everyone so existing chats show
whatever the setting says. That gave every desktop a permanent
session-tabs listener, which turns on the runtime's phone replication
paths, plus two full session-tab censuses at startup, and made the
browser client mirror its remote host a second time.

The runtime now says whether it holds structured chats: its structured
host is built only when saved chats were restored at startup or a client
created one here, and it announces the moment one is built. The mirror,
the startup restore and the continue-after-restart offer run only when
the setting launches chats or the host holds some, and never in the
browser client. A chat a paired client creates here with the setting off
still appears at once. The chat behaviour settings show wherever chats
exist, and the setting's copy says it picks what new agents open as. The
toggle-off teardown this made dead is removed.

* test(native-chat): route a paired-server launch over the capability lists both sides really advertise

* test(native-chat): record install listeners without a cast

* fix(native-chat): a paired server admits a chat before any of it exists here

The desktop opened a paired server's chat tab, launch record, queued
prompt and focus intent before asking the server, so a "no" needed a
replacement that undid and redid all of it, and every piece it missed
was a bug: the workspace deselected, the caller told "failed" while a
terminal ran its prompt, the caller's arguments and other queued prompts
lost, and a create whose reply was lost treated as never sent.

A paired launch now asks the server first and commits nothing until it
answers. Admitted opens the chat as before. Declined runs the caller's
own launch as the server's terminal, with the existing notice (a resume
fails instead, having no terminal equivalent). Unreachable opens nothing
and names the server in one toast. The new-tab launcher reports the
host's surface for paired workspaces, as it did before paired chats,
with the prompt delivery of whichever surface got the prompt. The
replacement and its error classes are gone, and the probe inside a
launch is back to its old meaning: a "no" is a failed chat with Retry,
and no answer leaves "Could not confirm" with Retry and the prompt kept,
here as on this machine.

* fix(native-chat): mirror this machine's chats only once it holds one, not once its host is built

Session history, resume preparation, terminal resume commands and replay-safe phone launches all
build the structured host for users who never had a chat, which turned on the chat mirror and the
structured-only settings rows until the next restart. The signal is now derived from the host's
records (or a records file still owed its import) and pushed when the first chat is restored or
created. A throwing listener no longer fails the install that fired it.

* fix(native-chat): a fork's reveal never seeds a terminal beside the surface the launcher opens

Forking into a paired-server workspace revealed it as if nothing would open there, so the reveal
created a blank host terminal beside the forked chat (and beside a forked agent terminal on main).
The launcher always opens the fork's surface itself, so the reveal now says so for every surface,
as the fix-checks launch already does.

* fix(native-chat): a declined direct launch keeps the caller's CLI args; an unreachable resume toasts once

When a paired server declines a "Fix checks" chat in a new workspace, the terminal that opens
instead now carries the recipe's saved CLI arguments, launch platform and launch source, as the
terminal route did. "Resume in chat" to a server that cannot be reached showed the admission's
"Could not reach" toast and the vault's generic one; the admission marks its failure notified and
the vault adds nothing.

* fix(native-chat): a declined background create opens its terminal without switching workspaces

Since #23974 a worktree create the user moved away from must not pull them onto the new
workspace. When a paired server declined that create's chat, the fallback terminal opened as a new
agent tab, whose host create selects the workspace. The create now opens its own agent terminal the
way main's background branch does: in place from the request's startup plan (so its CLI args carry),
without selecting the workspace. A create the user is still watching keeps the new-tab fallback.

* test(native-chat): name the launch's host in main's new outbox fence test

Main's new staging-failure test calls settleStructuredAgentLaunchPrompt without the target this PR
made required; it is a local launch, as in the sibling tests.

* fix(native-chat): a paired server's new chat shows no model until the server reports the one it started

A chat on a paired server starts with the server's saved model and options, but the picker showed
this desktop's saved selection (or the catalog default) until the server reported a model, and a
pick made in that window was remembered on the server under that guessed model. A paired launch
now carries no desktop seed, and until the server reports its model the picker names no model and
takes no picks. Local chats are unchanged.

* test(native-chat): seed the paired repo without a cast

The repo literal already satisfies Repo, so the changed-lines cast gate has nothing to excuse.

* feat(native-chat): createSupport reports the saved selection a new chat on this host starts with

A chat on a paired server starts with the server's saved model and options, which the desktop could
not read, so its picker showed a guess. createSupport's answer, which the desktop already waits for
before a paired launch, now also carries that seed as a new optional field (older clients ignore it).
Create and createSupport read it through one resolver so they cannot drift.

* fix(native-chat): a paired server's new chat shows the selection the server will start it with

The paired server now names its saved model and options in the admission answer the desktop
already waits for. That seed goes into the launch intent and its persisted record, so the picker
shows the server's model at once, stays pickable like a local chat, and remembers picks on the
server under that model; a reload shows the same. The locked picker remains only for a server too
old to name a seed.

Also moves host admission and launch-outcome tracking into their own modules: the latest main
merge left structured-agent-session-launch.ts over the max-lines limit.

* test(native-chat): expect the launch intent's new seed argument in exact-call assertions

* refactor(protocol): move the Electron remote client capability list into its own module

Merging main left protocol-version.ts one line over the max-lines limit on this branch. The list of
capabilities the desktop advertises to a paired host moves, unchanged, into
electron-remote-runtime-client-capabilities.ts, the module the next PR in the stack already uses
for it; importers point there.

* fix(native-chat): a paired chat with no saved server model is pickable; Retry shows the server's current seed

A server whose user never saved a chat model sends no seed, and the desktop showed a locked,
model-only picker for it, although that is the common case: no server that can admit a paired chat
predates the seed field. Such a chat now behaves like a local chat with no saved model: the CLI
default, pickable. The lock and its snapshot helper are gone.

Retry kept the first admission's seed while the create probe, which already runs on every attempt,
reported the server's current one and dropped it. The probe's seed now replaces a paired launch's
seed and the picker's, so a retried chat shows what its create will run.

* test(cross-version): stub the launch seed resolver createSupport now reads

* test(protocol): pin the desktop capability divergence against what a paired server receives

Every paired transport sends the shared remote base plus the Electron list, so the
divergence test now compares that union with the renderer's local list instead of
the declared Electron list. A capability added only to the shared base can no
longer slip past it. The two base-only capabilities it surfaced are recorded:
skills.install-result.v2 has no local caller; the authoritative-inventory label is
read by the local tabs sync but dropped by main, and is marked unsettled.

The turn-item and both background-task-stop capabilities were already sent through
the shared base, so the Electron list no longer repeats them. The wire set is
unchanged; this PR's real change on the wire is structured.v1, the Claude
structured capability and the client launch-mode capability.

* fix(native-chat): the desktop tells its own host it picks each launch mode, so retrying an existing chat works with the setting off

* docs(native-chat): name the real exit for the released-phone createSupport rule

* fix(native-chat): the route reads the capabilities a paired host actually receives

The renderer decided whether a paired host would admit a chat from the desktop's Electron list, but
every desktop transport sends that list plus the shared remote base. They agreed only because the
route's checks happened to sit in both. The route input is now built with the same
remoteRuntimeClientCapabilities the transports use (the browser client already sends its list as is),
and a test pins each against the real handshake.

* fix(source-control): default Codex to GPT-5.6 Terra low (#24495)

* fix(source-control): use Codex's configured model by default

Source Control AI pinned Codex to gpt-5.5, which Codex retires on
2026-10-14. Any path that still resolves to that slug would then break
commit-message and PR-field generation.

Follow the Antigravity precedent (#21606): add a "Config default" entry
for Codex, make it the default, and omit --model when it is selected so
`codex exec` uses the model from the user's Codex config or Codex's own
default. Explicit model choices still pass --model.

Older remote servers would still build `--model default`, so advertise
git.codex-configured-model.v1 and have clients refuse the sentinel for
servers without it, the same way Antigravity is gated. The gate now
covers both agents, and the two capabilities live in their own module
because protocol-version.ts is at the max-lines limit.

Written with AI assistance (Claude Code).

Fixes #24481

* fix(source-control): honor -m, repo overrides and low effort for Codex

Review on #24495 found three gaps in the configured-model change.
The remote compatibility gate only recognized --model, so a recipe
passing Codex's -m short flag was rejected on older servers. The gate
also ignored the repository's per-operation model override that the
server applies. And moving Codex to Config default dropped the low
reasoning effort the pinned model used, which would change cost and
latency for users whose Codex config sets a higher effort.

* fix(source-control): match gate repo and model checks to the server

Repo ids can repeat across hosts, so the configured-model gate now reads
the repo row for the worktree's host instead of the first id match, the
same row the server applies. A recipe passing --model default or
-m default no longer counts as an explicit model, since an older server
still forwards that sentinel to the Codex CLI.

* fix(source-control): read only the worktree host's repo row in the gate

A worktree that names its own host must not fall back to the runtime
host's repo row, since the server applies the row for the worktree's
host. Also cover an environment id that needs URL encoding.

* fix(jira): search plain text when task search input isn't JQL (#22900)

* fix(jira): search plain text when task search input isn't JQL

The Tasks page sent every keystroke to Jira as JQL, so partial input like `s` failed with a 400.

Fixes #22265

* fix(jira): keep the JQL rejection reason behind Details

For plain-text searches the reason ("Field 'login' does not exist") reads as noise.

* fix(jira): announce the text-match notice to screen readers

* fix(jira): skip the wildcard when the last search word has punctuation

Jira doesn't split a wildcard term into words, so `login,*` or `c#*` matched nothing.

* fix(jira): keep the text-match live region mounted between searches

* fix(jira): keep hyphenated words like sign-in as plain text search

* fix(jira): retry a key-shaped search as text when no issue matches

Input like `utf-8`, `sha-256` or `covid-19` matches the issue-key shape, so
the search ran only `key = "UTF-8"` and showed an empty list with nothing to
explain why. An empty exact-key lookup is a wrong guess, not an answer, so
retry it as a text search — the same let-Jira-decide-then-fall-back rule the
JQL path already uses.

Splits the key and text builders apart so the caller can tell which branch it
took; `buildJiraTextSearchJql` keeps its combined behaviour for the
smart-workspace caller.

* fix(jira): let Jira's answer settle key, JQL and text guesses

Bare `in`/`is` sent everyday phrases down the JQL path, a key lookup Jira
answered with 400 never reached the text search, and a missing key like
PROJ-1401 was read as a lost connection. One key-or-text search now serves
the Tasks page and new-workspace, and one parser reads the status prefix.

* fix(jira): require IN to be its own word before a function name

`input (raw)` and `init()` read as `in` + a function call and took the JQL path.

* fix(runtime): report an open agent question as blocked to tui-idle waits (#24533)

OpenCode's question tool (and Pi/OMP ask tools and custom modals) put the
hook row in a waiting state but paint no dialog wording the blocked-text
layer knows, so the hook lane read the wait as pending and the tui-idle
wait timed out with no blocked reason. For agents whose hooks are
authoritative, a wait the hook reports with no recognised dialog text now
blocks with the existing agent-interactive-prompt reason, unless input
reached the pane after the row (it may have answered the question before
the next hook arrived).

* fix(runtime): read Codex's 'Implement this plan?' menu as blocked (#24536)

After a Plan-mode turn Codex shows a menu that owns the keyboard, but its Stop
hook has already fired, so a tui-idle wait settled ready and sent text into the
menu. A Codex blocked text anchor now names it an interactive prompt while its
key row ends the tail, written against a new 0.160.0 capture that is replayed
by the readiness census.

* feat: live updates for agent state rules (#24387)

Orca downloads a newer agent-state-rules.json from a fixed GitHub release (stable or next channel), validates it like the bundled rules, and applies it without a restart; a local override wins over the download, which wins over the bundled rules. A hand-started workflow from main is the only publisher; merging publishes nothing.

* fix(runtime): settle Codex tui-idle waits on its hook done, leaving working rows to the rules (#24541)

A headless orca serve has no window to write the Codex ready title, so a
Codex tui-idle wait settled only after three quiet seconds. Rule files gain
profile.hooks: "turn-end": a fresh hook done settles the wait, while a
working or permission row leaves the decision to the rules, so a Codex
whose Esc posts no event (before its Interrupt hook) cannot hang the wait.
Codex moves from identity-only to turn-end.

* feat(terminal): point an old terminal's shared-server banner at a new terminal

A terminal opened before the update that added Orca's codex wrapper is
still served by an older terminal daemon, so a typed codex there joins
Codex's shared server. The banner now says why and offers a new terminal
instead of the global Fix, which changes Codex settings and stops a
server other sessions use.

Detection reads the owning daemon's protocol from the router's in-memory
session map, only after a pane is already found on the shared server.

Refs #24217, STA-9051

* refactor(terminal): simplify the old-terminal banner after review

- Open new terminal now works from Activity, which shows panes from
  worktrees that are not active: it activates the tab's worktree first.
- Inline the legacy-daemon check in the IPC handler over the existing
  getLegacyDaemonAdapters instead of a new routing export.
- One banner frame with the variant chosen inline; the Fix dialog is a
  sibling rather than a children slot.
- Rename CodexSharedServerJoin to CodexSharedServerStatus.

* fix(terminal): open the new terminal in the pane's own workspace, and only promise it where it helps

Open new terminal now always goes through the folder-aware workspace activation
(returning early when that fails) and reveals the floating panel for floating
panes, so folder workspaces and panes viewed from Activity open in the right place.

The old-terminal variant now shows only when the shell Codex was typed into gets
Orca's codex function from this build: zsh, bash and PowerShell from protocol 37,
fish from 39, cmd.exe never. The shell is the parent of the Codex process in the
process table the shared-server check already reads.

* feat(terminal): explain an old terminal's shared server in Learn more

Old-tab banner says Orca now gives each Codex its own server, and gains a
Learn more dialog: why it matters, why this terminal still shares, Open new
terminal, and a quieter way into the existing Turn off / Stop server steps.

* fix(terminal): shorten the old-terminal Learn more copy to one line

* fix(terminal): drop the global fix from the old-terminal dialog

A new terminal already runs Codex on its own server there, so turning off sharing everywhere only changes settings outside Orca and can end other sessions.

* fix(terminal): treat fish without config as a shell Orca does not wrap

* fix(terminal): return focus when a Codex shared-server dialog closes

Both banner dialogs are controlled with no Radix trigger, so Esc or X left
focus on document.body. Capture the active surface when the banner opens a
dialog and restore it on close via useModalReturnFocus; Open new terminal
skips the restore so the new terminal keeps focus.

* fix(filesystem): deleting a workspace no longer fails as 'outside allowed directories' in WSL-runtime C:\ projects (#24242)

* fix(filesystem): list a WSL-runtime repo's worktrees through its distro when authorizing paths

* fix(filesystem): record the Git that listed each repo's roots and keep WSL roots under repair

- Registration now takes the distro the caller listed through (create and catalog scan pass theirs)
  instead of re-resolving the runtime, so a stale-routed listing is relisted on the next miss.
- A runtime awaiting repair no longer counts as a routing change, so its last WSL listing stays
  authorized instead of being replaced by a host-Git listing.
- The routing check runs after each awaited refresh, so a runtime switch during an in-flight
  rebuild is corrected in the same request.
- Reuse the shared distro helper for listing; move the drift check into the relist policy and
  refresh the root set once per batch.

* test(worktrees): fail the host-Git scan registration test when nothing registers

* fix: dismiss Codex account prompt and return focus to terminal (#24683)

* chore(worktree): include create timing and spare outcome in the workspace create events (#24483)

* chore(worktree): include create timing and spare outcome in the workspace-created event

The workspace_created and workspace_create_failed events gain optional,
numbers-and-enums-only fields built from what the create already measured:
total and per-phase durations, the prepared-checkout hit/miss and miss
reason, the execution host (local/WSL/SSH), a worktree count bucket, how
many other creates were in flight, whether the repo has a post-checkout
hook (file existence only, probed after the create returns), and for a
failure the phase it died in plus elapsed time. No new git process runs;
consent and opt-out are unchanged.

* fix(worktree): attribute failed_phase by error, label WSL-path repos, skip the hook check with telemetry off

- failed_phase now names the outermost timed step the thrown error (or its cause) left, so a
  caught failure or a concurrent sibling step can no longer be misattributed; the old-relay SSH
  error keeps its cause so it still reads as git_worktree_add.
- execution_host follows the same rule Git routing uses, so a \\wsl.localhost repo reads wsl.
- The post-checkout hook check does not read the repo when telemetry is disabled.
- Privacy page mentions the miss reason code and the failed step.

* test(worktree): pin the old-relay SSH add error to git_worktree_add through its cause

* fix(worktree): name the create event field sets for their role, and type the old-relay test's caught error

* fix(worktree): send create events from runtime creates and record what the spare checkout did

Runtime creates (CLI, agents, phone app, paired clients, orchestration, server
automations) reuse prepared checkouts like the app's own creates, but recorded
no timing and sent no events. Both entry points now start one shared sender
(workspace-create-telemetry.ts), so every create sends exactly one event with
the same fields, plus create_entry_point (app | runtime).

Spare-checkout fields:
- concurrent_preparations: peak prepared-checkout builds and background
  discards running during the create, excluding the one it used; the window
  closes before the create's own re-arm starts.
- prepared_checkout_claim / prepared_checkout_discard phases, so on a miss
  git_worktree_add minus the prepared_checkout_* phases is the plain checkout.
- prepared_checkout_reset (none | base_moved | retargeted) replaces the
  retargeted flag; prepared_checkout_origin (prefetch | rearm) on hits.
- workspace_create_failed carries the spare outcome and its wait.
- repo_index_size_bucket from one stat of .git/index in the existing
  post-create probe (telemetry on, local/WSL only, 2 s cap).

* fix(worktree): add spare build and idle time, the re-arm prefetch origin, and a tracked-file count

- prepared_checkout_build_ms / prepared_checkout_idle_ms on hits: from arming
  the spare to ready, and how long it sat ready before the claim (0 when the
  create waited). readyAt is recorded in the pool's existing ready handler.
- prepared_checkout_origin gains rearm_then_prefetch: an automatic re-arm that
  the dialog prefetch then asked for too, so rearm means the re-arm alone.
- repo_file_count_bucket replaces the index byte size: the entry count from
  the 12-byte index header, which is the same in every index version; left
  out for a split or sparse index.
- The shared sender never lets a failed send change the create's result or
  error; it logs instead and still ends the create's concurrency membership.
- Tests pin the runtime SSH create's timing hand-off and the throwing-send
  cases on both entry points.

* fix(worktree): leave out the file count under any sparse checkout and time spare builds monotonically

- The repo probe also reads .git/config.worktree, where git sparse-checkout
  --sparse-index writes index.sparse, and omits the file count whenever
  sparse checkout or a sparse index is on in either file, with Git's boolean
  spellings. core.hooksPath there is honoured too.
- prepared_checkout_build_ms / _idle_ms use performance.now(), like every
  other duration; the build is timed from its own start (buildStartedAt).
- The origin field comment names all three values.

* fix(worktree): keep the spare's build time on its first build and count worktrees by lock reason

- prepared_checkout_build_ms runs from the first build's start (including any
  wait for the base fetch it is built on) to its first ready; a later tip
  refresh no longer restarts it, though it still counts as new preparation
  work. prepared_checkout_idle_ms runs from the latest ready (build or
  refresh) to the claim.
- The worktree count reads each .git/worktrees entry's locked file and leaves
  out entries whose lock reason names an Orca preparation, the way the
  listing does, instead of subtracting this process's spares. That covers
  spares from other processes, crash leftovers and spares being discarded,
  and cannot run one low while a spare's admin dir does not exist yet. It has
  its own 1.5 s cap inside the probe.

* ci(release): skip the orcad template for tags that predate it (#24872)

A patch cut from a base older than #24155 has no orcad template source, so
the template job could never pass and every desktop build waited on it.

* fix(runtime): make OMP 18.4 workers ready at the composer and keep stale-title clears display-only (#24295)

* fix(runtime): require OMP composer readiness and retain native title evidence

Keep timer-cleared titles in display state so they cannot settle an idle wait.
Require OMP's captured empty composer through the existing screen rules.

* fix(runtime): veto OMP setup by screen and keep stale-title clears display-only

OMP readiness no longer keys on the composer's thinking-effort hint, which
OMP retires after a few uses, hides once a conversation exists and renders
differently per glyph preset. Instead OMP's setup wizard (alternate screen or
a "Setup step N of M" heading) vetoes every ready lane, and OMP's own `π >`
idle title counts for the omp identity only once quiet on a screen read clear
of the wizard. Other OMP titles take the general path again, so the
post-turn `π -` title, 17.x `π:` titles and first-party blocked waits behave
as before. `π >` is no longer explicit idle for every identity.

The stale-working-title clear stays out of runtime records, but display
readers (worktree ps, phone status and titles, terminal list, orchestration
pointer, orphan adoption and reveal titles) now project records through one
display accessor, so they show the cleared title and status again. A title
the clear retired can no longer prove an agent is present; the foreground
process must, which also covers the retained Cursor spinner, so the Cursor
presence exclusion is reverted.

* test(runtime): refuse OMP's setup splash, which has no step heading

* test(runtime): a genuine title retires the stale-working display clear

* test(daemon): record the OMP captures' inherited shrink cursor divergence

* fix(runtime): settle OMP's idle title by its age and veto only its alternate screen

OMP 18.4 re-asserts bracketed paste every second once a terminal answers
its capability probe, which Orca's terminals do, so an idle OMP pane never
went quiet and worker-start still timed out. Its idle title now counts once
it has stood a quiescence window on a screen read clear of the setup wizard.
The setup veto now reads only the alternate screen: the wizard always runs
there, and a 'Setup step N of M' line on the normal screen is an answer's
own text.

* test(runtime): let the grid ingest OMP repaints before the title arrives

* fix(runtime): keep the stale-title clear's process checks and record lifetime

The stale-working-title clear is now an explicit branch instead of an early
return. It still skips the title/status evidence readiness and delivery
read, but runs what main's clear did to re-derive process state: the
foreground-agent re-probe (an exited shell-launched agent loses its
identity) and the completion-race exit check behind a fresh done hook. The
clear now lives on the PTY record, so an SSH relay drop and reattach keeps
the cleared display, and a recreated tracker is seeded from it. Presence
judges a retired title by display ordering, so a renderer pane title older
than the clear cannot prove an exited agent is present.

* docs(runtime): OMP's idle title precedes its setup wizard by its startup tail

* fix(runtime): judge agent presence by the displayed title while a clear stands

A title the stale-working timer cleared used to veto presence outright, so a
live, busy agent whose title cleared to its name and whose process Orca
cannot recognize read as no agent, and the answer depended on whether a
renderer pane was mounted. Presence and the terminal status query now read
the display projection instead, which is what they read before the clear
stopped rewriting records: a cwd spinner still clears to a neutral title, so
the foreground process decides for an agent that exited behind it.

* fix(runtime): compare a cleared title with a lifecycle cleared the same way

The stale-working clear no longer writes the prompt lifecycle, so the
blocked-dialog check compared a cleared title with a still-working
lifecycle and ignored a trust or update dialog painted after the clear:
terminal status said idle, the guarded send accepted, and a mounted pane's
interactive wait went missing. The lifecycle is now projected through the
clear wherever a cleared title is compared with it, as main recorded both
together. That comparison can only report a wait on the user, never idle.

* fix(runtime): verify prompts behind a stale-title clear against main's baseline

Prompt-submission verification read the native lifecycle while a
stale-working clear stood, so output after a swallowed Enter behind a stuck
spinner counted as delivered, and the first spinner frame after the clear
was not a new turn. Its starting status now goes through the same lifecycle
projection the blocked-dialog check uses, and the first working status
after a clear starts a new turn, as main recorded it. Readiness, delivery
and the mailbox still read only native evidence. The blocked-dialog comment
now says the projected pair reproduces main's verdict.

* fix(opencode-go): don't fall back to OPENCODE_API_KEY when the credential database is unreadable (#24605)

* fix(opencode-go): stop before OPENCODE_API_KEY when the credential database is unreadable

An unreadable OpenCode credential database read as 'no key', so the Go key
resolver fell through to OPENCODE_API_KEY, which OpenCode shares with its
Zen provider and can show usage for the wrong key. The database read now
reports unreadable separately; with an env key set the resolver stops, and
the usage fetch uses a configured cookie or shows a readable error.

* fix(codex): skip the hook trust RPC when Codex's session index is unreadable (#24604)

tri-state pending check lets the trust grant take its fallback, while other
callers keep their existing boolean behaviour.

* refactor(cursor): move the desktop-login read onto the shared foreign SQLite reader worker (#24603)

* refactor(sqlite): rename the OpenCode SQLite worker entry to foreign-sqlite-reader (STA-9122)

The worker thread that reads OpenCode's database off the main thread is about
to read other apps' databases too, so its entry is renamed to what it is:
src/main/foreign-sqlite-readers/foreign-sqlite-reader-entry.ts, built as
out/main/foreign-sqlite-reader-entry.js.

Why now: #24572 fixed the Cursor focus freeze with a second, dedicated
worker. Rather than grow one worker per foreign app, the next commit moves
Cursor onto this entry and deletes that worker. This commit is the rename
only; #24572's cursor-desktop-profile-worker-entry lines stay until then.

It moves out of ai-vault/ into a new foreign-sqlite-readers/ module because
it will no longer be session-scanner code; the module will own the readers,
their dispatch, protocol and main-process client.

The entry still routes only OpenCode kinds in this commit. The OpenCode
dispatch, protocol and process entry stay in ai-vault/ and stay OpenCode-only,
because the SSH/WSL relay reader bundles them (build-relay.mjs).

Every reference is updated: electron.vite.config.ts input key, knip entry,
the plain-node entry guard and its test, the asarUnpack list (the scanner
service still spawns this entry under ELECTRON_RUN_AS_NODE), and the
electron-builder test that reads the filename. The filename and the
beside-or-one-up (Rollup chunks) lookup now live in
foreign-sqlite-reader-entry-path.ts, which the OpenCode spawn reuses, plus an
Electron-main resolver that uses the packaged app.asar path.

* fix(cursor): move the desktop-login read from its dedicated worker onto the foreign SQLite reader (STA-9122)

#24572 fixed the Cursor focus freeze (#24360) with a dedicated worker
(rate-limits/cursor-desktop-profile-worker*.ts). Orca already runs OpenCode's
database reads on a worker, and more foreign-app SQLite reads are coming, so
keeping one worker per app means one entry, build input, asarUnpack line, knip
entry and guard line each. This keeps one pattern instead: Cursor's
state.vscdb read runs on the shared foreign SQLite reader entry, and the
dedicated worker, its entry and its config lines are deleted.

What moves:
- The read itself is a pure cursorProfile reader in
  foreign-sqlite-readers/readers/ (was rate-limits/cursor-desktop-state-db.ts),
  run only on the worker. A separate dispatch owns the new kinds and refuses
  an unknown kind. The entry routes OpenCode kinds to the untouched OpenCode
  dispatch, so the relay's OpenCode reader stays byte-identical.
- ForeignSqliteReaderClient gives each reader its own WorkerThreadRequestQueue
  lane (own lazily started, idle-torn-down thread; one shared factory) with
  in-flight dedupe per database path. Any failure resolves to the reader's
  existing failure value and never falls back to the main thread.

Kept from #24572, so every reader gets them:
- Await worker retirement before respawning. Worker.terminate() cannot
  interrupt a native SQLite call (e.g. a WAL-index rebuild), so the old
  thread lives on until that call returns; respawning at once stacked a new
  thread on the same work for every timed-out read (#24572 measured three
  live workers). This belongs in the shared host, which fire-and-forgot
  terminate(): LazyWorkerThreadHost now takes awaitRetirement and refuses to
  spawn until the terminated worker settles, and the queue fails calls closed
  meanwhile. Opt-in, because pure-JS clients (session scanner abort, port
  scan) respawn right after an abort. A rejected terminate() also ends
  retirement, so it cannot latch the reader off (raised in #24572's review).
- 10 s Cursor timeout, 2 consecutive deaths, a queue cap of 8.
- #24572's worker tests, rewritten against the shared client: responsive
  caller plus coalesced probes, unavailable worker without path leaks,
  stalled-worker recovery, no respawn before retirement, dispose settles.

Tests: reader, dispatch, client (timeout, 10 s default, crash, malformed,
unavailable without a main-thread read, dedupe, queue cap, own thread per
reader), queue retirement (stalled and rejected terminate), import boundary,
and an event-loop test reading a ~50 MB WAL with no -shm on a real worker.

* test(sqlite): walk the reader import boundary with the shared source-tree scan (STA-9122)

* fix(sqlite): key reader dedupe on a caller-supplied key, not the path alone (STA-9122)

* Skip slower root package-store restores in Linux PR jobs (#24896)

* test: advance mocked Claude child exit deadlines (#24897)

* perf(tab-bar): a change to one tab no longer re-renders every tab (#24261)

With many tabs open, a change to any one tab (a retitle, an agent finishing, a tab switch, a git status write, or a browser tab update on SSH and web clients) re-rendered every tab in the strip, so the strip stuttered. Each tab is now a memoized row that re-renders only when its own values change, with stable handlers, a stable drag id list and stable drag sensor options. Editor tabs get their own git status, and mirrored browser tabs keep their page-id list while the ids don't change.

Part of #24241: opening, closing or reordering a tab still re-renders every tab once.

* fix(opencode): read the binder's session store off the main thread; ship the reader worker in orcad (#24638)

* fix(opencode): read the binder's session store on the foreign SQLite reader worker (STA-9122)

Before: the OpenCode session binder listed new sessions from opencode.db with
node:sqlite on the main thread every 60 s (and on SessionStart kicks), so a
large or contended store could stall the app the same way Cursor's did.

After: the read is a pure openCodeBinderSessions reader in
foreign-sqlite-readers/readers/, run only on the worker. The binder's
correlation, pane snapshot and process sweep stay where they were.

- The binder round awaits listSessions and re-checks its generation right
  after, so a stop() during the read discards the round before it touches the
  unbound map or the watermark.
- The client's in-flight dedupe key now includes the cursor, so a stale round
  from before a restart cannot hand its rows to the restarted round.
- Idle teardown is per reader. The binder lane keeps its thread for 120 s,
  longer than its 60 s poll, so the thread is not respawned every round.
- A timeout, crash, malformed reply or unstartable worker resolves to [] (no
  sessions), the value the old read already returned on failure.
- An absent store still reads as [] without a log line, and a permission or
  corrupt-file failure still logs (kept from #24577, now in the reader: it
  stats the path and throws anything but ENOENT/ENOTDIR to the client's log).
- The binder lane inherits #24572's limits from the shared lane: no respawn
  until a timed-out worker has exited, 2 consecutive deaths, a queue cap of
  8. Its timeout stays 60 s, matching its poll.
- dispatch switches on the destructured kind, so a new kind without a case
  still fails to compile.

orcad: the hook server runs there too, so orcad now ships
foreign-sqlite-reader-entry.js beside orcad.js (ORCAD_ARTIFACTS, built as an
orcad child). build-orcad runs a smoke check that starts the built worker
under the build's Node and under the pinned runtime, and does a real binder
read on a fixture DB, a Cursor read of a missing file and an OpenCode history
list. The OpenCode history scanner uses the same entry and was bundled into
orcad without it, so on orcad it always failed closed; it can now run.

Tests: reader (cursor, same-ms ids, OpenCode 2 rows, missing then created,
corrupt, inaccessible directory), retirement gate for the binder lane, dispatch
routing, client lane (rows, failure -> [], dedupe per cursor, own thread, idle
teardown default and override), binder loop with an async listSessions
(failure -> [], stop during the read), orcad path resolution through orcad's
host adapters, artifact list, and the smoke check against good, missing and
non-reading entries.

* test(opencode): cover the binder read deadline with fake timers and name the failure test accurately (STA-9122)

* refactor(ai-vault): delete the unused session-scanner worker thread (#24607)

* refactor(ai-vault): delete the unused session-scanner worker thread

Production always scans through the forked session-scanner service process;
the worker thread was reachable only under NODE_ENV=test or the
undocumented ORCA_AI_VAULT_SERVICE_PROCESS=0 switch, and nothing fell back
to it on service failure. Remove the thread (spawn, client, protocol, entry,
tests), its build entry, knip and plain-node-guard listings, and the
backend switch, so session-scanner-background always routes to the service.

- Move the scan options type to the service protocol as
  AiVaultServiceScanOptions.
- Tests now mock session-scanner-service-spawn, the seam production calls.
- Repoint the hot-path listing reliability gate from the worker-client test
  to the service-client test, which covers the same bounded-queue,
  cancellation, and fault-restart properties for the real executor.

* fix(native-chat): one ordered journal writer (#24127)

* fix(claude): settle a queued send the CLI withdrew from its own cancelled frame

Claude reports each uuid-stamped command's lifecycle (queued, started,
completed, cancelled). A send it withdraws from its queue gets `cancelled`
before the interrupt or cancel_async_message answer, so a lost or failed
answer no longer leaves that send pending: it settles as withdrawn, with the
same reason and words as the receipt path.

A command the CLI already started also ends `cancelled` when its turn is
interrupted or fails, so `cancelled` after `started` is not a withdrawal;
an echoed send has left the waiter lists and is never reached.

Tests replay real 2.1.280 captures, scrubbed.

* fix(claude): release a doubted send when the CLI reports its session idle

A Claude send whose write ended in doubt is recorded `unknown`, and a live
`unknown` reads as work still owed, so the chat showed Working until the
child exited. Claude sends `session_state_changed idle` only once its whole
queue has drained, so it can no longer be holding that send. The runtime now
routes that report to the host's existing release, the same one Codex's
thread-stopped report uses; it retires `unknown` only, never `pending`.

* fix(claude): settle every terminal lifecycle state of a send the CLI never echoed

A send the CLI started, then cancelled before any echo, stayed pending: it may
already be in the conversation, so it is released as doubt (unknown, recovered),
never withdrawn and never re-sent. A late echo still accepts it.

The 2.1.280 schema has two more terminal states. `discarded` (the CLI ended its
session with the send still queued) settles as not delivered; `refused`
(declined before it queued) settles as not accepted by the provider. After
`started`, either one is doubt, as `cancelled` is.

The late-settlement path gains an `unknown` outcome, which the host records as
released doubt.

* fix(claude): release a send the CLI took but left unanswered when it goes idle

`session_state_changed idle` comes only once the CLI's queue has drained, so a
send it took that is still unanswered there got no echo and never will: a turn
that throws can leave `started` with no terminal state. Idle releases it as
doubt.

What proves the CLI took a send is its lifecycle frame. On a CLI that reports no
lifecycle, it is the send's place on stdin: one whose write finished before an
interrupt went out was read before the interrupt was, so the first idle after
that interrupt releases it too. A send armed ahead of the interrupt but written
after it is left alone, since the CLI may still run it.

* fix(native-chat): keep the idle sweep off a Claude child that holds a send

A Claude retrying a rate-limited request has taken the send but echoes nothing,
so no turn row exists yet and the sweep rested the child after the idle window,
turning the send into doubt. The adapter now reports whether the CLI holds a
send (lifecycle `queued` or `started`, not yet echoed or ended), derived from
the live waiters, and owed work counts it.

Nothing is stored: every held send leaves the live set on its echo, its
terminal lifecycle state, the CLI's idle, or the child's exit, so the hold ends
with the send.

* fix(claude): count only a started send at idle and as a held send

2.1.280's end-of-turn cleanup can report idle before it re-reads its queue, so
a send read in that window goes queued, idle, started. Releasing every taken
send at idle doubted that live send and dropped Working. Only a `started` send
is released at idle or keeps the child from the idle sweep; a `queued` one ends
by starting and echoing, by a terminal lifecycle frame, or with the child.

The stdin-order path for CLIs without lifecycle frames is removed: a doubted
send retired there disables content matching on CLIs that mint their own echo
ids, and no Orca failure called for it. Those CLIs keep the earlier behaviour.

Comments that said only a failed write or child exit ends a waiter, or that
idle comes only once the queue has drained, now say what ends one.

* docs(claude): say only what the CLI's lifecycle frames and idle actually prove

* fix(claude): hold the idle sweep while Claude has a send queued, not only started

The sweep rested a child whose CLI had queued a follow-up behind a turn, dropping
the send it had already taken. The hold now spans the CLI reporting it took the
send until its echo, a terminal lifecycle state, or the child's exit. The idle
release still covers only started sends: 2.1.280 can report idle before it
re-reads its queue.

* refactor(native-chat): give provider-proven late dispatch settlement its own module

* test(claude): pin a steer a Stop interrupts after it started as doubt, not withdrawn

* fix(native-chat): one ordered journal writer

Every journal write, streamed or direct, lands in the chat's one write queue
in the order it is issued, and has landed in the fold when its call returns
(except while an owed import is paid, when it lands in queue order). The event
sink stops being a queue ahead of it; journal-write coalescing, which moved a
replaced write to the tail, is removed; closing a sink no longer loses writes
already handed over. The ten flushStreamedEvents patches go. A streamed text
item takes its place at its first delta, so a direct write inside the
coalescing window never lands above text already streamed. A Stop interrupts
whatever its bookkeeping writes do.

* fix(native-chat): a failed Stop holds the lane until its queue pause lands

A Stop whose note write or stop call failed skipped the wait for its
withdrawal and pause, so the lane freed first; with writes queued behind
owed work, the drain could hand the waiting card to the agent after Stop.

* fix(native-chat): a journal write body is typed synchronous

The queue's ordering rule needs every write body to finish before it returns;
serialize still took a promise-returning body, so an await inside one would
let a later write land first. The body type now refuses a promise.

* fix(native-chat): a stream's first window snapshot always lands

The first-delta write counted as the growth checkpoint, so the window's
snapshot was skipped until 32 more characters arrived: a stream showed only
its first token, and a Codex reasoning row could sit as an empty aside. The
coalescer now marks the row-creating emit and the first snapshot after it,
and both providers' growth throttles write those.

* test(native-chat): streamed text rewritten in place above a Stop note

Covers a stream whose later deltas wait in the window across a Stop, for
Codex and Claude, and a Codex item completed inside the window.

* chore(native-chat): drop comments that still describe coalesced journal writes

* fix(native-chat): type the draft-table write body synchronous too

* fix(native-chat): an empty delta owes no streamed-text emit

The opening snapshot is forced past the growth rule, so an empty second
Codex delta rewrote the row with identical text. The coalescer now marks a
stream dirty only when a delta adds text.

* fix(native-chat): a mutation's open pays an owed import first

With the flushes gone, a Stop naming no turn, a goal set or a /clear could
read the fold while provider rows still waited behind a restore's owed
import: the Stop answered cancelled:false and interrupted nothing. The open
every mutation shares now waits for the import, as a reader's does; a failed
import is reported and never refuses the mutation.

* chore(native-chat): whenImported says mutations await it too

* test(native-chat): a Stop interrupts before its withdrawal or pause settles

Pins the order for a write that is held and then fails, for a Stop naming
its turn and one naming none.

* test(native-chat): a Stop ends a starting child before its withdrawal or pause settles

* test(native-chat): Stop order tests wait for the interrupt, not a 50 ms timer

* test(native-chat): settlement-order test reads rows through the journal row parser

Replaces a Reflect.get field walk, which the low-evidence audit rejects, with
parseJournalRow and the named row types.

* fix(native-chat): an empty delta still owes its emit, just not a forced one

The previous fix stopped an empty delta from marking the stream dirty, which
broke the pinned contract that an empty stream is snapshotted and flushed.
The coalescer now marks a stream dirty on every delta and tracks separately
whether its text changed since the last emit; only a changed snapshot is
the opening one that skips the growth throttle.

* revert(native-chat): drop the first-text row write from the delta coalescer

The immediate first-delta emit (and the opening flag and counters it needed)
had no Orca-observed failure behind it and added a journal commit per
streamed item. The coalescer, the Claude checkpoints and the tests that
pinned the first-text row go back to main's behaviour; the one ordered
writer, the sink hand-off and the Stop rules stay.

* fix(worktrees): list a folder once when git reports it twice (#24357)

When git lists the same folder twice (a leftover worktree registration that points at the main checkout), Orca's runtime listing turned each line into its own worktree with the same id, so `orca worktree current`, `active` and `branch:` failed with selector_ambiguous, and paired clients saw a duplicate row. The runtime scan now keeps git's first row per folder, the rule the desktop sidebar already uses. Separately, for a bare or separate-git-dir repo added through a linked worktree, the scan no longer relabels the main row with that worktree's folder (it relabels only when the folder's git dir is the common git dir), so the worktree keeps its own row and branch in the CLI and the sidebar. No extra git command runs.

Part of #23631: the "Profile state writer command timed out" toast in that issue has a separate cause.

* fix(worktrees): a worktree delete git fails partway stays listed and can be retried (#23952)

* fix(worktrees): delete removed checkouts in git, not in Orca's file pool

Local worktree removal renamed the checkout into a sibling trash root and
deleted it in the background with a recursive fs.rm in the main process.
That queued one request per entry on libuv's shared 4-thread file pool, so
for minutes every other async fs call in the main process (the agent-session
store behind chat sends, file explorer reads) waited behind the delete.

`git worktree remove` now deletes the checkout inline in git's own process
again, so the card stays in its Deleting state for the length of the delete
while Orca's file pool stays free. No timeout applies to the call, so a
large delete is never killed halfway.

If git reports success but the path still exists (Git for Windows leaves
junctions and their parent directories in place), the leftover is deleted
with the existing removeHostTree; WSL checkouts stay with the distro.

Nothing creates trash any more: the scheduling queue, rename/restore
helpers and the trash_rename span are gone. The startup sweep stays to
drain entries older releases left behind, and now removes each emptied
trash root so the obligation ends.

* fix(worktrees): let Git delete Windows checkouts with long paths enabled

Removal now always runs Git's own recursive delete, and worktree creation
checks out with core.longpaths on Windows, so a deep checkout Orca created
could fail to delete with "Filename too long" (#6433). The Windows recovery
then finishes the delete but keeps the branch. Pass the same command-scoped
core.longpaths option to `git worktree remove` so Git can delete what it
created.

Also point the CI shard timing entry at the renamed real-git removal suite.

* fix(worktrees): keep an inherited GIT_ASK_YESNO out of the worktree delete

Git for Windows asks $GIT_ASK_YESNO whether to retry when a file stays
locked during a recursive delete. Orca's git env inherits the user's
environment, so an inherited value would run an arbitrary prompt program
in the middle of a removal. Drop it for the removal call only.

* perf(worktrees): run worktree deletes under their own limit, outside git admission

`git worktree remove` now deletes the whole checkout in Git's own process,
which takes 20-35 s on a large tree. It took a general git admission slot at
status tier for that whole time, and that cap is as small as two slots on a
machine with six or fewer cores, so two deletes blocked every status read.

Deletes now skip general admission and queue under their own limit of two
per host instead: two concurrent deletes already saturate one disk, and more
only slow each other down. Leftover cleanup runs inside the same slot.

* fix(worktrees): delete removed checkouts in the background and mark them removing

Since the checkout is deleted by `git worktree remove` in Git's own process,
a large delete takes 20-35 s. Answering the request only after that made web
and mobile (30 s), paired desktop (60/180 s) and the CLI (60 s) report a
failure for a delete that was still going, and mobile silently re-showed the
row.

The request now does everything that can refuse (lock, cleanliness, archive
hook, watcher/terminal gate, terminal stop, shared-link unlink), records the
removal in an in-memory table on the host and answers `removing: true`. The
delete, branch cleanup and metadata purge run after it in the same order as
before, and the watcher/terminal gate stays held until they finish.

- Listings mark rows in the table `removing` for clients that advertise
  `worktree.background-removal.v1` (the desktop renderer, paired desktop and
  web), and leave them out for everyone else (older clients, mobile, the
  CLI), which already dropped the row when the request answered.
- The outcome (removed, with any preserved branch, or the error) rides the
  existing worktrees-changed event as an optional field, sent after the row
  has left the table.
- A repeat delete while Git runs joins it. A create at the same path or with
  the same branch is refused with "Cleanup is pending; try again shortly";
  create's name search skips the path, so generated names move on.
- Nothing is persisted: after a quit or crash Git still lists the checkout
  and it can be deleted again. WSL checkouts still delete inline.
- `orca worktree rm` says the checkout is still being deleted.

* fix(worktrees): keep the existing Deleting card until the host's Git finishes

The host now answers a local worktree delete on acceptance and deletes in the
background. The renderer keeps the existing delete state set until the host
publishes how it ended:

- The delete that asked waits for the outcome on the worktrees-changed event
  (local IPC or the paired runtime's client event), then runs the same
  teardown, preserved-branch toast and card error an inline delete did. If
  that event is lost to a dropped connection, a listing that shows the row
  gone after it was marked removing finishes the wait, and one that shows it
  back without the marker fails it.
- Any other renderer (a reload, a paired desktop, web) sets the same delete
  state from the host's `removing` marker and clears it when the marker goes.
  A failure the host publishes lands on that card's existing error.
- Web advertises `worktree.background-removal.v1` so the host sends it the
  marker; paired desktop does through the Electron capability list.

No new component, style or state: the card reads the delete state it always
did. A host that predates this answers when done without `removing`, and the
renderer takes that as finished, as before.

* test(worktrees): type the removal harness and projection for the node typecheck

* fix(worktrees): don't fail a delete retry with an earlier attempt's buffered failure

A background removal's outcome that reached this renderer with no waiter (another client's
delete, a host-marked card, or one already settled from listings) was buffered for 60 s and
consumed by the next delete of the same workspace, so retrying a failed delete failed at once
with the old error while the host was deleting. Drop the buffered outcome before sending the
request; only an outcome that arrives after it can belong to it.

* fix(worktrees): let only a gap in host events settle a background delete from listings

Git unlists the checkout before the host deletes the branch, cleans the push target and purges
metadata, and the worktree-directory watcher refetches within 250 ms. The renderer read the
missing row as a finished delete, so the waiter resolved without the preserved branch (no
toast) and a failure in those last steps showed as success; the real outcome was then dropped.
The listing fallback exists only for a lost outcome event, so it now applies only after this
host's event stream had a gap: a new subscription or a replay after reconnect.

* perf(worktrees): let a bulk delete start each same-repo checkout delete once the host accepts the last

A bulk delete ran one worktree at a time per repo (#2259, for packed-refs and ref-lock races in
branch cleanup). With Git now deleting each checkout for 20-35 s before the request settles, N
worktrees in one repo took N times that. The renderer now queues same-repo deletes only until
the host accepts each one; a parent still waits for its nested children to finish. The host
serializes the branch cleanup step per repo itself, which also covers removals started by
different clients.

* test(worktrees): pin the host platform in the mocked removal suites so they pass on Windows

Removal now passes -c core.longpaths=true on Windows, so the exact-argv
assertions and command-keyed mocks never matched there (17 failures on a
Windows host). Pin darwin as the add-worktree suites already do, and drive
the one Windows-specific case through the same spy.

* test(worktrees): type the blocked git remove result instead of a broad object

The anti-slop static-analysis gate rejects `object` parameters.

* test(worktrees): clear the changed-code quality gate in the removal suites

Merge the duplicate node:fs import, build the mock child without a cast, read
worktrees:list rows through one typed helper, and give the remaining casts a SAFETY line.

* fix(worktrees): record each background delete durably and finish it after a quit or crash

A quit mid-delete left git to finish the checkout on its own while the branch
delete and metadata purge never ran; a crash left a normal-looking row. Each
accepted local removal now writes a record beside the profile state before git
starts, clears it on success or failure, and the host runs the same delete
again for any record left at startup, re-deriving what remains from git and
disk. An orderly quit stops the checkout delete without waiting for it.

* test(worktrees): type the interrupted-removal assertions for the node typecheck

* fix(worktrees): finish an interrupted delete that already removed the checkout's .git file

Quit stops git worktree remove mid-delete, and Git deletes the checkout's .git
file wherever it falls in directory order. Git then refuses the checkout
("validation failed ... .git does not exist") on every retry, so the startup
finish failed and the row could never be deleted from Orca. A registered
checkout this record owns that has lost its .git file now finishes like an
unregistered one: leftover files, prune, then the branch.

* fix(worktrees): let Git finish an interrupted delete, and never take a different checkout

A quit or crash that stops `git worktree remove` after it deleted the checkout's
.git file left a registered checkout Git refuses to remove. The previous fix
deleted that leftover inside Orca's process, which is the bulk delete this
change exists to avoid (and on Windows the leftover can be most of the
checkout). The startup finish now rewrites the missing .git file from Git's
own admin entry for that path and lets `git worktree remove --force` delete
it. `git worktree repair` is not used: it also re-points every other
registered path, including a checkout another repository now owns there.
Orca deletes the leftover itself only when no admin entry claims the path.

The startup finish forces, so it now leaves the path alone when the checkout
there is not the one recorded: a registered worktree on a different branch or
head, or a `.git` at a path Git already unregistered. The record is dropped and
the card shows why.

The record write before Git starts is now bounded (2 s, logged when exceeded)
so a stalled disk cannot hold the delete, and the outcome is published before
the record's clear reaches disk.

* test(worktrees): compare worktree paths by value and tear down with Windows lock retries

Git prints forward slashes in `git worktree list` on Windows, so the real-Git
removal suites never found a joined path there: positive checks failed and
negative ones passed without proving anything. They now compare Git's parsed
rows by value. Teardown uses the shared retrying removeTree, since Windows can
hold the deleted checkout busy for a moment after Git exits. Adds a
relative-path worktree case for the .git restore (skipped before Git 2.48).

* fix(worktrees): reply to a worktree delete when it has finished, not on a broadcast event

A current client's delete request now waits for the host's background delete and gets its real
result (removed, a preserved branch, or the error) as the reply, the way it did before the delete
moved off the request. A request that arrives while the delete runs joins it and gets the same
result. Every other view keeps reading the host's `removing` marker: the row leaving means the
delete finished, and the row listed again without the marker shows "The delete did not finish.
Try again." on a card that view had marked Deleting. A request whose reply is lost (a timeout or a
dropped connection) settles the same way from a fresh listing instead of reporting a failure.

Clients without the background-removal capability (mobile, the CLI, older desktops) are still
answered on acceptance and have rows under removal left out of their listings.

This removes the outcome on worktreesChanged and everything it needed: the renderer's outcome
waiters, early-outcome buffer and TTL, per-host event-gap generations, the request pre-registration,
and the accept callback bulk delete used. Bulk delete runs same-repo deletes in parallel only on
this machine, whose host serializes branch cleanup per repo; SSH and paired hosts stay serialized.

* test(worktrees): type the pending-removal host id in the background-removal suite

* fix(worktrees): answer a delete request even when a concurrent removal of the same worktree replaced its record

The desktop app's removal and the runtime removal (CLI, paired clients) coalesce separately, so
both can be accepted for one worktree. The second replaced the first's record, and the first
delete then finished without resolving the request waiting on it, leaving the desktop card on
Deleting indefinitely. Each delete now settles the request it was started for.

* fix(worktrees): run same-repo removal archive hooks and teardown one at a time on the host

Local bulk delete now sends same-repo removals in parallel, so their archive hooks, terminal
teardown and preflight ran at once; a hook that writes refs can race the repo's ref locks
(#2259). The host now serializes each local removal up to acceptance per repo, for every
client; Git's checkout delete still runs in parallel under the delete limit.

* fix(runtime): keep waiting worktree deletes out of a host's foreground call slots

worktree.rm now replies only after Git deletes the checkout (up to minutes), so on paired
desktop and web each waiting delete held one of the host's 8 foreground call slots, and a
bulk delete queued listing refreshes and every other foreground call behind it. Deletes now
run in their own lane with the same bound; the 2-slot background lane stays for status polls.

* fix(worktrees): join a same-worktree delete accepted while a removal waited its repo turn

The desktop app and the runtime (CLI, paired clients, web) check for a running delete before
they queue for the repo's acceptance turn. A delete of the same worktree from the other path,
accepted while this one queued, was missed: this request re-ran the archive hook, stopped the
terminals again and started a second `git worktree remove` on the directory Git was deleting.
The queued acceptance now re-checks and joins the running delete.

* fix(worktrees): fence a resumed delete's checkout from startup, and drop rows a listing read before the delete finished

A delete a quit or crash interrupted took its terminal and file-watcher gate only when the resume
job ran, after the first window was shown; session restore could open a shell or watcher inside the
half-deleted checkout first, and on Windows that handle can fail the resumed git delete. Loading the
records now fences each recorded path, and the resumed job takes the fence over in the same tick it
takes its own gate.

A listing that read git's registration before a delete finished, and replied after the removal
record cleared, returned the row unmarked, so other views briefly showed "The delete did not
finish". Listings now capture the pending removals before reading git and leave out a row whose
delete finished successfully since; a row whose delete failed stays listed as before.

* test(worktrees): keep git's auto-maintenance out of the real-git removal suite

CI's Git 2.55 failed the file-pool test in teardown with ENOTEMPTY on the scratch repo's
objects/pack after the test body passed: the 3,000-file commit's detached auto-maintenance was
still writing a pack. The scratch repo now disables auto-maintenance and auto-gc.

* fix(worktrees): one archive-hook approval covers a same-repo bulk delete again

Local same-repo deletes now start together, so each queued its trust prompt with a state snapshot
taken before the first prompt was answered; approving the first still showed the same prompt once
per remaining worktree. The queued check now reads the store when its turn comes.

* fix(worktrees): a delete Git fails partway stays listed with its error; Delete retries it

`git worktree remove --force` drops the checkout's registration even when it
cannot delete a file (root-owned files, `chflags uchg`, a read-only Windows
directory). Orca lists workspaces from Git, so the row vanished after the error,
leaving the checkout, the branch and Orca's metadata with no way to retry.

- A background delete that fails with the checkout still on disk, unregistered,
  and still the removed checkout's own leftover keeps its durable removal record
  with the error (`failure`) instead of clearing it. Every other failure clears
  it as before.
- Local listings (desktop list/list-all/detected, runtime list/ps/detected)
  add a row for each such record, carrying `removalError`, and for a pending
  removal whose checkout Git no longer lists (shown as removing).
- Delete on that row (desktop IPC and runtime worktree.rm) runs the recorded
  removal again: terminal teardown, then the leftover, prune, branch and
  metadata, under the per-host delete limit.
- The record ends on a successful retry, when the checkout is gone (listing or
  startup)…

* fix(source-control): generate PR details before Create PR on a ready branch (#24215)

* fix(source-control): generate PR details before Create PR on a ready branch

A pushed branch sent the placeholder title and empty body, skipping the
configured agent. A run Create PR submits unreviewed keeps the user's base
and never unchecks Draft; the Generate button is unchanged.

Fixes #22824

* docs(source-control): correct the auto-submitted Draft rule comment

* fix(source-control): never let generated details uncheck the user's Draft box

A Draft choice made before generation started was unprotected: the form only
keeps fields whose revision changed *while* a run was in flight, so a user who
checked Draft and then pressed Generate had the box silently unchecked by an
agent answering draft:false, and the next Create PR opened a real review ready
for review. Scope the rule to provenance rather than the in-flight window, and
apply it to reviewed runs and the prepare-branch route too, so the agent can
still flag unfinished work but never reverts a choice the user made.

* test(source-control): cover the Checks panel create-after-run and superseded-run guards

Two guards had no failing test. The Checks panel's Create PR must still send
the finished run's details while its last render shows the run as generating,
or the click silently creates nothing. Each panel's generation must return no
result when a later run replaced its record (Stop, then Generate finishing
first), or the stopped Create PR click would open a PR with the later run's
details.

* fix(source-control): don't reveal a background-created PR over another worktree

Create PR on a ready branch now waits for the agent, and the create still
runs if the sidebar panel closes meanwhile. When it finished, it always
opened the sidebar on Checks (and, with "open after create", the review),
even if the user had switched to another worktree, so Checks showed the
wrong worktree and the in-app link route switched the user back.

Reveal only when the created review's worktree is still selected, or the
panel that made it is still mounted, like the prepare-branch route.

* fix(source-control): keep Create PR in flight while the agent writes the details

Create PR on a ready branch generated the details and then created nothing,
with no message. When generation ended, Source Control's eligibility check
restarted and cleared the eligibility, and the create, which reads the panel's
latest state, returned early on the missing eligibility.

The click now stays in flight from the start of generation until the create
settles, as the prepare-branch route does, so the eligibility check stays
paused and the create sees the eligibility it started with. Repeated clicks
are counted so one returning early can't release another's hold.

* refactor(source-control): move Checks created-review linking into its own hook

No behavior change. The Checks panel's create hook was at its 400-line limit;
linking and refreshing a created review now lives in
use-checks-panel-created-review.tsx, the way Source Control keeps it in
use-hosted-review-created.ts.

* fix(source-control): finish a started Create PR run for the branch that was clicked

After the agent wrote the details, Create PR read the panel's latest render
instead of the state at the click. That render could have lost its
eligibility (no PR, no message), still show the run as generating, or show
another branch. Navigating away also gave opposite results: with the sidebar
open on another worktree no PR was made; after closing the sidebar first, it
was.

The create now always runs through the click's own closure, so a started run
creates the PR for the branch that was clicked wherever the user went, like
the prepare-branch route. The reveal still follows the selected worktree, so
nothing opens over another one. The "still shows generating" bypass in both
panels is gone: the click's render never shows the run as generating.

In the Checks panel, a create that returns after the panel moved to another
worktree still links the review to the clicked worktree and clears its
push-first flag; only the in-flight state, errors, opening the review and
the GitLab checks refresh are skipped, since they belong to whatever the
panel now shows. The same holds for a push-first create whose push finishes
after the panel moved.

* refactor(source-control): let the Create PR click own the in-flight flag

The click already kept Source Control's create in flight through generation,
so the composer stays up instead of closing while eligibility refreshes. It
did that with a per-worktree click counter next to the create's own in-flight
flag, so a repeated click that returned early couldn't end the first click's
hold.

Now the click owns the existing in-flight flag from the click until the
create settles, and a click while it is set is refused before it touches
anything, so the counter is gone. This matches what the UI already did:
Create PR is disabled while the flag is set, including after Stop until the
stopped request returns. Since the create now runs through the click's own
state, the hold only keeps the UI steady; it no longer decides whether a PR
is created.

* docs(source-control): describe the created-review foreground check by what callers pass

The Checks panel now passes whether it still shows the created review, not
just whether it is mounted, since a mounted panel can have moved to another
worktree while the create ran.

* fix(source-control): release Create PR as soon as Stop lands

After Stop, Source Control's Create PR stayed disabled ("Creating...") until
the stopped generation request came back. Locally that is under a second, but
when the cancel can't reach a slow or disconnected remote host the button
stayed disabled for up to the 75 s generation timeout.

A generation run's outcome now settles as soon as its record stops running,
not when the request returns. Stop marks the record canceled at once, so the
click that started the run ends, its hold is released, and the next click
submits the form as shown. The stopped request still finishes in the
background; its late result is dropped because the record is no longer
running for that request. Both panels' generation handlers use the same
helper.

## ELI5

When a Windows terminal stress test stalls, its old log cannot show where progress stopped. The test now records bounded, sanitized lifecycle observations while keeping its existing assertions and timing.

## What Changed

Record output-pipe, worker, native exit and final callback milestones, pending state at existing deadlines, and hashes of the native addon and supporting files. Redact addresses and credentials even when terminal controls split them, preserving the controls’ positions. Keep the warmup survivor and newest 31 terminals; later terminals still receive observers, with omissions counted explicitly.

## Why

[The failing Windows job](https://github.com/stablyai/orca/actions/runs/37132029374/job/111229398978) had one silent terminal and at least one undrained callback. [An earlier passing job](https://github.com/stablyai/orca/actions/runs/37123932023/job/111205697896) used the same source and cache inputs, without a loaded-addon hash. Observing the existing objects supplies missing evidence while preserving the gate. Bounded recent records retain the terminals most likely involved in a late failure.

## Linked Issue

Diagnosis of PR #25031’s Windows package failure. This does not claim that the original native cause is fixed or close a product issue.

## Visual Proof

N/A — test diagnostics add no UI or interaction change.

## Testing

- [ ] I manually tested these changes locally
- [x] Automated tests added and updated for reproduced failures.

On the exact previous public helper, eight strengthened controls failed and six passed. They reproduce control-interrupted credential/address leaks, omitted late terminals after eleven rounds, and late state after the 256-milestone cap. Independent review then reproduced six more leaks on the intermediate helper: usernames and hostnames masked only part of an email. The final helper runs the existing same-length redactor a second time, removing the remaining private domain while preserving controls and OSC framing. Those six before failures and two credential-overlap controls are retained. Corrected source `5037c18a898571539ade5336ad3519cd49dfb20f` passes 171 controls in four files, including all 22 observer controls, the full anti-slop audit, syntax/AST checks, focused format/lint and six quality gates.

The previous public source `f1ed3e97` passed [actual Windows CI](https://github.com/stablyai/orca/actions/runs/37136703455/job/111243011997): 25 PTYs, eight rounds, 526 passing tests and 26 skips, plus build, package and smoke checks. Its native stress/driver files remain exact here; the observer has changed, so fresh normal CI must qualify this complete correction. The passing run’s native-addon hash differs from the historical failure; it does not explain that failure.

## Review

All four original diagnostic files and public ancestry are retained; all 32,245 paths outside that scope match main `786a040b`. The existing redactor runs twice on a view with presentation controls removed, then controls are restored at their original positions; OSC framing separates title payloads from adjacent text. Logs retain 32 terminal records and 256 milestones with explicit omissions, plus bounded final snapshots. The native callback preserves its receiver, arguments, result and thrown errors; error observers preserve unhandled-error behavior.

Native assertions, deadlines, input, concurrency and cleanup remain exact. Companion hashes identify file bytes rather than in-memory DLL equivalence. The original native cause remains unverifiable.

## Agent skill upstream boundary

- [x] Not applicable; no upstream skill source is copied.

## Notes

No production API, RPC, native patch, dependency or workflow change. Blank output or a missing callback is not evidence of process death. Local helper controls run on macOS; the existing real ConPTY gate exercises Windows.

## Checklist

- [x] Small, focused diagnostic scope.
- [x] Explained the before/after, mechanism and choice.
- [x] Visual proof N/A with reason.
- [x] Self-reviewed privacy, bounded logging and callback behavior.
- [x] Cross-platform and remote impact considered.
- [ ] Fresh normal Windows CI must qualify the complete corrected source.

* fix(cli): orca file open opens PDFs and other binaries like the File Explorer (#24445)

files.open gated the desktop open on the mobile preview list, so PDFs returned opened:false with ok:true. The host now opens every file after an existence/directory check; the CLI fails loudly if an older host still declines.

Fixes #24328. Builds on #24331.

* Update README downloads badge

* refactor(orchestration): one function for six agent-to-agent sends (#24901)

* refactor(orchestration): send every agent-to-agent message through one sendAgentTurn

The structured mail-pointer lane and the structured worker preamble each carried a copy of
"send, wait out a pending start, read the verdict", and four dispatch-preamble sites typed into
a terminal directly. They now share sendAgentTurn, built from host.send, the host's settlement
waiter and sendTerminalAgentPrompt. Every caller passes delivery 'now', so nothing sends
differently; a source-scan ratchet keeps new direct sends out.

* test(orchestration): the refusal fixture uses a real wire refusal code

* fix(orchestration): derive the send fingerprint inside sendAgentTurn and pair target with turn

A `queue` send was refused by a real host: callers supplied a fingerprint over the body alone
while the host digests body and delivery. sendAgentTurn now builds the envelope with the
composer's own builder (extracted to structured-agent-session-send-mutation), so the fingerprint
is always over exactly the fields sent; `now` sends keep the identical digest. The pointer lane
no longer carries a fingerprint it cannot get right.

sendAgentTurn takes one argument, a union on kind that carries its own target and turn, resolved
by an exhaustive switch; the terminal turn names its purpose (only the dispatch preamble today)
instead of every terminal send inheriting the task lead line. A queued outcome keeps the host's
draft receipt, and both structured callers read outcomes exhaustively with unchanged behaviour.

The boundary test now also fences direct structured host sends, catches optional, bracket and
bound member uses, has a planted-offender self-test, and pins the unmoved terminal mail pointer
and agent-teams tmux senders.

* feat(native-chat): a Claude subagent waiting on a permission prompt reads as waiting (#22634)

* feat(native-chat): a Claude subagent waiting on a permission prompt reads as waiting

A subagent's permission request reaches the parent session's callback naming the
subagent that asked (agent_id) and the tool call it gates (tool_use_id). The
pending request is recorded with the asking agent. On every drain the child-work
producer re-derives which children a pending request blocks and hands that set
to the Claude child decoder, the one owner of each child's live edges: a blocked
child reads waiting on every live edge it reports, and a child that starts or
stops waiting is a live edge of its own. Answering, denying or cancelling the
request returns the child to its prior live state; nothing is stored beyond the
pending requests.

A live task_updated carrying an error now reaches the record as the child's last
message, without an ending or a new state.

The replay test drives a scrubbed capture of the real CLI (foreground allow,
deny, interrupt, background allow, and the main agent's own request) through the
real adapter into the host's child records.

* test(native-chat): a subagent's request names it before its tool call is read

* docs(agent-status): a subagent asking for approval waits in every lane; the parent row keeps the session's own attention

* test(native-chat): hand canUseTool the asking agent without widening the helper's cast

* test(native-chat): an interrupted Claude subagent settles cancelled, not failed

A captured interrupt shows the spawn call's error result ("The user doesn't want
to proceed…") arriving before the subagent's own `task_updated {status: killed}`.
The spawn result ends nothing (the child ends only on its own terminal frame), so
the child stays live until its `killed` status settles it cancelled. A genuine
failure, captured with the subagent on a model that does not exist, sends its
`failed` status before the error result and still ends failed. Both captures now
replay through the real adapter into the host's records.

* fix(native-chat): a Claude subagent's prompt makes the parent row wait, not block

A subagent's pending prompt made the whole session `attention`, which reads as
the main agent's own `blocked` and outranks the fold's waiting arm, so the
parent row read blocked where a CLI Claude parent reads waiting. The main
agent's state now reads only its own pending prompts.

- A Claude prompt row carries the linkage of the agent that raised it: the one
  the permission request names, or the owner of the tool call it gates. The
  same join decides which child reads waiting, so the two cannot disagree.
- The status summary projects the session's own status from root prompts only;
  every other reader (delivery gates, teardown, restart) still asks whether
  anyone is waiting on a human.
- An answer keeps the prompt row's linkage by the journal's own rule: a
  revision that names no producer keeps the row's existing one.
- The child-tool queries gain the prompt's producer, so a prompt row and a
  child record answer "which agent" from the same join.

* test(native-chat): say which ids the permission capture scrubs and which are its own

* fix(native-chat): the status clock dates attention by the session's own asks only

The session's status is now `attention` only for its own pending prompt, so the
clock's fallback to a subagent's ask could no longer be reached, and it read the
journal by a different rule than the status it dates. Both now read root prompts.

The journal also stamps a Codex subagent's prompt with its thread (#22532), so a
Codex child's approval is that child's wait in the Codex lane too. Two tests
written for the earlier rule are updated: a subagent's ask leaves a running
session `working` on its turn's clock, and a Codex child's answered approval
leaves the settled parent's Activity row done with nothing unread.

* fix(native-chat): a completion still says the user is asked when a subagent asks

The turn-completion feed marked a completion `awaitingUser` from the status
summary's `attention`. The status now means the session's own agent is waiting,
so a subagent's pending approval stopped reaching the completion. The projection
now also says whether anyone is waiting on the user, as the delivery gates,
teardown and restart ask it, and the completion reads that.

The waiting-subagent replay answers its prompt with the adapter's current
response shape.

* revert(native-chat): a live Claude task's error stays out of the child's last message

No capture shows a live task_updated carrying an error, and it is unrelated to
a subagent waiting on a permission request; it leaves this PR.

* test(native-chat): settle the Claude session's startup before replaying a subagent's request

A startup frame drained child work during the first await, so answering a
request freed the child even with the answer's own republish removed.

* fix(native-chat): a Claude subagent's prompt row names it as its other rows do

The prompt row stamped only the asking agent's id, so a nested subagent's
request lost the agent that spawned it, its spawn call and its run. It now takes
the linkage the asker's own rows take: the gated tool call's, when that names the
same agent, else the one resolved through the agent's spawn call. The provider's
agent id stays the asker's id.

* fix(native-chat): a subagent's request makes the parent row wait without a child record

The parent row learned that a subagent needed the user only from that
subagent's child record, so a request no record carried (a Codex child the host
never registered, a Claude task past the live cap) left the row working or done
while the approval card sat in the chat.

"Someone in this session must answer" is now one derived session fact. The
projection names two facts instead of a mode flag: the main agent's own status
(attention only for its own request) and structuredAgentSessionAwaitsUser (any
pending prompt). The status summary publishes the second as an optional
awaitsUser, and the shared fold reads it: the main agent's own ask is blocked,
otherwise awaitsUser or a waiting child record makes the row wait. Every caller
picks the fact it means: the completion edge's awaitingUser and the delivery
gate read awaitsUser; the quit snapshot folds the same two inputs the sidebar
does.

* fix(native-chat): a client that predates awaitsUser still reads a subagent's request as attention

A status summary's status is now the main agent's own, so a client built before
the split would read a subagent's request as working (or idle) and fold it with
code that has no awaitsUser input. Clients advertise
agent-session.status-awaits-user.v1; at agentSession.subscribeStatus the host
sends any client that does not the pre-split summary: attention whenever
awaitsUser is set, without the main agent's own tool line, verdict and clock.
The feed and every in-process reader keep the canonical summary. Transitional,
like the turn-item downgrade.

* test(native-chat): a Codex subagent's approval makes its settled parent's Activity row wait

The test pinned the parent row done while a Codex child asked, through a harness
that fed no child records, so it proved nothing about the ask. It now drives the
ask twice through the real host status store: with no child record (the
session's awaitsUser alone) and with the child's own record waiting from
thread/status/changed. Both read waiting with needsAttention while the ask is
open, then done with nothing unread.

* docs(agent-status): a subagent's request reaches the parent row through awaitsUser in every structured lane

The store reference said a Codex child's request still read as the main agent's
blocked and that only the Codex hook lane fed a waiting child. Both structured
lanes stamp the asking child and feed child records, and awaitsUser carries the
request when no record does. The liveness comment goes back to main's: a child's
blocked is a failed task on an older host's legacy rows.

* fix(native-chat): the restart dialog still headlines a subagent's pending approval

The quit snapshot now records the main agent's own state, so a subagent asking
while the main agent worked recorded `working` and the dialog said "Was
mid-reply" where it used to say "Waiting for your approval". The headline now
comes from the snapshot's pending prompt, whoever raised it, with the existing
copy; `state` stays the main agent's own.

* test(orchestration): a subagent's pending approval holds structured mail delivery

Scoping the delivery gate to the main agent's own request left every gate test
green; a subagent's request now has its own case.

* fix(native-chat): a subagent's request is dated by when it was raised, on every client

Since the summary's clock became the main agent's own, nothing dated a wait
that only a subagent's request held: a pre-split client was sent attention with
no clock, where the old host dated it by the subagent's prompt, and a new
client's waiting row fell back to the time it first saw it, so after a reload a
request the user had already read could read unread again.

The session fact is now when someone started being asked: awaitsUserSince, the
oldest pending prompt whoever raised it, and its presence is what awaitsUser
meant. A row waiting on someone else's request takes that as its clock; the
downgrade for a client without the capability dates its attention by it, which
is what the old host published. A cross-version test pinned to the last
pre-split release runs the same journals through that release's projection and
through this one plus the downgrade, and compares the whole summary. The Codex
end-to-end test also reads the host's own status row, and keeps a read ask read
through a later row and a reload.

* test(native-chat): the pre-split parity check compares only the fields the split owns

An additive summary field is safe for old clients, so comparing whole summaries
against the pinned release would redden on one. The wire comment now says how
the downgrade dates attention: the main agent's own oldest ask, else
awaitsUserSince.

* test(runtime): an aged host-held working summary states that nobody is asked

The test built its working summary by overriding the status of a published
approval summary, which still carried awaitsUserSince, so the row correctly
read waiting. It now drops the request as its scenario says.

* fix(native-chat): the chat's subagent block says waiting when the strip does

While a Claude subagent's request was open, the sidebar and the composer strip
read waiting but the subagent block in the chat history a few pixels above
still read "Kicked off 1 subagent working": it shows the journal's roster
state, and the journal records no wait.

The structured chat now hands its transcript the subagents the strip shows
waiting, read from the host's child records through the strip's own row model
and matched by the provider id the roster names each one by. A running entry
the host says is waiting reads waiting in the group row, its entry and its
section head, with the strip's word and the question colour; it reads the
journal's state again as soon as the host stops reporting the wait.

* fix(native-chat): a collapsed subagent group shows a wait beside a failed sibling

A failed sibling took the group row's one alert slot, so a group with a waiting,
a working and a failed child read "1 working +1 failed" and hid the wait; it
now reads "1 working +1 waiting +1 failed". The waiting set keeps its identity
while a child frame changes no wait, so the transcript's subagent rows do not
re-render on every frame, and the test of a wait ending now updates one mounted
row instead of remounting it.

* refactor(claude): one needs-input state on the parent; the asking subagent alone reads waiting

Drop the split of the main agent's own status from a session-wide "someone must
answer" fact: awaitsUserSince, the agent-session.status-awaits-user.v1
capability and its old-client downgrade, and every reader change that only
consumed them (fold, equality, ingest, delivery gate, turn-completion feed,
quit snapshot, resume headline, status clock, status bridge, attention
dispatch) go back to main. The parent row again reads one needs-input state
for a pending request whoever asked, dated as before.

Kept: a request's owner recorded once on its prompt row with full producer
linkage; the asking subagent's own record reads waiting, re-derived on every
update; the chat history's subagent block reads that same state; an answered
subagent request stays in its subagent's group.

A subagent now waits only on a request the user can still answer (its card
open, no answer underway), and the adapter frees it before the host records an
answer or dismissal. So a waiting child record always sits beside the pending
card, and main's fold never reads the parent as waiting on it: no window after
an answer, and no ~3 s wait after a card dismissed by Stop.

* fix(claude): a subagent waits only beside its committed card

A subagent's wait was pushed to the host as soon as its request arrived,
while the request's card row reached the journal at least a microtask later.
So every subagent request published the parent row as waiting before
blocked (the main agent's own fold reads a waiting child that way), and
Activity got an extra unread "waiting" event that main never shows.

The card is now the one record of an open request. The translator records
the asker on the card once (its row's linkage) and counts the card open only
after the sink confirms its rows landed, then publishes the wait; anything
that closes the card (an answer underway, a dismissal handed to the host,
Claude's own withdrawal, the session's end) frees the subagent first. So
every publish that shows a subagent waiting also shows its pending card, and
the parent reads one needs-input state, exactly as on main.

This retires the registry's view of pending requests (unclaimed(), the
asking-child join) and the translator's holdsOpen. The prompt row's linkage
takes one rule: the agent the provider names, else the gated call's owner.

The parent-row proof now runs through the real deferred sink, durable
journal and status feed, publishing as production does, and checks at every
publish that waiting subagents have pending cards and that the parent row
matches a host fed no waits.

* fix(native-chat): a closed sink's dropped writes never read as landed

The sink's written() resolved ok when the sink was closed with writes still
queued, so a subagent's prompt card could count as open with no row in the
journal. written() now reports a close that dropped writes admitted so far
as not landed; drained() and lifecycleBarrier() keep reading a closed sink as
settled.

Tests: a card never opens when its sink closes first; a card Claude withdraws
while the sink holds the cancelled row back closes at once; two subagents
asking at once, and the main agent asking beside a subagent, keep the parent
row as before with each waiting subagent beside its own card; a process that
dies mid-request leaves no subagent waiting.

* fix(claude): a withdrawn subagent request frees its child before its card closes

Main's sink now hands each write to the journal as it is submitted, and an idle journal commits it
and runs the publication at once. Claude's own withdrawal of a subagent's request therefore closed
the card and published the parent row before the child's wait was freed, so one publish showed the
subagent waiting beside no pending card (fg-interrupt replay). The child's wait now also requires the
request to still be open in the registry, and a withdrawal republishes child work before the
journal takes the close.

* refactor(claude): trim subagent request waiting to the common pattern and its essential tests

The chat history no longer marks a subagent block as waiting: the approval card itself carries the
request, and the asking subagent's row in the sidebar and composer strip reads waiting, as before.
NativeChatWaitingSubagentsProvider, native-chat-waiting-subagents.ts and their renderer changes go.

A subagent waits while its request is still open and unanswered in the prompt registry and its card
has landed in the journal. The registry check also covers a withdrawal under backpressure, so the
card list no longer filters pending cancellations itself.

Tests: one integration file replays the captured CLI frames through the real adapter, sink, journal
and status feed (renamed claude-subagent-permission-request.test.ts), with the asking subagent's
state timeline, attribution, nested linkage and a card write that waits for the journal. The
producer-harness waiting test, the redundant prompt-card cases, the harness reducer swap and three
unused captures (deny, interrupt, main agent, failed subagent) are removed.

* fix(orchestration): derive the send fingerprint inside sendAgentTurn and pair target with turn

A `queue` send was refused by a real host: callers supplied a fingerprint over the body alone
while the host digests body and delivery. sendAgentTurn now builds the envelope with the
composer's own builder (extracted to structured-agent-session-send-mutation), so the fingerprint
is always over exactly the fields sent; `now` sends keep the identical digest. The pointer lane
no longer carries a fingerprint it cannot get right.

sendAgentTurn takes one argument, a union on kind that carries its own target and turn, resolved
by an exhaustive switch; the terminal turn names its purpose (only the dispatch preamble today)
instead of every terminal send inheriting the task lead line. A queued outcome keeps the host's
draft receipt, and both structured callers read outcomes exhaustively with unchanged behaviour.

The boundary test now also fences direct structured host sends, catches optional, bracket and
bound member uses, has a planted-offender self-test, and pins the unmoved terminal mail pointer
and agent-teams tmux senders.

* feat(native-chat): a Claude subagent waiting on a permission prompt reads as waiting (#22634)

* feat(native-chat): a Claude subagent waiting on a permission prompt reads as waiting

A subagent's permission request reaches the parent session's callback naming the
subagent that asked (agent_id) and the tool call it gates (tool_use_id). The
pending request is recorded with the asking agent. On every drain the child-work
producer re-derives which children a pending request blocks and hands that set
to the Claude child decoder, the one owner of each child's live edges: a blocked
child reads waiting on every live edge it reports, and a child that starts or
stops waiting is a live edge of its own. Answering, denying or cancelling the
request returns the child to its prior live state; nothing is stored beyond the
pending requests.

A live task_updated carrying an error now reaches the record as the child's last
message, without an ending or a new state.

The replay test drives a scrubbed capture of the real CLI (foreground allow,
deny, interrupt, background allow, and the main agent's own request) through the
real adapter into the host's child records.

* test(native-chat): a subagent's request names it before its tool call is read

* docs(agent-status): a subagent asking for approval waits in every lane; the parent row keeps the session's own attention

* test(native-chat): hand canUseTool the asking agent without widening the helper's cast

* test(native-chat): an interrupted Claude subagent settles cancelled, not failed

A captured interrupt shows the spawn call's error result ("The user doesn't want
to proceed…") arriving before the subagent's own `task_updated {status: killed}`.
The spawn result ends nothing (the child ends only on its own terminal frame), so
the child stays live until its `killed` status settles it cancelled. A genuine
failure, captured with the subagent on a model that does not exist, sends its
`failed` status before the error result and still ends failed. Both captures now
replay through the real adapter into the host's records.

* fix(native-chat): a Claude subagent's prompt makes the parent row wait, not block

A subagent's pending prompt made the whole session `attention`, which reads as
the main agent's own `blocked` and outranks the fold's waiting arm, so the
parent row read blocked where a CLI Claude parent reads waiting. The main
agent's state now reads only its own pending prompts.

- A Claude prompt row carries the linkage of the agent that raised it: the one
  the permission request names, or the owner of the tool call it gates. The
  same join decides which child reads waiting, so the two cannot disagree.
- The status summary projects the session's own status from root prompts only;
  every other reader (delivery gates, teardown, restart) still asks whether
  anyone is waiting on a human.
- An answer keeps the prompt row's linkage by the journal's own rule: a
  revision that names no producer keeps the row's existing one.
- The child-tool queries gain the prompt's producer, so a prompt row and a
  child record answer "which agent" from the same join.

* test(native-chat): say which ids the permission capture scrubs and which are its own

* fix(native-chat): the status clock dates attention by the session's own asks only

The session's status is now `attention` only for its own pending prompt, so the
clock's fallback to a subagent's ask could no longer be reached, and it read the
journal by a different rule than the status it dates. Both now read root prompts.

The journal also stamps a Codex subagent's prompt with its thread (#22532), so a
Codex child's approval is that child's wait in the Codex lane too. Two tests
written for the earlier rule are updated: a subagent's ask leaves a running
session `working` on its turn's clock, and a Codex child's answered approval
leaves the settled parent's Activity row done with nothing unread.

* fix(native-chat): a completion still says the user is asked when a subagent asks

The turn-completion feed marked a completion `awaitingUser` from the status
summary's `attention`. The status now means the session's own agent is waiting,
so a subagent's pending approval stopped reaching the completion. The projection
now also says whether anyone is waiting on the user, as the delivery gates,
teardown and restart ask it, and the completion reads that.

The waiting-subagent replay answers its prompt with the adapter's current
response shape.

* revert(native-chat): a live Claude task's error stays out of the child's last message

No capture shows a live task_updated carrying an error, and it is unrelated to
a subagent waiting on a permission request; it leaves this PR.

* test(native-chat): settle the Claude session's startup before replaying a subagent's request

A startup frame drained child work during the first await, so answering a
request freed the child even with the answer's own republish removed.

* fix(native-chat): a Claude subagent's prompt row names it as its other rows do

The prompt row stamped only the asking agent's id, so a nested subagent's
request lost the agent that spawned it, its spawn call and its run. It now takes
the linkage the asker's own rows take: the gated tool call's, when that names the
same agent, else the one resolved through the agent's spawn call. The provider's
agent id stays the asker's id.

* fix(native-chat): a subagent's request makes the parent row wait without a child record

The parent row learned that a subagent needed the user only from that
subagent's child record, so a request no record carried (a Codex child the host
never registered, a Claude task past the live cap) left the row working or done
while the approval card sat in the chat.

"Someone in this session must answer" is now one derived session fact. The
projection names two facts instead of a mode flag: the main agent's own status
(attention only for its own request) and structuredAgentSessionAwaitsUser (any
pending prompt). The status summary publishes the second as an optional
awaitsUser, and the shared fold reads it: the main agent's own ask is blocked,
otherwise awaitsUser or a waiting child record makes the row wait. Every caller
picks the fact it means: the completion edge's awaitingUser and the delivery
gate read awaitsUser; the quit snapshot folds the same two inputs the sidebar
does.

* fix(native-chat): a client that predates awaitsUser still reads a subagent's request as attention

A status summary's status is now the main agent's own, so a client built before
the split would read a subagent's request as working (or idle) and fold it with
code that has no awaitsUser input. Clients advertise
agent-session.status-awaits-user.v1; at agentSession.subscribeStatus the host
sends any client that does not the pre-split summary: attention whenever
awaitsUser is set, without the main agent's own tool line, verdict and clock.
The feed and every in-process reader keep the canonical summary. Transitional,
like the turn-item downgrade.

* test(native-chat): a Codex subagent's approval makes its settled parent's Activity row wait

The test pinned the parent row done while a Codex child asked, through a harness
that fed no child records, so it proved nothing about the ask. It now drives the
ask twice through the real host status store: with no child record (the
session's awaitsUser alone) and with the child's own record waiting from
thread/status/changed. Both read waiting with needsAttention while the ask is
open, then done with nothing unread.

* docs(agent-status): a subagent's request reaches the parent row through awaitsUser in every structured lane

The store reference said a Codex child's request still read as the main agent's
blocked and that only the Codex hook lane fed a waiting child. Both structured
lanes stamp the asking child and feed child records, and awaitsUser carries the
request when no record does. The liveness comment goes back to main's: a child's
blocked is a failed task on an older host's legacy rows.

* fix(native-chat): the restart dialog still headlines a subagent's pending approval

The quit snapshot now records the main agent's own state, so a subagent asking
while the main agent worked recorded `working` and the dialog said "Was
mid-reply" where it used to say "Waiting for your approval". The headline now
comes from the snapshot's pending prompt, whoever raised it, with the existing
copy; `state` stays the main agent's own.

* test(orchestration): a subagent's pending approval holds structured mail delivery

Scoping the delivery gate to the main agent's own request left every gate test
green; a subagent's request now has its own case.

* fix(native-chat): a subagent's request is dated by when it was raised, on every client

Since the summary's clock became the main agent's own, nothing dated a wait
that only a subagent's request held: a pre-split client was sent attention with
no clock, where the old host dated it by the subagent's prompt, and a new
client's waiting row fell back to the time it first saw it, so after a reload a
request the user had already read could read unread again.

The session fact is now when someone started being asked: awaitsUserSince, the
oldest pending prompt whoever raised it, and its presence is what awaitsUser
meant. A row waiting on someone else's request takes that as its clock; the
downgrade for a client without the capability dates its attention by it, which
is what the old host published. A cross-version test pinned to the last
pre-split release runs the same journals through that release's projection and
through this one plus the downgrade, and compares the whole summary. The Codex
end-to-end test also reads the host's own status row, and keeps a read ask read
through a later row and a reload.

* test(native-chat): the pre-split parity check compares only the fields the split owns

An additive summary field is safe for old clients, so comparing whole summaries
against the pinned release would redden on one. The wire comment now says how
the downgrade dates attention: the main agent's own oldest ask, else
awaitsUserSince.

* test(runtime): an aged host-held working summary states that nobody is asked

The test built its working summary by overriding the status of a published
approval summary, which still carried awaitsUserSince, so the row correctly
read waiting. It now drops the request as its scenario says.

* fix(native-chat): the chat's subagent block says waiting when the strip does

While a Claude subagent's request was open, the sidebar and the composer strip
read waiting but the subagent block in the chat history a few pixels above
still read "Kicked off 1 subagent working": it shows the journal's roster
state, and the journal records no wait.

The structured chat now hands its transcript the subagents the strip shows
waiting, read from the host's child records through the strip's own row model
and matched by the provider id the roster names each one by. A running entry
the host says is waiting reads waiting in the group row, its entry and its
section head, with the strip's word and the question colour; it reads the
journal's state again as soon as the host stops reporting the wait.

* fix(native-chat): a collapsed subagent group shows a wait beside a failed sibling

A failed sibling took the group row's one alert slot, so a group with a waiting,
a working and a failed child read "1 working +1 failed" and hid the wait; it
now reads "1 working +1 waiting +1 failed". The waiting set keeps its identity
while a child frame changes no wait, so the transcript's subagent rows do not
re-render on every frame, and the test of a wait ending now updates one mounted
row instead of remounting it.

* refactor(claude): one needs-input state on the parent; the asking subagent alone reads waiting

Drop the split of the main agent's own status from a session-wide "someone must
answer" fact: awaitsUserSince, the agent-session.status-awaits-user.v1
capability and its old-client downgrade, and every reader change that only
consumed them (fold, equality, ingest, delivery gate, turn-completion feed,
quit snapshot, resume headline, status clock, status bridge, attention
dispatch) go back to main. The parent row again reads one needs-input state
for a pending request whoever asked, dated as before.

Kept: a request's owner recorded once on its prompt row with full producer
linkage; the asking subagent's own record reads waiting, re-derived on every
update; the chat history's subagent block reads that same state; an answered
subagent request stays in its subagent's group.

A subagent now waits only on a request the user can still answer (its card
open, no answer underway), and the adapter frees it before the host records an
answer or dismissal. So a waiting child record always sits beside the pending
card, and main's fold never reads the parent as waiting on it: no window after
an answer, and no ~3 s wait after a card dismissed by Stop.

* fix(claude): a subagent waits only beside its committed card

A subagent's wait was pushed to the host as soon as its request arrived,
while the request's card row reached the journal at least a microtask later.
So every subagent request published the parent row as waiting before
blocked (the main agent's own fold reads a waiting child that way), and
Activity got an extra unread "waiting" event that main never shows.

The card is now the one record of an open request. The translator records
the asker on the card once (its row's linkage) and counts the card open only
after the sink confirms its rows landed, then publishes the wait; anything
that closes the card (an answer underway, a dismissal handed to the host,
Claude's own withdrawal, the session's end) frees the subagent first. So
every publish that shows a subagent waiting also shows its pending card, and
the parent reads one needs-input state, exactly as on main.

This retires the registry's view of pending requests (unclaimed(), the
asking-child join) and the translator's holdsOpen. The prompt row's linkage
takes one rule: the agent the provider names, else the gated call's owner.

The parent-row proof now runs through the real deferred sink, durable
journal and status feed, publishing as production does, and checks at every
publish that waiting subagents have pending cards and that the parent row
matches a host fed no waits.

* fix(native-chat): a closed sink's dropped writes never read as landed

The sink's written() resolved ok when the sink was closed with writes still
queued, so a subagent's prompt card could count as open with no row in the
journal. written() now reports a close that dropped writes admitted so far
as not landed; drained() and lifecycleBarrier() keep reading a closed sink as
settled.

Tests: a card never opens when its sink closes first; a card Claude withdraws
while the sink holds the cancelled row back closes at once; two subagents
asking at once, and the main agent asking beside a subagent, keep the parent
row as before with each waiting subagent beside its own card; a process that
dies mid-request leaves no subagent waiting.

* fix(claude): a withdrawn subagent request frees its child before its card closes

Main's sink now hands each write to the journal as it is submitted, and an idle journal commits it
and runs the publication at once. Claude's own withdrawal of a subagent's request therefore closed
the card and published the parent row before the child's wait was freed, so one publish showed the
subagent waiting beside no pending card (fg-interrupt replay). The child's wait now also requires the
request to still be open in the registry, and a withdrawal republishes child work before the
journal takes the close.

* refactor(claude): trim subagent request waiting to the common pattern and its essential tests

The chat history no longer marks a subagent block as waiting: the approval card itself carries the
request, and the asking subagent's row in the sidebar and composer strip reads waiting, as before.
NativeChatWaitingSubagentsProvider, native-chat-waiting-subagents.ts and their renderer changes go.

A subagent waits while its request is still open and unanswered in the prompt registry and its card
has landed in the journal. The registry check also covers a withdrawal under backpressure, so the
card list no longer filters pending cancellations itself.

Tests: one integration file replays the captured CLI frames through the real adapter, sink, journal
and status feed (renamed claude-subagent-permission-request.test.ts), with the asking subagent's
state timeline, attribution, nested linkage and a card write that waits for the journal. The
producer-harness waiting test, the redundant prompt-card cases, the harness reducer swap and three
unused captures (deny, interrupt, main agent, failed subagent) are removed.

* Reuse prepared reads while searching saved agent conversations (#24535)

Use schema-complete session columns to enable the existing bounded statement cache without caching result rows.

* test(terminal): restore the live fish fixture prerequisites (#24947)

A restored pane waits for the initial status replay before subscribing to
PTY output. This fixture never settled that replay, so fish printed its
mode-2031 arm before the renderer connected. Its PTY API also omitted the
reset-input listener required by the serializer, aborting attachment.

Settle and dispose the existing startup-snapshot registration and provide
the same reset-listener mock used by the other PTY tests. The real fish
child-stdin assertions and timeouts remain unchanged. No production change.

* Record hosted automatic-mode cold cache publication proof

* fix: bound remote generation setup and honor OpenCode option terminators

Count execution-host profile resolution inside the existing request deadline, cancel its waiter promptly, and pass only the remaining time to the child. Shared bounded profile probes keep their existing cache lifetime; the SSH transport margin is unchanged.

Read OpenCode output format from active final-argv options before -- so literal prompt arguments cannot select the JSON finalizer.

Fresh exact-source controls reproduce nine failures before; 139 related checks pass after, including primary/fallback delays, deadline boundaries, cancellation, parser metadata, and SSH lanes. Node typecheck and strict changed-file lint pass.

* test(jcode): measure the gate against the synchronous path, not the clock

The absolute 1s bound was the flake CI shard 3/8 hit: it is tight enough to catch
a synchronous gate on an idle laptop and too tight on a loaded runner. Measuring
the same POST both ways on the same machine makes the claim a ratio, which is what
the test is actually about. Mutation-checked: a synchronous gate reads 6120ms
against a 1517ms observer.

* test(jcode): drop the wall-clock gate assertion

The bound was machine-speed sensitive and flaked on CI shard 3/8 at 1525ms. The
structural assertions (detached gate branch, foreground observer branch) and the
no-hang stdin drain cover the same contract without a timer.

* fix(jcode): address CodeRabbit review on #22539

- Windows posted no payload at all: the shared builder reads `payload@-` from
  stdin, which the gate has already drained and observer hooks never receive, so
  every Windows event was dropped. Write the env var to a temp file and pipe it.
- The daemon pre-warm never fired for daemon-host spawns, which is the default
  local path; it now runs there too, and from the final env so the daemon gets the
  hook port and token.
- A failed runtime-dir mkdir took down every local terminal, jcode or not.
- removeJcodeManagedHooks matched the raw line, so a user hook whose comment
  mentioned the managed script was deleted; matching on Windows never worked.
- A managed entry left by a copied home or a platform switch is now repointed
  instead of being reported as user-owned forever.
- The OSC colour skip only checked launchAgent, so a command- or telemetry-named
  jcode pane still leaked the reply into its composer.
- `['hooks']` and a commented scalar are recognised, instead of appending a
  second [hooks] table that makes jcode reject the whole config.
- A failed tool's error is marked as tool output rather than agent prose.
- The vault keeps a session's stored name, counts its tokens, and skips
  background_task and [Scheduled task] turns.

* fix(jcode): read the journal once per turn, key prompts by byte offset

The jcode prompt reader ran a synchronous bounded file scan plus a JSON
parse on every hook event. jcode blocks on pre_tool, so a turn that ran
four tools charged the user eight scans of latency it did not need — the
prompt cannot change inside a turn.

- Cache the journal read per pane, refreshed on the turn boundary that
  can change it. The cache holds the whole evidence record, since
  hasExplicitUserPrompt needs the transcript-evidence flag and not just
  the text, and it joins the existing pane-scoped lifecycle (close,
  rename, reset) rather than living in a module singleton.
- Key a journal prompt by its absolute byte offset instead of its
  region-local line index. The backward scan windows the file from EOF,
  so appending shifted every boundary and reminted the key for a prompt
  that never moved; a repeated turn_end then slipped past the same-hash
  dedupe as a second done event with duplicate telemetry.
- Pin the platform in the daemon pre-warm tests. The pre-warm is a no-op
  off POSIX, so the dedupe and retry cases would have passed vacuously
  on a Windows runner.

* fix(jcode): quote the managed hook path, drop tools from patch prompts

Three fixes, all on paths this PR could not exercise locally.

The managed hook command was stored as a bare path. jcode tokenizes that
string shell-style before exec'ing it directly (parse_hook_command,
crates/jcode-terminal-launch/src/lib.rs): unquoted whitespace splits, and
every unquoted backslash is consumed as an escape. So on Windows
`C:\Users\me\.orca\agent-hooks\jcode-hook.cmd` reached exec as
`C:Usersme.orcaagent-hooksjcode-hook.cmd` and no hook fired at all, and a
POSIX home with a space split into two arguments. Store the path
single-quoted (verbatim, backslashes included), falling back to double
quotes for a path containing a single quote. Existing bare entries are
already repointed by the stale-key path, and getStatus accepts both forms
so the repair is not reported as a user-owned hook. The quoting helper was
previously dead code that only tests called; the three production sites
now use it. isJcodeManagedCommand also normalizes separators, since a
`/`-only needle never matched a Windows entry.

Commit-message generation feeds a staged patch to `jcode run` as the
prompt — attacker-influenced text — while jcode's default profile exposes
shell, read, write, and MCP. Pass `--tool-profile none`, which resolves to
an empty allowed-tool set in jcode's config (base_allowed_tools), matching
the read-only posture claude (plan) and codex (read-only) already take.

docs/reference/jcode-hook-events.md was never actually in this PR: the
repo ignores docs/** and tracks reference docs by allow-list only, so the
captured-payload evidence four source comments point at was silently
dropped. Allow-list it.

* test(jcode): pin the tool-profile flag in the generation plan too

The argv assertion lives in two places; --tool-profile none only landed in
one, so the plan test still expected the unrestricted argv.

Co-authored-by: czzczz <chanzrz_zbf@foxmail.com>

* fix(text-generation): refuse an oversized argv prompt on Linux too

The pre-spawn size guard only ran on Windows. Linux caps a single argv
entry at MAX_ARG_STRLEN (32 pages, 128 KiB on a 4-KiB-page host) and
execve fails with E2BIG past it, so an agent that delivers the whole
prompt as one argument — jcode, and the other argv-delivery agents —
failed on a large staged diff with an error the user could not act on.

The cap is per-argument and in bytes, which is why it is not the Windows
line budget: 40k chars trips Windows and is nowhere near the Linux limit,
so folding them together would have refused prompts Linux runs fine.

* fix(jcode): register in main's remote-installer guard, drop our duplicate

Rebasing onto 853 commits of main surfaced two things the earlier branch
had hidden.

main already owns a guard for the issue-#7253 bug class
(`remote-hook-service-registry-coverage.test.ts`). This branch had added a
second, near-identical one — a parallel implementation of a test that
already existed, which is what AGENTS.md's reuse rule is about. Deleted
ours and registered jcode in main's, which is the one that has kept pace
with every agent added since.

Also fixes a missing separator in the mobile icon map. `pnpm tc` does not
cover `mobile/`, so only the session-route closure suite caught it.

* fix(jcode): decompose the four files jcode pushed over max-lines

Adding an agent tipped four modules past their line budget. AGENTS.md
forbids a `max-lines` disable or a per-file bump, so each is split on a
real seam rather than silenced:

- agent-catalog.tsx keeps `AgentIcon`, which 70+ files import, and the
  rows move out. The rows alone exceed the 300-line budget a `.ts` file
  gets, so they follow the primary/secondary split this repo already uses
  for commit-message agent specs.
- getAgentResumeArgv -> agent-resume-argv.ts, re-exported so the 18 call
  sites keep one import path.
- isDiscoverableSessionFile/pathSegments -> session-file-discovery.ts.
- remoteCodexSources -> remote-session-scanner-codex-sources.ts; Codex is
  the one remote agent with two CODEX_HOME roots.

Also:
- Records the readiness-census baseline jcode now needs. main added that
  gate while this branch was out; the fixture is the recorded 74-case
  matrix, not a hand-written one.
- Restores two entries a rebase resolution silently dropped from
  config/tsconfig.cli.json (gitlab/project-ref-parser,
  startup/shell-path-probe). Nothing to do with jcode; losing them was a
  conflict-resolution mistake on this branch.

* feat(native-chat): open structured chats on the paired Orca server that owns the workspace (#24205)

* fix(native-chat): a host admits structured sessions by client capability, not its own chat setting

A host's experimentalStructuredNativeChat decided whether any paired client could reach
agentSession.* at all, and whether session.tabs.* showed it structured tabs. That setting is the
host user's own launch preference: whether a new agent opens as a chat or a terminal is decided by
whoever launches it. Using it as admission control meant a client whose own preference was
"structured chat" was refused on a host whose preference was "terminal", and chats opened while
the setting was on were withheld from mobile once it was turned off.

The gate now asks one thing: did the client advertise agent-session.structured.v1 (in-process
callers negotiate nothing and are always admitted). Tab projection and restore follow the same
rule. With the setting no longer gating anything, the separate cleanup gate (close, cancel,
unsubscribe, release), which existed only so those kept working after the setting was switched
off, is identical to the main gate and is folded into it. The settings listener that republished
tabs when the setting changed is removed, since projection no longer depends on it.

The host setting still picks the default for launches that start on the host itself
(agent.launch from mobile, orchestration worker-start).

* fix(native-chat): the desktop declares structured chat support to paired hosts

The desktop renderer advertised agent-session.structured.v1 (and the Claude, turn-item and
background-task capabilities that go with it) to its own main process but not to a paired Orca
server. The server therefore refused every agentSession.* call from the desktop and stripped
structured chat tabs out of the tab list it published to it, so a structured chat running on a
paired server never appeared on the desktop, even though the renderer already mirrors a host's
agent-session tabs and drives each one against the server that owns its workspace.

The same renderer reads structured chats on either host, so the remote Electron list now carries
the same structured-session capabilities as the local one, and the capability test pins that
nothing is advertised only locally.

* feat(native-chat): open structured chats on the paired server that owns the workspace

With the structured-chat default on, an agent launched in a workspace that lives on a paired Orca
server always opened as a terminal (or the terminal-backed chat view). Three things kept it off
the structured path: the launch check refused every host but this machine, a remote workspace was
handed to the host-published terminal path before the structured route was even considered, and
the structured launch pipeline sent create and every follow-up call to this machine's runtime.

A workspace's owning runtime is fixed, so the pipeline now derives it from the workspace instead
of assuming this machine (structured-agent-session-owner.ts, the same derivation the chat pane
already uses to read a session). The launch intent carries that target; the pre-create support
check, create, the publication check and fence read, the launch prompt send, held option picks,
the "focus this chat" marker, the placeholder tab's host, and tab close/purge all use it.

The launch check now accepts a paired server and asks that server's own capabilities (read from
the status the client already cached for it) rather than this machine's. An SSH workspace stays
terminal-backed: no Orca runtime runs there. The host still answers createSupport before
anything is created, so an older server that refuses shows the failure in the chat tab.

A chat the user closed before its create landed is now also retired on the paired server when it
publishes, as the local sync already does. Orchestration workers placed on another runtime are
unchanged: federation creates terminal agents only.

* fix(native-chat): negotiate client-chosen launch mode so released phones and old servers keep terminals

Hosts advertise agent-session.structured.client-launch-mode.v1: they admit
structured sessions by client capability alone. A remote client that does
not advertise it (phones released before agent.launch) asks createSupport
to pick the launch mode, so the host keeps answering that with its own
setting, exactly as before. Cleanup methods keep their own named gate so a
future admission condition cannot make close or cancel refusable.

* refactor(runtime): keep the Electron client capability list in its own module

protocol-version.ts is at its line budget; the list is what the desktop
advertises to paired hosts, not the host's own contract.

* fix(native-chat): the desktop declares it picks each launch mode itself

Paired hosts and the desktop's own main process then answer createSupport
by the workspace rather than by their own chat setting.

* fix(native-chat): pin each structured chat to the host it was launched on

- Route: a paired server opens a chat only when it advertises the
  client-chosen launch mode; an older server keeps its terminal. Its
  capabilities come from the store's host status, not the compatibility
  cache that is empty after boot or reconnect.
- A launch command override is this machine's: the route applies it only
  locally, and a host's createSupport refuses on its own override.
- The owning host is resolved once, from the same value the route used,
  and carried on the launch intent, its persisted record (legacy records
  load as local), the provisional tab and every mirrored chat tab. Close,
  purge, retry and reload read it instead of re-deriving it from a
  worktree id two hosts can share; an owner that cannot be named refuses.
- Cancellation tombstones record their host: only that host's
  authoritative inventory retires one, restored cleanup closes it there,
  and a paired host's tombstone expires after 30 days if it never answers.
- A paired server's frame settles launches it published, as the local
  inventory already does for this machine.

* fix(native-chat): a paired server that declines a chat opens its terminal instead

createSupport only reads, so both of its non-answers are settled before
anything is created:
- A paired server that answers it cannot run the chat (a WSL repo, a
  Claude account mismatch, its own launch command override) closes the
  chat tab and opens the terminal the route would have chosen, with a
  notice saying why. This machine's own decline stays a failed chat.
- A host that could not be asked closes the chat tab and leaves one
  failure toast, instead of a lingering "could not confirm" chat.

* test(native-chat): a provisional chat carries its launch's host and hands pre-create failures on

* chore(native-chat): justify the two type assertions this change's lines touch

* test(native-chat): state why each staged test fixture is cast

* fix(native-chat): chats that already exist keep showing whatever the chat setting says

The structured chat setting decides only what new agents open as. With it
off, this machine's structured chats used to be hidden while the host,
which no longer reads the setting, still reported them to the workspace
activation gate, so a workspace holding only a chat opened empty. The
local chat mirror and its startup restore now run whatever the setting
says, the continue-after-restart offer follows the chats that exist, and
the setting's copy says it applies to new agents.

* fix(native-chat): the browser client keeps its host terminal on paired servers

A browser client whose own preferences turn structured chat on took the
structured route for every paired-server workspace, but its handshake
never says it reads structured sessions, so the server refused the chat
and the user got a failed chat tab where a host terminal used to open.
The route for a paired host now also asks what this client advertises to
it: the desktop's list does, the browser client's does not. Its handshake
list is now a named constant the route reads, so the two cannot drift.

The chat setting's copy now says it runs on paired Orca servers too;
WSL and SSH hosts still use terminal chat.

* fix(native-chat): a retried launch a paired server declines opens its terminal too

A launch restored after a reload settles only through its Retry, so a
declining paired server left a failed chat there while a first launch got
the server's terminal and a notice. The chat's Retry now hands the same
pre-create failures to the same replacement, carrying the prompt the
launch had staged.

* refactor(native-chat): a paired host's cancelled-chat record ends on its 30-day TTL

The paired census re-read a host's whole inventory after every
authoritative frame to retire tombstones, and a tombstone restored after
a reload needed a second such frame, so in practice it retired nothing.
A tombstone guards a random session id and is inert once stale; the chat
is already closed on its host whenever a frame shows it. The census, its
trigger in the mirror layer and its cleanup are removed; the owner-scoped
tombstones, close-on-sight, the TTL and publication marking from frames
stay.

* fix(native-chat): a chat's pane and status read from the host recorded on its tab

The chat pane and its sidebar status still derived the host from the
workspace id, which two hosts can share; a paired chat in a non-active
same-id workspace was read from this machine. Both now read the owner
stamped on the tab, as close, purge and publication already do.

* fix(native-chat): "Resume in chat" follows the terminal resume's host rule

Agent Session History offered "Resume in chat" for a conversation
recorded on this machine into a paired server's workspace, where its
transcript does not exist. A chat now resumes a conversation only on the
host that recorded it, as the terminal resume does, and that host is the
one asked whether it can resume history.

* fix(native-chat): the chat setting says older paired servers keep terminal chat

* test(native-chat): pin that a host advertises the client-chosen launch mode

* fix(native-chat): mirror this machine's chats only where it holds them

Round 1 ran the local chat mirror for everyone so existing chats show
whatever the setting says. That gave every desktop a permanent
session-tabs listener, which turns on the runtime's phone replication
paths, plus two full session-tab censuses at startup, and made the
browser client mirror its remote host a second time.

The runtime now says whether it holds structured chats: its structured
host is built only when saved chats were restored at startup or a client
created one here, and it announces the moment one is built. The mirror,
the startup restore and the continue-after-restart offer run only when
the setting launches chats or the host holds some, and never in the
browser client. A chat a paired client creates here with the setting off
still appears at once. The chat behaviour settings show wherever chats
exist, and the setting's copy says it picks what new agents open as. The
toggle-off teardown this made dead is removed.

* test(native-chat): route a paired-server launch over the capability lists both sides really advertise

* test(native-chat): record install listeners without a cast

* fix(native-chat): a paired server admits a chat before any of it exists here

The desktop opened a paired server's chat tab, launch record, queued
prompt and focus intent before asking the server, so a "no" needed a
replacement that undid and redid all of it, and every piece it missed
was a bug: the workspace deselected, the caller told "failed" while a
terminal ran its prompt, the caller's arguments and other queued prompts
lost, and a create whose reply was lost treated as never sent.

A paired launch now asks the server first and commits nothing until it
answers. Admitted opens the chat as before. Declined runs the caller's
own launch as the server's terminal, with the existing notice (a resume
fails instead, having no terminal equivalent). Unreachable opens nothing
and names the server in one toast. The new-tab launcher reports the
host's surface for paired workspaces, as it did before paired chats,
with the prompt delivery of whichever surface got the prompt. The
replacement and its error classes are gone, and the probe inside a
launch is back to its old meaning: a "no" is a failed chat with Retry,
and no answer leaves "Could not confirm" with Retry and the prompt kept,
here as on this machine.

* fix(native-chat): mirror this machine's chats only once it holds one, not once its host is built

Session history, resume preparation, terminal resume commands and replay-safe phone launches all
build the structured host for users who never had a chat, which turned on the chat mirror and the
structured-only settings rows until the next restart. The signal is now derived from the host's
records (or a records file still owed its import) and pushed when the first chat is restored or
created. A throwing listener no longer fails the install that fired it.

* fix(native-chat): a fork's reveal never seeds a terminal beside the surface the launcher opens

Forking into a paired-server workspace revealed it as if nothing would open there, so the reveal
created a blank host terminal beside the forked chat (and beside a forked agent terminal on main).
The launcher always opens the fork's surface itself, so the reveal now says so for every surface,
as the fix-checks launch already does.

* fix(native-chat): a declined direct launch keeps the caller's CLI args; an unreachable resume toasts once

When a paired server declines a "Fix checks" chat in a new workspace, the terminal that opens
instead now carries the recipe's saved CLI arguments, launch platform and launch source, as the
terminal route did. "Resume in chat" to a server that cannot be reached showed the admission's
"Could not reach" toast and the vault's generic one; the admission marks its failure notified and
the vault adds nothing.

* fix(native-chat): a declined background create opens its terminal without switching workspaces

Since #23974 a worktree create the user moved away from must not pull them onto the new
workspace. When a paired server declined that create's chat, the fallback terminal opened as a new
agent tab, whose host create selects the workspace. The create now opens its own agent terminal the
way main's background branch does: in place from the request's startup plan (so its CLI args carry),
without selecting the workspace. A create the user is still watching keeps the new-tab fallback.

* test(native-chat): name the launch's host in main's new outbox fence test

Main's new staging-failure test calls settleStructuredAgentLaunchPrompt without the target this PR
made required; it is a local launch, as in the sibling tests.

* fix(native-chat): a paired server's new chat shows no model until the server reports the one it started

A chat on a paired server starts with the server's saved model and options, but the picker showed
this desktop's saved selection (or the catalog default) until the server reported a model, and a
pick made in that window was remembered on the server under that guessed model. A paired launch
now carries no desktop seed, and until the server reports its model the picker names no model and
takes no picks. Local chats are unchanged.

* test(native-chat): seed the paired repo without a cast

The repo literal already satisfies Repo, so the changed-lines cast gate has nothing to excuse.

* feat(native-chat): createSupport reports the saved selection a new chat on this host starts with

A chat on a paired server starts with the server's saved model and options, which the desktop could
not read, so its picker showed a guess. createSupport's answer, which the desktop already waits for
before a paired launch, now also carries that seed as a new optional field (older clients ignore it).
Create and createSupport read it through one resolver so they cannot drift.

* fix(native-chat): a paired server's new chat shows the selection the server will start it with

The paired server now names its saved model and options in the admission answer the desktop
already waits for. That seed goes into the launch intent and its persisted record, so the picker
shows the server's model at once, stays pickable like a local chat, and remembers picks on the
server under that model; a reload shows the same. The locked picker remains only for a server too
old to name a seed.

Also moves host admission and launch-outcome tracking into their own modules: the latest main
merge left structured-agent-session-launch.ts over the max-lines limit.

* test(native-chat): expect the launch intent's new seed argument in exact-call assertions

* refactor(protocol): move the Electron remote client capability list into its own module

Merging main left protocol-version.ts one line over the max-lines limit on this branch. The list of
capabilities the desktop advertises to a paired host moves, unchanged, into
electron-remote-runtime-client-capabilities.ts, the module the next PR in the stack already uses
for it; importers point there.

* fix(native-chat): a paired chat with no saved server model is pickable; Retry shows the server's current seed

A server whose user never saved a chat model sends no seed, and the desktop showed a locked,
model-only picker for it, although that is the common case: no server that can admit a paired chat
predates the seed field. Such a chat now behaves like a local chat with no saved model: the CLI
default, pickable. The lock and its snapshot helper are gone.

Retry kept the first admission's seed while the create probe, which already runs on every attempt,
reported the server's current one and dropped it. The probe's seed now replaces a paired launch's
seed and the picker's, so a retried chat shows what its create will run.

* test(cross-version): stub the launch seed resolver createSupport now reads

* test(protocol): pin the desktop capability divergence against what a paired server receives

Every paired transport sends the shared remote base plus the Electron list, so the
divergence test now compares that union with the renderer's local list instead of
the declared Electron list. A capability added only to the shared base can no
longer slip past it. The two base-only capabilities it surfaced are recorded:
skills.install-result.v2 has no local caller; the authoritative-inventory label is
read by the local tabs sync but dropped by main, and is marked unsettled.

The turn-item and both background-task-stop capabilities were already sent through
the shared base, so the Electron list no longer repeats them. The wire set is
unchanged; this PR's real change on the wire is structured.v1, the Claude
structured capability and the client launch-mode capability.

* fix(native-chat): the route reads the capabilities a paired host actually receives

The renderer decided whether a paired host would admit a chat from the desktop's Electron list, but
every desktop transport sends that list plus the shared remote base. They agreed only because the
route's checks happened to sit in both. The route input is now built with the same
remoteRuntimeClientCapabilities the transports use (the browser client already sends its list as is),

* fix(packaging): ship serve-sim only in macOS builds (#25128)

serve-sim drives the iOS Simulator, which exists only on macOS. Since 0.1.47
(#24228) it carries a Mach-O addon, and Windows signing rejects every *.node
that is not a PE file, so the v1.4.220 Windows build failed at SignPath.

Adapted from @akhan157's OpenCode native history work in #13287 at bb661d10d716764fb472d824cd434678875b1947; retains the current bounded reader and account discovery instead of restoring the older capture and cursor implementation.

* fix(native-chat): keep split OpenCode rows intact on desktop and mobile

Preserve the native reader's bounded OpenCode row groups in paired reads and snapshot/replacement frames so a second presentation-count slice cannot drop reasoning while advancing the database cursor. Sort derived reasoning before its answer under the same provider timestamp while retaining journal order.

These two boundaries were reproduced with genuine installed 2.0.16 and official 1.18.30 sessions in a hidden desktop renderer and the current mobile view over an actual authenticated encrypted pairing.

Completes the semantic presentation from @akhan157's #13287 without importing its older clipping or cursor implementation.

* ci: run the cross-version tests when the chat send builders or the RPC request path change (#25061)

* ci: run cross-version wire suites when agent sends or orchestration change

The selector skipped the cross-version wire job for #24901, which changed the
shared agent-send path, the structured send envelope builders, and orchestration
RPC code. Route the send payload/fingerprint builders, src/main/runtime/orchestration/,
and the orchestration RPC methods to the job, and pin each rule in a test.

* ci: run cross-version wire suites only for code they execute

The agent-session suites now build their send through the shared outbox
builder and check it against the release host's schema and fingerprint,
so the send builder and outbox are selected exactly. Load-only
orchestration rules are dropped; the dispatcher-path files every suite
request runs through are selected instead.

Marking a folder trusted for Copilot rewrote ~/.copilot/config.json through a
temp file created with the default umask mode (usually 0644), so an owner-only
file that can hold copilotTokens became readable by other local users. Since
the folder-trust change this write also runs on SSH hosts, where other users
exist. The rewrite now always writes the file owner-only (0600).

* feat(codex): tell Windows users once that Codex in Orca now shares ~/.codex (#24916)

* feat(codex): tell Windows users once what stays behind when Codex moves onto ~/.codex

When Windows' system-default Codex first runs on ~/.codex (launch prep or
the usage poll), main decides once whether Orca's managed home was ever
used and which MCP servers lived only there, and persists that in UI
state. The renderer shows one dismissible toast when a Codex terminal
exists, after the server-isolation notice rather than on top of it, and
clears the notice when shown.

The "kept only in the managed home" MCP rule is extracted into
isRuntimeOnlyMcpServer, which the config mirror merge now uses too, so
the notice names exactly the servers the mirror would have kept.

* fix(codex): stop counting Orca's own config.toml as use of the old Codex home

Orca's hook install writes that home's config.toml on every startup, so its
presence was true for nearly every Windows user with Codex. The home now
counts as used only with recorded sessions or an MCP server of its own.
Resolver tests keep one case per input source.

* refactor(codex): ask main for the shared-settings notice instead of persisting it

The persisted missing/object/null field, written from launch prep and the
usage poll, becomes a plain codexSharedSettingsNoticeSeen flag mirroring
codexTerminalServerIsolationNoticeSeen. When a Codex terminal first appears
and the flag is unset, the renderer asks codexConfigSync:sharedSettingsNotice
once; main answers read-only (Windows, system default on ~/.codex, managed
home path without mkdir) and maps any read error to null.

Runtime-home routing, launch and the test harness return to main's code.
The notice no longer waits for the server-isolation toast; they may stack.
The Codex-terminal watch moves to codex-terminal-presence.ts.

* refactor(codex): watch for the first Codex terminal in one place for both notices

The server-isolation notice now passes its due check to
whenCodexTerminalAppears instead of keeping its own copy of the presence
scan, input filter and subscription loop. Its behaviour and tests are
unchanged.

* docs(codex): trim isRuntimeOnlyMcpServer's comment to why it is shared

* refactor(codex): keep McpServerTomlOwnership private to its module

* test(codex): cover the shared-settings notice channel without type assertions

Handlers are looked up by channel now that two are registered, so the
status tests no longer depend on registration order.

* refactor(codex): show the Windows shared-settings notice without asking main

Every way of detecting who relied on Orca's old Codex folder had false
positives, so the renderer now shows one static toast on Windows the first
time a Codex terminal exists. This drops the main-process resolver, its IPC
channel, preload line, web stub and shared type, and the MCP-names variant
of the description.

* refactor(codex): restore the MCP server ownership helpers to main's shape

The static notice no longer reads MCP servers, so the shared
isRuntimeOnlyMcpServer extraction has no second caller.

* refactor(codex): let each notice decide when it is due, so the Codex watcher only watches

The isolation notice now selects its due predicate and starts the watcher only while due, so whenCodexTerminalAppears no longer takes an isDue or re-checks hydration and settings. The shared-settings notice uses isLocalWindowsDesktopClient, its test stubs the user agent instead of mocking pane-helpers, and the hydration safeguard it relies on is now tested on the UI slice itself.

* test(codex): drive the Codex notices through a reactive store, and drop a redundant hydration gate

The server-isolation notice now reads "is it due" through a store selector, but its test
mocked the store without re-rendering, so a due change after mount (persisted UI loading,
the setting turning off) was never exercised. The notice tests now share one harness backed
by a real zustand store, the shared watcher gets its own test, and both notices cover the
seen flag loading after mount.

persistedUIReady is dropped from isNoticeDue: the seen flag defaults to true and only
hydration clears it, in the same update that sets persistedUIReady. Both notices now gate
the same way.

* fix(codex): keep the shared-settings toast until dismissed, and shorten it

It is marked seen before it shows, so a 15s auto-close could lose it for good while the user
is typing in the Codex terminal that triggered it. Every other one-shot notice that marks
itself seen on show stays until dismissed; this now does too.

The text drops the sentence that repeated the title and keeps only what to expect and do.

* fix(codex): keep Orca-only MCP servers when refreshing the retained shared home

The refresh for panes that outlive an update treated the old shared
home's whole MCP root as owned by ~/.codex, so it deleted servers the
user had added from an Orca terminal, which existed only there. Read the
home's settings baseline instead, as the normal mirror does: drop only
servers the last mirror copied from ~/.codex. No baseline keeps the old
behaviour; an unreadable one skips the refresh. The baseline is not
advanced, keeping the refresh one-way.

* A resent chat message gets its recorded answer, never an early refusal or a made-up record (#25158)

* fix(native-chat): a resent send id gets its recorded answer, never an early refusal or a made-up record

The host now looks a resent send id up before preparing the session. A row
that settled refused answers with its refusal before the chat is opened. A
resend whose chat cannot be opened or made ready answers unknown instead of a
refusal. A /clear in flight refuses only ids the ledger does not hold.

A send row now records the journal epoch it was admitted into. An unsettled
row with nothing written in that same epoch runs for the first time; under a
later epoch the host answers unknown instead of reconstructing a submission
it never had. The host advertises agent-session.send-answers-proof.v1.

* test(native-chat): pass the ledger row to the thread-goal rerun check

* fix(native-chat): a send's answer commits with its write, and a resend is answered before any write

A send (and /compact) settles its ledger row `succeeded` in the same SQLite transaction as the
submission or queued draft that accepts it, so a row still `pending` proves nothing was written and
a resend runs it for the first time. The unknown-before-run mark and the per-row journal epoch go.

A resent id is answered from its row and the journal before preparation starts an agent and before
any write transaction: a recorded refusal with nothing opened; otherwise the conversation is opened
(no agent start for a send) and replayed, and a conversation that will not open answers unknown.

* fix(native-chat): a ledger refusal is answered first, and a /clear refuses only a send's first run

An id the ledger refuses (expired, conflict, invalid, capacity) is answered as admission would,
with no journal read, preparation or write, so a closed chat or a read-only store answers it too.
A re-read after the replay open that comes back refused returns that refusal.

Whether a /clear is in flight is read when a send arrives and applied in the send's preparation
for a first run only: an id the ledger holds by the send's turn, including one whose earlier
attempt was queued ahead of the clear, is answered from its record. MutationPlan makes
settlesWithWrite and settledOutcome exclusive; the capability text no longer promises a refused
id never sends.

* fix(native-chat): show a message Orca accepted and then failed to deliver as "Not sent" in the chat (#24710)

* fix(native-chat): keep a message the host accepted then rejected in the desktop chat as not sent

Draw it in place from the host's history, so a crash that loses the outbox no
longer makes it vanish. A later copy of the same body supersedes it; the outbox
row wins while it holds the message; the phone is unchanged.

* test(native-chat): pin the same-id rule apart from the body match

* test(native-chat): type the rejected-in-place fixture body as a text block

* fix(native-chat): let the host's row own a message it recorded and then rejected

Once the host's journal records a send as rejected, the desktop outbox lets it
go, as it already does for delivered and Stop-withdrawn sends: the host's row
shows it as not sent, with the host's reason and no Retry. The outbox keeps
only sends the host refused before recording them, which keep their Retry.
A send whose own reply says it was rejected is drawn by its outbox entry, with
no Retry, until the journal carries the row; a copy left by an earlier session
is dropped when the chat opens.

- the transcript no longer hides a host row behind an outbox entry with the
  same id or the same text; those rules and their cache are gone
- a rejected message the queue holds (a draft's hand-off, or a live card under
  its id) is drawn as its card, not as a row
- a later copy of the same text hides a rejected row only when it was sent
  once the rejection was known, so a deliberate repeat stays
- delivery notices read the same visibility rule as the transcript; a chat
  whose only rejection a Stop withdrew no longer rebuilds them per batch
- the body fingerprint helper goes back to the host, its only user

* test(native-chat): keep one row when copies of a rejected message share an instant

* refactor(native-chat): let the host's notice replace the outbox's under the same id

* test(native-chat): pass the queued card ids in the tool-stream cost transcript

* fix(native-chat): keep the host's record as what lets a rejected message go

- the outbox no longer drops a host-rejected message when a chat opens; the
  reconcile lets it go once the journal's submissions say it was rejected, and
  that drop is written to storage, so nothing reads as still owed
- a message the host rejected while the chat watched waits for its journal row
  with no Retry; one read back from storage with no row loaded keeps its Retry
  under a new id, since the host may have lost it
- the delivery notices keep the same map and notice objects across a batch that
  words every row the same, so a submission batch re-renders no row
- a rejected command such as /compact stays hidden: its own reply reports it
- the desktop transcript requires the queued card ids, with a controller-level
  test that a card holding a rejected message keeps its row hidden

* fix(native-chat): draw a queued message where the host rejected it

A message accepted to hand over later and rejected before any handover now sits
at its rejection, as a handover places one: what the agent did while it waited
happened before it, and the newest history page holds it. One handed over, or
dispatched as it was recorded, keeps its place. An older host does not move it,
so it stays at its submission, still drawn.

A failed start now rejects the queued messages and writes its row in ONE
journal append, the messages first: no reader ever meets one without the
other, and the messages still draw above the row that says why.

* test(native-chat): pin that rows written together roll back together

* fix(native-chat): draw every rejected message where it was rejected

Not only a queued message: one handed over into a turn and then rejected, or
sent directly and rejected, also sits at its rejection, in no turn. A message
in doubt stays where it was, a plain bubble: it may have reached the agent.

* fix(native-chat): decide a rejected message's Retry from the host's stored fact

- a message the host recorded and then rejected has no Retry on any mount,
  however that mount learned of it, and a Dismiss that clears it from storage;
  a send refused before the host recorded it keeps its Retry
- the rule that keeps a rejected command such as /compact out of the
  transcript moves into the one visibility function rows and notices share
- the outbox state docs say what lets a recorded message go: the client holding
  its rejected submission, whose row the host places at the rejection

* fix(native-chat): write no start-failure row when a Stop withdrew every queued message first

* test(native-chat): pass the Dismiss action in the delivery-notice hook tests

* fix(native-chat): keep a rejected message's outbox copy until its row loads

An older host leaves a rejected message where it was sent, which may be older
than the loaded window: the chat then holds the rejected submission but not the
row that draws it. The outbox copy now stays until that row loads, marked as
the host recorded it (Dismiss, no Retry, in the host's words), and leaves once
the page holding the row is loaded. Derived from the loaded rows each time.

Tests that label their projection as the phone's now pass the phone's own
setting.

* test(native-chat): type the outbox hook props that carry loaded rows

* fix(native-chat): write nothing when a journal batch settles nothing in the outbox

The outbox re-reads the journal on every batch since it waits for a rejected
message's row to load. Its reconcile now returns each unchanged entry, and the
list, as themselves (a message left in doubt included), so a batch that changes
nothing writes nothing to storage. The reconcile moves to its own module.

A copy the host recorded and rejected owes no delivery, so it no longer keeps a
hidden pane reading the journal.

* test(native-chat): count storage writes on the outbox's own storage object

* fix(native-chat): let a recorded rejected message's outbox copy leave on its own, with no Dismiss

The outbox copy of a message the host recorded and then rejected draws it only
while the host's row is not loaded, and leaves on the batch or page that loads
that row. It owes no delivery and offers no control: sending it again is a new
message. The Dismiss that let the user clear it is gone, from the outbox, the
notices and the session controller.

* Add shared workspace settings note and prevent filter modal expansion (#25300)

* fix(mobile): say that workspace sort, grouping, and filters are shared

The Manual sort option was subtitled 'Server order', but it orders by the
desktop's drag ranks. Sort, grouping, and filters on the phone all write the
host's shared view settings, so changing them also changes every other
device on that host, which the screen never said. Relabel Manual as 'Desktop
drag order' and add 'Shared with other devices on this host' under the Sort
By, Group By, and Filter titles. The note avoids naming a desktop sidebar
because headless hosts have none.

* fix(mobile): prevent filter modal heading expansion

* update wording

* fix(native-chat): a new structured chat's model list comes from the machine that runs it (#25143)

* fix(native-chat): a new structured chat's model list comes from the host that runs it

agentSession.modelCatalog builds the structured-session host like agentSession.options,
so a host with no saved chats since it started answers instead of refusing. When the
host answers unknown because its first listing runs in the background, the picker
re-reads on a bounded schedule until that listing lands. Local terminal-backed chat
skips the structured catalog when a custom launch command is configured.

* fix(native-chat): wait on the host's first model listing instead of re-reading on a timer

A new structured chat's picker read the host catalog once; on an account the
host had never listed, the answer was "unknown" while a background listing ran,
and the client re-read on a 1-30 s schedule. Replace the schedule with the
host's own completion signal:

- The host answers a cold read with `listingInProgress: true` (new optional
  field) once it has started or joined that listing. A read that passes the new
  optional `waitForListing` param awaits the same joined listing and answers
  with it, or a plain "unknown" if it failed. The at-rest options read never
  waits. A host that predates the field never sends it, so the client never
  sends the param to a host that would refuse it.
- The picker reads once per open and attach; after the host's report it sends
  one waiting read, with a 90 s client timeout above the slowest listing.
  While that read is out, the model pill keeps its label but cannot open or be
  set (typed /model included). An answer, failure, timeout, hide, attach or
  the provider's own list releases it.
- `agentSession.modelCatalog` builds the structured-session host only for a
  read that names a session (a structured chat). Terminal-backed chat's
  session-less read keeps the non-building gate, so a desktop that never runs
  structured chat never opens the session journal.

* fix(native-chat): one waiting model-list read per chat, and no late menu open

The waiting catalog read was owned by one run of the picker's effect. Attach
(a new fence), hide/show or a send re-ran the effect: the cleanup released the
model picker onto the built-in list for a round trip, and the new run sent a
second waiting read while the first, which cannot be withdrawn, kept a remote
call slot until the listing ended.

The waiting read now belongs to the chat (runtime target + agent + session):
a small registry keeps one in flight per chat, every re-run or remount joins
it, and the entry is deleted when the read settles. The picker hold is derived
from that entry being in flight, so it lasts across attach and hide/show and
ends when the read settles, the provider reports its own list, or the pane
switches to another session. Answers still pass the stale and record checks.

A bare /model typed while the list loads no longer opens the model menu by
itself when the list lands: the menu stays keyed on the request, and only its
initial open is suppressed while pending, so the request is spent shut and the
end of the pending period never remounts it.

* fix(native-chat): release the model picker in the same commit as the host list

When the waiting catalog read settled in the chat that started it, the
registry dropped its entry and told subscribers first, and the host list was
applied a few microtasks later. React committed once with the picker enabled
on the built-in list, then again with the host's list.

Joiners now hand the registry their apply callback, and the registry runs
every joiner (with the answer, or nothing when the read failed or timed out)
before it deletes the entry and notifies. The release and the list land in one
commit. An effect cleanup leaves the wait instead of flagging itself stale.

* fix(runtime): queue model catalog reads in the long-wait lane

A model catalog read that waits on a host's first listing replies only when
that listing ends, yet it took one of the 8 foreground call slots for its
server. Enough chats opened during one cold listing would stall that server's
sends and interrupts until a wait settled.

agentSession.modelCatalog now joins worktree.rm in the long-wait lane: same
concurrency, counted apart from the foreground calls. The queue classifies by
method only, and a warm catalog read answers at once, so the whole method
moves.

* Fix: settle sortEpoch in store to prevent React update depth exceeded (#25313)

* fix(sidebar): stop Manual sort from mirroring sortEpoch into state

In Manual mode the sort hook copied every sortEpoch bump into state from an
effect, adding a nested React update per bump. A burst of store bumps at
startup stacked those into 'Maximum update depth exceeded' (React #185).
Manual now reads the live epoch directly; debounced modes are unchanged.

* feat(sidebar): tell people when a drop switches sort to Manual

Reordering by drag still switches the sidebar to Manual so the drop sticks,
but it used to happen silently. Show a toast with a 'Back to <previous sort>'
action; it retires itself on any later sort change so it can't override a
newer choice. Drops while already in Manual stay silent.

* feat(store): settle sortEpoch in the store instead of in React state

Add settledSortEpoch plus a 3 s settle timer owned by a store listener
installed in the state creator. Every write path (slice actions, the web
session sync patch) goes through it, so the settled value stays correct
with no sidebar mounted. Manual, a sort-mode switch, and a bump that
changes the non-archived row count settle in the same notify; other bumps
restart the window. A reset that lands settled clears the timer, and the
disposer runs on HMR teardown.

* fix(sidebar): read the settled sort epoch instead of mirroring it into state

The sort hook no longer copies sortEpoch into React state from an effect in
any mode; it reads the store's settledSortEpoch directly. That pattern added
a nested update per bump and stacked into "Maximum update depth exceeded"
(React #185) under flushSync bursts. Tests cover Manual, add/remove, burst
reset, no-bump row changes, mode switch, and 80 flushSync bumps in Recent
while worktrees are added.

* fix(terminal): stop old output bleeding into Claude's screen when revisiting a remote tab (#24926)

* fix(terminal): leave the alt screen before replaying a pushed host snapshot

A remote terminal running a full-screen agent (Claude Code) could show old
output (e.g. a setup script's pnpm log) interleaved with the agent's screen
after switching back to the tab. The host's pushed snapshot is a serialized
image that starts on the normal buffer and enters the alternate screen
itself, but the replay drain cleared with ESC[2J without leaving alt. The
image's history painted into the agent's screen, its own ?1049h was a no-op,
and the agent's diff paints landed on top of the stale cells.

The remote-runtime transport now marks snapshots as serialized images, and
the drain grounds them with the shared snapshot prologue (switching to the
normal buffer first). Raw byte replays (SSH relay ring buffers) keep the
in-place clear.

* fix(terminal): paint folded remote snapshots from the normal buffer everywhere

Review follow-ups:
- Rename the flag to carriesNormalBuffer: what the painters rely on is that
  the image starts on the normal buffer and enters alt itself.
- Hidden-output restore had the same bug for remote requested snapshots
  (history folded into data, alternateScreen set): the painter entered alt
  first and painted the normal buffer into the TUI's screen. Requested remote
  snapshots now carry the flag and take the normal-buffer start.
- Flag pushed snapshots replayed after a cancelled shutdown too.
- Pushed snapshots carry only the screen, so over a live TUI the drain keeps
  the normal-buffer history it covers instead of wiping it.
- Read the pane's buffer after queued output parses.
- Tests compare whole buffers against a fresh terminal, use production image
  shapes, and pin the raw-replay path with the same oracle.

* fix(terminal): let the replay drain own the recovery snapshot clear

The recovery prefix's own \x1b[3J ran after the drain's prologue and wiped the
history the drain keeps under a live TUI. Keep only the latch release, which
still makes an empty recovery snapshot non-empty so it is applied.

* fix(terminal): keep the recovery snapshot's own screen clear

Consumers that write recovery snapshots straight into xterm (no replay drain)
rely on the prefix clearing the stale screen. Restore \x1b[2J\x1b[H and drop
only \x1b[3J, which wiped history the image does not carry.

* test(terminal): drive the drain with the real recovery payload

The multiplexer prepends its own screen clear; replaying that exact payload
pins that the prefix cannot wipe the history a TUI covers.

* fix(terminal): keep TUI-covered history only when the grids match

Second review follow-ups:
- A pushed image carries only the host's screen; the pane's frozen history
  continues it exactly only on the same grid. On another grid keeping it
  duplicated or dropped lines, so the image replaces it there.
- Tests replay the pane's writes and grid changes into a real terminal and
  compare whole buffers with the host, including a mismatched-grid case.
- The split branch shares the normal-buffer preamble; drop the now
  single-use abort helper.
- Type serializeBuffer as RemoteRuntimeSnapshotImage so the flag is carried
  by type, not by object pass-through.
- Register the grid and raw-replay cases in the reliability gate.

* fix(terminal): keep TUI-covered history only while the host is still on alt

The drain kept the pane's history whenever the pane was on the alt screen. If
the host's TUI exited while the tab was hidden, the shell wrote past that
history and the kept lines no longer continued the host's screen. Require the
host's own alternateScreen too; an absent flag proves nothing, so the image
replaces history as on main.

Also: one buildSnapshotReplayPreamble for every first replay write, the drain's
image and raw clears as separate branches (raw byte-identical to main, comment
restored), and a single paneAtSourceGrid check.

* fix(terminal): gate kept history on the host's shell-owner proof

The host sends alternateScreen only with terminalOwner 'shell', i.e. once it has
proven the TUI exited, so `alternateScreen === true` never held for a live TUI
and the drain wiped the history it should keep. Replace the history only once
the host proves the TUI exited; tests now use production snapshot shapes. Move
the relay-overlap comment into the raw-replay branch it describes.

* fix(terminal): keep TUI-covered history only on a proven shared grid

An image without its grid cannot prove the pane's history continues its screen,
so it now replaces history. Also update a stale recovery-prefix test comment.

* test(terminal): replay host-serialized snapshots through the real wire and drain

Hand-written replay meta hid a gate that production never satisfies. Drive the
host's own emulator, ownership mirror, serializer and recovery publisher through
the real wire, client parser, remote transport and pane drain, for a live TUI
and after the host proves it exited.

* fix(terminal): repaint only the alt frame over a live TUI, leaving history alone

Keeping the pane's history by clearing only the normal screen assumed a pushed
image carries no history, which the host does not guarantee: a 0-row push can
reuse a concurrent requested capture, and its history then landed twice in
scrollback. It also wiped history on a grid mismatch, where main kept it.

When pane and image are both on alt, the image's normal part adds nothing (the
normal buffers froze together), so paint only its alt payload after an alt-side
clear, split at the host's own boundary (splitAtAlternateScreenEntry, now shared
with the daemon). Any other image paints from the normal buffer. This drops
keepScrollback, the owner and grid gates, and the recovery-prefix change, so
history behaves exactly as on main.

* test(terminal): pin the parse wait and the cancelled-shutdown flag

Final-review follow-ups: a drain test where the TUI's ?1049h is still queued
when the image arrives, and a transport test replaying a push buffered during a
cancelled shutdown; each fails when its guard is removed. The requested-image
test now names the exited-TUI case it covers, requestSnapshot shares the
snapshot image type, and the clear comment no longer implies every clear drops
scrollback.

* fix(native-chat): show "Sending…" on a message until the host confirms it (#24606)

* fix(native-chat): no "unconfirmed" line while Orca resends a send on its own

A send whose answer was lost (for example after reopening the chat mid-send)
showed "Message delivery is unconfirmed." with a Retry for the moment before
the automatic resend under the same message id confirmed it. One rule now
decides both: the resend runs, and the notice stays quiet, only while the
send's answer is lost, the user never retried it, it was not still going out
when the user pressed Stop, and the host has no record of it yet. Once the
host has any record of it, the line and Retry are exactly as before.

* fix(native-chat): say "Sending…" on a message until the host confirms it

A send whose answer was lost was resent quietly under the same id but looked
like any delivered message. Every message still in the outbox with no failure
to show now says "Sending…", muted, in place of its time, until the journal
holds a row for it. Rows that say a message did not go through keep only that
line and its Retry. The notices read the outbox through the same reconcile as
the transcript, so a row that lands clears the marker in one step.

* fix(native-chat): keep "Sending…" until the host has the message, in the time's slot

A message the user retried, a second message in doubt, or one requeued over a
rejected row had a journal row that did not hold it, so it showed nothing and
looked sent. "Sending…" now stays until the row is pending or accepted.

The marker took the place of the whole meta row, so the copy button went away
while sending and the row jumped when it cleared. The row now stays mounted:
copy keeps its hover reveal and "Sending…" sits where the time goes.

* test(native-chat): move the delivery probe tests into their own file

NativeChatStructuredSessionDelivery.test.tsx went over the 800-line lint
limit after main was merged. The eight tests for the automatic probe of an
unconfirmed message move unchanged to
NativeChatStructuredSessionDelivery.probe.test.tsx, which uses the shared
structured-session test harness for its mocks. The outbox seeding and probe
clock helpers move into that harness so both files share them.

The at-most-once reliability gate now lists the new file, with a fresh
evidence run.

* Tighten spacing in workspace deletion confirmations

* Address deletion dialog review and synchronize localization catalogs

* fix(editor): restored tabs for files outside your projects no longer fail with Access denied (#24489)

* fix(editor): read files outside projects without a grant a restart loses

A file opened from outside every project (e.g. ~/notes.txt from the floating
workspace) read through an in-memory grant. After a restart the restored tab
only renewed that grant when it stored a full path, so a tab saved relative to
the floating workspace folder failed with "Access denied" and Retry repeated it.

Single-file reads (read, stat, exists) and open-editor-tab saves now resolve a
path outside every project in place. Paths inside a project keep the full
containment check, so a project's symlinks still cannot escape it, and every
other write stays inside projects.

* fix(editor): re-grant restored floating-workspace tabs by owner, not path shape

Problem: a file opened from the floating workspace (e.g. ~/notes.txt via
Cmd-click in the floating terminal, the floating markdown picker, or a .md
opened from the OS) loads until restart, then shows "Access denied: path
resolves outside allowed directories". Main's external-path grants live only
in memory. On restore the editor re-granted only tabs that stored an absolute
path, but floating tabs store a path relative to the floating root (~ by
default), which is deliberately not an authorized root, so they were never
re-granted. Restored floating notebooks also failed to start a kernel.

The previous commit on this branch let main read and save any path outside a
project without a grant. That widened fs:readFile/stat/pathExists for every
caller, including automatic reads of untrusted content (markdown preview
images), which opened a Windows UNC credential leak and a /dev/zero
main-process memory blowup. This reverts that model entirely.

Fix: one helper decides which client-local path a tab needs re-granted by
ownership: a floating-workspace tab, or a tab stored outside its own project.
It never grants paths a local project root covers (a grant would also
authorize a project symlink's outside target), and skips SSH-owned,
runtime-owned and not-yet-hydrated owners. Every reader that can touch a
restored tab before or without the editor loader uses it: the loader, the
restored dirty-tab conflict scan, and the paired-mobile markdown bridge.

* fix(editor): let main decide which restored-tab paths a project already covers

Problem: the restore re-grant helper decided "already inside a project" in
the renderer from its worktree list. At startup that list only holds repos
the session references, so a floating tab inside an unlisted repo was granted
(including a symlink's outside target), and the renderer's path matcher
disagrees with main's on WSL \\wsl$ vs \\wsl.localhost, which stranded a
folder-workspace tab with "Access denied" after restart. The helper also
treated a folder workspace with a missing or ambiguous host as local.

Fix: the renderer now decides only by owner (a floating-workspace tab, or a
tab stored outside a project whose owner is explicitly local) and asks main
with `skipIfInsideAllowedRoots`. Main checks the path against its own allowed
and registered roots, in both the named and canonical-parent spelling against
both root spellings: a path a project covers gets no grant, an alias spelling
of a project path gets only that spelling, and a project symlink's outside
target is never granted. Explicit-open grants (Cmd-click, drag, explorer) are
unchanged. Tests now prove each reader waits for the grant before reading.

* fix(fs): decide a restored tab's project membership from every ancestor's real path

Problem: the restore re-grant decided "inside a project" from the named path
and the real path of its parent only. When a tab path crossed a project
directory symlink and named the project through a spelling that was neither
the registered root nor its realpath (a second alias, a `..` segment, a case
variant on a case-insensitive disk, a /var-style alias of an ancestor), no
check matched, the path took the full grant, and the symlink's outside target
became readable and writable.

Fix: a path is inside a project when the named path is inside a root, or the
real path of any ancestor folder is inside a root in its registered or real
spelling. Such a path gets at most its named spelling, never its realpath. An
ancestor that fails to resolve for any reason other than "missing" now fails
closed to the named-spelling grant instead of falling through to the full one.
Tests cover each spelling; the non-symlink case also runs on Windows.

* fix(fs): read local files as regular files only, from one bounded handle

Problem: fs:readFile stat'ed a path and then read it to EOF. A character
device such as /dev/zero reports size 0, passes the size limit and never ends,
so the main process buffers until memory runs out; a FIFO hangs the open.
Writes could also target an existing device or FIFO.

Fix: every local fs:readFile (editor and log snapshot) opens the path once,
non-blocking, refuses anything but a regular file, and reads the size check,
binary probe and content from that same handle, capped at the limit even if
the file lies about its size. The AI Vault log tail opens non-blocking too,
and fs:writeFile refuses an existing non-regular target.

* feat(fs): let desktop file requests declare their shape

Problem: main decided every local file request against one allow-list plus a
set of in-memory grants the renderer had to recreate after every restart, so
a file the user opened outside a project (for example from the floating
workspace) was denied once Orca restarted.

This adds the request shape the common pattern uses, alongside the grants for
now:
- no shape (the default): the path must be inside a project root main
  recognises, symlinks included. Desktop requests also accept the app-owned
  floating-workspace folder; paired-client RPC never does.
- user-file: a single file the user named by absolute path, used in place.
  Only fs:readFile/stat/pathExists and saving (fs:writeFile) accept it.
- document-resource: an image or PDF a document references, limited to every
  project root when the document is in one, else to the document's folder,
  and refused by path text before any disk or network access.
Notebook kernels and AI Vault log tails check their open file as user-named.

* feat(editor): send each local file request's shape from the renderer

Problem: after a restart, a tab opened outside every project (a floating
workspace file, a file opened by absolute path, an OS-opened markdown) could
only be read if the renderer first re-granted its path, and readers that ran
before the editor loaded the tab had no grant at all.

The renderer now says what kind of request it is making, and main checks that:
- A persisted tab opened outside its owner's root (floating workspace, or an
  absolute stored path) whose owner is explicitly local reads and saves as a
  user-named file, from every reader: the editor loader, the restored-tab
  conflict scan, the change banner and compare dialog, the paired-phone
  markdown bridge and the save queue. Project tabs stay inside their root.
- Clicks, drops, typed paths and browser-opened notebooks stat as user-named.
- Markdown preview and rich-editor images are document resources, limited to
  the document's roots or folder. Images the user pasted or attached into a
  chat show as user-named; agent images stay inside the project.
- The image cache keys on the shape, so one shape's image never answers
  another's request.
A ratchet test lists every renderer file allowed to create a user-named
request.

* refactor(fs): delete the in-memory path grant system

Problem: main kept a set of paths the renderer had asked it to allow
(fs:authorizeExternalPath). The set lived only in memory, so a file the user
opened outside every project could be read until Orca restarted and was then
denied, and every new reader of a restored tab had to remember to recreate
the grant first. Three rounds of re-deriving grants at restore each found
another reader or path spelling it missed.

Now that every desktop request declares its shape, nothing needs a grant:
- delete the grant set, authorizeExternalPath, the restore re-grant from the
  earlier commits on this branch, the fs:authorizeExternalPath channel and its
  preload and web-client entries;
- delete every renderer grant call (terminal and markdown link clicks, drops,
  typed paths, the file explorer, AI Vault logs, chat attachments, browser
  notebooks) and every main one (floating markdown picker and folder, OS-opened
  markdown, keybindings.json, pasted images, import and upload sources);
- the floating workspace's picker-approved folders stay a terminal-cwd
  allowlist only.
Main now holds no per-path permission, so a restart can't change any answer.

* feat(editor): open project links that lead outside the project as named files

Problem: a file inside a project that is a symlink to something outside it
opened fine from the file explorer or a terminal Cmd-click, then showed
"Access denied" after a restart: its tab was stored as a project file, and a
project request is refused when it resolves out of the project. A folder link
out of the project expanded in the explorer until restart and then failed with
a raw access error.

Now the click decides and the tab keeps that decision. Both gestures stat the
path inside the project first; if only the user-named check passes, the path
leads out of the project:
- a file opens by its absolute path, so it reads and saves as a file the user
  named, the same before and after a restart;
- the explorer does not follow a folder link out of the project and says so
  ("This folder links outside the project, so it can't be opened here.").
Paths that stay inside the project still open as contained project tabs. Also
drops the AI Vault "path not authorized" message, which nothing shows now.

* chore: drop the casts the changed-code quality gate flags on this branch

The FileContent casts in the editor loader and the paired-phone markdown
bridge were never needed (the read result is already assignable). Tests stub
window.api through vi.stubGlobal and pass narrow stores without casting; the
one test store that still needs a cast states why.

* fix(fs): load chat images by type, and keep escaping project links readable

Problems found in review:
- Chat transcript images were trusted by message role: any user-role
  "[Image: source: <path>]" (an injected Claude record, `orca terminal send`,
  a paired client's image-ref) became an automatic user-named read as the row
  scrolled into view, of any file type, and on Windows a network-share path
  would have opened an SMB connection to that host.
- A document image named like an image but linking to a text file
  (logo.png -> .env) was read as text.
- Windows device names (NUL.png, COM1.jpg) passed the path-text check of the
  automatic image loads.
- A project symlink leading out of the project, opened by a typed path, a
  tab-strip drop or a browser file:// notebook, was stored as a project tab
  and immediately refused.

Fix:
- New chat-image request shape for every transcript image and the composer
  preview, whoever's turn named it: an absolute local path whose requested and
  real targets are image files, a regular file, size-capped; network-share and
  device-namespace paths and Windows device names are refused by path text
  before any filesystem call. Pasted screenshots still show after a restart,
  and agent images outside the project now render.
- Document resources check the real target's type too, and refuse Windows
  device names by path text.
- Typed paths, tab-strip drops and browser notebooks stat through the same
  check as the explorer and terminal, and open an escaping link by its
  absolute path.
- Tests pin the shape at the change banner, compare dialog, markdown preview
  and image prewarm; a second ratchet lists every file that can open a tab the
  tab rule reads as user-named, and its comment says what it can't see.
- Stale grant wording removed.

* fix(fs): tighten automatic image loads and the project-link check

Problems found in review:
- Two unit tests went red on this branch: the browser-share test still
  expected reads without a shape, and the rename test's electron mock had no
  app, which the desktop root check now needs.
- The device-name check ran on the raw path, so `NUL.png\.` or
  `COM1.png\x\..` (reachable from markdown `![](NUL.png%2F.)`) reached the
  filesystem; a document image whose real target was a device name passed.
- Chat images in a project that lives on a Windows network share no longer
  rendered, though the markdown preview showed them.
- Any failed project check (a missing file, a dropped connection) was taken
  as "this link leads out of the project" and opened as an absolute tab.
- Every local read allocated about 2 MiB, even for a tiny image.

Fix:
- Device names and device-namespace paths are checked on the resolved path
  and on the real target, for chat images and document resources alike.
- A network-share path in an automatic load is read only inside a project
  root (the user chose that share when adding the project); anywhere else it
  is still refused by path text before any filesystem call.
- Only main's "outside allowed directories" refusal marks a project path as
  leading out of the project; other errors surface as before. The message now
  lives in shared code so both sides agree on it.
- Reads size their first buffer from fstat and confirm EOF with a 1-byte
  probe; a file that grows past its reported size is still read in bounded
  chunks up to the cap.
- Fixed the two red tests.

* refactor(fs): name file access by its role, not its structure

Problem: the static-analysis anti-slop check failed the PR because the new
code named the request's file access a "shape" (`shape`, `RequestShape`,
`TabShape`), which describes structure rather than the role.

Rename the main-process module filesystem-request-shape.ts (and its tests) to
local-file-access-resolution.ts, rename the symbols to fileAccess,
FileAccessResolution and TabFileAccessFields, and say "file access" or
"access kind" in the comments and test names. No behaviour change.

* fix(fs): refuse every Windows device-name spelling in automatic image loads

Problem: the device-name check split a file name only on '.', so names such
as NUL:.png, COM1:.png, NUL:stream.png (an alternate data stream) slipped
through, and CONIN$, CONOUT$, CLOCK$, COM0 and LPT0 were not listed. Those
reached the filesystem from a document or chat image before being refused.

Split on ':' as well, list the missing device names, and test each with
Windows path rules and zero filesystem calls. Also cover the case of a local
link that leads onto a network share outside every project (refused for chat
images), and correct the shared comment on chat-image access.

* fix(editor): let users rename and insert images into files opened outside projects

Renaming a file opened outside every project (tab double-click, editor
header) and inserting an image into such a markdown document failed with
"Access denied", even before a restart: both writes only passed the
project-root check. Document resources and chat images were also limited
by file type more strictly than users expect.

- Add a "document-folder" access kind for writes beside a document the
  user opened: main allows renaming only that document, to a name inside
  its own folder, and importing new files only into that folder, checked
  by path text and again by real path, with Windows device names refused.
  The renderer sends it only for local user-named, writable tabs (rename,
  its undo/rollback, image insert); SSH and runtime requests never carry it.
- Document resources: drop the image/PDF type allowlist; folder
  confinement, regular-file reads, the cap and path-text refusals remain.
- Chat images: judge only the real target's type, against every
  previewable image type (AVIF added).

* fix(fs): a declared file-access kind never refuses what the project check allows

A full-path tab for a file inside a project (for example a link that
leads out, opened by its absolute path) was renamed under the
document-folder rule, which limited the new name to the file's own
folder, although the same rename with no declared access could move it
anywhere in the project. Any declared kind could be stricter than the
default in the same way.

Every desktop local file request now goes through one resolver,
resolveLocalRequestPath: it runs the default project check first (roots,
Orca's floating folder, symlink containment, outside-root path text
refused before any filesystem call) and only on a refusal applies the
declared kind's rule, which adds paths outside projects. Reads, saves,
rename source and target, and import destinations all use it, so a new
kind gets the rule for free. Automatic loads (document and chat) still
refuse Windows device paths and names by text first, even inside a
project; a device is never a file to show.

The document-resource rule no longer needs its own project branch, and
chat images no longer re-run the roots check for shares.

* fix(fs): symmetric outside-project renames, notebook real folder, same-share images

- Renaming a file opened outside every project accepted a name in a
  subfolder (`archive/todo.md`), but the Undo and the rollback rename,
  declared from the moved file, were then refused and the file stayed
  moved. A rename under document-folder access must now land directly in
  the document's own folder (checked by path text before any filesystem
  call), so rename, Undo and rollback are symmetric. Image import still
  accepts the folder or a folder under it. Inside projects the default
  check still allows any in-project target.
- A notebook opened through a link inside a project started its kernel in
  the link's folder instead of the real file's folder (main's behaviour),
  because notebook and AI Vault log-tail paths skipped the project check.
  Both now resolve through resolveLocalRequestPath (project check first,
  then the user-file rule).
- A markdown file opened from a Windows share outside every project could
  not show the images beside it. Document images on a share are now
  allowed inside the document's own folder; the folder text check refuses
  every other host and share before any filesystem call.
- resolveDesktopAuthorizedPath is async, so a synchronous failure in the
  default check rejects like any other refusal.

* fix(fs): refuse share images outside projects again; keep renames and kernels as on main

- Reverts the same-share document image rule from the previous commit.
  Its folder check compared hosts case-insensitively, so a host spelled
  with U+212A KELVIN SIGN (or a decomposed accent) passed as the
  document's own share and was contacted, reopening the network
  credential leak. Document and chat images on a share outside every
  project are again refused by path text before any filesystem call;
  tests now cover the look-alike hosts with zero filesystem calls.
- Renaming a file opened outside every project into a project folder
  passed the project check, but its Undo (declared from the new path)
  was refused and the file stayed moved. When the rename source is
  allowed only as the opened document, the new name must now land
  directly in the document's folder even if a project would accept it
  (resolveLocalRenamePaths).
- A notebook opened through a link outside every project started its
  kernel in the link's folder; main used the real file's folder. The
  kernel cwd is now the real file's folder in every case.

* fix(fs): a file opened outside every project renames to any path, and keeps its access

Renaming a document the user opened (floating workspace or full-path tab) now
follows the user-file rule: the source must be the opened document, and the
new path can be any absolute path, so a rename into another folder, a
subfolder or a project works, and its Undo (declared from the moved file)
comes back from there. Any other rename keeps the project check only. Remove
the same-folder rename rule and its tests; image import stays in the
document's own folder.

After a move, a tab stored by its full path keeps its full path instead of
being recomputed project-relative, so it keeps user-file access for save,
the next rename, image insert and restore after restart. Folder moves go
through the same remap.

Also un-export unused resolver exports and avoid a copy for single-chunk reads.

* fix(test): pass getInsertionRange in the image-insert access test (#25351)

#25176 replaced insertPos with getInsertionRange and #24489 added a test
using insertPos; together they broke main's typecheck.

* Update README downloads badge

* fix(native-chat): start a new chat after an earlier start failed (#24917)

* fix(native-chat): start a new chat after an earlier start failed

A chat whose start the host refused stayed registered under its agent and
workspace, so the + menu and new-tab search kept that agent disabled with a
spinner, and any later "new chat" for that agent (for example "Send notes to
> New agent") restarted the failed chat instead and dropped its own prompt.

Only launches in flight now hold the agent/workspace slot that later starts
join. The registry keeps every launch by session id and derives the holder,
so a failed chat keeps its own Retry while a new start makes a new chat.

* test: import the launch status from its own module

* test: name the owning host on the launch intents the new tests build

* fix(native-chat): a new start never joins an unconfirmed or retried chat

A new start for an agent joined a chat whose create answer was lost, or a
failed chat whose Retry was in flight, and dropped its own text: the
source-control "Fix with AI" action reported success with nothing sent,
"Send notes to > New agent" sent nothing, and after a reload the text became
an unsent draft in the old chat.

Only a new start's own first create now coalesces later starts (double click,
two callers at once). Each attempt records whether it is that first create or
a Retry/re-check of an existing chat; an unconfirmed or retried blank chat
keeps its own Retry and a new start opens a new chat with its text. A resume
still re-checks or joins its conversation's launch, since the host refuses a
second adoption.

* fix(native-chat): a different new request always opens its own chat

A new start used to join any blank chat still in its first create or still
sending its opening text, so a second "Fix with AI" for another check, or
notes sent to a new agent, landed in that first chat. Each first attempt now
keeps the request it was started with (its text and whether it is sent or
drafted). Only a repeat of that request (a double click, a retried call)
joins it, and it shares the text already staged, so the text is sent once.
Any other request opens a new chat with its own text. The + menu, new-tab
search and send-notes menus disable an agent only when their own pick would
join. Resume launches are unchanged.

* fix(native-chat): an empty chat still starting takes the first text sent to it

A blank chat that is still starting (a + pick, the empty-workspace default
chat) is empty, so the first request with text, such as notes sent to a new
agent, now goes into it instead of opening a second chat beside it. That
request becomes the chat's own request: an identical repeat joins and is sent
once, and any other request opens a new chat.

Move the logic that decides which launch a start joins out of the launch
registry into its own module, so the registry stays under the line limit
once #24904 lands beside it. Pin that a repeat arriving while the opening
text is still sending is sent once.

* test: an empty chat delivers the claiming text the way its request asked

* fix(native-chat): only a chat its user has not used yet takes another request's text

A blank chat that is still starting was claimable by the first request with
text even after its user had sent a message into it or typed into its
composer, so notes or a Fix with AI prompt could land in a conversation the
user had already started. Emptiness is now read from what the chat holds:
nothing in its outbox and no text in its composer draft. A chat its user has
used stays theirs, and the request opens a new chat.

If the claiming text cannot be saved, the claim is not recorded: the request
falls through to a new launch, whose save failure shows on that chat as for
any new launch, instead of reporting a failure nothing showed.

* fix(notes): notes handed to a send leave the next send until it settles

Notes sent to an agent stayed in the notes shelf until their chat delivered
them, so a second "Send notes" made while the first new chat was still
starting collected the first notes again. With every different request now
opening its own chat, those notes reached two chats.

When notes or browser annotations are handed to a send (a new agent, a
running agent from the menu, or a sidebar agent row), they are held in
memory against that send's own delivery result and left out of the next
send. Delivered notes are removed as before; a failed, refused or
undelivered send releases the hold, so they come back for the next send.
The notes menu now builds each scope's prompt from the notes it will send.

* test: give the annotation tray fixture its hand-off callback

* fix(notes): offer no send when every note is already on its way

When every note or annotation in a send is held by an earlier send still in
flight, the built prompt is empty. The notes menu already disabled its
trigger then, but its New agent rows still started an agent with no text,
the annotation Send buttons still opened, and a sidebar agent row could be
sent an empty prompt. The New agent rows, the annotation Send buttons and the
sidebar send now offer nothing when there is nothing to send.

* fix(notes): a new chat's staged prompt decides when its notes leave the shelf

Notes sent to a new agent were released back to the shelf as soon as the
chat's start failed, while that failed chat kept the same text staged for its
own Retry. Re-sending and pressing Retry put the notes in two chats, and Retry
alone left delivered notes listed as unsent.

For a new chat, the notes now follow the prompt it staged: held while that
message is in the chat's outbox, cleared from the shelf when any dispatch
(Retry or re-check included) sends it on, and back on the shelf when the
chat is closed and its outbox thrown away. A paired server's chat is found
once its start settles. Running-agent sends keep their own result.

While notes are only on their way, the send button reads "Sending…" rather
than "All notes sent".

* fix(notes): a new chat's saved message keeps its notes out of another send across a reload

The hold that keeps notes sent to a new agent out of the next send lived only
in memory. A reload while that chat had not yet sent them put the notes back
on the shelf while the chat's saved message still carried their text, so a
second "Send notes" sent them twice.

The staged message now saves the send keys of the notes it was built from.
The shelf treats a note as on its way while any saved message carries its key,
read from the saved outboxes on first use and kept current by the outbox's one
write funnel. When a message carrying notes is sent on (its own start, a Retry
or the re-check), those notes are cleared from their shelf; when it is thrown
away with its chat, they come back. Browser annotations sent to a new chat use
the same keys while the app runs. Running-agent sends keep their in-memory hold.

This replaces the per-message watch and outcome promise from the previous
change.

* fix(notes): release a gone chat's notes, and clear sent ones in the web client too

Two gaps in keeping notes out of another send while a saved chat message
carries them:

- The web client never installed the clearing that removes notes once a
  chat sends them on, so after a Retry there the notes stayed listed. It is
  now installed, once per renderer, by the background services both the
  desktop and the web client load with App.
- A saved message carrying notes was thrown away only by this window's own
  close. A chat closed from the phone, another window or while Orca was off,
  or closed here without a known host, kept its notes held for good. A chat
  the host stops listing (affirmed, and not a launch still starting or
  failed) now has its queued messages thrown away once that sync lands, as
  does a close that can name no host, so the notes come back.

* Revert "fix(notes): release a gone chat's notes, and clear sent ones in the web client too"

This reverts commit ae0b9f3fea67d3073be8c8336335ad7527ed65b1.

* Revert "fix(notes): a new chat's saved message keeps its notes out of another send across a reload"

This reverts commit b88d0dc2cc78be26b0fe0b33fd76285b2172447d.

* fix(native-chat): a new chat joins only a re-delivery of the same user action

"The same request" was recognised by its content (agent, workspace, trimmed
text, sent or drafted), which split one action whose text changes between
deliveries ("Fix with AI" re-fetches logs) and merged two different actions
that happen to carry the same text.

Each user action now mints one request id where it is handled (the click,
menu pick, notes send, shortcut, Fix with AI press, quick command; a worktree
create uses its creation id; programmatic starts mint once at their entry)
and passes it through the launch plan, its verdict and the structured launch
options, where it is required. A new start joins a chat only when its first
attempt carries the same id: a double click or a caller retrying its own call
makes one chat and sends the first delivery's text once; any other action
opens its own chat, whatever its text. An empty chat that is still starting
is still claimed once by the first action with text, and then belongs to that
action's id. Resume launches keep joining their conversation's launch.

The + menu and new-tab search no longer grey out an agent while one of its
chats starts: every pick is a new action and opens its own chat. The id lives
in memory only; nothing reads it after a reload (a restored launch is reached
by its session id through Retry, never joined).

* fix(native-chat): a new chat with no text reuses an empty one instead of stacking another

Two bare "+ > Claude" picks (or new-tab search, the new-agent shortcut, the dashboard) opened two
empty chats. A request with no text now focuses an existing empty chat for that agent in that
workspace: one still starting (joined in the launch, as a re-delivery is) or one that published and
sits idle (its host's journal holds no request, read live from the status feed). Empty also means
nothing queued, no composer text or images, and no launch draft its composer has not taken. Failed,
unconfirmed, resumed and other-agent/workspace chats are never reused. A request with text still
opens its own chat, or claims an empty starting one as before; request-id dedupe is unchanged.

* fix(native-chat): a new chat with no text reuses an empty chat only in the split it was opened from

Pressing + in the right-hand split focused an empty chat sitting in the left-hand split. The reuse
now looks only in the tab group the pick targets (the caller's group, else the workspace's active
group, which is where its tab would open); a pick in another split opens a new chat there. Applies
to both an empty chat still starting and one that published and sits idle.

* fix(native-chat): text sent to a new agent claims an empty starting chat only in its own split

Notes sent from the right-hand split could land in, and focus, an empty chat still starting in the
left-hand one. A request with text now claims an empty starting chat only in the tab group it opens
in, the same rule a request without text follows; elsewhere it opens its own chat there.

* fix(test): give async image-insert store mocks the openFiles list (#25357)

#25176 and #24489 landed together and collided in
insertRichMarkdownImageFromPath. #25176 added three test files whose
@/store mock returns { settings, folderWorkspaces, worktreesByRepo }.
#24489 made the same function look up the open document with
state.openFiles.find(...) to pass document-folder access to the import.
Under the mock, openFiles is undefined, so the lookup throws, the catch
shows "Failed to insert image", and no image is inserted -- 38 tests
fail on main.

The real store always carries openFiles, so production behavior of both
PRs is intact; the mocks were just written against the pre-#24489 shape.
Add openFiles: [] to the three mocks.

* fix(relay): skip the dead-cell sweep's host scan when no cell qualifies (#25350)

evacuateDeadCells ran one query that joined every assignment to its cell's
liveness and fence state, ordered by primary key with LIMIT 100. In
production no row ever matched (the only dead cells are stale existing-only
cells without a committed fence), so the planner walked the whole
relay_assignments primary key every call: 551 ms mean over 85k calls,
~12% of relay database time.

A cell-level pre-check now evaluates the predicate's cell-only half over
the ~33-row cell tables (3 ms in production). It is a superset of the cells
the host query can act on, so the sweep returns early when it is empty and
otherwise restricts the host query to those cells. The host predicate is
unchanged.

* fix(relay): prune released control-connection reservations in bounded batches (#25352)

relay_control_connection_reservations was never deleted: 13.8M rows and
9.1 GB in production, 99.999% of them in state 'released' and ~400k more
a day. Nothing reads a released row (every reader filters it out by
state), but each placement still locks all of its host's rows, ~160 on
average.

A new director sweep step deletes released rows older than a day. It walks
the heap in TID ranges of 16 pages, because without an index on
released_at a `LIMIT n` delete plans as a sequential scan from page 0 that
gets slower as the head of the heap empties (production EXPLAIN). Each
statement selects its rows FOR UPDATE SKIP LOCKED, so a row a request holds
is skipped rather than waited on, and deletes them by `ctid = ANY(ARRAY(...))`
so the delete is always a TID scan. A tick stops at 400 rows, 128 pages or
250 ms, which drains the backlog over about three days at five directors.

* chore(relay): move US cells c32 and c33 to the general same-cap list after promotion (#25367)

Both were promoted to general on 2026-10-01 (selector 344 shows them general),
but the same-cap job still classed them migration-only. Rollback mode on either
would isolate (general -> migration-only) before its no-op check failed, demoting
a live cell. They stay out of the fleet pool list (pool 10, not 16).

* Support modern Qoder commands and verify authenticated resume

Start and resume Qoder through the existing execution-host selector when only the documented qoder command exists. Preserve legacy qodercli preference, explicit commands, quoting and session identity; disconnected SSH execution refuses without local fallback.

Mobile history uses command-at-create only with the optional owned-create capability and an existing stable mutation identity. Reconcile authoritative execution-host inventory before retrying creation, adopt the same surviving operation, preserve WSL/incarnation metadata and restore only missing original launch metadata. Changed retry settings cannot replace original capture. Bounded evidence expires after 15 minutes; unavailable inventory or original evidence refuses recovery and leaves surviving execution untouched. Authoritative inventory proving absence preserves the existing recreation behavior; this is not a durable exactly-once ledger for completed one-shot side effects. Older hosts retain the acknowledged create-then-send path.

Scope mobile launch authority to the current committed host/client generation, and recheck operation ownership after asynchronous preparation before later sends. Retire the mutation once the host acknowledges the resume; later ownership changes stop navigation without reporting a completed resume as failed or reusing a cached legacy pane. Preserve genuinely interrupted mutation identity. Preserve current-main OpenCode validation and merged Pi/Cursor behavior. Correct unchanged-main editor test fixtures to their production insertion-range and store contracts while retaining original assertions and production behavior.

Credit: Neil Parker (@nwparker); Soperf and jyang for Qoder integration/history groundwork in #24614; actual Pullfrog and CodeRabbit reviews and the independent Source reviewer for the mobile retry, launch capture, evidence lifetime and connection ownership findings. Conservative positional process recognition and existing folder-history matching-worktree limitations remain documented.

* fix(relay): retain confirm results for a week and audit events for 90 days (#25353)

* fix(relay): retain confirm results for a week and audit events for 90 days

relay_confirm_results (8.3M rows, 5.8 GB) and relay_audit_events (8.4M
rows, 3.6 GB) were never deleted. The director's credential cleanup now
reaps both after its existing passes:

- Confirm results older than 7 days. The only reader replays a stored
  result for a retry of the same request on the same connection basis; a
  different basis is already refused as a tuple mismatch. committed_at has
  no index, so this uses the TID-window reaper from the reservation prune,
  capped at 250 rows a tick (the 7.4M-row backlog drains over 2-3 days).
- Audit events older than 90 days, ordered by `at` so the batch walks
  relay_audit_events_at. Nothing in the relay reads them back. The oldest
  row is from 2026-07-14, so this deletes nothing until 2026-10-12.

reapBatch now deletes by `ctid = ANY(ARRAY(...))` on Postgres: with
`ctid IN (...)` the planner can choose a hash join over a sequential scan
of the whole table.

* refactor(relay): stop creating three tables nothing writes

relay_confirmable_splices, relay_cell_drain_attempts and
relay_migration_leases are created at every boot and referenced nowhere
else on main except tests. In production all three hold 0 rows and
pg_stat_user_tables shows 0 inserts, 0 sequential and 0 index scans since
the 2026-09-28 stats reset.

This removes them from the schema and the transaction-phase table, and
drops the test references. It does not drop them: an older image still
runs CREATE TABLE IF NOT EXISTS at boot, and a drop racing that create can
fail the older boot's schema step. A follow-up can drop them once no image
that creates them can be rolled back to.

* fix(mobile): honour the desktop pinned-worktree placement setting (#25301)

* fix(mobile): honour the desktop pinned-worktree placement setting

Mobile always kept pinned rows in their groups as well as in Pinned. Desktop's
showPinnedWorktreesInGroups (default off) shows them only in Pinned. Read that
setting with its own settings.get operation, refreshed with the list's view
settings, and leave host and device-local pins out of their groups unless it
is on.

* fix(mobile): keep lineage children with a pinned parent

Under single-location a pinned parent left its group while its unpinned child
stayed behind as a root. Visible descendants now follow a pinned ancestor into
Pinned, nested under it, as on desktop. Drop the inert host-id half of the
pinned-policy stale-reply guard; a host switch replaces the client.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* refactor(mobile): fold pinned placement into the desktop view-settings sync

One "sync from desktop" callback now also reads settings.get for pinned
placement, unawaited so a slow read never holds the ui.get merge; the separate
callback and its plumbing are gone. Re-record the three host.view-settings
goldens, which gain only that settings.get send. The pin expansion walks the
lineage children index the renderer now shares, over visible rows only.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* refactor(mobile): one stale-reply rule for the desktop view-settings sync

Both reads in syncViewSettingsFromDesktop now drop a reply only when the client
was replaced; the host-id half compared a captured value with itself. Pin the
no-wait invariant: the ui.get merge applies while settings.get never answers.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* fix(mobile): follow a pin through rows hidden by search

Desktop's Pinned section walks lineage over every worktree and keeps the
visible descendants, so a grandchild still follows a pinned root when search
hides the middle row. Mobile walked visible rows only and left it in its group.
Build the children index from the unfiltered list; membership stays visible-only.
Drop the hostId arg the view-settings sync no longer reads. Pinned-lineage
tests move to their own file to stay under max-lines.

* refactor(mobile): read pinned placement in its own hook

The placement read was folded into the desktop view-settings sync, so that
callback juggled an awaited and an unawaited read and three goldens recorded a
settings.get that never answers. useHostShowPinnedInGroups now owns the setting
and the catalog refreshes it beside the view-settings sync on connect, focus and
mount; the sync, screen state and goldens are back to main.

The reader returns desktop's boolean, as its siblings do, so transport no longer
imports a worktree type and the two-literal policy union is gone. makeSection
always applies lineage, the pinned walk is a Set worklist, and the lineage
children index drops a set that duplicated its map's keys.

* fix(mobile): key pinned placement to the client that reported it

The host screen is reused across hosts, so the previous host's "show in groups"
value survived a switch until the new read landed, or for good if it failed.
The setting now carries the client that reported it and counts only for that
client, which also makes a late reply from a replaced client inert and drops
the clientRef plumbing.

* fix(mobile): drop a replaced client's late placement reply

Keying the value to its client hid a previous host's value but still let that
host's late reply overwrite the current host's, reverting the list to the
default until the next refresh. Restore the clientRef write guard; the client
key still covers the effect-long window before clientRef follows a switch.

* refactor(mobile): treat pinned placement like the screen's other host state

The placement hook kept its own host-switch handling (a client-keyed value plus
a clientRef guard) beside the screen's existing one. showPinnedInGroups now
lives in HostScreenState, resets with the other host-scoped values in
useHostScreenIdentity, and is read in the catalog refresh behind the same
clientRef check as the catalog fetch. The hook and the catalog argument go.

* feat(relay): declare Asia spare cell c34 as migration-only (#25336)

Adds a sixth asia-east2 cell at the C31 shape (cap 3000, 6000 request
units, pool 16, e2-standard-4) in asia-east2-c, pinned to the f30b5cb1
cell image. It gets its own topology and registration wave but no
promotion wave, so the admission script and workflow refuse to promote

* fix(activity): keep code blocks in row previews from rendering as scroll boxes (#25410)

The activity row previews the agent's last reply with the compact markdown
renderer, which draws fenced code blocks and tables as their own scrollable
boxes. Those boxes escaped the row's line clamp, so a reply with a code block
put a tall grey box with scrollbars in the middle of the list.

Row-scoped overrides now flatten code blocks and tables into plain wrapping
text, so the existing clamp cuts them like any other line. Other markdown
surfaces are unchanged.

* fix(native-chat): show a reply cut off by an Orca crash or quit like a finished turn, with one explanation (#25043)

* fix(native-chat): read a crash-cut reply like a finished turn, with one explanation

A reply that an Orca crash or restart cut off said it failed three times: the
turn bar read "Failed after N", the chat's notice row said Claude stopped, and
the sidebar dot stayed red after the chat was read.

The turn bar now reads "Worked for N" for a proven crash/restart cut, the
notice row stays the one explanation, and the sidebar card's dot and agent
rows read failed only until the user has visited the chat (the same
acknowledgement that un-bolds the row), then read done. A failure, a user's
Stop, a replaced turn and an unconfirmed end keep their labels. The stored
outcome is unchanged.

* fix(native-chat): explain a turn a quit or eviction cut, once

A turn cut off by quitting Orca, an idle eviction or a teardown recorded the
same outcome as a crash-cut turn but wrote no notice row, so with the turn bar
now reading "Worked for N" nothing in the chat said it stopped.

The host stop's settle now writes the existing providerExited notice for the
latest turn when it ends as news (no person's Stop decided it): in the same
write as the host's own turn end, or right after the adapter's. It is keyed by
the turn, and skipped when an error row already explains that turn, so a retry
or an earlier exit row never leaves two.

* test(native-chat): narrow the turn scope and add the seen map in the crash-cut tests

* fix(native-chat): derive a cut turn's one notice on read instead of writing it at stop time

A turn cut short when the agent stopped without anyone asking now reads
"Worked for N", so it needs a row saying it stopped. Writing that row only on
the quit and eviction paths missed journals written before this change, a quit
that died between its drain and its settle, and any future stop cause.

The transcript now derives it from the journal on desktop and phone alike: a
root turn that ended interrupted with no verdict and no row about the stop
gets one notice in the provider-exit row's words. A stored exit row, matched by
its exit fact or its writer's identity rather than its tone, stays the
explanation, and so does the restart continuation's own outcome note, so a
refused resume says it once. The host's stop path is back to what it was.

* fix(sidebar): read a cut-short turn's red mark from its acknowledgement on every surface

A turn cut short with nobody asking reads failed only until the user has seen
it. The previous revision passed an optional "seen" flag to each caller, so any
surface that did not pass it, the chat's own tab dot among them, stayed red
beside a sidebar that read Done.

The verdict's display now takes the acknowledgement as part of what it reads:
the entry's stateStartedAt beside the time the user last acknowledged it, both
required, judged by one shared rule. Each surface joins it once where it builds
its rows: the sidebar's agent rows (and so the notes send menu), the workspace
card summary, the terminal tab bar, Cmd-J recent rows, and Activity threads.
Failures, Stops, replaced turns and unproven ends keep their marks as before;
the phone, which has no acknowledgement record, keeps the unseen reading.

* refactor(attention): use the one acknowledgement rule where it was copied

Auto-acknowledgement, the Activity unread count, dashboard row buckets and
notification acknowledgement each spelled the same "acknowledged at or after
the current state began" comparison; they now call the shared rule.

* test(mobile): type the cut-turn notice test's client and hook holder

* test: pin an older host's exit row by its writer and the sidebar rows' acknowledgement join

* test(sidebar): re-read the card and the tab when only an acknowledgement changes

* fix(native-chat): keep a cut turn's notice through a resume that carries on

A resume after a quit writes its "asked this agent to continue" note after its
own message, so counting that note as the cut's explanation removed the notice
once the resume went on, and made it flash away under automatic resume. Only the
notes that say the chat was not carried on (refused, not connected, not
confirmed) stand in for the notice now.

A row about the whole conversation now explains a cut turn only when no other
turn lies between them, and a failed start's row, which is about a start, never
does. The host writers and the rule share the row identity prefixes, with the
contract that a new row explaining a stop carries the provider-exited fact or
one of them.

* fix(sidebar): judge a cut as seen by the main agent's clock when a subagent holds the row

A subagent can keep a row working after its main agent was cut, and the row's
clock then predates the cut, so a look at the working chat counted as having
seen the cut and no red mark showed. The mark now compares the acknowledgement
with the later of the row's and the main agent's clocks; auto-acknowledgement of
the chat on screen reads the same clock, and its stamp covers it, so looking at
the chat still clears the mark. Bold rows, dashboard buckets, notifications and
unread counts keep the row's clock.

* fix(native-chat): tie a conversation-wide exit row to a cut only with no message sent since

A send after a quit's cut whose new agent died before its turn opened leaves a
provider-exit row about the whole conversation. That row is about the send,
not the earlier cut, so the cut kept no explanation. An exit row now explains
a preceding cut only when no message was sent in between; the restart notes,
which follow the continuation's own message, still need only no turn between.

The notes that say a resume did not carry the chat on are now told apart from
the continued note by their tone ('error' or 'warning'), which every host that
wrote them has set, instead of by their words.

* fix(native-chat): keep an owner's proven death the explanation of its cut after a send

A chat read before the startup reconcile settles its cut turn unverifiable;
if the user then sends a message, the reconcile proves the old agent dead and
writes its row about the conversation after that message. The row names the
old owner's death, never the send, so a message since no longer detaches it
from the cut. Only a provider-exit row, which a later start can write, still
needs no message sent since.

* test(sidebar): give the activity-status store mock the acknowledgement map

The card summary now reads acknowledgedAgentsByPaneKey; this test's hand-built
store state lacked it, so every summary read threw.

* refactor: move the seen-gated red mark out of this change

This change now keeps only the cut turn's label and its one derived notice.
The red mark that clears once the user has seen a cut turn moves to its own
change, so each can land alone; until it lands, the sidebar, tab bar, Cmd-J,
Activity and the notes send menu read a cut turn as failed, as before.

* test(native-chat): pin that a restart note after a continuation's turn leaves the cut's notice

* test(native-chat): keep a cut turn's notice beside a later message drawn as not sent

* fix(mobile): stop Android from selecting words while the chat transcript scrolls (#22871)

* fix(mobile): stop Android from selecting words while the chat transcript scrolls

On Android every paragraph, heading, quote, code block and table cell in
the native chat transcript was a selectable TextView. Android starts a
word selection, with the magnifier, on a double tap or a long press, and
two flicks in the same spot while scrolling a FlatList register as a
double tap, so scrolling the chat kept selecting words. iOS is unaffected:
its UITextView path arbitrates scroll against selection itself.

Android now renders transcript text without inline selection: one gate in
MarkdownText covers every selectable span, and the user bubble follows
it. A long press on a message opens a sheet with "Copy message" and
"Select text", the latter a screen whose only content is one selectable
Text, so a selection can only start where the user asked for it. The
message row owns that sheet and mounts it only while open. iOS and web
keep their inline selection and get no long-press handler.

Verified on a Pixel 10 Pro Fold (Android 17): an adb double tap on the
transcript selects nothing, the same double tap inside "Select text"
selects a word, tool rows inside the bubble still expand on tap, and the
long press opens the sheet.

* fix(mobile): scope the Android selection gate to the transcript and route span long presses

Review follow-ups on #22871:

- The gate now applies only where `rangeSelectable` is passed (the chat
  transcript). Task comments and file previews keep their selectable text
  on Android as before.
- On the Android transcript, spans that take taps (links, file paths)
  also take the row's long press, so a link under the finger no longer
  swallows the copy/select sheet.
- Copied text keeps its whitespace; only whitespace-only blocks are dropped.
- The Android markdown test compares `String(node.type)` instead of a
  type assertion, which the changed-code quality gate rejects.

* fix(mobile): route long presses on Markdown images to the row on Android

An image block is a Pressable of its own, so on the Android transcript it
now carries the row's onLongPress like tappable spans do; a long press on
an image opens the copy/select sheet instead of being swallowed. Test
extended with an image block.

* test(mobile): pin the Android long press from a chat row to its actions sheet

The existing row suite runs as iOS, where the bubble has no long press.
This one runs as Android: the bubble's long press mounts the actions
sheet with the message, the markdown receives the same handler, closing
unmounts the sheet, and the user bubble carries no inline selection.

* fix(mobile): preserve Android message selection while replies stream

* feat(jira): pick the assignee when creating an issue — Automatic, me, or anyone (#24376)

* feat(jira): pick the assignee when creating an issue — Automatic, me, or anyone

The new-issue dialog gains an Assignee picker: Automatic (Jira applies the
project's default assignee), one-click "Assign to me" resolved from the
target site's stored identity, or any user via search. The selection resets
with the custom field values on project/type switches, since account ids
are site-scoped.

Creates now also send userFieldKeys, so the host shapes user-typed values
into the {accountId}/{name} refs Jira requires — previously the dialog
never passed them and user create fields were sent as bare strings. Keys
are only named when a value is present, keeping older remote hosts without
the user-fields capability working for assignee-less creates.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* fix(jira): address assignee review — project-scoped assignable search, per-site picker remount, keep assignee across type changes

- Search the create dialog's assignee picker against /user/assignable/search?project=…
  (new listAssignableUsersForProject, IPC split into jira-user-search.ts for the
  max-lines budget); remote environment targets fall back to the existing
  site-wide search since older hosts have no such RPC
- Remount the picker per target project so cached results from the previous
  project or site cannot be selected after a switch
- Reset the picked assignee on project selection (account ids are site-scoped)
  instead of on every create-fields reload, so issue-type changes keep it
- Hide the assignee field and omit it from the payload when the target create
  screen does not accept an assignee — Jira rejects fields absent from the screen

* Update README downloads badge

* refactor(terminal): one commit module for terminal topology closes, with a boundary check (#25329)

* refactor(terminal): move the topology revision and leaf-lookup helpers into terminal-topology

advanceTerminalTopologyRevision, findTerminalTabIdForLeaf and
hasHostAuthoritativeTerminalMembership move verbatim from the renderer-save
membership rebase into persistence/terminal-topology, the home of the commit
boundary. Importers are repointed; no behavior change.

* test(terminal): test-only guard for topology writes outside the commit boundary

The three session sinks now publish through one commitWorkspaceSessionPartition
helper, which hands the prior and published partition to the topology write
guard. Production never arms the guard, so each sink pays one global lookup.

The unit suite arms it in report mode: a sink write that changes class-(a)
topology (membership, root, bindings, titles, incarnations, sleeping records,
remote session ids, tombstones, default-applied, revision) outside a commit
scope is attributed to its writer's file by stack, and fails the test unless
the writer is on the unrouted-writers allowlist that later routing PRs shrink.
Renderer saves and test seeding are exempt. Deep-freeze is available but stays
off suite-wide until the in-place writers return new sessions.

* refactor(terminal): add the topology commit module with bindLeaf, closeLeaf and closeTab

terminal-topology-commit.ts is the boundary for class-(a) terminal topology.
bindLeaf forwards to persistPtyBinding, whose write now runs in a commit
scope; the spawn commits and the relay reattach bind through it. closeLeaf and
closeTab wrap the existing close mutation in a commit scope and one
persistence.terminal-topology span (kind, outcome, refusal reason; no ids),
and the runtime close goes through them. Session output is unchanged: tests
compare it byte for byte with the old writers for local, ssh: and folder
workspaces.

* chore(terminal): drop an unused lint suppression from the topology write guard

* fix(terminal): attribute topology guard writers relative to the repo root

The guard read a frame's file through its last /src/ segment, so a test under
tests/ (folder-upgrade-identity-persistence.unit.test.ts) had no source frame
and failed as an unknown writer. Frames are now taken relative to the repo
root the setup passes in, tests/ counts as test seeding, Windows backslashes
are normalized before the node_modules skip, and nested src/ paths keep their
full path. The two runtime funnel files skip only their funnel function, so
another writer in them still shows. The R9 allowlist key names the file whose
frame actually writes. The class-(a) diff and the attribution move into their
own files; the stack limit is restored in a finally.

* refactor(terminal): drop bindLeaf until binding reaches a sink; add the boundary ratchet

bindLeaf and the commit scope inside persistPtyBinding changed nothing: the
binding write never reaches a session sink, and a scope inside the Store method
would have admitted every direct caller once it did. Both return in B1-4; the
spawn commits and the relay reattach call persistPtyBinding directly again.

The runtime close now calls one closeLeafOrTab entry, so its callbacks keep
their contextual types. A census test is the primary enforcement: only
persistence/terminal-topology and the callers it lists may call
persistPtyBinding, the session setters or the three sinks, and every
unrouted-writer allowlist entry must name an existing file.

* fix(test): resolve the topology guard's repo root without the global URL

Under happy-dom the global URL is not Node's, so fileURLToPath(new URL(...))
threw in the setup file and failed every happy-dom test file.

* refactor(terminal): drop the runtime topology write guard; the boundary ratchet enforces

The AST boundary ratchet is the enforcement for B1. The stack-attributed
runtime guard, its class-(a) diff, the unrouted-writer allowlist, the vitest
setup and the freeze option are removed; it saw two writers in the whole unit
suite and its real value starts only once binding reaches a sink (B1-4).

Also: one closeLeafOrTab wraps the close in the span (no per-kind copies or
narrowed types), the span has one finish like persistence.pty-binding, the
sink helper is publishWorkspaceSessionPartition (it publishes; the commit
boundary is the module), the ratchet drops the private publishSession row and
checks that every listed caller file exists, and the close comparison keeps
its two meaningful cases with span cases chosen by name.

* refactor(terminal): trim the B1-1 commit module and ratchet to what they enforce

- Point the acknowledged-tab-retirement audit fixture at the moved
  advanceTerminalTopologyRevision; its old import no longer resolved.
- Drop publishWorkspaceSessionPartition: it was the removed guard's
  interception point, so the three session sinks return to origin/main.
- One traced(kind, mutate) wrapper in the commit file replaces the span
  factory; closeLeafOrTab is one call.
- The ratchet walks src/main with the shared scanSourceTree, drops the
  loading-store-internal rows and the redundant file-exists test; exact-set
  equality already fails on a missing file.
- The commit test is a pure unit test of the span outcomes: no Store
  harness, electron mock or self-comparing close.

* refactor(terminal): census the runtime session controller's write and drop stage ids from comments

The controller's setter was named set, which the boundary census could not
list without matching every Map.set, so a new OrcaRuntime mixin could write
sessions through it unseen. Rename it setForWorktree and census it.
Comments now describe state instead of citing plan stage ids.

* refactor(terminal): census writer references and trace refusals by callback

- traced() takes refusalOf instead of assuming an Error refusal, and only
  mutate() sits in the try, so a span outcome of threw means the write threw.
- The boundary ratchet counts references, not just direct calls: non-null
  calls, bracket keys, aliases, destructures, .call/.bind and parenthesized
  callees all count; declared names and type positions do not.
- Census terminalSurfaceCloseMutation (boundary-only) and the partition sinks
  setLocalWorkspaceSession / setHostWorkspaceSession.

* test(terminal): count writer uses in extends clauses and instantiations, skip type-only imports and local declarations

The census skipped ExpressionWithTypeArguments as a type, which also holds
`extends f(x)` and `x<T>` value expressions. Type-only import/export
specifiers and declared names (variables, parameters, accessors, enum
members) no longer count as uses. The audit fixture is listed in the table
instead of a separate exemption.

* test(terminal): count quoted and assignment-pattern destructures of layout writers

* test(terminal): count every mention of a layout writer except its definition

Telling definitions from uses per syntax kind kept missing nested and
for-of destructures. Exempt only the writer's own function or class-member
definition; any other mention (including object-literal keys) counts, so the
census errs toward a loud false alarm rather than a silent miss. Quoted names
count only in member-name position.

* test(terminal): count every string literal naming a layout writer

Member-name positions missed wrapped keys like store[('name')] and
store['name' as const]. Counting every string literal outside types is
shorter and errs toward a loud false alarm.

* test(terminal): exempt only class members and functions as writer definitions

Object-literal methods and accessors were exempt while equivalent arrow
properties counted; all object-literal keys now count alike.

* test(terminal): parse files with unicode escapes in the writer census

A name spelled with a \u escape never appears verbatim, so the text
prefilter skipped it.

* test(terminal): parse any file with an escape in the writer census

\x, identity and line-continuation escapes also decode to a writer name
without it appearing verbatim.

* fix(native-chat): a Stop binds only the turn it actually stopped (#24864)

* fix(native-chat): a Stop binds only the turn it actually stopped

A Stop pressed before any turn showed used to claim, at end-write time,
whatever turn the stopped send later opened, even when the Stop stopped
nothing. A turn that then died on its own read as "Interrupted" (your
cancellation) instead of "Failed".

Now a person's Stop that named no turn binds, in memory only, every turn
that ends while the Stop settles, and afterwards only the turn its
interrupt took. The settle ends a still-running stopped turn once. A
relaunch finds nothing in memory, so an unsettled turnless Stop binds no
turn. A Codex Stop whose answered turn does not open within its wait, or
whose send's answer was lost, now answers refused, so the host ends the
child and the turn can never run.

* fix(native-chat): keep the person's queue pause and close binding after a Stop settles

A host stop or eviction with no turn running now defers to a person's
Stop while its queue pause still holds with nothing sent since, read from
rows, so a held card is not handed off on reopen after a Stop that did
nothing or whose kill failed.

A person's close that named no turn opens a settle around its child's
end, so a turn that end cuts reads as theirs.

A press opens its settle only when the latest Stop event is its own or
the one in force it repeats: a late Stop, a card's interrupt or a lost
event row reopens no earlier Stop.

A Codex Stop that cannot reach a turn still able to open says the Stop is
unconfirmed rather than that no turn ran, and a second Stop still reaches
a turn an earlier wait left unopened.

Also drops the unused openedBy plumbing and the unreachable "a written
cancellation stays one" rule, and pins a relaunch after a named Stop.

* fix(native-chat): a Codex Stop agrees on both presses when a turn is still owed, and pin the close's settle

A Codex Stop that waited for a turn Codex answered a send into now answers
"may still open" whenever that turn neither opened nor ended and its send
is still owed, however the wait ended (it ran out, or the thread went
idle). Before, a first press after an idle thread said no turn was
running and kept Codex, while an identical second press ended it.

Adds a test that a person's close the conversation outlives (as /clear
does) closes its settle, so a later turn that ends on its own reads as a
failure.

* test(native-chat): a Stop whose event row failed binds no turn to an earlier Stop

With one ordered journal writer the Stop's event is in the fold when its
write returns, so the press reads whether it owns the latest Stop from the
fold instead of awaiting the write. Pins the case the read must refuse.

* test(native-chat): name the settle, not a stream drain, in the Stop's own-end test

* test(native-chat): a Codex Stop answered before Codex ends the turn reads interrupted throughout

Codex answers an interrupt it took before it sends turn/completed (interrupted):
on TurnAborted the app-server answers pending interrupts, then ends the turn, on
one channel. The test fake did the reverse. It now answers first and ends the
turn on a later read, and the tests that read the turn's end right after a Stop
wait for it.

New end-to-end test through the shipped host, journal and Codex adapter: with
the real order, every end row of the stopped turn reads interrupted by the Stop
(named, unnamed, and a Stop pressed while turn/start was in flight). Breaking the
settle window turns the in-flight case red: the Stop's own end row then has no
verdict, which reads as failed until Codex's end lands.

* fix(native-chat): a Codex Stop interrupts a turn Codex answered but has not opened at once

A Stop that named no turn, made after Codex answered a send but before the turn
opened, used to wait up to 5 s for the turn to open before interrupting, and
ended the Codex process when it didn't. The stated reason, that Codex refuses an
interrupt until it opens the turn, holds only part of the time: with no turn
active, Codex takes an interrupt once its thread runs (turn_interrupt_inner),
and refuses it with -32600 "no active turn to interrupt" before that or once
the turn has ended.

The Stop now sends the interrupt at once. Only on that refusal, while the turn
has neither opened nor ended, does it wait for the turn to open (bounded at
5 s) and send it once more. A turn that ended meanwhile was nothing to stop. One
that never opens, or that an earlier wait already gave up on, fails the Stop,
and the host ends the child as before. Sends still wait for the turn to open
before steering into it.

The test fake models Codex taking an interrupt once the thread runs (run()).

* fix(native-chat): every Codex Stop waits for an answered turn to start, as the first did

A Stop whose interrupt Codex refused as finding no active turn skipped the wait
when an earlier wait, a Stop's or a send's, had already given up on that turn.
Every press now waits its own bound and retries once if the turn starts, so a
turn that opens during a later press is still stopped. Both presses still reach
the same verdict when it never starts.

* fix(native-chat): a Codex Stop that ends the child before any turn opened withdraws its send

A Stop on a Codex turn that was answered but never opened ends the Codex
process. That end settled the send as in doubt (unknown, recovered), and the
client's outbox holds every later send behind a send in doubt until the person
presses Retry, which re-sends the very message they stopped. The chat looked
stuck.

Codex records a prompt only once its turn has started, so a send whose turn
never opened never ran. When the Stop's refusal says so (turnMayOpen), the child
end now settles the unanswered sends as withdrawn, the verdict Codex's own
interrupted-turn end already gives an unechoed send. The flag rides on the owed
wind-down, so a retry after a failed child end withdraws them too. Claude's
child end still leaves its unanswered send in doubt.

* fix(native-chat): derive the withdrawal of a Codex send whose turn never opened

Replaces the flag the Stop carried to the child's end, and its copy on the owed
wind-down, with a reading of the journal at the settlement that lands. A Codex
child's unanswered send is withdrawn when a person's Stop is in force since it
was sent and no turn row ran, or was written, after it; any other end (a turn
that opened, a host's close, a crash, Claude) still leaves it in doubt. A
retried wind-down reads the same rows, so it withdraws the same sends.

* fix(native-chat): keep a send in doubt when a turn was open for it

The derived withdrawal read a turn as open for a send only if it still ran or
was written after the send. A send steered into a running Codex turn whose
interrupt failed met neither once the adapter's end settled that turn ahead of
the host's settle, so it read withdrawn, though Codex drains a steer into the
running turn and may hold it. A turn that ended after the send was handed over
was open for it too: such a send stays in doubt, as before.

Pins that case, and that a send made after the Stop, to a child that then dies
before its turn opens, stays in doubt.

* fix(native-chat): withdraw a Codex send by whether it started its own turn, not by timing

Whether a turn was open for a send was read from end times: a turn that ended
after the send's handover counted. A send made while a Stop ended the turn is
handed over once that turn reads ended, yet Codex's own end for it can arrive
later, so such a send whose own turn never opened read in doubt again, and the
chat's queue held behind it.

The handover already records where the send went: its message joins the turn
running then (a steer) or belongs to no turn (it starts its own). Only a send
that started its own turn, with none opened since, is withdrawn; one that
joined a running turn, or has no recorded place, stays in doubt.

The Codex test fake takes an answered interrupt as Codex does, dropping the
turn before its end arrives.

* fix(native-chat): leave no Stop row when the Stop took back a send that never ran

A Stop on a Codex send whose turn never opened ends the child, and the child's end
takes the send back into the composer. The Stop still wrote "Cancellation
requested." at the conversation level, so with the send gone it sat under the
previous finished turn and read as if that turn had been stopped. A Stop that found
no turn running and whose child end took back every send it found now writes no
row; a Stop of a running turn, or one that leaves a send in doubt, still does.

* fix(native-chat): count a send whose answer was lost when a Stop takes it back

The no-row rule counted only pending sends, but the child's end also takes back a send this process left in doubt when Codex's turn/start answer was lost. That case still wrote "Cancellation requested." under the previous turn. Both now read one predicate, so they cannot drift apart.

* test(native-chat): pin which sends a Stop's child end can take back

A send an earlier process left in doubt is never withdrawn and never holds the row back, and a queued card's send is never counted.

* fix(native-chat): a chat's finished-turn alerts come from the host recorded on its tab, not its workspace id (#25081)

* test(native-chat): a mirrored paired chat carries its host, so a workspace-id collision no longer hides its owner

* fix(native-chat): a chat's finished-turn alerts come from the host stamped on its tab, not its workspace id

* fix(native-chat): the attention bridge reads a chat's owner from the same rule as the chat pane

* fix(native-chat): never delete chat history on read; a chat Orca can't load says why once (#24576)

* fix(native-chat): an older Orca keeps a chat with newer content read-only, and an unreadable annotation costs only itself

A body or lifecycle mutation of a kind this build does not know, inside a row of a known kind,
now latches the chat read-only with every row kept, as a newer row kind or version already does.
It used to read as damage, and the open deleted the journal from that row on.

Each optional field of a body schema now declares what an unparseable value means:
- droppable (an annotation): removed from the row in memory; the chat stays writable;
- must-understand (a prompt's questions, a plan approval's plan, a turn's lifecycle, a goal
  change): the row is unreadable and the chat latches read-only.
Only a required field that fails is damage, repaired as before. A test holds every optional
field reachable from a body schema to a policy; the known body kinds are read off the schema.

Prompt options and questions no longer reject a key this build does not know, which deleted the
journal from that row on. The context-usage drop is now one case of the droppable rule.

* feat(native-chat): a chat an older Orca keeps read-only says so before a send is refused

A chat a newer Orca wrote opens read-only, and until now nothing said so: the person found out
when a send failed with "Chats were saved by a newer Orca". The host now names the reason on
every whole history page it serves (`page.readOnly: 'written-by-newer-orca'`: hydration, history
and catch-up resets), the shared client reducer keeps it from the latest whole page, and the
desktop status strip and the phone's composer area say "This chat was saved by a newer Orca, so
it's read-only here. Update Orca to continue this chat."

Every read-only latch the host has is a newer Orca's (its database, a row version, a row kind, a
body kind or must-understand fact), so the reason is derived from the journal's latch, not stored.
The field is optional: older clients ignore it (cross-version test against the newest release's
reducer), and older hosts never send it, so a new client against one says nothing, as today. A
reason this client does not know shows nothing rather than words that may be wrong.

The window-merge helpers move out of the client reducer into their own module.

* fix(native-chat): only a newer build's value goes read-only; damage repairs as before

An older Orca keeps a chat read-only only on evidence a newer build wrote it: a value outside a
closed set this build knows (a body kind, a nested discriminant or literal, a mutation kind), read
off zod's issues. That evidence wins over damage beside it. Anything else that fails (a wrong type,
a missing field, a bad optional value) is damage, repaired as before, so damage no longer freezes
a chat behind an "update Orca" it cannot fix. Drops the per-field droppable/must-understand
policy. A lifecycle mutation's kind is decided before its item id, so a newer kind without one is
kept. The context-usage drop is unchanged from main.

* fix(native-chat): a read-only chat locks its composer and says why there

Removes the separate read-only line (desktop status strip, phone notice component). The host's
`readOnly` on whole pages now feeds the existing composer lock instead: desktop disables the
composer with "Saved by a newer Orca. Update Orca to continue this chat." as its placeholder, and
the phone adds a 'read-only' input-lock reason with the same words. A read-only chat shows no
prompt card it would refuse; the draft stays in the composer. The phone's send-failure line is
back exactly as on main.

* fix(native-chat): a read-only chat pages back through its history

A read-only journal answered every history request with a reset, so a chat this PR now keeps
read-only more often could show only its newest page. Backward reads now serve the snapshot the
open folded, as the first page already does; a forward read of rows still resets.

* test(native-chat): an unknown key in a question entry is read and kept

* test(mobile): the read-only overlay test typechecks

* chore(native-chat): satisfy the changed-code gate in admission and the read-only overlay test

* fix(native-chat): a new value inside a known block or goal arm reads as a newer build's

The open fallback arm of the block and goal unions now aborts, so zod reports the known arm's own
failure instead of only the fallback's; a future closed set there reads unreadable, damage there
still repairs. The schema headers name the context-usage exception and say a new open-string
value must be safe for every older build (rewind keeps only known states; pages carry no row
version).

* fix(native-chat): a read-only chat reconnects for a whole page, so an updated host unlocks it

The client keeps `readOnly` until a whole page replaces it, but reconnected at its cursor and got
only batches, so a desktop attached to a host updated in place stayed locked with "Update Orca".
While it holds the latch it now subscribes without a cursor; the snapshot re-derives the state on
any host version. The phone already subscribes without one.

* fix(native-chat): every desktop write control follows the one read-only fact

The structured session's transport state derives one fact from the page's `readOnly`: the words
for why the host refuses writes. Every write control reads it. While it holds, the chat has no
turn and no work, as the host projects it, so the working row and Stop go away; a pending prompt
stays shown above the composer with its card disabled; queued cards' Send now, Delete and Edit,
the queue's Resume, the goal banner's actions, the model and option pickers, dictation and
background-task Stop are disabled or withheld. The composer placeholder stays the one place the
reason is said. `lockReason` now locks the composer by itself.

* fix(mobile): every phone write control follows the one read-only fact

The phone session derives one fact from the page's `readOnly`, the words for why the host refuses
writes, and every write control reads it: no turn or work while it holds, so no Stop; the pending
prompt stays shown with its card disabled; queued cards and Resume are inert; the model and option
pickers stay shut; the composer field is not editable, so its placeholder keeps saying why, and the
lock applies at once instead of after the transport lock's settle.

* test(native-chat): the newest release hydrates a read-only chat and scrolls back through it

* test(native-chat): a read-only chat reads idle even with a send its provider never answered

* test(native-chat): composer lock test without type assertions

* fix(native-chat): round-3 read-only fixes

- An old /model or option request no longer reopens its picker when a read-only chat unlocks: the
  menu is keyed by the request alone, and a lock only keeps it from mounting open.
- A disabled question card still steps through its questions; only answering is locked.
- A failed send's notice in a read-only chat says only that the message was not sent, with no
  Retry: the composer already says why, and no retry can land. Its wiring moves into
  useStructuredAgentSessionDeliveryNotices.
- The host's background-task stop flags stand; the client no longer overrides them.
- The view reads the read-only fact through one local flag.
- The schema header says what an older build's rewind does with each open string.

* test(native-chat): count picker mounts without an effect

* fix(native-chat): read-only keeps other failures' words and shuts open option menus

- In a read-only chat, only a send the newer-Orca refusal stopped is shortened to "Your message
  was not sent."; any other saved failure keeps its own words, and none offers a Retry.
- A model or option menu open when the lock lands has its items disabled, so it cannot send a
  change the host would refuse.

* test(native-chat): lock-lands picker test uses a typed surface

* fix(native-chat): a locked composer draws its reason

The editor's placeholder used the default that draws nothing while the editor is not editable, so
a read-only chat's composer was empty and its reason lived only in the aria-label. The placeholder
now draws while disabled, and its words are empty unless the composer is locked with a reason, so
every other disabled composer (a pending prompt, no terminal) looks as before.

* fix(native-chat): sync the locked-placeholder flag in an effect, not during render

* fix(native-chat): a read-only chat is not offered for resume or counted as failed to resume

After a relaunch, a chat whose journal this build keeps read-only (a newer Orca's) was listed in
"Resume interrupted chats?", failed with "Orca couldn't resume this chat. Open it to continue
manually.", and left a status-bar "N chats failed to resume" that never cleared, since nothing can
continue a chat this build cannot write. The resume set now skips such a chat after the checks
that end an offer (fork, moved on), so the offer is kept, not spent, and an updated Orca offers it
again; the failure ledger keeps an already-filed failure for it but does not show it. Both read
the chat's open journal, which listing and acting open first.

* fix(native-chat): a refused resume continuation keeps the refusal's reason

A send refused while continuing a chat after a restart was filed with its code alone, so a newer
Orca's refusal lost its `journalWrittenByNewerOrca` reason. The continuation now carries the whole
refusal, as a refusal from the agent's start already did, so the filed failure keeps it.

* fix(native-chat): a newer Orca's chat keeps its resume offer however it is met

- A newer Orca's whole database counts as read-only for resume, so a chat whose journal cannot
  be opened at all (a table the newer schema changed) is not offered, run or counted either.
- The checks made right before sending no longer skip read-only chats: turning one away there was
  read as the user having moved on and deleted the offer. Its send is refused instead.
- Settling a resume files nothing for a newer Orca's refusal; the existing rollback reopens the
  offer for an updated Orca.
- The continuation records the refusal as a reference, without the wire prose.

* chore(native-chat): one import of the session wire types in the continuation

* docs(native-chat): resume and read-only comments match the current rule

* test(native-chat): a closed set of a journal row cannot change without the row version

The test walks the body schema and the row and mutation kind tables, collects every closed set (a
row kind, a mutation kind, each enum, literal or discriminant), and compares them with a snapshot
recorded beside the row version. A new value makes older builds go read-only, so it fails until
the reader ships first or `v` is bumped and the snapshot updated. Tags a catch-all arm accepts as
any string (block types, goal states) are listed apart: older builds read a new one as-is.

* feat(native-chat): a body or plan subject of a newer kind is kept and the chat stays writable

An item body kind and an approval subject kind this build does not know now read through the
same catch-all blocks and goal states use (`openDiscriminatedUnion`), instead of making the chat
read-only. The item is kept, drawn by nobody, and ignored by everything that reads items (turns,
prompts, status); a rewind carries it as it was, kept by its place like every other row. An
approval whose subject this build cannot draw shows its `detail`, which Orca's writers fill with
the subject's text. A sent message of a kind this build does not know stays a newer build's.

* fix(native-chat): rewind narrows a retained body by its kind before normalizing it

* fix(native-chat): one chat that cannot open no longer stops the startup restore of the rest

* fix(native-chat): a damaged chat fails to load and nothing is deleted

A row this build cannot parse, a gap, or an epoch without its first row used to
be repaired on open: every row from the damage on was deleted and a rebuild from
the provider transcript was attempted. The open now fails through one refusal
(failLoadOnJournalDamage, journalCorrupt), every row stays, and a damaged
per-chat file is kept whole and never copied. A newer build's row still wins
and keeps the chat read-only. The body classifier for closed-set values, the
repair marker and disclosure, and journal recovery from the transcript go.

* chore(native-chat): no reset or adapter left on the open's fixtures

* feat(native-chat): an approval of a newer Orca's subject kind can only be cancelled

Desktop and phone show its detail and the line "This request needs a newer
version of Orca.", disable every answer, and keep the card's cancel, which ends
the turn. The chat stays writable.

* test(native-chat): the closed-set guard says a missed version bump fails older builds' load

* test(native-chat): the closed-set guard names what a missed version bump does

* fix(native-chat): a row the reader rejects is never written, and a chat that cannot load keeps its tab

Every journal insert reads its serialized row back with the reader inside the
write's transaction and refuses one it rejects, so Orca's own writer can no
longer leave a chat that fails to load. A restored chat whose open fails keeps
its tab and says why when opened. An epoch named with no rows is founded afresh
again, deleting nothing. The at-rest test now expects a damaged chat to be
refused; the replay gate keeps its 2026-09-11 evidence as it was run.

* fix(native-chat): a newer Orca's approval subject is carried as it was, and its card cancels with or without a turn

The approval subject's type is open, so code that reads a plan narrows first; the
host's prompt bounding carries an unknown subject instead of rebuilding it as a
plan, which threw in every start's stale settlement. A Codex rewind keeps a
newer Orca's item in its place. A whitespace-only tag is damage. The card's
cancel reaches the host without a running turn on hosts that take that. A
provider row the reader rejects ends its turn as interrupted and the next send
works. A guard fails if an approval subject kind is added before clients can be
gated (STA-9262).

* fix(native-chat): a card's cancel sends nothing without a turn again, and rewind keeps a newer row after any held row

The host's cancel request has to name a turn on every version, so the turnless
prompt cancel is reverted on desktop and phone. The rewind merge moves its anchor
for every row the provider still holds, so a newer Orca's row stays after one
whose kind this build does not know.

* fix(native-chat): a card this build cannot answer leaves the composer open, and a send starts a turn

An approval of a subject kind this build cannot draw, raised by a newer host's background agent
while no turn runs, left nothing to press: its answers are disabled, its cancel needs a turn, and
the desktop composer gave the card its slot. A send the host queues waits behind any pending
prompt, so even the phone's open composer only queued.

While every pending prompt is one this build cannot answer, the desktop composer stays open, and
desktop and phone send without asking to queue: the send starts a turn, and the card's cancel then
settles it. A chat a dead run left is unaffected: opening it already cancels those prompts.

* feat(native-chat): a chat a newer Orca saved fails to load and says to update, with nothing to send into

Opening a chat a newer Orca saved (a row kind, batch-change kind or sent-message kind this build does
not know, a newer row version, or a newer history store) used to open it read-only: the history
shown, the composer locked with a reason, every control greyed. Now it fails the load, like a
damaged chat, with its own words: "This chat was saved by a newer Orca. Update Orca to open it."
Every row is kept. The read is final, so the pane stops retrying; reopening the tab reads again.

A chat whose load failed for good (damaged, or a newer Orca's) offers no composer under the error,
on desktop and on the phone, so the failure is said once and no send can be refused a second time.

A restart offer for a newer Orca's chat is spent without a word: no failure filed, nothing counted.

Removed with the read-only mode: the journal's read-only latch and every check of it, the history
page's readOnly field (never released), the cursorless reconnect, read-only paging, the composer
lock and placeholder, the greyed controls, and the resume exclusion.

* test(native-chat): a newer Orca's records open no chat, and a status fake carries its submissions

* test(native-chat): the status fake's cast says what the feed reads

* fix(native-chat): a chat's read that failed for good takes the whole pane, over a loaded transcript too

* test(native-chat): the final-read-failure test names its reasons

* fix(native-chat): a newer Orca's chat keeps its restart offer, and its refused load is logged once

* refactor(native-chat): the newer-Orca chats a restart listing skips live beside the candidate reader

* fix(native-chat): a refused chat load keeps where it failed, so the log names it and a new reason logs again

* chore(native-chat): the reducer's window merge back where main has it, and comments say a newer Orca's chat fails to load

* test(agent-hooks): the rename test's journal fakes carry submissions, as a journal snapshot does

* test(agent-hooks): the rename test's journal fakes say what the status feed reads

* fix(native-chat): Dismiss all ends the restart offers this Orca lists, and keeps a newer Orca's hidden ones

* test(native-chat): a resend against a newer Orca's store answers unknown, and the phone says nothing beside the read's words

This build never opens a chat a newer Orca's database holds, so a resent send id there cannot be
answered from its journal: it answers "outcome unknown", never a refusal and never a made-up
record, with no second delivery and no write. On the phone, a send error left beside a read that
failed for good is not shown; the pane keeps only the read's words.

* fix(codex): stop prompting a Codex restart when only its home changed (#25421)

* fix(codex): stop prompting a Codex restart when only its home changed

A Codex terminal that outlived the move to ~/.codex was blocked behind "This
Codex session is using an outdated configuration" until the user restarted it,
which starts a fresh codex and ends the conversation. That terminal keeps
working on Orca's old Codex home, which is refreshed from ~/.codex, so the
change did not need the user's answer; the prompt also never appeared for
Codex in Git Bash terminals, whose process tree Orca cannot see through.

The restart prompt now covers only an account switch, which the user caused.
The pane record keeps its home route, which the retained-home refresh and the
shared-server check still read; only the prompt and the custom-home downgrade
that existed to keep it from guessing are gone.

* refactor(codex): drop what the home-route prompt left behind

- Record a pane's own CODEX_HOME override as-is. The filter that kept only
  overrides Orca could re-derive existed for the removed route comparison;
  its one remaining reader, the shared-server check, returns null for the
  shared-home route those panes record either way.
- Treat custom-home like shared-home in resolveCodexPaneHome: the removed
  downgrade only wrote it without an override, so it never named a home.
- Inline the restart notice key; its route/account prefix was its only job.
- Delete the two pane-local override tests, including a POSIX-only one that
  still expected custom-home and would have failed on Linux and macOS CI.
- Cover the account recheck branches the deleted route-recheck file was the
  last to exercise: main reporting a pane current, and main not answering.

* refactor(codex): retire custom-home and the last re-check helpers

- Read an older build's custom-home record as shared-home, which it always
  was, and drop custom-home from the route type and every check.
- Delete shellStartupCodexHomeOverrideMatches and its comparison helper;
  nothing re-checks a recorded override any more.
- Build the pane launch record in one return: the route is always set, and
  only a resumed launch differs, in how it picks the account.
- Drop the restart dialog's notice key; its focus effect now depends on the
  pane and both account labels directly.
- Give the account recheck test a typed window stub, so CI's type-assertion
  gate passes, and remove timing entries for deleted test files.

* fix(codex): drop the removed dialog strings main added to es.json

* refactor(codex): stop recording a pane's custom CODEX_HOME

The pane record kept a pane's CODEX_HOME override so the removed route
prompt could re-check it later. Its one other reader, the shared-server
check, only looked at it for a real-home pane, and a custom CODEX_HOME
always routes a pane to Orca's mirror, so it was never used.

Drop both record fields, their validators, equality checks and spawn
plumbing. getCustomCodexHomeOverrideForLaunch folds into the existing
hasCustomCodexHomeOverrideForLaunch, and real-home resolves to ~/.codex.
Records from older builds still parse; the parser keeps only known keys.

The fish test's decoy no longer sets CODEX_HOME, so the boolean check
still fails if the launch env XDG_CONFIG_HOME is ignored.

* test(codex): drop setup the yes/no CODEX_HOME checks no longer need

* feat(agent-launch): keep long prompts off the launch line and paste them after readiness (step 1 of 7) (#24257)

* feat(agent-launch): host-side prompt delivery for agent.launch

The host's agent.launch typed any launch prompt into the shell as part of the
launch command. A long or multi-line prompt then ran line by line in the
shell, and an agent that never showed readiness or crashed at startup had
nothing guarding where its text went.

agent.launch now carries a prompt on the typed line only when the line stays
one line, control-free and at most 512 bytes; otherwise the agent starts
clean and the host pastes the prompt once the agent's own ready signal fires
(bracketed paste plus its composer marker or a quiet render, read only after
the shell's last hand-off, never while the pane's own shell is proven in
front), with main's draft-paste bytes and an Enter 50 ms later. Orchestration
worker starts wait on tui-idle as before. A replay-safe launch admits and
claims its ledger row in one write, Qwen Code gets a second Enter, the
desktop and phone share one launch-refusal classifier, and hosts advertise
agent.launch.prompt-carry.v1.

Split out of #23748, which moves the desktop source-control buttons onto
this path.

* fix(agent-launch): keep a short-lined multi-line prompt on a local zsh launch line, as main did

#24257 moved every multi-line or over-512-byte prompt off the typed launch line and pasted it after readiness. The phone's AI buttons and review notes, whose multi-line prompts main typed whole into zsh, then reached Claude 0.5-3 s later and their RPC reply waited for the paste.

The host now names the shell a local macOS or Linux line is typed into, the way the spawn picks it, and a multi-line prompt rides a zsh line when every line is at most 512 bytes and the whole line at most 8 KB. A real-zsh test types such a line through Orca's own ready barrier and startup write, including when a slow user config makes the write land early. Elsewhere the measured unsafe cases keep the paste: bash 3.2 runs multi-line lines piecemeal, fish drops an early multi-line write, and any shell loses a line over 1 KB written early.

* test(agent-launch): keep the real-zsh launch-line test out of the Windows lane's gate scan

The Windows lane registration check read `const ZSH_PATH = process.platform === 'win32'` (the head of a multi-line ternary) as a Windows-true flag, so `describe.skipIf(!ZSH_PATH)` looked like a Windows-only suite. The file is POSIX-only; the zsh lookup is now a function.

* refactor(protocol): move the agent.launch capabilities into their own module

Main's protocol-version.ts sits at the 300-line cap, so the prompt-carry capability pushed it over. The four agent.launch capabilities and their doc move to agent-launch-runtime-capability.ts, re-exported by name and spread into RUNTIME_CAPABILITIES at the same position; the advertised lists and every export are unchanged.

* refactor(protocol): import the agent.launch capabilities from their own module

`export *` from protocol-version left the four names undefined under the mobile recording loader, which resolves a relative import through a Proxy with no own keys, so 37 phone recordings lost agent.launchReplay. Importers now name agent-launch-runtime-capability directly; protocol-version only spreads its list.

* refactor(agent-launch): drop the unshipped viewMode field and trusted local caller id

Both were inert in step 1 and existed only for step 2. agent.launch will become a
public plugin API, so every wire field is permanent once shipped; a top-level
viewMode reads as "choose terminal vs chat", which the host decides. Step 2
introduces placement and view intent under a placement object instead.

* fix(agent-launch): read Codex's provisional startup from the rule files' hold anchor

Main (#24375) moved Codex's provisional-header check into codex.json's
provisional_startup hold anchor and deleted codex-terminal-readiness.ts, so the
launch readiness hold now asks showsHoldAnchor, as main's own settled check does.

* fix(agent-launch): hold rule-file name titles to quiet for a launch, and census the zsh fixture

Main (#24375) answers a name-only title from each agent's rule file ahead of the
sustained-title lane, so gemini.json's name_title settled a launch readiness wait
on the shell's auto-title while Gemini was still booting. A launch now asks quiet
of every weak idle verdict, as that lane did.

Main's readiness census requires a recorder for every runtime fixture; the zsh
prompt recording is a non-agent control. Gemini's synthetic baseline is
regenerated for this PR's stated change: a bare gemini title is no longer its
rest mark, so name-only rows settle weak, and a fresh working or blocked status
is no longer overridden.

* fix(agent-launch): paste a launch prompt only when the launched agent is proven in front

A launch pasted its prompt unless a shell was proven in the terminal's
foreground, so any read that could not prove one let the prompt through. After
an agent exited at startup, its shell turned bracketed paste on at the next
prompt, readiness fired on it, and the prompt was typed into the shell:

- macOS: a pane runs its shell under login, so the process-group fence's root
  was never the shell's group and never proved it; the cached foreground name
  could also still name the exited process.
- Windows Git Bash and WSL: the shell-alone-in-its-job check never answers.

Now one fresh read of the terminal's foreground decides: agent, shell or
unknown. Only 'agent' lets a write through (paste, Enter, second Enter, reused
panes too); 'shell' still drops a ready signal. A Windows host never proves the
agent, so there the launch line carries the prompt at any size, as on main.

* test(agent-launch): cover the Windows QA stub, a grok override that exits at once

* fix(agent-launch): keep the local socket alive while a prompted launch waits for its agent

A launch with a prompt now waits up to 60 s for the terminal agent to be
ready before it writes the prompt, and reports not-delivered when the agent
never is. The local runtime socket closes a connection idle for 30 s unless
the request is a long poll, so a launch whose agent exited at startup lost its
reply and the caller saw 'runtime closed the connection' instead of
not-delivered. Classify a prompted agent.launch and agent.launchReplay as a
long poll, as orchestration.workerStart already is for the same wait.

* refactor(agent-launch): narrow the launch params by 'in' instead of a cast

* fix(agent-launch): find a launched agent behind a wrapper that leads its process group

A tcsh or nu launch line runs the agent from /bin/sh '<script>', and a
wrapper script that does not exec its agent does the same: the wrapper leads
the terminal's foreground process group and the agent is a member of it. The
fresh foreground read names the group's leader, sh, so a prompted launch was
refused or pasted late (M4Air tcsh: 2 of 4 not delivered, 2 pasted ~9 s late).

Before that read, take the host's process-group observation as positive proof
when it names the launched agent among the foreground group's members and is
younger than a ready signal's quiet window. It never proves a shell.

* fix(agent-launch): judge the foreground-group proof by when its capture began, not how long ps took

The age the host stamps on a process-group observation runs from the start
of its whole-machine ps, so on a loaded Mac a capture begun after the read
was asked for still read as older than 1 s and the proof was dropped. Count
an observation whose capture began after the read was asked for, less the
window a shared capture is reused across.

* test(agent-launch): keep the crash-guard live test out of the Windows lane's gate scan

The Windows-lane registration scan read the const assigned from a platform
check as a Windows-only gate, though the suite runs everywhere but Windows;
find zsh in a function instead, as the real-zsh typed-line test does.

Under load the fresh foreground scan can fail to answer, which lets the
shell's prompt settle readiness (2 of 4 paired runs). The guard still refuses
that write, so assert the refused write, the property that must always hold.

* perf(agent-launch): read a local pane's foreground from its own terminal, not the whole process table

The foreground read that gates every launch paste ran the daemon's
inspectProcess capture and then a fresh scan, each a whole-machine ps; the
fresh one also waits for any capture already running before it starts its own.
Measured here at load 5: 1.2 s a read (M4Air QA: 3.4-5.0 s, and worker starts
17.6-32 s against main's 9-12 s at load 25-84).

On a local macOS or Linux host, take the pane's root pid from the provider's
session inventory and run one ps limited to that pane's terminal. Its
foreground process group decides: the launched agent or any non-shell member
is the agent (a wrapper that did not exec its agent leads the group), a group
of shells alone is the shell. Same pane, same verdict: 2.7 ms a read. SSH hosts
keep the relay's observation and name.

* test(mobile): re-measure the web app's script sweep after agent.launch's capabilities moved out of protocol-version

The mobile web bundle check failed at 124 assets against a ceiling of 123. Main already sat
exactly on that ceiling: its sweep table read 69 scripts at 16 routes while the tree builds 73,
the whole margin of 4. This branch imports the agent.launch capabilities from their own module,
so protocol-version is no longer pulled into the root layout and four other routes. That moves
which routes share which modules, and the Qoder capability module, imported by protocol-version
and the AI-vault resume path, no longer shares an importer set with anything, so it gets a chunk
of its own: 74 scripts.

The fence says to re-derive the bound rather than raise it, so the sweep is re-measured on this
head (every prefix of the sorted route list). The worst route now adds 10 scripts (session), not
9, which moves the pinned shell crossing from 32 to 30 routes; main re-measured on its own lands
on the same crossing.

* fix(agent-launch): a worker's brief needs its agent found in front, and Grok's start answers on its composer

A paired-server worker start whose agent exited at startup typed its brief into the server's
shell, which ran it: the idle wait can settle on a shell back at its prompt, and the brief was
written with no foreground read. Both worker-start paths now check before each brief write, as a
launch prompt is checked: on a host that can find the agent in front it must be there; on one that
cannot (Windows) a shell proven in front still refuses, and anything else writes as before.

A Grok worker start waited ~10 s more than main: its only rest signal is its bare name, which a
launch holds to quiet output, and Grok animates its logo for ten seconds after its composer glyph.
A worker start for an agent whose rest signal is its bare name and whose composer draws a marker
(Grok, DSH, mimo-code) now also answers on that marker, whichever comes first.

* fix(mobile-chat): a failed message's text is added to the draft, and an expired resend no longer blocks that text (#25149)

* fix(mobile-chat): a returned message is appended to the draft, and an expired resend id is spent

* test(mobile-chat): leave the idempotent append to the shared rule's own test

* docs(native-chat): say a whitespace-only draft counts as empty

* docs(mobile-chat): don't overclaim where returned text survives

* feat(native-chat): answer /context in chat view for OpenClaude and OMP (#22294)

* feat(native-chat): answer /context in chat view for Claude

Over a terminal-backed chat, Claude's /context paints a grid only the hidden
terminal sees and records nothing in the transcript, so the chat showed
nothing. The chat host now answers it itself: the transcript decoder keeps
each assistant response's API usage and model, and the composer replies with
the same estimate the CLI statusline shows (input + cache tokens against the
model's window) instead of typing the command into the PTY. The command is
also listed in the curated Claude catalog so the slash menu offers it.

* fix(native-chat): only state a /context window the host can establish

The /context answer sized the window from the transcript's model id, which
never carries the [1m] suffix, so a 1M session read as 200k (e.g. 450k / 200k,
225%). The window now comes from the session's tracked model resolved through
the host CLI's own model listing (the resolvedModel field the list_models probe
already returned), and only a [1m] id that matches the model the transcript
last answered with is sized; anything else reports the used figure alone.

Also:
- Offer /context only in the desktop terminal-backed composer; the shared
  catalog is mobile's too, and mobile cannot answer it.
- Answer a typed /context even with images attached, as the picker does, and
  keep the attachments armed instead of sending them to the terminal.
- Report nothing until a response lands after a /compact or /clear sent from
  the chat, instead of the pre-compaction size.

* test(native-chat): pin resolvedModel through Claude model discovery

* fix(native-chat): say /context is unavailable when the host never reports usage

A host that predates usage decoding, or a scraped view, decodes Claude's
replies without a model or usage, so the chat promised an answer after the
next response that would never come. Once the agent has answered and no
answer names its model, say usage is not available for this session.

* feat(native-chat): answer /context for OMP instead of Claude

Claude and Codex answer /context themselves in the structured chat lane, so
the terminal-backed Claude answer, its [1m] window rule, and the resolved-model
plumbing through the model listing go away.

OMP's /context only paints a panel inside its TUI. The OMP decoder now keeps
the provider, model and usage of each reply (none for aborted or errored
replies, which OMP's own gauge skips) and turns compaction rows into the
existing compaction boundary. The OMP model listing keeps each model's
context window, and the chat answers /context from the last reply's prompt
size against the window of the provider/model that served it.

* feat(native-chat): show OpenClaude's own /context report in chat

OpenClaude writes its /context grid to the transcript as a
<local-command-stdout> row, which the chat hid as harness noise. The live
message preparation now turns the stdout row that answers an opted-in command
(/context for OpenClaude) into command output with the ANSI colors stripped,
and the notice row renders command output in monospace so the grid keeps its
columns. Replies to other local commands stay hidden, and Claude is not opted
in. OpenClaude's slash menu now lists /context; Claude's does not.

* test(native-chat): pin OpenClaude /context output through live message preparation

* test(native-chat): pin the OMP context window through model discovery

* test(native-chat): pin monospace rendering of command output

* test(native-chat): restore the notice row suite the command-output test replaced

The previous commit rewrote NativeChatNoticeRow.test.tsx wholesale, deleting
main's compaction, tone, plan, provider-notice and old-reader coverage. Restore
it and pin monospace command output through the message row instead.

* fix(mobile): keep OpenClaude /context off mobile, which cannot show its report

The shared slash catalog now lists /context for OpenClaude because the desktop
chat surfaces its transcript reply. Mobile's transcript fold does not, so the
command did nothing there. Mobile now offers the catalog minus commands answered
only by a surfaced reply, which returns its OpenClaude menu and send
classification to main's behavior.

* refactor(native-chat): drop the unread estimated flag from context usage

Left from the earlier design; the answer text states the estimate itself.

* fix(native-chat): keep /model replies hidden after an OpenClaude /context

Skill surfacing ran first and rewrote non-catalog envelopes such as /model into
plain user text, so command-output pairing no longer saw them. A later /model
reply then paired with the earlier /context envelope and appeared in the chat.
Pair outputs against the raw envelopes before skill surfacing.

* fix(native-chat): word the OMP /context answer for a compacted session and show it as an aside

After a compaction the agent has already answered, so the unknown-usage
line now promises the next response instead. The host answer is one
sentence, so it draws as the muted line it replaces rather than a
monospace grid. The provider/model selector now comes from one helper
shared by the OMP listing parser and the answer, and new tests drive
real OpenClaude and OMP transcript lines through the decoders.

* refactor(native-chat): pair command replies by row link and declare /context replies on the catalog

A `<local-command-stdout>` row now answers the command row its `parentUuid`
names, carried on decoded messages as the optional `parentId`, instead of the
newest command row at or before its timestamp. A reply with no loaded linked
row (older host, command outside the tail window) stays hidden.

How each agent's `/context` is answered is declared once, as `reply` on its
catalog row (`composer` for OMP, `transcript` for OpenClaude). The slash menu,
the composer's answer, the transcript surfacing and the mobile catalog all
derive from it, and both send paths share one intercept. Mobile no longer lists
OMP `/context`, which did nothing there.

* perf(native-chat): skip command-output surfacing for agents that declare no transcript reply

Every Claude-format row now carries its parent link, so once a session holds any
local-command reply (/model, /compact) the surfacing pass built a map of every
message on each live update and changed nothing for agents like Claude. Agents
whose catalog declares no transcript reply now return before the scan.

* fix(native-chat): the agent's exit ends its record, and an unconfirmed stop is joined instead of held (#24862)

* fix(native-chat): a child's root exit is reported even during its close, and bookkeeping after it never reads as unproven

- Both connections report the root process's exit once, with `expected` set when a close had
  begun. A close that came back unproven and whose root exits later is finished by the adapter,
  and its end reaches the host like any other.
- A Claude close whose resume-point write fails after the exit was proven, and a Codex close whose
  terminal row is refused, now end the session and report the failure, instead of keeping a dead
  child indexed as if its exit were unproven.
- A Codex close whose forced tree kill can't prove the descendants gone but saw the root exit
  reports the descendants and counts the root exit.
- Every child exit with an identity, expected or not, is forwarded to the host.

* fix(native-chat): the exit ends the child's record; an unfinished stop is the child's own close, which everyone joins

- The host keeps no stored "stop still owed" record any more. A stop begins the child's close
  (`child.close`), which lives on the child and ends with it. A second Stop, the idle reaper,
  quit, a send and an option/answer/goal/rewind all join that close instead of retrying a
  separate obligation.
- A caller waits on the close only as long as the step deadline; the close itself is never
  abandoned. A proof that lands after every caller stopped waiting reaches the host as the
  adapter's report of that exit, which ends the record through the same handler.
- Once the exit is proven, draining, settling, the lease release and the adapter's
  acknowledgement are each attempted and reported on failure; none keeps the child on record.
  A start, and the handle's close, write a release that failed from this host's proof of that
  exit, so a failed write never refuses a send.
- A start that meets a close still unverifiable is refused with `previousExitUnverifiable`, so the
  queued message is rejected with a send-again reason; nothing is held and nothing starts beside
  the old process.
- The idle sweep goes back to idle reaping only.
- Removes #24333's retry entry points, the wait row and its hold rule, the ask/failure cursors on
  the stored record, and the stop's own wake.

Tests replace the #24333 unproven-stop test: a send joining an unproven close and an in-flight
one, a late proof past the caller's bound, a root exiting after its close gave up, a proven exit
whose resume-point write and lease release both failed, an unverifiable close rejecting the send
and refusing an option change, a surviving descendant, quit and the idle reaper; and Codex's
unverifiable, late-exit and joined-close cases.

* fix(native-chat): a message refused because the old process's exit is unverifiable says so, and to send again

The start failure for a refusal with reason `previousExitUnverifiable` reads "Orca couldn't
confirm Claude's previous process ended. Send your message to try again." instead of "Claude
couldn't restart." The status-row kind and the refusal reason stay in the shared lists for rows
and hosts that still carry them; the catalogs keep one sentence for both.

* fix(native-chat): a close's verdict is the root's exit alone, and what follows it is logged

- A Claude close resolves as soon as the root's exit is proven: the session ends and its `ended`
  report goes out then. Saving the resume point runs afterwards and a failure is logged, so a slow
  or hung write never reads as an unproven exit or keeps a dead child on record.
- A root that exits after its close came back unproven finishes that close through the same path
  as any close, so the session's child work is published as ended (background tasks and subagents
  no longer stay shown running for a dead agent), and a failure there is logged.
- Codex logs a refused final row, and reports a root exit whose forced tree kill could not prove
  the rest of the tree gone the way Claude does, so the host logs it and blocks nothing.
- Both adapters take the host's logger for this bookkeeping.

* fix(native-chat): one handler ends every child's exit, and a join waits on the adapter's own close

- One exit handler (`structured-agent-session-child-exit`) ends a child's record for an exit
  expected or not. `expected` only changes what the chat is told: the stop's cause, its end at the
  stop's ask, the settlement id, and no crash outcome row. The lease release keeps the exit's
  evidence; the handoff guard, lifecycle barrier, sink release and adapter acknowledgement apply to
  both. A Claude journal-sink failure ends in the same step as its stop, as Orca's own fault.
- Joining a close is asking the adapter, whose close is memoized while it runs and bounded by its
  own kill escalation; the host keeps no attempt of its own and no 10 s caller bound. An ask after
  a close came back unproven runs the stop again.
- A close's end is stamped where its stop was asked for (a repeated ask moves it), so the closed
  chat and failed start checks order a message accepted meanwhile after it.
- A start refused because the old exit is unverifiable rejects what was queued in the same step.
- The end of a close the host asked for no longer waits on the cross-session recovery chain.
- The kill no longer waits for the stop event's write; the journal writes rows in order.

* fix(native-chat): an exit's lease release lands whatever the length of its reason

A crash's reason can carry kilobytes of the provider's stderr, and a lease whose death detail is
over 512 characters fails the store's own check. The exit handler cut it, but the release a start
or the chat handle's close re-derives did not, so after a crash whose own release failed every
message was refused as not resumable until restart. The record's builder now cuts the detail to
the record's bound, so no writer can hand it one too long.

* fix(claude): a proven close waits at most 2 s for the output it already wrote

Once the root's exit is proven, the close still waited for the SDK's output reader to end. Something
outside the process tree that holds the output open would keep that close, and every send, Stop
and quit joining it, waiting with no bound. The wait is now bounded; past it the close resolves as
proven and the open output is logged.

* fix(codex): an exit reported inside Orca's close keeps the reason Orca closed it for

The connection reports the app-server's exit inside the close that ends it, so that report ended
every Codex close and replaced the close's own reason (for example, a provider frame that could not
be recorded) with the connection's stderr text in the ended record and the lease's exit evidence.
The session now records Orca's close with its reason, and the exit it ends keeps that reason. The
test connection reports its exit inside close the way the real one does.

* fix(native-chat): quit stops delivery before it drains exit recovery

Every exit now wakes delivery, and teardown drained exit recovery before it stopped delivery, so an
exit settled in that window could start a fresh agent that teardown then killed. Teardown stops
delivery first; queued messages wait for the next launch.

* docs(native-chat): the unverifiable-exit refusal no longer names a caller's wait

The caller's bounded wait was removed; the comment describes the close as it is now.

* fix(native-chat): a stop whose kill did not take is logged, and the next ask kills again

When a close's kill leaves the agent's root running, the host now logs it. Tests pin what a later
ask does: each connection runs its whole stop again (Codex sends SIGKILL a second time), refuses
input meanwhile, and proves the exit once the kill takes.

* fix(native-chat): a start refused over the old process says Orca couldn't stop it

The host reaches an unverifiable verdict only after its own kill left the agent's root running, on
the machine that runs the agent, so the sentence now says that: "Orca couldn't stop {agent}'s
previous process." The refusal reason, failure kind and wire shapes are unchanged. The host test
also checks the failed kill is logged.

* docs(native-chat): an unverifiable close verdict is a root that survived the kill

The host's close runs where the agent runs, so lost contact never yields this verdict; the comment no longer says it does.

* fix(native-chat): a kill that did not take is reported once, by whoever met it

The log added at the close fired beside a Stop's own failure report for the same event. A stop
still reports it through its failure; a send or option change refused over it now logs it at the
refusal, the only place it is otherwise invisible.

* test(native-chat): a second Stop joins a close the first could not prove and retries its kill

* fix(native-chat): say a start refused beside an unstopped process plainly

The rejection now reads "Couldn't stop {{agent}} from before. Send your message again to try once more."
This kind has its own send-again step; every other failure keeps "Send your message to try again."

* feat(activity): filters, matching header, row right-click menu, and stay in the activity view (#25376)

* fix(sidebar): stop workspace reveals from leaving the activity view

Reveals are skipped while the activity view is showing, and activation no
longer lifts workspace-list filters there. Only explicit requests (Go to
workspace, reveal-current-workspace, Cmd+J project row, agent send target,
Cmd+1-9) switch to the workspace list via showSidebarWorkspaceList.

* test(sidebar): keep test harnesses out of the sidebarBody writer census

* feat(activity): workspace-origin filters and a matching options trigger

Activity view gains its own persisted Hide automation-created, Hide CLI-created
and Hide other-client agents toggles, applied through the existing activity
scope filter so the selected-row exemption and identity-preserving return keep
working. The options trigger now uses the workspace view's SlidersHorizontal
icon and shared numeric badge, counting every active activity filter, and Add
project stays visible so no header button shifts between views.

* feat(activity): right-click menu on activity rows

Open, Mark as read/unread, Go to workspace (real workspaces only), Copy (agent
title, plus branch and path for real workspaces), and Clear from list for
finished threads, reusing the row's existing actions and clearActivityThread.

* fix(sidebar): leave the activity view only once activation commits

Go to workspace and Cmd+1-9 switched the sidebar before activating, so a
blocked folder activation still left the activity view. Activation now owns
the switch via showWorkspaceList, applied after its failure gates. The
separate showSidebarWorkspaceList action and the one-line sidebar-body-reveal
module go away: setSidebarBody is the single writer, and the census pins its
callers.

* fix(activity): close the row preview when its right-click menu opens

* fix(activity): keep the row preview closed while its right-click menu is open

* fix(ui): give right-click menus the same solid surface as dropdowns

* fix(activity): match the agent row menu to the workspace row menu

* fix(activity): offer the same copy items as the workspace row menu

* Add confirmed deletion of nested worktrees (#25668)

* Preserve complete SQL checkpoints before updates and align restart coverage

 Old profiles may upgrade directly; no intermediate release is required. A copy
 source can still be read as JSON, but every profile changed by a transfer or an
-offline settings command must first establish SQLite authority.
+offline settings command must first establish SQLite authority. The original
+JSON remains unchanged after import and may be much older than SQLite.
 
-Clean shutdown and maintenance refresh compatibility JSON for older builds. A
-crash or failed export can leave an older snapshot. If an older build edits that
-file, startup refuses to choose silently between it and SQLite. The explicit
-`orca profile state rollback --current-json` command selects those edits and
-archives both copies; it does not merge divergent histories.
+Before using a JSON-only build, stop Orca and run the current bundled CLI's
+`orca profile state rollback --latest-json --profile-id <id>` for each profile.
+Omitting `--profile-id` selects the active profile without changing the index. It exports the latest committed
+SQLite state and selects that JSON after archiving the current database and
+recovery artifacts. Do this on the machine that owns the profile, including SSH
+hosts. An interrupted command preserves recovery evidence; inspect
+`orca profile state exports` and select the retained `--revision` to retry after
+the database has been removed. The in-app updater refuses releases below v1.4.214, the first stable SQLite
+release, including pinned and local builds. Install a JSON-only build manually
+only after converting every profile. Older SQLite-capable builds still require
+a compatible database schema.
 
-Keep import and recovery while old profiles or backups remain supported. Removing
-automatic compatibility exports is a separate compatibility decision requiring a
-policy for older builds and recovery when a database is missing. Deleting the
-ordinary JSON writer does not justify deleting these safeguards.
+If an older build has already edited JSON separately, startup refuses to choose
+silently between it and SQLite. `orca profile state rollback --current-json`
+selects those edits and archives both copies; it does not merge divergent
+histories. `--current-sqlite` keeps SQLite authority and explicitly republishes accepted
+JSON; `--latest-json` converts SQLite state for a JSON-only runtime.
 
-SQLite admission, transactions, row serialization, backups, and recovery command
-dispatch stay in the parent folder. In particular, JSON payloads in SQLite are
-its document representation, not a legacy file backend. Profile-index metadata,
-move journals, caches, wire messages, and external-tool settings are also outside
-this boundary.
+The durable `profile-state.db.authority` marker records that SQLite was
+established, even before the first backup. It prevents missing SQLite from
+silently reviving stale JSON or creating an empty profile. Only explicit JSON
+recovery removes it, after publishing the selected state and archiving evidence.
+Keep complete profile directories when moving or restoring them; deleting every
+artifact proving SQLite existed defeats any missing-database check.
+
+Keep direct import, old-backup reading, explicit exports and recovery while old
+profiles or backups remain supported. They are independent of automatic JSON
+snapshots. SQLite admission, transactions, backups and recovery dispatch stay in
+the parent folder. Profile-index metadata, move journals, caches, wire messages,
+external-tool settings and JSON documents inside SQLite are unrelated formats.

Subject: [PATCH 028/167] fix(i18n): polish Japanese onboarding checklist copy
 (#19035)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* feat(i18n): localize onboarding checklist steps to Japanese

Add Japanese translations for the 16 setup-checklist step names and
descriptions (`auto.components.feature.wall.feature.wall.setup.checklist.
localized.copy.*`) that were still falling back to English in the Setup
Guide modal and settings pane, and extend the checklist copy test so the
Japanese catalog is guarded alongside Korean.

* fix(i18n): render Multi-task as 並列開発 in the Japanese setup checklist

並列 is the term Claude Code's Japanese docs ("並列セッション"), Cursor's
Japanese coverage ("並列エージェント"), and the Zenn/Qiita worktree
articles use for running several worktrees or agents at once; 並行 was
the outlier.

* test(i18n): assert setup checklist catalog values are strings

* fix(i18n): align the Setup Guide subtitle with 並列 in Japanese

The subtitle sits directly above the 並列開発 step in the same modal and
the Korean catalog already renders "parallel agent work" as 병렬; use
並列 in Japanese too so the modal does not mix 並行 and 並列.

* fix(i18n): reconcile Japanese checklist copy with current catalog

Subject: [PATCH 029/167] fix(native-chat): keep a Stop's note with the turn it
 waited for and stopped (#25056)

* fix(native-chat): a Stop binds only the turn it actually stopped

A Stop pressed before any turn showed used to claim, at end-write time,
whatever turn the stopped send later opened, even when the Stop stopped
nothing. A turn that then died on its own read as "Interrupted" (your
cancellation) instead of "Failed".

Now a person's Stop that named no turn binds, in memory only, every turn
that ends while the Stop settles, and afterwards only the turn its
interrupt took. The settle ends a still-running stopped turn once. A
relaunch finds nothing in memory, so an unsettled turnless Stop binds no
turn. A Codex Stop whose answered turn does not open within its wait, or
whose send's answer was lost, now answers refused, so the host ends the
child and the turn can never run.

* fix(native-chat): keep the person's queue pause and close binding after a Stop settles

A host stop or eviction with no turn running now defers to a person's
Stop while its queue pause still holds with nothing sent since, read from
rows, so a held card is not handed off on reopen after a Stop that did
nothing or whose kill failed.

A person's close that named no turn opens a settle around its child's
end, so a turn that end cuts reads as theirs.

A press opens its settle only when the latest Stop event is its own or
the one in force it repeats: a late Stop, a card's interrupt or a lost
event row reopens no earlier Stop.

A Codex Stop that cannot reach a turn still able to open says the Stop is
unconfirmed rather than that no turn ran, and a second Stop still reaches
a turn an earlier wait left unopened.

Also drops the unused openedBy plumbing and the unreachable "a written
cancellation stays one" rule, and pins a relaunch after a named Stop.

* fix(native-chat): a Codex Stop agrees on both presses when a turn is still owed, and pin the close's settle

A Codex Stop that waited for a turn Codex answered a send into now answers
"may still open" whenever that turn neither opened nor ended and its send
is still owed, however the wait ended (it ran out, or the thread went
idle). Before, a first press after an idle thread said no turn was
running and kept Codex, while an identical second press ended it.

Adds a test that a person's close the conversation outlives (as /clear
does) closes its settle, so a later turn that ends on its own reads as a
failure.

* test(native-chat): a Stop whose event row failed binds no turn to an earlier Stop

With one ordered journal writer the Stop's event is in the fold when its
write returns, so the press reads whether it owns the latest Stop from the
fold instead of awaiting the write. Pins the case the read must refuse.

* test(native-chat): name the settle, not a stream drain, in the Stop's own-end test

* test(native-chat): a Codex Stop answered before Codex ends the turn reads interrupted throughout

Codex answers an interrupt it took before it sends turn/completed (interrupted):
on TurnAborted the app-server answers pending interrupts, then ends the turn, on
one channel. The test fake did the reverse. It now answers first and ends the
turn on a later read, and the tests that read the turn's end right after a Stop
wait for it.

New end-to-end test through the shipped host, journal and Codex adapter: with
the real order, every end row of the stopped turn reads interrupted by the Stop
(named, unnamed, and a Stop pressed while turn/start was in flight). Breaking the
settle window turns the in-flight case red: the Stop's own end row then has no
verdict, which reads as failed until Codex's end lands.

* fix(native-chat): a Codex Stop interrupts a turn Codex answered but has not opened at once

A Stop that named no turn, made after Codex answered a send but before the turn
opened, used to wait up to 5 s for the turn to open before interrupting, and
ended the Codex process when it didn't. The stated reason, that Codex refuses an
interrupt until it opens the turn, holds only part of the time: with no turn
active, Codex takes an interrupt once its thread runs (turn_interrupt_inner),
and refuses it with -32600 "no active turn to interrupt" before that or once
the turn has ended.

The Stop now sends the interrupt at once. Only on that refusal, while the turn
has neither opened nor ended, does it wait for the turn to open (bounded at
5 s) and send it once more. A turn that ended meanwhile was nothing to stop. One
that never opens, or that an earlier wait already gave up on, fails the Stop,
and the host ends the child as before. Sends still wait for the turn to open
before steering into it.

The test fake models Codex taking an interrupt once the thread runs (run()).

* fix(native-chat): every Codex Stop waits for an answered turn to start, as the first did

A Stop whose interrupt Codex refused as finding no active turn skipped the wait
when an earlier wait, a Stop's or a send's, had already given up on that turn.
Every press now waits its own bound and retries once if the turn starts, so a
turn that opens during a later press is still stopped. Both presses still reach
the same verdict when it never starts.

* fix(native-chat): a Codex Stop that ends the child before any turn opened withdraws its send

A Stop on a Codex turn that was answered but never opened ends the Codex
process. That end settled the send as in doubt (unknown, recovered), and the
client's outbox holds every later send behind a send in doubt until the person
presses Retry, which re-sends the very message they stopped. The chat looked
stuck.

Codex records a prompt only once its turn has started, so a send whose turn
never opened never ran. When the Stop's refusal says so (turnMayOpen), the child
end now settles the unanswered sends as withdrawn, the verdict Codex's own
interrupted-turn end already gives an unechoed send. The flag rides on the owed
wind-down, so a retry after a failed child end withdraws them too. Claude's
child end still leaves its unanswered send in doubt.

* fix(native-chat): derive the withdrawal of a Codex send whose turn never opened

Replaces the flag the Stop carried to the child's end, and its copy on the owed
wind-down, with a reading of the journal at the settlement that lands. A Codex
child's unanswered send is withdrawn when a person's Stop is in force since it
was sent and no turn row ran, or was written, after it; any other end (a turn
that opened, a host's close, a crash, Claude) still leaves it in doubt. A
retried wind-down reads the same rows, so it withdraws the same sends.

* fix(native-chat): keep a send in doubt when a turn was open for it

The derived withdrawal read a turn as open for a send only if it still ran or
was written after the send. A send steered into a running Codex turn whose
interrupt failed met neither once the adapter's end settled that turn ahead of
the host's settle, so it read withdrawn, though Codex drains a steer into the
running turn and may hold it. A turn that ended after the send was handed over
was open for it too: such a send stays in doubt, as before.

Pins that case, and that a send made after the Stop, to a child that then dies
before its turn opens, stays in doubt.

* fix(native-chat): withdraw a Codex send by whether it started its own turn, not by timing

Whether a turn was open for a send was read from end times: a turn that ended
after the send's handover counted. A send made while a Stop ended the turn is
handed over once that turn reads ended, yet Codex's own end for it can arrive
later, so such a send whose own turn never opened read in doubt again, and the
chat's queue held behind it.

The handover already records where the send went: its message joins the turn
running then (a steer) or belongs to no turn (it starts its own). Only a send
that started its own turn, with none opened since, is withdrawn; one that
joined a running turn, or has no recorded place, stays in doubt.

The Codex test fake takes an answered interrupt as Codex does, dropping the
turn before its end arrives.

* fix(native-chat): leave no Stop row when the Stop took back a send that never ran

A Stop on a Codex send whose turn never opened ends the child, and the child's end
takes the send back into the composer. The Stop still wrote "Cancellation
requested." at the conversation level, so with the send gone it sat under the
previous finished turn and read as if that turn had been stopped. A Stop that found
no turn running and whose child end took back every send it found now writes no
row; a Stop of a running turn, or one that leaves a send in doubt, still does.

* fix(native-chat): keep a Stop's note with the turn it waited for and stopped

A Stop pressed while Codex was still opening the turn read the note's place
before it waited: no turn was running yet, so "Cancellation requested." became
a loose conversation row, never folded with the turn, drawn below whatever came
next. Once the interrupt takes a turn that opened during that wait, the note is
now scoped and keyed to that turn, as a normal Stop's is. A refused or
unconfirmed Stop, and one that writes no row, are unchanged.

* fix(native-chat): key the Stop's note by the turn the interrupt took

* fix(native-chat): count a send whose answer was lost when a Stop takes it back

The no-row rule counted only pending sends, but the child's end also takes back a send this process left in doubt when Codex's turn/start answer was lost. That case still wrote "Cancellation requested." under the previous turn. Both now read one predicate, so they cannot drift apart.

* test(native-chat): pin which sends a Stop's child end can take back

A send an earlier process left in doubt is never withdrawn and never holds the row back, and a queued card's send is never counted.

* test(native-chat): read the outbox reconcile from where main moved it

* fix(native-chat): mark a chat whose start failed on its tab and workspace row

A chat whose start the host refused said so only inside its own tab. Its
row now carries the failed verdict the host publishes for a refused start,
so the tab and the workspace row show it from elsewhere until a retry
starts it or the tab closes. The + menu no longer shows a failed start as
still starting, so launching the agent again retries it.

* fix(native-chat): date the failed-start mark by the failure; keep the + menu change for a separate PR

The failed-start mark on a chat's tab and workspace row is now dated by when
the start failed, the way a failure the host reports is dated: it ages out on
the same schedule, a restart does not bring an old mark back, and a failure
the user already saw stays read. The failure time is saved with the launch
record so a restart keeps it; records saved without it fall back to the tab's
creation time.

The + menu change (letting a failed agent be picked again) moves to its own
PR: its correct form makes a new chat instead of retrying the failed one,
which changes how launches join.

* test: name the local host on the saved failed-launch record

* fix(native-chat): re-check an unconfirmed chat start when its host is reachable again

A chat create whose reply was lost, or that a reload interrupted, stayed unknown until the
user pressed Retry in its tab. Each host subscription opens with one full inventory; on it,
every launch that host owns whose outcome is unknown (including ones restored from the saved
launch record) is re-checked through the existing Retry path, so it settles to started or
failed. One still unknown waits for the host's next return; cancelled launches are skipped.

Subject: [PATCH 031/167] fix: restore main's lint and localization checks
 after the nested-worktree delete dialog (#25684)

* fix(i18n): add the nested-worktree removal strings to the English catalog

#25668 added DeleteNestedWorktreesDialog and its preserved-branches toast
with translate() keys under worktree.nestedRemoval, but not the matching
en.json entries. verify-localization-catalogs and -extraction now fail on
main, and on every PR that merges it. Entries generated by the catalog
sync script from the code's own fallbacks.

* fix(sidebar): import worktree removal types once

#25668 imported from shared/worktree/removal twice in
delete-worktree-failure-toast.tsx. The whole-tree lint gate
(no-duplicate-imports, --deny-warnings) fails on it for main and every
branch that merges main.

Subject: [PATCH 032/167] feat(relay): drain pace window as a reviewed same-cap
 input, with drain-aware 503 gates (#25639)

* feat(relay): drain pace window as a reviewed same-cap input, with drain-aware 503 gates

The same-cap roll drained every cell over a fixed 300 s window, so a US roll
re-placed hosts at ~2/s and spent ~10 minutes draining and waiting for quiet.
The window is now a dispatch input from a closed set (300000, 60000, 30000),
defaulting to today's 300000.

- Below the default is refused for anything but US general cells; Asia drains
  are bound by their targets' accept rate, and migration-only cells hold no hosts.
- A non-default window must be named in the confirmation, the canary authority
  records it (v2), and a batch may run at its canary's window or slower only.
- Each cell job re-checks the window, scales the restart-safe timeout with it
  (15-min lease + window, unchanged at the default), and records what the cell
  applied and when it settled.
- The report-only shadow gate takes the director's drain-return deferrals out
  of the 503 count (window and baselines), adds the rung's 5-min non-drain 503
  budget and a Retry-After check, and reports the measured re-placement rate.
- relay-workflows.md documents the pace ladder and what each rung records.

* fix(relay): judge paced drains on counted 503s against the pre-drain minutes, and seal the canary's pace verdict

Review of #25639 replayed the shadow gate: it read 10-01 c29 as unverified (the
log read stopped at 20k entries), false-blocked 10-02 c22, and was blind on four
cells whose 24 h/48 h baseline held an incident.

- Director 503s now come from Cloud Run's request_count, aligned per minute by
  Cloud Monitoring, so volume cannot truncate the count.
- The background is the median of the 10 same-day minutes before the drain;
  the 24 h/48 h baselines are gone.
- Scheduled 503s come out: drain-return deferrals and sticky/placement answers
  to a host's own early retry (host-rate-limited, host-in-flight), each split
  across the minutes its 30 s sample covers.
- The rung budget counts only sustained breaches: two straight minutes over
  max(1.5x, +20) warn, over max(2x, +40) would-block.
- The report carries a paceVerdict over the three pace checks. seal_canary
  downloads the canary cell's report and seals that verdict; a batch below the
  default pace needs PASS, from a report on the same cell that drained at that
  pace.
- Docs: the step-down rule reads paceVerdict, 30 s waits for the lane service
  time (#25645), and the staging step is dropped since staging drains unpaced.

Replayed read-only: 10-01 c29 would-block (9 minutes over 41.5/min); all nine
10-02 cells and 10-01 c25 paceVerdict PASS.

* fix(relay): a partial count already past a block line blocks, in the shadow gate's Cloud SQL and pool checks

A truncated FATAL count is a floor, and one runtime sample over the SQL-failure
line is a fact, so neither waits for a complete read. The waiter-run rule still
needs a complete run, since holes can join two runs into one.

* fix(relay): a canary pace PASS needs a real cohort and whole telemetry; one median-based 503 check

From the final review of #25639:
- canaryPaceVerdict seals PASS only from a report that drained at least 400
  hosts (about half a 10-02 US cell), so a near-empty canary cannot authorize
  a fast batch.
- A director-metrics sub-window with fewer samples than one instance emits
  is unverified, so an empty or short Logging answer is never a calm drain.
- seal_canary names the shadow artifact, report path and cell from the gate's
  normalized cell list, as cell_1 uploads it.
- director503 folds into nonDrain503Budget as a single-minute spike rule,
  max(10x median, 200), dropping the pre-drain peak statistic. All 30 replayed
  windows keep their verdicts.

+### Drain pace ladder
+
+The `drain-pace-window-ms` input sets the window the cell spreads its drain sends over. Each
+drained host re-dials the director as soon as it reads `drain`, so the window sets the re-placement
+arrival rate: hosts / window, about 1.8-2.7 hosts/s for a US cell at the default. The window also
+sets two waits: restart-safe needs an empty runtime for (ceil(window / 5 s) + 1) consecutive
+5-second samples, and the drain step's overall timeout is the 15-minute migration lease plus the
+window (20 minutes at the default).
+
+- Allowed values are `300000` (the default, and every wave before this input), `60000`, and
+  `30000`. The wave validator refuses anything else, and each cell job checks again.
+- Below `300000` is for US general cells only (C7-C10, C13-C16, C19-C26, C32, C33). Asia drains
+  are bound by the target cells' own accept rate (about 4-6 hosts/s per Asia cell), not by the
+  window. Migration-only cells hold no hosts. Both stay at `300000`.
+- A non-default window must be named at the end of the confirmation, for example
+  `ROLL_RELAY_SAME_CAP <target-digest> <cells> drain-pace-window-ms=60000`. A confirmation that
+  names no window confirms `300000`, so a form left at another value fails closed.
+- A canary's authority records its window and its pace verdict (below). A batch may use that
+  window or a slower one, never a faster one. A batch below `300000` also needs the canary's pace
+  verdict to be PASS. Stepping back to `300000` mid-ladder needs no new canary.
+- A cell on an image without paced drains rejects the window, and the job falls back to an
+  unpaced drain. The job records what the cell accepted, and a canary that did not drain at its own
+  window seals `UNVERIFIED`.
+
+**What judges a paced drain.** The shadow health gate (report only, after each cell) judges two
+checks the pace can move. Together they are the report's `paceVerdict`, which the canary seals:
+
+- **Director 503s** come from Cloud Run's own request counter (`run.googleapis.com/request_count`,
+  code 503), aligned per minute by Cloud Monitoring. A log read of them stops at its entry limit
+  in exactly the minutes that matter: it read only 20k of 10-01 c29's ~31k.
+- **Scheduled 503s are taken out**, using the director's `orca_relay_runtime_metrics` counters:
+  - drain-return deferrals;
+  - sticky and placement answers to a host's own early retry (`host-rate-limited`,
+    `host-in-flight`).
+
+  Each tells one host when to come back. What is left is lanes, capacity, or the database
+  refusing work. On 10-02 the early-retry answers were about three quarters of all 503s, and
+  they doubled with placement volume whether or not a drain was running.
+- **The background** is the median minute of the 10 same-day minutes before the drain. A busy
+  morning raises it with the window, and one incident minute inside it does not.
+
+| check | rule |
+|---|---|
+| `nonDrain503Budget` | Two consecutive minutes above max(1.5x background, background + 20) warn; above max(2x, background + 40) would-block. One minute above max(10x, 200) would-block on its own; any other single minute is a transient |
+| `drainDeferrals` | Warn if the largest Retry-After exceeds 30 s; would-block above 60 s. Reports deferrals and re-placements |
+
+A read that fails, hits its limit, or returns fewer director-metric samples than one instance
+emits (one per 30 s) makes both checks `unverified`. An empty answer is not a calm director.
+
+Replayed read-only against past rolls:
+- Every brownout and herd replayed is `would-block`: 10-01 c29, 09-23 c27, 09-24 c30, both 10-01
+  c28 windows, and the 09-28 and 09-30 herds. Each peaked at 5,999 non-drain 503s a minute or
+  more. 10-01 c29, for example, ran 9 minutes in a row over a 41.5/min line.
+- Clean rolls: all nine 10-02 cells, 10-01 c25, and 11 other US and Asia rolls have a pace
+  verdict of PASS. Their largest minute was 87, and none held two minutes over the warn line.
+- Two daytime Asia c29 rolls on 10-01 read WARN and WOULD_BLOCK on sustained non-drain 503s at the
+  default pace. Their largest minute was 112, still under the 200 single-minute line.
+- These 30 verdicts are unchanged from before the per-minute peak check was folded into this
+  one.
+
+The other checks (`cellServing`, `cellPool`, `cloudSqlFatal`, `fleetPool:*`) stay in the overall
+verdict as context. They read the new boot and fleet-wide pools, so a clean roll at any pace can
+still WARN on them, and every 10-02 roll did on `cloudSqlFatal`.
+
+The report records:
+- `background`: the pre-drain minutes;
+- `nonDrain503Budget.perMinute`: the per-minute series;
+- `drain`: the window, the window the cell applied, the host count, and the seconds from
+  isolation to restart-safe.
+
+Two other 503 rules exist, and neither needs this split. The pre-drain sample's 500/min rule reads
+the 10 minutes *before* a drain, and a previous cell's drain has ended by then. The incident
+monitor already excludes 503s from its director 5xx rule.
+
+**Procedure.** One rung at a time, on routine US same-cap rolls:
+
+1. Before the first rung, run a fresh canary. This input is evidence code, so merging it
+   invalidates any sealed monitor or canary authority. Staging has no paced-drain path today: its
+   capacity proof drains unpaced. A rung's first use is therefore one production canary.
+2. Roll a `canary-apply` at the next rung. Use `60000` after a clean `300000` roll. Use `30000`
+   only after a clean `60000` roll, and only once the director reports the drain-return lane's
+   service time (`drainReturnServiceMs`, #25645). At 30 s the lane holds only if that time stays
+   under about 190 ms.
+3. A rung is clean when:
+   - the canary job succeeded;
+   - its `paceVerdict` is PASS, sealed only from a report on that cell that drained at least 400
+     hosts at that pace;
+   - time to empty is within window + hosts / 50 s + 10 s. Take `settledAfterSeconds` minus the
+     restart-safe quiet; this is an upper bound, since it includes the isolate.
+
+   The batch check enforces the PASS. A canary that sealed anything else authorizes only
+   `300000` batches. The 400-host floor exists because a pace is an arrival rate (hosts /
+   window). A canary that small would test less than half the rate a 692-782-host US cell
+   (10-02) reaches at the same window. Pick a canary cell above it.
+4. Record each rung, and keep the shadow gate JSON artifact with the row:
+
+   | Field | Source |
+   |---|---|
+   | Cell, hosts, window | The report's `drain` block |
+   | Measured drain rate | `drainDeferrals.replacementsPeakPerMinute`, and hosts / time to empty |
+   | Non-drain 503s | `nonDrain503Budget.perMinute` against `background.medianPerMinute` |
+   | Lane deferrals | `drainDeferrals.deferralsTotal` and `retryAfterSecondsMax` |
+   | Roll time | The cell job's duration |
+
+   This job does not report four of the rung's bars: drain-to-reconnected p95 (20 s), the
+   drain-return lane's service time, over-cap cells (0), and selector compare-and-swap retries
+   (at most 2). Read them by hand where a source exists, or record them as unmeasured until the
+   director observability work lands.
+5. If any bar fails, set the input back to `300000` for the rest of the wave and stop the ladder.
+   The `300000` batch needs no new canary.
+
 ### Pre-drain fleet-health sample
 
 A same-cap dispatch does not need a separate monitor run. Each `apply` wave samples fleet health

Subject: [PATCH 033/167] refactor(native-chat): keep the provider resume
 handle opaque to shared code (#24991)

* refactor(native-chat): keep the provider resume handle opaque to shared code

Shared structured-chat code parsed each provider's resume handle: Claude's
session id and branch leaf, Codex's thread id, through a 'claude' | 'codex'
union every new agent had to widen. The in-memory handle is now
{ transport, agent, nativeId, providerData? }: shared readers use nativeId,
lease and handle-chain checks compare transport and agent, and only the
Claude adapter reads its leaf (providerData).

Stored and wire forms are unchanged for Claude and Codex. One encoding
module writes their typed shapes and decodes both those and the neutral
shape a new transport uses, which an older build refuses as unreadable
rather than reading as Codex. Key and root strings, which fork seeds,
superseded creations and resume offers persist, stay byte-identical.

The journal's own handle type becomes the journal-row and attach-wire
encoding of the same handle, and the journal identity carries the
neutral handle (null before the provider proves one).

No user-visible change.

* fix(native-chat): derive journal-row provider handles from the journal identity

The journal row converter now takes the identity every caller already holds,
so a row's handle has one obvious constructor. Tests that wrote the in-memory
handle straight into journal rows now build it through that converter, and the
processless Claude fixture names a not-yet-proved handle as null.

* fix(native-chat): refuse a stored provider handle written in both forms

A typed Claude or Codex handle that also carries the neutral form's
transport, agent, native id or provider data named two identities; it
was read as Claude or Codex and the next write dropped the other one.
Such a row now stays unreadable and is set aside untouched.

* test(native-chat): use opaque handle in queued rejection fixture

* test(native-chat): share one Codex journal identity in the integration suite

Main grew the suite to the 800-line limit; the opaque-handle import pushed it
over. The two tests built the same identity inline.

* refactor(agent-session): name the handle's adapter state resumeCursor

Rename the neutral provider handle's providerData to resumeCursor before any
row persists the neutral form: it is an adapter-owned resume position (Claude's
transcript leaf), never identity. Claude/Codex stored and wire bytes are
unchanged; their typed shapes never carried the field.

State the stored-form contract (a handle's field set is closed; later per-link
data goes on the chain link, which every build preserves) and pin it with a
record round-trip test. Document that transport records the id space the
native id was minted in, which can differ from the agent's current transport.

- * A creation the provider never saved can be superseded by a new creation, which takes its place

+ * code reads only its transport, its agent, and the provider's own conversation id; anything else
+ * the provider needs to resume is `resumeCursor`, which only that provider's adapter reads. How a

Subject: [PATCH 034/167] test: check structured-chat code for Electron imports
 even before the runtime loads it (#24988)

* test: keep structured chat free of Electron imports

* test: widen runtime Electron ratchet to structured chat

* test: check whole structured-chat directories for Electron imports

Cover src/main/{native-chat,claude,codex}, src/shared and every structured-*
or agent-session-* file under src/main/runtime, so new files are checked by
default. A lane that exists today now fails loudly if it goes missing; only
the not-yet-landed acp/ and provider-process/ may be absent.

Move the test-only file rule into one classifier shared with the
localization audit, so -test-<thing> helpers and test doubles no longer
enter the production gate.

* test: run the Electron-import CLI path in tests and retire may-be-absent lanes

Export main() so the real-tree tests exercise the entry list CI uses,
check every required lane for the missing-directory error, and fail once
acp/ or provider-process/ exists while still allowed to be absent.

Subject: [PATCH 035/167] test(native-chat): cover paired runtime launch
 compatibility (#25072)

* test(native-chat): cover paired runtime launch compatibility

* test(native-chat): use production prompt response fingerprints

* test(native-chat): pass journal items to the paired-runtime outbox hook

Main made journalItems a required outbox input; mirror production by
passing the read state's items.

* test(native-chat): pin paired-runtime routing and capability questions

- Move the paired-runtime chat test into its own file and render the real
  session hook against a paired server that advertises today's capabilities
  while this machine advertises none, so Stop, prompt cancel, repeated Stop
  and question answers fail if their capability question goes to the wrong
  runtime. Add a local and a paired session sharing one id.
- Cross-version: state that the file pins the capability strings a
  v1.4.219 server really advertises, use the desktop's real handshake list,
  and keep the current server only as the control for the refusal.
- agent-launch-routing: give the released-server case a capable client so
  it is refused by the server gate, not the client one.

* test(native-chat): route the paired launch suite and cover the outline read

- Start the cross-version job when the launch route or the client list the
  desktop sends a paired host changes, since the paired launch suite runs
  them.
- Check the rail's conversation outline is read from the paired server, and
  narrow the hook test's header to what it covers.

Subject: [PATCH 036/167] Extract provider process supervision and stream
 reading from Codex (#24989)

* Move provider process supervision and stream reading out of Codex

* Preserve teardown behavior with checked mock types after move

* Apply provider launch environment and caller teardown labels

* Give provider child env one owner and gate Codex contract on the shared reader

resolveProviderChildEnv is now the only place that overlays and strips a
provider's environment; the spawn spec and the request-scoped Codex session
both call it. supervisedPosixLaunch only accepts a launch without env fields,
so an override can no longer be silently ignored there. Edits to the shared
stream reader or the env rule now run the real-binary Codex contract job.

Subject: [PATCH 037/167] feat(activity): multi-select agent rows with a bulk
 right-click menu (#25486)

Agent rows in the activity view now select like workspace cards (Cmd/Ctrl-click to toggle, Shift-click for a range), with a bulk right-click menu to mark agents read or unread and clear finished agents. Selection logic and the selected-row style are shared with the workspace list, and right-click menus close each other.

Subject: [PATCH 038/167] feat(relay): report lane service times, 503 causes,
 per-site hold p99 and a director-vs-cell lock-wait split (#25645)

* feat(relay): report lane service times, 503 causes, per-site hold p99 and lock-wait split

Adds the step-1 observability: drain-return and sticky slot service times,
every /v1/assign 503 by cause with a non-drain total, a p99 per lock hold
site (drain-return regional rows get their own site), a director-side
pg_stat_activity sample that splits lock waiters by director vs cell, and
a log line for each reserved_requests drift reconciliation corrects.
Log-based metrics for the new fields are declared in Terraform, not applied.

* fix(relay): classify a lock waiter by the first relay table its statement names

* fix(relay): attribute lock waiters to the root holder; document the director hold alert change

Every waiter after the first in a row-lock convoy is blocked by the first
waiter, so the sample now walks pg_blocking_pids to the root, reading it once
per waiter. The sampler is single-flight. Drain-return regional holds feeding
the non-paging director hold policy is documented as expected.

* docs(relay): note the lock-wait sample undercounts director waiters when the pool is full

+a lock it queues behind them and undercounts director waiters; a dedicated
+sampler connection would fix that. Summed waiters divided by `dbLockWaitSamplesDelta`
+is the mean number waiting, i.e. lock-wait seconds per second; directors and
+cells share one database user, so Query Insights cannot make this split.
+Reconciliation logs `orca_relay_reservation_drift` for each cell whose
+`reserved_requests` it corrected.

 `host-cooldown-ms` is the minimum gap between two rehomes of one host. It bounds the damage from
 a desktop whose region probe flips: without it the host would be dragged back across the ocean on
 every flip, since the preference age never expires while the host keeps reconnecting.

+Since the step-1 observability deploy, director holds also include the
+regional target rows a drain return locks (`cellInventoryHoldMaxSite:
+isolated-replacement`), so the director policy can fire during a roll's drain.
+That is expected and needs no action; `isolatedReplacementHoldMsP99` is the

Subject: [PATCH 039/167] fix(orchestration): give an OpenCode worker its task
 only once OpenCode can submit it (#25101)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* fix(orchestration): keep pressing Enter until an OpenCode worker's task starts

OpenCode 2 draws its input box before it has loaded its agent list from its
server, and silently drops an Enter that arrives in that gap. On a loaded
machine the gap outlasts the 0.5 s Orca waits after pasting, so a worker's
task sat unsent in the box while worker-start reported it ready.

OpenCode's turn start is now observed through its status hooks, like Codex
and Claude. While no turn has started, the prompt verifier presses Enter
again on an interval (per the agent row, opencode and opencode2) for as
long as the pane's hooks are reporting, never past an approval or question
prompt or a replaced pane, and at most a fixed number of times. A pane
whose hooks never report keeps today's single Enter and unobserved receipt.

* fix(opencode): give a worker its task only once OpenCode can submit it

OpenCode 2 draws its input box, and shows its cursor there, before its agent
list has loaded from its server, and it silently drops an Enter that arrives in
that gap. Orca pasted a worker's task on the box's cursor and pressed Enter half
a second later, so on a loaded machine the task stayed unsent in the box while
the worker read as started.

OpenCode's paste readiness now also waits for the row under the input box
(`<agent> · <model>`), which OpenCode paints only once the agent list exists.
The rule keys on the row's separator inside OpenCode's alternate screen, not on
names or colours. Both the opencode and opencode2 rows use it, worker start and
the renderer's draft paste alike. OpenCode 1 paints the row in the box's own
frame, so it is ready on the same read as before.

Recorded OpenCode 2.0.21 boots (cold, hidden pane, four at once, attached to a
running server) are the evidence; two more show an Enter after the row
submitting and one at the box being dropped. The earlier resubmit loop and the
settlement-provider changes are removed.

Co-Authored-By: Claude <noreply@anthropic.com>

* fix(opencode): prove the agent-row signal with natural captures and never paste a draft blind

Replaces three recordings made by launching four OpenCode boots at once with
natural single-run evidence: one cold start that pasted on the agent row and
pressed Enter on Orca's real 500 ms timing (submitted), and one cold start
recorded under heavy load from other sessions, where the paste on the box's
cursor and Orca's Enter came before the agent row and the brief stayed unsent.
Adds a 2.0.14 cold start as a cross-version check.

The renderer's draft paste no longer falls back to a blind paste when the
OpenCode agent-row signal never arrives: OpenCode would drop the Enter and
leave the draft in its box, so the caller gets its timeout notice instead.
Other agents keep the fallback.

* fix(opencode): type the single-signal predicate against the public signals

Co-Authored-By: Claude <noreply@anthropic.com>

* fix(opencode): read the agent row by its place on screen and wait for it only before Enter

- The agent-row signal now keys on structure: the `·` must sit on the line
  directly above the input box's bottom-left corner, so a `·` in the footer
  path or a session tab title no longer counts. Leaving the alternate screen or
  turning bracketed paste off withdraws what each part established.
- Only deliveries that press Enter wait for the row (new
  `submitPasteReadySignal`); drafts keep the box-cursor rule, as on main.
  Worker start always submits.
- When the box cursor has shown but the row never comes (OpenCode 2 drops the
  agent below 44 columns), both waiters proceed after a 5 s grace, as main
  did. A natural 40-column capture proves that start submits.
- The renderer's blind-paste fallback is back to main's behaviour.

Co-Authored-By: Claude <noreply@anthropic.com>

* fix(opencode): take the box at the readiness deadline while the agent-row grace is pending

- Both paste waiters resolve ready, not timed out, when the hard deadline
  lands while the 5 s grace is pending: the box was seen, so this is the
  verdict the box rule gave before.
- Tab-bound draft paste is tested to wait on the agent row only when Enter
  follows.
- Scanner: a separator pairs with its corner only inside one synchronized
  frame, row 0 clamps to 1, and the grace comment names the transparent-theme
  case. The draft signal type no longer admits the agent-row signal, whose
  grace only the paste waiters honour.

Co-Authored-By: Claude <noreply@anthropic.com>

* fix(opencode): withdraw the agent-row grace when OpenCode leaves the alternate screen

If OpenCode exited after drawing its box but before its agent row, the grace
still ran out and the task was pasted into the shell. Leaving the alternate
screen now clears the box cursor, and once an app has left it a cursor the
shell shows outside it no longer starts a grace. A terminal that never
forwards the alternate screen still gets one.

Co-Authored-By: Claude <noreply@anthropic.com>

* test(serialize): register the new OpenCode captures' pre-existing grid-restore counts

The six OpenCode 2 captures this PR adds hit the serializer limitations the
1.18.32 and 2.0.18 captures are already registered for: the live pen's
background (and once its bold bit) on restored cells, rows kept below the
source after a shrink, and the cursor one column short after a shrink. No
I1 or I3 failure; the serializer is unchanged.

Co-Authored-By: Claude <noreply@anthropic.com>

* fix(opencode): bound the readiness deadline's last settle check

With a grace pending, the deadline runs one more settle check, and over SSH
its foreground read could hold a past-due wait for the channel's 30 s
timeout. It now gives up after 2 s. Tests cover a hand-off, a failure and an
abort during that check, a refused grace settled at the deadline, the bound,
and the grace restarting at a hand-off.

Recorded with the timed Python PTY driver (each read stamped with ms since spawn; terminal queries answered like Orca's pane). One natural cold start, no other capture running; load average at start 59.44 / 56.29 / 68.90 from other work on the machine. --standalone, env -i with an isolated HOME and XDG dirs (no credentials; OpenCode Zen's free models), OPENCODE_DISABLE_AUTOUPDATE=1, OPENCODE_CONFIG_CONTENT {\"autoupdate\":false}, no ORCA_* vars; version and binary sha256 unchanged before and after. Why this run: below 44 columns OpenCode 2 leaves the agent, and so the ' \u00b7 ' separator, out of the row under its input box, which shows the model alone. The box cursor showed at 11338 ms; the one-line task was bracketed-pasted 5136 ms later, at the agent-row signal's grace, and Enter sent 592 ms after that (promptSentAtMs). OpenCode submitted it: the reply was painted. The only separators are in the reply's footer, never on the row above the box's bottom corner. <name>.timing.json holds each PTY read as [ms since spawn, UTF-16 length] and recordedUntilMs.",

NOT the timed Python driver: a node-pty probe script (each read kept with its ms since spawn; it answers no terminal queries) used while investigating this bug. Recorded at natural load: other sessions on the machine had the load average at 4.39 / 30.38 / 44.19 (read 11 minutes later; this capture ran alone). The user's own login and plugins in place, OPENCODE_DISABLE_AUTOUPDATE=1, no ORCA_* vars. Orca's worker-start timing was replayed: an 82-line brief was bracketed-pasted at the box's show-cursor (3157 ms) and Enter sent 502 ms later (3659 ms, promptSentAtMs). The agent/model row only painted at 4141 ms; OpenCode dropped the Enter and the brief stayed in the composer as [Pasted ~82 lines]; OpenCode painted nothing more from 4164 ms until the probe stopped it at 40 s (its exit frames are cut). Scrubbed with same-length placeholders: checkout path and ticket id, and two earlier session titles in the tab strip. <name>.timing.json holds each PTY read as [ms since spawn, UTF-16 length] and recordedUntilMs.",

Subject: [PATCH 041/167] feat(relay): one-command director deploy driver
 (#25642)

* feat(relay): add an operator-local driver for director deploys

One command runs the audited director deploy: preflight, pause rehome if
enabled, publish, deploy, optional cell configure, a digest-bound inspect,
the monitor dry-run, and re-enable. It only dispatches the existing
workflows, reads the published digest from the registry and the run log,
reads the monitor verdict from its sealed state, and enables with the
digests gcloud reports after the deploy. It stops at the first failure,
records state, and resumes from it.

* fix(relay): report and own the rehome pause; operator types every phrase

- Read the control back from pause and enable runs whatever their conclusion,
  and report PAUSED or UNCONFIRMED loudly.
- Resume re-enables only the pause this driver recorded (generation and run).
- Ctrl-C and SIGTERM print the same state and resume report.
- The operator types every workflow confirmation. A 5-minute soak gated on
  director 5xx runs before configure.
- A dry run keeps no state file. The quiet check pages through all runs.
  Run IDs come only from the printed URL. One step table drives execute,
  dry run and resume. The monitor verdict reuses verify-authority.

* fix(relay): read back only the driver's own rehome run; anchor the soak at the traffic switch

- The pause and enable read-back accepts only the control line its own step's mode prints, at the
  generation its own dispatch expected. A run adopted after a crash is settled even when green.
- The soak window opens a minute before the deploy run completed and is read a minute after it
  ends, for log ingestion lag.

* fix(relay): say what typing ENABLE_REGIONAL_REHOMING commits to

* fix(relay): the ENABLE prompt also names the 150 s evidence budget

* refactor(relay): derive every deploy decision from live state; no resume machinery

The driver keeps no state between runs. Each run reads the serving
director, its configured cells and the rehome control, and skips what is
already done.

- The only rehome fact it owns is the run that paused rehome. A re-run
  names it (--pause-run), and the driver checks it against that run's log
  and the live generation.
- A recover-enable line counts as the driver's own pause only with
  recovered: true. A director safety pause is never adopted (F3).
- Publish runs before the pause. A fresh run that finds rehome paused
  stops unless given --pause-run or --rehome-disabled (F2).
- Interrupts report a pause or enable still in flight as REHOME IS
  CHANGING (F1). PAUSE UNCONFIRMED and ENABLE UNCONFIRMED are distinct.
- A tripped soak is judged again on fresh traffic (F5). SIGHUP is
  handled, and a pending signal stops the driver before its next dispatch.
- Every stop prints the single command that finishes the deploy.

Removes the state file, --resume, step statuses, monitor adoption and
interrupted-dispatch adoption.

* fix(relay): never report done over an unexplained pause; prove pause ownership by actor

- G1: always read rehome; no early DONE.
- G2: --pause-run must be a rehome-control run by the same user.
- G3: a failed enable run is never an enable.
- C1: a pause or enable is reported as changing from the moment it is
  dispatched.
- C2: --leave-rehome-paused (was --rehome-disabled) refuses an enabled
  switch. Every printed command parses.
- G4: the enable-in-flight report prints both finishing commands.
- G5: the driver's own runs never block the quiet-lane check.

* test(relay): port the round-3 probes: hard kill mid-pause, unexplained disable after a failed enable

+### Director deploy driver
+
+`dev/scripts/drive-relay-director-deploy.mjs` runs a whole director deploy from an operator machine
+with `gh` and `gcloud` logged in. It only dispatches the workflows above and reads their results; it
+holds no credentials and changes no workflow. It never fills in a workflow's typed confirmation: the
+operator types each one when the driver reaches it.
+
+```bash
+cd cloud
+node dev/scripts/drive-relay-director-deploy.mjs --commit <reviewed main SHA> --dry-run
+node dev/scripts/drive-relay-director-deploy.mjs --commit <reviewed main SHA> \
+  [--configure production-gce-c34=sha256:<cell image digest>]
+```
+
+It keeps no state between runs. Every decision comes from live state read at the start of each run:
+
+- the serving director's digest and configured cells, from `gcloud`;
+- the admission selector, from an `Operate Relay Asia Admission` `inspect`;
+- the rehome control, from a rehome `inspect` at the generation the newest rehome run printed, or
+  at `--rehome-generation`.
+
+Steps already done are skipped: a serving digest that matches is not deployed again, and cells
+already configured are not configured again. It always reads rehome, even when nothing is left to
+do, so it never reports success over a pause it cannot explain.
+
+The sequence:
+
+1. **Preflight, read-only.** No `cloud-*` workflow is queued or running (all pages; the hourly
+   clock-skew monitor and `cloud-verify` excepted), and `main` is the reviewed commit.
+2. **Publish**, after the operator types `DEPLOY <commit prefix>`. It runs before rehome is touched,
+   so a moved `main` or a bad build needs no cleanup. The digest is the registry digest of
+   `relay:sha-<commit>`, and the run's own push line must name the same digest.
+3. **Pause**, only if rehome is enabled, after the operator types `PAUSE_REGIONAL_REHOMING`.
+4. **Deploy** with that digest, the paused generation, `preserve` for both regional inputs, no
+   prune, and the old serving digest as predecessor.
+5. **Soak**, with `--configure` only, while no wave is configured yet. It watches 5 minutes of
+   director 5xx and stops if they exceed twice the 5 minutes before the new revision existed, plus
+   25. The window starts at the traffic switch (a minute before the deploy run completed) when this
+   run deployed, otherwise at the time of the run, so a re-run judges fresh traffic. It is read a
+   minute late, to allow for log lag. Then the operator types `CONFIGURE_ASIA_DIRECTOR` and each
+   pending wave is configured.
+6. **Digest check.** A rehome `inspect` bound to the serving and rollback digests that `gcloud`
+   reports now. A wrong digest fails here, read-only, before 15 minutes of monitor evidence is
+   spent on it.
+7. **Monitor.** The operator types `ENABLE_REGIONAL_REHOMING`. The prompt says this arms an
+   automatic enable, sent about 17 minutes later, and only if the monitor is green and its evidence
+   is at most 150 s old. The monitor dry-run then starts. Its artifact passes the same
+   `relay-monitor-evidence.mjs verify-authority` check the enable job runs.
+8. **Enable** with the verified digests, within 150 s of the monitor completing.
+
+Steps 6 to 8 run only for a pause this driver owns.
+
+**Ownership.** The driver owns a pause only if it can name the run that made it, and the live
+control is still at that run's generation. Two kinds of line in a run's log prove it paused
+rehome:
+
+- `pause`;
+- `recover-enable` with `recovered: true`, meaning a failed enable that disabled rehome again itself.
+
+The run must be a rehome-control run by the same GitHub user. A `recover-enable` with
+`recovered: false` found rehome already disabled, for example by a director safety pause, and is
+never adopted. A failed enable run is never counted as an enable, whatever it printed last. A fresh run that finds rehome paused stops. It goes ahead only
+with:
+
+- `--pause-run <run>`, which an earlier run of this driver printed; or
+- `--leave-rehome-paused`, which deploys and leaves rehome paused. It refuses an enabled switch.
+
+A pause made by anything else is never lifted.
+
+**Stops.** On any failure, Ctrl-C, SIGTERM or SIGHUP, the driver prints what changed:
+
+- `REHOME IS CHANGING` when a pause or enable run is in flight and will apply on its own;
+- `PAUSE UNCONFIRMED` or `ENABLE UNCONFIRMED` when such a run printed no usable result;
+- `REHOME IS PAUSED by this driver` with the owning run;
+- the serving director, re-read;
+- the published digest;
+- the rollback point, with the `gh workflow run` command that redeploys it.
+
+It ends with the single command that finishes from where it stopped. That command carries
+`--publish-run` and `--pause-run`, and the driver re-verifies both against the runs' logs and live
+state. Each run writes a timestamped log under `~/.orca/relay-director-deploy/`
+(`--log-directory` overrides it).

Subject: [PATCH 043/167] feat(native-chat): publish where each submission was
 sent and the turn a stopped one was answered into (#25073)

* feat(native-chat): publish each submission's journal positions

A client never learned where in the journal a send was accepted or taken back,
so drawing a stopped send had to guess from its own row and from clocks, and the
guesses misfired after restarts. Each projected submission now carries
`submittedSequence` (its submission row) and `resolvedSequence` (the dispatch row
that resolved it; absent while pending): two optional fields, computed on every
fold from rows already stored, never stored themselves. Older clients ignore
them. The failure-fact schema moves to its own module to keep the journal schema
file within its size limit.

* test(native-chat): pin a submission's resolved position on the provider-echo accept path

Also say which rows can resolve a submission, and that the submission schema, not the shared type, omits acceptedSequence.

* refactor(native-chat): publish only where each submission was sent

A rejected send's own row now moves to its rejection (#24710), so the row that
resolved a send is the item's own position and needs no second copy. Keep
submittedSequence, the one journal-order record of where a send was sent.

* feat(native-chat): publish the turn a withdrawn Codex send was answered into

A send Codex answered into a turn that then ended without taking it is
rejected by that turn's end. The rejection row now names that turn's
record, and the submission carries it as answeredInTurnItemId, so a
client can tell which turn the send belonged to without guessing from
journal order or clocks. Absent on every other send.

* feat(native-chat): say how a withdrawn Codex send joined the turn it names

The answered turn becomes { turnItemId, via }: 'start' when Codex
answered the send's turn/start with that turn, 'steer' when Orca steered
it into that running turn. A client can then tell the turn's opener from
a send steered into it even when the opener is on an older page.

* feat(native-chat): state on every rejection whether it names a turn

A rejection a host writes now always carries answeredInTurn: the turn
Codex answered the send into, or null for none. A reader can then tell
'answered into no turn' from a row written before the field existed,
which keeps no answer and is placed by the older rules.

* refactor(native-chat): give the answered-turn schema its own module

Keeps the journal schema file within its line limit.

* docs(native-chat): say an unreadable answered turn reads as none

Subject: [PATCH 044/167] fix(terminal): submit startup commands with Enter on
 every platform (#23672)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* fix(terminal): submit startup commands with Enter on every platform

LF is Ctrl+J to a line editor, so a shell that remaps it left the command at the prompt.

Fixes #23250

Co-authored-by: Aashish Mahato <145881415+aashish254@users.noreply.github.com>

* test(terminal): expect CR in pty ipc startup tests

* fix(terminal): submit every line of a raw multiline startup command with CR

The CR switch only replaced the trailing terminator. On the raw path — a shell
with no bracketed paste, so each line break submits its own line — interior LFs
stayed LF, which is the same remappable Ctrl+J the fix set out to remove. A
multiline startup command in sh/dash/nushell/PowerShell therefore still stalled
partway through for a user who rebinds Ctrl+J. Normalise interior breaks to CR
on that path only; the bracketed-paste payload keeps its literal newlines.

* fix(terminal): quote multi-line PowerShell arguments on one line

A multi-line agent prompt was quoted as a single-quoted PowerShell string
with raw line breaks. Typed into Windows PowerShell 5.1 without PSReadLine,
each break submits a line and the shell waits at `>>` forever. Values with
CR/LF now become one double-quoted line with backtick escapes, keeping every
byte; single-line values keep the single-quoted form unchanged.

* style(terminal): keep typographic quotes as \u escapes in PowerShell quoting

Restores the escape form the single-quoted regex used on main and applies
it to the new double-quoted regex and the native argv test, so the diff
against main stays minimal and the characters are visible in review.

Subject: [PATCH 045/167] perf(tab-bar): scrolling the tab strip no longer
 re-renders every tab (#24240)

* perf(tab-bar): move scroll thumb position out of TabBar state

The thumb moved every scroll and resize frame, re-rendering every tab with it.

Fixes #24012

* perf(tab-bar): reuse the strip's resize observers for the scroll thumb

The thumb had its own observer on every tab, on top of the tab bar's.

* test(e2e): run the tab strip scroll spec without waiting on frames

CI's hidden window draws about one frame a second, so real wheel input timed out. Also drops Reflect.get for the anti-slop audit.

* test(tab-bar): pin that a re-render leaves the scroll thumb's geometry alone

The thumb's width and transform live outside React, so the element must survive a
hover re-render with its geometry intact.

* test(e2e): set the tab strip scroll start after the strip stops retitling

Opening the tabs leaves the strip pinned to its end, and the scroll event that
releases that pin only lands with the next frame - about a second in CI's hidden
window. A tab retitling inside that window re-pinned the strip to the end, so the
wheel sweep would start at an edge and every step would flip the edge flags.

Subject: [PATCH 046/167] fix(ai-vault): resume sessions whose worktree was
 deleted (#24236)

* fix(ai-vault): resume sessions whose worktree was deleted

SSH resumes typed `cd <deleted folder> &&`, so the agent never started, and
Codex preselected the deleted folder when resumed anywhere else.

Fixes #17745

Co-authored-by: kaluli123123 <295758798+kaluli123123@users.noreply.github.com>

* fix(ai-vault): keep folder-scoped SSH resumes in their recorded folder

Kimi resumed from another folder opens a new empty session under the same id.

* refactor(ai-vault): type the deleted-cwd drop with the resume session shape it feeds

Replaces the generic `T | Omit<T,'resumeCommand'>` return (and the
`Parameters<typeof ...>` leak it forced onto the launch hook) with the
exported session shape every resume builder already takes.

Adds the two uncovered branches: a live SSH folder keeps its scanner
command, and a local session is never probed at all.

Subject: [PATCH 047/167] fix(ssh): let a placed worktree seed while its host
 is in conflict (#23213)

One host tab on a folder this client lacks marked every worktree on the host unverifiable, so reopening an emptied one never got a terminal.

Fixes #22015

Subject: [PATCH 048/167] fix(sidebar): remember whether the left sidebar is
 open across restarts (#22682)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* Skip diff analysis after a result has been discarded (#24711)

Move the unchanged pure render-limit calculation after both existing generation and section-token rejection fences.

* Skip late browser grab toasts after their surface closes (#24727)

Reuse the existing mounted-owner ref at the toast presentation entry while preserving all admitted extraction/screenshot and clipboard completion.

* Classify native chat waiting messages once (#24771)

Use the existing native filter traversal to populate a fresh waiting array, keeping the original predicate, policy, projection and output ordering while classifying each actual private slot once.

* Skip discarded Kanban pruning for an empty selection (#24782)

Guard only the existing open pruning branch when both its private selected Set and nullable anchor are empty; retain all original pre-guard projections and nonempty/anchor-only/public-helper behavior.

* Index discovered test files once during shard selection validation (#24532)

Verified selection plans previously validated each selected filename with a scan of all discovered files. One per-call Set now handles membership checks. Exact source/discovery checks, nonempty selection, fallback to all tests, shard balancing and manifests remain intact.

* Clear the watchdog benchmark heartbeat when CPU sampling fails (#24802)

Move the existing initial CPU observation and histogram enable inside the existing try/finally so their failures clear the sampler's owned heartbeat, preserving successful operation order and original errors.

* Reuse the parsed notification when leasing a push delivery (#24645)

* Reuse the parsed notification when leasing a push delivery

Pass the notification already parsed for the dismissal check into the existing private delivery builder.

* Reuse the parsed notification when leasing a push delivery

Pass the notification already parsed for the dismissal check into the existing private delivery builder.

* Update README downloads badge

* Let retired-cache GC observations settle across the existing six-turn budget (#24967)

* Collect test-selection evidence when full unit tests fail (#24955)

* Collect advisory unit-selection evidence from failed full runs

* Trigger checks after retargeting the evidence fix to main

* Check each project repository once while filtering mobile cards (#24540)

Reuse exact raw source/slug matching decisions within one project filter call, preserving the matcher, membership, negative matches, output order and identity.

* Skip renderer callbacks after their request has ended (#24631)

Reuse the existing pending-request identity check before starting its deferred renderer callback.

* Decode single-piece saved-session tails without copying them (#24632)

Decode the existing owned Buffer directly when the EOF tail has one piece; preserve the existing concatenation for multiple pieces.

* Avoid irrelevant scroll-action searches in Mac snapshots (#24731)

Check the current pure action name before searching for vertical scroll actions in the same immutable array.

* Stop copying every retained browser page before attachment (#24553)

Find the first page/generation match directly in the existing insertion-ordered Map instead of copying all page references into an array.

* Reuse event byte sizes when relay watchers notify several clients (#24558)

Store the existing grouped numeric byte-size array on the already call-local watcher batch sizing object, for reuse by later chunking clients.

* Stop building unused import candidates in the test planner (#24611)

Replace the existing ordered extension map/find with a loop that forms each candidate only when its existing lookup is reached.

* docs(terminal): explain local macOS/Linux shell startup files

Document the actual login/interactive shell startup-file order and existing shell setup behavior.

* test(terminal): restore the live fish fixture prerequisites (#24947)

A restored pane waits for the initial status replay before subscribing to
PTY output. This fixture never settled that replay, so fish printed its
mode-2031 arm before the renderer connected. Its PTY API also omitted the
reset-input listener required by the serializer, aborting attachment.

Settle and dispose the existing startup-snapshot registration and provide
the same reset-listener mock used by the other PTY tests. The real fish
child-stdin assertions and timeouts remain unchanged. No production change.

* Use the measured pnpm lookup policy automatically in hosted root CI (#24951)

* Select lookup automatically for the measured hosted root-install profile

* Record hosted automatic-mode cold cache publication proof

* fix: bound remote generation setup and honor OpenCode option terminators

Count execution-host profile resolution inside the existing request deadline, cancel its waiter promptly, and pass only the remaining time to the child. Shared bounded profile probes keep their existing cache lifetime; the SSH transport margin is unchanged.

Read OpenCode output format from active final-argv options before -- so literal prompt arguments cannot select the JSON finalizer.

Fresh exact-source controls reproduce nine failures before; 139 related checks pass after, including primary/fallback delays, deadline boundaries, cancellation, parser metadata, and SSH lanes. Node typecheck and strict changed-file lint pass.

* Preserve scanner service cache assertions and refresh Antigravity opening metadata

* test(jcode): measure the gate against the synchronous path, not the clock

The absolute 1s bound was the flake CI shard 3/8 hit: it is tight enough to catch
a synchronous gate on an idle laptop and too tight on a loaded runner. Measuring
the same POST both ways on the same machine makes the claim a ratio, which is what
the test is actually about. Mutation-checked: a synchronous gate reads 6120ms
against a 1517ms observer.

* test(jcode): drop the wall-clock gate assertion

* fix(jcode): address CodeRabbit review on #22539

- Windows posted no payload at all: the shared builder reads `payload@-` from
  stdin, which the gate has already drained and observer hooks never receive, so
  every Windows event was dropped. Write the env var to a temp file and pipe it.
- The daemon pre-warm never fired for daemon-host spawns, which is the default
  local path; it now runs there too, and from the final env so the daemon gets the
  hook port and token.
- A failed runtime-dir mkdir took down every local terminal, jcode or not.
- removeJcodeManagedHooks matched the raw line, so a user hook whose comment
  mentioned the managed script was deleted; matching on Windows never worked.
- A managed entry left by a copied home or a platform switch is now repointed
  instead of being reported as user-owned forever.
- The OSC colour skip only checked launchAgent, so a command- or telemetry-named
  jcode pane still leaked the reply into its composer.
- `['hooks']` and a commented scalar are recognised, instead of appending a
  second [hooks] table that makes jcode reject the whole config.
- A failed tool's error is marked as tool output rather than agent prose.
- The vault keeps a session's stored name, counts its tokens, and skips
  background_task and [Scheduled task] turns.

* fix(jcode): read the journal once per turn, key prompts by byte offset

The jcode prompt reader ran a synchronous bounded file scan plus a JSON
parse on every hook event. jcode blocks on pre_tool, so a turn that ran
four tools charged the user eight scans of latency it did not need — the
prompt cannot change inside a turn.

- Cache the journal read per pane, refreshed on the turn boundary that
  can change it. The cache holds the whole evidence record, since
  hasExplicitUserPrompt needs the transcript-evidence flag and not just
  the text, and it joins the existing pane-scoped lifecycle (close,
  rename, reset) rather than living in a module singleton.
- Key a journal prompt by its absolute byte offset instead of its
  region-local line index. The backward scan windows the file from EOF,
  so appending shifted every boundary and reminted the key for a prompt
  that never moved; a repeated turn_end then slipped past the same-hash
  dedupe as a second done event with duplicate telemetry.
- Pin the platform in the daemon pre-warm tests. The pre-warm is a no-op
  off POSIX, so the dedupe and retry cases would have passed vacuously
  on a Windows runner.

* fix(jcode): quote the managed hook path, drop tools from patch prompts

Three fixes, all on paths this PR could not exercise locally.

The managed hook command was stored as a bare path. jcode tokenizes that
string shell-style before exec'ing it directly (parse_hook_command,
crates/jcode-terminal-launch/src/lib.rs): unquoted whitespace splits, and
every unquoted backslash is consumed as an escape. So on Windows
`C:\Users\me\.orca\agent-hooks\jcode-hook.cmd` reached exec as
`C:Usersme.orcaagent-hooksjcode-hook.cmd` and no hook fired at all, and a
POSIX home with a space split into two arguments. Store the path
single-quoted (verbatim, backslashes included), falling back to double
quotes for a path containing a single quote. Existing bare entries are
already repointed by the stale-key path, and getStatus accepts both forms
so the repair is not reported as a user-owned hook. The quoting helper was
previously dead code that only tests called; the three production sites
now use it. isJcodeManagedCommand also normalizes separators, since a
`/`-only needle never matched a Windows entry.

Commit-message generation feeds a staged patch to `jcode run` as the
prompt — attacker-influenced text — while jcode's default profile exposes
shell, read, write, and MCP. Pass `--tool-profile none`, which resolves to
an empty allowed-tool set in jcode's config (base_allowed_tools), matching
the read-only posture claude (plan) and codex (read-only) already take.

docs/reference/jcode-hook-events.md was never actually in this PR: the
repo ignores docs/** and tracks reference docs by allow-list only, so the
captured-payload evidence four source comments point at was silently
dropped. Allow-list it.

* test(jcode): pin the tool-profile flag in the generation plan too

Co-authored-by: czzczz <chanzrz_zbf@foxmail.com>

* fix(text-generation): refuse an oversized argv prompt on Linux too

The pre-spawn size guard only ran on Windows. Linux caps a single argv
entry at MAX_ARG_STRLEN (32 pages, 128 KiB on a 4-KiB-page host) and
execve fails with E2BIG past it, so an agent that delivers the whole
prompt as one argument — jcode, and the other argv-delivery agents —
failed on a large staged diff with an error the user could not act on.

The cap is per-argument and in bytes, which is why it is not the Windows
line budget: 40k chars trips Windows and is nowhere near the Linux limit,
so folding them together would have refused prompts Linux runs fine.

* fix(jcode): register in main's remote-installer guard, drop our duplicate

Rebasing onto 853 commits of main surfaced two things the earlier branch
had hidden.

main already owns a guard for the issue-#7253 bug class
(`remote-hook-service-registry-coverage.test.ts`). This branch had added a
second, near-identical one — a parallel implementation of a test that
already existed, which is what AGENTS.md's reuse rule is about. Deleted
ours and registered jcode in main's, which is the one that has kept pace
with every agent added since.

Also fixes a missing separator in the mobile icon map. `pnpm tc` does not
cover `mobile/`, so only the session-route closure suite caught it.

Co-authored-by: czzczz <chanzrz_zbf@foxmail.com>

* fix(jcode): decompose the four files jcode pushed over max-lines

Adding an agent tipped four modules past their line budget. AGENTS.md
forbids a `max-lines` disable or a per-file bump, so each is split on a
real seam rather than silenced:

- agent-catalog.tsx keeps `AgentIcon`, which 70+ files import, and the
  rows move out. The rows alone exceed the 300-line budget a `.ts` file
  gets, so they follow the primary/secondary split this repo already uses
  for commit-message agent specs.
- getAgentResumeArgv -> agent-resume-argv.ts, re-exported so the 18 call
  sites keep one import path.
- isDiscoverableSessionFile/pathSegments -> session-file-discovery.ts.
- remoteCodexSources -> remote-session-scanner-codex-sources.ts; Codex is
  the one remote agent with two CODEX_HOME roots.

Also:
- Records the readiness-census baseline jcode now needs. main added that
  gate while this branch was out; the fixture is the recorded 74-case
  matrix, not a hand-written one.
- Restores two entries a rebase resolution silently dropped from
  config/tsconfig.cli.json (gitlab/project-ref-parser,
  startup/shell-path-probe). Nothing to do with jcode; losing them was a
  conflict-resolution mistake on this branch.

* feat(native-chat): open structured chats on the paired Orca server that owns the workspace (#24205)

* fix(native-chat): a host admits structured sessions by client capability, not its own chat setting

A host's experimentalStructuredNativeChat decided whether any paired client could reach
agentSession.* at all, and whether session.tabs.* showed it structured tabs. That setting is the
host user's own launch preference: whether a new agent opens as a chat or a terminal is decided by
whoever launches it. Using it as admission control meant a client whose own preference was
"structured chat" was refused on a host whose preference was "terminal", and chats opened while
the setting was on were withheld from mobile once it was turned off.

The gate now asks one thing: did the client advertise agent-session.structured.v1 (in-process
callers negotiate nothing and are always admitted). Tab projection and restore follow the same
rule. With the setting no longer gating anything, the separate cleanup gate (close, cancel,
unsubscribe, release), which existed only so those kept working after the setting was switched
off, is identical to the main gate and is folded into it. The settings listener that republished
tabs when the setting changed is removed, since projection no longer depends on it.

The host setting still picks the default for launches that start on the host itself
(agent.launch from mobile, orchestration worker-start).

* fix(native-chat): the desktop declares structured chat support to paired hosts

The desktop renderer advertised agent-session.structured.v1 (and the Claude, turn-item and
background-task capabilities that go with it) to its own main process but not to a paired Orca
server. The server therefore refused every agentSession.* call from the desktop and stripped
structured chat tabs out of the tab list it published to it, so a structured chat running on a
paired server never appeared on the desktop, even though the renderer already mirrors a host's
agent-session tabs and drives each one against the server that owns its workspace.

The same renderer reads structured chats on either host, so the remote Electron list now carries
the same structured-session capabilities as the local one, and the capability test pins that
nothing is advertised only locally.

* feat(native-chat): open structured chats on the paired server that owns the workspace

With the structured-chat default on, an agent launched in a workspace that lives on a paired Orca
server always opened as a terminal (or the terminal-backed chat view). Three things kept it off
the structured path: the launch check refused every host but this machine, a remote workspace was
handed to the host-published terminal path before the structured route was even considered, and
the structured launch pipeline sent create and every follow-up call to this machine's runtime.

A workspace's owning runtime is fixed, so the pipeline now derives it from the workspace instead
of assuming this machine (structured-agent-session-owner.ts, the same derivation the chat pane
already uses to read a session). The launch intent carries that target; the pre-create support
check, create, the publication check and fence read, the launch prompt send, held option picks,
the "focus this chat" marker, the placeholder tab's host, and tab close/purge all use it.

The launch check now accepts a paired server and asks that server's own capabilities (read from
the status the client already cached for it) rather than this machine's. An SSH workspace stays
terminal-backed: no Orca runtime runs there. The host still answers createSupport before
anything is created, so an older server that refuses shows the failure in the chat tab.

A chat the user closed before its create landed is now also retired on the paired server when it
publishes, as the local sync already does. Orchestration workers placed on another runtime are
unchanged: federation creates terminal agents only.

* fix(native-chat): negotiate client-chosen launch mode so released phones and old servers keep terminals

Hosts advertise agent-session.structured.client-launch-mode.v1: they admit
structured sessions by client capability alone. A remote client that does
not advertise it (phones released before agent.launch) asks createSupport
to pick the launch mode, so the host keeps answering that with its own
setting, exactly as before. Cleanup methods keep their own named gate so a
future admission condition cannot make close or cancel refusable.

* refactor(runtime): keep the Electron client capability list in its own module

protocol-version.ts is at its line budget; the list is what the desktop
advertises to paired hosts, not the host's own contract.

* fix(native-chat): the desktop declares it picks each launch mode itself

Paired hosts and the desktop's own main process then answer createSupport
by the workspace rather than by their own chat setting.

* fix(native-chat): pin each structured chat to the host it was launched on

- Route: a paired server opens a chat only when it advertises the
  client-chosen launch mode; an older server keeps its terminal. Its
  capabilities come from the store's host status, not the compatibility
  cache that is empty after boot or reconnect.
- A launch command override is this machine's: the route applies it only
  locally, and a host's createSupport refuses on its own override.
- The owning host is resolved once, from the same value the route used,
  and carried on the launch intent, its persisted record (legacy records
  load as local), the provisional tab and every mirrored chat tab. Close,
  purge, retry and reload read it instead of re-deriving it from a
  worktree id two hosts can share; an owner that cannot be named refuses.
- Cancellation tombstones record their host: only that host's
  authoritative inventory retires one, restored cleanup closes it there,
  and a paired host's tombstone expires after 30 days if it never answers.
- A paired server's frame settles launches it published, as the local
  inventory already does for this machine.

* fix(native-chat): a paired server that declines a chat opens its terminal instead

createSupport only reads, so both of its non-answers are settled before
anything is created:
- A paired server that answers it cannot run the chat (a WSL repo, a
  Claude account mismatch, its own launch command override) closes the
  chat tab and opens the terminal the route would have chosen, with a
  notice saying why. This machine's own decline stays a failed chat.
- A host that could not be asked closes the chat tab and leaves one
  failure toast, instead of a lingering "could not confirm" chat.

* test(native-chat): a provisional chat carries its launch's host and hands pre-create failures on

* chore(native-chat): justify the two type assertions this change's lines touch

* test(native-chat): state why each staged test fixture is cast

* fix(native-chat): chats that already exist keep showing whatever the chat setting says

The structured chat setting decides only what new agents open as. With it
off, this machine's structured chats used to be hidden while the host,
which no longer reads the setting, still reported them to the workspace
activation gate, so a workspace holding only a chat opened empty. The
local chat mirror and its startup restore now run whatever the setting
says, the continue-after-restart offer follows the chats that exist, and
the setting's copy says it applies to new agents.

* fix(native-chat): the browser client keeps its host terminal on paired servers

A browser client whose own preferences turn structured chat on took the
structured route for every paired-server workspace, but its handshake
never says it reads structured sessions, so the server refused the chat
and the user got a failed chat tab where a host terminal used to open.
The route for a paired host now also asks what this client advertises to
it: the desktop's list does, the browser client's does not. Its handshake
list is now a named constant the route reads, so the two cannot drift.

The chat setting's copy now says it runs on paired Orca servers too;
WSL and SSH hosts still use terminal chat.

* fix(native-chat): a retried launch a paired server declines opens its terminal too

A launch restored after a reload settles only through its Retry, so a
declining paired server left a failed chat there while a first launch got
the server's terminal and a notice. The chat's Retry now hands the same
pre-create failures to the same replacement, carrying the prompt the
launch had staged.

* refactor(native-chat): a paired host's cancelled-chat record ends on its 30-day TTL

The paired census re-read a host's whole inventory after every
authoritative frame to retire tombstones, and a tombstone restored after
a reload needed a second such frame, so in practice it retired nothing.
A tombstone guards a random session id and is inert once stale; the chat
is already closed on its host whenever a frame shows it. The census, its
trigger in the mirror layer and its cleanup are removed; the owner-scoped
tombstones, close-on-sight, the TTL and publication marking from frames
stay.

* fix(native-chat): a chat's pane and status read from the host recorded on its tab

The chat pane and its sidebar status still derived the host from the
workspace id, which two hosts can share; a paired chat in a non-active
same-id workspace was read from this machine. Both now read the owner
stamped on the tab, as close, purge and publication already do.

* fix(native-chat): "Resume in chat" follows the terminal resume's host rule

Agent Session History offered "Resume in chat" for a conversation
recorded on this machine into a paired server's workspace, where its
transcript does not exist. A chat now resumes a conversation only on the
host that recorded it, as the terminal resume does, and that host is the
one asked whether it can resume history.

* fix(native-chat): the chat setting says older paired servers keep terminal chat

* test(native-chat): pin that a host advertises the client-chosen launch mode

* fix(native-chat): mirror this machine's chats only where it holds them

Round 1 ran the local chat mirror for everyone so existing chats show
whatever the setting says. That gave every desktop a permanent
session-tabs listener, which turns on the runtime's phone replication
paths, plus two full session-tab censuses at startup, and made the
browser client mirror its remote host a second time.

The runtime now says whether it holds structured chats: its structured
host is built only when saved chats were restored at startup or a client
created one here, and it announces the moment one is built. The mirror,
the startup restore and the continue-after-restart offer run only when
the setting launches chats or the host holds some, and never in the
browser client. A chat a paired client creates here with the setting off
still appears at once. The chat behaviour settings show wherever chats
exist, and the setting's copy says it picks what new agents open as. The
toggle-off teardown this made dead is removed.

* test(native-chat): route a paired-server launch over the capability lists both sides really advertise

* test(native-chat): record install listeners without a cast

* fix(native-chat): a paired server admits a chat before any of it exists here

The desktop opened a paired server's chat tab, launch record, queued
prompt and focus intent before asking the server, so a "no" needed a
replacement that undid and redid all of it, and every piece it missed
was a bug: the workspace deselected, the caller told "failed" while a
terminal ran its prompt, the caller's arguments and other queued prompts
lost, and a create whose reply was lost treated as never sent.

A paired launch now asks the server first and commits nothing until it
answers. Admitted opens the chat as before. Declined runs the caller's
own launch as the server's terminal, with the existing notice (a resume
fails instead, having no terminal equivalent). Unreachable opens nothing
and names the server in one toast. The new-tab launcher reports the
host's surface for paired workspaces, as it did before paired chats,
with the prompt delivery of whichever surface got the prompt. The
replacement and its error classes are gone, and the probe inside a
launch is back to its old meaning: a "no" is a failed chat with Retry,
and no answer leaves "Could not confirm" with Retry and the prompt kept,
here as on this machine.

* fix(native-chat): mirror this machine's chats only once it holds one, not once its host is built

Session history, resume preparation, terminal resume commands and replay-safe phone launches all
build the structured host for users who never had a chat, which turned on the chat mirror and the
structured-only settings rows until the next restart. The signal is now derived from the host's
records (or a records file still owed its import) and pushed when the first chat is restored or
created. A throwing listener no longer fails the install that fired it.

* fix(native-chat): a fork's reveal never seeds a terminal beside the surface the launcher opens

Forking into a paired-server workspace revealed it as if nothing would open there, so the reveal
created a blank host terminal beside the forked chat (and beside a forked agent terminal on main).
The launcher always opens the fork's surface itself, so the reveal now says so for every surface,
as the fix-checks launch already does.

* fix(native-chat): a declined direct launch keeps the caller's CLI args; an unreachable resume toasts once

When a paired server declines a "Fix checks" chat in a new workspace, the terminal that opens
instead now carries the recipe's saved CLI arguments, launch platform and launch source, as the
terminal route did. "Resume in chat" to a server that cannot be reached showed the admission's
"Could not reach" toast and the vault's generic one; the admission marks its failure notified and
the vault adds nothing.

* fix(native-chat): a declined background create opens its terminal without switching workspaces

Since #23974 a worktree create the user moved away from must not pull them onto the new
workspace. When a paired server declined that create's chat, the fallback terminal opened as a new
agent tab, whose host create selects the workspace. The create now opens its own agent terminal the
way main's background branch does: in place from the request's startup plan (so its CLI args carry),
without selecting the workspace. A create the user is still watching keeps the new-tab fallback.

* test(native-chat): name the launch's host in main's new outbox fence test

Main's new staging-failure test calls settleStructuredAgentLaunchPrompt without the target this PR
made required; it is a local launch, as in the sibling tests.

* fix(native-chat): a paired server's new chat shows no model until the server reports the one it started

A chat on a paired server starts with the server's saved model and options, but the picker showed
this desktop's saved selection (or the catalog default) until the server reported a model, and a
pick made in that window was remembered on the server under that guessed model. A paired launch
now carries no desktop seed, and until the server reports its model the picker names no model and
takes no picks. Local chats are unchanged.

* test(native-chat): seed the paired repo without a cast

The repo literal already satisfies Repo, so the changed-lines cast gate has nothing to excuse.

* feat(native-chat): createSupport reports the saved selection a new chat on this host starts with

A chat on a paired server starts with the server's saved model and options, which the desktop could
not read, so its picker showed a guess. createSupport's answer, which the desktop already waits for
before a paired launch, now also carries that seed as a new optional field (older clients ignore it).
Create and createSupport read it through one resolver so they cannot drift.

* fix(native-chat): a paired server's new chat shows the selection the server will start it with

The paired server now names its saved model and options in the admission answer the desktop
already waits for. That seed goes into the launch intent and its persisted record, so the picker
shows the server's model at once, stays pickable like a local chat, and remembers picks on the
server under that model; a reload shows the same. The locked picker remains only for a server too
old to name a seed.

Also moves host admission and launch-outcome tracking into their own modules: the latest main
merge left structured-agent-session-launch.ts over the max-lines limit.

* test(native-chat): expect the launch intent's new seed argument in exact-call assertions

* refactor(protocol): move the Electron remote client capability list into its own module

Merging main left protocol-version.ts one line over the max-lines limit on this branch. The list of
capabilities the desktop advertises to a paired host moves, unchanged, into
electron-remote-runtime-client-capabilities.ts, the module the next PR in the stack already uses
for it; importers point there.

* fix(native-chat): a paired chat with no saved server model is pickable; Retry shows the server's current seed

A server whose user never saved a chat model sends no seed, and the desktop showed a locked,
model-only picker for it, although that is the common case: no server that can admit a paired chat
predates the seed field. Such a chat now behaves like a local chat with no saved model: the CLI
default, pickable. The lock and its snapshot helper are gone.

Retry kept the first admission's seed while the create probe, which already runs on every attempt,
reported the server's current one and dropped it. The probe's seed now replaces a paired launch's
seed and the picker's, so a retried chat shows what its create will run.

* test(cross-version): stub the launch seed resolver createSupport now reads

* test(protocol): pin the desktop capability divergence against what a paired server receives

Every paired transport sends the shared remote base plus the Electron list, so the
divergence test now compares that union with the renderer's local list instead of
the declared Electron list. A capability added only to the shared base can no
longer slip past it. The two base-only capabilities it surfaced are recorded:
skills.install-result.v2 has no local caller; the authoritative-inventory label is
read by the local tabs sync but dropped by main, and is marked unsettled.

The turn-item and both background-task-stop capabilities were already sent through
the shared base, so the Electron list no longer repeats them. The wire set is
unchanged; this PR's real change on the wire is structured.v1, the Claude
structured capability and the client launch-mode capability.

* fix(native-chat): the desktop tells its own host it picks each launch mode, so retrying an existing chat works with the setting off

* docs(native-chat): name the real exit for the released-phone createSupport rule

* fix(native-chat): the route reads the capabilities a paired host actually receives

The renderer decided whether a paired host would admit a chat from the desktop's Electron list, but
every desktop transport sends that list plus the shared remote base. They agreed only because the
route's checks happened to sit in both. The route input is now built with the same
remoteRuntimeClientCapabilities the transports use (the browser client already sends its list as is),
and a test pins each against the real handshake.

* test(cross-version): a released client still gets the host-setting createSupport answer; a launch-mode client gets supported plus the seed

* test(native-chat): let main's child-records test resolve each chat's owner

Main's new test mocks worktree-runtime-owner with only the runtime environment id, but the status
projection in this PR also resolves each structured chat's owner from the worktree. The mock keeps
the module's real exports and overrides only what the test pins.

* fix(deps): take #24204's lockfile that the merge reverted

* test(native-chat): let the Codex child-approval e2e unit test resolve each chat's owner

Its worktree-runtime-owner mock exported only the runtime environment id, but this PR's status
projection also resolves each structured chat's owner from the worktree. The mock now keeps the
module's real exports and overrides only that id, as structured-child-records-switch does.

* test(native-chat): move the close-race launch cases into their own file

Merging main added launch tests on both sides and took structured-agent-session-launch.test.ts past
the 800-line limit. The three cases where a tab close races a launch move to
structured-agent-session-launch-close-race.test.ts, with the same setup the other split launch
suites copy.

* feat(cli): add --unread/--read to orca worktree set

Pass validated read/unread flags through the existing workspace metadata update.

* Use the measured pnpm lookup policy automatically in hosted root CI (#24951)

* Select lookup automatically for the measured hosted root-install profile

* Record hosted automatic-mode cold cache publication proof

* fix: bound remote generation setup and honor OpenCode option terminators

Count execution-host profile resolution inside the existing request deadline, cancel its waiter promptly, and pass only the remaining time to the child. Shared bounded profile probes keep their existing cache lifetime; the SSH transport margin is unchanged.

Read OpenCode output format from active final-argv options before -- so literal prompt arguments cannot select the JSON finalizer.

Fresh exact-source controls reproduce nine failures before; 139 related checks pass after, including primary/fallback delays, deadline boundaries, cancellation, parser metadata, and SSH lanes. Node typecheck and strict changed-file lint pass.

* refactor(jcode): fold three reverse-scan copies into one, reuse the shared hook POST

The jcode journal reader, the Claude transcript reader and the Command Code

hand-rolled curl for buildPosixAgentHookPostCommand, which also gains it the
raw-JSON transport and the --noproxy guard the bespoke copy was missing.

* test(jcode): measure the gate against the synchronous path, not the clock

The absolute 1s bound was the flake CI shard 3/8 hit: it is tight enough to catch
a synchronous gate on an idle laptop and too tight on a loaded runner. Measuring
the same POST both ways on the same machine makes the claim a ratio, which is what
the test is actually about. Mutation-checked: a synchronous gate reads 6120ms
against a 1517ms observer.

* test(jcode): drop the wall-clock gate assertion

The bound was machine-speed sensitive and flaked on CI shard 3/8 at 1525ms. The
structural assertions (detached gate branch, foreground observer branch) and the
no-hang stdin drain cover the same contract without a timer.

Co-authored-by: czzczz <chanzrz_zbf@foxmail.com>

* fix(jcode): address CodeRabbit review on #22539

- Windows posted no payload at all: the shared builder reads `payload@-` from
  stdin, which the gate has already drained and observer hooks never receive, so
  every Windows event was dropped. Write the env var to a temp file and pipe it.
- The daemon pre-warm never fired for daemon-host spawns, which is the default
  local path; it now runs there too, and from the final env so the daemon gets the
  hook port and token.
- A failed runtime-dir mkdir took down every local terminal, jcode or not.
- removeJcodeManagedHooks matched the raw line, so a user hook whose comment
  mentioned the managed script was deleted; matching on Windows never worked.
- A managed entry left by a copied home or a platform switch is now repointed
  instead of being reported as user-owned forever.
- The OSC colour skip only checked launchAgent, so a command- or telemetry-named
  jcode pane still leaked the reply into its composer.
- `['hooks']` and a commented scalar are recognised, instead of appending a
  second [hooks] table that makes jcode reject the whole config.
- A failed tool's error is marked as tool output rather than agent prose.
- The vault keeps a session's stored name, counts its tokens, and skips
  background_task and [Scheduled task] turns.

* fix(jcode): read the journal once per turn, key prompts by byte offset

The jcode prompt reader ran a synchronous bounded file scan plus a JSON
parse on every hook event. jcode blocks on pre_tool, so a turn that ran
four tools charged the user eight scans of latency it did not need — the
prompt cannot change inside a turn.

- Cache the journal read per pane, refreshed on the turn boundary that
  can change it. The cache holds the whole evidence record, since
  hasExplicitUserPrompt needs the transcript-evidence flag and not just
  the text, and it joins the existing pane-scoped lifecycle (close,
  rename, reset) rather than living in a module singleton.
- Key a journal prompt by its absolute byte offset instead of its
  region-local line index. The backward scan windows the file from EOF,
  so appending shifted every boundary and reminted the key for a prompt
  that never moved; a repeated turn_end then slipped past the same-hash
  dedupe as a second done event with duplicate telemetry.
- Pin the platform in the daemon pre-warm tests. The pre-warm is a no-op
  off POSIX, so the dedupe and retry cases would have passed vacuously
  on a Windows runner.

* fix(jcode): quote the managed hook path, drop tools from patch prompts

Three fixes, all on paths this PR could not exercise locally.

The managed hook command was stored as a bare path. jcode tokenizes that
string shell-style before exec'ing it directly (parse_hook_command,
crates/jcode-terminal-launch/src/lib.rs): unquoted whitespace splits, and
every unquoted backslash is consumed as an escape. So on Windows
`C:\Users\me\.orca\agent-hooks\jcode-hook.cmd` reached exec as
`C:Usersme.orcaagent-hooksjcode-hook.cmd` and no hook fired at all, and a
POSIX home with a space split into two arguments. Store the path
single-quoted (verbatim, backslashes included), falling back to double
quotes for a path containing a single quote. Existing bare entries are
already repointed by the stale-key path, and getStatus accepts both forms
so the repair is not reported as a user-owned hook. The quoting helper was
previously dead code that only tests called; the three production sites
now use it. isJcodeManagedCommand also normalizes separators, since a
`/`-only needle never matched a Windows entry.

Commit-message generation feeds a staged patch to `jcode run` as the
prompt — attacker-influenced text — while jcode's default profile exposes
shell, read, write, and MCP. Pass `--tool-profile none`, which resolves to
an empty allowed-tool set in jcode's config (base_allowed_tools), matching
the read-only posture claude (plan) and codex (read-only) already take.

docs/reference/jcode-hook-events.md was never actually in this PR: the
repo ignores docs/** and tracks reference docs by allow-list only, so the
captured-payload evidence four source comments point at was silently
dropped. Allow-list it.

* test(jcode): pin the tool-profile flag in the generation plan too

The argv assertion lives in two places; --tool-profile none only landed in
one, so the plan test still expected the unrestricted argv.

* fix(text-generation): refuse an oversized argv prompt on Linux too

The pre-spawn size guard only ran on Windows. Linux caps a single argv
entry at MAX_ARG_STRLEN (32 pages, 128 KiB on a 4-KiB-page host) and
execve fails with E2BIG past it, so an agent that delivers the whole
prompt as one argument — jcode, and the other argv-delivery agents —
failed on a large staged diff with an error the user could not act on.

The cap is per-argument and in bytes, which is why it is not the Windows
line budget: 40k chars trips Windows and is nowhere near the Linux limit,
so folding them together would have refused prompts Linux runs fine.

* fix(jcode): register in main's remote-installer guard, drop our duplicate

Rebasing onto 853 commits of main surfaced two things the earlier branch
had hidden.

main already owns a guard for the issue-#7253 bug class
(`remote-hook-service-registry-coverage.test.ts`). This branch had added a
second, near-identical one — a parallel implementation of a test that
already existed, which is what AGENTS.md's reuse rule is about. Deleted
ours and registered jcode in main's, which is the one that has kept pace
with every agent added since.

Also fixes a missing separator in the mobile icon map. `pnpm tc` does not
cover `mobile/`, so only the session-route closure suite caught it.

* fix(jcode): decompose the four files jcode pushed over max-lines

Adding an agent tipped four modules past their line budget. AGENTS.md
forbids a `max-lines` disable or a per-file bump, so each is split on a
real seam rather than silenced:

- agent-catalog.tsx keeps `AgentIcon`, which 70+ files import, and the
  rows move out. The rows alone exceed the 300-line budget a `.ts` file
  gets, so they follow the primary/secondary split this repo already uses
  for commit-message agent specs.
- getAgentResumeArgv -> agent-resume-argv.ts, re-exported so the 18 call
  sites keep one import path.
- isDiscoverableSessionFile/pathSegments -> session-file-discovery.ts.
- remoteCodexSources -> remote-session-scanner-codex-sources.ts; Codex is
  the one remote agent with two CODEX_HOME roots.

Also:
- Records the readiness-census baseline jcode now needs. main added that
  gate while this branch was out; the fixture is the recorded 74-case
  matrix, not a hand-written one.
- Restores two entries a rebase resolution silently dropped from
  config/tsconfig.cli.json (gitlab/project-ref-parser,
  startup/shell-path-probe). Nothing to do with jcode; losing them was a
  conflict-resolution mistake on this branch.

* feat(native-chat): open structured chats on the paired Orca server that owns the workspace (#24205)

* fix(native-chat): a host admits structured sessions by client capability, not its own chat setting

A host's experimentalStructuredNativeChat decided whether any paired client could reach
agentSession.* at all, and whether session.tabs.* showed it structured tabs. That setting is the
host user's own launch preference: whether a new agent opens as a chat or a terminal is decided by
whoever launches it. Using it as admission control meant a client whose own preference was
"structured chat" was refused on a host whose preference was "terminal", and chats opened while
the setting was on were withheld from mobile once it was turned off.

The gate now asks one thing: did the client advertise agent-session.structured.v1 (in-process
callers negotiate nothing and are always admitted). Tab projection and restore follow the same
rule. With the setting no longer gating anything, the separate cleanup gate (close, cancel,
unsubscribe, release), which existed only so those kept working after the setting was switched
off, is identical to the main gate and is folded into it. The settings listener that republished
tabs when the setting changed is removed, since projection no longer depends on it.

The host setting still picks the default for launches that start on the host itself
(agent.launch from mobile, orchestration worker-start).

* fix(native-chat): the desktop declares structured chat support to paired hosts

The desktop renderer advertised agent-session.structured.v1 (and the Claude, turn-item and
background-task capabilities that go with it) to its own main process but not to a paired Orca
server. The server therefore refused every agentSession.* call from the desktop and stripped
structured chat tabs out of the tab list it published to it, so a structured chat running on a
paired server never appeared on the desktop, even though the renderer already mirrors a host's
agent-session tabs and drives each one against the server that owns its workspace.

The same renderer reads structured chats on either host, so the remote Electron list now carries
the same structured-session capabilities as the local one, and the capability test pins that
nothing is advertised only locally.

* feat(native-chat): open structured chats on the paired server that owns the workspace

With the structured-chat default on, an agent launched in a workspace that lives on a paired Orca
server always opened as a terminal (or the terminal-backed chat view). Three things kept it off
the structured path: the launch check refused every host but this machine, a remote workspace was
handed to the host-published terminal path before the structured route was even considered, and
the structured launch pipeline sent create and every follow-up call to this machine's runtime.

A workspace's owning runtime is fixed, so the pipeline now derives it from the workspace instead
of assuming this machine (structured-agent-session-owner.ts, the same derivation the chat pane
already uses to read a session). The launch intent carries that target; the pre-create support
check, create, the publication check and fence read, the launch prompt send, held option picks,
the "focus this chat" marker, the placeholder tab's host, and tab close/purge all use it.

The launch check now accepts a paired server and asks that server's own capabilities (read from
the status the client already cached for it) rather than this machine's. An SSH workspace stays
terminal-backed: no Orca runtime runs there. The host still answers createSupport before
anything is created, so an older server that refuses shows the failure in the chat tab.

A chat the user closed before its create landed is now also retired on the paired server when it
publishes, as the local sync already does. Orchestration workers placed on another runtime are
unchanged: federation creates terminal agents only.

* fix(native-chat): negotiate client-chosen launch mode so released phones and old servers keep terminals

Hosts advertise agent-session.structured.client-launch-mode.v1: they admit
structured sessions by client capability alone. A remote client that does
not advertise it (phones released before agent.launch) asks createSupport
to pick the launch mode, so the host keeps answering that with its own
setting, exactly as before. Cleanup methods keep their own named gate so a
future admission condition cannot make close or cancel refusable.

* refactor(runtime): keep the Electron client capability list in its own module

protocol-version.ts is at its line budget; the list is what the desktop
advertises to paired hosts, not the host's own contract.

* fix(native-chat): the desktop declares it picks each launch mode itself

Paired hosts and the desktop's own main process then answer createSupport
by the workspace rather than by their own chat setting.

* fix(native-chat): pin each structured chat to the host it was launched on

- Route: a paired server opens a chat only when it advertises the
  client-chosen launch mode; an older server keeps its terminal. Its
  capabilities come from the store's host status, not the compatibility
  cache that is empty after boot or reconnect.
- A launch command override is this machine's: the route applies it only
  locally, and a host's createSupport refuses on its own override.
- The owning host is resolved once, from the same value the route used,
  and carried on the launch intent, its persisted record (legacy records
  load as local), the provisional tab and every mirrored chat tab. Close,
  purge, retry and reload read it instead of re-deriving it from a
  worktree id two hosts can share; an owner that cannot be named refuses.
- Cancellation tombstones record their host: only that host's
  authoritative inventory retires one, restored cleanup closes it there,
  and a paired host's tombstone expires after 30 days if it never answers.
- A paired server's frame settles launches it published, as the local
  inventory already does for this machine.

* fix(native-chat): a paired server that declines a chat opens its terminal instead

createSupport only reads, so both of its non-answers are settled before
anything is created:
- A paired server that answers it cannot run the chat (a WSL repo, a
  Claude account mismatch, its own launch command override) closes the
  chat tab and opens the terminal the route would have chosen, with a
  notice saying why. This machine's own decline stays a failed chat.
- A host that could not be asked closes the chat tab and leaves one
  failure toast, instead of a lingering "could not confirm" chat.

* test(native-chat): a provisional chat carries its launch's host and hands pre-create failures on

* chore(native-chat): justify the two type assertions this change's lines touch

* test(native-chat): state why each staged test fixture is cast

* fix(native-chat): chats that already exist keep showing whatever the chat setting says

The structured chat setting decides only what new agents open as. With it
off, this machine's structured chats used to be hidden while the host,
which no longer reads the setting, still reported them to the workspace
activation gate, so a workspace holding only a chat opened empty. The
local chat mirror and its startup restore now run whatever the setting
says, the continue-after-restart offer follows the chats that exist, and
the setting's copy says it applies to new agents.

* fix(native-chat): the browser client keeps its host terminal on paired servers

A browser client whose own preferences turn structured chat on took the
structured route for every paired-server workspace, but its handshake
never says it reads structured sessions, so the server refused the chat
and the user got a failed chat tab where a host terminal used to open.
The route for a paired host now also asks what this client advertises to
it: the desktop's list does, the browser client's does not. Its handshake
list is now a named constant the route reads, so the two cannot drift.

The chat setting's copy now says it runs on paired Orca servers too;
WSL and SSH hosts still use terminal chat.

* fix(native-chat): a retried launch a paired server declines opens its terminal too

A launch restored after a reload settles only through its Retry, so a
declining paired server left a failed chat there while a first launch got
the server's terminal and a notice. The chat's Retry now hands the same
pre-create failures to the same replacement, carrying the prompt the
launch had staged.

* refactor(native-chat): a paired host's cancelled-chat record ends on its 30-day TTL

The paired census re-read a host's whole inventory after every
authoritative frame to retire tombstones, and a tombstone restored after
a reload needed a second such frame, so in practice it retired nothing.
A tombstone guards a random session id and is inert once stale; the chat
is already closed on its host whenever a frame shows it. The census, its
trigger in the mirror layer and its cleanup are removed; the owner-scoped
tombstones, close-on-sight, the TTL and publication marking from frames
stay.

* fix(native-chat): a chat's pane and status read from the host recorded on its tab

The chat pane and its sidebar status still derived the host from the
workspace id, which two hosts can share; a paired chat in a non-active
same-id workspace was read from this machine. Both now read the owner
stamped on the tab, as close, purge and publication already do.

* fix(native-chat): "Resume in chat" follows the terminal resume's host rule

Agent Session History offered "Resume in chat" for a conversation
recorded on this machine into a paired server's workspace, where its
transcript does not exist. A chat now resumes a conversation only on the
host that recorded it, as the terminal resume does, and that host is the
one asked whether it can resume history.

* fix(native-chat): the chat setting says older paired servers keep terminal chat

* test(native-chat): pin that a host advertises the client-chosen launch mode

* fix(native-chat): mirror this machine's chats only where it holds them

Round 1 ran the local chat mirror for everyone so existing chats show
whatever the setting says. That gave every desktop a permanent
session-tabs listener, which turns on the runtime's phone replication
paths, plus two full session-tab censuses at startup, and made the
browser client mirror its remote host a second time.

The runtime now says whether it holds structured chats: its structured
host is built only when saved chats were restored at startup or a client
created one here, and it announces the moment one is built. The mirror,
the startup restore and the continue-after-restart offer run only when
the setting launches chats or the host holds some, and never in the
browser client. A chat a paired client creates here with the setting off
still appears at once. The chat behaviour settings show wherever chats
exist, and the setting's copy says it picks what new agents open as. The
toggle-off teardown this made dead is removed.

* test(native-chat): route a paired-server launch over the capability lists both sides really advertise

* test(native-chat): record install listeners without a cast

* fix(native-chat): a paired server admits a chat before any of it exists here

The desktop opened a paired server's chat tab, launch record, queued
prompt and focus intent before asking the server, so a "no" needed a
replacement that undid and redid all of it, and every piece it missed
was a bug: the workspace deselected, the caller told "failed" while a
terminal ran its prompt, the caller's arguments and other queued prompts
lost, and a create whose reply was lost treated as never sent.

A paired launch now asks the server first and commits nothing until it
answers. Admitted opens the chat as before. Declined runs the caller's
own launch as the server's terminal, with the existing notice (a resume
fails instead, having no terminal equivalent). Unreachable opens nothing
and names the server in one toast. The new-tab launcher reports the
host's surface for paired workspaces, as it did before paired chats,
with the prompt delivery of whichever surface got the prompt. The
replacement and its error classes are gone, and the probe inside a
launch is back to its old meaning: a "no" is a failed chat with Retry,
and no answer leaves "Could not confirm" with Retry and the prompt kept,
here as on this machine.

* fix(native-chat): mirror this machine's chats only once it holds one, not once its host is built

Session history, resume preparation, terminal resume commands and replay-safe phone launches all
build the structured host for users who never had a chat, which turned on the chat mirror and the
structured-only settings rows until the next restart. The signal is now derived from the host's
records (or a records file still owed its import) and pushed when the first chat is restored or
created. A throwing listener no longer fails the install that fired it.

* fix(native-chat): a fork's reveal never seeds a terminal beside the surface the launcher opens

Forking into a paired-server workspace revealed it as if nothing would open there, so the reveal
created a blank host terminal beside the forked chat (and beside a forked agent terminal on main).
The launcher always opens the fork's surface itself, so the reveal now says so for every surface,
as the fix-checks launch already does.

* fix(native-chat): a declined direct launch keeps the caller's CLI args; an unreachable resume toasts once

When a paired server declines a "Fix checks" chat in a new workspace, the terminal that opens
instead now carries the recipe's saved CLI arguments, launch platform and launch source, as the
terminal route did. "Resume in chat" to a server that cannot be reached showed the admission's
"Could not reach" toast and the vault's generic one; the admission marks its failure notified and
the vault adds nothing.

* fix(native-chat): a declined background create opens its terminal without switching workspaces

Since #23974 a worktree create the user moved away from must not pull them onto the new
workspace. When a paired server declined that create's chat, the fallback terminal opened as a new
agent tab, whose host create selects the workspace. The create now opens its own agent terminal the
way main's background branch does: in place from the request's startup plan (so its CLI args carry),
without selecting the workspace. A create the user is still watching keeps the new-tab fallback.

* test(native-chat): name the launch's host in main's new outbox fence test

Main's new staging-failure test calls settleStructuredAgentLaunchPrompt without the target this PR
made required; it is a local launch, as in the sibling tests.

* fix(native-chat): a paired server's new chat shows no model until the server reports the one it started

A chat on a paired server starts with the server's saved model and options, but the picker showed
this desktop's saved selection (or the catalog default) until the server reported a model, and a
pick made in that window was remembered on the server under that guessed model. A paired launch
now carries no desktop seed, and until the server reports its model the picker names no model and
takes no picks. Local chats are unchanged.

* test(native-chat): seed the paired repo without a cast

The repo literal already satisfies Repo, so the changed-lines cast gate has nothing to excuse.

* feat(native-chat): createSupport reports the saved selection a new chat on this host starts with

A chat on a paired server starts with the server's saved model and options, which the desktop could
not read, so its picker showed a guess. createSupport's answer, which the desktop already waits for
before a paired launch, now also carries that seed as a new optional field (older clients ignore it).
Create and createSupport read it through one resolver so they cannot drift.

* fix(native-chat): a paired server's new chat shows the selection the server will start it with

The paired server now names its saved model and options in the admission answer the desktop
already waits for. That seed goes into the launch intent and its persisted record, so the picker
shows the server's model at once, stays pickable like a local chat, and remembers picks on the
server under that model; a reload shows the same. The locked picker remains only for a server too
old to name a seed.

Also moves host admission and launch-outcome tracking into their own modules: the latest main
merge left structured-agent-session-launch.ts over the max-lines limit.

* test(native-chat): expect the launch intent's new seed argument in exact-call assertions

* refactor(protocol): move the Electron remote client capability list into its own module

Merging main left protocol-version.ts one line over the max-lines limit on this branch. The list of
capabilities the desktop advertises to a paired host moves, unchanged, into
electron-remote-runtime-client-capabilities.ts, the module the next PR in the stack already uses
for it; importers point there.

* fix(native-chat): a paired chat with no saved server model is pickable; Retry shows the server's current seed

A server whose user never saved a chat model sends no seed, and the desktop showed a locked,
model-only picker for it, although that is the common case: no server that can admit a paired chat
predates the seed field. Such a chat now behaves like a local chat with no saved model: the CLI
default, pickable. The lock and its snapshot helper are gone.

Retry kept the first admission's seed while the create probe, which already runs on every attempt,
reported the server's current one and dropped it. The probe's seed now replaces a paired launch's
seed and the picker's, so a retried chat shows what its create will run.

* test(cross-version): stub the launch seed resolver createSupport now reads

* test(protocol): pin the desktop capability divergence against what a paired server receives

Every paired transport sends the shared remote base plus the Electron list, so the
divergence test now compares that union with the renderer's local list instead of
the declared Electron list. A capability added only to the shared base can no
longer slip past it. The two base-only capabilities it surfaced are recorded:
skills.install-result.v2 has no local caller; the authoritative-inventory label is
read by the local tabs sync but dropped by main, and is marked unsettled.

The turn-item and both background-task-stop capabilities were already sent through
the shared base, so the Electron list no longer repeats them. The wire set is
unchanged; this PR's real change on the wire is structured.v1, the Claude
structured capability and the client launch-mode capability.

* fix(native-chat): the desktop tells its own host it picks each launch mode, so retrying an existing chat works with the setting off

* docs(native-chat): name the real exit for the released-phone createSupport rule

* fix(native-chat): the route reads the capabilities a paired host actually receives

The renderer decided whether a paired host would admit a chat from the desktop's Electron list, but
every desktop transport sends that list plus the shared remote base. They agreed only because the
route's checks happened to sit in both. The route input is now built with the same
remoteRuntimeClientCapabilities the transports use (the browser client already sends its list as is),
and a test pins each against the real handshake.

* test(cross-version): a released client still gets the host-setting createSupport answer; a launch-mode client gets supported plus the seed

* test(native-chat): let main's child-records test resolve each chat's owner

Main's new test mocks worktree-runtime-owner with only the runtime environment id, but the status
projection in this PR also resolves each structured chat's owner from the worktree. The mock keeps
the module's real exports and overrides only what the test pins.

* fix(deps): take #24204's lockfile that the merge reverted

* test(native-chat): let the Codex child-approval e2e unit test resolve each chat's owner

Its worktree-runtime-owner mock exported only the runtime environment id, but this PR's status
projection also resolves each structured chat's owner from the worktree. The mock now keeps the
module's real exports and overrides only that id, as structured-child-records-switch does.

* test(native-chat): move the close-race launch cases into their own file

Merging main added launch tests on both sides and took structured-agent-session-launch.test.ts past
the 800-line limit. The three cases where a tab close races a launch move to
structured-agent-session-launch-close-race.test.ts, with the same setup the other split launch
suites copy.

* feat(cli): add --unread/--read to orca worktree set

Pass validated read/unread flags through the existing workspace metadata update.

* test(terminal): restore the live fish fixture prerequisites (#24947)

A restored pane waits for the initial status replay before subscribing to
PTY output. This fixture never settled that replay, so fish printed its
mode-2031 arm before the renderer connected. Its PTY API also omitted the
reset-input listener required by the serializer, aborting attachment.

Settle and dispose the existing startup-snapshot registration and provide
the same reset-listener mock used by the other PTY tests. The real fish
child-stdin assertions and timeouts remain unchanged. No production change.

* fix: bound remote generation setup and honor OpenCode option terminators

Count execution-host profile resolution inside the existing request deadline, cancel its waiter promptly, and pass only the remaining time to the child. Shared bounded profile probes keep their existing cache lifetime; the SSH transport margin is unchanged.

Read OpenCode output format from active final-argv options before -- so literal prompt arguments cannot select the JSON finalizer.

Fresh exact-source controls reproduce nine failures before; 139 related checks pass after, including primary/fallback delays, deadline boundaries, cancellation, parser metadata, and SSH lanes. Node typecheck and strict changed-file lint pass.

* test(jcode): measure the gate against the synchronous path, not the clock

The absolute 1s bound was the flake CI shard 3/8 hit: it is tight enough to catch
a synchronous gate on an idle laptop and too tight on a loaded runner. Measuring
the same POST both ways on the same machine makes the claim a ratio, which is what
the test is actually about. Mutation-checked: a synchronous gate reads 6120ms
against a 1517ms observer.

* test(jcode): drop the wall-clock gate assertion

The bound was machine-speed sensitive and flaked on CI shard 3/8 at 1525ms. The
structural assertions (detached gate branch, foreground observer branch) and the
no-hang stdin drain cover the same contract without a timer.

* fix(jcode): address CodeRabbit review on #22539

- Windows posted no payload at all: the shared builder reads `payload@-` from
  stdin, which the gate has already drained and observer hooks never receive, so
  every Windows event was dropped. Write the env var to a temp file and pipe it.
- The daemon pre-warm never fired for daemon-host spawns, which is the default
  local path; it now runs there too, and from the final env so the daemon gets the
  hook port and token.
- A failed runtime-dir mkdir took down every local terminal, jcode or not.
- removeJcodeManagedHooks matched the raw line, so a user hook whose comment
  mentioned the managed script was deleted; matching on Windows never worked.
- A managed entry left by a copied home or a platform switch is now repointed
  instead of being reported as user-owned forever.
- The OSC colour skip only checked launchAgent, so a command- or telemetry-named
  jcode pane still leaked the reply into its composer.
- `['hooks']` and a commented scalar are recognised, instead of appending a
  second [hooks] table that makes jcode reject the whole config.
- A failed tool's error is marked as tool output rather than agent prose.
- The vault keeps a session's stored name, counts its tokens, and skips
  background_task and [Scheduled task] turns.

* fix(jcode): read the journal once per turn, key prompts by byte offset

The jcode prompt reader ran a synchronous bounded file scan plus a JSON
parse on every hook event. jcode blocks on pre_tool, so a turn that ran
four tools charged the user eight scans of latency it did not need — the
prompt cannot change inside a turn.

- Cache the journal read per pane, refreshed on the turn boundary that
  can change it. The cache holds the whole evidence record, since
  hasExplicitUserPrompt needs the transcript-evidence flag and not just
  the text, and it joins the existing pane-scoped lifecycle (close,
  rename, reset) rather than living in a module singleton.
- Key a journal prompt by its absolute byte offset instead of its
  region-local line index. The backward scan windows the file from EOF,
  so appending shifted every boundary and reminted the key for a prompt
  that never moved; a repeated turn_end then slipped past the same-hash
  dedupe as a second done event with duplicate telemetry.
- Pin the platform in the daemon pre-warm tests. The pre-warm is a no-op
  off POSIX, so the dedupe and retry cases would have passed vacuously
  on a Windows runner.

* fix(jcode): quote the managed hook path, drop tools from patch prompts

Three fixes, all on paths this PR could not exercise locally.

The managed hook command was stored as a bare path. jcode tokenizes that
string shell-style before exec'ing it directly (parse_hook_command,
crates/jcode-terminal-launch/src/lib.rs): unquoted whitespace splits, and
every unquoted backslash is consumed as an escape. So on Windows
`C:\Users\me\.orca\agent-hooks\jcode-hook.cmd` reached exec as
`C:Usersme.orcaagent-hooksjcode-hook.cmd` and no hook fired at all, and a
POSIX home with a space split into two arguments. Store the path
single-quoted (verbatim, backslashes included), falling back to double
quotes for a path containing a single quote. Existing bare entries are
already repointed by the stale-key path, and getStatus accepts both forms
so the repair is not reported as a user-owned hook. The quoting helper was
previously dead code that only tests called; the three production sites
now use it. isJcodeManagedCommand also normalizes separators, since a
`/`-only needle never matched a Windows entry.

Commit-message generation feeds a staged patch to `jcode run` as the
prompt — attacker-influenced text — while jcode's default profile exposes
shell, read, write, and MCP. Pass `--tool-profile none`, which resolves to
an empty allowed-tool set in jcode's config (base_allowed_tools), matching
the read-only posture claude (plan) and codex (read-only) already take.

docs/reference/jcode-hook-events.md was never actually in this PR: the
repo ignores docs/** and tracks reference docs by allow-list only, so the
captured-payload evidence four source comments point at was silently
dropped. Allow-list it.

* test(jcode): pin the tool-profile flag in the generation plan too

The argv assertion lives in two places; --tool-profile none only landed in
one, so the plan test still expected the unrestricted argv.

Co-authored-by: czzczz <chanzrz_zbf@foxmail.com>

* fix(text-generation): refuse an oversized argv prompt on Linux too

The pre-spawn size guard only ran on Windows. Linux caps a single argv
entry at MAX_ARG_STRLEN (32 pages, 128 KiB on a 4-KiB-page host) and
execve fails with E2BIG past it, so an agent that delivers the whole
prompt as one argument — jcode, and the other argv-delivery agents —
failed on a large staged diff with an error the user could not act on.

The cap is per-argument and in bytes, which is why it is not the Windows
line budget: 40k chars trips Windows and is nowhere near the Linux limit,
so folding them together would have refused prompts Linux runs fine.

* fix(jcode): register in main's remote-installer guard, drop our duplicate

Rebasing onto 853 commits of main surfaced two things the earlier branch
had hidden.

main already owns a guard for the issue-#7253 bug class
(`remote-hook-service-registry-coverage.test.ts`). This branch had added a
second, near-identical one — a parallel implementation of a test that
already existed, which is what AGENTS.md's reuse rule is about. Deleted
ours and registered jcode in main's, which is the one that has kept pace
with every agent added since.

Also fixes a missing separator in the mobile icon map. `pnpm tc` does not
cover `mobile/`, so only the session-route closure suite caught it.

* fix(jcode): decompose the four files jcode pushed over max-lines

Adding an agent tipped four modules past their line budget. AGENTS.md
forbids a `max-lines` disable or a per-file bump, so each is split on a
real seam rather than silenced:

- agent-catalog.tsx keeps `AgentIcon`, which 70+ files import, and the
  rows move out. The rows alone exceed the 300-line budget a `.ts` file
  gets, so they follow the primary/secondary split this repo already uses
  for commit-message agent specs.
- getAgentResumeArgv -> agent-resume-argv.ts, re-exported so the 18 call
  sites keep one import path.
- isDiscoverableSessionFile/pathSegments -> session-file-discovery.ts.
- remoteCodexSources -> remote-session-scanner-codex-sources.ts; Codex is
  the one remote agent with two CODEX_HOME roots.

Also:
- Records the readiness-census baseline jcode now needs. main added that
  gate while this branch was out; the fixture is the recorded 74-case
  matrix, not a hand-written one.
- Restores two entries a rebase resolution silently dropped from
  config/tsconfig.cli.json (gitlab/project-ref-parser,
  startup/shell-path-probe). Nothing to do with jcode; losing them was a
  conflict-resolution mistake on this branch.

* feat(native-chat): open structured chats on the paired Orca server that owns the workspace (#24205)

* fix(native-chat): a host admits structured sessions by client capability, not its own chat setting

A host's experimentalStructuredNativeChat decided whether any paired client could reach
agentSession.* at all, and whether session.tabs.* showed it structured tabs. That setting is the
host user's own launch preference: whether a new agent opens as a chat or a terminal is decided by
whoever launches it. Using it as admission control meant a client whose own preference was
"structured chat" was refused on a host whose preference was "terminal", and chats opened while
the setting was on were withheld from mobile once it was turned off.

The gate now asks one thing: did the client advertise agent-session.structured.v1 (in-process
callers negotiate nothing and are always admitted). Tab projection and restore follow the same
rule. With the setting no longer gating anything, the separate cleanup gate (close, cancel,
unsubscribe, release), which existed only so those kept working after the setting was switched
off, is identical to the main gate and is folded into it. The settings listener that republished
tabs when the setting changed is removed, since projection no longer depends on it.

The host setting still picks the default for launches that start on the host itself
(agent.launch from mobile, orchestration worker-start).

* fix(native-chat): the desktop declares structured chat support to paired hosts

The desktop renderer advertised agent-session.structured.v1 (and the Claude, turn-item and
background-task capabilities that go with it) to its own main process but not to a paired Orca
server. The server therefore refused every agentSession.* call from the desktop and stripped
structured chat tabs out of the tab list it published to it, so a structured chat running on a
paired server never appeared on the desktop, even though the renderer already mirrors a host's
agent-session tabs and drives each one against the server that owns its workspace.

The same renderer reads structured chats on either host, so the remote Electron list now carries
the same structured-session capabilities as the local one, and the capability test pins that
nothing is advertised only locally.

* feat(native-chat): open structured chats on the paired server that owns the workspace

With the structured-chat default on, an agent launched in a workspace that lives on a paired Orca
server always opened as a terminal (or the terminal-backed chat view). Three things kept it off
the structured path: the launch check refused every host but this machine, a remote workspace was
handed to the host-published terminal path before the structured route was even considered, and
the structured launch pipeline sent create and every follow-up call to this machine's runtime.

A workspace's owning runtime is fixed, so the pipeline now derives it from the workspace instead
of assuming this machine (structured-agent-session-owner.ts, the same derivation the chat pane
already uses to read a session). The launch intent carries that target; the pre-create support
check, create, the publication check and fence read, the launch prompt send, held option picks,
the "focus this chat" marker, the placeholder tab's host, and tab close/purge all use it.

The launch check now accepts a paired server and asks that server's own capabilities (read from
the status the client already cached for it) rather than this machine's. An SSH workspace stays
terminal-backed: no Orca runtime runs there. The host still answers createSupport before
anything is created, so an older server that refuses shows the failure in the chat tab.

A chat the user closed before its create landed is now also retired on the paired server when it
publishes, as the local sync already does. Orchestration workers placed on another runtime are
unchanged: federation creates terminal agents only.

* fix(native-chat): negotiate client-chosen launch mode so released phones and old servers keep terminals

Hosts advertise agent-session.structured.client-launch-mode.v1: they admit
structured sessions by client capability alone. A remote client that does
not advertise it (phones released before agent.launch) asks createSupport
to pick the launch mode, so the host keeps answering that with its own
setting, exactly as before. Cleanup methods keep their own named gate so a
future admission condition cannot make close or cancel refusable.

* refactor(runtime): keep the Electron client capability list in its own module

protocol-version.ts is at its line budget; the list is what the desktop
advertises to paired hosts, not the host's own contract.

* fix(native-chat): the desktop declares it picks each launch mode itself

Paired hosts and the desktop's own main process then answer createSupport
by the workspace rather than by their own chat setting.

* fix(native-chat): pin each structured chat to the host it was launched on

- Route: a paired server opens a chat only when it advertises the
  client-chosen launch mode; an older server keeps its terminal. Its
  capabilities come from the store's host status, not the compatibility
  cache that is empty after boot or reconnect.
- A launch command override is this machine's: the route applies it only
  locally, and a host's createSupport refuses on its own override.
- The owning host is resolved once, from the same value the route used,
  and carried on the launch intent, its persisted record (legacy records
  load as local), the provisional tab and every mirrored chat tab. Close,
  purge, retry and reload read it instead of re-deriving it from a
  worktree id two hosts can share; an owner that cannot be named refuses.
- Cancellation tombstones record their host: only that host's
  authoritative inventory retires one, restored cleanup closes it there,
  and a paired host's tombstone expires after 30 days if it never answers.
- A paired server's frame settles launches it published, as the local
  inventory already does for this machine.

* fix(native-chat): a paired server that declines a chat opens its terminal instead

createSupport only reads, so both of its non-answers are settled before
anything is created:
- A paired server that answers it cannot run the chat (a WSL repo, a
  Claude account mismatch, its own launch command override) closes the
  chat tab and opens the terminal the route would have chosen, with a
  notice saying why. This machine's own decline stays a failed chat.
- A host that could not be asked closes the chat tab and leaves one
  failure toast, instead of a lingering "could not confirm" chat.

* test(native-chat): a provisional chat carries its launch's host and hands pre-create failures on

* chore(native-chat): justify the two type assertions this change's lines touch

* test(native-chat): state why each staged test fixture is cast

* fix(native-chat): chats that already exist keep showing whatever the chat setting says

The structured chat setting decides only what new agents open as. With it
off, this machine's structured chats used to be hidden while the host,
which no longer reads the setting, still reported them to the workspace
activation gate, so a workspace holding only a chat opened empty. The
local chat mirror and its startup restore now run whatever the setting
says, the continue-after-restart offer follows the chats that exist, and
the setting's copy says it applies to new agents.

* fix(native-chat): the browser client keeps its host terminal on paired servers

A browser client whose own preferences turn structured chat on took the
structured route for every paired-server workspace, but its handshake
never says it reads structured sessions, so the server refused the chat
and the user got a failed chat tab where a host terminal used to open.
The route for a paired host now also asks what this client advertises to
it: the desktop's list does, the browser client's does not. Its handshake
list is now a named constant the route reads, so the two cannot drift.

The chat setting's copy now says it runs on paired Orca servers too;
WSL and SSH hosts still use terminal chat.

* fix(native-chat): a retried launch a paired server declines opens its terminal too

A launch restored after a reload settles only through its Retry, so a
declining paired server left a failed chat there while a first launch got
the server's terminal and a notice. The chat's Retry now hands the same
pre-create failures to the same replacement, carrying the prompt the
launch had staged.

* refactor(native-chat): a paired host's cancelled-chat record ends on its 30-day TTL

The paired census re-read a host's whole inventory after every
authoritative frame to retire tombstones, and a tombstone restored after
a reload needed a second such frame, so in practice it retired nothing.
A tombstone guards a random session id and is inert once stale; the chat
is already closed on its host whenever a frame shows it. The census, its
trigger in the mirror layer and its cleanup are removed; the owner-scoped
tombstones, close-on-sight, the TTL and publication marking from frames
stay.

* fix(native-chat): a chat's pane and status read from the host recorded on its tab

The chat pane and its sidebar status still derived the host from the
workspace id, which two hosts can share; a paired chat in a non-active
same-id workspace was read from this machine. Both now read the owner
stamped on the tab, as close, purge and publication already do.

* fix(native-chat): "Resume in chat" follows the terminal resume's host rule

Agent Session History offered "Resume in chat" for a conversation
recorded on this machine into a paired server's workspace, where its
transcript does not exist. A chat now resumes a conversation only on the
host that recorded it, as the terminal resume does, and that host is the
one asked whether it can resume history.

* fix(native-chat): the chat setting says older paired servers keep terminal chat

* test(native-chat): pin that a host advertises the client-chosen launch mode

* fix(native-chat): mirror this machine's chats only where it holds them

Round 1 ran the local chat mirror for everyone so existing chats show
whatever the setting says. That gave every desktop a permanent
session-tabs listener, which turns on the runtime's phone replication
paths, plus two full session-tab censuses at startup, and made the
browser client mirror its remote host a second time.

The runtime now says whether it holds structured chats: its structured
host is built only when saved chats were restored at startup or a client
created one here, and it announces the moment one is built. The mirror,
the startup restore and the continue-after-restart offer run only when
the setting launches chats or the host holds some, and never in the
browser client. A chat a paired client creates here with the setting off
still appears at once. The chat behaviour settings show wherever chats
exist, and the setting's copy says it picks what new agents open as. The
toggle-off teardown this made dead is removed.

* test(native-chat): route a paired-server launch over the capability lists both sides really advertise

* test(native-chat): record install listeners without a cast

* fix(native-chat): a paired server admits a chat before any of it exists here

The desktop opened a paired server's chat tab, launch record, queued
prompt and focus intent before asking the server, so a "no" needed a
replacement that undid and redid all of it, and every piece it missed
was a bug: the workspace deselected, the caller told "failed" while a
terminal ran its prompt, the caller's arguments and other queued prompts
lost, and a create whose reply was lost treated as never sent.

A paired launch now asks the server first and commits nothing until it
answers. Admitted opens the chat as before. Declined runs the caller's
own launch as the server's terminal, with the existing notice (a resume
fails instead, having no terminal equivalent). Unreachable opens nothing
and names the server in one toast. The new-tab launcher reports the
host's surface for paired workspaces, as it did before paired chats,
with the prompt delivery of whichever surface got the prompt. The
replacement and its error classes are gone, and the probe inside a
launch is back to its old meaning: a "no" is a failed chat with Retry,
and no answer leaves "Could not confirm" with Retry and the prompt kept,
here as on this machine.

* fix(native-chat): mirror this machine's chats only once it holds one, not once its host is built

Session history, resume preparation, terminal resume commands and replay-safe phone launches all
build the structured host for users who never had a chat, which turned on the chat mirror and the
structured-only settings rows until the next restart. The signal is now derived from the host's
records (or a records file still owed its import) and pushed when the first chat is restored or
created. A throwing listener no longer fails the install that fired it.

* fix(native-chat): a fork's reveal never seeds a terminal beside the surface the launcher opens

Forking into a paired-server workspace revealed it as if nothing would open there, so the reveal
created a blank host terminal beside the forked chat (and beside a forked agent terminal on main).
The launcher always opens the fork's surface itself, so the reveal now says so for every surface,
as the fix-checks launch already does.

* fix(native-chat): a declined direct launch keeps the caller's CLI args; an unreachable resume toasts once

When a paired server declines a "Fix checks" chat in a new workspace, the terminal that opens
instead now carries the recipe's saved CLI arguments, launch platform and launch source, as the
terminal route did. "Resume in chat" to a server that cannot be reached showed the admission's
"Could not reach" toast and the vault's generic one; the admission marks its failure notified and
the vault adds nothing.

* fix(native-chat): a declined background create opens its terminal without switching workspaces

Since #23974 a worktree create the user moved away from must not pull them onto the new
workspace. When a paired server declined that create's chat, the fallback terminal opened as a new
agent tab, whose host create selects the workspace. The create now opens its own agent terminal the
way main's background branch does: in place from the request's startup plan (so its CLI args carry),
without selecting the workspace. A create the user is still watching keeps the new-tab fallback.

* test(native-chat): name the launch's host in main's new outbox fence test

Main's new staging-failure test calls settleStructuredAgentLaunchPrompt without the target this PR
made required; it is a local launch, as in the sibling tests.

* fix(native-chat): a paired server's new chat shows no model until the server reports the one it started

A chat on a paired server starts with the server's saved model and options, but the picker showed
this desktop's saved selection (or the catalog default) until the server reported a model, and a
pick made in that window was remembered on the server under that guessed model. A paired launch
now carries no desktop seed, and until the server reports its model the picker names no model and
takes no picks. Local chats are unchanged.

* test(native-chat): seed the paired repo without a cast

The repo literal already satisfies Repo, so the changed-lines cast gate has nothing to excuse.

* feat(native-chat): createSupport reports the saved selection a new chat on this host starts with

A chat on a paired server starts with the server's saved model and options, which the desktop could
not read, so its picker showed a guess. createSupport's answer, which the desktop already waits for
before a paired launch, now also carries that seed as a new optional field (older clients ignore it).
Create and createSupport read it through one resolver so they cannot drift.

* fix(native-chat): a paired server's new chat shows the selection the server will start it with

The paired server now names its saved model and options in the admission answer the desktop
already waits for. That seed goes into the launch intent and its persisted record, so the picker
shows the server's model at once, stays pickable like a local chat, and remembers picks on the
server under that model; a reload shows the same. The locked picker remains only for a server too
old to name a seed.

Also moves host admission and launch-outcome tracking into their own modules: the latest main
merge left structured-agent-session-launch.ts over the max-lines limit.

* test(native-chat): expect the launch intent's new seed argument in exact-call assertions

* refactor(protocol): move the Electron remote client capability list into its own module

Merging main left protocol-version.ts one line over the max-lines limit on this branch. The list of
capabilities the desktop advertises to a paired host moves, unchanged, into
electron-remote-runtime-client-capabilities.ts, the module the next PR in the stack already uses
for it; importers point there.

* fix(native-chat): a paired chat with no saved server model is pickable; Retry shows the server's current seed

A server whose user never saved a chat model sends no seed, and the desktop showed a locked,
model-only picker for it, although that is the common case: no server that can admit a paired chat
predates the seed field. Such a chat now behaves like a local chat with no saved model: the CLI
default, pickable. The lock and its snapshot helper are gone.

Retry kept the first admission's seed while the create probe, which already runs on every attempt,
reported the server's current one and dropped it. The probe's seed now replaces a paired launch's
seed and the picker's, so a retried chat shows what its create will run.

* test(cross-version): stub the launch seed resolver createSupport now reads

* test(protocol): pin the desktop capability divergence against what a paired server receives

Every paired transport sends the shared remote base plus the Electron list, so the
divergence test now compares that union with the renderer's local list instead of
the declared Electron list. A capability added only to the shared base can no
longer slip past it. The two base-only capabilities it surfaced are recorded:
skills.install-result.v2 has no local caller; the authoritative-inventory label is
read by the local tabs sync but dropped by main, and is marked unsettled.

The turn-item and both background-task-stop capabilities were already sent through
the shared base, so the Electron list no longer repeats them. The wire set is
unchanged; this PR's real change on the wire is structured.v1, the Claude
structured capability and the client launch-mode capability.

* fix(native-chat): the desktop tells its own host it picks each launch mode, so retrying an existing chat works with the setting off

* docs(native-chat): name the real exit for the released-phone createSupport rule

* fix(native-chat): the route reads the capabilities a paired host actually receives

The renderer decided whether a paired host would admit a chat from the desktop's Electron list, but
every desktop transport sends that list plus the shared remote base. They agreed only because the
route's checks happened to sit in both. The route input is now built with the same
remoteRuntimeClientCapabilities the transports use (the browser client already sends its list as is),
and a test pins each against the real handshake.

* fix(source-control): default Codex to GPT-5.6 Terra low (#24495)

* fix(source-control): use Codex's configured model by default

Source Control AI pinned Codex to gpt-5.5, which Codex retires on
2026-10-14. Any path that still resolves to that slug would then break
commit-message and PR-field generation.

Follow the Antigravity precedent (#21606): add a "Config default" entry
for Codex, make it the default, and omit --model when it is selected so
`codex exec` uses the model from the user's Codex config or Codex's own
default. Explicit model choices still pass --model.

Older remote servers would still build `--model default`, so advertise
git.codex-configured-model.v1 and have clients refuse the sentinel for
servers without it, the same way Antigravity is gated. The gate now
covers both agents, and the two capabilities live in their own module
because protocol-version.ts is at the max-lines limit.

Written with AI assistance (Claude Code).

Fixes #24481

* fix(source-control): honor -m, repo overrides and low effort for Codex

Review on #24495 found three gaps in the configured-model change.
The remote compatibility gate only recognized --model, so a recipe
passing Codex's -m short flag was rejected on older servers. The gate
also ignored the repository's per-operation model override that the
server applies. And moving Codex to Config default dropped the low
reasoning effort the pinned model used, which would change cost and
latency for users whose Codex config sets a higher effort.

* fix(source-control): match gate repo and model checks to the server

Repo ids can repeat across hosts, so the configured-model gate now reads
the repo row for the worktree's host instead of the first id match, the
same row the server applies. A recipe passing --model default or
-m default no longer counts as an explicit model, since an older server
still forwards that sentinel to the Codex CLI.

* fix(source-control): read only the worktree host's repo row in the gate

A worktree that names its own host must not fall back to the runtime
host's repo row, since the server applies the row for the worktree's
host. Also cover an environment id that needs URL encoding.

* fix(jira): search plain text when task search input isn't JQL (#22900)

* fix(jira): search plain text when task search input isn't JQL

The Tasks page sent every keystroke to Jira as JQL, so partial input like `s` failed with a 400.

Fixes #22265

* fix(jira): keep the JQL rejection reason behind Details

For plain-text searches the reason ("Field 'login' does not exist") reads as noise.

* fix(jira): announce the text-match notice to screen readers

* fix(jira): skip the wildcard when the last search word has punctuation

Jira doesn't split a wildcard term into words, so `login,*` or `c#*` matched nothing.

* fix(jira): keep the text-match live region mounted between searches

* fix(jira): keep hyphenated words like sign-in as plain text search

* fix(jira): retry a key-shaped search as text when no issue matches

Input like `utf-8`, `sha-256` or `covid-19` matches the issue-key shape, so
the search ran only `key = "UTF-8"` and showed an empty list with nothing to
explain why. An empty exact-key lookup is a wrong guess, not an answer, so
retry it as a text search — the same let-Jira-decide-then-fall-back rule the
JQL path already uses.

Splits the key and text builders apart so the caller can tell which branch it
took; `buildJiraTextSearchJql` keeps its combined behaviour for the
smart-workspace caller.

* fix(jira): let Jira's answer settle key, JQL and text guesses

Bare `in`/`is` sent everyday phrases down the JQL path, a key lookup Jira
answered with 400 never reached the text search, and a missing key like
PROJ-1401 was read as a lost connection. One key-or-text search now serves
the Tasks page and new-workspace, and one parser reads the status prefix.

* fix(jira): require IN to be its own word before a function name

`input (raw)` and `init()` read as `in` + a function call and took the JQL path.

* fix(runtime): report an open agent question as blocked to tui-idle waits (#24533)

OpenCode's question tool (and Pi/OMP ask tools and custom modals) put the
hook row in a waiting state but paint no dialog wording the blocked-text
layer knows, so the hook lane read the wait as pending and the tui-idle
wait timed out with no blocked reason. For agents whose hooks are
authoritative, a wait the hook reports with no recognised dialog text now
blocks with the existing agent-interactive-prompt reason, unless input
reached the pane after the row (it may have answered the question before
the next hook arrived).

* fix(runtime): read Codex's 'Implement this plan?' menu as blocked (#24536)

After a Plan-mode turn Codex shows a menu that owns the keyboard, but its Stop
hook has already fired, so a tui-idle wait settled ready and sent text into the
menu. A Codex blocked text anchor now names it an interactive prompt while its
key row ends the tail, written against a new 0.160.0 capture that is replayed
by the readiness census.

* feat: live updates for agent state rules (#24387)

Orca downloads a newer agent-state-rules.json from a fixed GitHub release (stable or next channel), validates it like the bundled rules, and applies it without a restart; a local override wins over the download, which wins over the bundled rules. A hand-started workflow from main is the only publisher; merging publishes nothing.

* fix(runtime): settle Codex tui-idle waits on its hook done, leaving working rows to the rules (#24541)

A headless orca serve has no window to write the Codex ready title, so a
Codex tui-idle wait settled only after three quiet seconds. Rule files gain
profile.hooks: "turn-end": a fresh hook done settles the wait, while a
working or permission row leaves the decision to the rules, so a Codex
whose Esc posts no event (before its Interrupt hook) cannot hang the wait.
Codex moves from identity-only to turn-end.

* fix(release): accept the build identity as a later declarator in the minified telemetry check (#24219)

* fix(windows): link the CLI launcher's C runtime statically so orca.exe runs without the VC++ Redistributable (#24484)

* feat(terminal): point an old terminal's Codex shared-server banner at a new terminal (STA-9051) (#24501)

* feat(terminal): point an old terminal's shared-server banner at a new terminal

A terminal opened before the update that added Orca's codex wrapper is
still served by an older terminal daemon, so a typed codex there joins
Codex's shared server. The banner now says why and offers a new terminal
instead of the global Fix, which changes Codex settings and stops a
server other sessions use.

Detection reads the owning daemon's protocol from the router's in-memory
session map, only after a pane is already found on the shared server.

Refs #24217, STA-9051

* refactor(terminal): simplify the old-terminal banner after review

- Open new terminal now works from Activity, which shows panes from
  worktrees that are not active: it activates the tab's worktree first.
- Inline the legacy-daemon check in the IPC handler over the existing
  getLegacyDaemonAdapters instead of a new routing export.
- One banner frame with the variant chosen inline; the Fix dialog is a
  sibling rather than a children slot.
- Rename CodexSharedServerJoin to CodexSharedServerStatus.

* fix(terminal): open the new terminal in the pane's own workspace, and only promise it where it helps

Open new terminal now always goes through the folder-aware workspace activation
(returning early when that fails) and reveals the floating panel for floating
panes, so folder workspaces and panes viewed from Activity open in the right place.

The old-terminal variant now shows only when the shell Codex was typed into gets
Orca's codex function from this build: zsh, bash and PowerShell from protocol 37,
fish from 39, cmd.exe never. The shell is the parent of the Codex process in the
process table the shared-server check already reads.

* feat(terminal): explain an old terminal's shared server in Learn more

Old-tab banner says Orca now gives each Codex its own server, and gains a
Learn more dialog: why it matters, why this terminal still shares, Open new
terminal, and a quieter way into the existing Turn off / Stop server steps.

* fix(terminal): shorten the old-terminal Learn more copy to one line

* fix(terminal): drop the global fix from the old-terminal dialog

A new terminal already runs Codex on its own server there, so turning off sharing everywhere only changes settings outside Orca and can end other sessions.

* fix(terminal): treat fish without config as a shell Orca does not wrap

* fix(terminal): return focus when a Codex shared-server dialog closes

Both banner dialogs are controlled with no Radix trigger, so Esc or X left
focus on document.body. Capture the active surface when the banner opens a
dialog and restore it on close via useModalReturnFocus; Open new terminal
skips the restore so the new terminal keeps focus.

* fix(filesystem): deleting a workspace no longer fails as 'outside allowed directories' in WSL-runtime C:\ projects (#24242)

* fix(filesystem): list a WSL-runtime repo's worktrees through its distro when authorizing paths

* fix(filesystem): record the Git that listed each repo's roots and keep WSL roots under repair

- Registration now takes the distro the caller listed through (create and catalog scan pass theirs)
  instead of re-resolving the runtime, so a stale-routed listing is relisted on the next miss.
- A runtime awaiting repair no longer counts as a routing change, so its last WSL listing stays
  authorized instead of being replaced by a host-Git listing.
- The routing check runs after each awaited refresh, so a runtime switch during an in-flight
  rebuild is corrected in the same request.
- Reuse the shared distro helper for listing; move the drift check into the relist policy and
  refresh the root set once per batch.

* test(worktrees): fail the host-Git scan registration test when nothing registers

* fix: dismiss Codex account prompt and return focus to terminal (#24683)

* chore(worktree): include create timing and spare outcome in the workspace create events (#24483)

* chore(worktree): include create timing and spare outcome in the workspace-created event

The workspace_created and workspace_create_failed events gain optional,
numbers-and-enums-only fields built from what the create already measured:
total and per-phase durations, the prepared-checkout hit/miss and miss
reason, the execution host (local/WSL/SSH), a worktree count bucket, how
many other creates were in flight, whether the repo has a post-checkout
hook (file existence only, probed after the create returns), and for a
failure the phase it died in plus elapsed time. No new git process runs;
consent and opt-out are unchanged.

* fix(worktree): attribute failed_phase by error, label WSL-path repos, skip the hook check with telemetry off

- failed_phase now names the outermost timed step the thrown error (or its cause) left, so a
  caught failure or a concurrent sibling step can no longer be misattributed; the old-relay SSH
  error keeps its cause so it still reads as git_worktree_add.
- execution_host follows the same rule Git routing uses, so a \\wsl.localhost repo reads wsl.
- The post-checkout hook check does not read the repo when telemetry is disabled.
- Privacy page mentions the miss reason code and the failed step.

* test(worktree): pin the old-relay SSH add error to git_worktree_add through its cause

* fix(worktree): name the create event field sets for their role, and type the old-relay test's caught error

* fix(worktree): send create events from runtime creates and record what the spare checkout did

Runtime creates (CLI, agents, phone app, paired clients, orchestration, server
automations) reuse prepared checkouts like the app's own creates, but recorded
no timing and sent no events. Both entry points now start one shared sender
(workspace-create-telemetry.ts), so every create sends exactly one event with
the same fields, plus create_entry_point (app | runtime).

Spare-checkout fields:
- concurrent_preparations: peak prepared-checkout builds and background
  discards running during the create, excluding the one it used; the window
  closes before the create's own re-arm starts.
- prepared_checkout_claim / prepared_checkout_discard phases, so on a miss
  git_worktree_add minus the prepared_checkout_* phases is the plain checkout.
- prepared_checkout_reset (none | base_moved | retargeted) replaces the
  retargeted flag; prepared_checkout_origin (prefetch | rearm) on hits.
- workspace_create_failed carries the spare outcome and its wait.
- repo_index_size_bucket from one stat of .git/index in the existing
  post-create probe (telemetry on, local/WSL only, 2 s cap).

* fix(worktree): add spare build and idle time, the re-arm prefetch origin, and a tracked-file count

- prepared_checkout_build_ms / prepared_checkout_idle_ms on hits: from arming
  the spare to ready, and how long it sat ready before the claim (0 when the
  create waited). readyAt is recorded in the pool's existing ready handler.
- prepared_checkout_origin gains rearm_then_prefetch: an automatic re-arm that
  the dialog prefetch then asked for too, so rearm means the re-arm alone.
- repo_file_count_bucket replaces the index byte size: the entry count from
  the 12-byte index header, which is the same in every index version; left
  out for a split or sparse index.
- The shared sender never lets a failed send change the create's result or
  error; it logs instead and still ends the create's concurrency membership.
- Tests pin the runtime SSH create's timing hand-off and the throwing-send
  cases on both entry points.

* fix(worktree): leave out the file count under any sparse checkout and time spare builds monotonically

- The repo probe also reads .git/config.worktree, where git sparse-checkout
  --sparse-index writes index.sparse, and omits the file count whenever
  sparse checkout or a sparse index is on in either file, with Git's boolean
  spellings. core.hooksPath there is honoured too.
- prepared_checkout_build_ms / _idle_ms use performance.now(), like every
  other duration; the build is timed from its own start (buildStartedAt).
- The origin field comment names all three values.

* fix(worktree): keep the spare's build time on its first build and count worktrees by lock reason

- prepared_checkout_build_ms runs from the first build's start (including any
  wait for the base fetch it is built on) to its first ready; a later tip
  refresh no longer restarts it, though it still counts as new preparation
  work. prepared_checkout_idle_ms runs from the latest ready (build or
  refresh) to the claim.
- The worktree count reads each .git/worktrees entry's locked file and leaves
  out entries whose lock reason names an Orca preparation, the way the
  listing does, instead of subtracting this process's spares. That covers
  spares from other processes, crash leftovers and spares being discarded,
  and cannot run one low while a spare's admin dir does not exist yet. It has
  its own 1.5 s cap inside the probe.

* ci(release): skip the orcad template for tags that predate it (#24872)

A patch cut from a base older than #24155 has no orcad template source, so
the template job could never pass and every desktop build waited on it.

* fix(runtime): make OMP 18.4 workers ready at the composer and keep stale-title clears display-only (#24295)

* fix(runtime): veto OMP setup by screen and keep stale-title clears display-only

OMP readiness no longer keys on the composer's thinking-effort hint, which
OMP retires after a few uses, hides once a conversation exists and renders
differently per glyph preset. Instead OMP's setup wizard (alternate screen or
a "Setup step N of M" heading) vetoes every ready lane, and OMP's own `π >`
idle title counts for the omp identity only once quiet on a screen read clear
of the wizard. Other OMP titles take the general path again, so the
post-turn `π -` title, 17.x `π:` titles and first-party blocked waits behave
as before. `π >` is no longer explicit idle for every identity.

The stale-working-title clear stays out of runtime records, but display
readers (worktree ps, phone status and titles, terminal list, orchestration
pointer, orphan adoption and reveal titles) now project records through one
display accessor, so they show the cleared title and status again. A title
the clear retired can no longer prove an agent is present; the foreground
process must, which also covers the retained Cursor spinner, so the Cursor
presence exclusion is reverted.

* test(runtime): refuse OMP's setup splash, which has no step heading

* test(runtime): a genuine title retires the stale-working display clear

* test(daemon): record the OMP captures' inherited shrink cursor divergence

* fix(runtime): settle OMP's idle title by its age and veto only its alternate screen

OMP 18.4 re-asserts bracketed paste every second once a terminal answers
its capability probe, which Orca's terminals do, so an idle OMP pane never
went quiet and worker-start still timed out. Its idle title now counts once
it has stood a quiescence window on a screen read clear of the setup wizard.
The setup veto now reads only the alternate screen: the wizard always runs
there, and a 'Setup step N of M' line on the normal screen is an answer's
own text.

* test(runtime): let the grid ingest OMP repaints before the title arrives

* fix(runtime): keep the stale-title clear's process checks and record lifetime

The stale-working-title clear is now an explicit branch instead of an early
return. It still skips the title/status evidence readiness and delivery
read, but runs what main's clear did to re-derive process state: the
foreground-agent re-probe (an exited shell-launched agent loses its
identity) and the completion-race exit check behind a fresh done hook. The
clear now lives on the PTY record, so an SSH relay drop and reattach keeps
the cleared display, and a recreated tracker is seeded from it. Presence
judges a retired title by display ordering, so a renderer pane title older
than the clear cannot prove an exited agent is present.

* docs(runtime): OMP's idle title precedes its setup wizard by its startup tail

* fix(runtime): judge agent presence by the displayed title while a clear stands

A title the stale-working timer cleared used to veto presence outright, so a
live, busy agent whose title cleared to its name and whose process Orca
cannot recognize read as no agent, and the answer depended on whether a
renderer pane was mounted. Presence and the terminal status query now read
the display projection instead, which is what they read before the clear
stopped rewriting records: a cwd spinner still clears to a neutral title, so
the foreground process decides for an agent that exited behind it.

* fix(runtime): compare a cleared title with a lifecycle cleared the same way

The stale-working clear no longer writes the prompt lifecycle, so the
blocked-dialog check compared a cleared title with a still-working
lifecycle and ignored a trust or update dialog painted after the clear:
terminal status said idle, the guarded send accepted, and a mounted pane's
interactive wait went missing. The lifecycle is now projected through the
clear wherever a cleared title is compared with it, as main recorded both
together. That comparison can only report a wait on the user, never idle.

* fix(runtime): verify prompts behind a stale-title clear against main's baseline

Prompt-submission verification read the native lifecycle while a
stale-working clear stood, so output after a swallowed Enter behind a stuck
spinner counted as delivered, and the first spinner frame after the clear
was not a new turn. Its starting status now goes through the same lifecycle
projection the blocked-dialog check uses, and the first working status
after a clear starts a new turn, as main recorded it. Readiness, delivery
and the mailbox still read only native evidence. The blocked-dialog comment
now says the projected pair reproduces main's verdict.

* fix(codex): skip the hook trust RPC when Codex's session index is unreadable (#24604)

An unreadable state DB was read as 'not busy', so the trust grant ran a

callers keep their existing boolean behaviour.

* refactor(cursor): move the desktop-login read onto the shared foreign SQLite reader worker (#24603)

* refactor(sqlite): rename the OpenCode SQLite worker entry to foreign-sqlite-reader (STA-9122)

The worker thread that reads OpenCode's database off the main thread is about
to read other apps' databases too, so its entry is renamed to what it is:
src/main/foreign-sqlite-readers/foreign-sqlite-reader-entry.ts, built as
out/main/foreign-sqlite-reader-entry.js.

Why now: #24572 fixed the Cursor focus freeze with a second, dedicated
worker. Rather than grow one worker per foreign app, the next commit moves
Cursor onto this entry and deletes that worker. This commit is the rename
only; #24572's cursor-desktop-profile-worker-entry lines stay until then.

It moves out of ai-vault/ into a new foreign-sqlite-readers/ module because
it will no longer be session-scanner code; the module will own the readers,
their dispatch, protocol and main-process client.

The entry still routes only OpenCode kinds in this commit. The OpenCode
dispatch, protocol and process entry stay in ai-vault/ and stay OpenCode-only,
because the SSH/WSL relay reader bundles them (build-relay.mjs).

Every reference is updated: electron.vite.config.ts input key, knip entry,
the plain-node entry guard and its test, the asarUnpack list (the scanner
service still spawns this entry under ELECTRON_RUN_AS_NODE), and the
electron-builder test that reads the filename. The filename and the
beside-or-one-up (Rollup chunks) lookup now live in
foreign-sqlite-reader-entry-path.ts, which the OpenCode spawn reuses, plus an
Electron-main resolver that uses the packaged app.asar path.

* fix(cursor): move the desktop-login read from its dedicated worker onto the foreign SQLite reader (STA-9122)

#24572 fixed the Cursor focus freeze (#24360) with a dedicated worker
(rate-limits/cursor-desktop-profile-worker*.ts). Orca already runs OpenCode's
database reads on a worker, and more foreign-app SQLite reads are coming, so
keeping one worker per app means one entry, build input, asarUnpack line, knip
entry and guard line each. This keeps one pattern instead: Cursor's
state.vscdb read runs on the shared foreign SQLite reader entry, and the
dedicated worker, its entry and its config lines are deleted.

What moves:
- The read itself is a pure cursorProfile reader in
  foreign-sqlite-readers/readers/ (was rate-limits/cursor-desktop-state-db.ts),
  run only on the worker. A separate dispatch owns the new kinds and refuses
  an unknown kind. The entry routes OpenCode kinds to the untouched OpenCode
  dispatch, so the relay's OpenCode reader stays byte-identical.
- ForeignSqliteReaderClient gives each reader its own WorkerThreadRequestQueue
  lane (own lazily started, idle-torn-down thread; one shared factory) with
  in-flight dedupe per database path. Any failure resolves to the reader's
  existing failure value and never falls back to the main thread.

Kept from #24572, so every reader gets them:
- Await worker retirement before respawning. Worker.terminate() cannot
  interrupt a native SQLite call (e.g. a WAL-index rebuild), so the old
  thread lives on until that call returns; respawning at once stacked a new
  thread on the same work for every timed-out read (#24572 measured three
  live workers). This belongs in the shared host, which fire-and-forgot
  terminate(): LazyWorkerThreadHost now takes awaitRetirement and refuses to
  spawn until the terminated worker settles, and the queue fails calls closed
  meanwhile. Opt-in, because pure-JS clients (session scanner abort, port
  scan) respawn right after an abort. A rejected terminate() also ends
  retirement, so it cannot latch the reader off (raised in #24572's review).
- 10 s Cursor timeout, 2 consecutive deaths, a queue cap of 8.
- #24572's worker tests, rewritten against the shared client: responsive
  caller plus coalesced probes, unavailable worker without path leaks,
  stalled-worker recovery, no respawn before retirement, dispose settles.

Tests: reader, dispatch, client (timeout, 10 s default, crash, malformed,
unavailable without a main-thread read, dedupe, queue cap, own thread per
reader), queue retirement (stalled and rejected terminate), import boundary,
and an event-loop test reading a ~50 MB WAL with no -shm on a real worker.

* Skip slower root package-store restores in Linux PR jobs (#24896)

* test: advance mocked Claude child exit deadlines (#24897)

* perf(tab-bar): a change to one tab no longer re-renders every tab (#24261)

With many tabs open, a change to any one tab (a retitle, an agent finishing, a tab switch, a git status write, or a browser tab update on SSH and web clients) re-rendered every tab in the strip, so the strip stuttered. Each tab is now a memoized row that re-renders only when its own values change, with stable handlers, a stable drag id list and stable drag sensor options. Editor tabs get their own git status, and mirrored browser tabs keep their page-id list while the ids don't change.

Part of #24241: opening, closing or reordering a tab still re-renders every tab once.

* fix(opencode): read the binder's session store off the main thread; ship the reader worker in orcad (#24638)

* fix(opencode): read the binder's session store on the foreign SQLite reader worker (STA-9122)

Before: the OpenCode session binder listed new sessions from opencode.db with
node:sqlite on the main thread every 60 s (and on SessionStart kicks), so a
large or contended store could stall the app the same way Cursor's did.

After: the read is a pure openCodeBinderSessions reader in
foreign-sqlite-readers/readers/, run only on the worker. The binder's
correlation, pane snapshot and process sweep stay where they were.

- The binder round awaits listSessions and re-checks its generation right
  after, so a stop() during the read discards the round before it touches the
  unbound map or the watermark.
- The client's in-flight dedupe key now includes the cursor, so a stale round
  from before a restart cannot hand its rows to the restarted round.
- Idle teardown is per reader. The binder lane keeps its thread for 120 s,
  longer than its 60 s poll, so the thread is not respawned every round.
- A timeout, crash, malformed reply or unstartable worker resolves to [] (no
  sessions), the value the old read already returned on failure.
- An absent store still reads as [] without a log line, and a permission or
  corrupt-file failure still logs (kept from #24577, now in the reader: it
  stats the path and throws anything but ENOENT/ENOTDIR to the client's log).
- The binder lane inherits #24572's limits from the shared lane: no respawn
  until a timed-out worker has exited, 2 consecutive deaths, a queue cap of
  8. Its timeout stays 60 s, matching its poll.
- dispatch switches on the destructured kind, so a new kind without a case
  still fails to compile.

orcad: the hook server runs there too, so orcad now ships
foreign-sqlite-reader-entry.js beside orcad.js (ORCAD_ARTIFACTS, built as an
orcad child). build-orcad runs a smoke check that starts the built worker
under the build's Node and under the pinned runtime, and does a real binder
read on a fixture DB, a Cursor read of a missing file and an OpenCode history
list. The OpenCode history scanner uses the same entry and was bundled into
orcad without it, so on orcad it always failed closed; it can now run.

Tests: reader (cursor, same-ms ids, OpenCode 2 rows, missing then created,
corrupt, inaccessible directory), retirement gate for the binder lane, dispatch
routing, client lane (rows, failure -> [], dedupe per cursor, own thread, idle
teardown default and override), binder loop with an async listSessions
(failure -> [], stop during the read), orcad path resolution through orcad's
host adapters, artifact list, and the smoke check against good, missing and
non-reading entries.

* test(opencode): cover the binder read deadline with fake timers and name the failure test accurately (STA-9122)

* refactor(ai-vault): delete the unused session-scanner worker thread (#24607)

* refactor(ai-vault): delete the unused session-scanner worker thread

Production always scans through the forked session-scanner service process;
the worker thread was reachable only under NODE_ENV=test or the
undocumented ORCA_AI_VAULT_SERVICE_PROCESS=0 switch, and nothing fell back
to it on service failure. Remove the thread (spawn, client, protocol, entry,
tests), its build entry, knip and plain-node-guard listings, and the
backend switch, so session-scanner-background always routes to the service.

- Move the scan options type to the service protocol as
  AiVaultServiceScanOptions.
- Tests now mock session-scanner-service-spawn, the seam production calls.
- Repoint the hot-path listing reliability gate from the worker-client test
  to the service-client test, which covers the same bounded-queue,
  cancellation, and fault-restart properties for the real executor.

* fix(native-chat): one ordered journal writer (#24127)

* fix(claude): settle a queued send the CLI withdrew from its own cancelled frame

Claude reports each uuid-stamped command's lifecycle (queued, started,
completed, cancelled). A send it withdraws from its queue gets `cancelled`
before the interrupt or cancel_async_message answer, so a lost or failed
answer no longer leaves that send pending: it settles as withdrawn, with the
same reason and words as the receipt path.

A command the CLI already started also ends `cancelled` when its turn is
interrupted or fails, so `cancelled` after `started` is not a withdrawal;
an echoed send has left the waiter lists and is never reached.

Tests replay real 2.1.280 captures, scrubbed.

* fix(claude): release a doubted send when the CLI reports its session idle

A Claude send whose write ended in doubt is recorded `unknown`, and a live
`unknown` reads as work still owed, so the chat showed Working until the
child exited. Claude sends `session_state_changed idle` only once its whole
queue has drained, so it can no longer be holding that send. The runtime now
routes that report to the host's existing release, the same one Codex's
thread-stopped report uses; it retires `unknown` only, never `pending`.

* fix(claude): keep a command's started mark when a redelivery re-emits queued; fixtures name msg_lifecycle_v1

* fix(claude): settle every terminal lifecycle state of a send the CLI never echoed

A send the CLI started, then cancelled before any echo, stayed pending: it may
already be in the conversation, so it is released as doubt (unknown, recovered),
never withdrawn and never re-sent. A late echo still accepts it.

The 2.1.280 schema has two more terminal states. `discarded` (the CLI ended its
session with the send still queued) settles as not delivered; `refused`
(declined before it queued) settles as not accepted by the provider. After
`started`, either one is doubt, as `cancelled` is.

The late-settlement path gains an `unknown` outcome, which the host records as
released doubt.

* fix(claude): release a send the CLI took but left unanswered when it goes idle

`session_state_changed idle` comes only once the CLI's queue has drained, so a
send it took that is still unanswered there got no echo and never will: a turn
that throws can leave `started` with no terminal state. Idle releases it as
doubt.

What proves the CLI took a send is its lifecycle frame. On a CLI that reports no
lifecycle, it is the send's place on stdin: one whose write finished before an
interrupt went out was read before the interrupt was, so the first idle after
that interrupt releases it too. A send armed ahead of the interrupt but written
after it is left alone, since the CLI may still run it.

* fix(native-chat): keep the idle sweep off a Claude child that holds a send

A Claude retrying a rate-limited request has taken the send but echoes nothing,
so no turn row exists yet and the sweep rested the child after the idle window,
turning the send into doubt. The adapter now reports whether the CLI holds a
send (lifecycle `queued` or `started`, not yet echoed or ended), derived from
the live waiters, and owed work counts it.

Nothing is stored: every held send leaves the live set on its echo, its
terminal lifecycle state, the CLI's idle, or the child's exit, so the hold ends
with the send.

* fix(claude): count only a started send at idle and as a held send

2.1.280's end-of-turn cleanup can report idle before it re-reads its queue, so
a send read in that window goes queued, idle, started. Releasing every taken
send at idle doubted that live send and dropped Working. Only a `started` send
is released at idle or keeps the child from the idle sweep; a `queued` one ends
by starting and echoing, by a terminal lifecycle frame, or with the child.

The stdin-order path for CLIs without lifecycle frames is removed: a doubted
send retired there disables content matching on CLIs that mint their own echo
ids, and no Orca failure called for it. Those CLIs keep the earlier behaviour.

Comments that said only a failed write or child exit ends a waiter, or that
idle comes only once the queue has drained, now say what ends one.

* docs(claude): say only what the CLI's lifecycle frames and idle actually prove

* fix(claude): hold the idle sweep while Claude has a send queued, not only started

The sweep rested a child whose CLI had queued a follow-up behind a turn, dropping
the send it had already taken. The hold now spans the CLI reporting it took the
send until its echo, a terminal lifecycle state, or the child's exit. The idle
release still covers only started sends: 2.1.280 can report idle before it
re-reads its queue.

* refactor(native-chat): give provider-proven late dispatch settlement its own module

* test(claude): pin a steer a Stop interrupts after it started as doubt, not withdrawn

* fix(native-chat): one ordered journal writer

Every journal write, streamed or direct, lands in the chat's one write queue
in the order it is issued, and has landed in the fold when its call returns
(except while an owed import is paid, when it lands in queue order). The event
sink stops being a queue ahead of it; journal-write coalescing, which moved a
replaced write to the tail, is removed; closing a sink no longer loses writes
already handed over. The ten flushStreamedEvents patches go. A streamed text
item takes its place at its first delta, so a direct write inside the
coalescing window never lands above text already streamed. A Stop interrupts
whatever its bookkeeping writes do.

* fix(native-chat): a failed Stop holds the lane until its queue pause lands

A Stop whose note write or stop call failed skipped the wait for its
withdrawal and pause, so the lane freed first; with writes queued behind
owed work, the drain could hand the waiting card to the agent after Stop.

* fix(native-chat): a journal write body is typed synchronous

The queue's ordering rule needs every write body to finish before it returns;
serialize still took a promise-returning body, so an await inside one would
let a later write land first. The body type now refuses a promise.

* fix(native-chat): a stream's first window snapshot always lands

The first-delta write counted as the growth checkpoint, so the window's
snapshot was skipped until 32 more characters arrived: a stream showed only
its first token, and a Codex reasoning row could sit as an empty aside. The
coalescer now marks the row-creating emit and the first snapshot after it,
and both providers' growth throttles write those.

* test(native-chat): streamed text rewritten in place above a Stop note

Covers a stream whose later deltas wait in the window across a Stop, for
Codex and Claude, and a Codex item completed inside the window.

* chore(native-chat): drop comments that still describe coalesced journal writes

* fix(native-chat): type the draft-table write body synchronous too

* fix(native-chat): an empty delta owes no streamed-text emit

The opening snapshot is forced past the growth rule, so an empty second
Codex delta rewrote the row with identical text. The coalescer now marks a
stream dirty only when a delta adds text.

* fix(native-chat): a mutation's open pays an owed import first

With the flushes gone, a Stop naming no turn, a goal set or a /clear could
read the fold while provider rows still waited behind a restore's owed
import: the Stop answered cancelled:false and interrupted nothing. The open
every mutation shares now waits for the import, as a reader's does; a failed
import is reported and never refuses the mutation.

* chore(native-chat): whenImported says mutations await it too

* test(native-chat): a Stop interrupts before its withdrawal or pause settles

Pins the order for a write that is held and then fails, for a Stop naming
its turn and one naming none.

* test(native-chat): a Stop ends a starting child before its withdrawal or pause settles

* test(native-chat): Stop order tests wait for the interrupt, not a 50 ms timer

* test(native-chat): settlement-order test reads rows through the journal row parser

Replaces a Reflect.get field walk, which the low-evidence audit rejects, with
parseJournalRow and the named row types.

* fix(native-chat): an empty delta still owes its emit, just not a forced one

The previous fix stopped an empty delta from marking the stream dirty, which
broke the pinned contract that an empty stream is snapshotted and flushed.
The coalescer now marks a stream dirty on every delta and tracks separately
whether its text changed since the last emit; only a changed snapshot is
the opening one that skips the growth throttle.

* revert(native-chat): drop the first-text row write from the delta coalescer

The immediate first-delta emit (and the opening flag and counters it needed)
had no Orca-observed failure behind it and added a journal commit per
streamed item. The coalescer, the Claude checkpoints and the tests that
pinned the first-text row go back to main's behaviour; the one ordered
writer, the sink hand-off and the Stop rules stay.

* fix(worktrees): list a folder once when git reports it twice (#24357)

When git lists the same folder twice (a leftover worktree registration that points at the main checkout), Orca's runtime listing turned each line into its own worktree with the same id, so `orca worktree current`, `active` and `branch:` failed with selector_ambiguous, and paired clients saw a duplicate row. The runtime scan now keeps git's first row per folder, the rule the desktop sidebar already uses. Separately, for a bare or separate-git-dir repo added through a linked worktree, the scan no longer relabels the main row with that worktree's folder (it relabels only when the folder's git dir is the common git dir), so the worktree keeps its own row and branch in the CLI and the sidebar. No extra git command runs.

* fix(worktrees): a worktree delete git fails partway stays listed and can be retried (#23952)

* fix(worktrees): delete removed checkouts in git, not in Orca's file pool

Local worktree removal renamed the checkout into a sibling trash root and
deleted it in the background with a recursive fs.rm in the main process.
That queued one request per entry on libuv's shared 4-thread file pool, so
for minutes every other async fs call in the main process (the agent-session
store behind chat sends, file explorer reads) waited behind the delete.

`git worktree remove` now deletes the checkout inline in git's own process
again, so the card stays in its Deleting state for the length of the delete
while Orca's file pool stays free. No timeout applies to the call, so a
large delete is never killed halfway.

If git reports success but the path still exists (Git for Windows leaves
junctions and their parent directories in place), the leftover is deleted
with the existing removeHostTree; WSL checkouts stay with the distro.

Nothing creates trash any more: the scheduling queue, rename/restore
helpers and the trash_rename span are gone. The startup sweep stays to
drain entries older releases left behind, and now removes each emptied
trash root so the obligation ends.

* fix(worktrees): let Git delete Windows checkouts with long paths enabled

Removal now always runs Git's own recursive delete, and worktree creation
checks out with core.longpaths on Windows, so a deep checkout Orca created
could fail to delete with "Filename too long" (#6433). The Windows recovery
then finishes the delete but keeps the branch. Pass the same command-scoped
core.longpaths option to `git worktree remove` so Git can delete what it
created.

Also point the CI shard timing entry at the renamed real-git removal suite.

* fix(worktrees): keep an inherited GIT_ASK_YESNO out of the worktree delete

Git for Windows asks $GIT_ASK_YESNO whether to retry when a file stays
locked during a recursive delete. Orca's git env inherits the user's
environment, so an inherited value would run an arbitrary prompt program
in the middle of a removal. Drop it for the removal call only.

* perf(worktrees): run worktree deletes under their own limit, outside git admission

`git worktree remove` now deletes the whole checkout in Git's own process,
which takes 20-35 s on a large tree. It took a general git admission slot at
status tier for that whole time, and that cap is as small as two slots on a
machine with six or fewer cores, so two deletes blocked every status read.

Deletes now skip general admission and queue under their own limit of two
per host instead: two concurrent deletes already saturate one disk, and more
only slow each other down. Leftover cleanup runs inside the same slot.

* fix(worktrees): delete removed checkouts in the background and mark them removing

Since the checkout is deleted by `git worktree remove` in Git's own process,
a large delete takes 20-35 s. Answering the request only after that made web
and mobile (30 s), paired desktop (60/180 s) and the CLI (60 s) report a
failure for a delete that was still going, and mobile silently re-showed the
row.

The request now does everything that can refuse (lock, cleanliness, archive
hook, watcher/terminal gate, terminal stop, shared-link unlink), records the
removal in an in-memory table on the host and answers `removing: true`. The
delete, branch cleanup and metadata purge run after it in the same order as
before, and the watcher/terminal gate stays held until they finish.

- Listings mark rows in the table `removing` for clients that advertise
  `worktree.background-removal.v1` (the desktop renderer, paired desktop and
  web), and leave them out for everyone else (older clients, mobile, the
  CLI), which already dropped the row when the request answered.
- The outcome (removed, with any preserved branch, or the error) rides the
  existing worktrees-changed event as an optional field, sent after the row
  has left the table.
- A repeat delete while Git runs joins it. A create at the same path or with
  the same branch is refused with "Cleanup is pending; try again shortly";
  create's name search skips the path, so generated names move on.
- Nothing is persisted: after a quit or crash Git still lists the checkout
  and it can be deleted again. WSL checkouts still delete inline.
- `orca worktree rm` says the checkout is still being deleted.

* fix(worktrees): keep the existing Deleting card until the host's Git finishes

The host now answers a local worktree delete on acceptance and deletes in the
background. The renderer keeps the existing delete state set until the host
publishes how it ended:

- The delete that asked waits for the outcome on the worktrees-changed event
  (local IPC or the paired runtime's client event), then runs the same
  teardown, preserved-branch toast and card error an inline delete did. If
  that event is lost to a dropped connection, a listing that shows the row
  gone after it was marked removing finishes the wait, and one that shows it
  back without the marker fails it.
- Any other renderer (a reload, a paired desktop, web) sets the same delete
  state from the host's `removing` marker and clears it when the marker goes.
  A failure the host publishes lands on that card's existing error.
- Web advertises `worktree.background-removal.v1` so the host sends it the
  marker; paired desktop does through the Electron capability list.

No new component, style or state: the card reads the delete state it always
did. A host that predates this answers when done without `removing`, and the
renderer takes that as finished, as before.

* test(worktrees): type the removal harness and projection for the node typecheck

* fix(worktrees): don't fail a delete retry with an earlier attempt's buffered failure

A background removal's outcome that reached this renderer with no waiter (another client's
delete, a host-marked card, or one already settled from listings) was buffered for 60 s and
consumed by the next delete of the same workspace, so retrying a failed delete failed at once
with the old error while the host was deleting. Drop the buffered outcome before sending the
request; only an outcome that arrives after it can belong to it.

* fix(worktrees): let only a gap in host events settle a background delete from listings

Git unlists the checkout before the host deletes the branch, cleans the push target and purges
metadata, and the worktree-directory watcher refetches within 250 ms. The renderer read the
missing row as a finished delete, so the waiter resolved without the preserved branch (no
toast) and a failure in those last steps showed as success; the real outcome was then dropped.
The listing fallback exists only for a lost outcome event, so it now applies only after this
host's event stream had a gap: a new subscription or a replay after reconnect.

* perf(worktrees): let a bulk delete start each same-repo checkout delete once the host accepts the last

A bulk delete ran one worktree at a time per repo (#2259, for packed-refs and ref-lock races in
branch cleanup). With Git now deleting each checkout for 20-35 s before the request settles, N
worktrees in one repo took N times that. The renderer now queues same-repo deletes only until
the host accepts each one; a parent still waits for its nested children to finish. The host
serializes the branch cleanup step per repo itself, which also covers removals started by
different clients.

* test(worktrees): pin the host platform in the mocked removal suites so they pass on Windows

Removal now passes -c core.longpaths=true on Windows, so the exact-argv
assertions and command-keyed mocks never matched there (17 failures on a
Windows host). Pin darwin as the add-worktree suites already do, and drive
the one Windows-specific case through the same spy.

* test(worktrees): type the blocked git remove result instead of a broad object

The anti-slop static-analysis gate rejects `object` parameters.

* test(worktrees): clear the changed-code quality gate in the removal suites

Merge the duplicate node:fs import, build the mock child without a cast, read
worktrees:list rows through one typed helper, and give the remaining casts a SAFETY line.

* fix(worktrees): record each background delete durably and finish it after a quit or crash

A quit mid-delete left git to finish the checkout on its own while the branch
delete and metadata purge never ran; a crash left a normal-looking row. Each
accepted local removal now writes a record beside the profile state before git
starts, clears it on success or failure, and the host runs the same delete
again for any record left at startup, re-deriving what remains from git and
disk. An orderly quit stops the checkout delete without waiting for it.

* test(worktrees): type the interrupted-removal assertions for the node typecheck

* fix(worktrees): finish an interrupted delete that already removed the checkout's .git file

Quit stops git worktree remove mid-delete, and Git deletes the checkout's .git
file wherever it falls in directory order. Git then refuses the checkout
("validation failed ... .git does not exist") on every retry, so the startup
finish failed and the row could never be deleted from Orca. A registered
checkout this record owns that has lost its .git file now finishes like an
unregistered one: leftover files, prune, then the branch.

* fix(worktrees): let Git finish an interrupted delete, and never take a different checkout

A quit or crash that stops `git worktree remove` after it deleted the checkout's
.git file left a registered checkout Git refuses to remove. The previous fix
deleted that leftover inside Orca's process, which is the bulk delete this
change exists to avoid (and on Windows the leftover can be most of the
checkout). The startup finish now rewrites the missing .git file from Git's
own admin entry for that path and lets `git worktree remove --force` delete
it. `git worktree repair` is not used: it also re-points every other
registered path, including a checkout another repository now owns there.
Orca deletes the leftover itself only when no admin entry claims the path.

The startup finish forces, so it now leaves the path alone when the checkout
there is not the one recorded: a registered worktree on a different branch or
head, or a `.git` at a path Git already unregistered. The record is dropped and
the card shows why.

The record write before Git starts is now bounded (2 s, logged when exceeded)
so a stalled disk cannot hold the delete, and the outcome is published before
the record's clear reaches disk.

* test(worktrees): compare worktree paths by value and tear down with Windows lock retries

Git prints forward slashes in `git worktree list` on Windows, so the real-Git
removal suites never found a joined path there: positive checks failed and
negative ones passed without proving anything. They now compare Git's parsed
rows by value. Teardown uses the shared retrying removeTree, since Windows can
hold the deleted checkout busy for a moment after Git exits. Adds a
relative-path worktree case for the .git restore (skipped before Git 2.48).

* fix(worktrees): reply to a worktree delete when it has finished, not on a broadcast event

A current client's delete request now waits for the host's background delete and gets its real
result (removed, a preserved branch, or the error) as the reply, the way it did before the delete
moved off the request. A request that arrives while the delete runs joins it and gets the same
result. Every other view keeps reading the host's `removing` marker: the row leaving means the
delete finished, and the row listed again without the marker shows "The delete did not finish.
Try again." on a card that view had marked Deleting. A request whose reply is lost (a timeout or a
dropped connection) settles the same way from a fresh listing instead of reporting a failure.

Clients without the background-removal capability (mobile, the CLI, older desktops) are still
answered on acceptance and have rows under removal left out of their listings.

This removes the outcome on worktreesChanged and everything it needed: the renderer's outcome
waiters, early-outcome buffer and TTL, per-host event-gap generations, the request pre-registration,
and the accept callback bulk delete used. Bulk delete runs same-repo deletes in parallel only on
this machine, whose host serializes branch cleanup per repo; SSH and paired hosts stay serialized.

* test(worktrees): type the pending-removal host id in the background-removal suite

* fix(worktrees): answer a delete request even when a concurrent removal of the same worktree replaced its record

The desktop app's removal and the runtime removal (CLI, paired clients) coalesce separately, so
both can be accepted for one worktree. The second replaced the first's record, and the first
delete then finished without resolving the request waiting on it, leaving the desktop card on
Deleting indefinitely. Each delete now settles the request it was started for.

* fix(worktrees): run same-repo removal archive hooks and teardown one at a time on the host

Local bulk delete now sends same-repo removals in parallel, so their archive hooks, terminal
teardown and preflight ran at once; a hook that writes refs can race the repo's ref locks
(#2259). The host now serializes each local removal up to acceptance per repo, for every
client; Git's checkout delete still runs in parallel under the delete limit.

* fix(runtime): keep waiting worktree deletes out of a host's foreground call slots

worktree.rm now replies only after Git deletes the checkout (up to minutes), so on paired
desktop and web each waiting delete held one of the host's 8 foreground call slots, and a
bulk delete queued listing refreshes and every other foreground call behind it. Deletes now
run in their own lane with the same bound; the 2-slot background lane stays for status polls.

* fix(worktrees): join a same-worktree delete accepted while a removal waited its repo turn

The desktop app and the runtime (CLI, paired clients, web) check for a running delete before
they queue for the repo's acceptance turn. A delete of the same worktree from the other path,
accepted while this one queued, was missed: this request re-ran the archive hook, stopped the
terminals again and started a second `git worktree remove` on the directory Git was deleting.
The queued acceptance now re-checks and joins the running delete.

* fix(worktrees): fence a resumed delete's checkout from startup, and drop rows a listing read before the delete finished

A delete a quit or crash interrupted took its terminal and file-watcher gate only when the resume
job ran, after the first window was shown; session restore could open a shell or watcher inside the
half-deleted checkout first, and on Windows that handle can fail the resumed git delete. Loading the
records now fences each recorded path, and the resumed job takes the fence over in the same tick it
takes its own gate.

A listing that read git's registration before a delete finished, and replied after the removal
record cleared, returned the row unmarked, so other views briefly showed "The delete did not
finish". Listings now capture the pending removals before reading git and leave out a row whose
delete finished successfully since; a row whose delete failed stays listed as before.

* test(worktrees): keep git's auto-maintenance out of the real-git removal suite

CI's Git 2.55 failed the file-pool test in teardown with ENOTEMPTY on the scratch repo's
objects/pack after the test body passed: the 3,000-file commit's detached auto-maintenance was
still writing a pack. The scratch repo now disables auto-maintenance and auto-gc.

* fix(worktrees): one archive-hook approval covers a same-repo bulk delete again

Local same-repo deletes now start together, so each queued its trust prompt with a state snapshot
taken before the first prompt was answered; approving the first still showed the same prompt once
per remaining worktree. The queued check now reads the store when its turn comes.

* fix(worktrees): a delete Git fails partway stays listed with its error; Delete retries it

`git worktree remove --force` drops the checkout's registration even when it
cannot delete a file (root-owned files, `chflags uchg`, a read-only Windows
directory). Orca lists workspaces from Git, so the row vanished after the error,
leaving the checkout, the branch and Orca's metadata with no way to retry.

- A background delete that fails with the checkout still on disk, unregistered,
  and still the removed checkout's own leftover keeps its durable removal record
  with the error (`failure`) instead of clearing it. Every other failure clears
  it as before.
- Local listings (desktop list/list-all/detected, runtime list/ps/detected)
  add a row for each such record, carrying `removalError`, and for a pending
  removal whose checkout Git no longer lists (shown as removing).
- Delete on that row (desktop IPC and runtime worktree.rm) runs the recorded
  removal again: terminal teardown, then the leftover, prune, branch and
  metadata, under the per-host delete limit.
- The record ends on a successful retry, when the checkout is gone (listing or
  startup)…

* fix(source-control): generate PR details before Create PR on a ready branch (#24215)

* fix(source-control): generate PR details before Create PR on a ready branch

A pushed branch sent the placeholder title and empty body, skipping the
configured agent. A run Create PR submits unreviewed keeps the user's base
and never unchecks Draft; the Generate button is unchanged.

Fixes #22824

* docs(source-control): correct the auto-submitted Draft rule comment

* fix(source-control): never let generated details uncheck the user's Draft box

A Draft choice made before generation started was unprotected: the form only
keeps fields whose revision changed *while* a run was in flight, so a user who
checked Draft and then pressed Generate had the box silently unchecked by an
agent answering draft:false, and the next Create PR opened a real review ready
for review. Scope the rule to provenance rather than the in-flight window, and
apply it to reviewed runs and the prepare-branch route too, so the agent can
still flag unfinished work but never reverts a choice the user made.

* test(source-control): cover the Checks panel create-after-run and superseded-run guards

Two guards had no failing test. The Checks panel's Create PR must still send
the finished run's details while its last render shows the run as generating,
or the click silently creates nothing. Each panel's generation must return no
result when a later run replaced its record (Stop, then Generate finishing
first), or the stopped Create PR click would open a PR with the later run's
details.

* fix(source-control): don't reveal a background-created PR over another worktree

Create PR on a ready branch now waits for the agent, and the create still
runs if the sidebar panel closes meanwhile. When it finished, it always
opened the sidebar on Checks (and, with "open after create", the review),
even if the user had switched to another worktree, so Checks showed the
wrong worktree and the in-app link route switched the user back.

Reveal only when the created review's worktree is still selected, or the
panel that made it is still mounted, like the prepare-branch route.

* fix(source-control): keep Create PR in flight while the agent writes the details

Create PR on a ready branch generated the details and then created nothing,
with no message. When generation ended, Source Control's eligibility check
restarted and cleared the eligibility, and the create, which reads the panel's
latest state, returned early on the missing eligibility.

The click now stays in flight from the start of generation until the create
settles, as the prepare-branch route does, so the eligibility check stays
paused and the create sees the eligibility it started with. Repeated clicks
are counted so one returning early can't release another's hold.

* refactor(source-control): move Checks created-review linking into its own hook

No behavior change. The Checks panel's create hook was at its 400-line limit;
linking and refreshing a created review now lives in
use-checks-panel-created-review.tsx, the way Source Control keeps it in
use-hosted-review-created.ts.

* fix(source-control): finish a started Create PR run for the branch that was clicked

After the agent wrote the details, Create PR read the panel's latest render
instead of the state at the click. That render could have lost its
eligibility (no PR, no message), still show the run as generating, or show
another branch. Navigating away also gave opposite results: with the sidebar
open on another worktree no PR was made; after closing the sidebar first, it
was.

The create now always runs through the click's own closure, so a started run
creates the PR for the branch that was clicked wherever the user went, like
the prepare-branch route. The reveal still follows the selected worktree, so
nothing opens over another one. The "still shows generating" bypass in both
panels is gone: the click's render never shows the run as generating.

In the Checks panel, a create that returns after the panel moved to another
worktree still links the review to the clicked worktree and clears its
push-first flag; only the in-flight state, errors, opening the review and
the GitLab checks refresh are skipped, since they belong to whatever the
panel now shows. The same holds for a push-first create whose push finishes
after the panel moved.

* refactor(source-control): let the Create PR click own the in-flight flag

The click already kept Source Control's create in flight through generation,
so the composer stays up instead of closing while eligibility refreshes. It
did that with a per-worktree click counter next to the create's own in-flight
flag, so a repeated click that returned early couldn't end the first click's
hold.

Now the click owns the existing in-flight flag from the click until the
create settles, and a click while it is set is refused before it touches
anything, so the counter is gone. This matches what the UI already did:
Create PR is disabled while the flag is set, including after Stop until the
stopped request returns. Since the create now runs through the click's own
state, the hold only keeps the UI steady; it no longer decides whether a PR
is created.

* docs(source-control): describe the created-review foreground check by what callers pass

The Checks panel now passes whether it still shows the created review, not
just whether it is mounted, since a mounted panel can have moved to another
worktree while the create ran.

* fix(source-control): release Create PR as soon as Stop lands

After Stop, Source Control's Create PR stayed disabled ("Creating...") until
the stopped generation request came back. Locally that is under a second, but
when the cancel can't reach a slow or disconnected remote host the button
stayed disabled for up to the 75 s generation timeout.

A generation run's outcome now settles as soon as its record stops running,
not when the request returns. Stop marks the record canceled at once, so the
click that started the run ends, its hold is released, and the next click
submits the form as shown. The stopped request still finishes in the
background; its late result is dropped because the record is no longer
running for that request. Both panels' generation handlers use the same
helper.

* test(windows): record native PTY stress lifecycle milestones (#25042)

<!-- /orca-pr-loc -->

## ELI5

When a Windows terminal stress test stalls, its old log cannot show where progress stopped. The test now records bounded, sanitized lifecycle observations while keeping its existing assertions and timing.

## What Changed

Record output-pipe, worker, native exit and final callback milestones, pending state at existing deadlines, and hashes of the native addon and supporting files. Redact addresses and credentials even when terminal controls split them, preserving the controls’ positions. Keep the warmup survivor and newest 31 terminals; later terminals still receive observers, with omissions counted explicitly.

## Why

[The failing Windows job](https://github.com/stablyai/orca/actions/runs/37132029374/job/111229398978) had one silent terminal and at least one undrained callback. [An earlier passing job](https://github.com/stablyai/orca/actions/runs/37123932023/job/111205697896) used the same source and cache inputs, without a loaded-addon hash. Observing the existing objects supplies missing evidence while preserving the gate. Bounded recent records retain the terminals most likely involved in a late failure.

## Linked Issue

Diagnosis of PR #25031’s Windows package failure. This does not claim that the original native cause is fixed or close a product issue.

## Visual Proof

N/A — test diagnostics add no UI or interaction change.

## Testing

- [ ] I manually tested these changes locally
- [x] Automated tests added and updated for reproduced failures.

On the exact previous public helper, eight strengthened controls failed and six passed. They reproduce control-interrupted credential/address leaks, omitted late terminals after eleven rounds, and late state after the 256-milestone cap. Independent review then reproduced six more leaks on the intermediate helper: usernames and hostnames masked only part of an email. The final helper runs the existing same-length redactor a second time, removing the remaining private domain while preserving controls and OSC framing. Those six before failures and two credential-overlap controls are retained. Corrected source `5037c18a898571539ade5336ad3519cd49dfb20f` passes 171 controls in four files, including all 22 observer controls, the full anti-slop audit, syntax/AST checks, focused format/lint and six quality gates.

The previous public source `f1ed3e97` passed [actual Windows CI](https://github.com/stablyai/orca/actions/runs/37136703455/job/111243011997): 25 PTYs, eight rounds, 526 passing tests and 26 skips, plus build, package and smoke checks. Its native stress/driver files remain exact here; the observer has changed, so fresh normal CI must qualify this complete correction. The passing run’s native-addon hash differs from the historical failure; it does not explain that failure.

## Review

All four original diagnostic files and public ancestry are retained; all 32,245 paths outside that scope match main `786a040b`. The existing redactor runs twice on a view with presentation controls removed, then controls are restored at their original positions; OSC framing separates title payloads from adjacent text. Logs retain 32 terminal records and 256 milestones with explicit omissions, plus bounded final snapshots. The native callback preserves its receiver, arguments, result and thrown errors; error observers preserve unhandled-error behavior.

Native assertions, deadlines, input, concurrency and cleanup remain exact. Companion hashes identify file bytes rather than in-memory DLL equivalence. The original native cause remains unverifiable.

## Agent skill upstream boundary

- [x] Not applicable; no upstream skill source is copied.

## Notes

No production API, RPC, native patch, dependency or workflow change. Blank output or a missing callback is not evidence of process death. Local helper controls run on macOS; the existing real ConPTY gate exercises Windows.

## Checklist

- [x] Small, focused diagnostic scope.
- [x] Explained the before/after, mechanism and choice.
- [x] Visual proof N/A with reason.
- [x] Self-reviewed privacy, bounded logging and callback behavior.
- [x] Cross-platform and remote impact considered.
- [ ] Fresh normal Windows CI must qualify the complete corrected source.

* fix(cli): orca file open opens PDFs and other binaries like the File Explorer (#24445)

files.open gated the desktop open on the mobile preview list, so PDFs returned opened:false with ok:true. The host now opens every file after an existence/directory check; the CLI fails loudly if an older host still declines.

Fixes #24328. Builds on #24331.

* Update README downloads badge

* refactor(orchestration): one function for six agent-to-agent sends (#24901)

* refactor(orchestration): send every agent-to-agent message through one sendAgentTurn

The structured mail-pointer lane and the structured worker preamble each carried a copy of
"send, wait out a pending start, read the verdict", and four dispatch-preamble sites typed into
a terminal directly. They now share sendAgentTurn, built from host.send, the host's settlement
waiter and sendTerminalAgentPrompt. Every caller passes delivery 'now', so nothing sends
differently; a source-scan ratchet keeps new direct sends out.

* test(orchestration): the refusal fixture uses a real wire refusal code

* fix(orchestration): derive the send fingerprint inside sendAgentTurn and pair target with turn

A `queue` send was refused by a real host: callers supplied a fingerprint over the body alone
while the host digests body and delivery. sendAgentTurn now builds the envelope with the
composer's own builder (extracted to structured-agent-session-send-mutation), so the fingerprint
is always over exactly the fields sent; `now` sends keep the identical digest. The pointer lane
no longer carries a fingerprint it cannot get right.

sendAgentTurn takes one argument, a union on kind that carries its own target and turn, resolved
by an exhaustive switch; the terminal turn names its purpose (only the dispatch preamble today)
instead of every terminal send inheriting the task lead line. A queued outcome keeps the host's
draft receipt, and both structured callers read outcomes exhaustively with unchanged behaviour.

The boundary test now also fences direct structured host sends, catches optional, bracket and
bound member uses, has a planted-offender self-test, and pins the unmoved terminal mail pointer
and agent-teams tmux senders.

* fix(orchestration): keep federation.ts under max-lines and satisfy prefer-template in the send ratchet

* fix(orchestration): wait on the answered submission's id when a replayed queue turn was already handed off

* test(orchestration): pin that a replayed queue turn waits for its hand-off to settle

* feat(native-chat): a Claude subagent waiting on a permission prompt reads as waiting (#22634)

* feat(native-chat): a Claude subagent waiting on a permission prompt reads as waiting

A subagent's permission request reaches the parent session's callback naming the
subagent that asked (agent_id) and the tool call it gates (tool_use_id). The
pending request is recorded with the asking agent. On every drain the child-work
producer re-derives which children a pending request blocks and hands that set
to the Claude child decoder, the one owner of each child's live edges: a blocked
child reads waiting on every live edge it reports, and a child that starts or
stops waiting is a live edge of its own. Answering, denying or cancelling the
request returns the child to its prior live state; nothing is stored beyond the
pending requests.

A live task_updated carrying an error now reaches the record as the child's last
message, without an ending or a new state.

The replay test drives a scrubbed capture of the real CLI (foreground allow,
deny, interrupt, background allow, and the main agent's own request) through the
real adapter into the host's child records.

* test(native-chat): a subagent's request names it before its tool call is read

* docs(agent-status): a subagent asking for approval waits in every lane; the parent row keeps the session's own attention

* test(native-chat): hand canUseTool the asking agent without widening the helper's cast

* test(native-chat): an interrupted Claude subagent settles cancelled, not failed

A captured interrupt shows the spawn call's error result ("The user doesn't want
to proceed…") arriving before the subagent's own `task_updated {status: killed}`.
The spawn result ends nothing (the child ends only on its own terminal frame), so
the child stays live until its `killed` status settles it cancelled. A genuine
failure, captured with the subagent on a model that does not exist, sends its
`failed` status before the error result and still ends failed. Both captures now
replay through the real adapter into the host's records.

* fix(native-chat): a Claude subagent's prompt makes the parent row wait, not block

A subagent's pending prompt made the whole session `attention`, which reads as
the main agent's own `blocked` and outranks the fold's waiting arm, so the
parent row read blocked where a CLI Claude parent reads waiting. The main
agent's state now reads only its own pending prompts.

- A Claude prompt row carries the linkage of the agent that raised it: the one
  the permission request names, or the owner of the tool call it gates. The
  same join decides which child reads waiting, so the two cannot disagree.
- The status summary projects the session's own status from root prompts only;
  every other reader (delivery gates, teardown, restart) still asks whether
  anyone is waiting on a human.
- An answer keeps the prompt row's linkage by the journal's own rule: a
  revision that names no producer keeps the row's existing one.
- The child-tool queries gain the prompt's producer, so a prompt row and a
  child record answer "which agent" from the same join.

* test(native-chat): say which ids the permission capture scrubs and which are its own

* fix(native-chat): the status clock dates attention by the session's own asks only

The session's status is now `attention` only for its own pending prompt, so the
clock's fallback to a subagent's ask could no longer be reached, and it read the
journal by a different rule than the status it dates. Both now read root prompts.

The journal also stamps a Codex subagent's prompt with its thread (#22532), so a
Codex child's approval is that child's wait in the Codex lane too. Two tests
written for the earlier rule are updated: a subagent's ask leaves a running
session `working` on its turn's clock, and a Codex child's answered approval
leaves the settled parent's Activity row done with nothing unread.

* fix(native-chat): a completion still says the user is asked when a subagent asks

The turn-completion feed marked a completion `awaitingUser` from the status
summary's `attention`. The status now means the session's own agent is waiting,
so a subagent's pending approval stopped reaching the completion. The projection
now also says whether anyone is waiting on the user, as the delivery gates,
teardown and restart ask it, and the completion reads that.

The waiting-subagent replay answers its prompt with the adapter's current
response shape.

* revert(native-chat): a live Claude task's error stays out of the child's last message

No capture shows a live task_updated carrying an error, and it is unrelated to
a subagent waiting on a permission request; it leaves this PR.

* test(native-chat): settle the Claude session's startup before replaying a subagent's request

A startup frame drained child work during the first await, so answering a
request freed the child even with the answer's own republish removed.

* fix(native-chat): a Claude subagent's prompt row names it as its other rows do

The prompt row stamped only the asking agent's id, so a nested subagent's
request lost the agent that spawned it, its spawn call and its run. It now takes
the linkage the asker's own rows take: the gated tool call's, when that names the
same agent, else the one resolved through the agent's spawn call. The provider's
agent id stays the asker's id.

* fix(native-chat): a subagent's request makes the parent row wait without a child record

The parent row learned that a subagent needed the user only from that
subagent's child record, so a request no record carried (a Codex child the host
never registered, a Claude task past the live cap) left the row working or done
while the approval card sat in the chat.

"Someone in this session must answer" is now one derived session fact. The
projection names two facts instead of a mode flag: the main agent's own status
(attention only for its own request) and structuredAgentSessionAwaitsUser (any
pending prompt). The status summary publishes the second as an optional
awaitsUser, and the shared fold reads it: the main agent's own ask is blocked,
otherwise awaitsUser or a waiting child record makes the row wait. Every caller
picks the fact it means: the completion edge's awaitingUser and the delivery
gate read awaitsUser; the quit snapshot folds the same two inputs the sidebar
does.

* fix(native-chat): a client that predates awaitsUser still reads a subagent's request as attention

A status summary's status is now the main agent's own, so a client built before
the split would read a subagent's request as working (or idle) and fold it with
code that has no awaitsUser input. Clients advertise
agent-session.status-awaits-user.v1; at agentSession.subscribeStatus the host
sends any client that does not the pre-split summary: attention whenever
awaitsUser is set, without the main agent's own tool line, verdict and clock.
The feed and every in-process reader keep the canonical summary. Transitional,
like the turn-item downgrade.

* test(native-chat): a Codex subagent's approval makes its settled parent's Activity row wait

The test pinned the parent row done while a Codex child asked, through a harness
that fed no child records, so it proved nothing about the ask. It now drives the
ask twice through the real host status store: with no child record (the
session's awaitsUser alone) and with the child's own record waiting from
thread/status/changed. Both read waiting with needsAttention while the ask is
open, then done with nothing unread.

* docs(agent-status): a subagent's request reaches the parent row through awaitsUser in every structured lane

The store reference said a Codex child's request still read as the main agent's
blocked and that only the Codex hook lane fed a waiting child. Both structured
lanes stamp the asking child and feed child records, and awaitsUser carries the
request when no record does. The liveness comment goes back to main's: a child's
blocked is a failed task on an older host's legacy rows.

* fix(native-chat): the restart dialog still headlines a subagent's pending approval

The quit snapshot now records the main agent's own state, so a subagent asking
while the main agent worked recorded `working` and the dialog said "Was
mid-reply" where it used to say "Waiting for your approval". The headline now
comes from the snapshot's pending prompt, whoever raised it, with the existing
copy; `state` stays the main agent's own.

* test(orchestration): a subagent's pending approval holds structured mail delivery

Scoping the delivery gate to the main agent's own request left every gate test
green; a subagent's request now has its own case.

* fix(native-chat): a subagent's request is dated by when it was raised, on every client

Since the summary's clock became the main agent's own, nothing dated a wait
that only a subagent's request held: a pre-split client was sent attention with
no clock, where the old host dated it by the subagent's prompt, and a new
client's waiting row fell back to the time it first saw it, so after a reload a
request the user had already read could read unread again.

The session fact is now when someone started being asked: awaitsUserSince, the
oldest pending prompt whoever raised it, and its presence is what awaitsUser
meant. A row waiting on someone else's request takes that as its clock; the
downgrade for a client without the capability dates its attention by it, which
is what the old host published. A cross-version test pinned to the last
pre-split release runs the same journals through that release's projection and
through this one plus the downgrade, and compares the whole summary. The Codex
end-to-end test also reads the host's own status row, and keeps a read ask read
through a later row and a reload.

* test(native-chat): the pre-split parity check compares only the fields the split owns

An additive summary field is safe for old clients, so comparing whole summaries
against the pinned release would redden on one. The wire comment now says how
the downgrade dates attention: the main agent's own oldest ask, else
awaitsUserSince.

* test(runtime): an aged host-held working summary states that nobody is asked

The test built its working summary by overriding the status of a published
approval summary, which still carried awaitsUserSince, so the row correctly
read waiting. It now drops the request as its scenario says.

* fix(native-chat): the chat's subagent block says waiting when the strip does

While a Claude subagent's request was open, the sidebar and the composer strip
read waiting but the subagent block in the chat history a few pixels above
still read "Kicked off 1 subagent working": it shows the journal's roster
state, and the journal records no wait.

The structured chat now hands its transcript the subagents the strip shows
waiting, read from the host's child records through the strip's own row model
and matched by the provider id the roster names each one by. A running entry
the host says is waiting reads waiting in the group row, its entry and its
section head, with the strip's word and the question colour; it reads the
journal's state again as soon as the host stops reporting the wait.

* fix(native-chat): a collapsed subagent group shows a wait beside a failed sibling

A failed sibling took the group row's one alert slot, so a group with a waiting,
a working and a failed child read "1 working +1 failed" and hid the wait; it
now reads "1 working +1 waiting +1 failed". The waiting set keeps its identity
while a child frame changes no wait, so the transcript's subagent rows do not
re-render on every frame, and the test of a wait ending now updates one mounted
row instead of remounting it.

* refactor(claude): one needs-input state on the parent; the asking subagent alone reads waiting

Drop the split of the main agent's own status from a session-wide "someone must
answer" fact: awaitsUserSince, the agent-session.status-awaits-user.v1
capability and its old-client downgrade, and every reader change that only
consumed them (fold, equality, ingest, delivery gate, turn-completion feed,
quit snapshot, resume headline, status clock, status bridge, attention
dispatch) go back to main. The parent row again reads one needs-input state
for a pending request whoever asked, dated as before.

Kept: a request's owner recorded once on its prompt row with full producer
linkage; the asking subagent's own record reads waiting, re-derived on every
update; the chat history's subagent block reads that same state; an answered
subagent request stays in its subagent's group.

A subagent now waits only on a request the user can still answer (its card
open, no answer underway), and the adapter frees it before the host records an
answer or dismissal. So a waiting child record always sits beside the pending
card, and main's fold never reads the parent as waiting on it: no window after
an answer, and no ~3 s wait after a card dismissed by Stop.

* fix(claude): a subagent waits only beside its committed card

A subagent's wait was pushed to the host as soon as its request arrived,
while the request's card row reached the journal at least a microtask later.
So every subagent request published the parent row as waiting before
blocked (the main agent's own fold reads a waiting child that way), and
Activity got an extra unread "waiting" event that main never shows.

The card is now the one record of an open request. The translator records
the asker on the card once (its row's linkage) and counts the card open only
after the sink confirms its rows landed, then publishes the wait; anything
that closes the card (an answer underway, a dismissal handed to the host,
Claude's own withdrawal, the session's end) frees the subagent first. So
every publish that shows a subagent waiting also shows its pending card, and
the parent reads one needs-input state, exactly as on main.

This retires the registry's view of pending requests (unclaimed(), the
asking-child join) and the translator's holdsOpen. The prompt row's linkage
takes one rule: the agent the provider names, else the gated call's owner.

The parent-row proof now runs through the real deferred sink, durable
journal and status feed, publishing as production does, and checks at every
publish that waiting subagents have pending cards and that the parent row
matches a host fed no waits.

* fix(native-chat): a closed sink's dropped writes never read as landed

The sink's written() resolved ok when the sink was closed with writes still
queued, so a subagent's prompt card could count as open with no row in the
journal. written() now reports a close that dropped writes admitted so far
as not landed; drained() and lifecycleBarrier() keep reading a closed sink as
settled.

Tests: a card never opens when its sink closes first; a card Claude withdraws
while the sink holds the cancelled row back closes at once; two subagents
asking at once, and the main agent asking beside a subagent, keep the parent
row as before with each waiting subagent beside its own card; a process that
dies mid-request leaves no subagent waiting.

* fix(claude): a withdrawn subagent request frees its child before its card closes

Main's sink now hands each write to the journal as it is submitted, and an idle journal commits it
and runs the publication at once. Claude's own withdrawal of a subagent's request therefore closed
the card and published the parent row before the child's wait was freed, so one publish showed the
subagent waiting beside no pending card (fg-interrupt replay). The child's wait now also requires the
request to still be open in the registry, and a withdrawal republishes child work before the
journal takes the close.

* refactor(claude): trim subagent request waiting to the common pattern and its essential tests

The chat history no longer marks a subagent block as waiting: the approval card itself carries the
request, and the asking subagent's row in the sidebar and composer strip reads waiting, as before.
NativeChatWaitingSubagentsProvider, native-chat-waiting-subagents.ts and their renderer changes go.

A subagent waits while its request is still open and unanswered in the prompt registry and its card
has landed in the journal. The registry check also covers a withdrawal under backpressure, so the
card list no longer filters pending cancellations itself.

Tests: one integration file replays the captured CLI frames through the real adapter, sink, journal
and status feed (renamed claude-subagent-permission-request.test.ts), with the asking subagent's
state timeline, attribution, nested linkage and a card write that waits for the journal. The
producer-harness waiting test, the redundant prompt-card cases, the harness reducer swap and three
unused captures (deny, interrupt, main agent, failed subagent) are removed.

Settings > Notifications lists each machine (this computer, SSH targets,

* refactor(orchestration): one function for six agent-to-agent sends (#24901)

* refactor(orchestration): send every agent-to-agent message through one sendAgentTurn

The structured mail-pointer lane and the structured worker preamble each carried a copy of
"send, wait out a pending start, read the verdict", and four dispatch-preamble sites typed into
a terminal directly. They now share sendAgentTurn, built from host.send, the host's settlement
waiter and sendTerminalAgentPrompt. Every caller passes delivery 'now', so nothing sends
differently; a source-scan ratchet keeps new direct sends out.

* test(orchestration): the refusal fixture uses a real wire refusal code

* fix(orchestration): derive the send fingerprint inside sendAgentTurn and pair target with turn

A `queue` send was refused by a real host: callers supplied a fingerprint over the body alone
while the host digests body and delivery. sendAgentTurn now builds the envelope with the
composer's own builder (extracted to structured-agent-session-send-mutation), so the fingerprint
is always over exactly the fields sent; `now` sends keep the identical digest. The pointer lane
no longer carries a fingerprint it cannot get right.

sendAgentTurn takes one argument, a union on kind that carries its own target and turn, resolved
by an exhaustive switch; the terminal turn names its purpose (only the dispatch preamble today)
instead of every terminal send inheriting the task lead line. A queued outcome keeps the host's
draft receipt, and both structured callers read outcomes exhaustively with unchanged behaviour.

The boundary test now also fences direct structured host sends, catches optional, bracket and
bound member uses, has a planted-offender self-test, and pins the unmoved terminal mail pointer
and agent-teams tmux senders.

* feat(native-chat): a Claude subagent waiting on a permission prompt reads as waiting (#22634)

* feat(native-chat): a Claude subagent waiting on a permission prompt reads as waiting

A subagent's permission request reaches the parent session's callback naming the
subagent that asked (agent_id) and the tool call it gates (tool_use_id). The
pending request is recorded with the asking agent. On every drain the child-work
producer re-derives which children a pending request blocks and hands that set
to the Claude child decoder, the one owner of each child's live edges: a blocked
child reads waiting on every live edge it reports, and a child that starts or
stops waiting is a live edge of its own. Answering, denying or cancelling the
request returns the child to its prior live state; nothing is stored beyond the
pending requests.

A live task_updated carrying an error now reaches the record as the child's last
message, without an ending or a new state.

The replay test drives a scrubbed capture of the real CLI (foreground allow,
deny, interrupt, background allow, and the main agent's own request) through the
real adapter into the host's child records.

* test(native-chat): a subagent's request names it before its tool call is read

* docs(agent-status): a subagent asking for approval waits in every lane; the parent row keeps the session's own attention

* test(native-chat): hand canUseTool the asking agent without widening the helper's cast

* test(native-chat): an interrupted Claude subagent settles cancelled, not failed

A captured interrupt shows the spawn call's error result ("The user doesn't want
to proceed…") arriving before the subagent's own `task_updated {status: killed}`.
The spawn result ends nothing (the child ends only on its own terminal frame), so
the child stays live until its `killed` status settles it cancelled. A genuine
failure, captured with the subagent on a model that does not exist, sends its
`failed` status before the error result and still ends failed. Both captures now
replay through the real adapter into the host's records.

* fix(native-chat): a Claude subagent's prompt makes the parent row wait, not block

A subagent's pending prompt made the whole session `attention`, which reads as
the main agent's own `blocked` and outranks the fold's waiting arm, so the
parent row read blocked where a CLI Claude parent reads waiting. The main
agent's state now reads only its own pending prompts.

- A Claude prompt row carries the linkage of the agent that raised it: the one
  the permission request names, or the owner of the tool call it gates. The
  same join decides which child reads waiting, so the two cannot disagree.
- The status summary projects the session's own status from root prompts only;
  every other reader (delivery gates, teardown, restart) still asks whether
  anyone is waiting on a human.
- An answer keeps the prompt row's linkage by the journal's own rule: a
  revision that names no producer keeps the row's existing one.
- The child-tool queries gain the prompt's producer, so a prompt row and a
  child record answer "which agent" from the same join.

* test(native-chat): say which ids the permission capture scrubs and which are its own

* fix(native-chat): the status clock dates attention by the session's own asks only

The session's status is now `attention` only for its own pending prompt, so the
clock's fallback to a subagent's ask could no longer be reached, and it read the
journal by a different rule than the status it dates. Both now read root prompts.

The journal also stamps a Codex subagent's prompt with its thread (#22532), so a
Codex child's approval is that child's wait in the Codex lane too. Two tests
written for the earlier rule are updated: a subagent's ask leaves a running
session `working` on its turn's clock, and a Codex child's answered approval
leaves the settled parent's Activity row done with nothing unread.

* fix(native-chat): a completion still says the user is asked when a subagent asks

The turn-completion feed marked a completion `awaitingUser` from the status
summary's `attention`. The status now means the session's own agent is waiting,
so a subagent's pending approval stopped reaching the completion. The projection
now also says whether anyone is waiting on the user, as the delivery gates,
teardown and restart ask it, and the completion reads that.

The waiting-subagent replay answers its prompt with the adapter's current
response shape.

* revert(native-chat): a live Claude task's error stays out of the child's last message

No capture shows a live task_updated carrying an error, and it is unrelated to
a subagent waiting on a permission request; it leaves this PR.

* test(native-chat): settle the Claude session's startup before replaying a subagent's request

A startup frame drained child work during the first await, so answering a
request freed the child even with the answer's own republish removed.

* fix(native-chat): a Claude subagent's prompt row names it as its other rows do

The prompt row stamped only the asking agent's id, so a nested subagent's
request lost the agent that spawned it, its spawn call and its run. It now takes
the linkage the asker's own rows take: the gated tool call's, when that names the
same agent, else the one resolved through the agent's spawn call. The provider's
agent id stays the asker's id.

* fix(native-chat): a subagent's request makes the parent row wait without a child record

The parent row learned that a subagent needed the user only from that
subagent's child record, so a request no record carried (a Codex child the host
never registered, a Claude task past the live cap) left the row working or done
while the approval card sat in the chat.

"Someone in this session must answer" is now one derived session fact. The
projection names two facts instead of a mode flag: the main agent's own status
(attention only for its own request) and structuredAgentSessionAwaitsUser (any
pending prompt). The status summary publishes the second as an optional
awaitsUser, and the shared fold reads it: the main agent's own ask is blocked,
otherwise awaitsUser or a waiting child record makes the row wait. Every caller
picks the fact it means: the completion edge's awaitingUser and the delivery
gate read awaitsUser; the quit snapshot folds the same two inputs the sidebar
does.

* fix(native-chat): a client that predates awaitsUser still reads a subagent's request as attention

A status summary's status is now the main agent's own, so a client built before
the split would read a subagent's request as working (or idle) and fold it with
code that has no awaitsUser input. Clients advertise
agent-session.status-awaits-user.v1; at agentSession.subscribeStatus the host
sends any client that does not the pre-split summary: attention whenever
awaitsUser is set, without the main agent's own tool line, verdict and clock.
The feed and every in-process reader keep the canonical summary. Transitional,
like the turn-item downgrade.

* test(native-chat): a Codex subagent's approval makes its settled parent's Activity row wait

The test pinned the parent row done while a Codex child asked, through a harness
that fed no child records, so it proved nothing about the ask. It now drives the
ask twice through the real host status store: with no child record (the
session's awaitsUser alone) and with the child's own record waiting from
thread/status/changed. Both read waiting with needsAttention while the ask is
open, then done with nothing unread.

* docs(agent-status): a subagent's request reaches the parent row through awaitsUser in every structured lane

The store reference said a Codex child's request still read as the main agent's
blocked and that only the Codex hook lane fed a waiting child. Both structured
lanes stamp the asking child and feed child records, and awaitsUser carries the
request when no record does. The liveness comment goes back to main's: a child's
blocked is a failed task on an older host's legacy rows.

* fix(native-chat): the restart dialog still headlines a subagent's pending approval

The quit snapshot now records the main agent's own state, so a subagent asking
while the main agent worked recorded `working` and the dialog said "Was
mid-reply" where it used to say "Waiting for your approval". The headline now
comes from the snapshot's pending prompt, whoever raised it, with the existing
copy; `state` stays the main agent's own.

* test(orchestration): a subagent's pending approval holds structured mail delivery

Scoping the delivery gate to the main agent's own request left every gate test
green; a subagent's request now has its own case.

* fix(native-chat): a subagent's request is dated by when it was raised, on every client

Since the summary's clock became the main agent's own, nothing dated a wait
that only a subagent's request held: a pre-split client was sent attention with
no clock, where the old host dated it by the subagent's prompt, and a new
client's waiting row fell back to the time it first saw it, so after a reload a
request the user had already read could read unread again.

The session fact is now when someone started being asked: awaitsUserSince, the
oldest pending prompt whoever raised it, and its presence is what awaitsUser
meant. A row waiting on someone else's request takes that as its clock; the
downgrade for a client without the capability dates its attention by it, which
is what the old host published. A cross-version test pinned to the last
pre-split release runs the same journals through that release's projection and
through this one plus the downgrade, and compares the whole summary. The Codex
end-to-end test also reads the host's own status row, and keeps a read ask read
through a later row and a reload.

* test(native-chat): the pre-split parity check compares only the fields the split owns

An additive summary field is safe for old clients, so comparing whole summaries
against the pinned release would redden on one. The wire comment now says how
the downgrade dates attention: the main agent's own oldest ask, else
awaitsUserSince.

* test(runtime): an aged host-held working summary states that nobody is asked

The test built its working summary by overriding the status of a published
approval summary, which still carried awaitsUserSince, so the row correctly
read waiting. It now drops the request as its scenario says.

* fix(native-chat): the chat's subagent block says waiting when the strip does

While a Claude subagent's request was open, the sidebar and the composer strip
read waiting but the subagent block in the chat history a few pixels above
still read "Kicked off 1 subagent working": it shows the journal's roster
state, and the journal records no wait.

The structured chat now hands its transcript the subagents the strip shows
waiting, read from the host's child records through the strip's own row model
and matched by the provider id the roster names each one by. A running entry
the host says is waiting reads waiting in the group row, its entry and its
section head, with the strip's word and the question colour; it reads the
journal's state again as soon as the host stops reporting the wait.

* fix(native-chat): a collapsed subagent group shows a wait beside a failed sibling

A failed sibling took the group row's one alert slot, so a group with a waiting,
a working and a failed child read "1 working +1 failed" and hid the wait; it
now reads "1 working +1 waiting +1 failed". The waiting set keeps its identity
while a child frame changes no wait, so the transcript's subagent rows do not
re-render on every frame, and the test of a wait ending now updates one mounted
row instead of remounting it.

* refactor(claude): one needs-input state on the parent; the asking subagent alone reads waiting

Drop the split of the main agent's own status from a session-wide "someone must
answer" fact: awaitsUserSince, the agent-session.status-awaits-user.v1
capability and its old-client downgrade, and every reader change that only
consumed them (fold, equality, ingest, delivery gate, turn-completion feed,
quit snapshot, resume headline, status clock, status bridge, attention
dispatch) go back to main. The parent row again reads one needs-input state
for a pending request whoever asked, dated as before.

Kept: a request's owner recorded once on its prompt row with full producer
linkage; the asking subagent's own record reads waiting, re-derived on every
update; the chat history's subagent block reads that same state; an answered
subagent request stays in its subagent's group.

A subagent now waits only on a request the user can still answer (its card
open, no answer underway), and the adapter frees it before the host records an
answer or dismissal. So a waiting child record always sits beside the pending
card, and main's fold never reads the parent as waiting on it: no window after
an answer, and no ~3 s wait after a card dismissed by Stop.

* fix(claude): a subagent waits only beside its committed card

A subagent's wait was pushed to the host as soon as its request arrived,
while the request's card row reached the journal at least a microtask later.
So every subagent request published the parent row as waiting before
blocked (the main agent's own fold reads a waiting child that way), and
Activity got an extra unread "waiting" event that main never shows.

that closes the card (an answer underway, a dismissal handed to the host,
Claude's own withdrawal, the session's end) frees the subagent first. So
every publish that shows a subagent waiting also shows its pending card, and
the parent reads one needs-input state, exactly as on main.

This retires the registry's view of pending requests (unclaimed(), the
asking-child join) and the translator's holdsOpen. The prompt row's linkage
takes one rule: the agent the provider names, else the gated call's owner.

The parent-row proof now runs through the real deferred sink, durable

as not landed; drained() and lifecycleBarrier() keep reading a closed sink as

Tests: a card never opens when its sink closes first; a card Claude withdraws
while the sink holds the cancelled row back closes at once; two subagents
asking at once, and the main agent asking beside a subagent, keep the parent
row as before with each waiting subagent beside its own card; a process that
dies mid-request leaves no subagent waiting.

* fix(claude): a withdrawn subagent request frees its child before its card closes

Main's sink now hands each write to the journal as it is submitted, and an idle journal commits it
and runs the publication at once. Claude's own withdrawal of a subagent's request therefore closed
the card and published the parent row before the child's wait was freed, so one publish showed the

* test(claude): pin the parent row's dating when a subagent asked first, and narrow the oracle's claim

* Turn desktop notifications on or off per machine (#24518)

* feat(notifications): turn desktop notifications on or off per machine

Settings > Notifications lists each machine (this computer, SSH targets,
paired Orca servers) with a switch. Muted machines are stored as an
opt-out list so a newly added machine still notifies. Both notification
senders now name the machine a workspace runs on, and main skips the
desktop banner for a muted one; phone push is unchanged.

* fix(notifications): preserve phone alerts and honor machine mutes

* fix(notifications): clarify machine switches affect only this computer

* fix: distinguish unavailable account metadata from absence

* fix(accounts): resolve registered profile UUIDs consistently

* Replace agentArgsOverride with unified removeAgentArgs approach (#25091)

Consolidate override detection and removal into removeAgentArgs. Previously
catalogs used agentArgsOverride to detect conflicts and removeAgentArgs to
strip them; now removeAgentArgs handles both by returning stripped tokens.
This eliminates redundancy and makes the intent clearer.

Enhance removeAgentArgOption with optional value filtering to support
selective removal for complex cases like Codex config overrides.

* Reuse the ancestor path while building mobile agent rows (#24539)

Preserve traversal order and cycle guards using one call-local path Set rather than a copy at every depth.

* Release waiting terminal output when a mobile subscription fails to start (#24547)

Dispose the failed subscription record’s existing terminal backlog before rethrowing its original start error.

* Avoid cloning terminal agent owners twice in relay listings (#24713)

Capture the existing host-age expression at its original time, then use one call-local fresh owner clone for the length check and unchanged published owner field.

* Reuse prepared statements for internal worker checks (#24573)

* Reuse prepared statements across remaining Dispatch reads

Use the existing schema-pinned complete Dispatch column list in five remaining read modules, enabling the existing bounded statement cache without caching results.

* Reuse prepared statements for internal worker checks

Use the existing complete Dispatch projection only for named-field internal consumers; preserve original wildcard reads for every returned failure snapshot.

* Prepare the Activity search query once per filtered list (#24701)

Lazily reuse a call-local search predicate inside the existing filter, using unchanged byte gates and thread text cache.

* Avoid rescanning shared chunks in the plain Node build guard (#24717)

Reuse a successful unchanged chunk-code verdict within one synchronous writeBundle invocation, while preserving traversal and current-code reads.

* Select the latest stable release tag in one pass (#24786)

Replace filter/sort/last selection with one traversal using the unchanged stable-tag regex and numeric comparator; update on equality to preserve the original last spelling. Both actual callers own private plain arrays from Git stdout.

* Avoid Resource Manager renders when terminal removal leaves its inventory unchanged (#24806)

Reuse the private React state object only when the existing single/bulk removal helper returns its identical inventory; keep every lifecycle revision, tombstone, known-ID write and helper invocation in its original order.

* Cancel pending cursor updates when a terminal closes (#24566)

Reuse the existing pane frame tracker to cancel owned deferred focus-class updates during existing cleanup, with disposed guards against late or reentrant delivery.

* Cancel terminal preview fit frames when the preview closes (#24712)

Reuse the existing frame tracker inside the box-fit owner, suppress scheduling after disposal and cancel pending frames at the start of the existing effect cleanup.

* Skip new mobile toast work after feedback owner cleanup (#24759)

Reuse the existing mobile mounted-ref lifecycle pattern at toast presentation entry, preserving admitted clipboard outcomes and every live animation/sequence/timer operation.

* Release terminal side effects after they have been delivered (#24548)

Clear consumed queue slots after successful apply or overflow carry; preserve backing identity across reentrant callbacks and report actual retained slots.

* Release relay handshake timers when a host connection leaves (#24554)

Reuse the existing first-frame finish pattern to remove stage-owned timer/message/close callbacks on receipt, timeout or close; check OPEN after successful async assignment verification.

* Avoid restarting error timers on closed mobile relay links (#24567)

Check the existing irreversible closed flag before scheduling the existing missing-close fallback timer.

* Avoid restarting error timers after mobile relay pairing closes (#24568)

Check the existing pairing owner closed flag before allocating its missing-close fallback alarm.

* Delete unreturned clipboard cache files after a failed write (#24599)

Reuse existing provider-copy best-effort deletion for a newly created clipboard cache file whose write fails before its URI reaches the caller.

* Skip new legacy file inventories after mobile search cleanup (#24792)

Reuse the existing mobile mounted-ref pattern only at legacy fallback entry after completed passive cleanup; preserve admitted work and all live search/authority/cache paths. Correct only the strict fully-unmounted inventory scenario and its sole golden.

* Discard completed AI Vault cancellation IDs in the relay worker (#24820)

Use the relay child's existing pending Set to ignore cancellation IDs after completion, matching its desktop sibling; preserve admitted active/queued cancellation and the bundled private sender's complete replies, errors and ownership.

* Release completed updater setup timers and callbacks (#24920)

Cancel completed deferred updater fallbacks in finally, clear only their exact pending callback, and drop the captured timer before the original fallback guard runs; preserve destroyed admission, successor ownership and updater/quit callbacks.

* Check daemon idle state without building discarded terminal inventories (#24749)

* Check daemon idle state without building discarded terminal inventories

Replace the private idle predicate full public inventory with a host-local full pass that still reads every Session liveness getter in original order.

* Remove overwritten daemon test mock assignment

* Preserve the registered account ID when selecting UUID variants

* fix(updater): keep macOS Orca open when background instances block updates (#24952)

* fix(updater): guard macOS installs against running app instances

* fix(updater): match native app blockers and preserve quit lifecycle

* fix(updater): keep ordinary macOS quit on Squirrel's install-on-exit path

Converting every quit with a staged update into quitAndInstall made Cmd+Q
relaunch Orca, refused the quit when background instances existed, and
hijacked app.relaunch()+app.quit() restart flows (profile switch, admin
restart) into an update install racing the relaunched old app. Only
Update & Restart runs the running-instance preflight now; the
quit-without-install allowance is no longer reachable and is removed.

* fix(updater): preserve quit intent through macOS staging

* test(native-chat): explicitly model legacy published tab ownership

* Skip store notifications when refreshed work items are unchanged (#24530)

An identical forced refresh previously returned an empty Zustand patch, creating a new root state and notifying every subscriber. It now returns the current state after renewing the existing freshness timestamp. Real row or metadata changes still publish once.

* Read project activity once while sorting the sidebar (#24549)

Reuse the existing pure recent rank once per actual entry tuple within each synchronous sort; discard the lookup after sorting.

* Skip impossible link and tag matches in docs search results (#24646)

* Skip impossible HTML matches when formatting docs search results

After the existing link-removal phase, skip the unchanged HTML regex only when the current string has no closing delimiter.

* Skip impossible link and tag matches in docs search results

Skip the five unchanged link regexes when their protected-code input lacks ]; skip the unchanged HTML regex when its post-link input lacks >.

* Decode complete transcript lines without copying their bytes (#24546)

Decode each single owned Buffer synchronously; preserve concatenation for multipart records and remove a redundant tail array copy.

* Clear unused speech worker timers after errors and exit (#24924)

Call the existing idle timer cleanup when private current-worker state is cleared; keep current-worker guards, transcript/error order, deliberate warmth and stop deadline unchanged.

* Reuse documentation search excerpts during result navigation (#24574)

Memoize the existing pure excerpt renderer by complete raw text for the current result array, retaining original rendering as a miss fallback.

* Append subagent handoffs without recopying their message list (#24672)

Append each message reference to its private call-local scope list; retain the final merge and existing ordering.

* Cancel plugin retry timers when their fetch is replaced (#24700)

Reuse the existing timer clear block immediately after the fetch generation advances; preserve live retries and all state publications.

* Avoid rebuilding visible file paths for single-row selection (#24743)

Skip the visible path array only for keyboard replacement selection; the existing replacement branch never reads that order.

* Reuse prepared reads while searching saved agent conversations (#24535)

Use schema-complete session columns to enable the existing bounded statement cache without caching result rows.

* Reuse discovered mobile chunks during static traversal (#24774)

Iterate the existing live visited Set in FIFO discovery order instead of maintaining a second shifted queue; both actual callers own untouched esbuild JSON metadata.

* Skip unused image-size calculations in mobile web browser requests (#24941)

Use the existing mobile density budget only for mobile view; pass the existing constant to the existing assembler for web/default mode, where that argument is discarded. No cache, policy, request or native path changes.

* Skip diff analysis after a result has been discarded (#24711)

Move the unchanged pure render-limit calculation after both existing generation and section-token rejection fences.

* Skip late browser grab toasts after their surface closes (#24727)

Reuse the existing mounted-owner ref at the toast presentation entry while preserving all admitted extraction/screenshot and clipboard completion.

* Classify native chat waiting messages once (#24771)

Use the existing native filter traversal to populate a fresh waiting array, keeping the original predicate, policy, projection and output ordering while classifying each actual private slot once.

* Skip discarded Kanban pruning for an empty selection (#24782)

Guard only the existing open pruning branch when both its private selected Set and nullable anchor are empty; retain all original pre-guard projections and nonempty/anchor-only/public-helper behavior.

* Index discovered test files once during shard selection validation (#24532)

Verified selection plans previously validated each selected filename with a scan of all discovered files. One per-call Set now handles membership checks. Exact source/discovery checks, nonempty selection, fallback to all tests, shard balancing and manifests remain intact.

* test(terminal): restore the live fish fixture prerequisites (#24947)

A restored pane waits for the initial status replay before subscribing to
PTY output. This fixture never settled that replay, so fish printed its

Read OpenCode output format from active final-argv options before -- so literal prompt arguments cannot select the JSON finalizer.

Fresh exact-source controls reproduce nine failures before; 139 related checks pass after, including primary/fallback delays, deadline boundaries, cancellation, parser metadata, and SSH lanes. Node typecheck and strict changed-file lint pass.

* test(jcode): measure the gate against the synchronous path, not the clock

The absolute 1s bound was the flake CI shard 3/8 hit: it is tight enough to catch
a synchronous gate on an idle laptop and too tight on a loaded runner. Measuring
the same POST both ways on the same machine makes the claim a ratio, which is what
the test is actually about. Mutation-checked: a synchronous gate reads 6120ms
against a 1517ms observer.

* test(jcode): drop the wall-clock gate assertion

* fix(jcode): address CodeRabbit review on #22539

- Windows posted no payload at all: the shared builder reads `payload@-` from
  stdin, which the gate has already drained and observer hooks never receive, so
  every Windows event was dropped. Write the env var to a temp file and pipe it.
- The daemon pre-warm never fired for daemon-host spawns, which is the default
  local path; it now runs there too, and from the final env so the daemon gets the
  hook port and token.
- A failed runtime-dir mkdir took down every local terminal, jcode or not.
- removeJcodeManagedHooks matched the raw line, so a user hook whose comment
  mentioned the managed script was deleted; matching on Windows never worked.
- A managed entry left by a copied home or a platform switch is now repointed
  instead of being reported as user-owned forever.
- The OSC colour skip only checked launchAgent, so a command- or telemetry-named
  jcode pane still leaked the reply into its composer.
- `['hooks']` and a commented scalar are recognised, instead of appending a
  second [hooks] table that makes jcode reject the whole config.
- A failed tool's error is marked as tool output rather than agent prose.
- The vault keeps a session's stored name, counts its tokens, and skips
  background_task and [Scheduled task] turns.

* fix(jcode): read the journal once per turn, key prompts by byte offset

The jcode prompt reader ran a synchronous bounded file scan plus a JSON
parse on every hook event. jcode blocks on pre_tool, so a turn that ran
four tools charged the user eight scans of latency it did not need — the
prompt cannot change inside a turn.

- Cache the journal read per pane, refreshed on the turn boundary that
  can change it. The cache holds the whole evidence record, since
  hasExplicitUserPrompt needs the transcript-evidence flag and not just
  the text, and it joins the existing pane-scoped lifecycle (close,
  rename, reset) rather than living in a module singleton.
- Key a journal prompt by its absolute byte offset instead of its
  region-local line index. The backward scan windows the file from EOF,
  so appending shifted every boundary and reminted the key for a prompt
  that never moved; a repeated turn_end then slipped past the same-hash
  dedupe as a second done event with duplicate telemetry.
- Pin the platform in the daemon pre-warm tests. The pre-warm is a no-op
  off POSIX, so the dedupe and retry cases would have passed vacuously
  on a Windows runner.

* fix(jcode): quote the managed hook path, drop tools from patch prompts

Three fixes, all on paths this PR could not exercise locally.

The managed hook command was stored as a bare path. jcode tokenizes that
string shell-style before exec'ing it directly (parse_hook_command,
crates/jcode-terminal-launch/src/lib.rs): unquoted whitespace splits, and
every unquoted backslash is consumed as an escape. So on Windows
`C:\Users\me\.orca\agent-hooks\jcode-hook.cmd` reached exec as
`C:Usersme.orcaagent-hooksjcode-hook.cmd` and no hook fired at all, and a
POSIX home with a space split into two arguments. Store the path
single-quoted (verbatim, backslashes included), falling back to double
quotes for a path containing a single quote. Existing bare entries are
already repointed by the stale-key path, and getStatus accepts both forms
so the repair is not reported as a user-owned hook. The quoting helper was
previously dead code that only tests called; the three production sites
now use it. isJcodeManagedCommand also normalizes separators, since a
`/`-only needle never matched a Windows entry.

Commit-message generation feeds a staged patch to `jcode run` as the
prompt — attacker-influenced text — while jcode's default profile exposes
shell, read, write, and MCP. Pass `--tool-profile none`, which resolves to
an empty allowed-tool set in jcode's config (base_allowed_tools), matching
the read-only posture claude (plan) and codex (read-only) already take.

docs/reference/jcode-hook-events.md was never actually in this PR: the
repo ignores docs/** and tracks reference docs by allow-list only, so the
captured-payload evidence four source comments point at was silently
dropped. Allow-list it.

* test(jcode): pin the tool-profile flag in the generation plan too

Co-authored-by: czzczz <chanzrz_zbf@foxmail.com>

* fix(text-generation): refuse an oversized argv prompt on Linux too

The pre-spawn size guard only ran on Windows. Linux caps a single argv
entry at MAX_ARG_STRLEN (32 pages, 128 KiB on a 4-KiB-page host) and
execve fails with E2BIG past it, so an agent that delivers the whole
prompt as one argument — jcode, and the other argv-delivery agents —
failed on a large staged diff with an error the user could not act on.

The cap is per-argument and in bytes, which is why it is not the Windows
line budget: 40k chars trips Windows and is nowhere near the Linux limit,
so folding them together would have refused prompts Linux runs fine.

* fix(jcode): register in main's remote-installer guard, drop our duplicate

Rebasing onto 853 commits of main surfaced two things the earlier branch
had hidden.

main already owns a guard for the issue-#7253 bug class
(`remote-hook-service-registry-coverage.test.ts`). This branch had added a
second, near-identical one — a parallel implementation of a test that
already existed, which is what AGENTS.md's reuse rule is about. Deleted
ours and registered jcode in main's, which is the one that has kept pace
with every agent added since.

Also fixes a missing separator in the mobile icon map. `pnpm tc` does not
cover `mobile/`, so only the session-route closure suite caught it.

Co-authored-by: czzczz <chanzrz_zbf@foxmail.com>

* fix(jcode): decompose the four files jcode pushed over max-lines

Adding an agent tipped four modules past their line budget. AGENTS.md
forbids a `max-lines` disable or a per-file bump, so each is split on a
real seam rather than silenced:

- agent-catalog.tsx keeps `AgentIcon`, which 70+ files import, and the
  rows move out. The rows alone exceed the 300-line budget a `.ts` file
  gets, so they follow the primary/secondary split this repo already uses
  for commit-message agent specs.
- getAgentResumeArgv -> agent-resume-argv.ts, re-exported so the 18 call
  sites keep one import path.
- isDiscoverableSessionFile/pathSegments -> session-file-discovery.ts.
- remoteCodexSources -> remote-session-scanner-codex-sources.ts; Codex is
  the one remote agent with two CODEX_HOME roots.

Also:
- Records the readiness-census baseline jcode now needs. main added that
  gate while this branch was out; the fixture is the recorded 74-case
  matrix, not a hand-written one.
- Restores two entries a rebase resolution silently dropped from
  config/tsconfig.cli.json (gitlab/project-ref-parser,
  startup/shell-path-probe). Nothing to do with jcode; losing them was a
  conflict-resolution mistake on this branch.

* feat(native-chat): open structured chats on the paired Orca server that owns the workspace (#24205)

* fix(native-chat): a host admits structured sessions by client capability, not its own chat setting

A host's experimentalStructuredNativeChat decided whether any paired client could reach
agentSession.* at all, and whether session.tabs.* showed it structured tabs. That setting is the
host user's own launch preference: whether a new agent opens as a chat or a terminal is decided by
whoever launches it. Using it as admission control meant a client whose own preference was
"structured chat" was refused on a host whose preference was "terminal", and chats opened while
the setting was on were withheld from mobile once it was turned off.

The gate now asks one thing: did the client advertise agent-session.structured.v1 (in-process
callers negotiate nothing and are always admitted). Tab projection and restore follow the same
rule. With the setting no longer gating anything, the separate cleanup gate (close, cancel,
unsubscribe, release), which existed only so those kept working after the setting was switched
off, is identical to the main gate and is folded into it. The settings listener that republished
tabs when the setting changed is removed, since projection no longer depends on it.

The host setting still picks the default for launches that start on the host itself
(agent.launch from mobile, orchestration worker-start).

* fix(native-chat): the desktop declares structured chat support to paired hosts

The desktop renderer advertised agent-session.structured.v1 (and the Claude, turn-item and
background-task capabilities that go with it) to its own main process but not to a paired Orca
server. The server therefore refused every agentSession.* call from the desktop and stripped
structured chat tabs out of the tab list it published to it, so a structured chat running on a
paired server never appeared on the desktop, even though the renderer already mirrors a host's
agent-session tabs and drives each one against the server that owns its workspace.

The same renderer reads structured chats on either host, so the remote Electron list now carries
the same structured-session capabilities as the local one, and the capability test pins that
nothing is advertised only locally.

* feat(native-chat): open structured chats on the paired server that owns the workspace

With the structured-chat default on, an agent launched in a workspace that lives on a paired Orca
server always opened as a terminal (or the terminal-backed chat view). Three things kept it off
the structured path: the launch check refused every host but this machine, a remote workspace was
handed to the host-published terminal path before the structured route was even considered, and
the structured launch pipeline sent create and every follow-up call to this machine's runtime.

A workspace's owning runtime is fixed, so the pipeline now derives it from the workspace instead
of assuming this machine (structured-agent-session-owner.ts, the same derivation the chat pane
already uses to read a session). The launch intent carries that target; the pre-create support
check, create, the publication check and fence read, the launch prompt send, held option picks,
the "focus this chat" marker, the placeholder tab's host, and tab close/purge all use it.

The launch check now accepts a paired server and asks that server's own capabilities (read from
the status the client already cached for it) rather than this machine's. An SSH workspace stays
terminal-backed: no Orca runtime runs there. The host still answers createSupport before
anything is created, so an older server that refuses shows the failure in the chat tab.

A chat the user closed before its create landed is now also retired on the paired server when it
publishes, as the local sync already does. Orchestration workers placed on another runtime are
unchanged: federation creates terminal agents only.

* fix(native-chat): negotiate client-chosen launch mode so released phones and old servers keep terminals

Hosts advertise agent-session.structured.client-launch-mode.v1: they admit
structured sessions by client capability alone. A remote client that does
not advertise it (phones released before agent.launch) asks createSupport
to pick the launch mode, so the host keeps answering that with its own
setting, exactly as before. Cleanup methods keep their own named gate so a
future admission condition cannot make close or cancel refusable.

* refactor(runtime): keep the Electron client capability list in its own module

protocol-version.ts is at its line budget; the list is what the desktop
advertises to paired hosts, not the host's own contract.

* fix(native-chat): the desktop declares it picks each launch mode itself

Paired hosts and the desktop's own main process then answer createSupport
by the workspace rather than by their own chat setting.

* fix(native-chat): pin each structured chat to the host it was launched on

- Route: a paired server opens a chat only when it advertises the
  client-chosen launch mode; an older server keeps its terminal. Its
  capabilities come from the store's host status, not the compatibility
  cache that is empty after boot or reconnect.
- A launch command override is this machine's: the route applies it only
  locally, and a host's createSupport refuses on its own override.
- The owning host is resolved once, from the same value the route used,
  and carried on the launch intent, its persisted record (legacy records
  load as local), the provisional tab and every mirrored chat tab. Close,
  purge, retry and reload read it instead of re-deriving it from a
  worktree id two hosts can share; an owner that cannot be named refuses.
- Cancellation tombstones record their host: only that host's
  authoritative inventory retires one, restored cleanup closes it there,
  and a paired host's tombstone expires after 30 days if it never answers.
- A paired server's frame settles launches it published, as the local
  inventory already does for this machine.

* fix(native-chat): a paired server that declines a chat opens its terminal instead

createSupport only reads, so both of its non-answers are settled before
anything is created:
- A paired server that answers it cannot run the chat (a WSL repo, a
  Claude account mismatch, its own launch command override) closes the
  chat tab and opens the terminal the route would have chosen, with a
  notice saying why. This machine's own decline stays a failed chat.
- A host that could not be asked closes the chat tab and leaves one
  failure toast, instead of a lingering "could not confirm" chat.

* test(native-chat): a provisional chat carries its launch's host and hands pre-create failures on

* chore(native-chat): justify the two type assertions this change's lines touch

* test(native-chat): state why each staged test fixture is cast

* fix(native-chat): chats that already exist keep showing whatever the chat setting says

The structured chat setting decides only what new agents open as. With it
off, this machine's structured chats used to be hidden while the host,
which no longer reads the setting, still reported them to the workspace
activation gate, so a workspace holding only a chat opened empty. The
local chat mirror and its startup restore now run whatever the setting
says, the continue-after-restart offer follows the chats that exist, and
the setting's copy says it applies to new agents.

* fix(native-chat): the browser client keeps its host terminal on paired servers

A browser client whose own preferences turn structured chat on took the
structured route for every paired-server workspace, but its handshake
never says it reads structured sessions, so the server refused the chat
and the user got a failed chat tab where a host terminal used to open.
The route for a paired host now also asks what this client advertises to
it: the desktop's list does, the browser client's does not. Its handshake
list is now a named constant the route reads, so the two cannot drift.

The chat setting's copy now says it runs on paired Orca servers too;
WSL and SSH hosts still use terminal chat.

* fix(native-chat): a retried launch a paired server declines opens its terminal too

A launch restored after a reload settles only through its Retry, so a
declining paired server left a failed chat there while a first launch got
the server's terminal and a notice. The chat's Retry now hands the same
pre-create failures to the same replacement, carrying the prompt the
launch had staged.

* refactor(native-chat): a paired host's cancelled-chat record ends on its 30-day TTL

The paired census re-read a host's whole inventory after every
authoritative frame to retire tombstones, and a tombstone restored after
a reload needed a second such frame, so in practice it retired nothing.
A tombstone guards a random session id and is inert once stale; the chat
is already closed on its host whenever a frame shows it. The census, its
trigger in the mirror layer and its cleanup are removed; the owner-scoped
tombstones, close-on-sight, the TTL and publication marking from frames
stay.

* fix(native-chat): a chat's pane and status read from the host recorded on its tab

The chat pane and its sidebar status still derived the host from the
workspace id, which two hosts can share; a paired chat in a non-active
same-id workspace was read from this machine. Both now read the owner
stamped on the tab, as close, purge and publication already do.

* fix(native-chat): "Resume in chat" follows the terminal resume's host rule

Agent Session History offered "Resume in chat" for a conversation
recorded on this machine into a paired server's workspace, where its
transcript does not exist. A chat now resumes a conversation only on the
host that recorded it, as the terminal resume does, and that host is the
one asked whether it can resume history.

* fix(native-chat): the chat setting says older paired servers keep terminal chat

* test(native-chat): pin that a host advertises the client-chosen launch mode

* fix(native-chat): mirror this machine's chats only where it holds them

Round 1 ran the local chat mirror for everyone so existing chats show
whatever the setting says. That gave every desktop a permanent
session-tabs listener, which turns on the runtime's phone replication
paths, plus two full session-tab censuses at startup, and made the
browser client mirror its remote host a second time.

The runtime now says whether it holds structured chats: its structured
host is built only when saved chats were restored at startup or a client
created one here, and it announces the moment one is built. The mirror,
the startup restore and the continue-after-restart offer run only when
the setting launches chats or the host holds some, and never in the
browser client. A chat a paired client creates here with the setting off
still appears at once. The chat behaviour settings show wherever chats
exist, and the setting's copy says it picks what new agents open as. The
toggle-off teardown this made dead is removed.

* test(native-chat): route a paired-server launch over the capability lists both sides really advertise

* test(native-chat): record install listeners without a cast

* fix(native-chat): a paired server admits a chat before any of it exists here

The desktop opened a paired server's chat tab, launch record, queued
prompt and focus intent before asking the server, so a "no" needed a
replacement that undid and redid all of it, and every piece it missed
was a bug: the workspace deselected, the caller told "failed" while a
terminal ran its prompt, the caller's arguments and other queued prompts
lost, and a create whose reply was lost treated as never sent.

A paired launch now asks the server first and commits nothing until it
answers. Admitted opens the chat as before. Declined runs the caller's
own launch as the server's terminal, with the existing notice (a resume
fails instead, having no terminal equivalent). Unreachable opens nothing
and names the server in one toast. The new-tab launcher reports the
host's surface for paired workspaces, as it did before paired chats,
with the prompt delivery of whichever surface got the prompt. The
replacement and its error classes are gone, and the probe inside a
launch is back to its old meaning: a "no" is a failed chat with Retry,
and no answer leaves "Could not confirm" with Retry and the prompt kept,
here as on this machine.

* fix(native-chat): mirror this machine's chats only once it holds one, not once its host is built

Session history, resume preparation, terminal resume commands and replay-safe phone launches all
build the structured host for users who never had a chat, which turned on the chat mirror and the
structured-only settings rows until the next restart. The signal is now derived from the host's
records (or a records file still owed its import) and pushed when the first chat is restored or
created. A throwing listener no longer fails the install that fired it.

* fix(native-chat): a fork's reveal never seeds a terminal beside the surface the launcher opens

Forking into a paired-server workspace revealed it as if nothing would open there, so the reveal
created a blank host terminal beside the forked chat (and beside a forked agent terminal on main).
The launcher always opens the fork's surface itself, so the reveal now says so for every surface,
as the fix-checks launch already does.

* fix(native-chat): a declined direct launch keeps the caller's CLI args; an unreachable resume toasts once

When a paired server declines a "Fix checks" chat in a new workspace, the terminal that opens
instead now carries the recipe's saved CLI arguments, launch platform and launch source, as the
terminal route did. "Resume in chat" to a server that cannot be reached showed the admission's
"Could not reach" toast and the vault's generic one; the admission marks its failure notified and
the vault adds nothing.

* fix(native-chat): a declined background create opens its terminal without switching workspaces

Since #23974 a worktree create the user moved away from must not pull them onto the new
workspace. When a paired server declined that create's chat, the fallback terminal opened as a new
agent tab, whose host create selects the workspace. The create now opens its own agent terminal the
way main's background branch does: in place from the request's startup plan (so its CLI args carry),
without selecting the workspace. A create the user is still watching keeps the new-tab fallback.

* test(native-chat): name the launch's host in main's new outbox fence test

Main's new staging-failure test calls settleStructuredAgentLaunchPrompt without the target this PR
made required; it is a local launch, as in the sibling tests.

* fix(native-chat): a paired server's new chat shows no model until the server reports the one it started

A chat on a paired server starts with the server's saved model and options, but the picker showed
this desktop's saved selection (or the catalog default) until the server reported a model, and a
pick made in that window was remembered on the server under that guessed model. A paired launch
now carries no desktop seed, and until the server reports its model the picker names no model and
takes no picks. Local chats are unchanged.

* test(native-chat): seed the paired repo without a cast

The repo literal already satisfies Repo, so the changed-lines cast gate has nothing to excuse.

* feat(native-chat): createSupport reports the saved selection a new chat on this host starts with

A chat on a paired server starts with the server's saved model and options, which the desktop could
not read, so its picker showed a guess. createSupport's answer, which the desktop already waits for
before a paired launch, now also carries that seed as a new optional field (older clients ignore it).
Create and createSupport read it through one resolver so they cannot drift.

* fix(native-chat): a paired server's new chat shows the selection the server will start it with

The paired server now names its saved model and options in the admission answer the desktop
already waits for. That seed goes into the launch intent and its persisted record, so the picker
shows the server's model at once, stays pickable like a local chat, and remembers picks on the
server under that model; a reload shows the same. The locked picker remains only for a server too
old to name a seed.

Also moves host admission and launch-outcome tracking into their own modules: the latest main
merge left structured-agent-session-launch.ts over the max-lines limit.

* test(native-chat): expect the launch intent's new seed argument in exact-call assertions

* refactor(protocol): move the Electron remote client capability list into its own module

Merging main left protocol-version.ts one line over the max-lines limit on this branch. The list of
capabilities the desktop advertises to a paired host moves, unchanged, into
electron-remote-runtime-client-capabilities.ts, the module the next PR in the stack already uses
for it; importers point there.

* fix(native-chat): a paired chat with no saved server model is pickable; Retry shows the server's current seed

A server whose user never saved a chat model sends no seed, and the desktop showed a locked,
model-only picker for it, although that is the common case: no server that can admit a paired chat
predates the seed field. Such a chat now behaves like a local chat with no saved model: the CLI
default, pickable. The lock and its snapshot helper are gone.

Retry kept the first admission's seed while the create probe, which already runs on every attempt,
reported the server's current one and dropped it. The probe's seed now replaces a paired launch's
seed and the picker's, so a retried chat shows what its create will run.

* test(cross-version): stub the launch seed resolver createSupport now reads

* test(protocol): pin the desktop capability divergence against what a paired server receives

Every paired transport sends the shared remote base plus the Electron list, so the
divergence test now compares that union with the renderer's local list instead of
the declared Electron list. A capability added only to the shared base can no
longer slip past it. The two base-only capabilities it surfaced are recorded:
skills.install-result.v2 has no local caller; the authoritative-inventory label is
read by the local tabs sync but dropped by main, and is marked unsettled.

The turn-item and both background-task-stop capabilities were already sent through
the shared base, so the Electron list no longer repeats them. The wire set is
unchanged; this PR's real change on the wire is structured.v1, the Claude
structured capability and the client launch-mode capability.

* fix(native-chat): the desktop tells its own host it picks each launch mode, so retrying an existing chat works with the setting off

* docs(native-chat): name the real exit for the released-phone createSupport rule

* fix(native-chat): the route reads the capabilities a paired host actually receives

The renderer decided whether a paired host would admit a chat from the desktop's Electron list, but
every desktop transport sends that list plus the shared remote base. They agreed only because the
route's checks happened to sit in both. The route input is now built with the same
remoteRuntimeClientCapabilities the transports use (the browser client already sends its list as is),
a…

* ci: run the cross-version tests when the chat send builders or the RPC request path change (#25061)

The selector skipped the cross-version wire job for #24901, which changed the
shared agent-send path, the structured send envelope builders, and orchestration
RPC code. Route the send payload/fingerprint builders, src/main/runtime/orchestration/,
and the orchestration RPC methods to the job, and pin each rule in a test.

The agent-session suites now build their send through the shared outbox

orchestration rules are dropped; the dispatcher-path files every suite
request runs through are selected instead.

* feat(codex): tell Windows users once that Codex in Orca now shares ~/.codex (#24916)

* feat(codex): tell Windows users once what stays behind when Codex moves onto ~/.codex

When Windows' system-default Codex first runs on ~/.codex (launch prep or
the usage poll), main decides once whether Orca's managed home was ever
used and which MCP servers lived only there, and persists that in UI
state. The renderer shows one dismissible toast when a Codex terminal
exists, after the server-isolation notice rather than on top of it, and
clears the notice when shown.

The "kept only in the managed home" MCP rule is extracted into
isRuntimeOnlyMcpServer, which the config mirror merge now uses too, so
the notice names exactly the servers the mirror would have kept.

* fix(codex): stop counting Orca's own config.toml as use of the old Codex home

Orca's hook install writes that home's config.toml on every startup, so its
presence was true for nearly every Windows user with Codex. The home now
counts as used only with recorded sessions or an MCP server of its own.
Resolver tests keep one case per input source.

* refactor(codex): ask main for the shared-settings notice instead of persisting it

The persisted missing/object/null field, written from launch prep and the
usage poll, becomes a plain codexSharedSettingsNoticeSeen flag mirroring
codexTerminalServerIsolationNoticeSeen. When a Codex terminal first appears
and the flag is unset, the renderer asks codexConfigSync:sharedSettingsNotice
once; main answers read-only (Windows, system default on ~/.codex, managed
home path without mkdir) and maps any read error to null.

Runtime-home routing, launch and the test harness return to main's code.
The notice no longer waits for the server-isolation toast; they may stack.
The Codex-terminal watch moves to codex-terminal-presence.ts.

* refactor(codex): watch for the first Codex terminal in one place for both notices

The server-isolation notice now passes its due check to
whenCodexTerminalAppears instead of keeping its own copy of the presence
scan, input filter and subscription loop. Its behaviour and tests are
unchanged.

* docs(codex): trim isRuntimeOnlyMcpServer's comment to why it is shared

* refactor(codex): keep McpServerTomlOwnership private to its module

* test(codex): cover the shared-settings notice channel without type assertions

Handlers are looked up by channel now that two are registered, so the
status tests no longer depend on registration order.

* refactor(codex): show the Windows shared-settings notice without asking main

Every way of detecting who relied on Orca's old Codex folder had false
positives, so the renderer now shows one static toast on Windows the first
time a Codex terminal exists. This drops the main-process resolver, its IPC
channel, preload line, web stub and shared type, and the MCP-names variant
of the description.

* refactor(codex): restore the MCP server ownership helpers to main's shape

The static notice no longer reads MCP servers, so the shared
isRuntimeOnlyMcpServer extraction has no second caller.

* refactor(codex): let each notice decide when it is due, so the Codex watcher only watches

The isolation notice now selects its due predicate and starts the watcher only while due, so whenCodexTerminalAppears no longer takes an isDue or re-checks hydration and settings. The shared-settings notice uses isLocalWindowsDesktopClient, its test stubs the user agent instead of mocking pane-helpers, and the hydration safeguard it relies on is now tested on the UI slice itself.

* test(codex): drive the Codex notices through a reactive store, and drop a redundant hydration gate

The server-isolation notice now reads "is it due" through a store selector, but its test
mocked the store without re-rendering, so a due change after mount (persisted UI loading,
the setting turning off) was never exercised. The notice tests now share one harness backed
by a real zustand store, the shared watcher gets its own test, and both notices cover the
seen flag loading after mount.

persistedUIReady is dropped from isNoticeDue: the seen flag defaults to true and only
hydration clears it, in the same update that sets persistedUIReady. Both notices now gate
the same way.

* fix(codex): keep the shared-settings toast until dismissed, and shorten it

It is marked seen before it shows, so a 15s auto-close could lose it for good while the user
is typing in the Codex terminal that triggered it. Every other one-shot notice that marks
itself seen on show stays until dismissed; this now does too.

The text drops the sentence that repeated the title and keeps only what to expect and do.

* fix(codex): keep Orca-only MCP servers when refreshing the retained shared home (#24983)

* fix(codex): keep Orca-only MCP servers when refreshing the retained shared home

The refresh for panes that outlive an update treated the old shared
home's whole MCP root as owned by ~/.codex, so it deleted servers the
user had added from an Orca terminal, which existed only there. Read the
home's settings baseline instead, as the normal mirror does: drop only
servers the last mirror copied from ~/.codex. No baseline keeps the old
behaviour; an unreadable one skips the refresh. The baseline is not
advanced, keeping the refresh one-way.

* A resent chat message gets its recorded answer, never an early refusal or a made-up record (#25158)

* fix(native-chat): a resent send id gets its recorded answer, never an early refusal or a made-up record

The host now looks a resent send id up before preparing the session. A row
that settled refused answers with its refusal before the chat is opened. A
resend whose chat cannot be opened or made ready answers unknown instead of a
refusal. A /clear in flight refuses only ids the ledger does not hold.

A send row now records the journal epoch it was admitted into. An unsettled
row with nothing written in that same epoch runs for the first time; under a
later epoch the host answers unknown instead of reconstructing a submission
it never had. The host advertises agent-session.send-answers-proof.v1.

* test(native-chat): pass the ledger row to the thread-goal rerun check

* fix(native-chat): a send's answer commits with its write, and a resend is answered before any write

A send (and /compact) settles its ledger row `succeeded` in the same SQLite transaction as the
submission or queued draft that accepts it, so a row still `pending` proves nothing was written and
a resend runs it for the first time. The unknown-before-run mark and the per-row journal epoch go.

A resent id is answered from its row and the journal before preparation starts an agent and before
any write transaction: a recorded refusal with nothing opened; otherwise the conversation is opened
(no agent start for a send) and replayed, and a conversation that will not open answers unknown.

* fix(native-chat): a ledger refusal is answered first, and a /clear refuses only a send's first run

An id the ledger refuses (expired, conflict, invalid, capacity) is answered as admission would,
with no journal read, preparation or write, so a closed chat or a read-only store answers it too.
A re-read after the replay open that comes back refused returns that refusal.

Whether a /clear is in flight is read when a send arrives and applied in the send's preparation
for a first run only: an id the ledger holds by the send's turn, including one whose earlier
attempt was queued ahead of the clear, is answered from its record. MutationPlan makes
settlesWithWrite and settledOutcome exclusive; the capability text no longer promises a refused
id never sends.

* Fix reordering workspaces with collapsed children (#25302)

* fix(native-chat): show a message Orca accepted and then failed to deliver as "Not sent" in the chat (#24710)

* fix(native-chat): keep a message the host accepted then rejected in the desktop chat as not sent

Draw it in place from the host's history, so a crash that loses the outbox no
longer makes it vanish. A later copy of the same body supersedes it; the outbox
row wins while it holds the message; the phone is unchanged.

* test(native-chat): pin the same-id rule apart from the body match

* test(native-chat): type the rejected-in-place fixture body as a text block

* fix(native-chat): let the host's row own a message it recorded and then rejected

Once the host's journal records a send as rejected, the desktop outbox lets it
go, as it already does for delivered and Stop-withdrawn sends: the host's row
shows it as not sent, with the host's reason and no Retry. The outbox keeps
only sends the host refused before recording them, which keep their Retry.
A send whose own reply says it was rejected is drawn by its outbox entry, with
no Retry, until the journal carries the row; a copy left by an earlier session
is dropped when the chat opens.

- the transcript no longer hides a host row behind an outbox entry with the
  same id or the same text; those rules and their cache are gone
- a rejected message the queue holds (a draft's hand-off, or a live card under
  its id) is drawn as its card, not as a row
- a later copy of the same text hides a rejected row only when it was sent
  once the rejection was known, so a deliberate repeat stays
- delivery notices read the same visibility rule as the transcript; a chat
  whose only rejection a Stop withdrew no longer rebuilds them per batch
- the body fingerprint helper goes back to the host, its only user

* test(native-chat): keep one row when copies of a rejected message share an instant

* refactor(native-chat): let the host's notice replace the outbox's under the same id

* test(native-chat): pass the queued card ids in the tool-stream cost transcript

* fix(native-chat): keep the host's record as what lets a rejected message go

- the outbox no longer drops a host-rejected message when a chat opens; the
  reconcile lets it go once the journal's submissions say it was rejected, and
  that drop is written to storage, so nothing reads as still owed
- a message the host rejected while the chat watched waits for its journal row
  with no Retry; one read back from storage with no row loaded keeps its Retry
  under a new id, since the host may have lost it
- the delivery notices keep the same map and notice objects across a batch that
  words every row the same, so a submission batch re-renders no row
- a rejected command such as /compact stays hidden: its own reply reports it
- the desktop transcript requires the queued card ids, with a controller-level
  test that a card holding a rejected message keeps its row hidden

* fix(native-chat): draw a queued message where the host rejected it

A message accepted to hand over later and rejected before any handover now sits
at its rejection, as a handover places one: what the agent did while it waited
happened before it, and the newest history page holds it. One handed over, or
dispatched as it was recorded, keeps its place. An older host does not move it,
so it stays at its submission, still drawn.

A failed start now rejects the queued messages and writes its row in ONE
journal append, the messages first: no reader ever meets one without the
other, and the messages still draw above the row that says why.

* test(native-chat): pin that rows written together roll back together

* fix(native-chat): draw every rejected message where it was rejected

Not only a queued message: one handed over into a turn and then rejected, or
sent directly and rejected, also sits at its rejection, in no turn. A message
in doubt stays where it was, a plain bubble: it may have reached the agent.

* fix(native-chat): decide a rejected message's Retry from the host's stored fact

- a message the host recorded and then rejected has no Retry on any mount,
  however that mount learned of it, and a Dismiss that clears it from storage;
  a send refused before the host recorded it keeps its Retry
- the rule that keeps a rejected command such as /compact out of the
  transcript moves into the one visibility function rows and notices share
- the outbox state docs say what lets a recorded message go: the client holding
  its rejected submission, whose row the host places at the rejection

* fix(native-chat): write no start-failure row when a Stop withdrew every queued message first

* test(native-chat): pass the Dismiss action in the delivery-notice hook tests

* fix(native-chat): keep a rejected message's outbox copy until its row loads

An older host leaves a rejected message where it was sent, which may be older
than the loaded window: the chat then holds the rejected submission but not the
row that draws it. The outbox copy now stays until that row loads, marked as
the host recorded it (Dismiss, no Retry, in the host's words), and leaves once
the page holding the row is loaded. Derived from the loaded rows each time.

Tests that label their projection as the phone's now pass the phone's own
setting.

* test(native-chat): type the outbox hook props that carry loaded rows

* fix(native-chat): write nothing when a journal batch settles nothing in the outbox

The outbox re-reads the journal on every batch since it waits for a rejected
message's row to load. Its reconcile now returns each unchanged entry, and the
list, as themselves (a message left in doubt included), so a batch that changes
nothing writes nothing to storage. The reconcile moves to its own module.

A copy the host recorded and rejected owes no delivery, so it no longer keeps a
hidden pane reading the journal.

* test(native-chat): count storage writes on the outbox's own storage object

* fix(native-chat): let a recorded rejected message's outbox copy leave on its own, with no Dismiss

The outbox copy of a message the host recorded and then rejected draws it only
while the host's row is not loaded, and leaves on the batch or page that loads
that row. It owes no delivery and offers no control: sending it again is a new
message. The Dismiss that let the user clear it is gone, from the outbox, the
notices and the session controller.

* Add shared workspace settings note and prevent filter modal expansion (#25300)

* fix(mobile): say that workspace sort, grouping, and filters are shared

The Manual sort option was subtitled 'Server order', but it orders by the

device on that host, which the screen never said. Relabel Manual as 'Desktop

By, Group By, and Filter titles. The note avoids naming a desktop sidebar

* fix(native-chat): a new structured chat's model list comes from the machine that runs it (#25143)

* fix(native-chat): a new structured chat's model list comes from the host that runs it

agentSession.modelCatalog builds the structured-session host like agentSession.options,
so a host with no saved chats since it started answers instead of refusing. When the
host answers unknown because its first listing runs in the background, the picker
re-reads on a bounded schedule until that listing lands. Local terminal-backed chat
skips the structured catalog when a custom launch command is configured.

* fix(native-chat): wait on the host's first model listing instead of re-reading on a timer

A new structured chat's picker read the host catalog once; on an account the
host had never listed, the answer was "unknown" while a background listing ran,
and the client re-read on a 1-30 s schedule. Replace the schedule with the
host's own completion signal:

- The host answers a cold read with `listingInProgress: true` (new optional
  field) once it has started or joined that listing. A read that passes the new
  optional `waitForListing` param awaits the same joined listing and answers
  with it, or a plain "unknown" if it failed. The at-rest options read never
  waits. A host that predates the field never sends it, so the client never
  sends the param to a host that would refuse it.
- The picker reads once per open and attach; after the host's report it sends
  one waiting read, with a 90 s client timeout above the slowest listing.
  While that read is out, the model pill keeps its label but cannot open or be
  set (typed /model included). An answer, failure, timeout, hide, attach or
  the provider's own list releases it.
- `agentSession.modelCatalog` builds the structured-session host only for a
  read that names a session (a structured chat). Terminal-backed chat's
  session-less read keeps the non-building gate, so a desktop that never runs
  structured chat never opens the session journal.

* fix(native-chat): one waiting model-list read per chat, and no late menu open

The waiting catalog read was owned by one run of the picker's effect. Attach
(a new fence), hide/show or a send re-ran the effect: the cleanup released the
model picker onto the built-in list for a round trip, and the new run sent a
second waiting read while the first, which cannot be withdrawn, kept a remote
call slot until the listing ended.

The waiting read now belongs to the chat (runtime target + agent + session):
a small registry keeps one in flight per chat, every re-run or remount joins
it, and the entry is deleted when the read settles. The picker hold is derived
from that entry being in flight, so it lasts across attach and hide/show and
ends when the read settles, the provider reports its own list, or the pane
switches to another session. Answers still pass the stale and record checks.

A bare /model typed while the list loads no longer opens the model menu by
itself when the list lands: the menu stays keyed on the request, and only its
initial open is suppressed while pending, so the request is spent shut and the
end of the pending period never remounts it.

* fix(native-chat): release the model picker in the same commit as the host list

When the waiting catalog read settled in the chat that started it, the
registry dropped its entry and told subscribers first, and the host list was
applied a few microtasks later. React committed once with the picker enabled
on the built-in list, then again with the host's list.

Joiners now hand the registry their apply callback, and the registry runs
every joiner (with the answer, or nothing when the read failed or timed out)
before it deletes the entry and notifies. The release and the list land in one
commit. An effect cleanup leaves the wait instead of flagging itself stale.

* fix(runtime): queue model catalog reads in the long-wait lane

A model catalog read that waits on a host's first listing replies only when
that listing ends, yet it took one of the 8 foreground call slots for its
server. Enough chats opened during one cold listing would stall that server's
sends and interrupts until a wait settled.

agentSession.modelCatalog now joins worktree.rm in the long-wait lane: same
concurrency, counted apart from the foreground calls. The queue classifies by
method only, and a warm catalog read answers at once, so the whole method
moves.

* Fix: settle sortEpoch in store to prevent React update depth exceeded (#25313)

* fix(sidebar): stop Manual sort from mirroring sortEpoch into state

In Manual mode the sort hook copied every sortEpoch bump into state from an
effect, adding a nested React update per bump. A burst of store bumps at
startup stacked those into 'Maximum update depth exceeded' (React #185).
Manual now reads the live epoch directly; debounced modes are unchanged.

* feat(sidebar): tell people when a drop switches sort to Manual

Reordering by drag still switches the sidebar to Manual so the drop sticks,
but it used to happen silently. Show a toast with a 'Back to <previous sort>'
action; it retires itself on any later sort change so it can't override a
newer choice. Drops while already in Manual stay silent.

* feat(store): settle sortEpoch in the store instead of in React state

Add settledSortEpoch plus a 3 s settle timer owned by a store listener
installed in the state creator. Every write path (slice actions, the web
session sync patch) goes through it, so the settled value stays correct
with no sidebar mounted. Manual, a sort-mode switch, and a bump that
changes the non-archived row count settle in the same notify; other bumps
restart the window. A reset that lands settled clears the timer, and the
disposer runs on HMR teardown.

* fix(sidebar): read the settled sort epoch instead of mirroring it into state

The sort hook no longer copies sortEpoch into React state from an effect in
any mode; it reads the store's settledSortEpoch directly. That pattern added
a nested update per bump and stacked into "Maximum update depth exceeded"
(React #185) under flushSync bursts. Tests cover Manual, add/remove, burst
reset, no-bump row changes, mode switch, and 80 flushSync bumps in Recent
while worktrees are added.

* fix(store): settle bumps when rows update during pending window

Detect structural changes on worktreesByRepo updates in addition to sort
epoch changes. When a row arrives without its own bump during a pending
settlement window, the changed composition must still trigger settlement.

* fix: update Caffeinate tooltip copy about MacBook lid behavior (#23091)

Update tooltip and settings pane help text to accurately describe
Caffeinate's behavior: it prevents idle sleep while active, but
MacBook lid closing may still trigger sleep per device power policy.
The previous copy incorrectly suggested Orca could prevent lid-close
sleep.

* Simplify the phone-control and phone-size terminal dialogs (#25307)

* Redesign the phone-control and phone-size terminal dialogs

Drop the eyebrow label and circled icon, shorten the copy so it no longer
restates the buttons, and give each state one primary action with a quieter
"all" action. Collapse moves out of the button row into a Minimize icon in
the corner. Behavior is unchanged.

* Point the phone settings copy at the renamed Restore button; drop dead ko overrides

The phone app and desktop update independently, so name only "Restore",
which matches both the old and new desktop banner labels.

* fix(terminal): stop old output bleeding into Claude's screen when revisiting a remote tab (#24926)

* fix(terminal): leave the alt screen before replaying a pushed host snapshot

A remote terminal running a full-screen agent (Claude Code) could show old
output (e.g. a setup script's pnpm log) interleaved with the agent's screen
after switching back to the tab. The host's pushed snapshot is a serialized
image that starts on the normal buffer and enters the alternate screen
itself, but the replay drain cleared with ESC[2J without leaving alt. The
image's history painted into the agent's screen, its own ?1049h was a no-op,
and the agent's diff paints landed on top of the stale cells.

The remote-runtime transport now marks snapshots as serialized images, and
the drain grounds them with the shared snapshot prologue (switching to the
normal buffer first). Raw byte replays (SSH relay ring buffers) keep the
in-place clear.

* fix(terminal): paint folded remote snapshots from the normal buffer everywhere

Review follow-ups:
- Rename the flag to carriesNormalBuffer: what the painters rely on is that
  the image starts on the normal buffer and enters alt itself.
- Hidden-output restore had the same bug for remote requested snapshots
  (history folded into data, alternateScreen set): the painter entered alt
  first and painted the normal buffer into the TUI's screen. Requested remote
  snapshots now carry the flag and take the normal-buffer start.
- Flag pushed snapshots replayed after a cancelled shutdown too.
- Pushed snapshots carry only the screen, so over a live TUI the drain keeps
  the normal-buffer history it covers instead of wiping it.
- Read the pane's buffer after queued output parses.
- Tests compare whole buffers against a fresh terminal, use production image
  shapes, and pin the raw-replay path with the same oracle.

* fix(terminal): let the replay drain own the recovery snapshot clear

The recovery prefix's own \x1b[3J ran after the drain's prologue and wiped the
history the drain keeps under a live TUI. Keep only the latch release, which
still makes an empty recovery snapshot non-empty so it is applied.

* fix(terminal): keep the recovery snapshot's own screen clear

Consumers that write recovery snapshots straight into xterm (no replay drain)
rely on the prefix clearing the stale screen. Restore \x1b[2J\x1b[H and drop
only \x1b[3J, which wiped history the image does not carry.

* test(terminal): drive the drain with the real recovery payload

The multiplexer prepends its own screen clear; replaying that exact payload
pins that the prefix cannot wipe the history a TUI covers.

* fix(terminal): keep TUI-covered history only when the grids match

Second review follow-ups:
- A pushed image carries only the host's screen; the pane's frozen history
  continues it exactly only on the same grid. On another grid keeping it
  duplicated or dropped lines, so the image replaces it there.
- Tests replay the pane's writes and grid changes into a real terminal and
  compare whole buffers with the host, including a mismatched-grid case.
- The split branch shares the normal-buffer preamble; drop the now
  single-use abort helper.
- Type serializeBuffer as RemoteRuntimeSnapshotImage so the flag is carried
  by type, not by object pass-through.
- Register the grid and raw-replay cases in the reliability gate.

* fix(terminal): keep TUI-covered history only while the host is still on alt

The drain kept the pane's history whenever the pane was on the alt screen. If
the host's TUI exited while the tab was hidden, the shell wrote past that
history and the kept lines no longer continued the host's screen. Require the
host's own alternateScreen too; an absent flag proves nothing, so the image
replaces history as on main.

Also: one buildSnapshotReplayPreamble for every first replay write, the drain's
image and raw clears as separate branches (raw byte-identical to main, comment
restored), and a single paneAtSourceGrid check.

* fix(terminal): gate kept history on the host's shell-owner proof

The host sends alternateScreen only with terminalOwner 'shell', i.e. once it has
proven the TUI exited, so `alternateScreen === true` never held for a live TUI
and the drain wiped the history it should keep. Replace the history only once
the host proves the TUI exited; tests now use production snapshot shapes. Move
the relay-overlap comment into the raw-replay branch it describes.

* fix(terminal): keep TUI-covered history only on a proven shared grid

An image without its grid cannot prove the pane's history continues its screen,
so it now replaces history. Also update a stale recovery-prefix test comment.

* test(terminal): replay host-serialized snapshots through the real wire and drain

Hand-written replay meta hid a gate that production never satisfies. Drive the
host's own emulator, ownership mirror, serializer and recovery publisher through
the real wire, client parser, remote transport and pane drain, for a live TUI
and after the host proves it exited.

* fix(terminal): repaint only the alt frame over a live TUI, leaving history alone

Keeping the pane's history by clearing only the normal screen assumed a pushed
image carries no history, which the host does not guarantee: a 0-row push can
reuse a concurrent requested capture, and its history then landed twice in
scrollback. It also wiped history on a grid mismatch, where main kept it.

When pane and image are both on alt, the image's normal part adds nothing (the
normal buffers froze together), so paint only its alt payload after an alt-side
clear, split at the host's own boundary (splitAtAlternateScreenEntry, now shared
with the daemon). Any other image paints from the normal buffer. This drops
keepScrollback, the owner and grid gates, and the recovery-prefix change, so
history behaves exactly as on main.

* test(terminal): pin the parse wait and the cancelled-shutdown flag

Final-review follow-ups: a drain test where the TUI's ?1049h is still queued
when the image arrives, and a transport test replaying a push buffered during a
cancelled shutdown; each fails when its guard is removed. The requested-image
test now names the exited-TUI case it covers, requestSnapshot shares the
snapshot image type, and the clear comment no longer implies every clear drops
scrollback.

* Clarify keep-awake tooltip behavior by platform (#25323)

* fix: make keep-awake tooltip lid behavior platform-aware

Extracted platform-specific lid behavior notes into a reusable function and
updated the keep-awake tooltip to show accurate descriptions for each OS:
macOS explains that closing the lid may still sleep the device, Windows
references device power settings, and Linux clarifies Orca's lid-close request
behavior. Updated copy to be device-agnostic instead of Caffeinate/MacBook
specific.

* fix: clarify macOS keep-awake tooltip copy and add translations

Update agent keep-awake descriptions on macOS to accurately explain that the feature prevents idle sleep (not all sleep modes) and only works with the lid open. Add translations for Spanish, French, Japanese, Korean, and Chinese.

* fix(native-chat): show "Sending…" on a message until the host confirms it (#24606)

* fix(native-chat): no "unconfirmed" line while Orca resends a send on its own

A send whose answer was lost (for example after reopening the chat mid-send)
showed "Message delivery is unconfirmed." with a Retry for the moment before
the automatic resend under the same message id confirmed it. One rule now
decides both: the resend runs, and the notice stays quiet, only while the
send's answer is lost, the user never retried it, it was not still going out
when the user pressed Stop, and the host has no record of it yet. Once the
host has any record of it, the line and Retry are exactly as before.

* fix(native-chat): say "Sending…" on a message until the host confirms it

A send whose answer was lost was resent quietly under the same id but looked
like any delivered message. Every message still in the outbox with no failure
to show now says "Sending…", muted, in place of its time, until the journal
holds a row for it. Rows that say a message did not go through keep only that
line and its Retry. The notices read the outbox through the same reconcile as
the transcript, so a row that lands clears the marker in one step.

* fix(native-chat): keep "Sending…" until the host has the message, in the time's slot

A message the user retried, a second message in doubt, or one requeued over a
rejected row had a journal row that did not hold it, so it showed nothing and
looked sent. "Sending…" now stays until the row is pending or accepted.

The marker took the place of the whole meta row, so the copy button went away
while sending and the row jumped when it cleared. The row now stays mounted:
copy keeps its hover reveal and "Sending…" sits where the time goes.

* test(native-chat): move the delivery probe tests into their own file

NativeChatStructuredSessionDelivery.test.tsx went over the 800-line lint
limit after main was merged. The eight tests for the automatic probe of an
unconfirmed message move unchanged to
NativeChatStructuredSessionDelivery.probe.test.tsx, which uses the shared
structured-session test harness for its mocks. The outbox seeding and probe
clock helpers move into that harness so both files share them.

The at-most-once reliability gate now lists the new file, with a fresh
evidence run.

* Tighten spacing in workspace deletion confirmations

* Address deletion dialog review and synchronize localization catalogs

* fix(editor): restored tabs for files outside your projects no longer fail with Access denied (#24489)

* fix(editor): read files outside projects without a grant a restart loses

A file opened from outside every project (e.g. ~/notes.txt from the floating
workspace) read through an in-memory grant. After a restart the restored tab
only renewed that grant when it stored a full path, so a tab saved relative to
the floating workspace folder failed with "Access denied" and Retry repeated it.

Single-file reads (read, stat, exists) and open-editor-tab saves now resolve a
path outside every project in place. Paths inside a project keep the full
containment check, so a project's symlinks still cannot escape it, and every
other write stays inside projects.

* fix(editor): re-grant restored floating-workspace tabs by owner, not path shape

Problem: a file opened from the floating workspace (e.g. ~/notes.txt via
Cmd-click in the floating terminal, the floating markdown picker, or a .md
opened from the OS) loads until restart, then shows "Access denied: path
resolves outside allowed directories". Main's external-path grants live only
in memory. On restore the editor re-granted only tabs that stored an absolute
path, but floating tabs store a path relative to the floating root (~ by
default), which is deliberately not an authorized root, so they were never
re-granted. Restored floating notebooks also failed to start a kernel.

The previous commit on this branch let main read and save any path outside a
project without a grant. That widened fs:readFile/stat/pathExists for every
caller, including automatic reads of untrusted content (markdown preview
images), which opened a Windows UNC credential leak and a /dev/zero
main-process memory blowup. This reverts that model entirely.

Fix: one helper decides which client-local path a tab needs re-granted by
ownership: a floating-workspace tab, or a tab stored outside its own project.
It never grants paths a local project root covers (a grant would also
authorize a project symlink's outside target), and skips SSH-owned,
runtime-owned and not-yet-hydrated owners. Every reader that can touch a
restored tab before or without the editor loader uses it: the loader, the
restored dirty-tab conflict scan, and the paired-mobile markdown bridge.

* fix(editor): let main decide which restored-tab paths a project already covers

Problem: the restore re-grant helper decided "already inside a project" in
the renderer from its worktree list. At startup that list only holds repos
the session references, so a floating tab inside an unlisted repo was granted
(including a symlink's outside target), and the renderer's path matcher
disagrees with main's on WSL \\wsl$ vs \\wsl.localhost, which stranded a
folder-workspace tab with "Access denied" after restart. The helper also
treated a folder workspace with a missing or ambiguous host as local.

Fix: the renderer now decides only by owner (a floating-workspace tab, or a
tab stored outside a project whose owner is explicitly local) and asks main
with `skipIfInsideAllowedRoots`. Main checks the path against its own allowed
and registered roots, in both the named and canonical-parent spelling against
both root spellings: a path a project covers gets no grant, an alias spelling
of a project path gets only that spelling, and a project symlink's outside
target is never granted. Explicit-open grants (Cmd-click, drag, explorer) are
unchanged. Tests now prove each reader waits for the grant before reading.

* fix(fs): decide a restored tab's project membership from every ancestor's real path

Problem: the restore re-grant decided "inside a project" from the named path
and the real path of its parent only. When a tab path crossed a project
directory symlink and named the project through a spelling that was neither
the registered root nor its realpath (a second alias, a `..` segment, a case
variant on a case-insensitive disk, a /var-style alias of an ancestor), no
check matched, the path took the full grant, and the symlink's outside target
became readable and writable.

Fix: a path is inside a project when the named path is inside a root, or the
real path of any ancestor folder is inside a root in its registered or real
spelling. Such a path gets at most its named spelling, never its realpath. An
ancestor that fails to resolve for any reason other than "missing" now fails
closed to the named-spelling grant instead of falling through to the full one.
Tests cover each spelling; the non-symlink case also runs on Windows.

* fix(fs): read local files as regular files only, from one bounded handle

Problem: fs:readFile stat'ed a path and then read it to EOF. A character
device such as /dev/zero reports size 0, passes the size limit and never ends,
so the main process buffers until memory runs out; a FIFO hangs the open.
Writes could also target an existing device or FIFO.

Fix: every local fs:readFile (editor and log snapshot) opens the path once,
non-blocking, refuses anything but a regular file, and reads the size check,
binary probe and content from that same handle, capped at the limit even if
the file lies about its size. The AI Vault log tail opens non-blocking too,
and fs:writeFile refuses an existing non-regular target.

* feat(fs): let desktop file requests declare their shape

Problem: main decided every local file request against one allow-list plus a
set of in-memory grants the renderer had to recreate after every restart, so
a file the user opened outside a project (for example from the floating
workspace) was denied once Orca restarted.

This adds the request shape the common pattern uses, alongside the grants for
now:
- no shape (the default): the path must be inside a project root main
  recognises, symlinks included. Desktop requests also accept the app-owned
  floating-workspace folder; paired-client RPC never does.
- user-file: a single file the user named by absolute path, used in place.
  Only fs:readFile/stat/pathExists and saving (fs:writeFile) accept it.
- document-resource: an image or PDF a document references, limited to every
  project root when the document is in one, else to the document's folder,
  and refused by path text before any disk or network access.
Notebook kernels and AI Vault log tails check their open file as user-named.

* feat(editor): send each local file request's shape from the renderer

Problem: after a restart, a tab opened outside every project (a floating
workspace file, a file opened by absolute path, an OS-opened markdown) could
only be read if the renderer first re-granted its path, and readers that ran
before the editor loaded the tab had no grant at all.

The renderer now says what kind of request it is making, and main checks that:
- A persisted tab opened outside its owner's root (floating workspace, or an
  absolute stored path) whose owner is explicitly local reads and saves as a
  user-named file, from every reader: the editor loader, the restored-tab
  conflict scan, the change banner and compare dialog, the paired-phone
  markdown bridge and the save queue. Project tabs stay inside their root.
- Clicks, drops, typed paths and browser-opened notebooks stat as user-named.
- Markdown preview and rich-editor images are document resources, limited to
  the document's roots or folder. Images the user pasted or attached into a
  chat show as user-named; agent images stay inside the project.
- The image cache keys on the shape, so one shape's image never answers
  another's request.
A ratchet test lists every renderer file allowed to create a user-named
request.

* refactor(fs): delete the in-memory path grant system

Problem: main kept a set of paths the renderer had asked it to allow
(fs:authorizeExternalPath). The set lived only in memory, so a file the user
opened outside every project could be read until Orca restarted and was then
denied, and every new reader of a restored tab had to remember to recreate
the grant first. Three rounds of re-deriving grants at restore each found
another reader or path spelling it missed.

Now that every desktop request declares its shape, nothing needs a grant:
- delete the grant set, authorizeExternalPath, the restore re-grant from the
  earlier commits on this branch, the fs:authorizeExternalPath channel and its
  preload and web-client entries;
- delete every renderer grant call (terminal and markdown link clicks, drops,
  typed paths, the file explorer, AI Vault logs, chat attachments, browser
  notebooks) and every main one (floating markdown picker and folder, OS-opened
  markdown, keybindings.json, pasted images, import and upload sources);
- the floating workspace's picker-approved folders stay a terminal-cwd
  allowlist only.
Main now holds no per-path permission, so a restart can't change any answer.

* feat(editor): open project links that lead outside the project as named files

Problem: a file inside a project that is a symlink to something outside it
opened fine from the file explorer or a terminal Cmd-click, then showed
"Access denied" after a restart: its tab was stored as a project file, and a
project request is refused when it resolves out of the project. A folder link
out of the project expanded in the explorer until restart and then failed with
a raw access error.

Now the click decides and the tab keeps that decision. Both gestures stat the
path inside the project first; if only the user-named check passes, the path
leads out of the project:
- a file opens by its absolute path, so it reads and saves as a file the user
  named, the same before and after a restart;
- the explorer does not follow a folder link out of the project and says so
  ("This folder links outside the project, so it can't be opened here.").
Paths that stay inside the project still open as contained project tabs. Also
drops the AI Vault "path not authorized" message, which nothing shows now.

* chore: drop the casts the changed-code quality gate flags on this branch

The FileContent casts in the editor loader and the paired-phone markdown
bridge were never needed (the read result is already assignable). Tests stub
window.api through vi.stubGlobal and pass narrow stores without casting; the
one test store that still needs a cast states why.

* fix(fs): load chat images by type, and keep escaping project links readable

Problems found in review:
- Chat transcript images were trusted by message role: any user-role
  "[Image: source: <path>]" (an injected Claude record, `orca terminal send`,
  a paired client's image-ref) became an automatic user-named read as the row
  scrolled into view, of any file type, and on Windows a network-share path
  would have opened an SMB connection to that host.
- A document image named like an image but linking to a text file
  (logo.png -> .env) was read as text.
- Windows device names (NUL.png, COM1.jpg) passed the path-text check of the
  automatic image loads.
- A project symlink leading out of the project, opened by a typed path, a
  tab-strip drop or a browser file:// notebook, was stored as a project tab
  and immediately refused.

Fix:
- New chat-image request shape for every transcript image and the composer
  preview, whoever's turn named it: an absolute local path whose requested and
  real targets are image files, a regular file, size-capped; network-share and
  device-namespace paths and Windows device names are refused by path text
  before any filesystem call. Pasted screenshots still show after a restart,
  and agent images outside the project now render.
- Document resources check the real target's type too, and refuse Windows
  device names by path text.
- Typed paths, tab-strip drops and browser notebooks stat through the same
  check as the explorer and terminal, and open an escaping link by its
  absolute path.
- Tests pin the shape at the change banner, compare dialog, markdown preview
  and image prewarm; a second ratchet lists every file that can open a tab the
  tab rule reads as user-named, and its comment says what it can't see.
- Stale grant wording removed.

* fix(fs): tighten automatic image loads and the project-link check

Problems found in review:
- Two unit tests went red on this branch: the browser-share test still
  expected reads without a shape, and the rename test's electron mock had no
  app, which the desktop root check now needs.
- The device-name check ran on the raw path, so `NUL.png\.` or
  `COM1.png\x\..` (reachable from markdown `![](NUL.png%2F.)`) reached the
  filesystem; a document image whose real target was a device name passed.
- Chat images in a project that lives on a Windows network share no longer
  rendered, though the markdown preview showed them.
- Any failed project check (a missing file, a dropped connection) was taken
  as "this link leads out of the project" and opened as an absolute tab.
- Every local read allocated about 2 MiB, even for a tiny image.

Fix:
- Device names and device-namespace paths are checked on the resolved path
  and on the real target, for chat images and document resources alike.
- A network-share path in an automatic load is read only inside a project
  root (the user chose that share when adding the project); anywhere else it
  is still refused by path text before any filesystem call.
- Only main's "outside allowed directories" refusal marks a project path as
  leading out of the project; other errors surface as before. The message now
  lives in shared code so both sides agree on it.
- Reads size their first buffer from fstat and confirm EOF with a 1-byte
  probe; a file that grows past its reported size is still read in bounded
  chunks up to the cap.
- Fixed the two red tests.

* refactor(fs): name file access by its role, not its structure

Problem: the static-analysis anti-slop check failed the PR because the new
code named the request's file access a "shape" (`shape`, `RequestShape`,
`TabShape`), which describes structure rather than the role.

Rename the main-process module filesystem-request-shape.ts (and its tests) to
local-file-access-resolution.ts, rename the symbols to fileAccess,
FileAccessResolution and TabFileAccessFields, and say "file access" or
"access kind" in the comments and test names. No behaviour change.

* fix(fs): refuse every Windows device-name spelling in automatic image loads

Problem: the device-name check split a file name only on '.', so names such
as NUL:.png, COM1:.png, NUL:stream.png (an alternate data stream) slipped
through, and CONIN$, CONOUT$, CLOCK$, COM0 and LPT0 were not listed. Those
reached the filesystem from a document or chat image before being refused.

Split on ':' as well, list the missing device names, and test each with
Windows path rules and zero filesystem calls. Also cover the case of a local
link that leads onto a network share outside every project (refused for chat
images), and correct the shared comment on chat-image access.

* fix(editor): let users rename and insert images into files opened outside projects

Renaming a file opened outside every project (tab double-click, editor
header) and inserting an image into such a markdown document failed with
"Access denied", even before a restart: both writes only passed the
project-root check. Document resources and chat images were also limited
by file type more strictly than users expect.

- Add a "document-folder" access kind for writes beside a document the
  user opened: main allows renaming only that document, to a name inside
  its own folder, and importing new files only into that folder, checked
  by path text and again by real path, with Windows device names refused.
  The renderer sends it only for local user-named, writable tabs (rename,
  its undo/rollback, image insert); SSH and runtime requests never carry it.
- Document resources: drop the image/PDF type allowlist; folder
  confinement, regular-file reads, the cap and path-text refusals remain.
- Chat images: judge only the real target's type, against every
  previewable image type (AVIF added).

* fix(fs): a declared file-access kind never refuses what the project check allows

A full-path tab for a file inside a project (for example a link that
leads out, opened by its absolute path) was renamed under the
document-folder rule, which limited the new name to the file's own
folder, although the same rename with no declared access could move it
anywhere in the project. Any declared kind could be stricter than the
default in the same way.

Every desktop local file request now goes through one resolver,
resolveLocalRequestPath: it runs the default project check first (roots,
Orca's floating folder, symlink containment, outside-root path text
refused before any filesystem call) and only on a refusal applies the
declared kind's rule, which adds paths outside projects. Reads, saves,
rename source and target, and import destinations all use it, so a new
kind gets the rule for free. Automatic loads (document and chat) still
refuse Windows device paths and names by text first, even inside a
project; a device is never a file to show.

The document-resource rule no longer needs its own project branch, and
chat images no longer re-run the roots check for shares.

* fix(fs): symmetric outside-project renames, notebook real folder, same-share images

- Renaming a file opened outside every project accepted a name in a
  subfolder (`archive/todo.md`), but the Undo and the rollback rename,
  declared from the moved file, were then refused and the file stayed
  moved. A rename under document-folder access must now land directly in
  the document's own folder (checked by path text before any filesystem
  call), so rename, Undo and rollback are symmetric. Image import still
  accepts the folder or a folder under it. Inside projects the default
  check still allows any in-project target.
- A notebook opened through a link inside a project started its kernel in
  the link's folder instead of the real file's folder (main's behaviour),
  because notebook and AI Vault log-tail paths skipped the project check.
  Both now resolve through resolveLocalRequestPath (project check first,
  then the user-file rule).
- A markdown file opened from a Windows share outside every project could
  not show the images beside it. Document images on a share are now
  allowed inside the document's own folder; the folder text check refuses
  every other host and share before any filesystem call.
- resolveDesktopAuthorizedPath is async, so a synchronous failure in the
  default check rejects like any other refusal.

* fix(fs): refuse share images outside projects again; keep renames and kernels as on main

- Reverts the same-share document image rule from the previous commit.
  Its folder check compared hosts case-insensitively, so a host spelled
  with U+212A KELVIN SIGN (or a decomposed accent) passed as the
  document's own share and was contacted, reopening the network
  credential leak. Document and chat images on a share outside every
  project are again refused by path text before any filesystem call;
  tests now cover the look-alike hosts with zero filesystem calls.
- Renaming a file opened outside every project into a project folder
  passed the project check, but its Undo (declared from the new path)
  was refused and the file stayed moved. When the rename source is
  allowed only as the opened document, the new name must now land
  directly in the document's folder even if a project would accept it
  (resolveLocalRenamePaths).
- A notebook opened through a link outside every project started its
  kernel in the link's folder; main used the real file's folder. The
  kernel cwd is now the real file's folder in every case.

* fix(fs): a file opened outside every project renames to any path, and keeps its access

Renaming a document the user opened (floating workspace or full-path tab) now
follows the user-file rule: the source must be the opened document, and the
new path can be any absolute path, so a rename into another folder, a
subfolder or a project works, and its Undo (declared from the moved file)
comes back from there. Any other rename keeps the project check only. Remove
the same-folder rename rule and its tests; image import stays in the
document's own folder.

After a move, a tab stored by its full path keeps its full path instead of
being recomputed project-relative, so it keeps user-file access for save,
the next rename, image insert and restore after restart. Folder moves go
through the same remap.

Also un-export unused resolver exports and avoid a copy for single-chunk reads.

* fix(test): pass getInsertionRange in the image-insert access test (#25351)

#25176 replaced insertPos with getInsertionRange and #24489 added a test
using insertPos; together they broke main's typecheck.

* Update README downloads badge

* fix(native-chat): start a new chat after an earlier start failed (#24917)

* fix(native-chat): start a new chat after an earlier start failed

A chat whose start the host refused stayed registered under its agent and
workspace, so the + menu and new-tab search kept that agent disabled with a
spinner, and any later "new chat" for that agent (for example "Send notes to
> New agent") restarted the failed chat instead and dropped its own prompt.

Only launches in flight now hold the agent/workspace slot that later starts
join. The registry keeps every launch by session id and derives the holder,
so a failed chat keeps its own Retry while a new start makes a new chat.

* test: import the launch status from its own module

* test: name the owning host on the launch intents the new tests build

* fix(native-chat): a new start never joins an unconfirmed or retried chat

A new start for an agent joined a chat whose create answer was lost, or a
failed chat whose Retry was in flight, and dropped its own text: the
source-control "Fix with AI" action reported success with nothing sent,
"Send notes to > New agent" sent nothing, and after a reload the text became
an unsent draft in the old chat.

Only a new start's own first create now coalesces later starts (double click,
two callers at once). Each attempt records whether it is that first create or
a Retry/re-check of an existing chat; an unconfirmed or retried blank chat
keeps its own Retry and a new start opens a new chat with its text. A resume
still re-checks or joins its conversation's launch, since the host refuses a
second adoption.

* fix(native-chat): a different new request always opens its own chat

A new start used to join any blank chat still in its first create or still
sending its opening text, so a second "Fix with AI" for another check, or
notes sent to a new agent, landed in that first chat. Each first attempt now
keeps the request it was started with (its text and whether it is sent or
drafted). Only a repeat of that request (a double click, a retried call)
joins it, and it shares the text already staged, so the text is sent once.
Any other request opens a new chat with its own text. The + menu, new-tab
search and send-notes menus disable an agent only when their own pick would
join. Resume launches are unchanged.

* fix(native-chat): an empty chat still starting takes the first text sent to it

A blank chat that is still starting (a + pick, the empty-workspace default
chat) is empty, so the first request with text, such as notes sent to a new
agent, now goes into it instead of opening a second chat beside it. That
request becomes the chat's own request: an identical repeat joins and is sent
once, and any other request opens a new chat.

Move the logic that decides which launch a start joins out of the launch
registry into its own module, so the registry stays under the line limit
once #24904 lands beside it. Pin that a repeat arriving while the opening
text is still sending is sent once.

* test: an empty chat delivers the claiming text the way its request asked

* fix(native-chat): only a chat its user has not used yet takes another request's text

A blank chat that is still starting was claimable by the first request with
text even after its user had sent a message into it or typed into its
composer, so notes or a Fix with AI prompt could land in a conversation the
user had already started. Emptiness is now read from what the chat holds:
nothing in its outbox and no text in its composer draft. A chat its user has
used stays theirs, and the request opens a new chat.

If the claiming text cannot be saved, the claim is not recorded: the request
falls through to a new launch, whose save failure shows on that chat as for
any new launch, instead of reporting a failure nothing showed.

* fix(notes): notes handed to a send leave the next send until it settles

Notes sent to an agent stayed in the notes shelf until their chat delivered
them, so a second "Send notes" made while the first new chat was still
starting collected the first notes again. With every different request now
opening its own chat, those notes reached two chats.

When notes or browser annotations are handed to a send (a new agent, a
running agent from the menu, or a sidebar agent row), they are held in
memory against that send's own delivery result and left out of the next
send. Delivered notes are removed as before; a failed, refused or
undelivered send releases the hold, so they come back for the next send.
The notes menu now builds each scope's prompt from the notes it will send.

* test: give the annotation tray fixture its hand-off callback

* fix(notes): offer no send when every note is already on its way

When every note or annotation in a send is held by an earlier send still in
flight, the built prompt is empty. The notes menu already disabled its
trigger then, but its New agent rows still started an agent with no text,
the annotation Send buttons still opened, and a sidebar agent row could be
sent an empty prompt. The New agent rows, the annotation Send buttons and the
sidebar send now offer nothing when there is nothing to send.

* fix(notes): a new chat's staged prompt decides when its notes leave the shelf

Notes sent to a new agent were released back to the shelf as soon as the
chat's start failed, while that failed chat kept the same text staged for its
own Retry. Re-sending and pressing Retry put the notes in two chats, and Retry
alone left delivered notes listed as unsent.

For a new chat, the notes now follow the prompt it staged: held while that
message is in the chat's outbox, cleared from the shelf when any dispatch
(Retry or re-check included) sends it on, and back on the shelf when the
chat is closed and its outbox thrown away. A paired server's chat is found
once its start settles. Running-agent sends keep their own result.

While notes are only on their way, the send button reads "Sending…" rather
than "All notes sent".

* fix(notes): a new chat's saved message keeps its notes out of another send across a reload

The hold that keeps notes sent to a new agent out of the next send lived only
in memory. A reload while that chat had not yet sent them put the notes back
on the shelf while the chat's saved message still carried their text, so a
second "Send notes" sent them twice.

The staged message now saves the send keys of the notes it was built from.
The shelf treats a note as on its way while any saved message carries its key,
read from the saved outboxes on first use and kept current by the outbox's one
write funnel. When a message carrying notes is sent on (its own start, a Retry
or the re-check), those notes are cleared from their shelf; when it is thrown
away with its chat, they come back. Browser annotations sent to a new chat use
the same keys while the app runs. Running-agent sends keep their in-memory hold.

This replaces the per-message watch and outcome promise from the previous
change.

* fix(notes): release a gone chat's notes, and clear sent ones in the web client too

Two gaps in keeping notes out of another send while a saved chat message
carries them:

- The web client never installed the clearing that removes notes once a
  chat sends them on, so after a Retry there the notes stayed listed. It is
  now installed, once per renderer, by the background services both the
  desktop and the web client load with App.
- A saved message carrying notes was thrown away only by this window's own
  close. A chat closed from the phone, another window or while Orca was off,
  or closed here without a known host, kept its notes held for good. A chat
  the host stops listing (affirmed, and not a launch still starting or
  failed) now has its queued messages thrown away once that sync lands, as
  does a close that can name no host, so the notes come back.

* Revert "fix(notes): release a gone chat's notes, and clear sent ones in the web client too"

This reverts commit ae0b9f3fea67d3073be8c8336335ad7527ed65b1.

* Revert "fix(notes): a new chat's saved message keeps its notes out of another send across a reload"

This reverts commit b88d0dc2cc78be26b0fe0b33fd76285b2172447d.

* fix(native-chat): a new chat joins only a re-delivery of the same user action

"The same request" was recognised by its content (agent, workspace, trimmed
text, sent or drafted), which split one action whose text changes between
deliveries ("Fix with AI" re-fetches logs) and merged two different actions
that happen to carry the same text.

Each user action now mints one request id where it is handled (the click,
menu pick, notes send, shortcut, Fix with AI press, quick command; a worktree
create uses its creation id; programmatic starts mint once at their entry)
and passes it through the launch plan, its verdict and the structured launch
options, where it is required. A new start joins a chat only when its first
attempt carries the same id: a double click or a caller retrying its own call
makes one chat and sends the first delivery's text once; any other action
opens its own chat, whatever its text. An empty chat that is still starting
is still claimed once by the first action with text, and then belongs to that
action's id. Resume launches keep joining their conversation's launch.

The + menu and new-tab search no longer grey out an agent while one of its
chats starts: every pick is a new action and opens its own chat. The id lives
in memory only; nothing reads it after a reload (a restored launch is reached
by its session id through Retry, never joined).

* fix(native-chat): a new chat with no text reuses an empty one instead of stacking another

Two bare "+ > Claude" picks (or new-tab search, the new-agent shortcut, the dashboard) opened two
empty chats. A request with no text now focuses an existing empty chat for that agent in that
workspace: one still starting (joined in the launch, as a re-delivery is) or one that published and
sits idle (its host's journal holds no request, read live from the status feed). Empty also means
nothing queued, no composer text or images, and no launch draft its composer has not taken. Failed,
unconfirmed, resumed and other-agent/workspace chats are never reused. A request with text still
opens its own chat, or claims an empty starting one as before; request-id dedupe is unchanged.

* fix(native-chat): a new chat with no text reuses an empty chat only in the split it was opened from

Pressing + in the right-hand split focused an empty chat sitting in the left-hand split. The reuse
now looks only in the tab group the pick targets (the caller's group, else the workspace's active
group, which is where its tab would open); a pick in another split opens a new chat there. Applies
to both an empty chat still starting and one that published and sits idle.

* fix(native-chat): text sent to a new agent claims an empty starting chat only in its own split

Notes sent from the right-hand split could land in, and focus, an empty chat still starting in the
left-hand one. A request with text now claims an empty starting chat only in the tab group it opens
in, the same rule a request without text follows; elsewhere it opens its own chat there.

* fix(test): give async image-insert store mocks the openFiles list (#25357)

#25176 and #24489 landed together and collided in
insertRichMarkdownImageFromPath. #25176 added three test files whose
@/store mock returns { settings, folderWorkspaces, worktreesByRepo }.
#24489 made the same function look up the open document with
state.openFiles.find(...) to pass document-folder access to the import.
Under the mock, openFiles is undefined, so the lookup throws, the catch
shows "Failed to insert image", and no image is inserted -- 38 tests
fail on main.

The real store always carries openFiles, so production behavior of both
PRs is intact; the mocks were just written against the pre-#24489 shape.
Add openFiles: [] to the three mocks.

* fix(relay): skip the dead-cell sweep's host scan when no cell qualifies (#25350)

evacuateDeadCells ran one query that joined every assignment to its cell's
liveness and fence state, ordered by primary key with LIMIT 100. In
production no row ever matched (the only dead cells are stale existing-only
cells without a committed fence), so the planner walked the whole
relay_assignments primary key every call: 551 ms mean over 85k calls,
~12% of relay database time.

A cell-level pre-check now evaluates the predicate's cell-only half over
the ~33-row cell tables (3 ms in production). It is a superset of the cells
the host query can act on, so the sweep returns early when it is empty and
otherwise restricts the host query to those cells. The host predicate is
unchanged.

* fix(relay): prune released control-connection reservations in bounded batches (#25352)

relay_control_connection_reservations was never deleted: 13.8M rows and
9.1 GB in production, 99.999% of them in state 'released' and ~400k more
a day. Nothing reads a released row (every reader filters it out by
state), but each placement still locks all of its host's rows, ~160 on
average.

A new director sweep step deletes released rows older than a day. It walks
the heap in TID ranges of 16 pages, because without an index on
released_at a `LIMIT n` delete plans as a sequential scan from page 0 that
gets slower as the head of the heap empties (production EXPLAIN). Each
statement selects its rows FOR UPDATE SKIP LOCKED, so a row a request holds
is skipped rather than waited on, and deletes them by `ctid = ANY(ARRAY(...))`
so the delete is always a TID scan. A tick stops at 400 rows, 128 pages or
250 ms, which drains the backlog over about three days at five directors.

* chore(relay): move US cells c32 and c33 to the general same-cap list after promotion (#25367)

Both were promoted to general on 2026-10-01 (selector 344 shows them general),
but the same-cap job still classed them migration-only. Rollback mode on either
would isolate (general -> migration-only) before its no-op check failed, demoting
a live cell. They stay out of the fleet pool list (pool 10, not 16).

* Support modern Qoder commands and verify authenticated resume

Start and resume Qoder through the existing execution-host selector when only the documented qoder command exists. Preserve legacy qodercli preference, explicit commands, quoting and session identity; disconnected SSH execution refuses without local fallback.

Mobile history uses command-at-create only with the optional owned-create capability and an existing stable mutation identity. Reconcile authoritative execution-host inventory before retrying creation, adopt the same surviving operation, preserve WSL/incarnation metadata and restore only missing original launch metadata. Changed retry settings cannot replace original capture. Bounded evidence expires after 15 minutes; unavailable inventory or original evidence refuses recovery and leaves surviving execution untouched. Authoritative inventory proving absence preserves the existing recreation behavior; this is not a durable exactly-once ledger for completed one-shot side effects. Older hosts retain the acknowledged create-then-send path.

Scope mobile launch authority to the current committed host/client generation, and recheck operation ownership after asynchronous preparation before later sends. Retire the mutation once the host acknowledges the resume; later ownership changes stop navigation without reporting a completed resume as failed or reusing a cached legacy pane. Preserve genuinely interrupted mutation identity. Preserve current-main OpenCode validation and merged Pi/Cursor behavior. Correct unchanged-main editor test fixtures to their production insertion-range and store contracts while retaining original assertions and production behavior.

Conservative positional process recognition and existing folder-history matching-worktree limitations remain documented.

* fix(relay): retain confirm results for a week and audit events for 90 days (#25353)

* fix(relay): retain confirm results for a week and audit events for 90 days

relay_confirm_results (8.3M rows, 5.8 GB) and relay_audit_events (8.4M
rows, 3.6 GB) were never deleted. The director's credential cleanup now
reaps both after its existing passes:

- Confirm results older than 7 days. The only reader replays a stored
  result for a retry of the same request on the same connection basis; a
  different basis is already refused as a tuple mismatch. committed_at has
  no index, so this uses the TID-window reaper from the reservation prune,
  capped at 250 rows a tick (the 7.4M-row backlog drains over 2-3 days).
- Audit events older than 90 days, ordered by `at` so the batch walks
  relay_audit_events_at. Nothing in the relay reads them back. The oldest
  row is from 2026-07-14, so this deletes nothing until 2026-10-12.

reapBatch now deletes by `ctid = ANY(ARRAY(...))` on Postgres: with
`ctid IN (...)` the planner can choose a hash join over a sequential scan
of the whole table.

* refactor(relay): stop creating three tables nothing writes (#25354)

* refactor(relay): stop creating three tables nothing writes

relay_confirmable_splices, relay_cell_drain_attempts and
relay_migration_leases are created at every boot and referenced nowhere
else on main except tests. In production all three hold 0 rows and
pg_stat_user_tables shows 0 inserts, 0 sequential and 0 index scans since
the 2026-09-28 stats reset.

This removes them from the schema and the transaction-phase table, and
drops the test references. It does not drop them: an older image still
runs CREATE TABLE IF NOT EXISTS at boot, and a drop racing that create can
fail the older boot's schema step. A follow-up can drop them once no image
that creates them can be rolled back to.

Unknown Codex models now accept the full known effort vocabulary; unknown
effort names are still refused.

* fix(mobile): honour the desktop pinned-worktree placement setting (#25301)

* fix(mobile): honour the desktop pinned-worktree placement setting

Mobile always kept pinned rows in their groups as well as in Pinned. Desktop's
showPinnedWorktreesInGroups (default off) shows them only in Pinned. Read that
setting with its own settings.get operation, refreshed with the list's view
settings, and leave host and device-local pins out of their groups unless it
is on.

* fix(mobile): keep lineage children with a pinned parent

Under single-location a pinned parent left its group while its unpinned child
stayed behind as a root. Visible descendants now follow a pinned ancestor into
Pinned, nested under it, as on desktop. Drop the inert host-id half of the
pinned-policy stale-reply guard; a host switch replaces the client.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* refactor(mobile): fold pinned placement into the desktop view-settings sync

One "sync from desktop" callback now also reads settings.get for pinned
placement, unawaited so a slow read never holds the ui.get merge; the separate
callback and its plumbing are gone. Re-record the three host.view-settings
goldens, which gain only that settings.get send. The pin expansion walks the
lineage children index the renderer now shares, over visible rows only.

* refactor(mobile): one stale-reply rule for the desktop view-settings sync

Both reads in syncViewSettingsFromDesktop now drop a reply only when the client
was replaced; the host-id half compared a captured value with itself. Pin the
no-wait invariant: the ui.get merge applies while settings.get never answers.

Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb

* fix(mobile): follow a pin through rows hidden by search

Desktop's Pinned section walks lineage over every worktree and keeps the
visible descendants, so a grandchild still follows a pinned root when search
hides the middle row. Mobile walked visible rows only and left it in its group.
Build the children index from the unfiltered list; membership stays visible-only.
Drop the hostId arg the view-settings sync no longer reads. Pinned-lineage
tests move to their own file to stay under max-lines.

* refactor(mobile): read pinned placement in its own hook

The placement read was folded into the desktop view-settings sync, so that
callback juggled an awaited and an unawaited read and three goldens recorded a
settings.get that never answers. useHostShowPinnedInGroups now owns the setting
and the catalog refreshes it beside the view-settings sync on connect, focus and
mount; the sync, screen state and goldens are back to main.

The reader returns desktop's boolean, as its siblings do, so transport no longer
imports a worktree type and the two-literal policy union is gone. makeSection
always applies lineage, the pinned walk is a Set worklist, and the lineage
children index drops a set that duplicated its map's keys.

* fix(mobile): key pinned placement to the client that reported it

The host screen is reused across hosts, so the previous host's "show in groups"
value survived a switch until the new read landed, or for good if it failed.
The setting now carries the client that reported it and counts only for that
client, which also makes a late reply from a replaced client inert and drops
the clientRef plumbing.

* fix(mobile): drop a replaced client's late placement reply

Keying the value to its client hid a previous host's value but still let that
host's late reply overwrite the current host's, reverting the list to the
default until the next refresh. Restore the clientRef write guard; the client
key still covers the effect-long window before clientRef follows a switch.

* refactor(mobile): treat pinned placement like the screen's other host state

The placement hook kept its own host-switch handling (a client-keyed value plus
a clientRef guard) beside the screen's existing one. showPinnedInGroups now
lives in HostScreenState, resets with the other host-scoped values in
useHostScreenIdentity, and is read in the catalog refresh behind the same
clientRef check as the catalog fetch. The hook and the catalog argument go.

* feat(relay): declare Asia spare cell c34 as migration-only (#25336)

Adds a sixth asia-east2 cell at the C31 shape (cap 3000, 6000 request
units, pool 16, e2-standard-4) in asia-east2-c, pinned to the f30b5cb1
cell image. It gets its own topology and registration wave but no
promotion wave, so the admission script and workflow refuse to promote
it; it stays a migration-only landing zone and out of the fleet pool list.

* fix(activity): keep code blocks in row previews from rendering as scroll boxes (#25410)

The activity row previews the agent's last reply with the compact markdown
renderer, which draws fenced code blocks and tables as their own scrollable
boxes. Those boxes escaped the row's line clamp, so a reply with a code block
put a tall grey box with scrollbars in the middle of the list.

Row-scoped overrides now flatten code blocks and tables into plain wrapping
text, so the existing clamp cuts them like any other line. Other markdown
surfaces are unchanged.

* fix(native-chat): show a reply cut off by an Orca crash or quit like a finished turn, with one explanation (#25043)

* fix(native-chat): read a crash-cut reply like a finished turn, with one explanation

A reply that an Orca crash or restart cut off said it failed three times: the
turn bar read "Failed after N", the chat's notice row said Claude stopped, and
the sidebar dot stayed red after the chat was read.

The turn bar now reads "Worked for N" for a proven crash/restart cut, the
notice row stays the one explanation, and the sidebar card's dot and agent
rows read failed only until the user has visited the chat (the same
acknowledgement that un-bolds the row), then read done. A failure, a user's
Stop, a replaced turn and an unconfirmed end keep their labels. The stored
outcome is unchanged.

* fix(native-chat): explain a turn a quit or eviction cut, once

A turn cut off by quitting Orca, an idle eviction or a teardown recorded the
same outcome as a crash-cut turn but wrote no notice row, so with the turn bar
now reading "Worked for N" nothing in the chat said it stopped.

The host stop's settle now writes the existing providerExited notice for the
latest turn when it ends as news (no person's Stop decided it): in the same
write as the host's own turn end, or right after the adapter's. It is keyed by
the turn, and skipped when an error row already explains that turn, so a retry
or an earlier exit row never leaves two.

* test(native-chat): narrow the turn scope and add the seen map in the crash-cut tests

* fix(native-chat): derive a cut turn's one notice on read instead of writing it at stop time

A turn cut short when the agent stopped without anyone asking now reads
"Worked for N", so it needs a row saying it stopped. Writing that row only on
the quit and eviction paths missed journals written before this change, a quit
that died between its drain and its settle, and any future stop cause.

The transcript now derives it from the journal on desktop and phone alike: a
root turn that ended interrupted with no verdict and no row about the stop
gets one notice in the provider-exit row's words. A stored exit row, matched by
its exit fact or its writer's identity rather than its tone, stays the
explanation, and so does the restart continuation's own outcome note, so a
refused resume says it once. The host's stop path is back to what it was.

* fix(sidebar): read a cut-short turn's red mark from its acknowledgement on every surface

A turn cut short with nobody asking reads failed only until the user has seen
it. The previous revision passed an optional "seen" flag to each caller, so any
surface that did not pass it, the chat's own tab dot among them, stayed red
beside a sidebar that read Done.

The verdict's display now takes the acknowledgement as part of what it reads:
the entry's stateStartedAt beside the time the user last acknowledged it, both
required, judged by one shared rule. Each surface joins it once where it builds
its rows: the sidebar's agent rows (and so the notes send menu), the workspace
card summary, the terminal tab bar, Cmd-J recent rows, and Activity threads.
Failures, Stops, replaced turns and unproven ends keep their marks as before;
the phone, which has no acknowledgement record, keeps the unseen reading.

* refactor(attention): use the one acknowledgement rule where it was copied

Auto-acknowledgement, the Activity unread count, dashboard row buckets and
notification acknowledgement each spelled the same "acknowledged at or after
the current state began" comparison; they now call the shared rule.

* test(mobile): type the cut-turn notice test's client and hook holder

* test: pin an older host's exit row by its writer and the sidebar rows' acknowledgement join

* test(sidebar): re-read the card and the tab when only an acknowledgement changes

* fix(native-chat): keep a cut turn's notice through a resume that carries on

A resume after a quit writes its "asked this agent to continue" note after its
own message, so counting that note as the cut's explanation removed the notice
once the resume went on, and made it flash away under automatic resume. Only the
notes that say the chat was not carried on (refused, not connected, not
confirmed) stand in for the notice now.

A row about the whole conversation now explains a cut turn only when no other
turn lies between them, and a failed start's row, which is about a start, never
does. The host writers and the rule share the row identity prefixes, with the
contract that a new row explaining a stop carries the provider-exited fact or
one of them.

* fix(sidebar): judge a cut as seen by the main agent's clock when a subagent holds the row

A subagent can keep a row working after its main agent was cut, and the row's
clock then predates the cut, so a look at the working chat counted as having
seen the cut and no red mark showed. The mark now compares the acknowledgement
with the later of the row's and the main agent's clocks; auto-acknowledgement of
the chat on screen reads the same clock, and its stamp covers it, so looking at
the chat still clears the mark. Bold rows, dashboard buckets, notifications and
unread counts keep the row's clock.

* fix(native-chat): tie a conversation-wide exit row to a cut only with no message sent since

A send after a quit's cut whose new agent died before its turn opened leaves a
provider-exit row about the whole conversation. That row is about the send,
not the earlier cut, so the cut kept no explanation. An exit row now explains
a preceding cut only when no message was sent in between; the restart notes,
which follow the continuation's own message, still need only no turn between.

The notes that say a resume did not carry the chat on are now told apart from
the continued note by their tone ('error' or 'warning'), which every host that
wrote them has set, instead of by their words.

* fix(native-chat): keep an owner's proven death the explanation of its cut after a send

A chat read before the startup reconcile settles its cut turn unverifiable;
if the user then sends a message, the reconcile proves the old agent dead and
writes its row about the conversation after that message. The row names the
old owner's death, never the send, so a message since no longer detaches it
from the cut. Only a provider-exit row, which a later start can write, still
needs no message sent since.

* test(sidebar): give the activity-status store mock the acknowledgement map

The card summary now reads acknowledgedAgentsByPaneKey; this test's hand-built
store state lacked it, so every summary read threw.

* refactor: move the seen-gated red mark out of this change

This change now keeps only the cut turn's label and its one derived notice.
The red mark that clears once the user has seen a cut turn moves to its own
change, so each can land alone; until it lands, the sidebar, tab bar, Cmd-J,
Activity and the notes send menu read a cut turn as failed, as before.

* test(native-chat): pin that a restart note after a continuation's turn leaves the cut's notice

* fix(mobile): stop Android from selecting words while the chat transcript scrolls (#22871)

* fix(mobile): stop Android from selecting words while the chat transcript scrolls

On Android every paragraph, heading, quote, code block and table cell in
the native chat transcript was a selectable TextView. Android starts a
word selection, with the magnifier, on a double tap or a long press, and
two flicks in the same spot while scrolling a FlatList register as a
double tap, so scrolling the chat kept selecting words. iOS is unaffected:
its UITextView path arbitrates scroll against selection itself.

Android now renders transcript text without inline selection: one gate in
MarkdownText covers every selectable span, and the user bubble follows
it. A long press on a message opens a sheet with "Copy message" and
"Select text", the latter a screen whose only content is one selectable
Text, so a selection can only start where the user asked for it. The
message row owns that sheet and mounts it only while open. iOS and web
keep their inline selection and get no long-press handler.

Verified on a Pixel 10 Pro Fold (Android 17): an adb double tap on the
transcript selects nothing, the same double tap inside "Select text"
selects a word, tool rows inside the bubble still expand on tap, and the
long press opens the sheet.

* fix(mobile): scope the Android selection gate to the transcript and route span long presses

Review follow-ups on #22871:

- The gate now applies only where `rangeSelectable` is passed (the chat
  transcript). Task comments and file previews keep their selectable text
  on Android as before.
- On the Android transcript, spans that take taps (links, file paths)
  also take the row's long press, so a link under the finger no longer
  swallows the copy/select sheet.
- Copied text keeps its whitespace; only whitespace-only blocks are dropped.
- The Android markdown test compares `String(node.type)` instead of a
  type assertion, which the changed-code quality gate rejects.

* fix(mobile): route long presses on Markdown images to the row on Android

An image block is a Pressable of its own, so on the Android transcript it
now carries the row's onLongPress like tappable spans do; a long press on
an image opens the copy/select sheet instead of being swallowed. Test
extended with an image block.

* test(mobile): pin the Android long press from a chat row to its actions sheet

The existing row suite runs as iOS, where the bubble has no long press.
This one runs as Android: the bubble's long press mounts the actions
sheet with the message, the markdown receives the same handler, closing
unmounts the sheet, and the user bubble carries no inline selection.

* fix(mobile): preserve Android message selection while replies stream

* feat(jira): pick the assignee when creating an issue — Automatic, me, or anyone (#24376)

* feat(jira): pick the assignee when creating an issue — Automatic, me, or anyone

The new-issue dialog gains an Assignee picker: Automatic (Jira applies the
project's default assignee), one-click "Assign to me" resolved from the
target site's stored identity, or any user via search. The selection resets
with the custom field values on project/type switches, since account ids
are site-scoped.

Creates now also send userFieldKeys, so the host shapes user-typed values
into the {accountId}/{name} refs Jira requires — previously the dialog
never passed them and user create fields were sent as bare strings. Keys
are only named when a value is present, keeping older remote hosts without
the user-fields capability working for assignee-less creates.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* fix(jira): address assignee review — project-scoped assignable search, per-site picker remount, keep assignee across type changes

- Search the create dialog's assignee picker against /user/assignable/search?project=…
  (new listAssignableUsersForProject, IPC split into jira-user-search.ts for the
  max-lines budget); remote environment targets fall back to the existing
  site-wide search since older hosts have no such RPC
- Remount the picker per target project so cached results from the previous
  project or site cannot be selected after a switch
- Reset the picked assignee on project selection (account ids are site-scoped)
  instead of on every create-fields reload, so issue-type changes keep it
- Hide the assignee field and omit it from the payload when the target create
  screen does not accept an assignee — Jira rejects fields absent from the screen

* refactor(terminal): one commit module for terminal topology closes, with a boundary check (#25329)

* refactor(terminal): move the topology revision and leaf-lookup helpers into terminal-topology

advanceTerminalTopologyRevision, findTerminalTabIdForLeaf and
hasHostAuthoritativeTerminalMembership move verbatim from the renderer-save
membership rebase into persistence/terminal-topology, the home of the commit
boundary. Importers are repointed; no behavior change.

* test(terminal): test-only guard for topology writes outside the commit boundary

The three session sinks now publish through one commitWorkspaceSessionPartition
helper, which hands the prior and published partition to the topology write
guard. Production never arms the guard, so each sink pays one global lookup.

The unit suite arms it in report mode: a sink write that changes class-(a)
topology (membership, root, bindings, titles, incarnations, sleeping records,
remote session ids, tombstones, default-applied, revision) outside a commit
scope is attributed to its writer's file by stack, and fails the test unless
the writer is on the unrouted-writers allowlist that later routing PRs shrink.
Renderer saves and test seeding are exempt. Deep-freeze is available but stays
off suite-wide until the in-place writers return new sessions.

terminal-topology-commit.ts is the boundary for class-(a) terminal topology.
bindLeaf forwards to persistPtyBinding, whose write now runs in a commit
scope; the spawn commits and the relay reattach bind through it. closeLeaf and
closeTab wrap the existing close mutation in a commit scope and one
persistence.terminal-topology span (kind, outcome, refusal reason; no ids),
and the runtime close goes through them. Session output is unchanged: tests
compare it byte for byte with the old writers for local, ssh: and folder
workspaces.

* chore(terminal): drop an unused lint suppression from the topology write guard

* fix(terminal): attribute topology guard writers relative to the repo root

The guard read a frame's file through its last /src/ segment, so a test under
tests/ (folder-upgrade-identity-persistence.unit.test.ts) had no source frame
and failed as an unknown writer. Frames are now taken relative to the repo
root the setup passes in, tests/ counts as test seeding, Windows backslashes
are normalized before the node_modules skip, and nested src/ paths keep their
full path. The two runtime funnel files skip only their funnel function, so
another writer in them still shows. The R9 allowlist key names the file whose
frame actually writes. The class-(a) diff and the attribution move into their
own files; the stack limit is restored in a finally.

* refactor(terminal): drop bindLeaf until binding reaches a sink; add the boundary ratchet

bindLeaf and the commit scope inside persistPtyBinding changed nothing: the
binding write never reaches a session sink, and a scope inside the Store method
would have admitted every direct caller once it did. Both return in B1-4; the
spawn commits and the relay reattach call persistPtyBinding directly again.

The runtime close now calls one closeLeafOrTab entry, so its callbacks keep
their contextual types. A census test is the primary enforcement: only
persistence/terminal-topology and the callers it lists may call
persistPtyBinding, the session setters or the three sinks, and every
unrouted-writer allowlist entry must name an existing file.

* fix(test): resolve the topology guard's repo root without the global URL

Under happy-dom the global URL is not Node's, so fileURLToPath(new URL(...))
threw in the setup file and failed every happy-dom test file.

* refactor(terminal): drop the runtime topology write guard; the boundary ratchet enforces

The AST boundary ratchet is the enforcement for B1. The stack-attributed
runtime guard, its class-(a) diff, the unrouted-writer allowlist, the vitest
setup and the freeze option are removed; it saw two writers in the whole unit
suite and its real value starts only once binding reaches a sink (B1-4).

Also: one closeLeafOrTab wraps the close in the span (no per-kind copies or
narrowed types), the span has one finish like persistence.pty-binding, the
sink helper is publishWorkspaceSessionPartition (it publishes; the commit
boundary is the module), the ratchet drops the private publishSession row and
checks that every listed caller file exists, and the close comparison keeps
its two meaningful cases with span cases chosen by name.

* refactor(terminal): trim the B1-1 commit module and ratchet to what they enforce

- Point the acknowledged-tab-retirement audit fixture at the moved
  advanceTerminalTopologyRevision; its old import no longer resolved.
- Drop publishWorkspaceSessionPartition: it was the removed guard's
  interception point, so the three session sinks return to origin/main.
- One traced(kind, mutate) wrapper in the commit file replaces the span
  factory; closeLeafOrTab is one call.
- The ratchet walks src/main with the shared scanSourceTree, drops the
  loading-store-internal rows and the redundant file-exists test; exact-set
  equality already fails on a missing file.
- The commit test is a pure unit test of the span outcomes: no Store
  harness, electron mock or self-comparing close.

* refactor(terminal): census the runtime session controller's write and drop stage ids from comments

The controller's setter was named set, which the boundary census could not
list without matching every Map.set, so a new OrcaRuntime mixin could write
sessions through it unseen. Rename it setForWorktree and census it.
Comments now describe state instead of citing plan stage ids.

* refactor(terminal): census writer references and trace refusals by callback

- traced() takes refusalOf instead of assuming an Error refusal, and only
  mutate() sits in the try, so a span outcome of threw means the write threw.
- The boundary ratchet counts references, not just direct calls: non-null
  calls, bracket keys, aliases, destructures, .call/.bind and parenthesized
  callees all count; declared names and type positions do not.
- Census terminalSurfaceCloseMutation (boundary-only) and the partition sinks
  setLocalWorkspaceSession / setHostWorkspaceSession.

* test(terminal): count writer uses in extends clauses and instantiations, skip type-only imports and local declarations

The census skipped ExpressionWithTypeArguments as a type, which also holds
`extends f(x)` and `x<T>` value expressions. Type-only import/export
specifiers and declared names (variables, parameters, accessors, enum
members) no longer count as uses. The audit fixture is listed in the table
instead of a separate exemption.

* test(terminal): count quoted and assignment-pattern destructures of layout writers

* test(terminal): count every mention of a layout writer except its definition

Telling definitions from uses per syntax kind kept missing nested and
for-of destructures. Exempt only the writer's own function or class-member
definition; any other mention (including object-literal keys) counts, so the
census errs toward a loud false alarm rather than a silent miss. Quoted names
count only in member-name position.

* test(terminal): count every string literal naming a layout writer

Member-name positions missed wrapped keys like store[('name')] and
store['name' as const]. Counting every string literal outside types is
shorter and errs toward a loud false alarm.

* test(terminal): exempt only class members and functions as writer definitions

Object-literal methods and accessors were exempt while equivalent arrow
properties counted; all object-literal keys now count alike.

* test(terminal): parse files with unicode escapes in the writer census

A name spelled with a \u escape never appears verbatim, so the text
prefilter skipped it.

* test(terminal): parse any file with an escape in the writer census

\x, identity and line-continuation escapes also decode to a writer name
without it appearing verbatim.

* fix(native-chat): a Stop binds only the turn it actually stopped (#24864)

* fix(native-chat): a Stop binds only the turn it actually stopped

A Stop pressed before any turn showed used to claim, at end-write time,
whatever turn the stopped send later opened, even when the Stop stopped
nothing. A turn that then died on its own read as "Interrupted" (your
cancellation) instead of "Failed".

Now a person's Stop that named no turn binds, in memory only, every turn
that ends while the Stop settles, and afterwards only the turn its
interrupt took. The settle ends a still-running stopped turn once. A
relaunch finds nothing in memory, so an unsettled turnless Stop binds no
turn. A Codex Stop whose answered turn does not open within its wait, or
whose send's answer was lost, now answers refused, so the host ends the
child and the turn can never run.

* fix(native-chat): keep the person's queue pause and close binding after a Stop settles

A host stop or eviction with no turn running now defers to a person's
Stop while its queue pause still holds with nothing sent since, read from
rows, so a held card is not handed off on reopen after a Stop that did
nothing or whose kill failed.

A person's close that named no turn opens a settle around its child's
end, so a turn that end cuts reads as theirs.

A press opens its settle only when the latest Stop event is its own or
the one in force it repeats: a late Stop, a card's interrupt or a lost
event row reopens no earlier Stop.

A Codex Stop that cannot reach a turn still able to open says the Stop is
unconfirmed rather than that no turn ran, and a second Stop still reaches
a turn an earlier wait left unopened.

Also drops the unused openedBy plumbing and the unreachable "a written
cancellation stays one" rule, and pins a relaunch after a named Stop.

* fix(native-chat): a Codex Stop agrees on both presses when a turn is still owed, and pin the close's settle

A Codex Stop that waited for a turn Codex answered a send into now answers
"may still open" whenever that turn neither opened nor ended and its send
is still owed, however the wait ended (it ran out, or the thread went
idle). Before, a first press after an idle thread said no turn was
running and kept Codex, while an identical second press ended it.

Adds a test that a person's close the conversation outlives (as /clear
does) closes its settle, so a later turn that ends on its own reads as a
failure.

* test(native-chat): a Stop whose event row failed binds no turn to an earlier Stop

With one ordered journal writer the Stop's event is in the fold when its
write returns, so the press reads whether it owns the latest Stop from the
fold instead of awaiting the write. Pins the case the read must refuse.

* test(native-chat): name the settle, not a stream drain, in the Stop's own-end test

* test(native-chat): a Codex Stop answered before Codex ends the turn reads interrupted throughout

Codex answers an interrupt it took before it sends turn/completed (interrupted):
on TurnAborted the app-server answers pending interrupts, then ends the turn, on
one channel. The test fake did the reverse. It now answers first and ends the
turn on a later read, and the tests that read the turn's end right after a Stop
wait for it.

New end-to-end test through the shipped host, journal and Codex adapter: with
the real order, every end row of the stopped turn reads interrupted by the Stop
(named, unnamed, and a Stop pressed while turn/start was in flight). Breaking the
settle window turns the in-flight case red: the Stop's own end row then has no
verdict, which reads as failed until Codex's end lands.

* fix(native-chat): a Codex Stop interrupts a turn Codex answered but has not opened at once

A Stop that named no turn, made after Codex answered a send but before the turn
opened, used to wait up to 5 s for the turn to open before interrupting, and
ended the Codex process when it didn't. The stated reason, that Codex refuses an
interrupt until it opens the turn, holds only part of the time: with no turn
active, Codex takes an interrupt once its thread runs (turn_interrupt_inner),
and refuses it with -32600 "no active turn to interrupt" before that or once
the turn has ended.

The Stop now sends the interrupt at once. Only on that refusal, while the turn
has neither opened nor ended, does it wait for the turn to open (bounded at
5 s) and send it once more. A turn that ended meanwhile was nothing to stop. One
that never opens, or that an earlier wait already gave up on, fails the Stop,
and the host ends the child as before. Sends still wait for the turn to open
before steering into it.

The test fake models Codex taking an interrupt once the thread runs (run()).

* fix(native-chat): every Codex Stop waits for an answered turn to start, as the first did

A Stop whose interrupt Codex refused as finding no active turn skipped the wait
when an earlier wait, a Stop's or a send's, had already given up on that turn.
Every press now waits its own bound and retries once if the turn starts, so a
turn that opens during a later press is still stopped. Both presses still reach
the same verdict when it never starts.

* fix(native-chat): a Codex Stop that ends the child before any turn opened withdraws its send

A Stop on a Codex turn that was answered but never opened ends the Codex
process. That end settled the send as in doubt (unknown, recovered), and the
client's outbox holds every later send behind a send in doubt until the person
presses Retry, which re-sends the very message they stopped. The chat looked
stuck.

Codex records a prompt only once its turn has started, so a send whose turn
never opened never ran. When the Stop's refusal says so (turnMayOpen), the child
end now settles the unanswered sends as withdrawn, the verdict Codex's own
interrupted-turn end already gives an unechoed send. The flag rides on the owed
wind-down, so a retry after a failed child end withdraws them too. Claude's
child end still leaves its unanswered send in doubt.

* fix(native-chat): derive the withdrawal of a Codex send whose turn never opened

Replaces the flag the Stop carried to the child's end, and its copy on the owed
wind-down, with a reading of the journal at the settlement that lands. A Codex
child's unanswered send is withdrawn when a person's Stop is in force since it
was sent and no turn row ran, or was written, after it; any other end (a turn
that opened, a host's close, a crash, Claude) still leaves it in doubt. A
retried wind-down reads the same rows, so it withdraws the same sends.

* fix(native-chat): keep a send in doubt when a turn was open for it

The derived withdrawal read a turn as open for a send only if it still ran or
was written after the send. A send steered into a running Codex turn whose
interrupt failed met neither once the adapter's end settled that turn ahead of
the host's settle, so it read withdrawn, though Codex drains a steer into the
running turn and may hold it. A turn that ended after the send was handed over
was open for it too: such a send stays in doubt, as before.

Pins that case, and that a send made after the Stop, to a child that then dies
before its turn opens, stays in doubt.

* fix(native-chat): withdraw a Codex send by whether it started its own turn, not by timing

Whether a turn was open for a send was read from end times: a turn that ended
after the send's handover counted. A send made while a Stop ended the turn is
handed over once that turn reads ended, yet Codex's own end for it can arrive
later, so such a send whose own turn never opened read in doubt again, and the
chat's queue held behind it.

The handover already records where the send went: its message joins the turn
running then (a steer) or belongs to no turn (it starts its own). Only a send
that started its own turn, with none opened since, is withdrawn; one that
joined a running turn, or has no recorded place, stays in doubt.

The Codex test fake takes an answered interrupt as Codex does, dropping the
turn before its end arrives.

* fix(native-chat): leave no Stop row when the Stop took back a send that never ran

A Stop on a Codex send whose turn never opened ends the child, and the child's end
takes the send back into the composer. The Stop still wrote "Cancellation
requested." at the conversation level, so with the send gone it sat under the
previous finished turn and read as if that turn had been stopped. A Stop that found
no turn running and whose child end took back every send it found now writes no
row; a Stop of a running turn, or one that leaves a send in doubt, still does.

* fix(native-chat): count a send whose answer was lost when a Stop takes it back

The no-row rule counted only pending sends, but the child's end also takes back a send this process left in doubt when Codex's turn/start answer was lost. That case still wrote "Cancellation requested." under the previous turn. Both now read one predicate, so they cannot drift apart.

* test(native-chat): pin which sends a Stop's child end can take back

A send an earlier process left in doubt is never withdrawn and never holds the row back, and a queued card's send is never counted.

* test(native-chat): read the outbox reconcile from where main moved it

* fix(native-chat): a chat's finished-turn alerts come from the host recorded on its tab, not its workspace id (#25081)

* test(native-chat): a mirrored paired chat carries its host, so a workspace-id collision no longer hides its owner

* fix(native-chat): a chat's finished-turn alerts come from the host stamped on its tab, not its workspace id

* fix(native-chat): the attention bridge reads a chat's owner from the same rule as the chat pane

* fix(native-chat): never delete chat history on read; a chat Orca can't load says why once (#24576)

* fix(native-chat): an older Orca keeps a chat with newer content read-only, and an unreadable annotation costs only itself

A body or lifecycle mutation of a kind this build does not know, inside a row of a known kind,
now latches the chat read-only with every row kept, as a newer row kind or version already does.
It used to read as damage, and the open deleted the journal from that row on.

Each optional field of a body schema now declares what an unparseable value means:
- droppable (an annotation): removed from the row in memory; the chat stays writable;
- must-understand (a prompt's questions, a plan approval's plan, a turn's lifecycle, a goal
  change): the row is unreadable and the chat latches read-only.
Only a required field that fails is damage, repaired as before. A test holds every optional
field reachable from a body schema to a policy; the known body kinds are read off the schema.

Prompt options and questions no longer reject a key this build does not know, which deleted the
journal from that row on. The context-usage drop is now one case of the droppable rule.

* feat(native-chat): a chat an older Orca keeps read-only says so before a send is refused

A chat a newer Orca wrote opens read-only, and until now nothing said so: the person found out
when a send failed with "Chats were saved by a newer Orca". The host now names the reason on
every whole history page it serves (`page.readOnly: 'written-by-newer-orca'`: hydration, history
and catch-up resets), the shared client reducer keeps it from the latest whole page, and the
desktop status strip and the phone's composer area say "This chat was saved by a newer Orca, so
it's read-only here. Update Orca to continue this chat."

Every read-only latch the host has is a newer Orca's (its database, a row version, a row kind, a
body kind or must-understand fact), so the reason is derived from the journal's latch, not stored.
The field is optional: older clients ignore it (cross-version test against the newest release's
reducer), and older hosts never send it, so a new client against one says nothing, as today. A
reason this client does not know shows nothing rather than words that may be wrong.

The window-merge helpers move out of the client reducer into their own module.

* fix(native-chat): only a newer build's value goes read-only; damage repairs as before

An older Orca keeps a chat read-only only on evidence a newer build wrote it: a value outside a
closed set this build knows (a body kind, a nested discriminant or literal, a mutation kind), read
off zod's issues. That evidence wins over damage beside it. Anything else that fails (a wrong type,
a missing field, a bad optional value) is damage, repaired as before, so damage no longer freezes
a chat behind an "update Orca" it cannot fix. Drops the per-field droppable/must-understand
policy. A lifecycle mutation's kind is decided before its item id, so a newer kind without one is
kept. The context-usage drop is unchanged from main.

* fix(native-chat): a read-only chat locks its composer and says why there

Removes the separate read-only line (desktop status strip, phone notice component). The host's
`readOnly` on whole pages now feeds the existing composer lock instead: desktop disables the
composer with "Saved by a newer Orca. Update Orca to continue this chat." as its placeholder, and
the phone adds a 'read-only' input-lock reason with the same words. A read-only chat shows no
prompt card it would refuse; the draft stays in the composer. The phone's send-failure line is
back exactly as on main.

* fix(native-chat): a read-only chat pages back through its history

A read-only journal answered every history request with a reset, so a chat this PR now keeps
read-only more often could show only its newest page. Backward reads now serve the snapshot the
open folded, as the first page already does; a forward read of rows still resets.

* test(native-chat): an unknown key in a question entry is read and kept

* test(mobile): the read-only overlay test typechecks

* chore(native-chat): satisfy the changed-code gate in admission and the read-only overlay test

* fix(native-chat): a new value inside a known block or goal arm reads as a newer build's

The open fallback arm of the block and goal unions now aborts, so zod reports the known arm's own
failure instead of only the fallback's; a future closed set there reads unreadable, damage there
still repairs. The schema headers name the context-usage exception and say a new open-string
value must be safe for every older build (rewind keeps only known states; pages carry no row
version).

* fix(native-chat): a read-only chat reconnects for a whole page, so an updated host unlocks it

The client keeps `readOnly` until a whole page replaces it, but reconnected at its cursor and got
only batches, so a desktop attached to a host updated in place stayed locked with "Update Orca".
While it holds the latch it now subscribes without a cursor; the snapshot re-derives the state on
any host version. The phone already subscribes without one.

* fix(native-chat): every desktop write control follows the one read-only fact

The structured session's transport state derives one fact from the page's `readOnly`: the words
for why the host refuses writes. Every write control reads it. While it holds, the chat has no
turn and no work, as the host projects it, so the working row and Stop go away; a pending prompt
stays shown above the composer with its card disabled; queued cards' Send now, Delete and Edit,
the queue's Resume, the goal banner's actions, the model and option pickers, dictation and
background-task Stop are disabled or withheld. The composer placeholder stays the one place the
reason is said. `lockReason` now locks the composer by itself.

* fix(mobile): every phone write control follows the one read-only fact

The phone session derives one fact from the page's `readOnly`, the words for why the host refuses
writes, and every write control reads it: no turn or work while it holds, so no Stop; the pending
prompt stays shown with its card disabled; queued cards and Resume are inert; the model and option
pickers stay shut; the composer field is not editable, so its placeholder keeps saying why, and the
lock applies at once instead of after the transport lock's settle.

* test(native-chat): the newest release hydrates a read-only chat and scrolls back through it

* test(native-chat): a read-only chat reads idle even with a send its provider never answered

* test(native-chat): composer lock test without type assertions

* fix(native-chat): round-3 read-only fixes

- An old /model or option request no longer reopens its picker when a read-only chat unlocks: the
  menu is keyed by the request alone, and a lock only keeps it from mounting open.
- A disabled question card still steps through its questions; only answering is locked.
- A failed send's notice in a read-only chat says only that the message was not sent, with no
  Retry: the composer already says why, and no retry can land. Its wiring moves into
  useStructuredAgentSessionDeliveryNotices.
- The host's background-task stop flags stand; the client no longer overrides them.
- The view reads the read-only fact through one local flag.
- The schema header says what an older build's rewind does with each open string.

* test(native-chat): count picker mounts without an effect

* fix(native-chat): read-only keeps other failures' words and shuts open option menus

- In a read-only chat, only a send the newer-Orca refusal stopped is shortened to "Your message
  was not sent."; any other saved failure keeps its own words, and none offers a Retry.
- A model or option menu open when the lock lands has its items disabled, so it cannot send a
  change the host would refuse.

* test(native-chat): lock-lands picker test uses a typed surface

* fix(native-chat): a locked composer draws its reason

The editor's placeholder used the default that draws nothing while the editor is not editable, so
a read-only chat's composer was empty and its reason lived only in the aria-label. The placeholder
now draws while disabled, and its words are empty unless the composer is locked with a reason, so
every other disabled composer (a pending prompt, no terminal) looks as before.

* fix(native-chat): sync the locked-placeholder flag in an effect, not during render

* fix(native-chat): a read-only chat is not offered for resume or counted as failed to resume

After a relaunch, a chat whose journal this build keeps read-only (a newer Orca's) was listed in
"Resume interrupted chats?", failed with "Orca couldn't resume this chat. Open it to continue
manually.", and left a status-bar "N chats failed to resume" that never cleared, since nothing can
continue a chat this build cannot write. The resume set now skips such a chat after the checks
that end an offer (fork, moved on), so the offer is kept, not spent, and an updated Orca offers it
again; the failure ledger keeps an already-filed failure for it but does not show it. Both read
the chat's open journal, which listing and acting open first.

* fix(native-chat): a refused resume continuation keeps the refusal's reason

A send refused while continuing a chat after a restart was filed with its code alone, so a newer
Orca's refusal lost its `journalWrittenByNewerOrca` reason. The continuation now carries the whole
refusal, as a refusal from the agent's start already did, so the filed failure keeps it.

* fix(native-chat): a newer Orca's chat keeps its resume offer however it is met

- A newer Orca's whole database counts as read-only for resume, so a chat whose journal cannot
  be opened at all (a table the newer schema changed) is not offered, run or counted either.
- The checks made right before sending no longer skip read-only chats: turning one away there was
  read as the user having moved on and deleted the offer. Its send is refused instead.
- Settling a resume files nothing for a newer Orca's refusal; the existing rollback reopens the
  offer for an updated Orca.
- The continuation records the refusal as a reference, without the wire prose.

* chore(native-chat): one import of the session wire types in the continuation

* docs(native-chat): resume and read-only comments match the current rule

* test(native-chat): a closed set of a journal row cannot change without the row version

The test walks the body schema and the row and mutation kind tables, collects every closed set (a
row kind, a mutation kind, each enum, literal or discriminant), and compares them with a snapshot
recorded beside the row version. A new value makes older builds go read-only, so it fails until
the reader ships first or `v` is bumped and the snapshot updated. Tags a catch-all arm accepts as
any string (block types, goal states) are listed apart: older builds read a new one as-is.

* feat(native-chat): a body or plan subject of a newer kind is kept and the chat stays writable

An item body kind and an approval subject kind this build does not know now read through the
same catch-all blocks and goal states use (`openDiscriminatedUnion`), instead of making the chat
read-only. The item is kept, drawn by nobody, and ignored by everything that reads items (turns,
prompts, status); a rewind carries it as it was, kept by its place like every other row. An
approval whose subject this build cannot draw shows its `detail`, which Orca's writers fill with
the subject's text. A sent message of a kind this build does not know stays a newer build's.

* fix(native-chat): rewind narrows a retained body by its kind before normalizing it

* fix(native-chat): one chat that cannot open no longer stops the startup restore of the rest

* fix(native-chat): a damaged chat fails to load and nothing is deleted

A row this build cannot parse, a gap, or an epoch without its first row used to
be repaired on open: every row from the damage on was deleted and a rebuild from
the provider transcript was attempted. The open now fails through one refusal
(failLoadOnJournalDamage, journalCorrupt), every row stays, and a damaged
per-chat file is kept whole and never copied. A newer build's row still wins
and keeps the chat read-only. The body classifier for closed-set values, the
repair marker and disclosure, and journal recovery from the transcript go.

* chore(native-chat): no reset or adapter left on the open's fixtures

* feat(native-chat): an approval of a newer Orca's subject kind can only be cancelled

Desktop and phone show its detail and the line "This request needs a newer
version of Orca.", disable every answer, and keep the card's cancel, which ends
the turn. The chat stays writable.

* test(native-chat): the closed-set guard says a missed version bump fails older builds' load

* test(native-chat): the closed-set guard names what a missed version bump does

* fix(native-chat): a row the reader rejects is never written, and a chat that cannot load keeps its tab

Every journal insert reads its serialized row back with the reader inside the
write's transaction and refuses one it rejects, so Orca's own writer can no
longer leave a chat that fails to load. A restored chat whose open fails keeps
its tab and says why when opened. An epoch named with no rows is founded afresh
again, deleting nothing. The at-rest test now expects a damaged chat to be
refused; the replay gate keeps its 2026-09-11 evidence as it was run.

* fix(native-chat): a newer Orca's approval subject is carried as it was, and its card cancels with or without a turn

The approval subject's type is open, so code that reads a plan narrows first; the
host's prompt bounding carries an unknown subject instead of rebuilding it as a
plan, which threw in every start's stale settlement. A Codex rewind keeps a
newer Orca's item in its place. A whitespace-only tag is damage. The card's
cancel reaches the host without a running turn on hosts that take that. A
provider row the reader rejects ends its turn as interrupted and the next send
works. A guard fails if an approval subject kind is added before clients can be
gated (STA-9262).

* fix(native-chat): a card's cancel sends nothing without a turn again, and rewind keeps a newer row after any held row

The host's cancel request has to name a turn on every version, so the turnless
prompt cancel is reverted on desktop and phone. The rewind merge moves its anchor
for every row the provider still holds, so a newer Orca's row stays after one
whose kind this build does not know.

* fix(native-chat): a card this build cannot answer leaves the composer open, and a send starts a turn

An approval of a subject kind this build cannot draw, raised by a newer host's background agent
while no turn runs, left nothing to press: its answers are disabled, its cancel needs a turn, and
the desktop composer gave the card its slot. A send the host queues waits behind any pending
prompt, so even the phone's open composer only queued.

While every pending prompt is one this build cannot answer, the desktop composer stays open, and
desktop and phone send without asking to queue: the send starts a turn, and the card's cancel then
settles it. A chat a dead run left is unaffected: opening it already cancels those prompts.

* feat(native-chat): a chat a newer Orca saved fails to load and says to update, with nothing to send into

Opening a chat a newer Orca saved (a row kind, batch-change kind or sent-message kind this build does
not know, a newer row version, or a newer history store) used to open it read-only: the history
shown, the composer locked with a reason, every control greyed. Now it fails the load, like a
damaged chat, with its own words: "This chat was saved by a newer Orca. Update Orca to open it."
Every row is kept. The read is final, so the pane stops retrying; reopening the tab reads again.

A chat whose load failed for good (damaged, or a newer Orca's) offers no composer under the error,
on desktop and on the phone, so the failure is said once and no send can be refused a second time.

A restart offer for a newer Orca's chat is spent without a word: no failure filed, nothing counted.

Removed with the read-only mode: the journal's read-only latch and every check of it, the history
page's readOnly field (never released), the cursorless reconnect, read-only paging, the composer
lock and placeholder, the greyed controls, and the resume exclusion.

* test(native-chat): a newer Orca's records open no chat, and a status fake carries its submissions

* test(native-chat): the status fake's cast says what the feed reads

* fix(native-chat): a chat's read that failed for good takes the whole pane, over a loaded transcript too

* test(native-chat): the final-read-failure test names its reasons

* fix(native-chat): a newer Orca's chat keeps its restart offer, and its refused load is logged once

* refactor(native-chat): the newer-Orca chats a restart listing skips live beside the candidate reader

* fix(native-chat): a refused chat load keeps where it failed, so the log names it and a new reason logs again

* chore(native-chat): the reducer's window merge back where main has it, and comments say a newer Orca's chat fails to load

* test(agent-hooks): the rename test's journal fakes carry submissions, as a journal snapshot does

* test(agent-hooks): the rename test's journal fakes say what the status feed reads

* fix(native-chat): Dismiss all ends the restart offers this Orca lists, and keeps a newer Orca's hidden ones

* test(native-chat): a resend against a newer Orca's store answers unknown, and the phone says nothing beside the read's words

This build never opens a chat a newer Orca's database holds, so a resent send id there cannot be
answered from its journal: it answers "outcome unknown", never a refusal and never a made-up
record, with no second delivery and no write. On the phone, a send error left beside a read that
failed for good is not shown; the pane keeps only the read's words.

* fix(codex): stop prompting a Codex restart when only its home changed (#25421)

* fix(codex): stop prompting a Codex restart when only its home changed

A Codex terminal that outlived the move to ~/.codex was blocked behind "This
Codex session is using an outdated configuration" until the user restarted it,
which starts a fresh codex and ends the conversation. That terminal keeps
working on Orca's old Codex home, which is refreshed from ~/.codex, so the
change did not need the user's answer; the prompt also never appeared for
Codex in Git Bash terminals, whose process tree Orca cannot see through.

The restart prompt now covers only an account switch, which the user caused.
The pane record keeps its home route, which the retained-home refresh and the
shared-server check still read; only the prompt and the custom-home downgrade
that existed to keep it from guessing are gone.

* refactor(codex): drop what the home-route prompt left behind

- Record a pane's own CODEX_HOME override as-is. The filter that kept only
  overrides Orca could re-derive existed for the removed route comparison;
  its one remaining reader, the shared-server check, returns null for the
  shared-home route those panes record either way.
- Treat custom-home like shared-home in resolveCodexPaneHome: the removed
  downgrade only wrote it without an override, so it never named a home.
- Inline the restart notice key; its route/account prefix was its only job.
- Delete the two pane-local override tests, including a POSIX-only one that
  still expected custom-home and would have failed on Linux and macOS CI.
- Cover the account recheck branches the deleted route-recheck file was the
  last to exercise: main reporting a pane current, and main not answering.

* refactor(codex): retire custom-home and the last re-check helpers

- Read an older build's custom-home record as shared-home, which it always
  was, and drop custom-home from the route type and every check.
- Delete shellStartupCodexHomeOverrideMatches and its comparison helper;
  nothing re-checks a recorded override any more.
- Build the pane launch record in one return: the route is always set, and
  only a resumed launch differs, in how it picks the account.
- Drop the restart dialog's notice key; its focus effect now depends on the
  pane and both account labels directly.
- Give the account recheck test a typed window stub, so CI's type-assertion
  gate passes, and remove timing entries for deleted test files.

* fix(codex): drop the removed dialog strings main added to es.json

* refactor(codex): stop recording a pane's custom CODEX_HOME

The pane record kept a pane's CODEX_HOME override so the removed route
prompt could re-check it later. Its one other reader, the shared-server
check, only looked at it for a real-home pane, and a custom CODEX_HOME
always routes a pane to Orca's mirror, so it was never used.

Drop both record fields, their validators, equality checks and spawn
plumbing. getCustomCodexHomeOverrideForLaunch folds into the existing
hasCustomCodexHomeOverrideForLaunch, and real-home resolves to ~/.codex.
Records from older builds still parse; the parser keeps only known keys.

The fish test's decoy no longer sets CODEX_HOME, so the boolean check
still fails if the launch env XDG_CONFIG_HOME is ignored.

* test(codex): drop setup the yes/no CODEX_HOME checks no longer need

The paired web client has no Jira preload, so window.api.jira.status()

Parse the status reply at the runtime-client boundary so every reader
gets a well-formed JiraConnectionStatus.

* feat(agent-launch): keep long prompts off the launch line and paste them after readiness (step 1 of 7) (#24257)

* feat(agent-launch): host-side prompt delivery for agent.launch

The host's agent.launch typed any launch prompt into the shell as part of the
launch command. A long or multi-line prompt then ran line by line in the
shell, and an agent that never showed readiness or crashed at startup had
nothing guarding where its text went.

agent.launch now carries a prompt on the typed line only when the line stays
one line, control-free and at most 512 bytes; otherwise the agent starts
clean and the host pastes the prompt once the agent's own ready signal fires
(bracketed paste plus its composer marker or a quiet render, read only after
the shell's last hand-off, never while the pane's own shell is proven in
front), with main's draft-paste bytes and an Enter 50 ms later. Orchestration
worker starts wait on tui-idle as before. A replay-safe launch admits and
claims its ledger row in one write, Qwen Code gets a second Enter, the
desktop and phone share one launch-refusal classifier, and hosts advertise
agent.launch.prompt-carry.v1.

Split out of #23748, which moves the desktop source-control buttons onto
this path.

* fix(agent-launch): keep a short-lined multi-line prompt on a local zsh launch line, as main did

#24257 moved every multi-line or over-512-byte prompt off the typed launch line and pasted it after readiness. The phone's AI buttons and review notes, whose multi-line prompts main typed whole into zsh, then reached Claude 0.5-3 s later and their RPC reply waited for the paste.

The host now names the shell a local macOS or Linux line is typed into, the way the spawn picks it, and a multi-line prompt rides a zsh line when every line is at most 512 bytes and the whole line at most 8 KB. A real-zsh test types such a line through Orca's own ready barrier and startup write, including when a slow user config makes the write land early. Elsewhere the measured unsafe cases keep the paste: bash 3.2 runs multi-line lines piecemeal, fish drops an early multi-line write, and any shell loses a line over 1 KB written early.

* test(agent-launch): keep the real-zsh launch-line test out of the Windows lane's gate scan

The Windows lane registration check read `const ZSH_PATH = process.platform === 'win32'` (the head of a multi-line ternary) as a Windows-true flag, so `describe.skipIf(!ZSH_PATH)` looked like a Windows-only suite. The file is POSIX-only; the zsh lookup is now a function.

* refactor(protocol): move the agent.launch capabilities into their own module

Main's protocol-version.ts sits at the 300-line cap, so the prompt-carry capability pushed it over. The four agent.launch capabilities and their doc move to agent-launch-runtime-capability.ts, re-exported by name and spread into RUNTIME_CAPABILITIES at the same position; the advertised lists and every export are unchanged.

* refactor(protocol): import the agent.launch capabilities from their own module

`export *` from protocol-version left the four names undefined under the mobile recording loader, which resolves a relative import through a Proxy with no own keys, so 37 phone recordings lost agent.launchReplay. Importers now name agent-launch-runtime-capability directly; protocol-version only spreads its list.

* refactor(agent-launch): drop the unshipped viewMode field and trusted local caller id

Both were inert in step 1 and existed only for step 2. agent.launch will become a
public plugin API, so every wire field is permanent once shipped; a top-level
viewMode reads as "choose terminal vs chat", which the host decides. Step 2
introduces placement and view intent under a placement object instead.

* fix(agent-launch): read Codex's provisional startup from the rule files' hold anchor

Main (#24375) moved Codex's provisional-header check into codex.json's
provisional_startup hold anchor and deleted codex-terminal-readiness.ts, so the
launch readiness hold now asks showsHoldAnchor, as main's own settled check does.

* fix(agent-launch): hold rule-file name titles to quiet for a launch, and census the zsh fixture

Main (#24375) answers a name-only title from each agent's rule file ahead of the
sustained-title lane, so gemini.json's name_title settled a launch readiness wait
on the shell's auto-title while Gemini was still booting. A launch now asks quiet
of every weak idle verdict, as that lane did.

Main's readiness census requires a recorder for every runtime fixture; the zsh
prompt recording is a non-agent control. Gemini's synthetic baseline is
regenerated for this PR's stated change: a bare gemini title is no longer its
rest mark, so name-only rows settle weak, and a fresh working or blocked status
is no longer overridden.

* fix(agent-launch): paste a launch prompt only when the launched agent is proven in front

A launch pasted its prompt unless a shell was proven in the terminal's
foreground, so any read that could not prove one let the prompt through. After
an agent exited at startup, its shell turned bracketed paste on at the next
prompt, readiness fired on it, and the prompt was typed into the shell:

- macOS: a pane runs its shell under login, so the process-group fence's root
  was never the shell's group and never proved it; the cached foreground name
  could also still name the exited process.
- Windows Git Bash and WSL: the shell-alone-in-its-job check never answers.

Now one fresh read of the terminal's foreground decides: agent, shell or
unknown. Only 'agent' lets a write through (paste, Enter, second Enter, reused
panes too); 'shell' still drops a ready signal. A Windows host never proves the
agent, so there the launch line carries the prompt at any size, as on main.

* test(agent-launch): cover the Windows QA stub, a grok override that exits at once

* fix(agent-launch): keep the local socket alive while a prompted launch waits for its agent

A launch with a prompt now waits up to 60 s for the terminal agent to be
ready before it writes the prompt, and reports not-delivered when the agent
never is. The local runtime socket closes a connection idle for 30 s unless
the request is a long poll, so a launch whose agent exited at startup lost its
reply and the caller saw 'runtime closed the connection' instead of
not-delivered. Classify a prompted agent.launch and agent.launchReplay as a
long poll, as orchestration.workerStart already is for the same wait.

* refactor(agent-launch): narrow the launch params by 'in' instead of a cast

* fix(agent-launch): find a launched agent behind a wrapper that leads its process group

A tcsh or nu launch line runs the agent from /bin/sh '<script>', and a
wrapper script that does not exec its agent does the same: the wrapper leads
the terminal's foreground process group and the agent is a member of it. The
fresh foreground read names the group's leader, sh, so a prompted launch was
refused or pasted late (M4Air tcsh: 2 of 4 not delivered, 2 pasted ~9 s late).

Before that read, take the host's process-group observation as positive proof
when it names the launched agent among the foreground group's members and is
younger than a ready signal's quiet window. It never proves a shell.

* fix(agent-launch): judge the foreground-group proof by when its capture began, not how long ps took

The age the host stamps on a process-group observation runs from the start
of its whole-machine ps, so on a loaded Mac a capture begun after the read
was asked for still read as older than 1 s and the proof was dropped. Count
an observation whose capture began after the read was asked for, less the
window a shared capture is reused across.

* test(agent-launch): keep the crash-guard live test out of the Windows lane's gate scan

The Windows-lane registration scan read the const assigned from a platform
check as a Windows-only gate, though the suite runs everywhere but Windows;
find zsh in a function instead, as the real-zsh typed-line test does.

Under load the fresh foreground scan can fail to answer, which lets the
shell's prompt settle readiness (2 of 4 paired runs). The guard still refuses
that write, so assert the refused write, the property that must always hold.

* perf(agent-launch): read a local pane's foreground from its own terminal, not the whole process table

The foreground read that gates every launch paste ran the daemon's
inspectProcess capture and then a fresh scan, each a whole-machine ps; the
fresh one also waits for any capture already running before it starts its own.
Measured here at load 5: 1.2 s a read (M4Air QA: 3.4-5.0 s, and worker starts
17.6-32 s against main's 9-12 s at load 25-84).

On a local macOS or Linux host, take the pane's root pid from the provider's
session inventory and run one ps limited to that pane's terminal. Its
foreground process group decides: the launched agent or any non-shell member
is the agent (a wrapper that did not exec its agent leads the group), a group
of shells alone is the shell. Same pane, same verdict: 2.7 ms a read. SSH hosts
keep the relay's observation and name.

* test(mobile): re-measure the web app's script sweep after agent.launch's capabilities moved out of protocol-version

The mobile web bundle check failed at 124 assets against a ceiling of 123. Main already sat
exactly on that ceiling: its sweep table read 69 scripts at 16 routes while the tree builds 73,
the whole margin of 4. This branch imports the agent.launch capabilities from their own module,
so protocol-version is no longer pulled into the root layout and four other routes. That moves
which routes share which modules, and the Qoder capability module, imported by protocol-version
and the AI-vault resume path, no longer shares an importer set with anything, so it gets a chunk
of its own: 74 scripts.

The fence says to re-derive the bound rather than raise it, so the sweep is re-measured on this
head (every prefix of the sorted route list). The worst route now adds 10 scripts (session), not
9, which moves the pinned shell crossing from 32 to 30 routes; main re-measured on its own lands
on the same crossing.

* fix(agent-launch): a worker's brief needs its agent found in front, and Grok's start answers on its composer

A paired-server worker start whose agent exited at startup typed its brief into the server's
shell, which ran it: the idle wait can settle on a shell back at its prompt, and the brief was
written with no foreground read. Both worker-start paths now check before each brief write, as a
launch prompt is checked: on a host that can find the agent in front it must be there; on one that
cannot (Windows) a shell proven in front still refuses, and anything else writes as before.

A Grok worker start waited ~10 s more than main: its only rest signal is its bare name, which a
launch holds to quiet output, and Grok animates its logo for ten seconds after its composer glyph.
A worker start for an agent whose rest signal is its bare name and whose composer draws a marker
(Grok, DSH, mimo-code) now also answers on that marker, whichever comes first.

* fix(mobile-chat): a failed message's text is added to the draft, and an expired resend no longer blocks that text (#25149)

* fix(mobile-chat): a returned message is appended to the draft, and an expired resend id is spent

* test(mobile-chat): leave the idempotent append to the shared rule's own test

* docs(native-chat): say a whitespace-only draft counts as empty

* docs(mobile-chat): don't overclaim where returned text survives

* feat(native-chat): answer /context in chat view for OpenClaude and OMP (#22294)

* feat(native-chat): answer /context in chat view for Claude

Over a terminal-backed chat, Claude's /context paints a grid only the hidden
terminal sees and records nothing in the transcript, so the chat showed
nothing. The chat host now answers it itself: the transcript decoder keeps
each assistant response's API usage and model, and the composer replies with
the same estimate the CLI statusline shows (input + cache tokens against the
model's window) instead of typing the command into the PTY. The command is
also listed in the curated Claude catalog so the slash menu offers it.

* fix(native-chat): only state a /context window the host can establish

The /context answer sized the window from the transcript's model id, which
never carries the [1m] suffix, so a 1M session read as 200k (e.g. 450k / 200k,
225%). The window now comes from the session's tracked model resolved through
the host CLI's own model listing (the resolvedModel field the list_models probe
already returned), and only a [1m] id that matches the model the transcript
last answered with is sized; anything else reports the used figure alone.

Also:
- Offer /context only in the desktop terminal-backed composer; the shared
  catalog is mobile's too, and mobile cannot answer it.
- Answer a typed /context even with images attached, as the picker does, and
  keep the attachments armed instead of sending them to the terminal.
- Report nothing until a response lands after a /compact or /clear sent from
  the chat, instead of the pre-compaction size.

* test(native-chat): pin resolvedModel through Claude model discovery

* fix(native-chat): say /context is unavailable when the host never reports usage

A host that predates usage decoding, or a scraped view, decodes Claude's
replies without a model or usage, so the chat promised an answer after the
next response that would never come. Once the agent has answered and no
answer names its model, say usage is not available for this session.

* feat(native-chat): answer /context for OMP instead of Claude

Claude and Codex answer /context themselves in the structured chat lane, so
the terminal-backed Claude answer, its [1m] window rule, and the resolved-model
plumbing through the model listing go away.

OMP's /context only paints a panel inside its TUI. The OMP decoder now keeps
the provider, model and usage of each reply (none for aborted or errored
replies, which OMP's own gauge skips) and turns compaction rows into the
existing compaction boundary. The OMP model listing keeps each model's
context window, and the chat answers /context from the last reply's prompt
size against the window of the provider/model that served it.

* feat(native-chat): show OpenClaude's own /context report in chat

OpenClaude writes its /context grid to the transcript as a
<local-command-stdout> row, which the chat hid as harness noise. The live
message preparation now turns the stdout row that answers an opted-in command
(/context for OpenClaude) into command output with the ANSI colors stripped,
and the notice row renders command output in monospace so the grid keeps its
columns. Replies to other local commands stay hidden, and Claude is not opted
in. OpenClaude's slash menu now lists /context; Claude's does not.

* test(native-chat): pin OpenClaude /context output through live message preparation

* test(native-chat): pin the OMP context window through model discovery

* test(native-chat): pin monospace rendering of command output

* test(native-chat): restore the notice row suite the command-output test replaced

The previous commit rewrote NativeChatNoticeRow.test.tsx wholesale, deleting
main's compaction, tone, plan, provider-notice and old-reader coverage. Restore
it and pin monospace command output through the message row instead.

* fix(mobile): keep OpenClaude /context off mobile, which cannot show its report

The shared slash catalog now lists /context for OpenClaude because the desktop
chat surfaces its transcript reply. Mobile's transcript fold does not, so the
command did nothing there. Mobile now offers the catalog minus commands answered
only by a surfaced reply, which returns its OpenClaude menu and send
classification to main's behavior.

* refactor(native-chat): drop the unread estimated flag from context usage

Left from the earlier design; the answer text states the estimate itself.

* fix(native-chat): keep /model replies hidden after an OpenClaude /context

Skill surfacing ran first and rewrote non-catalog envelopes such as /model into
plain user text, so command-output pairing no longer saw them. A later /model
reply then paired with the earlier /context envelope and appeared in the chat.
Pair outputs against the raw envelopes before skill surfacing.

* fix(native-chat): word the OMP /context answer for a compacted session and show it as an aside

After a compaction the agent has already answered, so the unknown-usage
line now promises the next response instead. The host answer is one
sentence, so it draws as the muted line it replaces rather than a
monospace grid. The provider/model selector now comes from one helper
shared by the OMP listing parser and the answer, and new tests drive
real OpenClaude and OMP transcript lines through the decoders.

* refactor(native-chat): pair command replies by row link and declare /context replies on the catalog

A `<local-command-stdout>` row now answers the command row its `parentUuid`
names, carried on decoded messages as the optional `parentId`, instead of the
newest command row at or before its timestamp. A reply with no loaded linked
row (older host, command outside the tail window) stays hidden.

How each agent's `/context` is answered is declared once, as `reply` on its
catalog row (`composer` for OMP, `transcript` for OpenClaude). The slash menu,
the composer's answer, the transcript surfacing and the mobile catalog all
derive from it, and both send paths share one intercept. Mobile no longer lists
OMP `/context`, which did nothing there.

* perf(native-chat): skip command-output surfacing for agents that declare no transcript reply

Every Claude-format row now carries its parent link, so once a session holds any
local-command reply (/model, /compact) the surfacing pass built a map of every
message on each live update and changed nothing for agents like Claude. Agents
whose catalog declares no transcript reply now return before the scan.

* fix(native-chat): the agent's exit ends its record, and an unconfirmed stop is joined instead of held (#24862)

* fix(native-chat): a child's root exit is reported even during its close, and bookkeeping after it never reads as unproven

- Both connections report the root process's exit once, with `expected` set when a close had
  begun. A close that came back unproven and whose root exits later is finished by the adapter,
  and its end reaches the host like any other.
- A Claude close whose resume-point write fails after the exit was proven, and a Codex close whose
  terminal row is refused, now end the session and report the failure, instead of keeping a dead
  child indexed as if its exit were unproven.
- A Codex close whose forced tree kill can't prove the descendants gone but saw the root exit
  reports the descendants and counts the root exit.
- Every child exit with an identity, expected or not, is forwarded to the host.

* fix(native-chat): the exit ends the child's record; an unfinished stop is the child's own close, which everyone joins

- The host keeps no stored "stop still owed" record any more. A stop begins the child's close
  (`child.close`), which lives on the child and ends with it. A second Stop, the idle reaper,
  quit, a send and an option/answer/goal/rewind all join that close instead of retrying a
  separate obligation.
- A caller waits on the close only as long as the step deadline; the close itself is never
  abandoned. A proof that lands after every caller stopped waiting reaches the host as the
  adapter's report of that exit, which ends the record through the same handler.
- Once the exit is proven, draining, settling, the lease release and the adapter's
  acknowledgement are each attempted and reported on failure; none keeps the child on record.
  A start, and the handle's close, write a release that failed from this host's proof of that
  exit, so a failed write never refuses a send.
- A start that meets a close still unverifiable is refused with `previousExitUnverifiable`, so the
  queued message is rejected with a send-again reason; nothing is held and nothing starts beside
  the old process.
- The idle sweep goes back to idle reaping only.
- Removes #24333's retry entry points, the wait row and its hold rule, the ask/failure cursors on
  the stored record, and the stop's own wake.

Tests replace the #24333 unproven-stop test: a send joining an unproven close and an in-flight
one, a late proof past the caller's bound, a root exiting after its close gave up, a proven exit
whose resume-point write and lease release both failed, an unverifiable close rejecting the send
and refusing an option change, a surviving descendant, quit and the idle reaper; and Codex's
unverifiable, late-exit and joined-close cases.

* fix(native-chat): a message refused because the old process's exit is unverifiable says so, and to send again

The start failure for a refusal with reason `previousExitUnverifiable` reads "Orca couldn't
confirm Claude's previous process ended. Send your message to try again." instead of "Claude
couldn't restart." The status-row kind and the refusal reason stay in the shared lists for rows
and hosts that still carry them; the catalogs keep one sentence for both.

* fix(native-chat): a close's verdict is the root's exit alone, and what follows it is logged

- A Claude close resolves as soon as the root's exit is proven: the session ends and its `ended`
  report goes out then. Saving the resume point runs afterwards and a failure is logged, so a slow
  or hung write never reads as an unproven exit or keeps a dead child on record.
- A root that exits after its close came back unproven finishes that close through the same path
  as any close, so the session's child work is published as ended (background tasks and subagents
  no longer stay shown running for a dead agent), and a failure there is logged.
- Codex logs a refused final row, and reports a root exit whose forced tree kill could not prove
  the rest of the tree gone the way Claude does, so the host logs it and blocks nothing.
- Both adapters take the host's logger for this bookkeeping.

* fix(native-chat): one handler ends every child's exit, and a join waits on the adapter's own close

- One exit handler (`structured-agent-session-child-exit`) ends a child's record for an exit
  expected or not. `expected` only changes what the chat is told: the stop's cause, its end at the
  stop's ask, the settlement id, and no crash outcome row. The lease release keeps the exit's
  evidence; the handoff guard, lifecycle barrier, sink release and adapter acknowledgement apply to
  both. A Claude journal-sink failure ends in the same step as its stop, as Orca's own fault.
- Joining a close is asking the adapter, whose close is memoized while it runs and bounded by its
  own kill escalation; the host keeps no attempt of its own and no 10 s caller bound. An ask after
  a close came back unproven runs the stop again.
- A close's end is stamped where its stop was asked for (a repeated ask moves it), so the closed
  chat and failed start checks order a message accepted meanwhile after it.
- A start refused because the old exit is unverifiable rejects what was queued in the same step.
- The end of a close the host asked for no longer waits on the cross-session recovery chain.
- The kill no longer waits for the stop event's write; the journal writes rows in order.

* fix(native-chat): an exit's lease release lands whatever the length of its reason

A crash's reason can carry kilobytes of the provider's stderr, and a lease whose death detail is
over 512 characters fails the store's own check. The exit handler cut it, but the release a start
or the chat handle's close re-derives did not, so after a crash whose own release failed every
message was refused as not resumable until restart. The record's builder now cuts the detail to
the record's bound, so no writer can hand it one too long.

* fix(claude): a proven close waits at most 2 s for the output it already wrote

Once the root's exit is proven, the close still waited for the SDK's output reader to end. Something
outside the process tree that holds the output open would keep that close, and every send, Stop
and quit joining it, waiting with no bound. The wait is now bounded; past it the close resolves as
proven and the open output is logged.

* fix(codex): an exit reported inside Orca's close keeps the reason Orca closed it for

The connection reports the app-server's exit inside the close that ends it, so that report ended
every Codex close and replaced the close's own reason (for example, a provider frame that could not
be recorded) with the connection's stderr text in the ended record and the lease's exit evidence.
The session now records Orca's close with its reason, and the exit it ends keeps that reason. The
test connection reports its exit inside close the way the real one does.

* fix(native-chat): quit stops delivery before it drains exit recovery

Every exit now wakes delivery, and teardown drained exit recovery before it stopped delivery, so an
exit settled in that window could start a fresh agent that teardown then killed. Teardown stops
delivery first; queued messages wait for the next launch.

* docs(native-chat): the unverifiable-exit refusal no longer names a caller's wait

The caller's bounded wait was removed; the comment describes the close as it is now.

* fix(native-chat): a stop whose kill did not take is logged, and the next ask kills again

When a close's kill leaves the agent's root running, the host now logs it. Tests pin what a later
ask does: each connection runs its whole stop again (Codex sends SIGKILL a second time), refuses
input meanwhile, and proves the exit once the kill takes.

* fix(native-chat): a start refused over the old process says Orca couldn't stop it

The host reaches an unverifiable verdict only after its own kill left the agent's root running, on
the machine that runs the agent, so the sentence now says that: "Orca couldn't stop {agent}'s
previous process." The refusal reason, failure kind and wire shapes are unchanged. The host test
also checks the failed kill is logged.

* docs(native-chat): an unverifiable close verdict is a root that survived the kill

The host's close runs where the agent runs, so lost contact never yields this verdict; the comment no longer says it does.

* fix(native-chat): a kill that did not take is reported once, by whoever met it

The log added at the close fired beside a Stop's own failure report for the same event. A stop
still reports it through its failure; a send or option change refused over it now logs it at the
refusal, the only place it is otherwise invisible.

* test(native-chat): a second Stop joins a close the first could not prove and retries its kill

* fix(native-chat): say a start refused beside an unstopped process plainly

The rejection now reads "Couldn't stop {{agent}} from before. Send your message again to try once more."
This kind has its own send-again step; every other failure keeps "Send your message to try again."

* feat(activity): filters, matching header, row right-click menu, and stay in the activity view (#25376)

* fix(sidebar): stop workspace reveals from leaving the activity view

Reveals are skipped while the activity view is showing, and activation no
longer lifts workspace-list filters there. Only explicit requests (Go to
workspace, reveal-current-workspace, Cmd+J project row, agent send target,
Cmd+1-9) switch to the workspace list via showSidebarWorkspaceList.

* test(sidebar): keep test harnesses out of the sidebarBody writer census

* feat(activity): workspace-origin filters and a matching options trigger

Activity view gains its own persisted Hide automation-created, Hide CLI-created
and Hide other-client agents toggles, applied through the existing activity
scope filter so the selected-row exemption and identity-preserving return keep
working. The options trigger now uses the workspace view's SlidersHorizontal
icon and shared numeric badge, counting every active activity filter, and Add
project stays visible so no header button shifts between views.

* feat(activity): right-click menu on activity rows

Open, Mark as read/unread, Go to workspace (real workspaces only), Copy (agent
title, plus branch and path for real workspaces), and Clear from list for
finished threads, reusing the row's existing actions and clearActivityThread.

* fix(sidebar): leave the activity view only once activation commits

Go to workspace and Cmd+1-9 switched the sidebar before activating, so a
blocked folder activation still left the activity view. Activation now owns
the switch via showWorkspaceList, applied after its failure gates. The
separate showSidebarWorkspaceList action and the one-line sidebar-body-reveal
module go away: setSidebarBody is the single writer, and the census pins its
callers.

* Add confirmed deletion of nested worktrees (#25668)

* fix(relay): read reconcile's counter units after the cell lock (#25638)

reconcileReservationAccounting computed each cell's absolute reserved_requests
from leases read before lockCellRows, so a host placed in that gap lost its
unit: the counter went to 0 with one lease on the cell.

* Retire automatic profile JSON snapshots with safe recovery and downgrade (#23262)

* test(terminal): restore the live fish fixture prerequisites (#24947)

A restored pane waits for the initial status replay before subscribing to
PTY output. This fixture never settled that replay, so fish printed its
mode-2031 arm before the renderer connected. Its PTY API also omitted the
reset-input listener required by the serializer, aborting attachment.

Settle and dispose the existing startup-snapshot registration and provide
the same reset-listener mock used by the other PTY tests. The real fish
child-stdin assertions and timeouts remain unchanged. No production change.

* fix(shortcuts): defer TUI editing chords in terminal-first mode (#24640)

Restack the original focused change onto current main, preserving every owned source and test blob and the merged CI contract and journal cleanup fixes.

* Skip store notifications when refreshed work items are unchanged (#24530)

* Reuse documentation search excerpts during result navigation (#24574)

Memoize the existing pure excerpt renderer by complete raw text for the current result array, retaining original rendering as a miss fallback.

* Reuse prepared reads while searching saved agent conversations (#24535)

Use schema-complete session columns to enable the existing bounded statement cache without caching result rows.

* Reuse discovered mobile chunks during static traversal (#24774)

A restored pane waits for the initial status replay before subscribing to

* test(jcode): measure the gate against the synchronous path, not the clock

The absolute 1s bound was the flake CI shard 3/8 hit: it is tight enough to catch
a synchronous gate on an idle laptop and too tight on a loaded runner. Measuring
the same POST both ways on the same machine makes the claim a ratio, which is what
the test is actually about. Mutation-checked: a synchronous gate reads 6120ms
against a 1517ms observer.

* test(jcode): drop the wall-clock gate assertion

The bound was machine-speed sensitive and flaked on CI shard 3/8 at 1525ms. The

* fix(jcode): address CodeRabbit review on #22539

- Windows posted no payload at all: the shared builder reads `payload@-` from
  stdin, which the gate has already drained and observer hooks never receive, so
  every Windows event was dropped. Write the env var to a temp file and pipe it.
- The daemon pre-warm never fired for daemon-host spawns, which is the default
  local path; it now runs there too, and from the final env so the daemon gets the
  hook port and token.
- A failed runtime-dir mkdir took down every local terminal, jcode or not.
- removeJcodeManagedHooks matched the raw line, so a user hook whose comment
  mentioned the managed script was deleted; matching on Windows never worked.
- A managed entry left by a copied home or a platform switch is now repointed
  instead of being reported as user-owned forever.
- The OSC colour skip only checked launchAgent, so a command- or telemetry-named
  jcode pane still leaked the reply into its composer.
- `['hooks']` and a commented scalar are recognised, instead of appending a
  second [hooks] table that makes jcode reject the whole config.
- A failed tool's error is marked as tool output rather than agent prose.
- The vault keeps a session's stored name, counts its tokens, and skips
  background_task and [Scheduled task] turns.

* fix(jcode): read the journal once per turn, key prompts by byte offset

The jcode prompt reader ran a synchronous bounded file scan plus a JSON
parse on every hook event. jcode blocks on pre_tool, so a turn that ran
four tools charged the user eight scans of latency it did not need — the
prompt cannot change inside a turn.

- Cache the journal read per pane, refreshed on the turn boundary that
  can change it. The cache holds the whole evidence record, since
  hasExplicitUserPrompt needs the transcript-evidence flag and not just
  the text, and it joins the existing pane-scoped lifecycle (close,
  rename, reset) rather than living in a module singleton.
- Key a journal prompt by its absolute byte offset instead of its
  region-local line index. The backward scan windows the file from EOF,
  so appending shifted every boundary and reminted the key for a prompt
  that never moved; a repeated turn_end then slipped past the same-hash
  dedupe as a second done event with duplicate telemetry.
- Pin the platform in the daemon pre-warm tests. The pre-warm is a no-op
  off POSIX, so the dedupe and retry cases would have passed vacuously
  on a Windows runner.

* fix(jcode): quote the managed hook path, drop tools from patch prompts

Three fixes, all on paths this PR could not exercise locally.

The managed hook command was stored as a bare path. jcode tokenizes that
string shell-style before exec'ing it directly (parse_hook_command,
crates/jcode-terminal-launch/src/lib.rs): unquoted whitespace splits, and
every unquoted backslash is consumed as an escape. So on Windows
`C:\Users\me\.orca\agent-hooks\jcode-hook.cmd` reached exec as
`C:Usersme.orcaagent-hooksjcode-hook.cmd` and no hook fired at all, and a
POSIX home with a space split into two arguments. Store the path
single-quoted (verbatim, backslashes included), falling back to double
quotes for a path containing a single quote. Existing bare entries are
already repointed by the stale-key path, and getStatus accepts both forms
so the repair is not reported as a user-owned hook. The quoting helper was
previously dead code that only tests called; the three production sites
now use it. isJcodeManagedCommand also normalizes separators, since a
`/`-only needle never matched a Windows entry.

Commit-message generation feeds a staged patch to `jcode run` as the
prompt — attacker-influenced text — while jcode's default profile exposes
shell, read, write, and MCP. Pass `--tool-profile none`, which resolves to
an empty allowed-tool set in jcode's config (base_allowed_tools), matching
the read-only posture claude (plan) and codex (read-only) already take.

docs/reference/jcode-hook-events.md was never actually in this PR: the
repo ignores docs/** and tracks reference docs by allow-list only, so the
captured-payload evidence four source comments point at was silently
dropped. Allow-list it.

* test(jcode): pin the tool-profile flag in the generation plan too

The argv assertion lives in two places; --tool-profile none only landed in
one, so the plan test still expected the unrestricted argv.

Co-authored-by: czzczz <chanzrz_zbf@foxmail.com>

* fix(text-generation): refuse an oversized argv prompt on Linux too

The pre-spawn size guard only ran on Windows. Linux caps a single argv
entry at MAX_ARG_STRLEN (32 pages, 128 KiB on a 4-KiB-page host) and
execve fails with E2BIG past it, so an agent that delivers the whole
prompt as one argument — jcode, and the other argv-delivery agents —
failed on a large staged diff with an error the user could not act on.

The cap is per-argument and in bytes, which is why it is not the Windows
line budget: 40k chars trips Windows and is nowhere near the Linux limit,
so folding them together would have refused prompts Linux runs fine.

* fix(jcode): register in main's remote-installer guard, drop our duplicate

Rebasing onto 853 commits of main surfaced two things the earlier branch
had hidden.

main already owns a guard for the issue-#7253 bug class
(`remote-hook-service-registry-coverage.test.ts`). This branch had added a
second, near-identical one — a parallel implementation of a test that
already existed, which is what AGENTS.md's reuse rule is about. Deleted
ours and registered jcode in main's, which is the one that has kept pace
with every agent added since.

Also fixes a missing separator in the mobile icon map. `pnpm tc` does not
cover `mobile/`, so only the session-route closure suite caught it.

Co-authored-by: czzczz <chanzrz_zbf@foxmail.com>

* fix(jcode): decompose the four files jcode pushed over max-lines

Adding an agent tipped four modules past their line budget. AGENTS.md
forbids a `max-lines` disable or a per-file bump, so each is split on a
real seam rather than silenced:

- agent-catalog.tsx keeps `AgentIcon`, which 70+ files import, and the
  rows move out. The rows alone exceed the 300-line budget a `.ts` file
  gets, so they follow the primary/secondary split this repo already uses
  for commit-message agent specs.
- getAgentResumeArgv -> agent-resume-argv.ts, re-exported so the 18 call
  sites keep one import path.
- isDiscoverableSessionFile/pathSegments -> session-file-discovery.ts.
- remoteCodexSources -> remote-session-scanner-codex-sources.ts; Codex is
  the one remote agent with two CODEX_HOME roots.

Also:
- Records the readiness-census baseline jcode now needs. main added that
  gate while this branch was out; the fixture is the recorded 74-case
  matrix, not a hand-written one.
- Restores two entries a rebase resolution silently dropped from
  config/tsconfig.cli.json (gitlab/project-ref-parser,
  startup/shell-path-probe). Nothing to do with jcode; losing them was a
  conflict-resolution mistake on this branch.

* feat(native-chat): open structured chats on the paired Orca server that owns the workspace (#24205)

* fix(native-chat): a host admits structured sessions by client capability, not its own chat setting

A host's experimentalStructuredNativeChat decided whether any paired client could reach
agentSession.* at all, and whether session.tabs.* showed it structured tabs. That setting is the
host user's own launch preference: whether a new agent opens as a chat or a terminal is decided by
whoever launches it. Using it as admission control meant a client whose own preference was
"structured chat" was refused on a host whose preference was "terminal", and chats opened while
the setting was on were withheld from mobile once it was turned off.

The gate now asks one thing: did the client advertise agent-session.structured.v1 (in-process
callers negotiate nothing and are always admitted). Tab projection and restore follow the same
rule. With the setting no longer gating anything, the separate cleanup gate (close, cancel,
unsubscribe, release), which existed only so those kept working after the setting was switched
off, is identical to the main gate and is folded into it. The settings listener that republished
tabs when the setting changed is removed, since projection no longer depends on it.

The host setting still picks the default for launches that start on the host itself
(agent.launch from mobile, orchestration worker-start).

* fix(native-chat): the desktop declares structured chat support to paired hosts

The desktop renderer advertised agent-session.structured.v1 (and the Claude, turn-item and
background-task capabilities that go with it) to its own main process but not to a paired Orca
server. The server therefore refused every agentSession.* call from the desktop and stripped
structured chat tabs out of the tab list it published to it, so a structured chat running on a
paired server never appeared on the desktop, even though the renderer already mirrors a host's
agent-session tabs and drives each one against the server that owns its workspace.

The same renderer reads structured chats on either host, so the remote Electron list now carries
the same structured-session capabilities as the local one, and the capability test pins that
nothing is advertised only locally.

* feat(native-chat): open structured chats on the paired server that owns the workspace

With the structured-chat default on, an agent launched in a workspace that lives on a paired Orca
server always opened as a terminal (or the terminal-backed chat view). Three things kept it off
the structured path: the launch check refused every host but this machine, a remote workspace was
handed to the host-published terminal path before the structured route was even considered, and
the structured launch pipeline sent create and every follow-up call to this machine's runtime.

A workspace's owning runtime is fixed, so the pipeline now derives it from the workspace instead
of assuming this machine (structured-agent-session-owner.ts, the same derivation the chat pane
already uses to read a session). The launch intent carries that target; the pre-create support
check, create, the publication check and fence read, the launch prompt send, held option picks,
the "focus this chat" marker, the placeholder tab's host, and tab close/purge all use it.

The launch check now accepts a paired server and asks that server's own capabilities (read from
the status the client already cached for it) rather than this machine's. An SSH workspace stays
terminal-backed: no Orca runtime runs there. The host still answers createSupport before
anything is created, so an older server that refuses shows the failure in the chat tab.

A chat the user closed before its create landed is now also retired on the paired server when it
publishes, as the local sync already does. Orchestration workers placed on another runtime are
unchanged: federation creates terminal agents only.

* fix(native-chat): negotiate client-chosen launch mode so released phones and old servers keep terminals

Hosts advertise agent-session.structured.client-launch-mode.v1: they admit
structured sessions by client capability alone. A remote client that does
not advertise it (phones released before agent.launch) asks createSupport
to pick the launch mode, so the host keeps answering that with its own
setting, exactly as before. Cleanup methods keep their own named gate so a
future admission condition cannot make close or cancel refusable.

* refactor(runtime): keep the Electron client capability list in its own module

protocol-version.ts is at its line budget; the list is what the desktop
advertises to paired hosts, not the host's own contract.

* fix(native-chat): the desktop declares it picks each launch mode itself

Paired hosts and the desktop's own main process then answer createSupport
by the workspace rather than by their own chat setting.

* fix(native-chat): pin each structured chat to the host it was launched on

- Route: a paired server opens a chat only when it advertises the
  client-chosen launch mode; an older server keeps its terminal. Its
  capabilities come from the store's host status, not the compatibility
  cache that is empty after boot or reconnect.
- A launch command override is this machine's: the route applies it only
  locally, and a host's createSupport refuses on its own override.
- The owning host is resolved once, from the same value the route used,
  and carried on the launch intent, its persisted record (legacy records
  load as local), the provisional tab and every mirrored chat tab. Close,
  purge, retry and reload read it instead of re-deriving it from a
  worktree id two hosts can share; an owner that cannot be named refuses.
- Cancellation tombstones record their host: only that host's
  authoritative inventory retires one, restored cleanup closes it there,
  and a paired host's tombstone expires after 30 days if it never answers.
- A paired server's frame settles launches it published, as the local
  inventory already does for this machine.

* fix(native-chat): a paired server that declines a chat opens its terminal instead

createSupport only reads, so both of its non-answers are settled before
anything is created:
- A paired server that answers it cannot run the chat (a WSL repo, a
  Claude account mismatch, its own launch command override) closes the
  chat tab and opens the terminal the route would have chosen, with a
  notice saying why. This machine's own decline stays a failed chat.
- A host that could not be asked closes the chat tab and leaves one
  failure toast, instead of a lingering "could not confirm" chat.

* test(native-chat): a provisional chat carries its launch's host and hands pre-create failures on

* chore(native-chat): justify the two type assertions this change's lines touch

* test(native-chat): state why each staged test fixture is cast

* fix(native-chat): chats that already exist keep showing whatever the chat setting says

The structured chat setting decides only what new agents open as. With it
off, this machine's structured chats used to be hidden while the host,
which no longer reads the setting, still reported them to the workspace
activation gate, so a workspace holding only a chat opened empty. The
local chat mirror and its startup restore now run whatever the setting
says, the continue-after-restart offer follows the chats that exist, and
the setting's copy says it applies to new agents.

* fix(native-chat): the browser client keeps its host terminal on paired servers

A browser client whose own preferences turn structured chat on took the
structured route for every paired-server workspace, but its handshake
never says it reads structured sessions, so the server refused the chat
and the user got a failed chat tab where a host terminal used to open.
The route for a paired host now also asks what this client advertises to
it: the desktop's list does, the browser client's does not. Its handshake
list is now a named constant the route reads, so the two cannot drift.

The chat setting's copy now says it runs on paired Orca servers too;
WSL and SSH hosts still use terminal chat.

* fix(native-chat): a retried launch a paired server declines opens its terminal too

A launch restored after a reload settles only through its Retry, so a
declining paired server left a failed chat there while a first launch got
the server's terminal and a notice. The chat's Retry now hands the same
pre-create failures to the same replacement, carrying the prompt the
launch had staged.

* refactor(native-chat): a paired host's cancelled-chat record ends on its 30-day TTL

The paired census re-read a host's whole inventory after every
authoritative frame to retire tombstones, and a tombstone restored after
a reload needed a second such frame, so in practice it retired nothing.
A tombstone guards a random session id and is inert once stale; the chat
is already closed on its host whenever a frame shows it. The census, its
trigger in the mirror layer and its cleanup are removed; the owner-scoped
tombstones, close-on-sight, the TTL and publication marking from frames
stay.

* fix(native-chat): a chat's pane and status read from the host recorded on its tab

The chat pane and its sidebar status still derived the host from the
workspace id, which two hosts can share; a paired chat in a non-active
same-id workspace was read from this machine. Both now read the owner
stamped on the tab, as close, purge and publication already do.

* fix(native-chat): "Resume in chat" follows the terminal resume's host rule

Agent Session History offered "Resume in chat" for a conversation
recorded on this machine into a paired server's workspace, where its
transcript does not exist. A chat now resumes a conversation only on the
host that recorded it, as the terminal resume does, and that host is the
one asked whether it can resume history.

* fix(native-chat): the chat setting says older paired servers keep terminal chat

* test(native-chat): pin that a host advertises the client-chosen launch mode

* fix(native-chat): mirror this machine's chats only where it holds them

Round 1 ran the local chat mirror for everyone so existing chats show
whatever the setting says. That gave every desktop a permanent
session-tabs listener, which turns on the runtime's phone replication
paths, plus two full session-tab censuses at startup, and made the
browser client mirror its remote host a second time.

The runtime now says whether it holds structured chats: its structured
host is built only when saved chats were restored at startup or a client
created one here, and it announces the moment one is built. The mirror,
the startup restore and the continue-after-restart offer run only when
the setting launches chats or the host holds some, and never in the
browser client. A chat a paired client creates here with the setting off
still appears at once. The chat behaviour settings show wherever chats
exist, and the setting's copy says it picks what new agents open as. The
toggle-off teardown this made dead is removed.

* test(native-chat): route a paired-server launch over the capability lists both sides really advertise

* test(native-chat): record install listeners without a cast

* fix(native-chat): a paired server admits a chat before any of it exists here

The desktop opened a paired server's chat tab, launch record, queued
prompt and focus intent before asking the server, so a "no" needed a
replacement that undid and redid all of it, and every piece it missed
was a bug: the workspace deselected, the caller told "failed" while a
terminal ran its prompt, the caller's arguments and other queued prompts
lost, and a create whose reply was lost treated as never sent.

A paired launch now asks the server first and commits nothing until it
answers. Admitted opens the chat as before. Declined runs the caller's
own launch as the server's terminal, with the existing notice (a resume
fails instead, having no terminal equivalent). Unreachable opens nothing
and names the server in one toast. The new-tab launcher reports the
host's surface for paired workspaces, as it did before paired chats,
with the prompt delivery of whichever surface got the prompt. The
replacement and its error classes are gone, and the probe inside a
launch is back to its old meaning: a "no" is a failed chat with Retry,
and no answer leaves "Could not confirm" with Retry and the prompt kept,
here as on this machine.

* fix(native-chat): mirror this machine's chats only once it holds one, not once its host is built

Session history, resume preparation, terminal resume commands and replay-safe phone launches all
build the structured host for users who never had a chat, which turned on the chat mirror and the
structured-only settings rows until the next restart. The signal is now derived from the host's
records (or a records file still owed its import) and pushed when the first chat is restored or
created. A throwing listener no longer fails the install that fired it.

* fix(native-chat): a fork's reveal never seeds a terminal beside the surface the launcher opens

Forking into a paired-server workspace revealed it as if nothing would open there, so the reveal
created a blank host terminal beside the forked chat (and beside a forked agent terminal on main).
The launcher always opens the fork's surface itself, so the reveal now says so for every surface,
as the fix-checks launch already does.

* fix(native-chat): a declined direct launch keeps the caller's CLI args; an unreachable resume toasts once

When a paired server declines a "Fix checks" chat in a new workspace, the terminal that opens
instead now carries the recipe's saved CLI arguments, launch platform and launch source, as the
terminal route did. "Resume in chat" to a server that cannot be reached showed the admission's
"Could not reach" toast and the vault's generic one; the admission marks its failure notified and
the vault adds nothing.

* fix(native-chat): a declined background create opens its terminal without switching workspaces

Since #23974 a worktree create the user moved away from must not pull them onto the new
workspace. When a paired server declined that create's chat, the fallback terminal opened as a new
agent tab, whose host create selects the workspace. The create now opens its own agent terminal the
way main's background branch does: in place from the request's startup plan (so its CLI args carry),
without selecting the workspace. A create the user is still watching keeps the new-tab fallback.

* test(native-chat): name the launch's host in main's new outbox fence test

Main's new staging-failure test calls settleStructuredAgentLaunchPrompt without the target this PR
made required; it is a local launch, as in the sibling tests.

* fix(native-chat): a paired server's new chat shows no model until the server reports the one it started

A chat on a paired server starts with the server's saved model and options, but the picker showed
this desktop's saved selection (or the catalog default) until the server reported a model, and a
pick made in that window was remembered on the server under that guessed model. A paired launch
now carries no desktop seed, and until the server reports its model the picker names no model and
takes no picks. Local chats are unchanged.

* test(native-chat): seed the paired repo without a cast

The repo literal already satisfies Repo, so the changed-lines cast gate has nothing to excuse.

* feat(native-chat): createSupport reports the saved selection a new chat on this host starts with

A chat on a paired server starts with the server's saved model and options, which the desktop could
not read, so its picker showed a guess. createSupport's answer, which the desktop already waits for
before a paired launch, now also carries that seed as a new optional field (older clients ignore it).
Create and createSupport read it through one resolver so they cannot drift.

* fix(native-chat): a paired server's new chat shows the selection the server will start it with

The paired server now names its saved model and options in the admission answer the desktop
already waits for. That seed goes into the launch intent and its persisted record, so the picker
shows the server's model at once, stays pickable like a local chat, and remembers picks on the
server under that model; a reload shows the same. The locked picker remains only for a server too
old to name a seed.

Also moves host admission and launch-outcome tracking into their own modules: the latest main
merge left structured-agent-session-launch.ts over the max-lines limit.

* test(native-chat): expect the launch intent's new seed argument in exact-call assertions

* refactor(protocol): move the Electron remote client capability list into its own module

Merging main left protocol-version.ts one line over the max-lines limit on this branch. The list of
capabilities the desktop advertises to a paired host moves, unchanged, into
electron-remote-runtime-client-capabilities.ts, the module the next PR in the stack already uses
for it; importers point there.

* fix(native-chat): a paired chat with no saved server model is pickable; Retry shows the server's current seed

A server whose user never saved a chat model sends no seed, and the desktop showed a locked,
model-only picker for it, although that is the common case: no server that can admit a paired chat
predates the seed field. Such a chat now behaves like a local chat with no saved model: the CLI
default, pickable. The lock and its snapshot helper are gone.

Retry kept the first admission's seed while the create probe, which already runs on every attempt,
reported the server's current one and dropped it. The probe's seed now replaces a paired launch's
seed and the picker's, so a retried chat shows what its create will run.

* test(cross-version): stub the launch seed resolver createSupport now reads

* test(protocol): pin the desktop capability divergence against what a paired server receives

Every paired transport sends the shared remote base plus the Electron list, so the
divergence test now compares that union with the renderer's local list instead of
the declared Electron list. A capability added only to the shared base can no
longer slip past it. The two base-only capabilities it surfaced are recorded:
skills.install-result.v2 has no local caller; the authoritative-inventory label is
read by the local tabs sync but dropped by main, and is marked unsettled.

The turn-item and both background-task-stop capabilities were already sent through
the shared base, so the Electron list no longer repeats them. The wire set is
unchanged; this PR's real change on the wire is structured.v1, the Claude
structured capability and the client launch-mode capability.

* fix(native-chat): the desktop tells its own host it picks each launch mode, so retrying an existing chat works with the setting off

* docs(native-chat): name the real exit for the released-phone createSupport rule

* fix(native-chat): the route reads the capabilities a paired host actually receives

The renderer decided whether a paired host would admit a chat from the desktop's Electron list, but
every desktop transport sends that list plus the shared remote base. Th…

* feat(i18n): localize onboarding checklist steps to Japanese

Add Japanese translations for the 16 setup-checklist step names and
descriptions (`auto.components.feature.wall.feature.wall.setup.checklist.
localized.copy.*`) that were still falling back to English in the Setup
Guide modal and settings pane, and extend the checklist copy test so the
Japanese catalog is guarded alongside Korean.

並列 is the term Claude Code's Japanese docs ("並列セッション"), Cursor's
Japanese coverage ("並列エージェント"), and the Zenn/Qiita worktree
articles use for running several worktrees or agents at once; 並行 was
the outlier.

* test(i18n): assert setup checklist catalog values are strings

* fix(i18n): align the Setup Guide subtitle with 並列 in Japanese

The subtitle sits directly above the 並列開発 step in the same modal and
the Korean catalog already renders "parallel agent work" as 병렬; use
並列 in Japanese too so the modal does not mix 並行 and 並列.

* fix(native-chat): keep a Stop's note with the turn it waited for and stopped (#25056)

* fix(native-chat): a Stop binds only the turn it actually stopped

A Stop pressed before any turn showed used to claim, at end-write time,
whatever turn the stopped send later opened, even when the Stop stopped
nothing. A turn that then died on its own read as "Interrupted" (your
cancellation) instead of "Failed".

Now a person's Stop that named no turn binds, in memory only, every turn
that ends while the Stop settles, and afterwards only the turn its
interrupt took. The settle ends a still-running stopped turn once. A
relaunch finds nothing in memory, so an unsettled turnless Stop binds no
turn. A Codex Stop whose answered turn does not open within its wait, or
whose send's answer was lost, now answers refused, so the host ends the
child and the turn can never run.

* fix(native-chat): keep the person's queue pause and close binding after a Stop settles

A host stop or eviction with no turn running now defers to a person's
Stop while its queue pause still holds with nothing sent since, read from
rows, so a held card is not handed off on reopen after a Stop that did
nothing or whose kill failed.

A person's close that named no turn opens a settle around its child's
end, so a turn that end cuts reads as theirs.

A press opens its settle only when the latest Stop event is its own or
the one in force it repeats: a late Stop, a card's interrupt or a lost
event row reopens no earlier Stop.

A Codex Stop that cannot reach a turn still able to open says the Stop is
unconfirmed rather than that no turn ran, and a second Stop still reaches
a turn an earlier wait left unopened.

Also drops the unused openedBy plumbing and the unreachable "a written
cancellation stays one" rule, and pins a relaunch after a named Stop.

* fix(native-chat): a Codex Stop agrees on both presses when a turn is still owed, and pin the close's settle

A Codex Stop that waited for a turn Codex answered a send into now answers
"may still open" whenever that turn neither opened nor ended and its send
is still owed, however the wait ended (it ran out, or the thread went
idle). Before, a first press after an idle thread said no turn was
running and kept Codex, while an identical second press ended it.

Adds a test that a person's close the conversation outlives (as /clear
does) closes its settle, so a later turn that ends on its own reads as a
failure.

* test(native-chat): a Stop whose event row failed binds no turn to an earlier Stop

With one ordered journal writer the Stop's event is in the fold when its
write returns, so the press reads whether it owns the latest Stop from the
fold instead of awaiting the write. Pins the case the read must refuse.

* test(native-chat): name the settle, not a stream drain, in the Stop's own-end test

* test(native-chat): a Codex Stop answered before Codex ends the turn reads interrupted throughout

Codex answers an interrupt it took before it sends turn/completed (interrupted):
on TurnAborted the app-server answers pending interrupts, then ends the turn, on
one channel. The test fake did the reverse. It now answers first and ends the
turn on a later read, and the tests that read the turn's end right after a Stop
wait for it.

New end-to-end test through the shipped host, journal and Codex adapter: with
the real order, every end row of the stopped turn reads interrupted by the Stop
(named, unnamed, and a Stop pressed while turn/start was in flight). Breaking the
settle window turns the in-flight case red: the Stop's own end row then has no
verdict, which reads as failed until Codex's end lands.

* fix(native-chat): a Codex Stop interrupts a turn Codex answered but has not opened at once

A Stop that named no turn, made after Codex answered a send but before the turn
opened, used to wait up to 5 s for the turn to open before interrupting, and
ended the Codex process when it didn't. The stated reason, that Codex refuses an
interrupt until it opens the turn, holds only part of the time: with no turn
active, Codex takes an interrupt once its thread runs (turn_interrupt_inner),
and refuses it with -32600 "no active turn to interrupt" before that or once
the turn has ended.

The Stop now sends the interrupt at once. Only on that refusal, while the turn
has neither opened nor ended, does it wait for the turn to open (bounded at
5 s) and send it once more. A turn that ended meanwhile was nothing to stop. One
that never opens, or that an earlier wait already gave up on, fails the Stop,
and the host ends the child as before. Sends still wait for the turn to open
before steering into it.

The test fake models Codex taking an interrupt once the thread runs (run()).

* fix(native-chat): every Codex Stop waits for an answered turn to start, as the first did

A Stop whose interrupt Codex refused as finding no active turn skipped the wait
when an earlier wait, a Stop's or a send's, had already given up on that turn.
Every press now waits its own bound and retries once if the turn starts, so a
turn that opens during a later press is still stopped. Both presses still reach
the same verdict when it never starts.

* fix(native-chat): a Codex Stop that ends the child before any turn opened withdraws its send

A Stop on a Codex turn that was answered but never opened ends the Codex
process. That end settled the send as in doubt (unknown, recovered), and the
client's outbox holds every later send behind a send in doubt until the person
presses Retry, which re-sends the very message they stopped. The chat looked
stuck.

Codex records a prompt only once its turn has started, so a send whose turn
never opened never ran. When the Stop's refusal says so (turnMayOpen), the child
end now settles the unanswered sends as withdrawn, the verdict Codex's own
interrupted-turn end already gives an unechoed send. The flag rides on the owed
wind-down, so a retry after a failed child end withdraws them too. Claude's
child end still leaves its unanswered send in doubt.

* fix(native-chat): derive the withdrawal of a Codex send whose turn never opened

Replaces the flag the Stop carried to the child's end, and its copy on the owed
wind-down, with a reading of the journal at the settlement that lands. A Codex
child's unanswered send is withdrawn when a person's Stop is in force since it
was sent and no turn row ran, or was written, after it; any other end (a turn
that opened, a host's close, a crash, Claude) still leaves it in doubt. A
retried wind-down reads the same rows, so it withdraws the same sends.

* fix(native-chat): keep a send in doubt when a turn was open for it

The derived withdrawal read a turn as open for a send only if it still ran or
was written after the send. A send steered into a running Codex turn whose
interrupt failed met neither once the adapter's end settled that turn ahead of
the host's settle, so it read withdrawn, though Codex drains a steer into the
running turn and may hold it. A turn that ended after the send was handed over
was open for it too: such a send stays in doubt, as before.

Pins that case, and that a send made after the Stop, to a child that then dies
before its turn opens, stays in doubt.

* fix(native-chat): withdraw a Codex send by whether it started its own turn, not by timing

Whether a turn was open for a send was read from end times: a turn that ended
after the send's handover counted. A send made while a Stop ended the turn is
handed over once that turn reads ended, yet Codex's own end for it can arrive
later, so such a send whose own turn never opened read in doubt again, and the
chat's queue held behind it.

The handover already records where the send went: its message joins the turn
running then (a steer) or belongs to no turn (it starts its own). Only a send
that started its own turn, with none opened since, is withdrawn; one that
joined a running turn, or has no recorded place, stays in doubt.

The Codex test fake takes an answered interrupt as Codex does, dropping the
turn before its end arrives.

* fix(native-chat): leave no Stop row when the Stop took back a send that never ran

A Stop on a Codex send whose turn never opened ends the child, and the child's end
takes the send back into the composer. The Stop still wrote "Cancellation
requested." at the conversation level, so with the send gone it sat under the
previous finished turn and read as if that turn had been stopped. A Stop that found
no turn running and whose child end took back every send it found now writes no
row; a Stop of a running turn, or one that leaves a send in doubt, still does.

* fix(native-chat): keep a Stop's note with the turn it waited for and stopped

A Stop pressed while Codex was still opening the turn read the note's place
before it waited: no turn was running yet, so "Cancellation requested." became
a loose conversation row, never folded with the turn, drawn below whatever came
next. Once the interrupt takes a turn that opened during that wait, the note is
now scoped and keyed to that turn, as a normal Stop's is. A refused or
unconfirmed Stop, and one that writes no row, are unchanged.

* fix(native-chat): key the Stop's note by the turn the interrupt took

* fix(native-chat): count a send whose answer was lost when a Stop takes it back

The no-row rule counted only pending sends, but the child's end also takes back a send this process left in doubt when Codex's turn/start answer was lost. That case still wrote "Cancellation requested." under the previous turn. Both now read one predicate, so they cannot drift apart.

* test(native-chat): pin which sends a Stop's child end can take back

A send an earlier process left in doubt is never withdrawn and never holds the row back, and a queued card's send is never counted.

* test(native-chat): read the outbox reconcile from where main moved it

* fix(native-chat): mark a chat whose start failed on its tab and workspace row (#24904)

* fix(native-chat): mark a chat whose start failed on its tab and workspace row

A chat whose start the host refused said so only inside its own tab. Its
row now carries the failed verdict the host publishes for a refused start,
so the tab and the workspace row show it from elsewhere until a retry
starts it or the tab closes. The + menu no longer shows a failed start as
still starting, so launching the agent again retries it.

* fix(native-chat): date the failed-start mark by the failure; keep the + menu change for a separate PR

The failed-start mark on a chat's tab and workspace row is now dated by when
the start failed, the way a failure the host reports is dated: it ages out on
the same schedule, a restart does not bring an old mark back, and a failure
the user already saw stays read. The failure time is saved with the launch
record so a restart keeps it; records saved without it fall back to the tab's
creation time.

The + menu change (letting a failed agent be picked again) moves to its own
PR: its correct form makes a new chat instead of retrying the failed one,
which changes how launches join.

* test: name the local host on the saved failed-launch record

* fix(native-chat): re-check an unconfirmed chat start when its host is reachable again

A chat create whose reply was lost, or that a reload interrupted, stayed unknown until the
user pressed Retry in its tab. Each host subscription opens with one full inventory; on it,
every launch that host owns whose outcome is unknown (including ones restored from the saved
launch record) is re-checked through the existing Retry path, so it settles to started or
failed. One still unknown waits for the host's next return; cancelled launches are skipped.

* fix: restore main's lint and localization checks after the nested-worktree delete dialog (#25684)

#25668 added DeleteNestedWorktreesDialog and its preserved-branches toast
with translate() keys under worktree.nestedRemoval, but not the matching

main, and on every PR that merges it. Entries generated by the catalog
sync script from the code's own fallbacks.

* fix(sidebar): import worktree removal types once

#25668 imported from shared/worktree/removal twice in

* feat(relay): drain pace window as a reviewed same-cap input, with drain-aware 503 gates (#25639)

* feat(relay): drain pace window as a reviewed same-cap input, with drain-aware 503 gates

The same-cap roll drained every cell over a fixed 300 s window, so a US roll
re-placed hosts at ~2/s and spent ~10 minutes draining and waiting for quiet.
The window is now a dispatch input from a closed set (300000, 60000, 30000),
defaulting to today's 300000.

- Below the default is refused for anything but US general cells; Asia drains
  are bound by their targets' accept rate, and migration-only cells hold no hosts.
- A non-default window must be named in the confirmation, the canary authority
  records it (v2), and a batch may run at its canary's window or slower only.
- Each cell job re-checks the window, scales the restart-safe timeout with it
  (15-min lease + window, unchanged at the default), and records what the cell
  applied and when it settled.
- The report-only shadow gate takes the director's drain-return deferrals out
  of the 503 count (window and baselines), adds the rung's 5-min non-drain 503
  budget and a Retry-After check, and reports the measured re-placement rate.
- relay-workflows.md documents the pace ladder and what each rung records.

* fix(relay): judge paced drains on counted 503s against the pre-drain minutes, and seal the canary's pace verdict

Review of #25639 replayed the shadow gate: it read 10-01 c29 as unverified (the
log read stopped at 20k entries), false-blocked 10-02 c22, and was blind on four
cells whose 24 h/48 h baseline held an incident.

- Director 503s now come from Cloud Run's request_count, aligned per minute by
  Cloud Monitoring, so volume cannot truncate the count.
- The background is the median of the 10 same-day minutes before the drain;
  the 24 h/48 h baselines are gone.
- Scheduled 503s come out: drain-return deferrals and sticky/placement answers
  to a host's own early retry (host-rate-limited, host-in-flight), each split
  across the minutes its 30 s sample covers.
- The rung budget counts only sustained breaches: two straight minutes over
  max(1.5x, +20) warn, over max(2x, +40) would-block.
- The report carries a paceVerdict over the three pace checks. seal_canary
  downloads the canary cell's report and seals that verdict; a batch below the
  default pace needs PASS, from a report on the same cell that drained at that
  pace.
- Docs: the step-down rule reads paceVerdict, 30 s waits for the lane service
  time (#25645), and the staging step is dropped since staging drains unpaced.

Replayed read-only: 10-01 c29 would-block (9 minutes over 41.5/min); all nine
10-02 cells and 10-01 c25 paceVerdict PASS.

* fix(relay): a partial count already past a block line blocks, in the shadow gate's Cloud SQL and pool checks

A truncated FATAL count is a floor, and one runtime sample over the SQL-failure
line is a fact, so neither waits for a complete read. The waiter-run rule still
needs a complete run, since holes can join two runs into one.

* fix(relay): a canary pace PASS needs a real cohort and whole telemetry; one median-based 503 check

From the final review of #25639:
- canaryPaceVerdict seals PASS only from a report that drained at least 400
  hosts (about half a 10-02 US cell), so a near-empty canary cannot authorize
  a fast batch.
- A director-metrics sub-window with fewer samples than one instance emits
  is unverified, so an empty or short Logging answer is never a calm drain.
- seal_canary names the shadow artifact, report path and cell from the gate's
  normalized cell list, as cell_1 uploads it.
- director503 folds into nonDrain503Budget as a single-minute spike rule,
  max(10x median, 200), dropping the pre-drain peak statistic. All 30 replayed
  windows keep their verdicts.

* refactor(native-chat): keep the provider resume handle opaque to shared code (#24991)

* refactor(native-chat): keep the provider resume handle opaque to shared code

Shared structured-chat code parsed each provider's resume handle: Claude's
session id and branch leaf, Codex's thread id, through a 'claude' | 'codex'
union every new agent had to widen. The in-memory handle is now
{ transport, agent, nativeId, providerData? }: shared readers use nativeId,
lease and handle-chain checks compare transport and agent, and only the
Claude adapter reads its leaf (providerData).

Stored and wire forms are unchanged for Claude and Codex. One encoding
module writes their typed shapes and decodes both those and the neutral
shape a new transport uses, which an older build refuses as unreadable
rather than reading as Codex. Key and root strings, which fork seeds,
superseded creations and resume offers persist, stay byte-identical.

The journal's own handle type becomes the journal-row and attach-wire
encoding of the same handle, and the journal identity carries the
neutral handle (null before the provider proves one).

No user-visible change.

* fix(native-chat): derive journal-row provider handles from the journal identity

The journal row converter now takes the identity every caller already holds,
so a row's handle has one obvious constructor. Tests that wrote the in-memory
handle straight into journal rows now build it through that converter, and the
processless Claude fixture names a not-yet-proved handle as null.

* fix(native-chat): refuse a stored provider handle written in both forms

A typed Claude or Codex handle that also carries the neutral form's
transport, agent, native id or provider data named two identities; it
was read as Claude or Codex and the next write dropped the other one.
Such a row now stays unreadable and is set aside untouched.

* test(native-chat): use opaque handle in queued rejection fixture

* test(native-chat): share one Codex journal identity in the integration suite

Main grew the suite to the 800-line limit; the opaque-handle import pushed it
over. The two tests built the same identity inline.

* refactor(agent-session): name the handle's adapter state resumeCursor

Rename the neutral provider handle's providerData to resumeCursor before any
row persists the neutral form: it is an adapter-owned resume position (Claude's
transcript leaf), never identity. Claude/Codex stored and wire bytes are
unchanged; their typed shapes never carried the field.

State the stored-form contract (a handle's field set is closed; later per-link
data goes on the chain link, which every build preserves) and pin it with a
record round-trip test. Document that transport records the id space the
native id was minted in, which can differ from the agent's current transport.

Cover src/main/{native-chat,claude,codex}, src/shared and every structured-*

default. A lane that exists today now fails loudly if it goes missing; only
the not-yet-landed acp/ and provider-process/ may be absent.

Move the test-only file rule into one classifier shared with the
localization audit, so -test-<thing> helpers and test doubles no longer
enter the production gate.

Export main() so the real-tree tests exercise the entry list CI uses,

* test(native-chat): use production prompt response fingerprints

* test(native-chat): pass journal items to the paired-runtime outbox hook

Main made journalItems a required outbox input; mirror production by
passing the read state's items.

* test(native-chat): pin paired-runtime routing and capability questions

- Move the paired-runtime chat test into its own file and render the real
  session hook against a paired server that advertises today's capabilities
  while this machine advertises none, so Stop, prompt cancel, repeated Stop
  and question answers fail if their capability question goes to the wrong
  runtime. Add a local and a paired session sharing one id.
- Cross-version: state that the file pins the capability strings a
  v1.4.219 server really advertises, use the desktop's real handshake list,
  and keep the current server only as the control for the refusal.
- agent-launch-routing: give the released-server case a capable client so
  it is refused by the server gate, not the client one.

* test(native-chat): route the paired launch suite and cover the outline read

- Start the cross-version job when the launch route or the client list the
  desktop sends a paired host changes, since the paired launch suite runs
  them.
- Check the rail's conversation outline is read from the paired server, and
  narrow the hook test's header to what it covers.

* Extract provider process supervision and stream reading from Codex (#24989)

* Move provider process supervision and stream reading out of Codex

* Preserve teardown behavior with checked mock types after move

* Apply provider launch environment and caller teardown labels

* Give provider child env one owner and gate Codex contract on the shared reader

resolveProviderChildEnv is now the only place that overlays and strips a
provider's environment; the spawn spec and the request-scoped Codex session
both call it. supervisedPosixLaunch only accepts a launch without env fields,
so an override can no longer be silently ignored there. Edits to the shared
stream reader or the env rule now run the real-binary Codex contract job.

* feat(activity): multi-select agent rows with a bulk right-click menu (#25486)

Agent rows in the activity view now select like workspace cards (Cmd/Ctrl-click to toggle, Shift-click for a range), with a bulk right-click menu to mark agents read or unread and clear finished agents. Selection logic and the selected-row style are shared with the workspace list, and right-click menus close each other.

* feat(relay): report lane service times, 503 causes, per-site hold p99 and a director-vs-cell lock-wait split (#25645)

* feat(relay): report lane service times, 503 causes, per-site hold p99 and lock-wait split

Adds the step-1 observability: drain-return and sticky slot service times,
every /v1/assign 503 by cause with a non-drain total, a p99 per lock hold
site (drain-return regional rows get their own site), a director-side
pg_stat_activity sample that splits lock waiters by director vs cell, and
a log line for each reserved_requests drift reconciliation corrects.
Log-based metrics for the new fields are declared in Terraform, not applied.

* fix(relay): classify a lock waiter by the first relay table its statement names

* fix(relay): attribute lock waiters to the root holder; document the director hold alert change

Every waiter after the first in a row-lock convoy is blocked by the first
waiter, so the sample now walks pg_blocking_pids to the root, reading it once
per waiter. The sampler is single-flight. Drain-return regional holds feeding
the non-paging director hold policy is documented as expected.

* docs(relay): note the lock-wait sample undercounts director waiters when the pool is full

* fix(orchestration): give an OpenCode worker its task only once OpenCode can submit it (#25101)

* fix(orchestration): keep pressing Enter until an OpenCode worker's task starts

OpenCode 2 draws its input box before it has loaded its agent list from its
server, and silently drops an Enter that arrives in that gap. On a loaded
machine the gap outlasts the 0.5 s Orca waits after pasting, so a worker's
task sat unsent in the box while worker-start reported it ready.

OpenCode's turn start is now observed through its status hooks, like Codex
and Claude. While no turn has started, the prompt verifier presses Enter
again on an interval (per the agent row, opencode and opencode2) for as
long as the pane's hooks are reporting, never past an approval or question
prompt or a replaced pane, and at most a fixed number of times. A pane
whose hooks never report keeps today's single Enter and unobserved receipt.

* fix(opencode): give a worker its task only once OpenCode can submit it

OpenCode 2 draws its input box, and shows its cursor there, before its agent
list has loaded from its server, and it silently drops an Enter that arrives in
that gap. Orca pasted a worker's task on the box's cursor and pressed Enter half
a second later, so on a loaded machine the task stayed unsent in the box while
the worker read as started.

OpenCode's paste readiness now also waits for the row under the input box
(`<agent> · <model>`), which OpenCode paints only once the agent list exists.
The rule keys on the row's separator inside OpenCode's alternate screen, not on
names or colours. Both the opencode and opencode2 rows use it, worker start and
the renderer's draft paste alike. OpenCode 1 paints the row in the box's own
frame, so it is ready on the same read as before.

Recorded OpenCode 2.0.21 boots (cold, hidden pane, four at once, attached to a
running server) are the evidence; two more show an Enter after the row
submitting and one at the box being dropped. The earlier resubmit loop and the
settlement-provider changes are removed.

* fix(opencode): prove the agent-row signal with natural captures and never paste a draft blind

Replaces three recordings made by launching four OpenCode boots at once with
natural single-run evidence: one cold start that pasted on the agent row and
pressed Enter on Orca's real 500 ms timing (submitted), and one cold start
recorded under heavy load from other sessions, where the paste on the box's
cursor and Orca's Enter came before the agent row and the brief stayed unsent.
Adds a 2.0.14 cold start as a cross-version check.

The renderer's draft paste no longer falls back to a blind paste when the
OpenCode agent-row signal never arrives: OpenCode would drop the Enter and
leave the draft in its box, so the caller gets its timeout notice instead.
Other agents keep the fallback.

* fix(opencode): type the single-signal predicate against the public signals

Co-Authored-By: Claude <noreply@anthropic.com>

* fix(opencode): read the agent row by its place on screen and wait for it only before Enter

- The agent-row signal now keys on structure: the `·` must sit on the line
  directly above the input box's bottom-left corner, so a `·` in the footer
  path or a session tab title no longer counts. Leaving the alternate screen or
  turning bracketed paste off withdraws what each part established.
- Only deliveries that press Enter wait for the row (new
  `submitPasteReadySignal`); drafts keep the box-cursor rule, as on main.
  Worker start always submits.
- When the box cursor has shown but the row never comes (OpenCode 2 drops the
  agent below 44 columns), both waiters proceed after a 5 s grace, as main
  did. A natural 40-column capture proves that start submits.
- The renderer's blind-paste fallback is back to main's behaviour.

Co-Authored-By: Claude <noreply@anthropic.com>

* fix(opencode): take the box at the readiness deadline while the agent-row grace is pending

- Both paste waiters resolve ready, not timed out, when the hard deadline
  lands while the 5 s grace is pending: the box was seen, so this is the
  verdict the box rule gave before.
- Tab-bound draft paste is tested to wait on the agent row only when Enter
  follows.
- Scanner: a separator pairs with its corner only inside one synchronized
  frame, row 0 clamps to 1, and the grace comment names the transparent-theme
  case. The draft signal type no longer admits the agent-row signal, whose
  grace only the paste waiters honour.

Co-Authored-By: Claude <noreply@anthropic.com>

* fix(opencode): withdraw the agent-row grace when OpenCode leaves the alternate screen

If OpenCode exited after drawing its box but before its agent row, the grace
still ran out and the task was pasted into the shell. Leaving the alternate
screen now clears the box cursor, and once an app has left it a cursor the
shell shows outside it no longer starts a grace. A terminal that never
forwards the alternate screen still gets one.

* test(serialize): register the new OpenCode captures' pre-existing grid-restore counts

The six OpenCode 2 captures this PR adds hit the serializer limitations the
1.18.32 and 2.0.18 captures are already registered for: the live pen's
background (and once its bold bit) on restored cells, rows kept below the
source after a shrink, and the cursor one column short after a shrink. No
I1 or I3 failure; the serializer is unchanged.

Co-Authored-By: Claude <noreply@anthropic.com>

* fix(opencode): bound the readiness deadline's last settle check

With a grace pending, the deadline runs one more settle check, and over SSH
its foreground read could hold a past-due wait for the channel's 30 s
timeout. It now gives up after 2 s. Tests cover a hand-off, a failure and an
abort during that check, a refused grace settled at the deadline, the bound,
and the grace restarting at a hand-off.

* fix(ci): unblock main's static analysis after the nested-worktree delete dialog (#25683)

* fix(lint): merge the duplicate worktree/removal import in the delete-failure toast

* fix(i18n): add the nested-worktree delete dialog's strings to the English catalog

* feat(relay): one-command director deploy driver (#25642)

* feat(relay): add an operator-local driver for director deploys

One command runs the audited director deploy: preflight, pause rehome if
enabled, publish, deploy, optional cell configure, a digest-bound inspect,
the monitor dry-run, and re-enable. It only dispatches the existing
workflows, reads the published digest from the registry and the run log,
reads the monitor verdict from its sealed state, and enables with the
digests gcloud reports after the deploy. It stops at the first failure,
records state, and resumes from it.

* fix(relay): report and own the rehome pause; operator types every phrase

- Read the control back from pause and enable runs whatever their conclusion,
  and report PAUSED or UNCONFIRMED loudly.
- Resume re-enables only the pause this driver recorded (generation and run).
- Ctrl-C and SIGTERM print the same state and resume report.
- The operator types every workflow confirmation. A 5-minute soak gated on
  director 5xx runs before configure.
- A dry run keeps no state file. The quiet check pages through all runs.
  Run IDs come only from the printed URL. One step table drives execute,
  dry run and resume. The monitor verdict reuses verify-authority.

* fix(relay): read back only the driver's own rehome run; anchor the soak at the traffic switch

- The pause and enable read-back accepts only the control line its own step's mode prints, at the
  generation its own dispatch expected. A run adopted after a crash is settled even when green.
- The soak window opens a minute before the deploy run completed and is read a minute after it
  ends, for log ingestion lag.

* fix(relay): say what typing ENABLE_REGIONAL_REHOMING commits to

* fix(relay): the ENABLE prompt also names the 150 s evidence budget

* refactor(relay): derive every deploy decision from live state; no resume machinery

The driver keeps no state between runs. Each run reads the serving
director, its configured cells and the rehome control, and skips what is
already done.

- The only rehome fact it owns is the run that paused rehome. A re-run
  names it (--pause-run), and the driver checks it against that run's log
  and the live generation.
- A recover-enable line counts as the driver's own pause only with
  recovered: true. A director safety pause is never adopted (F3).
- Publish runs before the pause. A fresh run that finds rehome paused
  stops unless given --pause-run or --rehome-disabled (F2).
- Interrupts report a pause or enable still in flight as REHOME IS
  CHANGING (F1). PAUSE UNCONFIRMED and ENABLE UNCONFIRMED are distinct.
- A tripped soak is judged again on fresh traffic (F5). SIGHUP is
  handled, and a pending signal stops the driver before its next dispatch.
- Every stop prints the single command that finishes the deploy.

Removes the state file, --resume, step statuses, monitor adoption and
interrupted-dispatch adoption.

* fix(relay): never report done over an unexplained pause; prove pause ownership by actor

- G1: always read rehome; no early DONE.
- G2: --pause-run must be a rehome-control run by the same user.
- G3: a failed enable run is never an enable.
- C1: a pause or enable is reported as changing from the moment it is
  dispatched.
- C2: --leave-rehome-paused (was --rehome-disabled) refuses an enabled
  switch. Every printed command parses.
- G4: the enable-in-flight report prints both finishing commands.
- G5: the driver's own runs never block the quiet-lane check.

* test(relay): port the round-3 probes: hard kill mid-pause, unexplained disable after a failed enable

Claude-Session: 1145a80d-dec4-4a9b-9373-bbbb876b9041

* fix(test): build the stop-note test's Codex provider handle with codexProviderHandle (#25706)

* feat(native-chat): publish where each submission was sent and the turn a stopped one was answered into (#25073)

* feat(native-chat): publish each submission's journal positions

A client never learned where in the journal a send was accepted or taken back,
so drawing a stopped send had to guess from its own row and from clocks, and the
guesses misfired after restarts. Each projected submission now carries
`submittedSequence` (its submission row) and `resolvedSequence` (the dispatch row
that resolved it; absent while pending): two optional fields, computed on every
fold from rows already stored, never stored themselves. Older clients ignore
them. The failure-fact schema moves to its own module to keep the journal schema
file within its size limit.

* test(native-chat): pin a submission's resolved position on the provider-echo accept path

Also say which rows can resolve a submission, and that the submission schema, not the shared type, omits acceptedSequence.

* refactor(native-chat): publish only where each submission was sent

A rejected send's own row now moves to its rejection (#24710), so the row that
resolved a send is the item's own position and needs no second copy. Keep
submittedSequence, the one journal-order record of where a send was sent.

* feat(native-chat): publish the turn a withdrawn Codex send was answered into

A send Codex answered into a turn that then ended without taking it is
rejected by that turn's end. The rejection row now names that turn's
record, and the submission carries it as answeredInTurnItemId, so a
client can tell which turn the send belonged to without guessing from
journal order or clocks. Absent on every other send.

* feat(native-chat): say how a withdrawn Codex send joined the turn it names

The answered turn becomes { turnItemId, via }: 'start' when Codex
answered the send's turn/start with that turn, 'steer' when Orca steered
it into that running turn. A client can then tell the turn's opener from
a send steered into it even when the opener is on an older page.

* feat(native-chat): state on every rejection whether it names a turn

A rejection a host writes now always carries answeredInTurn: the turn
Codex answered the send into, or null for none. A reader can then tell
'answered into no turn' from a row written before the field existed,
which keeps no answer and is placed by the older rules.

* refactor(native-chat): give the answered-turn schema its own module

Keeps the journal schema file within its line limit.

* docs(native-chat): say an unreadable answered turn reads as none

* test(sidebar): cover disk reloads and concurrent UI writes

* fix(test): construct submission-position Codex provider handle correctly

Subject: [PATCH 049/167] fix(omp): stop the tab spinner sticking after
 subagents finish (#23662)

* fix(omp): settle the pane after late or leaked subagents

Wake turns started after the root reported done, ids that never settled,
and task-session copies of the extension all left the tab spinning.

Fixes #22854

* fix(omp): keep pane ownership on the subagent roster

Ownership is per event bus, so it has to survive a factory re-run on the same bus.

* test(omp): assert the reload case settles on the child's completion

* fix(omp): keep tracking children across root runs

Clearing the roster on agent_start dropped live children, so Esc or a woken
helper could mark the tab done early. Also drops the now-unused reset helper.

* fix(pi): only re-arm a completion that was already posted

A child starting between a run's end and its settle took that run's done,
leaving the pane on working when the settle came.

* fix(omp): settle a child that finishes before the first root run

After a resume, a woken helper could finish before any run posted a done, leaving the tab spinning.

* fix(omp): keep a mid-turn reload from settling the pane on a child's completion

The generation-0 clause treated "this factory run has not seen a turn" as
"the pane is idle", but an in-process extension reload resets those counters
while the root run is still working. A child starting and finishing in that
window then posted agent_end, so the tab read done while OMP kept working.
Track the root run on the roster, which survives a reload, and only re-open a
completion when no run is in flight.

Subject: [PATCH 050/167] fix(daemon): bump the terminal daemon protocol to v40
 (#25291)

* fix(daemon): bump the terminal daemon protocol to v40

Daemon-side changes landed under v39 after v1.4.220 shipped v39: the #25130
and #24636 shell-wrapper changes and a wider agent list (jcode, qoder-cn, dsb;
resume claims for qoder-cn, qwen-code, cursor and jcode). Without a bump, an
update keeps new tabs on the running v39 daemon, which misses the wrapper
fixes and rejects those resume claims with agent_session_identity_required.

* fix(local-builds): record daemon protocol v40 in the local build compatibility contract

Subject: [PATCH 051/167] fix(test): use the current provider handle shape in
 the submission-positions test (#25709)

#25073 built the test's journal identity with the retired { kind, threadId }
provider handle, which the node typecheck rejects (TS2353). Same fix #25706
made in the stop-note test.

Subject: [PATCH 053/167] feat(browser): add an eraser to screenshot markup
 (#24801)

* feat(browser): add an eraser to screenshot markup

Click or drag across marks to remove them whole, one undo step per drag.

Fixes #23258

* fix(browser): drop the in-flight markup gesture on undo and redo

Undo mid-erase left marks hidden against the restored drawing, so release removed them and cleared redo.

* fix(browser): settle a markup gesture whose release was lost

A gesture now blocks any new press so a second finger cannot steer it.
If its own release never arrived, that block also swallowed the next
press from the same pointer, so the next drag continued the stale
gesture: a stroke jumped from its old end, and an erase swept from the
old point, removing marks along a line the user never touched.

A pointer cannot press twice without releasing, so a press from the
gesture's own pointer now settles the old gesture as its release would
have, then starts the new one.

* fix(browser): an eraser click takes only the top mark, a drag takes all

A click on overlapping marks now erases only the one drawn last, matching
what a user expects from pointing at a mark. Once the pointer really moves
the press becomes a drag, whose first sweep starts at the press point, so
every mark under it and along the path is erased. A move that reports the
press point again does not turn a click into a drag.

* fix(browser): undo mid-gesture takes back only the gesture

Undo pressed while a stroke or an erase is still held now drops just that
gesture, as the newest step; the committed marks are untouched, so the next
Undo takes back the last of them. Redo and Clear drop the gesture, then apply
as before. With the gesture gone, the rest of that drag neither draws nor
erases until the next press. Undo is enabled while a gesture is in flight,
since it now has something to take back.

* fix(browser): keep an eraser tap a click within a 4px slop

A touch or pen tap often reports a move a fraction of a pixel from the
press point. The eraser treated any move to a different point as a
drag, so such a tap erased every mark under the finger instead of only
the top one. The erase gesture now records its press point and a
pressed/dragging phase: it stays a click until the pointer travels 4 CSS
px, then sweeps from the press point as a drag.

* fix(browser): undo over an empty erase undoes the last mark

Pressing Undo while an eraser was held over empty space only dropped
the erase, which had hidden nothing, so Undo looked dead and the Undo
button was enabled for a step with no visible effect. Undo now treats
a held gesture as a step only when releasing it would change the
markup (a stroke being drawn, or an erase that hides at least one
mark). Otherwise Undo takes back the last committed mark and ends the
erase; with nothing to undo it leaves the erase alone. The Undo button
is enabled exactly when pressing it would change something.

* fix(browser): redo with nothing to redo keeps a held markup gesture

The Redo button is disabled when there is nothing to redo, but the
Cmd/Ctrl+Shift+Z shortcut is not. Pressed while a stroke or erase was
held down, it replaced the document with itself and dropped the
gesture, so the stroke or erase silently stopped. Redo now leaves the
state untouched when there is nothing to redo. Clear still always
drops the gesture.

* fix(browser): discard a markup gesture whose pointer was cancelled

pointercancel was wired to the release handler, so when the system took
a touch or pen pointer away mid-gesture (an OS gesture or palm
rejection), the stroke was saved and an erase was applied as if the
user had lifted deliberately. pointercancel now discards the in-flight
gesture owned by that pointer: the stroke is not saved and the marks an
erase was hiding come back, with no undo step. Lost pointer capture and
a press that reveals a missed release still commit, since both stand in
for a release that did happen.

* test(browser): pin that losing the pointer commits a markup gesture

The canvas commits a stroke or erase when it loses pointer capture
without a release, so a gesture can never be left open. No test covered
that wiring: removing it, or routing it to the cancel handler, left every
test green. The new test ends a stroke with only the lost capture and
checks that Undo then leaves it to redo, which only a committed stroke
does.

* fix(browser): do not save a markup shape pressed without dragging

A Rectangle, Ellipse or Arrow press released without dragging paints
nothing, but it was saved as a zero-size mark. With the eraser, a click
takes only the topmost mark, so that invisible mark made the next eraser
click on a visible mark at the same spot appear to do nothing. It also
added an undo step with no visible effect, and while such a press was
held Undo was enabled but only dropped the invisible shape.

A shape with no size is now not saved, and a held unmoved shape press
is not something Undo takes back. Pen and Highlighter taps still save
the dot they draw; text is unchanged.

* test(browser): drop a cancelled-stroke test the overlay test already covers

MarkupOverlay.test.tsx drives the same press, move, pointercancel and
following lost capture through the real canvas wiring and asserts Undo
stays disabled, which already proves nothing was committed or held.

* docs(browser): note the erase drag re-rasterizes the markup layer

The committed layer now renders the visible marks, so an erase drag
re-rasterizes it once per newly hit mark; the comment said never.

Subject: [PATCH 054/167] fix(native-chat): a sent image no longer flickers to
 its "Pasted image" placeholder while the agent works (#25664)

* fix(native-chat): a sent image no longer flickers to its "Pasted image" placeholder while the agent works

The thumbnail's blob URL lease and its release effect were keyed on the
runtime-context object, which the owner hook rebuilds with equal values on
unrelated store updates. Each rebuild revoked the URL the <img> was showing.
Key both on the image cache key instead.

* test(native-chat): cover each half of the equal-context image fix; drop releaseLocalImageSrc

Hook tests: an equal runtime-context rebuild keeps the pin and URL; an SSH
reconnect or worktree change re-reads. Transcript test: an equal rebuild
leaves an off-screen image's cached entry alone. releaseLocalImageSrc had
no production caller left; tests now release by cache key, and the rich
markdown test releases the key the editor actually leases.

Subject: [PATCH 056/167] feat(editor): highlight Quarto and R Markdown files
 (#17772)

Highlight Quarto and R Markdown documents using the bundled Markdown, YAML, R, Python, and JavaScript tokenizers. Preserve guarded startup registration and bound inherited inline embed recursion.

Thanks to Yoshihiko Kunisato (@ykunisato) for the implementation and regression tests.

Fixes #17771

From 9f561703b70409e62e234a346d9228458b6a6af5 Mon Sep 17 00:00:00 2001
From: Ryosuke Matsui <pinelibg@pm.me>
Date: Tue, 6 Oct 2026 09:18:33 +0900
Subject: [PATCH 057/167] fix(i18n): fix garbled Japanese name suggestion and
 reversed ja/zh quotes (#25255)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* fix(i18n): use opening quotes in ja/zh concatenated labels

The Browser Use / mobile emulator prompt examples and the workspace-name
row wrap text in separately translated opening and closing quotes, and
ja/zh mapped the opening one to the closing mark, rendering 」text」 and
”text”.

* fix(i18n): make the Japanese workspace-name row read in Japanese order

The row concatenates Use / quote / name / quote / as workspace name in
English order, so ja rendered 使用「name」ワークスペース名として. Swap the
two word fragments so it reads ワークスペース名として「name」を使用 without
touching the component; a full-sentence key (#9294) would also need the
emphasized name split out of the translated string.

* fix(i18n): give the grab sheet's accessible-name quotes separate keys

Both quotes around the accessible name shared one key, so locales with
distinct opening and closing marks could only render one of them twice
(ja: 」name」, zh: ”name”). A separate opening key lets them render
「name」 and “name”.

Subject: [PATCH 058/167] fix(native-chat): an unsent draft survives a reload
 or quit (#24905)

* fix(native-chat): an unsent draft survives a reload or quit

The composer's draft text, its editor document and settled image refs lived
only in module memory, so a reload, quit or crash lost whatever was typed,
including text a Stop had just given back. They are now saved per pane scope
in localStorage: typing is debounced and flushed when the window hides or
closes, text given back to the composer is saved at once, an emptied or sent
draft is removed at once, and only the newest drafts within the composer
caches' existing bound are kept.

* fix(native-chat): save draft images outside the state updater

* fix(native-chat): one store owns each unsent draft

The draft's text and its image chips were saved by two writers that each
rebuilt the stored record from what storage held, so a draft that once went
over the size cap, or one refused write, lost its images on the next save.

One store now holds each composer scope's whole draft in memory and writes
storage from it: typing is coalesced, returned text, chips and clears land at
once, a refused write stays pending for the next flush, and all drafts
together keep to a budget so the outbox can still save a send. Closing a tab
drops its panes' drafts.

* test(native-chat): returned text is stored before its images arrive

* fix(native-chat): keep returned text and drop launch-seed copies across reloads

A message given back from the outbox could be larger than one draft was
allowed to store, so the saved draft was deleted and the returned text was
gone after a reload. One draft may now use the whole draft budget, which
holds the largest message a send accepts.

An adopted launch link is also parked in the agent's input line. Restoring
it after a reload, with no seed left to replace that copy, typed it twice,
so the untouched copy is shown but not saved.

A composer reused for another pane now shows that pane's images, so adding
one never saves the previous pane's over them.

* test(native-chat): a plain 260k given-back message stays saved

* fix(native-chat): saved drafts drop pasted images and die with their worktree

A pasted image lives in a temp file Orca wrote, and the permission to show
it is held in memory only, so after a restart a restored pasted chip showed
a generic icon, and once the temp file was cleaned it looked fine but the
send failed after the composer cleared. Pasted images now stay in the
draft for the current run only; images the user attached from their own
files are still saved.

Removing a worktree now deletes its terminal tabs' drafts, as closing the
tab does.

A paste that finished late in a composer that had already been replaced
wrote that composer's old images back over a newer send. Dropping a
placeholder chip no longer writes the saved draft.

The pane-change reload in the images hook is removed: the composer is
keyed by pane, so a pane change always mounts a new one.

* fix(native-chat): the composer renders the draft store instead of keeping a copy

A composer that had been replaced, for example by a question prompt, could
still finish an attach or a send later and write its own old copy of the
draft over the store, so a sent message or image came back. The composer
now reads text and images from the draft store and changes the draft as it
is now: an added image or file reference joins what is there, and a send
that settles after a round trip, or after its composer was replaced, clears
the draft only if it is still what was sent. Only chips still being written
and an IME composition in progress stay local to the composer.

Closing a tab now deletes drafts by the exact tab id: a second chat for one
session has an id that extends the first one's, so a prefix match deleted
its drafts too.

* fix(native-chat): keep images pasted during a command and on shown composers

An image pasted while /compact or /clear was still on its way to the host
vanished when the command was accepted: the clear that followed also wiped
the chip still being saved. A command that settles now clears only the
draft it sent, and an image pasted meanwhile stays.

A composer on screen could lose its pasted images, and its unsaved launch
text, once 128 other drafts pushed its record out of memory, because those
are never stored. A draft that a composer is showing is no longer evicted.

* fix(native-chat): a draft being written is never evicted from memory

A write to a pane while every other cached draft was on screen could evict
the record it had just written, losing it. Also adds the test that a send
settling after its composer unmounted clears the saved draft, through the
real send hook.

* fix(native-chat): restored images Orca couldn't keep come back to attach again

A pasted screenshot in an unsent draft vanished after a restart with no
notice, and a restored image whose file had been deleted looked fine until
the send failed. Both now come back as a placeholder chip that names the
image and says it wasn't saved with the draft. Send stays disabled, and
the send button says to attach the image again or remove it. Attaching a
file with the same name takes the placeholder's place.

Two browser tabs of the web client on one chat now follow each other: when
one sends or edits the draft, the other drops its copy and shows the new
one, unless it has an edit of its own not yet saved.

* test(native-chat): no send while an image waits to be attached again

* fix(native-chat): pasted images in a draft come back after a restart

A pasted screenshot lived in the OS temp folder with a read permission held
in memory, so a draft could only bring it back as a placeholder. Local
pastes are now written to Orca's own native-chat-pastes folder under the
app's user data, and a draft keeps them as real images. On restore the
composer asks the main process to re-grant each one; main grants a read
only when the file's real path, symlinks and junctions resolved, is inside
that folder, and reports anything else as not kept, which becomes the
placeholder. Pastes older than 30 days are deleted at startup, far past
the host's 24 hour window for a resent message; the sweep never follows a
link and never blocks startup. SSH pastes and older temp-folder pastes
still come back as placeholders.

* test(native-chat): the paste sweep test ages the link itself

* fix(native-chat): type the paste-folder path helper with PlatformPath

* fix(native-chat): type the paste-folder path helper from path.posix

* fix(native-chat): placeholder chips say what happened and only a user attach replaces one

A placeholder now shows the image's name and a short hint on the chip
itself, "Attach again" for a file and "Not kept" for a pasted image, with
the longer explanation in its tooltip. The copy no longer says the image
wasn't saved: it says it couldn't be brought back, and for a pasted image
it asks only for removal, since a new paste can't match it. The send
button now says to remove the image to send.

Only an image the user attaches (picking, dropping or pasting) takes the
place of a placeholder with its file name. An image Stop gives back is
added beside it, so a different file with the same name no longer hides
the reminder.

* fix(native-chat): only composer pastes use the paste folder, and restore grants only real paths

Every local clipboard image save had moved into the paste folder, whose
macOS path has a space, so a screenshot pasted into a terminal or sent to
a terminal-backed agent no longer attached. Only a native-chat composer
paste goes there now, through an optional field on the existing save
call; terminal, editor and phone pastes stay in the system temp folder as
before. An image path sent to an agent's input is escaped the way a
dropped image is.

The restore re-grant now grants only the file's real path, and only when
both the real path and the path as written are inside the paste folder,
which must not itself be a link. The sweep deletes only Orca's paste
files and skips a linked folder.

* fix(native-chat): a restored paste is readable by the path its draft stored

Restore granted only a paste's real path, but the composer reads the
preview by the path its draft stored, so with user data reached through a
link the restored chip showed a generic icon. The stored spelling is
granted too; it is already proven to sit inside the paste folder. A test
also pins that a composer paste asks for the paste folder.

* fix(native-chat): grant a paste's stored spelling only when it names the same file

A grant also covers its path's own real path, so a stored spelling that is
itself a link inside the paste folder could have granted an outside file
while the path as restored reached a real paste. The stored spelling is
now granted only when it resolves to the same file; otherwise only the real
path is, and the preview falls back to the generic icon.

* test(native-chat): check the outside file by its real path too

* fix(native-chat): a structured chat's draft belongs to its conversation

Drafts of a structured chat were saved under the pane (tab id plus a hash
of the session), so the follow-up that keys them by conversation would
have left every draft saved by this build invisible after an upgrade,
never shown and never deleted. They are now keyed by the conversation
(`agent-session:<sessionId>`) from the start: every composer showing the
conversation shares one draft, Stop and a queued card's Edit give text
back to it, closing the tab keeps it, and removing the worktree deletes
it. Terminal-backed chats keep the pane key and lose their draft when the
tab is closed.

A send now leaves whatever was added since it was sent, text typed or
composed and images attached meanwhile, and clears only what was sent;
a draft replaced in the meantime is left alone.

Lifted from #25207 (62ef8e78042): the conversation key, the composer's
draftScopeKey, keep-on-close and delete-on-worktree-removal, and the
leave-what-was-added send settle.

* fix(native-chat): every path that drops a worktree's tabs deletes their drafts

A worktree's chat drafts were deleted only by the removal's own renderer
teardown, which looked them up from the worktree's tab lists after the
removal round trip. The host announces the change before it replies, and
the listing refresh that starts can purge those tab lists first, so the
teardown found no tabs and the drafts stayed. The bulk purge now deletes
the drafts of the tabs it drops, and the teardown deletes them before it
closes any tab.

* fix(native-chat): only a user's delete removes a workspace's chat drafts

The listing purge is reconciliation, not a delete: re-pairing a server under
the same id purges its worktrees' tabs, and the host then restores the same
chats under the same draft keys, so deleting drafts there erased them.

Removing a worktree, a project or a folder workspace now reads the draft
keys of the workspace's open chats before the host round trip, and deletes
them only once the host confirms. A listing refresh that drops the tabs
during the round trip no longer hides them, and a refused delete keeps them.

* feat(native-chat): drafts live in IndexedDB with no budget, and a refused save shows

Unsent drafts shared localStorage with the send outbox, so they kept to a
128-draft, 1M-character budget and the oldest quietly did not come back.
They now live in their own IndexedDB store, all loaded once at startup,
with no budget and no eviction.

- Startup waits up to 1.5 s for the load alongside the session read; a
  slower load still fills in every draft not edited meanwhile.
- Each write commits explicitly; on pagehide, beforeunload and hiding,
  anything storage has not confirmed is also journaled synchronously to
  localStorage and replayed by the next run.
- A BroadcastChannel replaces the storage event: another window's save is
  taken unless this window has a change of its own not yet saved.
- A refused save is retried on the next flush and shown: a warning icon
  by Send and on the draft's image chips, only after a refusal.
- Each draft records the workspace and host it was written in, so removing
  a worktree, project or folder workspace also deletes the drafts of chats
  whose tab was closed earlier.

* fix(native-chat): drafts set from the store are never saved back, and early appends merge

- The editor no longer saves a value the field sets from the store (a
  late-loaded or adopted draft): that echo made another window's draft a
  local change here, so a send in one web tab came back from the other.
  A whole draft set on the editor uses its saved document, keeping its
  skill chips. Equal documents no longer count as a change.
- Text or images given back, or attached, before the startup load lands
  are added to the loaded draft instead of replacing it; only typing wins.
- The unload journal leaves out drafts already refused, keeps to 256,000
  characters, and drops a draft's entry once any window confirms a change
  to it, so a replay never brings back a draft sent since.
- A failed load is retried three times with backoff, warned about once,
  then left.
- Adopting another window's write keeps images already checked, so their
  chips don't flash.
- A refused draft shows one icon, by Send, with plainer copy; the chip
  badge and its string are gone.
- A comment that said drafts' bounds retire orphans is corrected.

* test(native-chat): an early append the load already read is not added twice

* test(native-chat): the store-value editor test waits for the editor and checks no document is saved

* fix(native-chat): early appends are read-modify-writes, and the load can't be skipped

- Before the load lands, an append (text or images given back, a paste)
  reads the stored draft and writes it back with the append in one storage
  change, so a load that failed and was retried can never lose the saved
  draft. On landing, only appends that load could not have read (made after
  it began reading, or never written) are applied again, by in-run order
  rather than by comparing clocks.
- The editor saves a value set from the store when this window has a change
  of its own behind it, so a mention accepted next to a skill chip keeps the
  chip; another window's draft or a late load still isn't saved back.
- A refused draft is journaled again; the 256,000-character cap bounds it.
- The draft load starts before the startup chain, and the first write
  starts it in a window whose startup never did; startup still waits for it
  before the session's tabs mount.

* fix(native-chat): text given back is durable before its source is deleted

Draft writes reach IndexedDB asynchronously, but Stop's restore and a queued
card's Edit delete their source (the outbox entry, the card) right after
adding the text to the draft. A crash before the write committed lost it.

An addition (text or images given back or attached) is now journaled to
localStorage synchronously, as data, the moment it is made, and dropped
once storage confirms a change at least as new. The next run replays it onto
the stored draft only when storage doesn't already hold it, and only where
the draft doesn't already end with that text or hold that image, so a crash
either side of the commit gives the text back exactly once and resends
nothing. Only earlier runs' entries are replayed.

The append reports whether the addition is durable. Edit, when it isn't
(the journal full or refused), deletes the card only once the draft is
saved, and keeps it if storage refuses. Additions may grow the journal to
800,000 characters; whole drafts still stop at 256,000.

* test(native-chat): a kept paste is readable by the composer preview through chat-image access, with no grant

* fix(native-chat): a per-scope write confirm, and the paste rule as C2 has it

- nativeChatComposerDraftWriteSettled(scopeKey) settles once every write of
  that scope issued before the call has: true only after IndexedDB completed
  each transaction (an append made before the load landed included), false
  when one was refused or failed, and never on a timeout. A change still
  waiting for its deferred write is issued first.
- A queued card's Edit deletes the card only on true, and keeps it on false.
- A restored paste is kept when its real path is a file inside Orca's paste
  folder, as C2 resolved it. The tests keep every containment case and now
  check that neither an outside file nor the file a stored spelling names
  becomes readable through the preview's chat-image access, which reads only
  image files and needs no grant.

* test(native-chat): the per-scope confirm settles at the IndexedDB transaction's complete, and false on abort, for an append before the load

* fix(native-chat): a journaled removal always fits, and a load replays only what preceded it

- A removal is never capped in the journal (it is tiny, and it is what
  keeps a sent draft from coming back); only whole drafts count against
  their 256,000 characters, and additions keep their own 800,000.
- A load replays the journal as it stood when the load began reading, so an
  addition a live window journals later, whose own write is ordered after
  that read, isn't replayed over its newer typing.
- A lifecycle test no longer says the paste is re-granted.

* fix(native-chat): a chat with a draft is never reused or taken over

#24917's empty-chat check read the composer draft under the pane key, while
this branch keeps a structured chat's draft under its conversation key, so a
chat holding typed or given-back text, or only an image, read as empty: a new
chat could reuse it and another request's text could go into it. It reads
the conversation's draft now, as C2 adapted it (d4e469b697b), with the tests
moved to that key.

While the startup load of saved drafts is still running, no chat reads as
empty: one may hold a saved draft memory doesn't have yet. The cost is only
that a new chat opens instead of reusing one during that moment.

* fix(native-chat): a returned text counts as already there only as its own paragraph

Replaying an addition after a crash skipped it whenever the draft merely ended with its text, so
"go" given back onto "please go" was lost. It now counts only when the draft equals the text or
ends with it after a blank line. A whitespace-only draft counts as empty when text is added, and
an addition made before the startup load lands is made again on the loaded draft only where that
draft doesn't already hold it.

* fix(native-chat): a hand-back the draft already holds stays safe until that draft is saved

After merging main's shared returned-text rule, a hand-back the draft
already ends with changes nothing, so it wrote no backup entry yet
reported durable. If the draft holding that text was not saved yet, a
crash after the source copy was deleted lost it. Journal the addition
whenever the draft is not confirmed saved.

* fix(lint): import worktree removal names once in the delete failure toast

Main's #25668 imported from shared/worktree/removal twice in this file,
which fails the type-aware lint gate (no-duplicate-imports) for every
branch that merges current main.

Subject: [PATCH 061/167] feat(orchestration): a native chat gets the
 orchestration pointer a CLI agent gets, through the same send as your
 messages (#25078)

* feat(orchestration): agent mail to a busy chat waits in the chat's own queue

A mail notice for a busy structured chat used to wait in the orchestration lane's
own invisible "until the chat is free" gate. It now goes through the queue a
person's message uses: sendAgentTurn(..., { delivery: 'queue', source }) makes
the host hold it as a draft card the person sees and can Steer or delete, and
the queue sends it when the turn ends.

- The lane's busy gate (turnRunning / awaitingHuman) is gone; the queue's own
  hold decides. Its parking now only waits for its own send or card to settle.
- A queued card's hand-off (sent under a fresh id) is matched by
  queuedMessageId, so it stamps the mail once and never sends a second notice.
- A card from before an Orca restart is still the lane's: no second card.
- A card the person deleted counts as handled for that batch; newer mail
  notifies again. No stored flag: read off the card and delivered_at.
- `orchestration check` waits for the lane to withdraw a card whose mail it
  read, so a stale notice is never sent; more mail replaces the card.
- Each card records who queued it in queued_messages.source_json (versioned,
  schema-validated): the person, or Orca for agents, with every distinct
  sender as an orchestration party plus host id, and the mailbox, dispatch,
  run and message ids. The restart pause holds only the person's cards.
- sendAgentTurn answers with a snapshot, not the journal's live submission.

* test(orchestration): type the mail fixture as a pointer batch message

* fix(orchestration): the queue judges an agent's mail notice as it sends it

A mail notice queued in a busy chat could go out stale or twice: it was
kept true from outside the queue, by orchestration check withdrawing it,
which missed other readers, raced an attempt in flight, lost the card
when /clear carried it (a second notice), and moved it to the back when
new mail replaced it. An agent's card behind a person's paused card never
sent after a restart, so an unattended coordinator stalled.

- The drain asks the card's sender, in its own serialized step, whether
  it still stands: send, restate (count and senders of the mail owed
  now, written onto the card in the hand-off's transaction), or withdraw
  as the host. A failing judge sends as written. Send-now restates but
  never withdraws. Orchestration registers the judge on the host.
- check no longer touches any queue (back to main); onMailRead,
  notifyOrchestrationMailRead and the lane's withdrawals are gone.
- One unsettled card per agent message, enforced at insert; new mail is
  counted when the card sends, never replaces or moves it.
- The lane finds its card by what it is (a notice for the mailbox in the
  session the mailbox reaches now); a decline is a withdrawal a person's
  operation stamped. /clear moves agent cards as the host. Pointer rows
  last only while a direct send is in flight and end with the session.
- Pauses (restart, Stop, /clear) hold only a person's cards, and a held
  card never traps an agent's card behind it, keyed on the message kind.
- The source is named for the message (agent-session-message-source),
  one payload shape per message kind, no relative host id.

* fix(orchestration): Orca's mail notice waits in the queue out of sight

The notice card read as something the person typed and came and went on
its own, the transient-state message the queue should not show. It is
hidden until B can label who sent it.

- The host leaves mail-notice cards out of the published queue, so the
  list, its count, Steer/Delete/Edit, steer-newest and the paused header
  never see them, on every client. Keyed on the message kind: D6's task
  card will be shown, labelled, in B. They still count toward the queue
  limit (temporary, until B).
- A refusal no longer returns a hidden card for the person to act on:
  the host withdraws it, and the lane points again only after a turn ran
  since, the rule it already had for a refused notice.
- Send-now no longer restates a card: no one can reach a hidden one.
- The stored sender drops the pane key, a mailbox credential.
- The gate covers an abandoned worker: a mailbox that reaches no session
  withdraws its notice (tested).

* fix(orchestration): a hidden mail notice never waits on the person

Hiding the notice left three paths where it waited on someone who
cannot see it.

- A failed hand-off write put a send_failed hold on it, which only a
  person's Send or Delete clears: that mailbox's notices stopped for
  good. The host now withdraws a hidden card instead and hands its
  mailbox back to the lane through the ordinary redrive, since an idle
  chat gets no other edge. A write that keeps failing is retried once
  per edge.
- A person's Stop while the agent started on the notice put it back to
  waiting, where no pause holds it, so it was sent again at once. The
  host now withdraws it; the lane points again after a turn ran or when
  newer mail makes it a different notice, as on main. A restart still
  puts it back.
- A notice queued before the person's message went first. One order
  rule now: the person's cards go in order and never past one waiting
  on them; a card they cannot see never delays one they can, and goes
  only when none of theirs may.

The drain moves to its own module (structured-agent-session-queued-
drain.ts). Comments that still described the notice as visible are
corrected.

* fix(orchestration): an accepted notice hand-off stamps its mail; a judge that cannot look decides nothing

- When the agent opened its mail in the notice's own turn (the normal
  flow), an open batch left nothing owed, so the lane never marked the
  mail the accepted hand-off carried as delivered, unlike an accepted
  direct send. The lane now stamps exactly the ids a handed-off notice
  carried whenever undelivered mail remains, owed or not. A later
  conversation is no longer told again about mail already opened.
- At quit the host registry is cleared before teardown, so the drain's
  judge could not resolve the mailbox and withdrew the notice. A judge
  that cannot read its inputs now defers: the card waits for a step
  that can look. A mailbox that resolves to another session or none is
  still withdrawn.
- The judge, the owed-batch selection and the notice body move to
  structured-mail-notice.ts. A failing hand-back of a dropped card is
  logged.

* refactor(orchestration): a chat receives the agent's mail itself, queued like a person's message

A structured chat used to get a derived "You have N orchestration messages,
run check" notice, which could go stale while it waited in the chat's queue,
so the queue judged, restated or withdrew it as it sent. It now gets the mail
itself as the turn, through sendAgentTurn with delivery 'queue', the path a
person's message takes.

- One turn per mailbox batch: the mailbox's unread mail at delivery, in mail
  order, each message led by "[message from <sender>]", its type, subject,
  body, payload and reply hint (what check prints). Mail arriving while that
  card is still in the queue waits for the next card; a card is never edited.
- An idle chat takes it at once; a busy one queues it as an ordinary card the
  person sees and can Steer or delete. Mail is marked read when the chat
  accepts the turn, so check does not return it again; a deleted card leaves
  its mail unread for check, and it is not pushed again.
- The card stores who it is from (source_json): every distinct sender, and
  each message's id, run and sender. Kind 'mail-notice' becomes 'mail'.
- Removed: the send-time judge (QueuedAgentCardVerdict), structured-mail-
  notice, structured-pointer-notice-cards, queued-message-restatement, the
  hidden-card rules, the agent-card exemptions from the restart, Stop and
  /clear pauses, the dropped-card hand-back, and the drain split. An agent's
  card now follows the same pauses as a person's.
- Terminal agents are unchanged: they keep the typed pointer and check.

* fix(orchestration): a chat's check skips mail already queued to it; restarts hold only the person's cards

- When a structured chat runs `orchestration check` (consuming, --peek or
  --wait), mail an agent's card in that chat's own queue still carries
  (any card not deleted) is left out: it is on its way as a turn, so the
  agent does not read it twice. Derived from the queued rows at read time;
  a deleted card no longer carries it, so it comes back. Terminal callers
  and every other read are unchanged. New batches pass the exclusion to
  getOrCreateMailboxDelivery; peeks filter it.
- A restart's queue pause now holds only the person's cards: an unattended
  coordinator's agent card sends after an app restart without waiting for a
  Resume, since the mailbox is the record and reading is marked. Stop and
  /clear still hold agent cards. One rule, in queuePauseHolding. An agent
  card queued behind the person's held card still waits behind it: the
  queue never reorders.
- The duplicated direct-mailbox snapshot routing in check-run and
  check-worker becomes one helper, which keeps check-worker under its line
  limit.

* fix(orchestration): the mailbox is the only record of read mail; a chat's check takes its waiting cards

A card held an exclusive claim on its mail that nothing reconciled with the
mailbox: queueing it stamped the mail delivered, and a chat's check hid every
card that was not deleted. So a chat's own check --wait in one turn could not
see a result its waiting card held, a hand-off that ended in doubt or came back
"Not sent" stranded its mail, a check racing the card's build read the mail
twice, and a card left behind by run-use still sent and marked it read.

What a card or send holds is now derived each time from the chat's queue and
its sends: an accepted send marks its mail read; a waiting card or an
unanswered send holds its mail; everything else unread is pushed again or
returned by check. A card the person deleted is recorded as not to be pushed,
at the delete. The lane withdraws returned, partly read and moved cards. A
chat's consuming check withdraws the waiting cards holding what it reads, one
at a time with the lane. The sender is stored on the sent submission too
(host-only), so read state survives the card row's prune. A refusal before
anything started ends its operation; a restart pause is raised only by the
person's cards; an unreadable agent source stays an agent's.

* refactor(orchestration): a chat gets the pointer a terminal agent gets, sent through the chat's own queue

A structured chat now receives exactly what a terminal agent is typed: "You have N orchestration
messages ... run `orca orchestration check`" (formatMessagePointer, same CLI name). It goes
through the shared sendAgentTurn with delivery 'queue', the composer's queue-if-active: an idle
chat gets it at once, a busy chat's queue holds it as a normal card and sends it when the turn
ends. The lane's idle gate is gone; the send decides, as for the person's message.

The lane queues no second pointer while one of its cards still waits, read from the queued rows;
mail arriving meanwhile, or after the card is sent, is pointed again as the terminal lane points
new unread mail. A queued pointer counts as delivered, as an accepted one does. `check` and mail
read state are main's: only `check` reads mail.

The card records who it is from (queued_messages.source_json, kind 'agent', message
'mail-notice', with its senders) for the next PR to render. A restart's pause is raised by and
holds only the person's cards; Stop and /clear still hold an agent's.

Removed from the earlier designs: the message-as-turn batching, the check exclusion and taking,
the derived claims, lock and reconciliation, the sender on submissions, and their tests.

* fix(orchestration): a chat's pointer follows a card that leaves its queue unsent

The lane holds new mail while a pointer card waits, and retried it only on the chat's next
status change. A card that leaves the queue without a turn after it (the person deletes it
while Stop holds it, or its hand-off comes back) made none, so that mail sat unpointed until
something unrelated happened. The shared queue wiring now tells its host when an agent's card
stops waiting, read only when the queue changed, and the runtime redrives that chat's parked
mail. The runtime forwards the new host dep like the others.

Tests: that case end to end, and /clear carrying an agent card keeps who it is from. Agent card
bodies in tests are the pointer text; the restart pause's header says why an agent card may send.

* refactor(orchestration): no special handling for agent notices in the chat queue

A structured chat's orchestration notice is now sent through the chat's own send
like any message: an idle chat takes it as a turn, a busy chat's queue holds it
and sends it at turn end, under the same Stop, restart and /clear pauses as the
person's cards. Native chat no longer branches on who a card is from; the card
only records it.

- Restore main's queue pause logic (no restart exemption for agent cards).
- Remove the queue watch that redrove mail when an agent card left the queue,
  and the host's queued-row read the lane used for it.
- The lane reads nothing of the chat's queue. It sends no second notice while
  mail it already pointed at is unread, read off the mailbox alone.

* fix(orchestration): point new mail like a terminal, even while earlier pointed mail is unread

Drops the native-chat-only rule that held back a notice while the agent had not yet read mail it
was already pointed at. Also fixes main's stop-note test, which still built a provider handle in
the shape #24991 replaced.

* test(native-chat): keep the queued-message rig fixture under the line limit

* fix(test): drop main's duplicate codexProviderHandle import (same line as #25713)

Subject: [PATCH 063/167] chore(i18n): translate 76 new keys to es/fr/ja/ko/zh
 (#25719)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Delta since last scan (a15a5c8c1a6): 87 new en keys plus 18 changed en
values. 11 of the 87 are provider credit-balance keys that
provider-credit-balance-locales.test.ts intentionally keeps absent from
target catalogs (sparse English fallback), so they were left untranslated;
the remaining 76 were translated for all five locales. 15 of the 18
changed values already matched the new English upstream; 3 stale ones
(Gemini CLI legacy copy/label, onboarding arrow spacing) were corrected.

Applied via apply-translation-delta.mjs and the repairTranslatedValue
policy gate (ja open->オープン, zh 智能体->代理, ko spacing). Strictly
additive: +380 locale keys, 0 removed.

Three subagent review rounds (max 4): R1 fixed 11, R2 fixed 3 and
rejected the ja half-width-colon and ko pinned-override findings as repo
conventions, R3 signed off clean on all five locales.

Gates: catalog verify, coverage --check, extraction, runtime-catalog, and
the locale vitest suites (34 files / 288 tests) all pass.

+## Scan 2026-10-05

+- HEAD scanned: d3943c6d81 (origin/main; branch rebased onto it). Base: a15a5c8c1a6.
+  Window: a15a5c8c1a6 .. HEAD (~1008 commits). Note: origin/main was still advancing
+  during the scan; the one en key added in the last 13 commits (browser markup
+  `...tool.eraser`) already shipped translated upstream in all five locales.
+- Gates before fix: catalog verify PASS (all five locales missing the SAME 87 keys),
+  coverage --check PASS (13 allowlisted), extraction PASS, runtime-catalog PASS.
+  So no unkeyed strings and en.json in sync; the gap was target-locale coverage only.
+- Delta since base: 87 new en keys (csv editor x34, provider credit balance x11,
+  activity x31, jira assignee x3, workspace-delete change checks x5, nested-worktree
+  removal x10) plus 18 changed en values (Gemini CLI legacy, structured-chat copy/scope,
+  markdown notes, unverifiable -> "no recent update", onboarding casing, arrow spacing).
+  es had fully caught up to fr/ja/ko/zh, so all five shared the same 87-key gap.
+- **11 of the 87 are intentionally untranslated**: the provider credit-balance keys
+  (`auto.components.status.bar.{StatusBar.*,tooltip.*,provider.extra.usage.section.*}`)
+  are pinned as sparse-fallback by `provider-credit-balance-locales.test.ts` (#25408),
+  which asserts every target catalog OMITS them and falls back to English at runtime.
+  Translated the remaining 76 new keys (x5) and left the 11 balance keys absent.
+- Changed-value review: 15 of the 18 already matched the new English upstream; only 3
+  were stale (AccountsPane Gemini legacy description + label, onboarding arrow spacing).
+- Applied 76 new keys x5 via apply-translation-delta.mjs (pipeline repaired ja
+  open->オープン, zh 智能体->代理 xN, ko refreshFailed spacing) + 3 stale updates x5 via
+  the same repairTranslatedValue gate. Strictly additive: +380 new keys, 0 removed.
+- Gates after fix: catalog verify PASS (all five 15268/15279; the 11 omissions are the
+  pinned balance keys), coverage --check PASS (13 allowlisted), extraction PASS,
+  runtime-catalog PASS, locale vitest suites PASS (34 files, 288 tests).
+- Reviews (3 of max 4 rounds; round 0 = 5 parallel translators, then 5 reviewers/round):
+  R1 applied 11 fixes (es structuredCopy "Off"->"Si está desactivado", structuredScope
+  semicolon lowercase, 5f02e6fb21 review->"de revisión"; fr nestedRemoval pronoun

+  zh f80603d293 切换->交接/注释->笔记 + threadListOptionsActive->个生效).
+  R1 rejected 2 as repo-convention conflicts: ja TaskPage half-width 例: (28 existing
+  occurrences) and ko showMoreAgents (pinned Latin "agents" by
+  config/scripts/locale-ko-key-overrides.json, so no locale change).
+  R2 applied 3 (es structuredScope unified "chat de terminal"; zh structuredCopy
+  ->基于终端的 + activity hideAutomation/CLI-created re-add 工作区 to match ja/ko);

Subject: [PATCH 065/167] test(agent-launch): keep the carry control on a
 prompt that still cannot ride the line after #23672 (#25734)

#23672 quotes a multi-line PowerShell argument as one physical line, so the control's short
multi-line prompt now rides the line on a Windows host that can prove the agent, and the unit shard
went red. The control now uses a multi-line prompt over the typed budget, which still pastes, and a
new test pins that a short multi-line prompt rides the PowerShell line as one physical line.

Subject: [PATCH 066/167] fix(feedback): optimize oversized screenshots without
 losing detail (#23664)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* fix(feedback): shrink oversized screenshots instead of refusing them

Fixes #22776

* fix(feedback): release each shrink canvas and skip the PNG ladder for a JPEG

Two defects in the attach-time shrink ladder:

- Every step allocated a fresh full-size canvas and left it for the garbage
  collector, so a 32-megapixel source could keep six of them alive at once.
  Past the renderer's canvas memory budget Chromium hands back a blank canvas,
  which would upload as a blank screenshot with nothing to notice it. Each
  step's canvas is now released once toBlob has answered.
- A JPEG source ran two full-size PNG encodes first. A PNG of decoded JPEG
  noise is many times larger than the source it has to undercut, so those
  steps could only ever burn time and a large buffer before the first JPEG
  attempt. A lossy source now starts at the JPEG steps.

* fix(feedback): keep the image read queue usable after a settle callback throws

The queue tail is what the next batch awaits. A throw in either settle callback
left it rejected, so every later attach short-circuited into "Could not read the
attached images" without reading anything — and the rejection went unhandled.

* feat(feedback): say when an attachment is still being prepared

Shrinking a full-screen capture takes long enough that the gap between picking
the file and its thumbnail appearing reads as a dropped attachment: the only
other signal was the Send button quietly staying disabled. The attachment hint
now reads "Preparing attachments…" while a batch is in flight.

* fix(feedback): report an undecodable oversized image as invalid, not too large

* fix(feedback): detect an animated PNG by walking its chunks, not a 64 KB text scan

* docs(feedback): stop claiming toBlob encodes off the renderer thread

* refactor(feedback): seed the image read queue ref directly

* test(feedback): cover the real decode, downscale and release path of the shrink

* perf(feedback): skip image batches still queued when the dialog unmounts

* fix(feedback): show the preparing hint only once a read outlasts a short delay

* test(feedback): pin the animated-PNG walk on corrupt lengths and a refused image's budget

* fix(feedback): blame the shared budget, not the file size, when a shrinkable image has no room

* fix(feedback): cap each shrunk screenshot at half the attachment budget

A shrink kept the largest step that fit everything left, so the first
full-screen screenshot took a 3.8 MB PNG, the second fell to a barely
readable JPEG and the third was refused. Re-encodes now target at most
2 MB; an image that already fits is still attached untouched. The
"larger than 4.0 MB" refusal now applies whenever the capped target an
empty budget would give was the one that refused it.

* test(feedback): pin the half-budget shrink cap independently of its constant

* fix(feedback): reserve a shrinking screenshot's capped size, not its file size, for the paste gate

A 6 MB screenshot still shrinking reserved 6 MB, more than the whole budget,
so a second paste during the shrink fell through to the textarea even though
it attached. Each pending file now reserves what the reader can commit under
the same fit and shrink-target rules. Also corrects the minimum shrink target
comment to the measured smallest step.

* docs(feedback): correct the canvas-release and shrink-queue test comments; mock toast.info in the dialog test

* Revert "refactor(feedback): seed the image read queue ref directly"

This reverts commit e2272b825eb2d26286aee3a99ca28f3ea984508e.

* fix(feedback): keep preparing hint compatible with current main

* fix(feedback): preserve mixed paste text and seed read queue on attach

* fix(feedback): preserve screenshot detail and pending paste text

Optimize oversized attachments only as full-resolution lossless PNG; refuse them with existing warnings when that cannot fit. Bound each pending batch independently so earlier optimization slack, rejected files, or removed drafts cannot under-reserve bytes and swallow co-pasted text. Regression tests demonstrate the old mixed-batch text loss.

* test(journal): retain provider handle import across main integration

* test(startup): account for encoded Windows prompt lines

* test(compatibility): retain the released journal parser dependency

Subject: [PATCH 067/167] fix(native-chat): show the message rail from the
 first user message (#25707)

* fix(native-chat): show the message rail from the first user message

The rail on the right of native chat stayed hidden until a conversation had
three user messages, so short chats had no rail at all. Show it whenever there
is at least one user message (still hidden in panes too narrow for it).

Co-Authored-By: Claude <noreply@anthropic.com>

* fix(test): remove duplicate journal fixture handle import

+## October 5 localization gate work
+
+The localization coverage audit now classifies only AST nodes that can emit string
+parts, and reuses the class-property exclusion set. It still visits every child and
+handles JSX text separately. The extraction scope skips only source extensions and
+test paths explicitly excluded by the real extractor configuration. Catalogs,
+assets, unknown extensions, configuration changes and mixed production changes
+still select extraction; both sides of a rename remain covered.
+
+The [hosted comparison](https://github.com/stablyai/orca/actions/runs/37360932616)
+used fixed source `761d63a4e52ff7915d4432c004df13182db63010`, Linux ARM,
+Node 24.21.0 and pnpm 12.8.1. Dependency setup was shared outside the samples.
+Each timed check was a fresh process with Node compile caching disabled.
+
+| Complete coverage audit | Original | Candidate | Paired saving |
+| ----------------------- | -------- | --------- | ------------- |
+| Pair 1                  | 9.182s   | 4.924s    | 4.258s        |
+| Pair 2, reversed order  | 9.133s   | 4.924s    | 4.209s        |

+
+The median paired saving is 4.209 seconds, or
+46.1% of this audit. All three pairs improved; the original range was
+0.252 seconds. Complete JSON finding inventories match byte-for-byte,
+including all 13 findings and their source locations. All 53 candidate tests pass.
+Four real audit mutations fail their intended assertions. An ignored test fixture
+passes the real extraction gate; renaming it into production source selects the
+gate and fails on the deliberately missing translation key.
+
+For an existing ignored test path, three conditional comparisons avoid a median
+27.628 seconds of extraction work. Original arms really run the full gate
+and pass; candidate extraction arms are explicitly `not_selected`. The routing
+tests pin the actual extractor inputs and exclusions, so configuration drift fails
+the tests. This saving applies only when every changed source path is ignored.
+
+Relay integration also omits desktop native preparation and the Electron archive
+cache. Its existing two files use Node's SQLite, HTTP and WebSocket paths; general
+unit shards retain their desktop setup. The existing 16 relay cases pass locally
+on Node 24.20.0 and 26.7.0. Removed setup work is not a measured timing saving.
+
+These comparisons exclude queues and other checks. Extraction already overlaps
+other preflight work, so conditional avoidance does not translate directly into
+preflight wall time. No change to full-PR percentiles or the concurrency allowance
+is established.

Subject: [PATCH 069/167] fix(claude-accounts): preserve shared MCP OAuth
 credentials across an account switch (#21931)

* fix(claude-accounts): preserve shared MCP OAuth credentials across an account switch

Orca's account switch writes the target managed account's own stored credential
verbatim to the global "Claude Code-credentials" Keychain item. That credential
never carries mcpOAuth/mcpOAuthClientConfig/mcpXaaIdp/mcpXaaIdpConfig/pluginSecrets
(they are machine-shared MCP connector state, not per-account), so every switch
silently drops any MCP connections the previous session had.

Merge the live credential's copy of these shared fields into the target credential
right before the Keychain write, live-wins (absence included), mirroring how the
third-party claude-swap tool already treats this exact shared Keychain item.

Fixes #16098

* fix(claude-accounts): skip reformatting shared credential merge when nothing changed

mergeSharedClaudeCredentialFields always re-serialized via JSON.stringify, even when
the shared-key set was identical on both sides. The reformatted-but-semantically-equal
JSON (e.g. missing the original trailing newline) then read as an external Claude Code
refresh to the read-back byte-equality check in runtime-auth-sync, causing every
subsequent sync to wrongly adopt it into managed credential storage.

Return the original string when the merge changes nothing.

* fix(claude-accounts): validate OAuth shape, preserve key order, and degrade Keychain read failures

Address CodeRabbit/pullfrog follow-up review on the shared-credential merge:

- parseCredentialObject accepted claudeAiOauth as null or a primitive; the merge would
  then serialize the malformed target instead of passing it through unchanged. Validate
  it is a non-null object (hasClaudeOauthObject) before merging.
- The no-op guard compared whole-object JSON.stringify output, so an existing shared key
  interleaved among target-only keys got moved to the end of the rebuilt object even when
  its value did not change, producing a formatting-only rewrite. Compare per shared key
  and keep the target's own key order via object spread instead.
- runtime-auth-sync read the live Keychain credential for the merge with the raw
  (non-best-effort) function, so a transient Keychain read error aborted the whole
  account switch instead of just skipping the merge. Use the inherited
  readAggregateClaudeKeychainCredentialsBestEffort, matching every other Keychain read
  in this subsystem.
- Fixed a dead citation URL (scaryghost/claude-swap 404s; the real repo is
  realiti4/claude-swap, verified to contain the cited SHARED_CREDENTIAL_KEYS /
  merge_shared_credential_fields).
- Added docstrings to every function touched by this change.

Tests: 5 new cases (null/primitive claudeAiOauth, interleaved shared key no-op and
update, Keychain read failure does not abort the switch).

* fix(claude-accounts): preserve connector state across all runtime credential writes

Keep live MCP grants in both runtime files and keychain items, excluding shared secrets from managed account capture and refresh read-back. Preserve rotations and revocations through default restoration and reject unreadable live state before destructive writes.

* fix(claude-accounts): retain grants from all live stores on startup

Before Orca has a last-written baseline, a missing shared field in one store cannot prove revocation. Carry present fields from the other live stores, prioritizing a proved newer refresh candidate when available.

* fix(claude-accounts): reconcile connector updates without guessing token freshness

* test(preflight): freeze clock for Windows PATH probe assertion

Subject: [PATCH 070/167] feat(pi): show Pi and OMP background children as rows
 (#23201)

* feat(pi): show Pi and OMP background children as rows

Refs #22868

* fix(pi): derive the extension's roster cap from the host's

The generated extension re-typed the 32-row limit as its own literal, so
a change to AGENT_STATUS_MAX_SUBAGENTS would leave the extension posting
rosters the host silently truncates on arrival. Interpolate the host
constant instead, and cover the cap with a test that posts past it.

* test(pi): pin the Pi cancel verdict beside a live child row

Publishing a subagent roster for Pi puts its panes behind the same
child-work guard Claude and Codex sit behind, so Ctrl+C beside a live
child no longer settles a stopped row. The extension reports no
main-agent state, so Orca cannot tell a cancelled turn from Ctrl+C at
the idle prompt of a lead children alone hold open, and keeps the live
row. Both halves of that are now pinned, as is the resume-placeholder
guard on the model_select arm of the same code path.

* fix(pi): end a run with its session and keep children across reload

Pi re-runs the extension on a fresh event bus for /new, resume, fork and
/reload, so the roster kept on that bus was lost and nothing ended the
run the old session's children held open.

* fix(pi): preserve pending completion and OMP pane ownership

* test(pi): use the hook owner context type

* fix(pi): retain completion timers and delivery across session boundaries

* test(omp): preserve unsent completion at session boundaries

* test(journal): retain provider handle import across main integration

* test(startup): account for encoded Windows prompt lines

* fix(pi): serialize status delivery across module reloads

* test(compatibility): retain the released journal parser dependency

Subject: [PATCH 071/167] feat(files): reveal Source Control files and terminal
 file links in the file manager (#24502)

* feat(reveal): reveal changed files and terminal file links

Reveal only existed on file explorer rows. Every reveal menu now shares
one action, so a missing file or a remote workspace behaves the same
in all of them.

Fixes #24003

* fix(reveal): address review findings on missing links and SSH files

A hovered hyperlink to a missing file saved "missing" in the cache plain
path links trust, hiding the path once the file existed. A tab holding an
SSH file from outside its workspace still offered reveal.

* fix(reveal): drop reveal from check-details tabs

Their path is a synthetic id, so reveal could only fail.

* fix(reveal): use scoped file access for directory checks

* fix(reveal): retire superseded Spanish menu labels

* test: preserve explicit file access and untranslated-locale contracts

* refactor(terminal): reveal a file link from its click popover, not the right-click menu

The terminal "Reveal in Finder" action now lives in the file-link popover
(the one with "Open file" and "Open with default app"), as a row with no
click shortcut. It goes through the shared reveal, so a folder link (including
a macOS .app or .xcodeproj bundle) is selected in its parent and never opened.

The row is omitted, not disabled, when the file is not on this machine: an
SSH or runtime-owned file, a pane whose shell runs on another host, or while a
remote runtime is focused. Workspace-root links keep their own "Open in
Finder"/"Open folder" row and get no reveal row.

Removes the right-click path: the context-menu item, the hovered-link tracking
and its OSC 8 / path-existence probe refactors, the directory stat (and its
user-named file-access grant, which only served the open-a-folder behaviour),
and the right-click e2e case. Terminal files the PR touched are back to main
apart from the popover row.

Co-authored-by: Kelvin Amoaba <97001695+AmoabaKelvin@users.noreply.github.com>

* test(terminal): type the reveal settings fixture without assertion

* test(startup): account for encoded Windows prompt lines

* test(compatibility): retain the released journal parser dependency

* test(journal): retain one canonical provider-handle import

* fix(terminal): give the popover's Reveal in Finder row the reveal icon

Every other Reveal in Finder item shows the external-link icon; the link
popover draws it for rows that open outside Orca, so mark the row that way.

Subject: [PATCH 072/167] fix(agent-status): retire a removed worktree's
 hook-status rows (#23881)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* fix(agent-status): retire a removed worktree's hook-status rows

Rows whose terminal was never reattached had no teardown path, so they
outlived the worktree in last-status.json for up to 7 days.

Fixes #23068

* fix(agent-status): skip panes another owner has since reclaimed

* fix(agent-status): clear only the removed owner's claims on a shared pane

* fix(agent-status): retire hook-status rows a host scan proved removed

`worktrees:forgetRemovedForExecutionHost` is the only path that ever retires an
off-host WorktreeMeta row: gcStaleWorktreeMeta skips any row whose repo or
hostId is not local. It already prunes the cleanup and space-analysis snapshots
for a worktree a remote scan proved gone, but left that worktree's hook-status
rows behind in `last-status.json` — the same stranding this branch fixes for the
in-Orca delete, reached through the other trigger.

A scan the host answered is positive evidence of removal rather than loss of
contact, so it is the host evidence `ssh-execution-boundary.md` requires, and it
publishes no verdict. The drop is scoped to the scanned host's id, so a same-id
worktree on another connection keeps its rows, and a runtime host falls through
the method's own early return because a paired server owns its own store.

Also names the shared-pane condition in `dropStatusEntriesForRemovedWorktree`,
which was the one place the two-owner logic was hard to read.

* fix(agent-status): stop a removed worktree's row returning on a shared pane

The mixed-owner branch deleted the removed worktree's row but left the pane
unfenced, so the stale row came straight back. `getAgentStatusDisposition`
returns `accept` for an unfenced pane, and the removed worktree's agent can
still post a late turn on a pane it shares with another owner — I reproduced the
`working` row being rewritten to memory and to `last-status.json`, which is the
symptom #23068 is about.

A launch-token fence cannot close this: `ingestTerminalStatus` calls the
disposition gate with no event, so the token check never runs and an OSC report
carries no token to check. The pane fence the sole-owner path already uses does
suppress it, and it lifts on PTY reattach or a new agent's turn.

Fencing the pane would otherwise discard the surviving owner's claims, which is
what the branch existed to protect, so both of its records are captured first
and restored after: its persisted authority commitment (its resume identity) and
its current authority observation. The observation also fixes a second defect on
this path — `deleteStatusEntry` drops it whatever `preserveAuthority` says, so
the surviving owner silently lost `current_runtime` attestation until its next
hook event.

Both are covered by tests that fail against the previous commit.

* fix(agent-status): decide a reused pane by its occupant, and retire rows for local scan-proved removals

A pane has one terminal, so its newest row names who occupies it. A saved
commitment naming a different owner is what an earlier occupant left behind,
and serialization already drops it while the row disagrees. Removal now retires
a pane the removed worktree occupies, and on a pane another owner occupies it
clears only the removed worktree's outlived commitment. This replaces the
capture-and-restore handling of two-owner panes.

The local authoritative-scan prune is the local twin of the SSH scan forget: it
drops a worktree's metadata once the scan proves it gone, and now retires its
status rows too.

* fix(agent-status): preserve foreign authority during worktree removal

* fix(agent-status): preserve terminal connection validation

* fix(agent-status): keep ordinary OSC admission unchanged

* refactor(agent-status): colocate the remote envelope type

* fix(agent-status): revoke removed startup authority evidence

* fix(agent-status): retain foreign startup claims during removal

Subject: [PATCH 073/167] fix(relay): deploy driver builds the checked commit,
 prompts on their own line, summarises progress (#25755)

* fix(relay): publish the reviewed commit before main can move, and quiet the deploy driver

The publish workflow builds main's head at dispatch. The driver checked main
at preflight but dispatched the publish about four minutes later, after the
inspects and the typed phrase, so a busy main stopped the first real deploy.
It now dispatches the publish seconds after the check, before anything else,
and a build of a moved main stops with the --commit/--publish-run command that
deploys it once reviewed. Typed prompts end in a newline, and runs are
summarised (status changes plus every 5 min) instead of streaming gh run watch.

* fix(relay): a main-moved stop prints only the command that reuses the build

The generic re-run line named the reviewed commit without --publish-run, which
would only build the moved main again.

Subject: [PATCH 074/167] feat(relay): give Asia cell c34 a promotion wave so
 it can become a general cell (#25757)

* feat(relay): give Asia cell c34 a promotion wave so it can become a general cell

c34 launched on 2026-10-05 as a migration-only spare with no promotion path. This adds
it to the Asia admission promotion waves, the workflow's promote and canary cases, and
the canary evidence map, so the reviewed Asia workflow can promote it with the same
five-minute canary c30 and c31 ran.

The same-cap migration-only list is deliberately unchanged: a same-cap job reads a
cell's class from that list, and c34 must be rolled to the director's image as a
migration-only cell before promotion can run. The list moves after promotion, in its
own change.

Claude-Session: 1145a80d-dec4-4a9b-9373-bbbb876b9041

* docs(relay): scope the c34 same-cap pause to the window after promotion

Claude-Session: 1145a80d-dec4-4a9b-9373-bbbb876b9041

* docs(relay): rewrap the c34 paragraph

+was its own topology wave, registered alone as migration-only, and the director was configured with
+`cell-ids` set to C34, all on 2026-10-05. It launched as a migration-only spare and now has a

+C34 because it is the emptiest general Asia cell once promoted. Promotion compares the director's

+rolled to the director's image. That roll is a same-cap wave that enters and leaves

+succeeds, because a same-cap job reads a cell's class from that list, not from the selector. It
+then moves to the general list and the fleet pool list together, as its own reviewed change,

Subject: [PATCH 075/167] fix(dock): clear stale workspace unread counts
 (#24877)

* fix(dock): count only the unread the app shows

Tab markers outlive the workspace unread flag, so the badge could
sit at 1 with no sidebar dot to find or clear.

Fixes #23363

* fix(dock): follow the sidebar's host filter in the unread count

Counting folder workspaces and per-host rows by flag put rows on the
Dock that a host-scoped sidebar does not show.

* fix(dock): preserve owned folder alerts without expanding unread counts

* fix(dock): honor the existing other-device worktree filter

Subject: [PATCH 076/167] =?UTF-8?q?chore(i18n):=20use=20=E6=99=BA=E8=83=BD?=
 =?UTF-8?q?=E4=BD=93=20for=20Chinese=20Agent=20copy=20(#25767)?=
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Simplified Chinese rendered the Agent concept as 代理, which collides with
代理 = proxy. Standardize on 智能体 for Agent (and 子智能体 for subagent),
while keeping 代理 for proxy senses: HTTP/network proxy, SSH Proxy Command,
reverse proxy, and browser user agent.

- Converted 131 zh catalog values (incl. 子代理 -> 子智能体); 26 proxy /
  user-agent values left as 代理.
- locale-phrase-fixes.mjs: 客服人员/代理商/座席 -> 智能体, 代理 -> 智能体 when
  the English names an agent (guard excludes "user agent"); removed the old
  智能体 -> 代理 rule so the pipeline no longer reverts it.
- Updated value/key/search/macos-tcc overrides to 智能体; proxy keyword and
  proxy override entries unchanged.
- Updated the two policy tests that pinned the old 代理 output.

Gates: catalog verify, coverage --check, extraction, runtime-catalog, and
the locale vitest suites (296 tests) pass.

+## Terminology change 2026-10-06 — zh Agent is 智能体, not 代理
+
+- Standardized Simplified Chinese on 智能体 for the Agent concept. Converted 131 zh values
+  (incl. 子代理 -> 子智能体) and updated the pipeline so it is not reverted:
+  `locale-phrase-fixes.mjs` now maps 客服人员/代理商/座席 -> 智能体 and replaces 代理 -> 智能体
+  when the English names an agent (guarded to exclude "user agent"); the old
+  智能体 -> 代理 rule was removed.
+- 代理 stays for proxy senses: HTTP/network proxy, SSH Proxy Command, reverse proxy, and
+  browser "user agent" (26 zh values left untouched). Overrides updated to match
+  (locale-value-overrides, locale-key-overrides, locale-macos-tcc-key-overrides,
+  locale-zh-value-overrides, locale-search-keyword-overrides agent/agents -> 智能体, proxy -> 代理).
+- Gates: catalog verify, coverage --check, extraction, runtime-catalog pass; 296 locale
+  tests pass (policy, zh-round5, generic-terms, etc.).

Subject: [PATCH 078/167] Stage long agent launch lines where they are typed,
 so they arrive whole (step 2 of 7) (#23962)

* feat(agent-launch): host-side prompt delivery for agent.launch

The host's agent.launch typed any launch prompt into the shell as part of the
launch command. A long or multi-line prompt then ran line by line in the
shell, and an agent that never showed readiness or crashed at startup had
nothing guarding where its text went.

agent.launch now carries a prompt on the typed line only when the line stays
one line, control-free and at most 512 bytes; otherwise the agent starts
clean and the host pastes the prompt once the agent's own ready signal fires
(bracketed paste plus its composer marker or a quiet render, read only after
the shell's last hand-off, never while the pane's own shell is proven in
front), with main's draft-paste bytes and an Enter 50 ms later. Orchestration
worker starts wait on tui-idle as before. A replay-safe launch admits and
claims its ledger row in one write, Qwen Code gets a second Enter, the
desktop and phone share one launch-refusal classifier, and hosts advertise
agent.launch.prompt-carry.v1.

Split out of #23748, which moves the desktop source-control buttons onto
this path.

* fix(agent-launch): keep a short-lined multi-line prompt on a local zsh launch line, as main did

#24257 moved every multi-line or over-512-byte prompt off the typed launch line and pasted it after readiness. The phone's AI buttons and review notes, whose multi-line prompts main typed whole into zsh, then reached Claude 0.5-3 s later and their RPC reply waited for the paste.

The host now names the shell a local macOS or Linux line is typed into, the way the spawn picks it, and a multi-line prompt rides a zsh line when every line is at most 512 bytes and the whole line at most 8 KB. A real-zsh test types such a line through Orca's own ready barrier and startup write, including when a slow user config makes the write land early. Elsewhere the measured unsafe cases keep the paste: bash 3.2 runs multi-line lines piecemeal, fish drops an early multi-line write, and any shell loses a line over 1 KB written early.

* test(agent-launch): keep the real-zsh launch-line test out of the Windows lane's gate scan

The Windows lane registration check read `const ZSH_PATH = process.platform === 'win32'` (the head of a multi-line ternary) as a Windows-true flag, so `describe.skipIf(!ZSH_PATH)` looked like a Windows-only suite. The file is POSIX-only; the zsh lookup is now a function.

* refactor(protocol): move the agent.launch capabilities into their own module

Main's protocol-version.ts sits at the 300-line cap, so the prompt-carry capability pushed it over. The four agent.launch capabilities and their doc move to agent-launch-runtime-capability.ts, re-exported by name and spread into RUNTIME_CAPABILITIES at the same position; the advertised lists and every export are unchanged.

* refactor(protocol): import the agent.launch capabilities from their own module

`export *` from protocol-version left the four names undefined under the mobile recording loader, which resolves a relative import through a Proxy with no own keys, so 37 phone recordings lost agent.launchReplay. Importers now name agent-launch-runtime-capability directly; protocol-version only spreads its list.

* refactor(agent-launch): drop the unshipped viewMode field and trusted local caller id

Both were inert in step 1 and existed only for step 2. agent.launch will become a
public plugin API, so every wire field is permanent once shipped; a top-level
viewMode reads as "choose terminal vs chat", which the host decides. Step 2
introduces placement and view intent under a placement object instead.

* fix(agent-launch): read Codex's provisional startup from the rule files' hold anchor

Main (#24375) moved Codex's provisional-header check into codex.json's
provisional_startup hold anchor and deleted codex-terminal-readiness.ts, so the
launch readiness hold now asks showsHoldAnchor, as main's own settled check does.

* fix(agent-launch): hold rule-file name titles to quiet for a launch, and census the zsh fixture

Main (#24375) answers a name-only title from each agent's rule file ahead of the
sustained-title lane, so gemini.json's name_title settled a launch readiness wait
on the shell's auto-title while Gemini was still booting. A launch now asks quiet
of every weak idle verdict, as that lane did.

Main's readiness census requires a recorder for every runtime fixture; the zsh
prompt recording is a non-agent control. Gemini's synthetic baseline is
regenerated for this PR's stated change: a bare gemini title is no longer its
rest mark, so name-only rows settle weak, and a fresh working or blocked status
is no longer overridden.

* fix(launch): stage long or multi-line launch lines so they arrive whole

A launch line that is long or has several lines could lose lines or wedge a
shell that is still starting, because it was typed into the terminal before
the shell could read it whole. The terminal host (local daemon, and the SSH
relay) now writes such a line to a script file and types one short line that
runs it, for every POSIX shell; a shell that cannot read Orca's quoting runs
Orca's own agent lines through /bin/sh. If the script cannot be written, the
terminal says so.

The SSH background launch path no longer types the line from the renderer;
the relay stages it like any other terminal.

Bumps the terminal daemon protocol to 40 (main took 39); a v39 daemon keeps
its sessions and gets no staged line.

Restacked onto #24257 from the version reviewed on top of #23748; carries
none of #23748's changes.

* fix(launch): run a staged launch line as its own job in fish and ksh

fish and ksh run the commands of a sourced file in the shell's own process
group, so a staged agent was not a job: Ctrl-Z was dropped (a typed line
stops), and the shell-in-front check saw the shell's group in the foreground
while the agent ran. fish now runs the script with
`eval (string collect < '<path>')`, which runs it as if typed and leaves the
shell's job-control mode alone. ksh and mksh run a long Orca-built line through
`/bin/sh '<path>'`, a real job; a long command the user wrote is typed as
before. The real-shell test now asserts the agent's process group is its own
and is the terminal's foreground group.

The staging rule also reuses hasControlByte and the 512-byte budget from
startup-line-prompt-carry so the carry and staging limits cannot drift.

* fix(agent-launch): paste a launch prompt only when the launched agent is proven in front

A launch pasted its prompt unless a shell was proven in the terminal's
foreground, so any read that could not prove one let the prompt through. After
an agent exited at startup, its shell turned bracketed paste on at the next
prompt, readiness fired on it, and the prompt was typed into the shell:

- macOS: a pane runs its shell under login, so the process-group fence's root
  was never the shell's group and never proved it; the cached foreground name
  could also still name the exited process.
- Windows Git Bash and WSL: the shell-alone-in-its-job check never answers.

Now one fresh read of the terminal's foreground decides: agent, shell or
unknown. Only 'agent' lets a write through (paste, Enter, second Enter, reused
panes too); 'shell' still drops a ready signal. A Windows host never proves the
agent, so there the launch line carries the prompt at any size, as on main.

* test(agent-launch): cover the Windows QA stub, a grok override that exits at once

* fix(agent-launch): keep the local socket alive while a prompted launch waits for its agent

A launch with a prompt now waits up to 60 s for the terminal agent to be
ready before it writes the prompt, and reports not-delivered when the agent
never is. The local runtime socket closes a connection idle for 30 s unless
the request is a long poll, so a launch whose agent exited at startup lost its
reply and the caller saw 'runtime closed the connection' instead of
not-delivered. Classify a prompted agent.launch and agent.launchReplay as a
long poll, as orchestration.workerStart already is for the same wait.

* refactor(agent-launch): narrow the launch params by 'in' instead of a cast

* fix(agent-launch): find a launched agent behind a wrapper that leads its process group

A tcsh or nu launch line runs the agent from /bin/sh '<script>', and a
wrapper script that does not exec its agent does the same: the wrapper leads
the terminal's foreground process group and the agent is a member of it. The
fresh foreground read names the group's leader, sh, so a prompted launch was
refused or pasted late (M4Air tcsh: 2 of 4 not delivered, 2 pasted ~9 s late).

Before that read, take the host's process-group observation as positive proof
when it names the launched agent among the foreground group's members and is
younger than a ready signal's quiet window. It never proves a shell.

* fix(launch): type a plain Orca agent line as is in tcsh and nu

In tcsh and nu, every Orca-built agent line ran through `/bin/sh '<script>'`,
so the agent was a child of sh in sh's process group. When the prompt was
pasted after the agent was ready, the paste guard read sh in front and, on a
loaded Mac, reported the prompt not delivered (4/4 live runs in tcsh).

Now only a line that needs it goes through `/bin/sh`: one over 512 bytes, with
a control byte, or with a character those shells would not read literally
(`!`, backslash, `"`, `$`, backtick). A plain line such as
`claude '--dangerously-skip-permissions'` is typed as on main, so the agent is
the shell's own job.

* fix(agent-launch): judge the foreground-group proof by when its capture began, not how long ps took

The age the host stamps on a process-group observation runs from the start
of its whole-machine ps, so on a loaded Mac a capture begun after the read
was asked for still read as older than 1 s and the proof was dropped. Count
an observation whose capture began after the read was asked for, less the
window a shared capture is reused across.

* test(agent-launch): keep the crash-guard live test out of the Windows lane's gate scan

The Windows-lane registration scan read the const assigned from a platform
check as a Windows-only gate, though the suite runs everywhere but Windows;
find zsh in a function instead, as the real-zsh typed-line test does.

Under load the fresh foreground scan can fail to answer, which lets the
shell's prompt settle readiness (2 of 4 paired runs). The guard still refuses
that write, so assert the refused write, the property that must always hold.

* perf(agent-launch): read a local pane's foreground from its own terminal, not the whole process table

The foreground read that gates every launch paste ran the daemon's
inspectProcess capture and then a fresh scan, each a whole-machine ps; the
fresh one also waits for any capture already running before it starts its own.
Measured here at load 5: 1.2 s a read (M4Air QA: 3.4-5.0 s, and worker starts
17.6-32 s against main's 9-12 s at load 25-84).

On a local macOS or Linux host, take the pane's root pid from the provider's
session inventory and run one ps limited to that pane's terminal. Its
foreground process group decides: the launched agent or any non-shell member
is the agent (a wrapper that did not exec its agent leads the group), a group
of shells alone is the shell. Same pane, same verdict: 2.7 ms a read. SSH hosts
keep the relay's observation and name.

* test(mobile): re-measure the web app's script sweep after agent.launch's capabilities moved out of protocol-version

The mobile web bundle check failed at 124 assets against a ceiling of 123. Main already sat
exactly on that ceiling: its sweep table read 69 scripts at 16 routes while the tree builds 73,
the whole margin of 4. This branch imports the agent.launch capabilities from their own module,
so protocol-version is no longer pulled into the root layout and four other routes. That moves
which routes share which modules, and the Qoder capability module, imported by protocol-version
and the AI-vault resume path, no longer shares an importer set with anything, so it gets a chunk
of its own: 74 scripts.

The fence says to re-derive the bound rather than raise it, so the sweep is re-measured on this
head (every prefix of the sorted route list). The worst route now adds 10 scripts (session), not
9, which moves the pinned shell crossing from 32 to 30 routes; main re-measured on its own lands
on the same crossing.

* fix(agent-launch): a worker's brief needs its agent found in front, and Grok's start answers on its composer

A paired-server worker start whose agent exited at startup typed its brief into the server's
shell, which ran it: the idle wait can settle on a shell back at its prompt, and the brief was
written with no foreground read. Both worker-start paths now check before each brief write, as a
launch prompt is checked: on a host that can find the agent in front it must be there; on one that
cannot (Windows) a shell proven in front still refuses, and anything else writes as before.

A Grok worker start waited ~10 s more than main: its only rest signal is its bare name, which a
launch holds to quiet output, and Grok animates its logo for ten seconds after its composer glyph.
A worker start for an agent whose rest signal is its bare name and whose composer draws a marker
(Grok, DSH, mimo-code) now also answers on that marker, whichever comes first.

* test(startup-staging): expect the CR that submits a typed launch line since #23672

Subject: [PATCH 079/167] fix(claude): API-key Claude users are told they're
 not signed in (#25163)

* fix(claude): open native chat for API-key users instead of saying "not signed in"

Claude reports tokenSource "none" beside apiKeySource "ANTHROPIC_API_KEY" when it runs on
an API key (environment or settings env). The startup check read only tokenSource, so it
refused those chats as signed out. Refuse only when Claude reports no token source and no
API-key source.

Co-Authored-By: Claude <noreply@anthropic.com>

* test(claude): cover a Console /login key at chat start

Subject: [PATCH 080/167] refactor(native-chat): structured agents declare
 their capabilities instead of shared code naming Claude and Codex (#25076)

* refactor(native-chat): keep the provider resume handle opaque to shared code

Shared structured-chat code parsed each provider's resume handle: Claude's
session id and branch leaf, Codex's thread id, through a 'claude' | 'codex'
union every new agent had to widen. The in-memory handle is now
{ transport, agent, nativeId, providerData? }: shared readers use nativeId,
lease and handle-chain checks compare transport and agent, and only the
Claude adapter reads its leaf (providerData).

Stored and wire forms are unchanged for Claude and Codex. One encoding
module writes their typed shapes and decodes both those and the neutral
shape a new transport uses, which an older build refuses as unreadable
rather than reading as Codex. Key and root strings, which fork seeds,
superseded creations and resume offers persist, stay byte-identical.

The journal's own handle type becomes the journal-row and attach-wire
encoding of the same handle, and the journal identity carries the
neutral handle (null before the provider proves one).

No user-visible change.

* fix(native-chat): derive journal-row provider handles from the journal identity

The journal row converter now takes the identity every caller already holds,
so a row's handle has one obvious constructor. Tests that wrote the in-memory
handle straight into journal rows now build it through that converter, and the
processless Claude fixture names a not-yet-proved handle as null.

* fix(native-chat): refuse a stored provider handle written in both forms

A typed Claude or Codex handle that also carries the neutral form's
transport, agent, native id or provider data named two identities; it
was read as Claude or Codex and the next write dropped the other one.
Such a row now stays unreadable and is set aside untouched.

* refactor(native-chat): route structured agents through registered definitions

The structured-chat shared layer named Claude and Codex in a closed router
type, in option reads, in frame classification, and in renderer label and
validation branches, so adding an agent meant editing shared types. Each
agent now has a definition (capabilities, resting option rules) owned by its
own module; the router is a registry of definition + adapter pairs built at
runtime setup, and shared code reads the definition instead of the name.

No behavior change for Claude or Codex; no wire or stored shape change.

* refactor(native-chat): name the structured agent list once in host types

The host types, conversation commands, provider-session ownership and the
runtime's create path spelled the structured agent list inline; they now use
the one shared type the record and wire already validate against.

* fix(native-chat): narrow the record before reading its agent's option rules

* refactor(native-chat): make the router's registrations the only agent definition lookup

The at-rest option reads looked definitions up in a second, separately populated map, so a
registered definition could route and declare capabilities while the static map decided which
options a chat at rest accepted. The router now answers `definition(agent)` from its
registrations, the at-rest readers take it through the host's adapter, and the built-in
definitions are listed only where the runtime composes the router.

* test(native-chat): use opaque handle in queued rejection fixture

* test(native-chat): share one Codex journal identity in the integration suite

Main grew the suite to the 800-line limit; the opaque-handle import pushed it
over. The two tests built the same identity inline.

* refactor(agent-session): name the handle's adapter state resumeCursor

Rename the neutral provider handle's providerData to resumeCursor before any
row persists the neutral form: it is an adapter-owned resume position (Claude's
transcript leaf), never identity. Claude/Codex stored and wire bytes are
unchanged; their typed shapes never carried the field.

State the stored-form contract (a handle's field set is closed; later per-link
data goes on the chain link, which every build preserves) and pin it with a
record round-trip test. Document that transport records the id space the
native id was minted in, which can differ from the agent's current transport.

* refactor(agent-session): one required agent registry; declarations admit what they claim

A StructuredAgentRegistry, built once from the {definition, adapter}
registrations, is now a required host dependency and the router routes with
it. The adapter interface loses its optional router-only capabilities?() and
definition?(); every reader (options at rest, thread goal, rewind, the
/compact handover) asks the registry. A live session still narrows rewind
through the adapter, and the host combines declared and narrowed in one
helper. The registry refuses a registration that declares compact, a thread
goal or rewind without the adapter method behind it.

/compact is admitted by the declared capability, so an agent that declares
compact:false gets the commandRefused fact instead of a thrown error.

Also: the cut-turn notice names the agent from the catalog, create-support
builds the account home through agentSessionAccountHome, and the turn
status text older clients read names the session's agent instead of
defaulting to Codex (Claude/Codex text unchanged).

* refactor(agent-session): the router applies the declared rewind itself

The router holds the registry, so its rewindSupport answers the owner's
declared rewind narrowed by the adapter, in one place no reader can bypass.
The host-side combining helper is gone; readers ask the adapter they hold.

* chore(agent-session): the registry is the one lookup; drop the test-only empty capability record

* test(native-chat): build the Stop-opened-turn test's identity and turn context the current way

The test (#25056) landed before the opaque provider handle (#24991), so main still built
the old {kind, threadId} handle; the turn context also needs this branch's agent registry.

* test(ratchet): require src/main/provider-process now that it has landed

* test(native-chat): keep main's opaque-handle import in the Stop-opened-turn test

Main's #25706 and this branch both added the import at different lines; the merge kept both.

Subject: [PATCH 081/167] Share the managed process lifecycle for structured
 providers (#25204)

* fix(native-chat): a child's root exit is reported even during its close, and bookkeeping after it never reads as unproven

- Both connections report the root process's exit once, with `expected` set when a close had
  begun. A close that came back unproven and whose root exits later is finished by the adapter,
  and its end reaches the host like any other.
- A Claude close whose resume-point write fails after the exit was proven, and a Codex close whose
  terminal row is refused, now end the session and report the failure, instead of keeping a dead
  child indexed as if its exit were unproven.
- A Codex close whose forced tree kill can't prove the descendants gone but saw the root exit
  reports the descendants and counts the root exit.
- Every child exit with an identity, expected or not, is forwarded to the host.

* fix(native-chat): the exit ends the child's record; an unfinished stop is the child's own close, which everyone joins

- The host keeps no stored "stop still owed" record any more. A stop begins the child's close
  (`child.close`), which lives on the child and ends with it. A second Stop, the idle reaper,
  quit, a send and an option/answer/goal/rewind all join that close instead of retrying a
  separate obligation.
- A caller waits on the close only as long as the step deadline; the close itself is never
  abandoned. A proof that lands after every caller stopped waiting reaches the host as the
  adapter's report of that exit, which ends the record through the same handler.
- Once the exit is proven, draining, settling, the lease release and the adapter's
  acknowledgement are each attempted and reported on failure; none keeps the child on record.
  A start, and the handle's close, write a release that failed from this host's proof of that
  exit, so a failed write never refuses a send.
- A start that meets a close still unverifiable is refused with `previousExitUnverifiable`, so the
  queued message is rejected with a send-again reason; nothing is held and nothing starts beside
  the old process.
- The idle sweep goes back to idle reaping only.
- Removes #24333's retry entry points, the wait row and its hold rule, the ask/failure cursors on
  the stored record, and the stop's own wake.

Tests replace the #24333 unproven-stop test: a send joining an unproven close and an in-flight
one, a late proof past the caller's bound, a root exiting after its close gave up, a proven exit
whose resume-point write and lease release both failed, an unverifiable close rejecting the send
and refusing an option change, a surviving descendant, quit and the idle reaper; and Codex's
unverifiable, late-exit and joined-close cases.

* fix(native-chat): a message refused because the old process's exit is unverifiable says so, and to send again

The start failure for a refusal with reason `previousExitUnverifiable` reads "Orca couldn't
confirm Claude's previous process ended. Send your message to try again." instead of "Claude
couldn't restart." The status-row kind and the refusal reason stay in the shared lists for rows
and hosts that still carry them; the catalogs keep one sentence for both.

* fix(native-chat): a close's verdict is the root's exit alone, and what follows it is logged

- A Claude close resolves as soon as the root's exit is proven: the session ends and its `ended`
  report goes out then. Saving the resume point runs afterwards and a failure is logged, so a slow
  or hung write never reads as an unproven exit or keeps a dead child on record.
- A root that exits after its close came back unproven finishes that close through the same path
  as any close, so the session's child work is published as ended (background tasks and subagents
  no longer stay shown running for a dead agent), and a failure there is logged.
- Codex logs a refused final row, and reports a root exit whose forced tree kill could not prove
  the rest of the tree gone the way Claude does, so the host logs it and blocks nothing.
- Both adapters take the host's logger for this bookkeeping.

* fix(native-chat): one handler ends every child's exit, and a join waits on the adapter's own close

- One exit handler (`structured-agent-session-child-exit`) ends a child's record for an exit
  expected or not. `expected` only changes what the chat is told: the stop's cause, its end at the
  stop's ask, the settlement id, and no crash outcome row. The lease release keeps the exit's
  evidence; the handoff guard, lifecycle barrier, sink release and adapter acknowledgement apply to
  both. A Claude journal-sink failure ends in the same step as its stop, as Orca's own fault.
- Joining a close is asking the adapter, whose close is memoized while it runs and bounded by its
  own kill escalation; the host keeps no attempt of its own and no 10 s caller bound. An ask after
  a close came back unproven runs the stop again.
- A close's end is stamped where its stop was asked for (a repeated ask moves it), so the closed
  chat and failed start checks order a message accepted meanwhile after it.
- A start refused because the old exit is unverifiable rejects what was queued in the same step.
- The end of a close the host asked for no longer waits on the cross-session recovery chain.
- The kill no longer waits for the stop event's write; the journal writes rows in order.

* fix(native-chat): an exit's lease release lands whatever the length of its reason

A crash's reason can carry kilobytes of the provider's stderr, and a lease whose death detail is
over 512 characters fails the store's own check. The exit handler cut it, but the release a start
or the chat handle's close re-derives did not, so after a crash whose own release failed every
message was refused as not resumable until restart. The record's builder now cuts the detail to
the record's bound, so no writer can hand it one too long.

* fix(claude): a proven close waits at most 2 s for the output it already wrote

Once the root's exit is proven, the close still waited for the SDK's output reader to end. Something
outside the process tree that holds the output open would keep that close, and every send, Stop
and quit joining it, waiting with no bound. The wait is now bounded; past it the close resolves as
proven and the open output is logged.

* fix(codex): an exit reported inside Orca's close keeps the reason Orca closed it for

The connection reports the app-server's exit inside the close that ends it, so that report ended
every Codex close and replaced the close's own reason (for example, a provider frame that could not
be recorded) with the connection's stderr text in the ended record and the lease's exit evidence.
The session now records Orca's close with its reason, and the exit it ends keeps that reason. The
test connection reports its exit inside close the way the real one does.

* fix(native-chat): quit stops delivery before it drains exit recovery

Every exit now wakes delivery, and teardown drained exit recovery before it stopped delivery, so an
exit settled in that window could start a fresh agent that teardown then killed. Teardown stops
delivery first; queued messages wait for the next launch.

* docs(native-chat): the unverifiable-exit refusal no longer names a caller's wait

The caller's bounded wait was removed; the comment describes the close as it is now.

* fix(native-chat): a stop whose kill did not take is logged, and the next ask kills again

When a close's kill leaves the agent's root running, the host now logs it. Tests pin what a later
ask does: each connection runs its whole stop again (Codex sends SIGKILL a second time), refuses
input meanwhile, and proves the exit once the kill takes.

* fix(native-chat): a start refused over the old process says Orca couldn't stop it

The host reaches an unverifiable verdict only after its own kill left the agent's root running, on
the machine that runs the agent, so the sentence now says that: "Orca couldn't stop {agent}'s
previous process." The refusal reason, failure kind and wire shapes are unchanged. The host test
also checks the failed kill is logged.

* docs(native-chat): an unverifiable close verdict is a root that survived the kill

The host's close runs where the agent runs, so lost contact never yields this verdict; the comment no longer says it does.

* fix(native-chat): a kill that did not take is reported once, by whoever met it

The log added at the close fired beside a Stop's own failure report for the same event. A stop
still reports it through its failure; a send or option change refused over it now logs it at the
refusal, the only place it is otherwise invisible.

* test(native-chat): a second Stop joins a close the first could not prove and retries its kill

* fix(native-chat): say a start refused beside an unstopped process plainly

The rejection now reads "Couldn't stop {{agent}} from before. Send your message again to try once more."
This kind has its own send-again step; every other failure keeps "Send your message to try again."

* Move provider process supervision and stream reading out of Codex

* Preserve teardown behavior with checked mock types after move

* Apply provider launch environment and caller teardown labels

* Share managed provider launch, exit observation, and close

* Preserve synchronous stdin closure before the grace wait

* Keep the stacked Claude adapter within the module size limit

* Handle nullable provider stdin and processless fixture identity

* Preserve close-time cleanup diagnostics after a late provider exit

* Separate provider root and descendant exit observations

* Give provider child env one owner and gate Codex contract on the shared reader

resolveProviderChildEnv is now the only place that overlays and strips a
provider's environment; the spawn spec and the request-scoped Codex session
both call it. supervisedPosixLaunch only accepts a launch without env fields,
so an override can no longer be silently ignored there. Edits to the shared
stream reader or the env rule now run the real-binary Codex contract job.

* Give every provider one close result, stderr tail and root-only default

- A close reports the root and the descendants with the one verdict vocabulary
  (live / unverifiable / exited); `tree` is null when the close made no
  descendant observation, and the fallback teardown's outcome is written into
  it instead of a side flag a caller could miss.
- The managed process drains stderr and keeps the 8 KiB tail, so no provider
  can forget to drain the pipe.
- Root-only providers take the default close policy and completion rule; only
  Claude overrides them. The one already-exited guard lives in the managed
  close and is recorded when no earlier close ran.
- A failed spawn is never read as an observed root exit.

* Report only observed descendant exits from the fallback teardown

The fallback teardown answered "accepted", and the close turned that into
`tree: 'exited'`, though a Windows tree kill's outcome is never read and an
unreadable process table observes nothing. It now returns what it observed:
`exited` only when the captured descendants were verified gone (or the kernel
reported the group empty), `live` / `unverifiable` as verification found them,
and null when it signalled without observing. Codex's process-tree diagnostic
fires in exactly the cases it did before.

* Give two test fixtures' casts a SAFETY rationale for the changed-code gate

* Claim no observation from an empty process group

ESRCH from the dedicated-group signal says only that the group is empty: a
descendant that left it, or a root that never led it, may still be running.
It now reports no observation instead of `exited`. The unreadable-table
comment says why that case stays "no observation" for root-only providers.

* fix(native-chat): a person's close joining a failed one still binds the turn its child end cuts

On main every close of the chat writes its own Stop and settle. Here a later close joins the
first and writes no row, and the first's settle closed when its kill failed, so a turn that opened
in between and was cut by the next close read as failed. A person's close joining a person's close
whose Stop opened a settle now reopens that settle until its attempt is done.

Tests: a close whose kill failed still closes its settle; a turn opened between a failed close and
the next reads as the person's cancellation (each fails without its half of the fix).

* test(native-chat): build the Stop-opened-turn test's identity with the opaque handle

The test (#25056) landed before the opaque provider handle (#24991), so main still built
the old {kind, threadId} handle.

* test(ratchet): require src/main/provider-process now that it has landed

* test(native-chat): keep main's opaque-handle import in the Stop-opened-turn test

Main's #25706 made the same fix as this branch at a different line; the merge kept both imports.

Subject: [PATCH 082/167] test(cross-version): load releases that import a
 package main dropped (#25731)

* test(cross-version): stand in for packages a release declares but main dropped

The newest release (v1.4.221) imports @streamparser/json, which main removed.
The harness runs release source against the current install, and the release's
RPC dispatcher imports its whole method table, so every wire suite failed at
import time. Extraction now gives each package the release declares and the
current tree no longer declares a stand-in in the checkout's own node_modules
that loads but throws, naming the package, on any use.

Co-Authored-By: Claude <noreply@anthropic.com>

* test(cross-version): decide stand-ins by package resolution, not manifest diff

A package gets a stand-in only when release source imports it at runtime,
the current tree does not declare it, and it does not resolve from the
checkout. A package still reachable from the checkout keeps the real install,
and one the current tree declares but cannot resolve stays a loud failure.
Type-only imports, comment prose and scripts in strings are ignored.

Subject: [PATCH 083/167] fix(markdown): strengthen dark table grid lines
 (#25653)

Strengthen only dark-mode table cell borders in Markdown Preview and the rich editor by mixing foreground into the existing border token. Keep light mode and table geometry unchanged.

Fixes #24982. Consolidates #24984, #25050, and #25653.

Subject: [PATCH 086/167] Bound file-search inventories and release abandoned
 Markdown data (#25369)

* Bound relay git-grep records and clean up capacity failures

Credits @OrcaWin for the original bounded-record proposal.

* Bound filesystem listing and transfer metadata at the execution host

Apply mobile limits before transport, list Markdown through its semantic producer, and retain complete directory results only within explicit capacity budgets. Stream SFTP directory packets and reject oversized transfer plans before reporting success; preserve narrow older-peer fallbacks and validate streamed response retention.

* Release inactive Markdown candidates and support folder scopes

Keep one current document snapshot per consumer and attach completion candidates to the actual editor model lifetime. Resolve folder workspace roots through existing workspace identities so their previews and completions receive the same authorized listing as worktrees.

* Preserve full runtime inventories under aggregate byte budgets

Leave unqualified inventories complete beyond 20,000 files. Charge retained paths and serialized bytes at local and relay producers, reject oversized full inventories explicitly, and bound old-peer response reassembly; keep caller-specific mobile and explicit result limits.

* Bound SFTP directory handle cleanup waits

Send CLOSE even after cancellation, stop waiting after five seconds without an acknowledgement, and ignore late callbacks. Preserve the original capacity or cancellation error and close handles returned after an aborted OPENDIR.

* Preserve registered root spelling in Markdown document paths

* Reject incomplete SFTP directory cleanup and final cancellation

* Bound pending response bytes before stream ownership arrives

* Preserve bounded directory reads on legacy SSH hosts

* Allow bounded per-chunk padding at response byte boundaries

* Bound response payload retention after stream metadata

* Bound complete legacy Quick Open inventories and cache retention by bytes

* Localize Markdown document listing fallback

* Exercise relay search decoding with real byte streams

* Preserve concrete relay stream fixture types

* test: compare distinct bundled ripgrep platforms on Windows

* Preserve Markdown discovery across Windows and legacy SSH hosts

* Make WSL process termination available to the bounds layer

Subject: [PATCH 087/167] Cancel abandoned file searches and prevent stale
 results (#25370)

* Bound relay git-grep records and clean up capacity failures

Credits @OrcaWin for the original bounded-record proposal.

* Bound filesystem listing and transfer metadata at the execution host

Apply mobile limits before transport, list Markdown through its semantic producer, and retain complete directory results only within explicit capacity budgets. Stream SFTP directory packets and reject oversized transfer plans before reporting success; preserve narrow older-peer fallbacks and validate streamed response retention.

* Release inactive Markdown candidates and support folder scopes

Keep one current document snapshot per consumer and attach completion candidates to the actual editor model lifetime. Resolve folder workspace roots through existing workspace identities so their previews and completions receive the same authorized listing as worktrees.

* Preserve full runtime inventories under aggregate byte budgets

Leave unqualified inventories complete beyond 20,000 files. Charge retained paths and serialized bytes at local and relay producers, reject oversized full inventories explicitly, and bound old-peer response reassembly; keep caller-specific mobile and explicit result limits.

* Bound SFTP directory handle cleanup waits

Send CLOSE even after cancellation, stop waiting after five seconds without an acknowledgement, and ignore late callbacks. Preserve the original capacity or cancellation error and close handles returned after an aborted OPENDIR.

* Preserve registered root spelling in Markdown document paths

* Reject incomplete SFTP directory cleanup and final cancellation

* Bound pending response bytes before stream ownership arrives

* Preserve bounded directory reads on legacy SSH hosts

* Allow bounded per-chunk padding at response byte boundaries

* Bound response payload retention after stream metadata

* Bound complete legacy Quick Open inventories and cache retention by bytes

* Localize Markdown document listing fallback

* Exercise relay search decoding with real byte streams

* Preserve concrete relay stream fixture types

* test: compare distinct bundled ripgrep platforms on Windows

* Preserve Markdown discovery across Windows and legacy SSH hosts

* Make WSL process termination available to the bounds layer

* Cancel abandoned file searches and preserve search keyboard navigation

* Invalidate searches when workspace roots or owners change

* Cover root replacement and legacy search cancellation together

* Exercise search cancellation through the current desktop access seam

* Keep search ownership and cancellation contracts current

* Share local text-search execution and close canceled subscriptions

Subject: [PATCH 088/167] fix(remote-runtime): a paired terminal accepts input
 again after its host app relaunches (#25736)

* test(remote-runtime): reproduce dead input after a paired host relaunch

A relaunched desktop host accepts RPC before its renderer publishes a window
graph. During that gap session.tabs.list answers with an unpublished empty
graph (publicationEpoch "none", snapshotVersion 0, tabs []). The client's
reconnect inventory treats that as removal and retires the pane
(retireRemoteTerminalId(-1)): the pane goes to "ended", the reconnect overlay
disappears, and keystrokes never reach the surviving daemon PTY.

Both tests are red on main by design; they are the repro for the fix.

- e2e: holds the relaunched host's runtime:syncWindowGraph so the client's
  reconnect deterministically meets the unpublished host (4/4 red).
- unit: transport-level repro of the same retirement (red in ~2s).
- restart helper gains a beforeFirstWindow hook; LaunchOptions moves to its
  own module to stay under the max-lines budget.

* fix(remote-runtime): a paired terminal survives its host app relaunching

After the host app quit and relaunched (daemon still running), a paired
client's terminal cleared its reconnect overlay and then ignored all input.
The relaunched host answers session.tabs.list before its renderer publishes,
with a synthesized empty frame. A paired client sees that frame through its
navigation projection as epoch "none:client-navigation", which the shared
"does this frame answer for the worktree" check did not recognise, so the
pane read it as removal and retired itself.

- hostSnapshotAffirmsWorktreeContents treats the client-projected placeholder
  as no answer at any version (the projection adds its navigation revision).
- The reconnect inventory keeps polling on such a frame instead of retiring;
  a published frame lacking the surface still retires the pane.
- Pushed frames that affirm nothing no longer report the surface absent.
- When the bounded inventory wait ends without evidence, the first published
  snapshot carrying the same handle now reattaches the pane, rather than
  waiting out the ~3 minute auto-recovery deadline.

Client-only: the host already labels the frame, old hosts send the same
frame, and the wire is unchanged. The e2e helper drops its type assertions.

* refactor(remote-runtime): simplify the host-relaunch reconnect fix

- One epoch rule: the placeholder epoch, bare or with the shared
  client-navigation suffix, is no answer. Hosts only ever send it at
  version 0, so the version check is dropped.
- Unpublished frames are dropped where pushed snapshots enter, instead of
  a nullable per-subscriber update.
- A published same-handle snapshot fires the parked retry through
  retryNow(), which now also fires a retry parked while still
  'recovering' (nothing is in flight then). This replaces state-reading
  wiring in the listener and lets online/resume fire it too.
- The Windows e2e runs the fixture through PowerShell's call operator.

* test(remote-runtime): prove the e2e hold beat the relaunched host's first publish

The spec now asks the held host for its tab list and requires the
unpublished placeholder before releasing, so a hold installed too late
fails instead of passing against unfixed code. The helper keeps its gate
in a typed global instead of Reflect lookups.

* fix(remote-runtime): keep a fenced handle's parked retry revivable

A retry parked for a handle that needs a replacement was consumed by an
early external trigger and then refused by the epoch's snapshot-wait
guard, leaving nothing to revive the pane. An external trigger now takes
over that snapshot wait as a fresh attempt, and a republished fenced
handle no longer fires the retry. Also refreshes comments that still
paired the placeholder epoch with version 0.

* fix(remote-runtime): a host answers an empty worktree for real once it has published

The host sent its unpublished placeholder for any worktree it had no
entry for, including one its window had never opened, long after
startup. With the placeholder now read as "ask me later", a paired client
opening such a worktree never got its first terminal.

The host now sends the placeholder only until its graph first publishes.
Afterwards a worktree with no tabs gets a real empty answer, and a client
that was told "ask me later" during startup is sent that answer once on
publication. Against an older host the client withholds the automatic
first terminal for such a worktree, which the user can still create.

A host push now fires only a parked retry, never cutting a scheduled
backoff short.

* chore(reliability-gates): reference the empty-worktree tests in gate commands

* test(remote-runtime): find the never-opened worktree by repo id on every platform

       "oracle": "Run one byte-identical six-terminal oracle against an isolated headed desktop host and an isolated headless `orca serve` host. Stage at least 1,000,000 xterm cells, hide all six warm managers, emit an initial working title followed by 30 timed real-PTY spinner frames and a final idle title per worktree, and observe a second real session-tabs subscription plus the production renderer store. Require exactly two transport envelopes and two title mutations per worktree, no decorative title crossing either boundary, and positive decoded-envelope bytes. Enable ordinary parking with the lossy retention budget disabled, require exactly one mounted manager and five parked tabs, at most 45% retained cells, no more than 16 MiB heap growth, and under 500 ms timer drift. In headed mode, require the host renderer to remain on its original workspace with zero target terminal managers mounted throughout client park, reveal, and live I/O. While a tab is parked, require authoritative terminal.read to observe new PTY output; reveal it and require the original PTY, a marker within the requested 5,000-row history, the parked marker, and post-reveal input/output. Drive 24 real PTY title trackers in distinct worktrees through 40 decorative spinner frames each, then 40 spinner frames alternating with Cursor's bare native identity redraw, using fake clocks. Require all 2,880 raw chunks exactly and zero host session-tabs publications, serialized bytes, renderer apply calls, and renderer store mutations. Continue decorative evidence beyond 30 minutes, require exactly one refresh per worktree per 15-minute lease through a FIFO spaced by at least 50 ms, and require all 24 viewer statuses to remain working and fresh; then require one exact semantic idle transition and one visible-output chunk per PTY. Require ordinary and interior-Braille title changes to publish. Drive 64 host PTYs through ten 80 ms synthetic title frames, require zero paired client events after the first frame per PTY while all 640 local frames remain observable, attach a late client and require one current frame per PTY, then require semantic bell and idle transitions on both clients. Reconstruct a legacy subscribed stream with no outputPause capability, hide a chatty pane, require no hidden xterm writes, reveal it, and require one authoritative snapshot plus continued live output. Drop and acknowledge output only for one original paired-client stream, prove the fixture process consumed input while the host model advanced and the client stayed stale, then require the command snapshot probe to replace that stream, repaint exact fixture output, preserve authoritative PTY identity and target-tab cardinality, and resume live I/O. For a client without a delivered sequence, require the first numeric probe to establish a baseline without replacement, a same-sequence probe to remain attached, and a later advanced probe to replace only that stream. Withhold the first encrypted shared-control ready frame, start one RPC, trigger a status-probe refresh, and require two connections, one host delivery, successful response, and zero retained request bytes. Admit 128 active streams, reject the 129th as retryable, release one stream, then require the retry to attach and publish a snapshot without multiplying retained subscribers. Disable terminal.paired-parking.v1 and require the same oracle to fail before parking, while the legacy limit-one fallback separately passes. Also preserve truncated first paint, ACK-starved same-PTY recovery, responsive silent-command snapshot probes, dead-stream probe timeout recovery, and queued manual-disconnect fencing.",

Subject: [PATCH 089/167] Stop repeated recovery of finished workers (#25679)

* Settle completed worker assignments and bound recovery retries

* Reset queued explicit recovery before starting its retry budget

* Use current provider identity in the inherited journal fixture

* Keep late worker recovery automatic without repeating persistence work

* Repair inherited validation fixtures after updating main

* Keep the released parser available to compatibility tests

* Limit recovery queries and background process inspection to pending work

* Verify historical repair safety and live SSH process retention

* Preserve the same provider import as main in the merge result

* Reduce historical repair and duplicate workspace recovery work

* Align startup prompt fixture with upstream Windows coverage

* Keep healthy worker repair indexed and read-only

* Align startup prompt tests with current main

* Keep pending terminal releases progressing during recovery retries

Explicit foreground status reads still work. Ten minutes of unchanged retries cause zero session writes and never revisit settled workers. Existing backoff remains capped at 30 seconds so late availability recovers automatically; timers stop on convergence or cancellation, and foreign identities never arm local timers.

Repair queries avoid scanning finished history and return without a write transaction when no stale worker exists; actual repairs re-read under the writer lock and remain atomic. The index is built once per database and adds maintenance on worker-state changes. One recovery pass resolves each workspace once and keeps no lookup cache between passes. A same-machine 100,000-assignment before/after run observed repair 37.75ms to 17.89ms, no-op scan 25.62ms to 4.35ms with zero mutations, and subsequent database open 37.42ms to 17.11ms; The later partial-index/read-only revision observed no-op repair 0.016ms, complete healthy database open 12.44ms, and first index-build plus repair/open 63.14ms for 100,000 assignments and 1,000 stale workers.

Subject: [PATCH 090/167] Improve Quick Open matching, file locations and
 recent history (#25371)

* Match Quick Open queries across path terms and identifier separators

* Honor ignored-file and symlink preferences on file inventory hosts

* Open pasted file locations and remember successful workspace file visits

* Verify bounded directory listing preferences across execution routes

* Preserve symlink preferences on legacy directory fallback

* Preserve bounded Quick Open terms and separator alternatives

* Revoke stale Quick Open selections and preserve literal file locations

* Validate recent Quick Open candidates independently on their host

* Use complete old-host inventory fixtures for Quick Open compatibility

* Keep Quick Open validation current across palette and workspace changes

* Route recent candidates through relay file listing dispatch

* Record Quick Open hook renders as test snapshots

* Localize Quick Open eligibility errors and search aliases

* Validate file inventory with bundled search and runtime preferences

* test: use directory junction fixtures on Windows

* fix: negotiate Quick Open policies with nested SSH hosts

* fix: refresh cached linked folders after target changes

* Retry stale expanded links after reads settle and targets recover

* Scope stale refresh request lifetime to the visible workspace

* test: seed linked-folder fixture before watcher startup

* Keep Quick Open responsive and compatible with older hosts

* Exercise directory discovery with unprivileged Windows junctions

Subject: [PATCH 091/167] fix(relay): commit the cell counter in one round
 trip; cells boot without the database (#25765)

* fix(relay): commit the cell counter in one round trip; cells boot without the DB

Step 2 (option B) cell image:
- One-round-trip counter commit at acquireActivity, releaseActivity and
  activateControl: the final counter UPDATE and COMMIT go as one simple-query
  message. Server errors mean COMMIT never ran (retry as today; 22012 = no row,
  rolled back and disambiguated outside the transaction); a lost connection is
  never retried.
- Cells skip the schema apply and region backfill, so they listen while the
  database is down and turn ready on their first successful query.
- G13: rehome target connection headroom folded into the existing NOWAIT
  UPDATE, excluding the host's own reservation by key.
- fixLevel on every runtime metrics line, plus declared (not applied) cell
  fix-level metrics and alert.
- Per-desktop drain disconnect-gap measurement from existing log lines.
- Census test that fails on floating database promises; fixes two shutdown
  sites. Lock-wait sample keeps the combined role.

* fix(relay): make the outdated-image alert creatable: one PromQL condition, 1 h lookback, fixed floor

A PromQL condition must be the only condition in its policy, and alerts on
log-based metrics may look back at most 25 h. Replace the 6-day/7-day design
with relay_cell_min_fix_level (tfvars, raised by a targeted apply after each
wave) and one query: a serving cell below the floor or reporting no level,
sustained 6 h. Drops the separate without-level metric.

* fix(relay): review fixes: gap-script ordering, wider promise census, fused-path guard, row-busy as scheduled

- Drain gap script: sort closes by time (gcloud exports newest first) and
  refuse an invalid drain start.
- Census: any floating promise in relay src, including callback-discarded
  and never-read ones, with a reviewed never-rejects list.
- Test the fused counter commit through the store the server builds, so a
  wrapper that stops forwarding commitWithFinal fails CI.
- Same-cap shadow gate: a row-busy refusal (the host's own release still
  holds its row) is a scheduled 503, like an own early retry. No client
  change.

* test(relay): judge drain redials by no host refused twice, not a refusal count

The row-busy count tracks how many releases are still in flight at the
dial (80 of 180 every run at 1 s, against a bar of 90). What matters is
that the release has finished by the next dial: assert no host is refused
twice, keep the time-to-placed p95 bound.

* fix(relay): cap row-busy as scheduled at the drain-return admissions; bound the gap script's window

Shadow gate: a row-busy refusal of a drained host follows its drain-return
lane admission, so per minute only that many (plus a rounding margin of 2)
are scheduled; the rest stay non-drain, so row contention the drain does
not explain still fails the budget. Gap script: --drain-ended-at excludes
the new container's closes after the roll; later grants still close a gap.

Subject: [PATCH 092/167] fix(native-chat): ignore the terminal launch command
 when starting a native chat (#25720)

A custom launch command in settings made structured native chat unavailable:
the renderer route, the host launch-mode decision, and the host's
create-support all treated it as terminal-only, so a user with the chat
default on silently got a terminal. The command names the CLI binary and now
applies to terminal launches only; native chat ignores it.

A start directory outside the workspace still forces a terminal. The internal
route field and blocker are renamed to that concept; the wire reason
`tui_launch_command` is kept and its receipt text now names the start
directory.

Subject: [PATCH 094/167] Add chat appearance settings: text size, code size,
 width (#25657)

* feat(native-chat): add chat-scoped color tokens

* feat(native-chat): soften transcript and composer appearance

* fix(native-chat): refine code spacing and faint text styling

* fix(native-chat): wrap prose links at word boundaries

* test(native-chat): refresh background task strip snapshots

* Add native chat appearance settings and card scaffold

* Persist chat text and code sizes with appearance width controls

* Fix chat appearance typing, shortcut routing, and scoped typography

* Use chat call identities in typography regression fixture

* Keep markdown metadata typography independent of chat text size

* Preserve terminal undo chords and stabilize chat resize estimates

* Show only primary shortcuts in chat appearance settings

* fix(native-chat): preserve appearance edits and configured zoom shortcuts

* Remove unused chat appearance summary translation

* Preserve command classification when applying chat code size

Subject: [PATCH 095/167] Admit one provider event's journal writes as one
 queued operation, decided when it runs (#25141)

* Move the turn message ordinals and the turn-row revision to the neutral timeline folder

Pure moves so a shared timeline assembler can use them: Codex's message
ordinal counter becomes ProviderTurnMessageOrdinals and Claude's turn-row
revision becomes the provider-neutral agent-journal turn-row revision. Only
names and import paths change.

* Admit one provider event's writes as one transition, and let rows be found again after a restart

- A sink transition is admitted whole or not at all; its steps run back to
  back at their turn in the journal's write queue, and each resolver reads
  the fold with every earlier write landed. A resolver may also say where the
  row belongs (turn scope, provider reference), and the writer always hears
  how the transition landed. A resolved lifecycle batch chooses its
  settlement mutations from the fold at execution.
- New optional row field providerItemRef: the provider's own reference for
  the item a row is, written only where the row's identity cannot spell it
  (Codex keys messages by their place in the turn and renumbers its item ids
  on resume). Set by the creating write, kept by revisions, indexed by the
  journal fold, never read by clients. A downgrade test shows an older host
  and client render such rows unchanged.
- Provider timeline identity schemes (shared legacy arm, Codex) and the join
  index that resolves a provider item to its row from memory or the fold:
  ordinals and request incarnations are read back from the rows, so a
  restart or an evicted entry finds the original row instead of placing a
  new one.

* Recover message ordinals from the journal's highest place, and forget joins read from a replaced epoch

A fresh join index continued a turn's messages at the first free place, so a journal holding only a
later ordinal (an imported or removed earlier row) had its sequence back-filled. The place is now
one past the highest ordinal any row or echoed send holds there, read through a pure scheme reader.
The join caches also drop what they read when the journal's epoch is replaced.

* Spell the subagent thread's message slot without spreading an identity union

* Keep the journal store under its line limit after the main merge

* Drop the provider item reference, join index and identity schemes from the transition PR

Nothing in production reaches the state they defended (an assembler that lost its memory while
its child keeps streaming the same turn), and the stored Codex id was positional. The legacy
identity scheme moves to the assembler PR with its first caller; the Codex scheme and any
persisted reference wait for Codex to move onto the assembler. The Codex ordinal counter goes
back to codex/, since no neutral code imports it.

* Write a resolved settlement in one transaction through enqueueRows

A settlement too large for one row now commits all its rows or none, through the journal's
existing all-or-nothing write, instead of a row-by-row writer. Every row is built before any
commits, so a settlement naming one item twice is refused before anything is written.

* Drop the transition's landing report; keep the turn-row write fire-and-forget

Nothing reads which steps of a transition wrote. A failed step fails the sink, leaving the
steps before it written; the header says so, and tests cover it plus a settlement whose second
row fails inside the transaction. writeAgentJournalTurnRow returns nothing again, as on main.

* Run a transition's steps as a prefix; drop the paced flag and resolved options

A failed step no longer lets the steps after it write: each step checks, at its own turn in the
journal's queue, whether the write handed over just ahead of it completed, using the queue's count
of completed write bodies (a promise would report the failure only after the next step ran). The
sink fails only once every step has had its turn. The item step's `paced` size bypass and the
resolver's replacement `options` are removed; nothing planned uses them.

* Run a transition's steps in one queued write that loops over them

The steps of one event now share one turn in the journal's write queue: a
loop writes each in its own transaction through the row writer's
synchronous writeRows (split out of enqueueRows) and stops at the first
throw. Prefix semantics and "nothing lands between the steps" now hold by
construction, so the completed-write counter on the queue, the step gate
and the allSettled barrier are gone; the queue is back to main's bytes.

* Use current provider handles in transition tests

 - **File paths**: Use `path.join` or Electron/Node path utilities — never assume `/` or `\`.
 - **Windows terminal shells**: `--shell` picks the shell a terminal _is_; `--command` is typed into whatever shell the host spawned, so a shell choice routed through `command` silently becomes a child process. See [`docs/reference/windows-terminal-shell-selection.md`](./docs/reference/windows-terminal-shell-selection.md).
 - **Windows setup scripts**: the setup/issue-command runner is a `.cmd` batch file unless the script starts with a `#!` line — never derive that from the user's terminal-shell preference, and never launch a `.cmd` runner with a bare `cmd.exe /c` from a Git Bash pane (MSYS rewrites the `/c`). See [`docs/reference/windows-setup-shell.md`](./docs/reference/windows-setup-shell.md).
-- **Windows child processes**: start them through `runProcess`/`spawnProcess` in `src/shared/child-process/` — never `child_process` directly. It pins `windowsHide`, refuses `shell: true`, and encodes `.cmd`/`.bat` arguments so neither `CommandLineToArgvW` nor `cmd.exe` mangles them. A ratchet test fails on any new direct import. Recognised npm/pnpm `.cmd` shims are resolved to their real target so the spawn skips `cmd.exe` entirely; see [`docs/reference/windows-cmd-shim-resolution.md`](./docs/reference/windows-cmd-shim-resolution.md) before adding a shim shape or debugging one.

 - **Ripgrep**: Orca bundles `rg` for every platform, WSL, and SSH remotes. Spawn it through `spawnBundledRipgrep` (main) or `resolveRelayRipgrepCommand` (relay), never a bare `'rg'` — Windows resolves a bare name in the spawn cwd before PATH. Don't add git/readdir fallbacks locally; the relay's chain exists only for hosts an upload never reached.
 - **Windows process enumeration**: read the table through `src/main/windows/windows-process-table.ts`, never by forking `powershell.exe`. See [`docs/reference/windows-process-enumeration.md`](./docs/reference/windows-process-enumeration.md).
 - **Windows MSYS/Git Bash panes**: their children break away from the per-PTY job unless it is created without `JOB_OBJECT_LIMIT_BREAKAWAY_OK`, and a `conpty.node` built before that fix passes every existing gate. Before changing the per-PTY job or debugging `windows-msys-job.win32.test.ts`, read [`docs/reference/windows-msys-job-breakaway.md`](./docs/reference/windows-msys-job-breakaway.md).

- * grow, and that the entry is read before it ships rather than found on a device.
- *
- * What is NOT here is the point of the census. `files/[worktreeId] -> files/preview/[worktreeId]`
- * is absent because the preview declares no more than the explorer, so that hop stays in the
- * document — which is C3.1's pairwise pin, now a consequence of the rule rather than a rule of its
- * own. Absent for the same reason, and measured rather than reasoned: the four hops the worktree
- * list and the history screen make into the explorer and its preview, which left this list when
- * those two declared the `externalLink` their own protocol wall reaches and took it from 23 rows
- * to 19. The four now declare the same four grants, so a tapped file costs no native frame and no
- * second bridge session.
- *
- * What remains beside the session rows is twelve: four openers holding no `native.clipboard.write`
- * into the three routes that ask for it — tasks, the hub and review.
- *
- * Absent for the same reason, and the reason C4 registered its two routes in one PR:
- * `source-control ⇄ review` in both directions. The hub's rows push review and review replaces
- * back, and the two declare the same five grants, so both hops stay in the document. Either one
- * landing alone would have put a handoff — a new native screen and a new bridge session — between
- * a changed-file row and its diff.
- *
- * The seven C7 rows are the same rule with the arrows all one way: every one `X -> session`, one
- * from each other page route. The session screen's thirteen grants are a strict
- * superset of every other route's, so nothing can reach it under the grants it was opened with —
- * and nothing it pushes to leaves, because its own seven targets each declare a subset. A row in

-
-## The guard
-
-`src/main/wsl/wsl-probe-failure-semantics.test.ts` scans the WSL and preflight
-probe modules for `catch { return false | [] | null }` and holds the current set
-in an allowlist that only shrinks.
-
-Its limits are worth being explicit about, because they decide how much it is
-worth trusting:
-
-- **It cannot see the dangerous part.** Whether a swallowed value is later
-  cached or gates discovery is dataflow, not syntax. Every allowlisted entry is
-  currently safe; the guard does not verify that and cannot.
-- **It is scoped, not global.** The same shape appears ~850 times across `src/`
-  and is usually correct, because for most callers a failure genuinely does mean
-  absent. Enforcing it repo-wide would be noise. It only matters where the
-  answer describes a WSL distro.
-- **It catches a shape, not a mistake.** Code can conflate failure and absence
-  without ever writing `catch { return false }`.
-
-So it does not prevent the bug. What it does is stop a new swallow site
-appearing in these modules without someone stating why the value is safe to
-pin — which is the review conversation that was missing all three times.
+Whichever you pick, document why the fallback is safe for callers to cache or use for discovery.
+
+## Reviewing failure fallbacks
+
+Review the caller as well as the catch: whether a fallback is cached or gates discovery is a dataflow question. Returning `false`, `[]`, or `null` after a failure can be safe for some operations, but a WSL probe must preserve the distinction between absence and a distro that could not be reached. Prefer behavioral tests that exercise probe failure, discovery, caching, and recovery together.

-- **`fork` is not scanned.** Node forwards `windowsHide` to spawn at runtime, but `ForkOptions` does not declare it, so the two live sites — `main/daemon/daemon-init.ts` and `main/plugins/plugin-host-process.ts` — cannot be fixed without a cast. Both are console-subsystem children on Windows.
-- **The allowlist is file-granular, so an allowlisted file is blind.** ~18 of its entries are false positives (`RegExp.prototype.exec`, `provider.exec`, and files the lexer desynced on), and each carries a standing pre-approval for a real regression in that file. Those entries also cannot be retired by fixing code, so the list cannot reach zero as written. Making it call-granular is the fix.
-- **`stripComments` has no desync report.** The fail-closed check runs on already-stripped text, so a regex literal containing a slash-star can still swallow code silently. No occurrence in `src/` today.

-Plant a violation and watch it fail. Every guard fix in this workstream that was verified only by reading was wrong — three consecutive attempts at an exact lexer each shipped a desync that _reduced_ the offender count, which read as progress. Plant at least: a plain call, one in a template-literal-heavy file, one in a regex-heavy file, `windowsHide: false`, a ternary first argument, and a renamed import.

- * A Back control the page serves is reachable by name or not at all. Inside the shell there is no

- * What makes a control a Back control here is what it does, not what it draws. A glyph does not

- * already says Back; a control matching neither is outside this rule whatever it renders.
- *
- * The label half of that predicate would be circular on its own — a control with the wrong label
- * and an opaque handler would simply not be found — which is what the presence assertion below is
- * for: a screen that yields no control at all fails. One of the five depends on it today, the host
- * screen, whose `actions.leaveHost` is a member access this rule does not follow; the other four

-/**
- * Every production `killWithDescendantSweep` call must pass `terminateOwnedTree`.
- *
- * Why a scan and not a type: the option is optional by design — a POSIX-only
- * caller has no job to offer — so nothing makes omitting it an error. And the
- * cost of omitting it is invisible in review: the sweep silently falls back to
- * a parent-pid walk that a detached, reparented grandchild is not in, so the
- * process holding the worktree cwd survives the delete (#9045, #10475, #10897).
- * That is exactly the shape #11047 measured: the job was wired into
- * `local-pty-provider.ts`, worktree delete ran through the daemon instead, and
- * the fix engaged on neither of the paths that actually execute.

- *   is replayed chunk by chunk into a real runtime pane at its recorded grid, once with the agent
- *   known and once agent-unknown. Each frame records the ranked verdict the moment the chunk lands
- *   and had the stream then gone quiet, what `terminal wait --for tui-idle` started there returns
- *   (at once or on its first poll tick), and the same on a clockless (restored or adopted) pane.
- * - Synthetic (readiness-census-synthetic.test.ts): every TuiAgent under a bounded matrix of title,
- *   first-party status, screen, foreground process and output clock
- *   (readiness-census-synthetic-matrix.ts says which cross-product and why).
- *
- * Baselines live in __fixtures__/readiness-census/, one per replayed pane (run-length encoded per

- *
- *   UPDATE_READINESS_CENSUS=1 pnpm test src/main/runtime/readiness-census

- *
- * `catch { return false }` is not itself the bug -- an uncached caller just
- * asks again and the answer corrects itself. The bug is what happens when that
- * value is cached or used to gate discovery: a distro that was busy for one
- * second reports no git, or no agent sessions, for the rest of the session.
- * It has shipped that way at least three times (see the allowlist header).
- *
- * A repo-wide rule is not workable -- the shape appears ~850 times in `src/`
- * and is usually correct, because for most callers a failure genuinely does
- * mean absent. It is only dangerous where the answer describes a WSL distro,
- * which is why the scan is scoped to the probe modules that own those answers.
- *
- * This guard cannot see the dangerous part. Whether a swallowed value gets
- * pinned is dataflow, not syntax. What it can do is stop a new swallow site
- * from appearing in these modules without someone saying out loud why it is
- * safe to pin -- which is the review that was missing all three times.

Subject: [PATCH 097/167] feat(github-projects): render Board project views as
 a kanban with drag-and-drop (#19074)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* Add board layout support for GitHub project views

Board-layout views render as a kanban. Columns come from the view's
verticalGroupByFields (the host retries without the selection on older
GHES schemas and the renderer falls back to the Status field), with one
column per single-select option in option order — empty ones included —
plus a trailing no-value column whose drop clears the field. Card drops
reuse the table's field mutation path, committed from a document-level
capture listener because the preload's native-drop bridge stops drop
events before React's root ever sees them.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* fix(github-projects): harden board capability probe and drop lifecycle

Review follow-up. The verticalGroupByFields capability probe now matches
parsed GraphQL error messages instead of substring-scanning the whole
response body — partial-error responses echo the field name as a data key
on healthy schemas, so one SAML/FORBIDDEN partial error could permanently
degrade github.com boards for the session. Covered by new
project-view-config tests per the capability-cache testing contract.

Also: only single-select/iteration vertical fields shape columns (a
drifted field kind no longer yields a clear-on-drop no-value column),
optimistic patches resolve the column field through the board/group
config, drag cleanup moved to a document-level dragend listener, the
column dot follows dark mode via the chip CSS variables, the supported-
layout allowlist is a single shared predicate, and the board's edit
handler is stable so its drop listener stops re-registering per render.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* fix(github-projects): serialize board edits and verify rendered drops

* fix(github-projects): preserve refresh baselines and order edits across views

* fix(github-projects): accept source settings projection in cache scope

* fix(github-projects): distinguish view switches from refreshed field baselines

* test(github-projects): type board IPC recordings and verify clear request

Subject: [PATCH 098/167] Add standalone Agent Client Protocol client layer
 (#24990)

* Add standalone ACP protocol client and session runtime

* Protect ACP transport teardown from late stream errors

* Retire incoming ACP request ids before publishing responses

* Narrow ACP configuration requests and transport message types

* Remove redundant ACP request handler return unions

* Keep ACP waits caller-owned and preserve protocol extensions

* Preserve open ACP decisions through prompt completion

* Generate open ACP enums and check the generated schema offline

A newer or vendor enum value (tool kind, tool status, option kind, stop
reason) no longer fails the whole message: generated enums accept the known
literals plus any other string, typed so callers can still narrow on the
known ones. The generated header now records the pinned input digests, the
generator digest and a body hash, so `verify:acp-protocol` catches a stale or
hand-edited file without network access; it runs in lint and the PR workflow.

* Land the ACP runtime contract the agent adapters use

- Deliver notifications other than session/update through
  onExtensionNotification, in arrival order with session updates.
- Accept _meta on prompt, setMode, setModel, setConfigOption and cancel.
- cancel() always sends session/cancel once the session runs, since the
  agent can be in a turn it began itself; only a successful send is shared,
  so a failed write is retried.
- Cancel aborts each open agent request's signal and lets its handler send
  its own answer; -32800 only when the handler rejects.
- Permission requests validate only the session, tool call id and options;
  unreadable fields are dropped with a diagnostic, and any answer Orca
  cannot send is `cancelled` instead of a JSON-RPC error. Agent-started
  turns may ask; whether to show it is the caller's decision.
- AcpAgentError marks the agent's own errors; AcpInvalidResponseError keeps
  the raw answer and validation issues for answers Orca could not read.
- Lines over the size limit are classified by prefix (shared with the Codex
  reader): the owed request fails, an oversized agent request is answered
  with an error, and an unattributable response closes the connection.

* Answer every agent request after an ACP cancel

A cancel that lands before a permission handler starts now still runs the
permission path, so the agent gets the `cancelled` outcome rather than a
request-cancelled error. A handler that ignores the abort no longer leaves
the agent waiting: once the abort has run through, any request still
unanswered gets request-cancelled. Handlers that answer on abort keep their
own reply.

Also renames a lint-rejected helper parameter, replaces a Reflect.apply in a
test, and stops the permission diagnostic from firing with an empty list.

* Let each ACP request handler own its answer after a cancel

Removes the next-event-loop-turn fallback that answered request-cancelled
for any handler still silent after a cancel. It raced answers that were
still being saved (an approval mid-journal-write reached the agent as an
error) and made the outcome depend on event-loop timing. The handler that
owns an agent request now always sends its answer, or throws for
request-cancelled; a request it never answers ends when the connection
closes. A permission whose handler had not started still answers
`cancelled`.

* Register the ACP schema verify step in the PR preflight phase test

* feat(acp): a steer's cancel asks once and never ends the agent

The runtime had one cancel: send session/cancel, wait at most 10 s for Orca's prompt to settle,
then close the connection, which ends the agent. A steer used it too, so a slow agent lost its
process just because the person added a message. requestSteerCancel() now sends session/cancel
once per prompt, cancels the agent's open requests and answers later permissions cancelled, and
never bounds or closes: the prompt's own reply ends it and the steer's prompt follows. cancel()
stays the Stop: bounded, then close. A Stop after a steer still bounds and closes. Both cancel
paths move into acp-prompt-cancel.ts over one cancel channel.

* fix(acp): a repeated steer shares the cancel in flight; say what the caller owns

Per review: a second steer before the first write lands returns that write instead of resolving
early. The steer's JSDoc says the wait for the prompt's reply is unbounded and that a prompt that
fails instead must not take the steer until the caller rebuilds the session; the Stop's says a
prompt that settles in time leaves the agent for the Stop's owner to end. The steer test now gives
the runtime a handler that would allow: the open permission's signal aborts and the late one never
reaches it.

* test(ratchet): require src/main/acp now that this PR lands it

+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must

+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or

+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.

Subject: [PATCH 099/167] fix(native-chat): start a Codex chat without waiting
 on the background model probe (#23831)

* fix(native-chat): start a Codex chat without waiting on the background model probe

Opening a Codex chat kicks a session-less model-catalog probe (a throwaway
read-only `codex app-server`) for the account, and the new chat's own
options read then joined that probe's in-flight refresh through the catalog
store's single-flight. When the probe's Codex hung, chat start waited out the
probe's 15s deadline and failed with "codex app-server session exceeded
15000ms", even though the chat's own app-server was up.

Single-flight now joins only a refresh by the same kind of lister. A live
session lists over the connection it already holds; the probe still records
its own failure in the store, and the picker keeps serving whichever listing
succeeded.

* fix(native-chat): never let a chat's model listing join another chat's listing

Single-flight in the model catalog store was split by lister kind, so a new
chat's acquire-time options read no longer joined the session-less probe,
but it still joined any other live chat's in-flight listing for the same
account. When that other chat's Codex was wedged or closing, the new chat
waited out that chat's request timeout and failed to start with its error.

Key in-flight listings by the lister's identity instead: a live session by
its own connection, the probe by the probe itself. A lister still joins its
own in-flight listing, and shouldRefresh still holds back a probe while any
listing for the account is in flight.

* test(native-chat): pin that the catalog store releases an account once every listing settles

shouldRefresh reads 'any listing in flight for this account' from whether the
per-account in-flight map exists, so that map must be dropped exactly when its
last listing settles. Nothing covered this: removing the cleanup, or dropping
the map on the first settle, passed every catalog test. A leftover map would
stop every later background refresh and probe for the account.

* fix(native-chat): name the catalog lister type instead of a bare object

A live session is keyed by its per-spawn catalog handle (minted in the same
acquire as its connection), the probe by itself.

* test(codex): pin that a chat's own concurrent option reads share one listing

* fix(native-chat): keep model picker current across parallel listings

Subject: [PATCH 101/167] Add a shared timeline assembler for structured agent
 chats (not wired yet) (#25064)

* Move the turn message ordinals and the turn-row revision to the neutral timeline folder

Pure moves so a shared timeline assembler can use them: Codex's message
ordinal counter becomes ProviderTurnMessageOrdinals and Claude's turn-row
revision becomes the provider-neutral agent-journal turn-row revision. Only
names and import paths change.

* Admit one provider event's writes as one transition, and let rows be found again after a restart

- A sink transition is admitted whole or not at all; its steps run back to
  back at their turn in the journal's write queue, and each resolver reads
  the fold with every earlier write landed. A resolver may also say where the
  row belongs (turn scope, provider reference), and the writer always hears
  how the transition landed. A resolved lifecycle batch chooses its
  settlement mutations from the fold at execution.
- New optional row field providerItemRef: the provider's own reference for
  the item a row is, written only where the row's identity cannot spell it
  (Codex keys messages by their place in the turn and renumbers its item ids
  on resume). Set by the creating write, kept by revisions, indexed by the
  journal fold, never read by clients. A downgrade test shows an older host
  and client render such rows unchanged.
- Provider timeline identity schemes (shared legacy arm, Codex) and the join
  index that resolves a provider item to its row from memory or the fold:
  ordinals and request incarnations are read back from the rows, so a
  restart or an evicted entry finds the original row instead of placing a
  new one.

* Recover message ordinals from the journal's highest place, and forget joins read from a replaced epoch

A fresh join index continued a turn's messages at the first free place, so a journal holding only a
later ordinal (an imported or removed earlier row) had its sequence back-filled. The place is now
one past the highest ordinal any row or echoed send holds there, read through a pure scheme reader.
The join caches also drop what they read when the journal's epoch is replaced.

* Spell the subagent thread's message slot without spreading an identity union

* Add a provider timeline grammar and a shared assembler that decides at its turn in the journal

Adapters translate their provider's dialect into a small grammar (turns,
items, streamed text, requests, context facts, session end/reset); one shared
assembler turns it into the journal rows every structured lane writes.

Each event is planned as one sink transition. Which row a write lands on,
whether a replay writes anything, and every change to what the assembler
knows (its ledger) are decided by the transition's resolvers at the event's
turn in the journal's write queue, against the fold as it stands then. A
forecast (the ledger plus admitted events still queued) only answers apply()
at once. So a refused event allocates nothing, a write the journal rejects
leaves no trace in memory, and a restart or evicted cache finds the same rows
again. Text and full snapshots of one provider item share one row and one
lifecycle; reset always flushes text and settles the old session from the
journal; the open-work budget is derived from what is actually open.

Codex migration contracts compare against the existing Codex translator,
including a restart mid-stream and a repeat that outlives the join cache.

* Fix the types and the exhaustive event switch CI reported for the assembler

* Let the journal decide stream lifetimes, request reuse, named sends and background work

A third review found two blockers with the earlier rounds' cause, a remembered interpretation
trusted after the journal moved on:

- A reused request id was judged by its earlier prompt's settled turn before asking which turn the
  new one lands in, so a real approval in a later turn was dropped. The target turn now decides:
  the old turn again is a replay; a different live turn opens the next prompt beside it.
- A text stream checked its row's turn only on its first write, and a turn's end released streams
  by the turn planning expected. Every write now checks the row, a turn's end stops the streams
  whose rows are in it, and turn status reads the journal first, so another writer's Stop wins.

Also: a message boundary drawn by an event the journal held as a replay no longer splits an
anonymous message; a send naming a turn not yet open waits for that turn; the budget charges a
stream's thread and turn strings and the turn caches are byte-bounded; the open turn ends when the
journal shows it settled; a turn's opener is read from the journal's row.

Background work is now Orca's existing background-task row instead of a tool call flagged
`outlivesTurn` (a flag remembered only in memory, so a restart failed the task). A turn's end
never settles that row, so it survives restarts; session end leaves one in flight unverifiable.
Three tests that opened a background tool call with `outlivesTurn` now open a background-task row
and keep their original expectations about which turn the row stays in.

* Type the unbound assembler helper's drain as the void it reports

* Bound the rows kept for a continued anonymous message and the stopped streams

A row kept for the anonymous stream that may continue it, and the marker that a stopped stream's
queued writes write nothing, lived in the live-stream map and were never removed when no stream
followed. They now live in their own bounded maps, so the live map holds open streams only.

* Keep the journal store under its line limit after the main merge

* Drop the provider item reference, join index and identity schemes from the transition PR

Nothing in production reaches the state they defended (an assembler that lost its memory while
its child keeps streaming the same turn), and the stored Codex id was positional. The legacy
identity scheme moves to the assembler PR with its first caller; the Codex scheme and any
persisted reference wait for Codex to move onto the assembler. The Codex ordinal counter goes
back to codex/, since no neutral code imports it.

* Write a resolved settlement in one transaction through enqueueRows

A settlement too large for one row now commits all its rows or none, through the journal's
existing all-or-nothing write, instead of a row-by-row writer. Every row is built before any
commits, so a settlement naming one item twice is refused before anything is written.

* Drop the transition's landing report; keep the turn-row write fire-and-forget

Nothing reads which steps of a transition wrote. A failed step fails the sink, leaving the
steps before it written; the header says so, and tests cover it plus a settlement whose second
row fails inside the transaction. writeAgentJournalTurnRow returns nothing again, as on main.

* Run a transition's steps as a prefix; drop the paced flag and resolved options

A failed step no longer lets the steps after it write: each step checks, at its own turn in the
journal's queue, whether the write handed over just ahead of it completed, using the queue's count
of completed write bodies (a promise would report the failure only after the next step ran). The
sink fails only once every step has had its turn. The item step's `paced` size bypass and the
resolver's replacement `options` are removed; nothing planned uses them.

* Rebuild the timeline assembler on one admission-order state

The assembler kept a second copy of its state (a forecast beside a ledger), hydrated
the open turn from the journal, and recognised replays, all to recover from losing its
memory while the provider child kept streaming. That never happens: one assembler lives
exactly as long as one child, and a new child is a new assembler in a new generation
whose events land after the dead-generation sweep.

- One state, changed only when the sink admits an event (minted keys included), so a
  refused event takes nothing.
- Every journal-dependent choice is made when the write runs, by keyed reads: a turn row
  is written only where none is, a stream checks its row's turn on every write, a running
  snapshot never lands in a settled turn or relights a settled tool, a request takes the
  first incarnation the journal holds no row for.
- Rows are found by spelling their ids (provider-timeline-rows.ts); no join cache.
- The identity scheme (legacy arm only) lives here with its first caller; requests are
  spelled in their acquisition generation, since JSON-RPC ids restart per process.
- Saved history goes in as `input.history` plus ordinary events with the provider's ids,
  into an empty journal; `session.reset` and every replay rule are gone.
- One terminal-body function (`terminalAgentJournalBody`) is shared with the
  dead-generation settlement.
- The test rig's restart now sweeps and starts a new generation, as production does.

* Cover new running work in a turn the sweep ended

* Run a transition's steps in one queued write that loops over them

The steps of one event now share one turn in the journal's write queue: a
loop writes each in its own transaction through the row writer's
synchronous writeRows (split out of enqueueRows) and stops at the first
throw. Prefix semantics and "nothing lands between the steps" now hold by
construction, so the completed-write counter on the queue, the step gate
and the allSettled barrier are gone; the queue is back to main's bytes.

* End a turn another writer settled the way the provider's end does

A person's Stop settled the open turn's row without a word to the assembler.
The assembler then forgot the turn: its running tools and pending prompts were
never settled, the provider's own end and withdrawal were dropped, and the
turn's text streams stayed counted against the open budget for the life of the
process. Text the provider kept streaming afterwards could land as a message
outside the stopped turn.

- The open turn the journal shows settled ends first, as one transition, through
  the same settlement the provider's turn.end plans; its streams stop and their
  keys drop later text until that turn's end or the next turn opens.
- turn.end and request.withdrawn are admitted for a turn or request the journal
  holds; their settlement writes nothing for rows already settled.
- The budget's re-check frees streams whose turn settled.
- A settled tool keeps its terminal body against any differing write.
- Session-end settlement of lost background work uses the journal's own
  lostLiveWorkJournalBody instead of a copy.
- The rig's window elapses before every read, and restart swaps and disposes
  the old assembler.

* Leave a stopped turn's running tools to the agent's own end

When another writer settles the open turn (a person's Stop), the assembler
now only stops that turn's text and cancels its pending prompts. Running tool
calls stay the agent's: a progress update or completion it reports after the
Stop lands as reported, and whatever is still running settles at the agent's
turn end for that turn, the next turn's open, or the session's end.

An agent's end for an earlier turn while a newer one is open no longer clears
the open turn's activity line or ends its anonymous reply. An unnamed end right
after a Stop ends the stopped turn instead of being dropped. The test rig's
restart no longer writes the dead assembler's window text, matching dispose.

* Pin that a stopped turn's running tools hold budget until the agent's end

* Type the stopped turn's tool progress update as a tool body

* List every event the assembler hands to the decision step

The type-aware lint requires an exhaustive switch with no default case.
Also retitle a Stop test to say what it asserts.

* refactor(native-chat): drop saved-history adoption from the timeline assembler

The common pattern discards the history a provider replays while loading a
session, so the assembler has no use for an input.history event.

* refactor(native-chat): a pending input is only Orca's send now

Review follow-up to the adoption removal: drop the comment naming the
provider's saved message, and make requestedAt required since every pending
input comes from input.accepted.

* Use current provider handles in transition tests

* Use current provider handles in timeline fixtures

+// The narrow grammar a provider adapter speaks to the timeline assembler.
+//
+// The adapter knows the provider's dialect; the assembler knows the timeline. An adapter parses
+// provider traffic into these semantic events and never writes a journal row or mints a journal
+// identity: every key here is the provider's own id (a turn, a tool call, a message, a thread),
+// or a name the adapter keeps stable for something the provider does not name. The assembler
+// spells those keys as row ids, scopes rows to turns, and owns the turn and item rules in
+// `agent-session-journal-types.ts`.
+//
+// Rules an adapter can rely on:
+// - One assembler lives exactly as long as one provider child: a new process is a new assembler,
+//   with a new acquisition generation.
+// - Only `turn.open` opens a turn. Items, text and requests never do: one that arrives with no
+//   turn open and names none is written as a thread row. An adapter whose provider starts work on
+//   its own (a background wake, auto-compaction) decides that a turn began and says `turn.open`
+//   before that work's items.
+// - `join.turn` attaches a row to the turn the provider says it belongs to, open or not.
+// - A turn settles once, with only the provider's verdict. A row the journal already holds is
+//   never written back to an earlier state: a settled turn stays settled, a settled tool keeps its
+//   terminal body, an answered request stays answered.
+// - A turn another writer settled (a person's Stop) is over here: its pending requests are
+//   cancelled, and text still streaming into it is dropped until the provider's end of that turn
+//   or the next `turn.open`. Its running tool calls are still the provider's: a close reported
+//   after the Stop lands as reported, and whatever is still running settles at the provider's
+//   `turn.end` for it (or the next `turn.open`, or `session.ended`).
+// - An event the sink refused changed nothing. Re-apply the same event to retry it (after
+//   `backpressure`); `failed` and `closed` are final.
+// - A provider item is (thread, id): the same id on another thread is another item. Text and
+//   full snapshots of one id are one row, and its close settles it for both.
+// - After `session.ended` every event is dropped.

Subject: [PATCH 102/167] feat(native-chat): record fresh sessions after failed
 restoration (#25747)

* feat(native-chat): record a fresh provider conversation that replaced one the agent could not restore

A chat whose saved conversation the agent cannot reopen can now continue in a
fresh one: the handle chain records the new conversation as a creation that
replaces the lost one (which, why, and when), keeping every earlier link.

Rows keep a shape older builds read: the stored chain starts at the latest
replacement and carries the earlier links inside it.

* refactor(native-chat): store a replaced conversation flat; refuse it where older builds read the row

Older builds only read Claude and Codex records, so the nested stored form
protected rows no replacement can reach while adding a cap mismatch after a
downgrade. Store the chain as held, refuse a replacement in a Claude or Codex
chain until one has a stored shape older builds read, and refuse a supersession
key on a replacement that names no creation in the chain.

* test(native-chat): prove replacement rows survive downgrade and re-upgrade

Subject: [PATCH 103/167] Wait for Codex's live composer before pasting linked
 issue drafts (#25779)

* Wait for Codex's live composer before pasting launch drafts

* Keep timed-out Codex draft delivery consumed across remounts

* Document the checked terminal fixtures used by the remount test

* Distinguish Codex's reserved footer row from early multiline input

* Complete transcript baselines and suppress hidden terminal strings

* Align watcher scan budget with linked-directory reconciliation

* Drop unused snapshots after main removed the readiness census

Subject: [PATCH 105/167] Fix truncated Unicode branch names in base ref search

Preserve complete branch selectors when Git truncates or disambiguates short names, and keep slash-named local branches separate from remote-tracking refs through worktree creation and reuse.

Keep native/SSH namespace boundaries and mixed-version client capability gates intact. Accept Git-valid dotted components and cover collisions with configured and orphan tracking refs.

Adapted from @nishino-tsukasa's #19540. Independently reviewed in seven adversarial rounds; 235 focused tests and 77 affected-Apple-Git tests pass, along with typecheck, quality checks, and the desktop build.

Correct the inherited file-explorer cache-scan expectation while retaining its exact constant-work bound.

Correct the inherited release-parser compatibility assertion to match the pinned test dependency; all 121 cross-version tests pass locally.

Fixes #19515

Subject: [PATCH 106/167] fix(codex): never write a Codex config.toml that
 Codex can't load, and approve both symlink spellings (#25741)

* fix(codex): never write a hook approval Codex cannot load, and approve both symlink spellings

- Refuse any hooks.state write into a Codex config.toml (upsert, move,
  remove, mirrored enabled state, SSH installer) that would turn a loadable
  file into one Codex cannot load; write nothing and surface the reason.
- Read approvals written as dotted keys or inline tables.
- Approve and remove Orca's ~/.codex hook under both the spelled and the
  resolved key when ~/.codex or HOME is a symlink; move user approvals
  under both keys.
- Stale runtime trust cleanup no longer keeps an unexpected key whose
  conflicting duplicate tables read as no hash.

* refactor(codex): pass every hooks.json spelling as one sourcePaths list

* fix(codex): sweep retired-hook approvals under every key spelling; read literal-string trusted_hash

Subject: [PATCH 108/167] Keep remote worktree creation from navigating paired
 clients (#25793)

* fix(workspaces): keep remote creation from navigating paired viewers

* fix(workspaces): revoke pending navigation after connection replacement

* fix(workspaces): provision when the host renderer is unavailable

* test: align navigation and cache-scan expectations with current behavior

* fix(workspaces): provision broadcast creates without a host renderer

 reply-schema fallback must never shape a param. Gate on the token instead, where the
 client decides what it is willing to do with an arm it does not know.
 
+## Worktree activation belongs to a viewer
+
+Worktree creation and activation default to the host desktop for host/CLI requests,
+and to the caller for paired desktop/web requests. Mobile creation still activates
+the host renderer to provision setup and default tabs. A headless host does not
+borrow a paired client's view. Catalog and session updates continue to reach every
+subscriber independently of navigation.
+Headless host/CLI creates provision their shells, setup, and default tabs on the
+execution host in the background, without depending on an observer to open them.
+The same fallback applies when an attached host renderer is unavailable or
+reloading, including explicit `all` requests that target the host; availability is
+checked after creation, rather than before its awaits.
+
+`activateWorktree` client events carry an optional `navigation` field. Only explicit
+`clients` or `all` requests publish these events; updated clients ignore events
+without that address, including implicit broadcasts from older hosts. This is an
+optional JSON field (Rule 1): older clients ignore it and still understand explicit
+activation. The new host's default publication changes deliberately remove implicit
+navigation for older clients too, rather than retaining the unwanted behavior.
+An older host cannot express explicit follow intent to an updated client, so that
+client must open the workspace itself.
+Accepted navigation is also fenced through repository/worktree discovery; bridge
+cleanup, reconnection, or re-pairing revokes any activation still awaiting a fetch.
+
+Older CLIs hardcode `navigation: 'all'` for `--activate` and `--run-hooks`. The host
+recognizes their `cliProvenanceRequest` and normalizes that automatic target to
+`host`. An API caller without the CLI marker can still explicitly request `clients`
+or `all`. Neither creation nor activation navigates remote clients by default.
+
+Coverage: `multi-client-navigation-isolation.integration.test.ts` exercises real
+paired WebSocket clients and host/headless creation, the renderer bridge tests
+exercise older unaddressed publications, and
+`paired-worktree-activation-isolation.spec.ts` checks a paired desktop remaining in
+a local workspace while its remote catalog updates.

Subject: [PATCH 109/167] fix(notifications): replay completion sounds reliably
 (#15940)

* fix(notifications): replay completion sounds reliably

The in-flight `isNotificationSoundPlaying` gate dropped every notification
sound that arrived while the previous one was still ringing, so bursts played
once. Drop the gate and restart the cached Audio instead, and reuse an entry a
concurrent call already cached for the same path so parallel first playbacks
share one Audio rather than revoking each other's blob URL.

Subject: [PATCH 110/167] Show a tool call you stopped as interrupted, not
 failed (#25181)

* Move the turn message ordinals and the turn-row revision to the neutral timeline folder

Pure moves so a shared timeline assembler can use them: Codex's message
ordinal counter becomes ProviderTurnMessageOrdinals and Claude's turn-row
revision becomes the provider-neutral agent-journal turn-row revision. Only
names and import paths change.

* Admit one provider event's writes as one transition, and let rows be found again after a restart

- A sink transition is admitted whole or not at all; its steps run back to
  back at their turn in the journal's write queue, and each resolver reads
  the fold with every earlier write landed. A resolver may also say where the
  row belongs (turn scope, provider reference), and the writer always hears
  how the transition landed. A resolved lifecycle batch chooses its
  settlement mutations from the fold at execution.
- New optional row field providerItemRef: the provider's own reference for
  the item a row is, written only where the row's identity cannot spell it
  (Codex keys messages by their place in the turn and renumbers its item ids
  on resume). Set by the creating write, kept by revisions, indexed by the
  journal fold, never read by clients. A downgrade test shows an older host
  and client render such rows unchanged.
- Provider timeline identity schemes (shared legacy arm, Codex) and the join
  index that resolves a provider item to its row from memory or the fold:
  ordinals and request incarnations are read back from the rows, so a
  restart or an evicted entry finds the original row instead of placing a
  new one.

* Recover message ordinals from the journal's highest place, and forget joins read from a replaced epoch

A fresh join index continued a turn's messages at the first free place, so a journal holding only a
later ordinal (an imported or removed earlier row) had its sequence back-filled. The place is now
one past the highest ordinal any row or echoed send holds there, read through a pure scheme reader.
The join caches also drop what they read when the journal's epoch is replaced.

* Spell the subagent thread's message slot without spreading an identity union

* Add a provider timeline grammar and a shared assembler that decides at its turn in the journal

Adapters translate their provider's dialect into a small grammar (turns,
items, streamed text, requests, context facts, session end/reset); one shared
assembler turns it into the journal rows every structured lane writes.

Each event is planned as one sink transition. Which row a write lands on,
whether a replay writes anything, and every change to what the assembler
knows (its ledger) are decided by the transition's resolvers at the event's
turn in the journal's write queue, against the fold as it stands then. A
forecast (the ledger plus admitted events still queued) only answers apply()
at once. So a refused event allocates nothing, a write the journal rejects
leaves no trace in memory, and a restart or evicted cache finds the same rows
again. Text and full snapshots of one provider item share one row and one
lifecycle; reset always flushes text and settles the old session from the
journal; the open-work budget is derived from what is actually open.

Codex migration contracts compare against the existing Codex translator,
including a restart mid-stream and a repeat that outlives the join cache.

* Fix the types and the exhaustive event switch CI reported for the assembler

* Let the journal decide stream lifetimes, request reuse, named sends and background work

A third review found two blockers with the earlier rounds' cause, a remembered interpretation
trusted after the journal moved on:

- A reused request id was judged by its earlier prompt's settled turn before asking which turn the
  new one lands in, so a real approval in a later turn was dropped. The target turn now decides:
  the old turn again is a replay; a different live turn opens the next prompt beside it.
- A text stream checked its row's turn only on its first write, and a turn's end released streams
  by the turn planning expected. Every write now checks the row, a turn's end stops the streams
  whose rows are in it, and turn status reads the journal first, so another writer's Stop wins.

Also: a message boundary drawn by an event the journal held as a replay no longer splits an
anonymous message; a send naming a turn not yet open waits for that turn; the budget charges a
stream's thread and turn strings and the turn caches are byte-bounded; the open turn ends when the
journal shows it settled; a turn's opener is read from the journal's row.

Background work is now Orca's existing background-task row instead of a tool call flagged
`outlivesTurn` (a flag remembered only in memory, so a restart failed the task). A turn's end
never settles that row, so it survives restarts; session end leaves one in flight unverifiable.
Three tests that opened a background tool call with `outlivesTurn` now open a background-task row
and keep their original expectations about which turn the row stays in.

* Type the unbound assembler helper's drain as the void it reports

* Bound the rows kept for a continued anonymous message and the stopped streams

A row kept for the anonymous stream that may continue it, and the marker that a stopped stream's
queued writes write nothing, lived in the live-stream map and were never removed when no stream
followed. They now live in their own bounded maps, so the live map holds open streams only.

* Read a tool call a stop or the session's end cut short as interrupted, not failed

A call still running when its turn was interrupted, when the provider child
was seen to exit, or that the provider cancelled now carries `endedAs:
'interrupted'` beside `state: 'failed'`. Every build that predates the field
keeps reading the call as the failure it always showed; this build reads both
through one shared reader and counts the call apart from failures in the run
header, without the error tint on its partial output.

The shared assembler, the restart settlement and the Codex lane settle a
running call through one rule: only a proven interruption cuts it short, so a
turn the provider completed around an unclosed call, or work the host lost
track of, still reads failed.

* Assert a completed Codex turn leaves its unclosed call plainly failed

* Assert an unverifiable restart settlement leaves its running call plainly failed

* Let a later death proof correct the calls an unverifiable settle closed

A settle with no proof of the child's death closed its running calls as plain failed, so a
proof written afterwards corrected the turn to interrupted but could not find the calls. The
call now keeps endedAs: 'unverifiable' beside its failed state, and the stale settle revises
exactly those calls whose owner the proof names. Older builds still read them as failed.

* Render a cut-short call's output on mobile, with and without proof

* Find the mobile result box by walking to its View, and type the unverified-ending block

* Walk to the mobile result box without a type assertion

* Keep the journal store under its line limit after the main merge

* Drop the provider item reference, join index and identity schemes from the transition PR

Nothing in production reaches the state they defended (an assembler that lost its memory while
its child keeps streaming the same turn), and the stored Codex id was positional. The legacy
identity scheme moves to the assembler PR with its first caller; the Codex scheme and any
persisted reference wait for Codex to move onto the assembler. The Codex ordinal counter goes
back to codex/, since no neutral code imports it.

* Write a resolved settlement in one transaction through enqueueRows

A settlement too large for one row now commits all its rows or none, through the journal's
existing all-or-nothing write, instead of a row-by-row writer. Every row is built before any
commits, so a settlement naming one item twice is refused before anything is written.

* Drop the transition's landing report; keep the turn-row write fire-and-forget

Nothing reads which steps of a transition wrote. A failed step fails the sink, leaving the
steps before it written; the header says so, and tests cover it plus a settlement whose second
row fails inside the transaction. writeAgentJournalTurnRow returns nothing again, as on main.

* Run a transition's steps as a prefix; drop the paced flag and resolved options

A failed step no longer lets the steps after it write: each step checks, at its own turn in the
journal's queue, whether the write handed over just ahead of it completed, using the queue's count
of completed write bodies (a promise would report the failure only after the next step ran). The
sink fails only once every step has had its turn. The item step's `paced` size bypass and the
resolver's replacement `options` are removed; nothing planned uses them.

* Rebuild the timeline assembler on one admission-order state

The assembler kept a second copy of its state (a forecast beside a ledger), hydrated
the open turn from the journal, and recognised replays, all to recover from losing its
memory while the provider child kept streaming. That never happens: one assembler lives
exactly as long as one child, and a new child is a new assembler in a new generation
whose events land after the dead-generation sweep.

- One state, changed only when the sink admits an event (minted keys included), so a
  refused event takes nothing.
- Every journal-dependent choice is made when the write runs, by keyed reads: a turn row
  is written only where none is, a stream checks its row's turn on every write, a running
  snapshot never lands in a settled turn or relights a settled tool, a request takes the
  first incarnation the journal holds no row for.
- Rows are found by spelling their ids (provider-timeline-rows.ts); no join cache.
- The identity scheme (legacy arm only) lives here with its first caller; requests are
  spelled in their acquisition generation, since JSON-RPC ids restart per process.
- Saved history goes in as `input.history` plus ordinary events with the provider's ids,
  into an empty journal; `session.reset` and every replay rule are gone.
- One terminal-body function (`terminalAgentJournalBody`) is shared with the
  dead-generation settlement.
- The test rig's restart now sweeps and starts a new generation, as production does.

* Cover new running work in a turn the sweep ended

* Run a transition's steps in one queued write that loops over them

The steps of one event now share one turn in the journal's write queue: a
loop writes each in its own transaction through the row writer's
synchronous writeRows (split out of enqueueRows) and stops at the first
throw. Prefix semantics and "nothing lands between the steps" now hold by
construction, so the completed-write counter on the queue, the step gate
and the allSettled barrier are gone; the queue is back to main's bytes.

* End a turn another writer settled the way the provider's end does

A person's Stop settled the open turn's row without a word to the assembler.
The assembler then forgot the turn: its running tools and pending prompts were
never settled, the provider's own end and withdrawal were dropped, and the
turn's text streams stayed counted against the open budget for the life of the
process. Text the provider kept streaming afterwards could land as a message
outside the stopped turn.

- The open turn the journal shows settled ends first, as one transition, through
  the same settlement the provider's turn.end plans; its streams stop and their
  keys drop later text until that turn's end or the next turn opens.
- turn.end and request.withdrawn are admitted for a turn or request the journal
  holds; their settlement writes nothing for rows already settled.
- The budget's re-check frees streams whose turn settled.
- A settled tool keeps its terminal body against any differing write.
- Session-end settlement of lost background work uses the journal's own
  lostLiveWorkJournalBody instead of a copy.
- The rig's window elapses before every read, and restart swaps and disposes
  the old assembler.

* Leave a stopped turn's running tools to the agent's own end

When another writer settles the open turn (a person's Stop), the assembler
now only stops that turn's text and cancels its pending prompts. Running tool
calls stay the agent's: a progress update or completion it reports after the
Stop lands as reported, and whatever is still running settles at the agent's
turn end for that turn, the next turn's open, or the session's end.

An agent's end for an earlier turn while a newer one is open no longer clears
the open turn's activity line or ends its anonymous reply. An unnamed end right
after a Stop ends the stopped turn instead of being dropped. The test rig's
restart no longer writes the dead assembler's window text, matching dispose.

* Pin that a stopped turn's running tools hold budget until the agent's end

* Type the stopped turn's tool progress update as a tool body

* List every event the assembler hands to the decision step

The type-aware lint requires an exhaustive switch with no default case.
Also retitle a Stop test to say what it asserts.

* End a running call as its turn's journal row ends

A call still running when its turn ends takes the state of that turn's
row: a row another writer settled first (a person's Stop) stands, so its
calls read interrupted whatever the provider's later end reports. The
no-ending path that settled calls from the Stop row is gone, since a Stop
now leaves running calls to the provider. Adds the two Spanish strings.

* Settle a stopped turn's running call as its turn row ended after a restart too

The restart sweep ended every running call by the death evidence alone, so after
a person's Stop with no proof the child died the call read failed under a turn
that read interrupted. The sweep and the live dead-generation settlement now ask
the same rule the assembler does: a call in a turn already settled ends as that
row ended; only a turn still running leaves its calls to the evidence.

* Keep the dead-generation settlement under the line cap

* refactor(native-chat): drop saved-history adoption from the timeline assembler

The common pattern discards the history a provider replays while loading a
session, so the assembler has no use for an input.history event.

* refactor(native-chat): a pending input is only Orca's send now

Review follow-up to the adoption removal: drop the comment naming the
provider's saved message, and make requestedAt required since every pending
input comes from input.accepted.

* test(ratchet): require src/main/provider-process now that it has landed

* test(native-chat): build this stack's journal identities with main's opaque provider handle

Main's #24991 replaced the {kind, ...} handle with {transport, agent, nativeId}; three test
files from this stack still wrote the old shape. Same lines the downstream ACP branch uses.

Subject: [PATCH 111/167] feat(native-chat): open structured chat's wire and
 stored records to registered agents, behind a negotiated capability (#25159)

* refactor(native-chat): keep the provider resume handle opaque to shared code

Shared structured-chat code parsed each provider's resume handle: Claude's
session id and branch leaf, Codex's thread id, through a 'claude' | 'codex'
union every new agent had to widen. The in-memory handle is now
{ transport, agent, nativeId, providerData? }: shared readers use nativeId,
lease and handle-chain checks compare transport and agent, and only the
Claude adapter reads its leaf (providerData).

Stored and wire forms are unchanged for Claude and Codex. One encoding
module writes their typed shapes and decodes both those and the neutral
shape a new transport uses, which an older build refuses as unreadable
rather than reading as Codex. Key and root strings, which fork seeds,
superseded creations and resume offers persist, stay byte-identical.

The journal's own handle type becomes the journal-row and attach-wire
encoding of the same handle, and the journal identity carries the
neutral handle (null before the provider proves one).

No user-visible change.

* fix(native-chat): derive journal-row provider handles from the journal identity

The journal row converter now takes the identity every caller already holds,
so a row's handle has one obvious constructor. Tests that wrote the in-memory
handle straight into journal rows now build it through that converter, and the
processless Claude fixture names a not-yet-proved handle as null.

* fix(native-chat): refuse a stored provider handle written in both forms

A typed Claude or Codex handle that also carries the neutral form's
transport, agent, native id or provider data named two identities; it
was read as Claude or Codex and the next write dropped the other one.
Such a row now stays unreadable and is set aside untouched.

* refactor(native-chat): route structured agents through registered definitions

The structured-chat shared layer named Claude and Codex in a closed router
type, in option reads, in frame classification, and in renderer label and
validation branches, so adding an agent meant editing shared types. Each
agent now has a definition (capabilities, resting option rules) owned by its
own module; the router is a registry of definition + adapter pairs built at
runtime setup, and shared code reads the definition instead of the name.

No behavior change for Claude or Codex; no wire or stored shape change.

* refactor(native-chat): name the structured agent list once in host types

The host types, conversation commands, provider-session ownership and the
runtime's create path spelled the structured agent list inline; they now use
the one shared type the record and wire already validate against.

* fix(native-chat): narrow the record before reading its agent's option rules

* refactor(native-chat): make the router's registrations the only agent definition lookup

The at-rest option reads looked definitions up in a second, separately populated map, so a
registered definition could route and declare capabilities while the static map decided which
options a chat at rest accepted. The router now answers `definition(agent)` from its
registrations, the at-rest readers take it through the host's adapter, and the built-in
definitions are listed only where the runtime composes the router.

* feat(native-chat): open the structured-chat wire and stored records to registered agents

A host's structured agents are the ones its runtime registered. Records, RPC
params, persisted tabs and the model catalog accept any registered agent instead
of naming Claude and Codex; each agent's definition declares the transport its
handles live in and the variable its account home pins. A new runtime
capability, agent-session.structured.registered-agents.v1, advertises that a
host accepts and lists its agents (agentSession.agents, with each agent's
capability record), and the host withholds any other agent's tabs and restart
offers from clients that do not advertise it.

* test(native-chat): cover registered agents on the wire, in storage and across versions

* refactor(native-chat): let the record store decide which agents' tabs exist

* test(native-chat): declare the pilot test agent's storage

* test(native-chat): read the old build's saved tabs through a parsed shape

* fix(native-chat): act on restart offers only for agents the calling client can show

A paired client too old to show an agent's chat was listed only the offers it could show, but
dismissing or continuing all reached every offer on the host, and a named continuation answered
with the host's whole remaining inventory. The client's audience now goes to the host with every
restart operation: only offers it sees are reserved, dismissed or returned. Without an audience
(this host's own process, or a client that shows every agent) nothing changes.

* test(native-chat): read an agent-registering baseline's storage on its own terms

The registered-agents downgrade test assumed its baseline release predates registered agents: it
expected the saved-tab parser to erase an unknown agent and called the record reader without the
agents list. Once a release with this change becomes the baseline, both break. The expectations now
follow what the baseline host advertises, and an agent-registering baseline is handed its own
Claude and Codex storage.

* refactor(native-chat): derive record-store admission from the runtime's agent registrations

Which agents a stored record may name and which agents the router drives came from two lists in
the runtime, so a newly registered agent could be routed while its records were set aside. One
list of registrations now holds each agent's definition and the factory for its adapter: the
store's admitted agents are derived from it before the store opens, and the adapters are built
from it once it has.

* fix(native-chat): hand the exit drain a promise for every registered agent

* fix(native-chat): let the adoption conflict check read any agent's ownership

Ownership rows name any registered agent since the stored records opened to them; the adoption
check compares by agent, so it takes the same open id. Only Claude and Codex still adopt.

* test(native-chat): use opaque handle in queued rejection fixture

* test(native-chat): share one Codex journal identity in the integration suite

Main grew the suite to the 800-line limit; the opaque-handle import pushed it
over. The two tests built the same identity inline.

* refactor(agent-session): name the handle's adapter state resumeCursor

Rename the neutral provider handle's providerData to resumeCursor before any
row persists the neutral form: it is an adapter-owned resume position (Claude's
transcript leaf), never identity. Claude/Codex stored and wire bytes are
unchanged; their typed shapes never carried the field.

State the stored-form contract (a handle's field set is closed; later per-link
data goes on the chain link, which every build preserves) and pin it with a
record round-trip test. Document that transport records the id space the
native id was minted in, which can differ from the agent's current transport.

* refactor(agent-session): one required agent registry; declarations admit what they claim

A StructuredAgentRegistry, built once from the {definition, adapter}
registrations, is now a required host dependency and the router routes with
it. The adapter interface loses its optional router-only capabilities?() and
definition?(); every reader (options at rest, thread goal, rewind, the
/compact handover) asks the registry. A live session still narrows rewind
through the adapter, and the host combines declared and narrowed in one
helper. The registry refuses a registration that declares compact, a thread
goal or rewind without the adapter method behind it.

/compact is admitted by the declared capability, so an agent that declares
compact:false gets the commandRefused fact instead of a thrown error.

Also: the cut-turn notice names the agent from the catalog, create-support
builds the account home through agentSessionAccountHome, and the turn
status text older clients read names the session's agent instead of
defaulting to Codex (Claude/Codex text unchanged).

* refactor(agent-session): the router applies the declared rewind itself

The router holds the registry, so its rewindSupport answers the owner's
declared rewind narrowed by the adapter, in one place no reader can bypass.
The host-side combining helper is gone; readers ask the adapter they hold.

* test(agent-session): register the agents the merged-in tests now need

The adoption replay test builds its host over this build's registered agents
instead of an adapter definition method, and the stored-form test passes the
stored agents the record guard now requires.

* chore(agent-session): the registry is the one lookup; drop the test-only empty capability record

* fix(agent-session): keep "dismiss all" restart offers dismissed for the desktop

The desktop renderer calls the restart methods as a paired runtime client
without the registered-agents capability, so it was handed a Claude/Codex
audience and its "dismiss all" took the scoped path: no dismissal fence and
no clearing of unwritten teardown witnesses, so a late teardown write could
bring a dismissed offer back.

The audience is now derived against this host's registry: a client that can
show every agent the host registered gets none, and dismisses exactly as
before (one fence for every offer). A client that truly cannot show some
agent still gets a final dismissal for what it sees: each cleared session is
fenced on its own (bounded, superseded by a dismiss-all fence) and only the
witnesses of agents it sees are dropped.

One predicate now answers which agents a client renders, for both tab
projection and restart offers; the Claude capability rule is folded in.

* fix(agent-session): a changed agent definition never hides that agent's chats

A record was readable only if every handle used the transport its agent's
definition declares today, and its account variable was declared by some
registered agent. A later build that drives the same agent over another
protocol, or under a renamed variable, would have set every existing chat of
that agent aside: no tab, no history, no error.

Readability now asks only that the record agree with itself: its agent is
registered, every handle shares one namespace owned by that agent, and the
account variable is a well-formed name. Whether this build can drive it (the
chain's transport is the one the agent speaks, and the account variable is
that agent's own, since it becomes the child's environment) is decided in
performAttach, the one admission every start of every agent passes through,
and refused there as hostUnsupported. A record pinning another agent's
variable is refused the same way rather than passing because some agent
declares it.

* refactor(agent-session): each agent's registration says where it runs and which account it pins

createSupport, create and the model catalog's account read still chose a
location rule and an account resolver by name (Claude, Codex, else none),
so a new agent would have needed a third branch beside the registration
list that already decides storage, routing and publication.

Each runtime registration now carries supportsLocation(location) and
resolveAccountHomePath({ launchEnv, location, purpose, workspacePath }),
and Claude's and Codex's rules move into their entries unchanged: a read
still syncs no home and starts no bridge, a Codex launch still trusts the
workspace first, and WSL locations resolve as before. The list exists
before the host is built, so none of these reads installs the host, and an
agent the list does not hold is answered no without opening the journal.

* test(agent-session): drop a duplicate registry key; keep fences out of the capsule state

A spread input already carries the registry, so the explicit key was
overwritten (TS2783). The session-fence helper now returns only the fence,
not the capsule state it was given.

* fix(agent-session): a scoped dismiss-all persists no per-session fence

The per-session dismissal fence added a forever-persisted capsule field
with an arbitrary cap that served no caller: only the local desktop calls
the restart methods, and on a host whose agents it all shows it gets no
audience and takes the unscoped, fenced dismissal. A scoped dismiss-all
(a caller that cannot show some registered agent) keeps that agent's
offers, clears only its audience's unwritten witnesses, and writes no
fence; a late write from this process is serialized behind it. The field
never left this unreleased branch.

* fix(agent-session): refuse an attach whose agent is not the session's own

The start check judges the record's agent while the router starts the adapter of params.agent, and the attach wire let the two differ. Admission now refuses agent !== provider as requestMalformed, so the agent checked is the agent started. Every host-built attach already sets them equal.

* fix(agent-session): offer to start a chat only when the start would accept it

The restart offer, a failure's retryable flag and the pre-send check asked only whether the adapter runs the chat's location, while the start also refuses a record this build cannot drive; such a chat was offered Resume and its Retry failed forever. One host predicate, hostCanStartRecord (location support and agentDrivesSession), now answers all four; adapterSupportsRecord stays the reader gate, and an undrivable chat's offer is kept, not retired.

* fix(agent-session): the model-catalog probe uses a record's account only if this build drives it

A record-scoped catalog read started the agent's lister under the record's account path whatever variable the record pinned. It now uses that path only when agentDrivesSession holds, and otherwise resolves the account as for a read with no record.

* refactor(agent-session): the record store admits agent ids; comments say where transport is checked

The store only ever asked whether an agent is registered, so its admission list is now the registered ids; the definition is the one home of an agent's transport and account variable. Comments that said the record store checks transport, and one that cited a nonexistent function, now point at agentDrivesSession and the attach admission. The isPersistedAgentSessionRecord(value, agents) call shape and the test fixture the cross-version probe imports are kept.

* docs(agent-session): the record store admits the registered agents' ids

* test(native-chat): dismiss-all through a remote client's audience keeps a newer Orca's offer

Uses an audience production sends (one that cannot show every agent), per review.

* chore(native-chat): keep the record store and recovery capsule under max-lines after the main merge

* test(native-chat): build the Stop-opened-turn test's identity and turn context the current way

The test (#25056) landed before the opaque provider handle (#24991), so main still built
the old {kind, threadId} handle; the turn context also needs this branch's agent registry.

* test(ratchet): require src/main/provider-process now that it has landed

* test(native-chat): keep main's opaque-handle import in the Stop-opened-turn test

Main's #25706 and this branch both added the import at different lines; the merge kept both.

* Keep saved chats readable without provider registration

* Keep stored-record compatibility checks independent of registration

* Keep saved providers in restart client audiences

* test(native-chat): type reveal fixtures without assertions

* test(wire): expose known agents in structured host fixture

* Supply startability dependency in the new Codex catalog fixture

Subject: [PATCH 112/167] Refresh visible reviews automatically and stop
 settled merged polling (#25788)

Refresh only actual on-screen review cards and the selected visible review panel, with a single metadata owner per execution host. Open reviews refresh every 60 seconds when selected and 120 seconds otherwise. Settled merged reviews stop automatic refresh; pending merged checks continue, hidden rows stop, and work changes or stale re-exposure discover fresh state.

Remove the polling setting. Preserve provider/SSH/runtime ownership, mixed-version cache behavior, failure backoff, bounded foreground admission, request coalescing, and mutation invalidation. Cover older persisted caches and unknown HEADs.

Validated with 1,628 focused tests, typechecking, lint/code-quality gates, hidden Electron viewport checks, and parallel Codex/Claude Opus 5.5 adversarial reviews. Measurements and policy details are in PR #25788.

Fixes #25746

Subject: [PATCH 114/167] Fix premature Claude automation completion and
 inherited CI failures (#24878)

* fix(agent-status): keep a Claude pane working until owed task wake-ups arrive

Claude wakes the main agent for each background task that ends, after the
task stops running. "Nothing running" was read as done, so automations
closed the terminal before the final turn.

Fixes #23942

* fix(agent-status): keep owed task wake-ups through failed turns, the cap and nested exits

A failed turn's task list now marks a vanished shell owed like a normal turn end does. Past
the cap only an already-announced sub-agent is forgotten. A process exit clears what is owed
only where the server admits it from the pane's owner.

* refactor(agent-status): move pane-scoped cache entry helpers out of listener-state

listener-state.ts passed the 300-line limit once main's and this branch's additions met.

* fix(agent-status): verify Claude task wake-up completion on its execution host

* fix(agent-status): canonicalize Claude background task identifiers

* Preserve out-of-order Claude task notification evidence

* Verify retained released parser in cross-version checkout test

* Reuse watcher directory-cache enumeration without losing fresh keys

Subject: [PATCH 117/167] Translate ACP traffic into shared timeline events
 (#25090)

* Add standalone ACP protocol client and session runtime

* Protect ACP transport teardown from late stream errors

* Retire incoming ACP request ids before publishing responses

* Narrow ACP configuration requests and transport message types

* Remove redundant ACP request handler return unions

* Keep ACP waits caller-owned and preserve protocol extensions

* Preserve open ACP decisions through prompt completion

* Move the turn message ordinals and the turn-row revision to the neutral timeline folder

Pure moves so a shared timeline assembler can use them: Codex's message
ordinal counter becomes ProviderTurnMessageOrdinals and Claude's turn-row
revision becomes the provider-neutral agent-journal turn-row revision. Only
names and import paths change.

* Admit one provider event's writes as one transition, and let rows be found again after a restart

- A sink transition is admitted whole or not at all; its steps run back to
  back at their turn in the journal's write queue, and each resolver reads
  the fold with every earlier write landed. A resolver may also say where the
  row belongs (turn scope, provider reference), and the writer always hears
  how the transition landed. A resolved lifecycle batch chooses its
  settlement mutations from the fold at execution.
- New optional row field providerItemRef: the provider's own reference for
  the item a row is, written only where the row's identity cannot spell it
  (Codex keys messages by their place in the turn and renumbers its item ids
  on resume). Set by the creating write, kept by revisions, indexed by the
  journal fold, never read by clients. A downgrade test shows an older host
  and client render such rows unchanged.
- Provider timeline identity schemes (shared legacy arm, Codex) and the join
  index that resolves a provider item to its row from memory or the fold:
  ordinals and request incarnations are read back from the rows, so a
  restart or an evicted entry finds the original row instead of placing a
  new one.

* Recover message ordinals from the journal's highest place, and forget joins read from a replaced epoch

A fresh join index continued a turn's messages at the first free place, so a journal holding only a
later ordinal (an imported or removed earlier row) had its sequence back-filled. The place is now
one past the highest ordinal any row or echoed send holds there, read through a pure scheme reader.
The join caches also drop what they read when the journal's epoch is replaced.

* Spell the subagent thread's message slot without spreading an identity union

* Add a provider timeline grammar and a shared assembler that decides at its turn in the journal

Adapters translate their provider's dialect into a small grammar (turns,
items, streamed text, requests, context facts, session end/reset); one shared
assembler turns it into the journal rows every structured lane writes.

Each event is planned as one sink transition. Which row a write lands on,
whether a replay writes anything, and every change to what the assembler
knows (its ledger) are decided by the transition's resolvers at the event's
turn in the journal's write queue, against the fold as it stands then. A
forecast (the ledger plus admitted events still queued) only answers apply()
at once. So a refused event allocates nothing, a write the journal rejects
leaves no trace in memory, and a restart or evicted cache finds the same rows
again. Text and full snapshots of one provider item share one row and one
lifecycle; reset always flushes text and settles the old session from the
journal; the open-work budget is derived from what is actually open.

Codex migration contracts compare against the existing Codex translator,
including a restart mid-stream and a repeat that outlives the join cache.

* Fix the types and the exhaustive event switch CI reported for the assembler

* Let the journal decide stream lifetimes, request reuse, named sends and background work

A third review found two blockers with the earlier rounds' cause, a remembered interpretation
trusted after the journal moved on:

- A reused request id was judged by its earlier prompt's settled turn before asking which turn the
  new one lands in, so a real approval in a later turn was dropped. The target turn now decides:
  the old turn again is a replay; a different live turn opens the next prompt beside it.
- A text stream checked its row's turn only on its first write, and a turn's end released streams
  by the turn planning expected. Every write now checks the row, a turn's end stops the streams
  whose rows are in it, and turn status reads the journal first, so another writer's Stop wins.

Also: a message boundary drawn by an event the journal held as a replay no longer splits an
anonymous message; a send naming a turn not yet open waits for that turn; the budget charges a
stream's thread and turn strings and the turn caches are byte-bounded; the open turn ends when the
journal shows it settled; a turn's opener is read from the journal's row.

Background work is now Orca's existing background-task row instead of a tool call flagged
`outlivesTurn` (a flag remembered only in memory, so a restart failed the task). A turn's end
never settles that row, so it survives restarts; session end leaves one in flight unverifiable.
Three tests that opened a background tool call with `outlivesTurn` now open a background-task row
and keep their original expectations about which turn the row stays in.

* Type the unbound assembler helper's drain as the void it reports

* Bound the rows kept for a continued anonymous message and the stopped streams

A row kept for the anonymous stream that may continue it, and the marker that a stopped stream's
queued writes write nothing, lived in the live-stream map and were never removed when no stream
followed. They now live in their own bounded maps, so the live map holds open streams only.

* Translate ACP session traffic into shared timeline events

* Preserve fixture answer linkage and handle all typed ACP updates

* Keep replay chunks and long-turn tool snapshots bounded

* Forward ACP joins to the journal-derived timeline assembler

* Use exact ACP prompt identity and recover incomplete timeline replay

* Detect short and Unicode home paths in encoded ACP fixtures

* Use generic privacy patterns for ACP fixtures

* Translate Grok background work into durable task rows

* Recover background task origin from its persisted launch tool

* Restate background task fallback from its terminal evidence

* Require session identity on Grok task notifications

* Honor explicit Grok task completion without an exit code

* Match the background reset test to the final timeline grammar

* Give task completion fixtures a specific evidence type

* Settle ACP background tasks from live and replayed evidence

* Honor background task outcomes carried by replayed tool results

* Keep the journal store under its line limit after the main merge

* Drop the provider item reference, join index and identity schemes from the transition PR

Nothing in production reaches the state they defended (an assembler that lost its memory while
its child keeps streaming the same turn), and the stored Codex id was positional. The legacy
identity scheme moves to the assembler PR with its first caller; the Codex scheme and any
persisted reference wait for Codex to move onto the assembler. The Codex ordinal counter goes
back to codex/, since no neutral code imports it.

* Write a resolved settlement in one transaction through enqueueRows

A settlement too large for one row now commits all its rows or none, through the journal's
existing all-or-nothing write, instead of a row-by-row writer. Every row is built before any
commits, so a settlement naming one item twice is refused before anything is written.

* Drop the transition's landing report; keep the turn-row write fire-and-forget

Nothing reads which steps of a transition wrote. A failed step fails the sink, leaving the
steps before it written; the header says so, and tests cover it plus a settlement whose second
row fails inside the transaction. writeAgentJournalTurnRow returns nothing again, as on main.

* Generate open ACP enums and check the generated schema offline

A newer or vendor enum value (tool kind, tool status, option kind, stop
reason) no longer fails the whole message: generated enums accept the known
literals plus any other string, typed so callers can still narrow on the
known ones. The generated header now records the pinned input digests, the
generator digest and a body hash, so `verify:acp-protocol` catches a stale or
hand-edited file without network access; it runs in lint and the PR workflow.

* Land the ACP runtime contract the agent adapters use

- Deliver notifications other than session/update through
  onExtensionNotification, in arrival order with session updates.
- Accept _meta on prompt, setMode, setModel, setConfigOption and cancel.
- cancel() always sends session/cancel once the session runs, since the
  agent can be in a turn it began itself; only a successful send is shared,
  so a failed write is retried.
- Cancel aborts each open agent request's signal and lets its handler send
  its own answer; -32800 only when the handler rejects.
- Permission requests validate only the session, tool call id and options;
  unreadable fields are dropped with a diagnostic, and any answer Orca
  cannot send is `cancelled` instead of a JSON-RPC error. Agent-started
  turns may ask; whether to show it is the caller's decision.
- AcpAgentError marks the agent's own errors; AcpInvalidResponseError keeps
  the raw answer and validation issues for answers Orca could not read.
- Lines over the size limit are classified by prefix (shared with the Codex
  reader): the owed request fails, an oversized agent request is answered
  with an error, and an unattributable response closes the connection.

* Run a transition's steps as a prefix; drop the paced flag and resolved options

A failed step no longer lets the steps after it write: each step checks, at its own turn in the
journal's queue, whether the write handed over just ahead of it completed, using the queue's count
of completed write bodies (a promise would report the failure only after the next step ran). The
sink fails only once every step has had its turn. The item step's `paced` size bypass and the
resolver's replacement `options` are removed; nothing planned uses them.

* Rebuild the timeline assembler on one admission-order state

The assembler kept a second copy of its state (a forecast beside a ledger), hydrated
the open turn from the journal, and recognised replays, all to recover from losing its
memory while the provider child kept streaming. That never happens: one assembler lives
exactly as long as one child, and a new child is a new assembler in a new generation
whose events land after the dead-generation sweep.

- One state, changed only when the sink admits an event (minted keys included), so a
  refused event takes nothing.
- Every journal-dependent choice is made when the write runs, by keyed reads: a turn row
  is written only where none is, a stream checks its row's turn on every write, a running
  snapshot never lands in a settled turn or relights a settled tool, a request takes the
  first incarnation the journal holds no row for.
- Rows are found by spelling their ids (provider-timeline-rows.ts); no join cache.
- The identity scheme (legacy arm only) lives here with its first caller; requests are
  spelled in their acquisition generation, since JSON-RPC ids restart per process.
- Saved history goes in as `input.history` plus ordinary events with the provider's ids,
  into an empty journal; `session.reset` and every replay rule are gone.
- One terminal-body function (`terminalAgentJournalBody`) is shared with the
  dead-generation settlement.
- The test rig's restart now sweeps and starts a new generation, as production does.

* Answer every agent request after an ACP cancel

A cancel that lands before a permission handler starts now still runs the
permission path, so the agent gets the `cancelled` outcome rather than a
request-cancelled error. A handler that ignores the abort no longer leaves
the agent waiting: once the abort has run through, any request still
unanswered gets request-cancelled. Handlers that answer on abort keep their
own reply.

Also renames a lint-rejected helper parameter, replaces a Reflect.apply in a
test, and stops the permission diagnostic from firing with an empty list.

* Cover new running work in a turn the sweep ended

* Run a transition's steps in one queued write that loops over them

The steps of one event now share one turn in the journal's write queue: a
loop writes each in its own transaction through the row writer's
synchronous writeRows (split out of enqueueRows) and stops at the first
throw. Prefix semantics and "nothing lands between the steps" now hold by
construction, so the completed-write counter on the queue, the step gate
and the allSettled barrier are gone; the queue is back to main's bytes.

* Let each ACP request handler own its answer after a cancel

Removes the next-event-loop-turn fallback that answered request-cancelled
for any handler still silent after a cancel. It raced answers that were
still being saved (an approval mid-journal-write reached the agent as an
error) and made the outcome depend on event-loop timing. The handler that
owns an agent request now always sends its answer, or throws for
request-cancelled; a request it never answers ends when the connection
closes. A permission whose handler had not started still answers
`cancelled`.

* End a turn another writer settled the way the provider's end does

A person's Stop settled the open turn's row without a word to the assembler.
The assembler then forgot the turn: its running tools and pending prompts were
never settled, the provider's own end and withdrawal were dropped, and the
turn's text streams stayed counted against the open budget for the life of the
process. Text the provider kept streaming afterwards could land as a message
outside the stopped turn.

- The open turn the journal shows settled ends first, as one transition, through
  the same settlement the provider's turn.end plans; its streams stop and their
  keys drop later text until that turn's end or the next turn opens.
- turn.end and request.withdrawn are admitted for a turn or request the journal
  holds; their settlement writes nothing for rows already settled.
- The budget's re-check frees streams whose turn settled.
- A settled tool keeps its terminal body against any differing write.
- Session-end settlement of lost background work uses the journal's own
  lostLiveWorkJournalBody instead of a copy.
- The rig's window elapses before every read, and restart swaps and disposes
  the old assembler.

* Adopt ACP load history only into an empty journal, chosen by the translator's creator

The translator now takes `adopt` from whoever creates it instead of guessing from the
journal (which reads empty before the sink binds). Without adoption, history a provider
replays during session/load is dropped except its context usage. With adoption, history
becomes ordinary events with provider or position ids and the user's saved messages become
`input.history`, so re-running an interrupted adoption lands the same rows.

The translator no longer reads the journal: it lives exactly as long as its provider child.
Its tool snapshots are bounded by the assembler's open budget, and a small record of each
tool's turn keeps a late background-task notice beside the tool that started it.

* Leave a stopped turn's running tools to the agent's own end

When another writer settles the open turn (a person's Stop), the assembler
now only stops that turn's text and cancels its pending prompts. Running tool
calls stay the agent's: a progress update or completion it reports after the
Stop lands as reported, and whatever is still running settles at the agent's
turn end for that turn, the next turn's open, or the session's end.

An agent's end for an earlier turn while a newer one is open no longer clears
the open turn's activity line or ends its anonymous reply. An unnamed end right
after a Stop ends the stopped turn instead of being dropped. The test rig's
restart no longer writes the dead assembler's window text, matching dispose.

* Pin that a stopped turn's running tools hold budget until the agent's end

* Type the stopped turn's tool progress update as a tool body

* List every event the assembler hands to the decision step

The type-aware lint requires an exhaustive switch with no default case.
Also retitle a Stop test to say what it asserts.

* Say why a Grok turn failed, and keep task rows in Grok's own words

A failed Grok turn ended with no reason on screen: the translator dropped
every copy of Grok's message. The failed turn now gets one status row in
Orca's existing "provider did not accept this message" words with Grok's
reason, read from whichever copy arrives first (the given-up retry, the
turn's end, the prompt's completion notice, or the prompt's error answer);
later copies only fill a reason the row still lacks.

A running background command no longer reads "Background task <id>
started": a task's summary is mapped only once it has settled. A monitor
stays a monitor when the agent reads its output: a frame that names no
kind keeps the known one, and a "[monitor" command is a monitor.

A prompt's turn is marked started, so a late frame for an ended prompt
neither reopens it nor becomes the active turn. A tool's turn is held in
one place at a time.

* Read a monitor from Grok's exact output prefix

* Word a failed Grok turn in Grok's own text, not as a refused message

A turn that started and then failed was told "The provider did not accept
this message", Orca's sentence for a message refused before its turn. The
row now reads as a Codex turn-ending error does: an error status row with the
provider's own words. With no words, the dialect names the failure ("Grok
ended this turn with an error." / "Grok usage limit reached."), else the
agent's display name does.

* Register the ACP schema verify step in the PR preflight phase test

* Read ACP permissions, session events and prompt errors through the protocol client's own types

The translator now reads a permission request with the client's lenient reader, a session update
with its session-event reader, and takes only the agent's own error answer as a failed prompt's
reason, so an Orca-side error never reads as the provider's words. Tests cover protocol values
newer than this build.

* refactor(native-chat): drop saved-history adoption from the timeline assembler

The common pattern discards the history a provider replays while loading a
session, so the assembler has no use for an input.history event.

* refactor(acp): drop session/load history adoption from the translator

The common pattern discards the history an agent replays during session/load,
keeping only what it says about the context window. Remove the adoption path
(acp-history-adoption.ts, the adopt option, and the historical background-task
liveness rewrite it fed) so load replay is always dropped except usage.

* refactor(native-chat): a pending input is only Orca's send now

Review follow-up to the adoption removal: drop the comment naming the
provider's saved message, and make requestedAt required since every pending
input comes from input.accepted.

* test(acp): keep the task-result status table on live frames

Review follow-up to the adoption removal: the result-status mapping was only
tested through adopted history, so run the same table on live frames, and
cover an unmarked task notice during a load being dropped.

* Use current provider handles in transition tests

* Use current provider handles in timeline fixtures

* Require the ACP directory in the runtime import check

Subject: [PATCH 118/167] fix(native-chat): a chat you return to drops
 background tasks that finished while it was hidden (#24305)

* fix(native-chat): a chat you return to drops background tasks that finished while it was hidden

A background command that finished while its chat pane was hidden stayed in
the strip as running, its timer counting for hours, and Stop failed with "The
background task wasn't stopped." The pane stops listening while hidden, so it
missed the "no tasks" update; once the idle sweep stopped the agent, the host
reopened the pane's subscription without any roster at all, and the client
reads a missing roster as "unchanged".

The roster now rides each subscriber's frames the way the slash-command list
and the message queue already do. The subscriber registry reads it from the
host's child records on a subscriber's first frame and on every snapshot and
reset, and re-sends it to each subscriber whose last copy differs when the
records change. The channel always answers: a conversation with no running
child is "none" whether or not an agent holds it. Ordinary journal batches
never read it.

This also fixes the reverse case: a snapshot or reset sent to a live pane
carried no roster, which cleared a still-running task from the strip until the
roster next changed.

The client treats a resumed subscription's first batch as stating the roster,
so a pane reconnecting to an older host that still omits it drops its stale
copy too.

Fixes #24227

* refactor(native-chat): require the background-task roster read and drop the unused close observers

The host's delivery layer now requires every hook it is built with, so
production wiring cannot leave out the roster read (an opening frame
without it reads as "no tasks" to current clients). The conversations
map's close observers lost their only caller in this PR and are removed.
The reducer test comment states the old-host omission rule precisely.

* refactor(native-chat): keep structured-agent-session-host.ts within the line limit

Main brought the host file to the 300-line lint limit, and this PR's
roster wiring adds one line. Name the lease reconciler's type by its
factory, as the neighbouring fields do.

* test(native-chat): build the roster test's Claude provider handle with claudeProviderHandle

Main made the provider handle opaque (#24991); build it with the existing
helper, as main's own tests now do.

Subject: [PATCH 121/167] Add confirmed conversation rewind from structured
 chat messages (#19338)

* feat(native-chat): confirm destructive conversation rewind from user messages

* fix(native-chat): retain rewind uncertainty from host status

* fix(native-chat): await the authoritative rewind epoch reset

* Pause restored chat outbox during rewind recovery

* Verify rewind targets after message acceptance

* test(native-chat): verify rewind copy against host reason contract

* fix: type rewind hook test props explicitly

* Show rewind explanations on keyboard focus

* fix(native-chat): read renamed background stop-all capability

* fix(native-chat): consolidate epoch test vitest imports

* fix(native-chat): restore rewind refusal delivery after merge

* fix(native-chat): satisfy main's design-system and cast gates in rewind

Match the rewind button to the copy button beside it instead of
restyling the shared Button, read refusal reasons without a cast, and
merge a duplicate import.

* fix(native-chat): let the host govern an in-doubt rewind; offer Edit from here only on turn openers

- Pending starts after Confirm and ends with the request; a confirmed rewind waits up to 120 s
  for its new conversation, then lets go with one toast.
- An unknown outcome no longer blocks sending: the host recovers it on the next send. Its latch
  only disables the action. The message goes back to the composer on success and on an unknown
  outcome; refusals and timeouts are toasted once instead of holding the error line.
- The action is offered only on sent prompts that opened their own turn (no steers, unsent,
  queued, /compact or goal rows), and not at all where the provider cannot rewind.
- Rewind is held behind host-queued cards, gets the command's 195 s remote timeout, focuses the
  composer after returning the message, drops the message count, and uses plain copy.

* fix(native-chat): say why a send waits while a rewind is in flight

* fix(native-chat): settle an in-doubt rewind on the next send, even with the agent running

- Host: a send (or /clear, /compact) that finds a rewind in doubt with the agent already running
  now runs the same provider recovery an attach would. Proven: the conversation is replaced and
  the send proceeds; proven not done: the record is refused and the send proceeds; still unknown:
  the send is refused as before, but before the ledger records it, so a Retry of the same id is
  decided afresh instead of replaying the refusal for a day.
- Client: a confirmed rewind whose pane was hidden during the wait lets go silently (a hidden pane
  reads nothing); the timeout and busy copy say what happened and what is needed.

* fix(native-chat): keep /clear's settled refusal while a rewind is in doubt; type the live-send test fixture

* test(native-chat): give the live-send rewind host the declared agents main now requires

* fix(native-chat): offer Edit from here only where the next send settles a rewind, and never on URL images

- New runtime capability agent-session.rewind-send-recovery.v1, advertised by this host: the
  rewind UI hands an in-doubt prompt back for the next send to settle, which hosts with only the
  rewind RPC refuse while the agent runs. The action is hidden until the host (local or remote)
  advertises it, and while that is unknown.
- A prompt with an image that has no local file is not offered: the image could not go back to
  the composer after the rewind discards it.
- Row and provider eligibility move to native-chat-rewind-eligibility.ts.

* fix(native-chat): keep when each kept message was first seen across a rewind

A rewind rebuilt the provider's kept items with the rewind's own time, so every kept message
showed the rewind time. The merge already carried a held row's scope and producer onto the
provider item; it now carries its first-seen time too, for the rewind and its recovery alike.

* fix(native-chat): hand rows the rewind through context so the list and pane stay within their line budgets after main's appearance changes

* fix(native-chat): fit the rewind recovery capability within protocol-version's line budget; hoist a test context value

* fix(native-chat): label the action "Rewind to here"

Subject: [PATCH 123/167] Run Vitest on Bun with Node runtime contracts
 (#25840)

* Run Vitest on Bun while preserving Node runtime contracts

* Preserve runtime timing provenance and keep the Bun pin in config

* Scope builtin compatibility mocks to test-only lint exceptions

* Give capture retention fixtures distinct filesystem timestamps

* Await the copy button success state in the React fixture

* Bound Node test worker shutdown and tighten migration fixtures

 ## Local Setup
 
+Install Node 24, pnpm, and the Bun version in [`config/bun-version`](../config/bun-version).
+`pnpm test` runs Vitest on Bun, with Node workers for runtime contracts such as SQLite,
+native PTYs, socket liveness, and V8 memory behavior. `pnpm test:node` runs the same suites
+entirely on Node. Builds and dependency installation still use Node and pnpm.
+
 ```bash
 pnpm install
 pnpm dev

Subject: [PATCH 125/167] fix(native-chat): keep a message accepted before a
 quit or crash as a held card (#24660)

* fix(native-chat): keep a message accepted before a quit or crash as a held card

A send the host accepted while the agent was still starting, and never handed
over, was rejected unseen at quit or at the next open after a crash. The next
open now keeps a person's message (typed, or a launch's first prompt) as a
waiting card at the head of the queue, held until Resume, Send now, Edit or
Delete; quit no longer rejects it. Each submission records its source so a
restart knows which leftovers to keep. A direct send's replay answers from its
own record, never the queued arm. Cards shown without the queue capability
hide Turn off queueing and the steer chord.

* fix(native-chat): keep an unsent message as a held card at every close, not only a restart

The host now keeps a person's message it accepted and never handed over with one
rule wherever it can no longer hand it over: a quit or crash (settled at the next
open) and a close of the chat (tab close, worktree teardown, orchestration stop).

- The hold is card state: a new per-card hold_reason 'kept', published as the
  existing pausedReason, instead of a fake host_instance value. host_instance
  means the owner again, and the pause clause, adoption filter and /clear carry
  special cases are gone. A kept card holds the cards behind it until the
  person sends, edits or deletes it; a send_failed card still does not.
- A card hand-off rejected by a restart or a close returns as a kept card
  (rejectedDraftSettlement), so a person's next message can never release it.
- One hold function, parameterized by cause (hostRestarted / chatClosed),
  replaces the close path's plain rejection.
- The phone shows published cards and per-card holds whatever the queue
  capability says; only queueing a new send stays gated.
- source gains 'dispatch' for the orchestration preamble (still rejected); an
  unknown source is kept as written and never takes the legacy rule.
- Kept cards from earlier settlements stay ahead of a batch's new ones.

* test(native-chat): the dispatch preamble records its source

* fix(native-chat): skip a kept card like a failed one, and make a quit leave the queue as a crash does

- A kept card is held on its own, as a send_failed one is: the queue sends the
  cards behind it, and the "a message ahead needs attention" caption no longer
  appears behind it (desktop and phone).
- Quit disposes the queue's drain together with delivery, so it mints no
  hand-off that only the next process could settle.
- Only a Send the person asked for (origin client) that a restart or close cut
  short returns kept; the queue's own hand-off returns where it stood, under the
  restart's pause, as on main.
- Comments that said only a capable host gets cards or the card actions now say
  the capability gates only queueing a new send.

* refactor(native-chat): one dispose gate in the queue drain's step

* test(native-chat): the downgrade test names the older build's /clear exception

* fix(native-chat): re-check the drain's quit gate right before it appends a hand-off

A drain step already past its first check when quit begins no longer makes a
hand-off. Adds regression tests for that, for Send now on an ordinary card cut
short by a quit, and for the open-time repair deriving kept from the hand-off's
origin; fixes the pause and settlement comments that called a kept card one the
queue never passes.

* fix(native-chat): a card held on its own starts no restart pause for the others

After a second restart a kept (or send_failed) card is another process's, but it
waits for its own Send, so it no longer pauses every other card under
"Queue paused because Orca restarted".

* fix(native-chat): record on a kept send which card holds it, so no trace survives an Edit or Delete

The rejection row of a send the host kept as a card now names that card
(`keptAsQueuedMessageId`), in the same transaction that writes the card, and the
fold publishes it on the submission. The shared projection draws such a send
only as its card: once the card is sent, edited or deleted, neither the send
nor the sending desktop's local copy of it shows.

* chore(native-chat): leave the unused submission schema as main has it

No client parses published submissions with it (they arrive as typed frames,
and the host's history pages carry the field, as the Edit/Delete test reads);
listing the field put the file over its line budget.

* fix(native-chat): retire a kept send's local copy instead of only hiding it

The outbox reconcile and the send disposition drop an entry whose submission
the host rejected as kept as a card, as they already do for a Stop's
withdrawal, so the copy never comes back as "Not sent / Retry" once the
submission falls out of the loaded page. The projection reads the reconciled
outbox, so its separate filter goes.

* test(native-chat): move the queued-message rig's scripted provider into its own fixture

The rig fixture grew past the 300-line limit once main's changes merged in.

* fix(native-chat): hide a kept send by its own record, not by its card still existing

The transcript hid a rejected send while a queued card held it under its id, so the card's Edit or
Delete brought back a "Not sent" row. It now reads the send's own keptAsQueuedMessageId, which the
host records with the rejection, and the live card list is no longer threaded to the transcript or
the delivery notices.

* refactor(native-chat): move a sent message's row writes into their own journal collaborator

The journal store went past its line limit once main's ledger receipt joined this branch's
transaction hook. The submission and dispatch-transition writes, and what commits in their
transaction, now live in JournalSubmissionWriter; the store's methods delegate to it unchanged.

* fix(native-chat): list a kept send's card id in the submission schema

The schema drops keys it does not list, so a reader that kept a parsed submission would lose
keptAsQueuedMessageId and source, both persisted with the row. The submission schema and the
failure fact it shares with item bodies move to their own modules, with room for both fields.

* test(native-chat): match the transcript and outbox hook signatures main and the swap changed

* test(native-chat): import the journal types once in the queue-delivery test

* fix(mobile): a resend the host kept as a card shows no error and returns no text

The host answers a resend of a message it kept as a card with that
message's rejected submission, marked keptAsQueuedMessageId. The phone read
it as any rejection: "Message not sent" and the text back in the composer,
while the card showed the same text. It now answers like a queued send, as
the desktop's send disposition does: the id is spent, no error, and the card
holds the text.

* test(native-chat): pin that quit's first step stops the queue's hand-off

Quit now stops delivery, the queue drain included, at its first step
(stopDelivery), before teardown drains recovery. The drain-step quit test
runs from that step as well as from the flush.

* test(native-chat): give cards their source and store unknown sources as another build would

#25078 made a card's source required, so the tests that insert a card pass the
person's. The hold's unknown-kind and unreadable-source cases now rewrite the
stored row the way a newer build would leave it, instead of casting a type.

* refactor(native-chat): stop delivery and the queue drain in one line at quit

Main's #25159 left the host at its line limit; quit's stop now disposes both in one
expression instead of a block.

* test(native-chat): hold the drain step without reading the call stack

Bun formats a method's stack frame without its class ("at step"), so the quit
test's caller check never matched, the step was never held, and both cases timed
out once CI ran Vitest on Bun (#25840). Only the drain step heals owed queue
bookkeeping, so the hold needs no caller check.

Subject: [PATCH 126/167] fix(native-chat): reasoning rows with a real
 open/finished state, and readable Claude thinking (#19221)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* fix(native-chat): render structured reasoning as collapsible messages

* fix(native-chat): align expanded reasoning with summary

* fix(native-chat): place reasoning chevron after summary

* De-emphasize reasoning headlines with observed timing labels

* Exclude later turn work from observed reasoning duration

* fix(native-chat): give reasoning rows a host-owned open/closed lifecycle

A reasoning row now says whether its block is still streaming (`state`)
and, when the host saw it end, when (`completedAt`). The row's own
start is its first-write time, so "Thought for N s" is measured on the
execution host instead of by whichever window happened to be watching.

Rows open with their first non-empty text and close on every path that
ends them: the block's final frame, a new message in the same stream,
every Claude turn end through one hook on the open turn, Codex
item/completed, turn and session settlement, active-item eviction, and
both host sweeps for a dead generation. Closing writes are lifecycle
writes so backpressure cannot leave a row open. Rows without the field
(older hosts, older journals) never read as live.

The reasoning row's headline reads the row's lifecycle and its own
turn's liveness: Thinking while open in a running turn, then Thought
for N s, Thought when no span was seen, Reasoning when the host kept no
lifecycle.

* feat(native-chat): ask Claude for readable thinking summaries

Under Orca's launch the Claude CLI streams thinking blocks with empty
text, so no reasoning row ever had anything to show. Pass only
`--thinking-display summarized`: it fills thinking blocks with the
API's summaries without turning thinking on, so a user who disabled
thinking keeps it off.

Orca runs the user's own binary, and a CLI older than the flag exits on
it before the session starts. The launch probes the binary it is about
to run, overlapping the rest of launch resolution, and passes the flag
only when that probe has already answered with 2.1.94 or newer. A slow
or failed probe never delays a launch and is never remembered; a
successful one is kept per binary until the binary changes.

* test(native-chat): type the superseding send in the reasoning lifecycle test

* fix(native-chat): stop reading an ended reasoning row as thinking

The spinner line infers "Thinking" from the newest root row being a
reasoning message. With summaries on, a closed reasoning row stays the
newest row while Claude streams a tool's input, so the line read
Thinking for the whole Write. A reasoning row now counts only while its
own state is running; a row from a host that keeps no state reads as
before.

* fix(native-chat): measure reasoning from the block's start, not its first text

A row opens with its first summary text, which trails the thinking
block's start by seconds, and the journal stamps a row with its queued
append time. So "Thought for N s" read 1 s for blocks that ran 4.65 s
and 12.95 s. The block registry now records the host time at each
block's content_block_start (else its first delta), and every write of
that block's row carries it as the row's observed time; the close keeps
the frame's own receipt time. Codex reasoning rows likewise carry their
item/started time.

* perf(native-chat): stop rewriting the reasoning row for every thinking token

Claude sends a thinking_tokens frame after every thinking delta. Every
frame the stream path did not consume forced the streamed text out
first, bypassing the checkpoint widening and the coalescing window, so
a single thinking block was rewritten and republished once per token:
212 full-row writes and 258 KB for one captured block. A frame that can
write no row (token tallies, stream deltas no registry carries, pings)
no longer forces that flush; every frame that can write still does.
The same block now takes 14 writes.

* fix(native-chat): time Codex reasoning by receipt and close evicted rows

Codex summary text lands 13-50 ms before item/completed, inside one
coalescing window, so a reasoning row's first write can be its
completion. Item boundaries are now stamped with their host receipt
time the way turn boundaries already were, so a retried or buffered
delivery keeps it, and the item translator falls back to the host
clock rather than Date.now(). The row carries its item/started time on
every first write, including the completion, so its span is
item/started to item/completed.

An evicted active item is now closed from the text streamed so far,
like both settle paths, and the eviction runs before the incoming item
is tracked: tracking first let the stream bound drop the evictee's text
before the eviction could close its row, stranding it running.

completedAt now has one meaning everywhere: the host time the message
was seen to end, or the end of the turn or stream that cut it off;
absent only when no end was seen live.

* refactor(native-chat): keep the Codex streaming body translation pure

The streaming translation preserves a reasoning body as-is again; the
stream writer, which is what knows the item has not completed, stamps
it running.

* test(native-chat): keep a re-collapsed reasoning row collapsed through a revision

* fix(native-chat): estimate a collapsed reasoning row as its trigger

A reasoning row renders collapsed, as one small button, but its height
was estimated from its full text: a 4,129-character summary reserved
about 950 px for a 24 px row, so long chats jumped as rows were
measured. It is now estimated at the trigger's height; opening the row
remeasures it.

* fix(native-chat): probe the CLI the launch will run, and learn from a refusal

The thinking-display gate probed `claude --version` with Orca's own cwd
and env, while the launch spawns with the workspace's cwd and the shell
env. Behind a version manager's shim those can pick different CLIs, so
the probe could approve a CLI the launch never ran, and an older CLI
exits on the unknown flag before the session starts. The probe also
only counted if it had already finished when resolution did, so a
first launch, or the first after a CLI update, usually went without
the flag.

The probe now runs with the launch's own resolved cwd and env, is keyed
by the binary and the workspace, and a launch waits up to 200 ms for it
(about 3x the probe's measured p95) before going without the flag. Only
answers are kept, so a slow or failed probe is asked again next launch.
A child that exits with commander's "unknown option '--thinking-display'"
marks that binary in that workspace so the next launch skips the flag;
that one start fails exactly as any CLI startup failure does today.

* test(native-chat): type the thinking-display probe mock with both of its parameters

* fix(native-chat): recheck the account switch after the probe, last as before

Moving the invocation ahead of the probe, the transcript check and the
permission mode put its account-switch recheck before those awaits, so a
switch that began during them launched unchecked. The invocation is the
last await again. The probe gets its own env from the same sources the
launch uses, the inherited env and the overlay with the CLI's runtime on
PATH, built by the same code, minus every credential: asking a CLI its
version needs none.

* fix(native-chat): wait up to 1.5 s for a cold probe, and remember every outcome

200 ms only covered a warm CLI; a cold disk, a node install or an
antivirus scan exceeds it, and that chat's child then ran its whole
life without summaries. A launch now waits up to 1.5 s, once per binary
per workspace, measured from when that binary's probe began, so a later
launch never waits again on a probe already past it. The probe gets its
own 10 s kill timeout, and every outcome, including no version printed,
a failure or a kill, is kept for the binary's life, so a probe that
hangs costs one launch rather than every one. A refusal seen while a
probe still runs wins over its late answer.

* fix(native-chat): leave Thinking to the activity line while reasoning runs

A reasoning row still being written drew a pulsing "Thinking…" header
right under the turn's activity line, which already says Thinking: two
live indicators for one fact. In a running turn an open reasoning row
now draws nothing and reserves no height; it appears when it closes, as
"Thought for N s". A row from a host that keeps no state, a closed row,
and a row left open by a turn that ended draw as before. The row's
Thinking headline is gone with its catalog key.

* fix(native-chat): end every unfinished Codex item through one rule

A reasoning completion with no text of its own left the row its stream
wrote running for good: the completion translated to nothing and the
item left the active set, so no settle could reach it. It now closes
from the text streamed so far.

Settlement, eviction and that completion now build an unfinished item's
row through one choice (the streamed text when there is any, else the
item as it started) and end it through one rule. An evicted file change
with streamed tool output no longer keeps that output as its patch; it
reads as interrupted, as a settled one does. A completion whose start
was never recorded claims no span, so it reads "Thought".

* fix(native-chat): catalogue Claude's stream keep-alive as benign

An uncatalogued `ping` stream frame classified as substantive, so the
fallback wrote a visible "claude · message:stream_event:ping" row, and
since such frames no longer force streamed text out first, a ping
inside a coalescing window landed above the open reasoning row. A ping
is now benign: it writes no row.

* fix(native-chat): bound finding the binary by the probe budget, and keep it LRU

Resolving the command's real path and its mtime was awaited before the
budgeted wait, so a slow filesystem could hold a launch indefinitely;
it now counts against the same budget, and running out caches nothing.
The cache is least recently used rather than first written, and holds
32 binary-and-workspace entries rather than 16.

* feat(mobile): collapse reasoning rows the way desktop does

With summaries on, every Claude turn now carries reasoning text, and the
phone drew all of it inline, dimmed, between the prompt and the answer.
Mobile now draws a reasoning row as desktop does: collapsed to "Thought
for N s", "Thought" or "Reasoning", its text mounted only once opened,
and nothing at all while the row is still being written in the live
turn or has no text. The headline and the visibility rule live in one
shared module both clients read, so they cannot drift.

* fix(native-chat): let a failed CLI probe heal instead of latching

A probe killed at its timeout, failing to spawn under a loaded boot, or
printing no version was cached as "no flag" for the binary's life, so
that workspace never got summaries again in that run. Only a version
(either side of the floor) or the CLI's own refusal is kept for good
now; a probe that gave no version is kept for 10 minutes, so a hung CLI
still costs one wait per stretch and a boot-time failure heals.

* docs(native-chat): say exactly what the version probe's env leaves out

* fix(native-chat): record a Codex item's start whatever its first frame carried

The start was recorded only for an item/started that wrote no row, so a
reasoning item that started with text lost it and its completion
claimed no span. Every tracked item/started now records its receipt
time, and the started write carries it too.

* fix(mobile): label the reasoning toggle and give it a full touch target

The toggle now tells a screen reader what it is, "Reasoning: Thought
for 3s", as desktop's prefix does, and reaches a 44 pt target. The
shared English copy stays private to the module that formats it.

* refactor(native-chat): build reasoning rows from one provider-neutral helper

Claude, Codex and the terminal sweeps each built the reasoning row body and
its running/ended stamp themselves. They now share journal-reasoning-row:
blank text journals no row, text is bounded the same way, and an end carries
completedAt only when the host saw it.

* refactor(codex): move the active journal item type into the contracts file

codex-unfinished-item-body imported the type from the settlement module,
which imports values from it.

* test(claude): read the launch PATH the way Windows spells it

* test(claude): compare the probe's PATH to the launch's without Orca's CLI dir

When the CLI's directory also holds node (Linux CI's /usr/local/bin), the
runtime pairing puts that directory first, ahead of the Orca CLI directory the
launch adds, so the launch PATH no longer ends with the probe's. Both still
resolve the same claude and shims. The test now checks that exactly, for a CLI
with and without a sibling node.

* feat(native-chat): lead the reasoning row with a brain glyph in the tool-row column

* fix(native-chat): route the reasoning glyph through the shared icon names, keep its chevron findable, and match it on mobile

* fix(mobile): keep the long-press actions sheet on reasoning rows for Android

* fix(native-chat): forward every exit argument through the thinking-display connection wrapper

* refactor(codex): keep the receipt-timed notification methods with the event they stamp

* feat(native-chat): read an open reasoning block through the one live "Thinking" line

While the agent's open reasoning block has text, the turn's live activity line is its
disclosure: collapsed by default, expandable to the live text (capped and scrollable), and
the block's row draws nothing meanwhile. When the block ends, its row appears in place,
open if the reader opened it live, because the line and the row read one disclosure key.
Which block the line discloses is derived from the line's own render condition, so a row
is never hidden while nothing on screen shows it; any other open block (a subagent's, or
one a prompt pushed off the line) draws as "Reasoning". Desktop and mobile alike; no host
or wire change.

* fix(native-chat): a slot kept for its turn bar or diff rollup no longer draws its message

The transcript row drew the message of every message slot, while the slot builder pushes a slot
for a row it declined to draw whenever that row also carries its turn's bar or diff rollup. So the
open reasoning block the live line discloses still drew as a "Reasoning" row when it was a
provider-opened turn's first row or the last row of a turn that changed files, and one click
opened both. The builder's decision now travels on the slot (`drawsMessage`) and the row draws
only the bar and rollup when it is false; the row-level `folded` guard it made redundant is gone.

* refactor(native-chat): draw the live line from one shared value, with one live region

Desktop and mobile now render the live activity line from one pure function,
`nativeChatLiveLine`: whether it draws, what it says, and the open reasoning block it
discloses with the text it has so far. The open block's row is hidden from that same value,
so desktop no longer restates the line's render condition beside it, and the lines no longer
re-derive the text.

The line keeps one element, and so one live region, through every state; only its trigger
and body come and go, so a screen reader hears "Thinking" and the label after it. On mobile
the live text gets the finished row's Android long press (copy or select through the message
actions sheet), the line's touch target is the row's 44 pt, and its label and body sit in
the finished row's column so nothing moves when the row takes over.

* fix(mobile): keep the live text's actions sheet on the block it was opened for

On Android the sheet opened by a long press on the live reasoning was a flag gated on a live
block: it vanished when the block ended, mid Select text, and the stale flag reopened it
unprompted on the next block. The sheet now holds the message it was opened for.

* test(native-chat): the reasoning body owns its tone, live and once landed

Rendered QA on a pre-merge build showed the live line's open reasoning in full foreground and the
landed row's in muted text, so it dimmed as the block landed: the body set no colour of its own and
inherited one from wherever it was mounted. Since the main merge (017ad743fa5) the body carries the
chat's faint tone itself; this pins that, and that the line and the row draw the same body.

Subject: [PATCH 127/167] fix(tabs): stop tab and close tooltips firing while
 grazing the strip (#25808)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* fix(tabs): delay tab and close tooltips past grazing

Tab title and close-icon tooltips fired near-instantly while dragging
across the strip: Radix's provider-wide skipDelayDuration reopens the
next tooltip with no delay for 300ms after any tooltip closes.

Scope a nested TooltipProvider to the tab strip with a 700ms delay and
skipDelayDuration=0, so each tab tooltip waits the full delay.

* fix(tabs): drop close-button tooltip and lengthen tab tooltip delay

Remove the hover tooltip from the tab close button entirely (aria-label
keeps the accessible name), and raise the tab-title tooltip delay from
700ms to 1500ms so grazing or scrolling the strip no longer pops a label.
Add an interaction test proving the delay is enforced and Radix's
skip-delay is disabled.

* fix(tabs): delay the agent-state glyph tooltip to match the strip

The tab's leading agent-state dot renders its own feature tooltip with a
hardcoded 200ms delay, so tabs with a live agent state (working/done/
needs-attention) popped almost instantly while plain tabs waited the full
strip delay — the 'every other tab' inconsistency. Thread an optional
delay through StateIndicatorTooltip/AgentStateDot and pass the tab-strip
1500ms from TerminalTabLeadingIcon; other surfaces keep 200ms.

* fix(tabs): remove the agent-state glyph tooltip on tabs

Hovering a tab's status glyph (spinner/check/question) popped its own
tooltip after 200ms, so tabs with a live agent state popped while plain
tabs stayed quiet. Remove that tooltip entirely via title={null}; the
glyph stays self-describing with its aria-label, and the tab title keeps
its tooltip. Reverts the now-unused delay plumbing.

* reduce the time down from 1500 ms to 500 ms

* fix(tabs): restore the close-tab shortcut hint with a slower delay

Close buttons share one TabCloseTooltip that waits 1s, longer than the 500ms tab-title tooltip. Also merges the tooltip provider tests.

Subject: [PATCH 128/167] fix(jira): tolerate malformed nested Jira status
 fields (#25656)

* fix(jira): reject malformed nested status data

* fix(jira): tolerate malformed status fields

* fix(jira): tie status parsing to the shared types

Allowed auth types and credential protections are coverage records over
JiraAuthType and SecretAtRestProtection, and the parsed status must list
every JiraConnectionStatus key, so a union or field change in the shared
types fails tsc instead of being silently dropped by this parser. Adds a
populated multi-site round-trip fixture and keeps connected statuses with
a malformed viewer or sites value connected.

* fix(jira): require every site and viewer field in status parsing

Site and viewer parsing now lists every JiraSite and JiraViewer key, like the top-level status, so a new optional field fails tsc instead of being dropped.

Subject: [PATCH 129/167] fix(native-chat): a long reply keeps its Working bar
 and Stop after a reload, from the host's turn (#25751)

* fix(native-chat): the chat reads whether a turn runs from the host, not the loaded history page

* fix(native-chat): the Working bar, card cancel and phone Stop follow the host's turn when its rows are not loaded

* fix(native-chat): keep the phone's Stop as it was, naming the host's running turn

Drops the conversation-wide phone Stop: the phone shows Stop only once a turn
is running, so a Stop naming no turn could not be reached and only changed the
ordinary Stop's request. Stop and card cancel still name the turn the host says
is running.

* fix(native-chat): the host's turn answer never outlives its host, and a half-loaded turn shows no edit totals

- A batch carrying rows restates the host's newest turn record, so one without
  it (an older host after a downgrade) drops back to the loaded rows instead of
  holding the last answer; the event coalescer merges by the same rule.
- A turn whose record is above the loaded rows is grouped only while it runs,
  and its loaded tail gets no "N changed files" total, which would undercount.
- "Thinking" reads the host's running turn too, so it shows when the turn's
  record is not loaded.
- The wire doc for observedAt says what the journal stores: creation time.

* refactor(native-chat): totals per turn come from their own hook, keeping the transcript list under its line limit

Also drops the chat zoom prop main removed from the unloaded live turn test.

Subject: [PATCH 130/167] fix(native-chat): a prompt card owns the chat input
 until its answer lands (terminal-backed chat, desktop and phone) (#25761)

* fix(native-chat): an answerable prompt card owns the chat input until its answer lands

* fix(mobile): a terminal chat's composer waits while its prompt card is up

* test(native-chat): type the prompt card fixtures without casts

* fix(native-chat): scope replies to acknowledged prompt occurrences

* fix(native-chat): preserve answer ordering and verified delivery

* test(native-chat): keep mock RPC client inside test boundary

* test(native-chat): place mock fixtures in the test-only scope

* Keep runtime comments within the module size limit

* test: preserve prompt delivery coverage in desktop CI

* Treat an older host's accepted write as delivered

A newer desktop or phone talking to a host that predates the write
settlement field read every accepted reply as "unconfirmed". Prompt cards
never dismissed, the phone showed "Response unconfirmed" on every tap and
ordinary chat messages were held as "Delivery unconfirmed".

The reader now uses writeSettlement when present and otherwise keeps the
host's whole-write accepted/refused verdict, exactly as before this branch.
Only prompt answers ask for provider settlement; ordinary callers
(follow-up delivery, paste drafts, option commands, composer sends) are
back on the original contract, so the legacy-handoff error class, its
flag, the sequence-only send helper and the mobile handoff hook are gone.

* Keep terminal-pane Escape on the plain accepted write

Every pane's Escape/Ctrl+C goes through pty:writeAccepted. This branch had
switched that IPC to wait for provider settlement, which dropped the
"remount this pane" signal for a daemon session awaiting recovery and could
stall later keystrokes behind a slow daemon acknowledgment.

pty:writeAccepted is back to its original local-only, synchronous write.
Prompt answers opt into settlement with requireWriteSettlement on the same
channel, and a settled refusal while the daemon recovers now sends the same
remount signal. Ordinary verified sends regain their original fallback write.

* Report a partly accepted local paste as unconfirmed

A settled local write split into chunks returned plain false when a later
chunk was refused after earlier ones were accepted. Callers read false as
"nothing was written", so chat showed "Message not sent" with a prefix
already in the agent's input. It now reports the write as unconfirmed,
the same verdict the paired host gives for a partial write.

* Hide the chat composer under a prompt card instead of unmounting it

When an approval or question card took the input region, the composer
unmounted. A message still waiting for its Enter was cancelled and its
bubble deleted after the draft had already been cleared, so the message
vanished without a notice; composer history was also wiped each time.

The composer now stays mounted but hidden while a card owns input, so its
state survives. A send that has not submitted yet is still stopped (its
Enter would answer the card), but its bubble stays with "Message not sent"
so the text is not lost. The composer ref is detached while hidden, so
root typing, paste and reveal focus never reach it.

* Keep an answered prompt hidden after the chat view remounts

The "answered" dismissal lived in component state. Toggling chat to
terminal and back, a PTY reconnect, or leaving the phone session and coming
back while the approved tool was still running brought the answered
approval back, and it then took over the input again.

Desktop now keeps the answered occurrence per pane outside the view;
phone keeps it per chat tab outside the controller. Both still retire it
when the pane observes the prompt clear or change, desktop also when the
tab retires, and both maps are size-bounded.

* Update the prompt-reply reliability gate for the review fixes

Older hosts' accepted answers now dismiss like acknowledged ones, the
composer stays mounted under a card, and answered prompts survive a view
remount. The gate's invariant, oracle, assertion list, new test files and
the two latest evidence runs now describe that contract.

* Let users hide a prompt card, keep Escape from denying, and gate only Send on the phone

The chat input could stay locked behind a card the host never closes (for
example after a Deny typed in the terminal), and Escape on a focused
approval card denied the tool even when the user meant to close a picker.

- A Hide control (chevron) on terminal approval and question cards, desktop
  and phone, hides that prompt occurrence and gives the input back. It writes
  nothing to the agent and uses the same per-occurrence dismissal as an
  acknowledged answer, so a new occurrence shows the card again.
- On desktop, Escape on a card now does the same Hide instead of Deny, and a
  card that appears while the user is typing no longer takes focus.
- On the phone, a card blocks only Send: typing, dictation and image attach
  keep working on the draft. The placeholder is back to the normal one.

* Fix two comments that still called older-host replies unconfirmed

Since an older host's accepted write now counts as delivered, the
requireWriteSettlement comment and the reliability gate's oracle said the
opposite of the code. Both now describe the current rule.

* Collapse prompt cards to a strip instead of hiding them, and close the round-2 gaps

Hide removed a card completely, so nothing on screen said a prompt was still
waiting, and several edges let the chat type into a live prompt.

- Collapse (the header chevron, or Escape on desktop) folds the card to a
  one-line strip above the composer; the strip's chevron expands it back.
  Collapsing writes nothing, frees the composer, and is disabled while an
  answer is still being written. Each pane or tab keeps the occurrence as
  answered or collapsed, so a remount restores the same view.
- Questions now carry the host wait's start like approvals, so an identical
  question in a new wait shows again (desktop and phone). A transcript-only
  prompt, which has no wait start, is dropped when the view stops observing
  it, and a transcript still loading no longer clears a dismissal.
- Desktop: while a card owns the input, the hidden composer cannot send or
  interrupt even if it still has keyboard focus, and the card takes focus in
  the same commit. A send the card retires no longer types Ctrl+U under it.
- Phone: an Ask hides the heuristic card read from the same waiting status,
  and the dismissal store is scoped by host, worktree and tab.

* Keep a collapsed card's partial answer, and scope its focus to its own pane

Collapsing a question card unmounted it, so expanding it again lost the
chosen step, selections and typed "Other" text; Escape typed in that text
field collapsed the card. A card arriving while the user typed in another
surface (sidebar, notes, a browser URL bar) also took the keyboard.

- The collapsed card now stays mounted but hidden (and inert on desktop)
  under its strip, on desktop and phone, so a partial answer survives
  collapse and expand. Escape inside the card's text field no longer
  collapses it. The question card shows the same focus ring as the approval
  card.
- A card takes focus only from inside its own pane (its hidden composer) or
  from the page body, never from a text field elsewhere.
- Desktop and phone share one dismissal store in src/shared, bounded by the
  existing scope-cache helper, which moves to src/shared with it.
- The card send imports the verified helper from its own module, and the
  phone files are split so each name matches its contents (header action,
  strip, lane selector).

* Return focus to the composer after a prompt card collapses

Since a collapsed card stays mounted, Escape or the chevron left keyboard
focus inside the now hidden, inert card. The composer's reveal-focus took
that as focus already in the pane and stood down, then the browser dropped
focus to the page body, so typed keys went nowhere.

Reveal-focus now treats focus inside a hidden or inert subtree as not in the
pane and focuses the composer. On the phone, collapsing a card also
dismisses the keyboard so a hidden reply field does not keep it.

* Keep the question card's collapse chevron beside its Cancel button

The question card header spread its three items with justify-between, which
put the new chevron in the middle of the header. The title now takes the
free space, as in the approval card, so the chevron sits next to Cancel at
the right edge.

* Run the prompt tests on the merged main

Main now runs Vitest under Bun, which resolves a long data: URL import as a
package name, so the SSH delivery test loads its bundled mobile module from a
temp file instead. The phone prompt harnesses mock the live line that main's
view now renders, and add Platform, which main's text-selection helper reads,
the same way main's own view tests do.

Subject: [PATCH 131/167] fix(runtime): build the host terminal model when a
 phone opens an idle terminal (#25780)

* fix(runtime): hydrate the host model on a phone subscribe to an idle PTY

After a relaunch the reattach leaves the host model empty and an idle TUI
never paints the byte that hydrates it. A phone subscribing then got the
hidden desktop pane's screen at desktop size, missed its viewport on every
resubscribe, and gave up with "Couldn't fit the terminal to this screen".

The subscribe now runs the existing renderer hydrate after the phone fit,
so the pane's screen is reflowed onto the PTY grid, and serves the phone
from that model instead of adopting the pane's desktop-sized screen.

Claude-Session: lane-host-hydrate

* test(e2e): phone subscribe to an idle relaunched terminal fits the phone

Relaunches the app over a live daemon PTY running an idle program, hides
its pane behind another tab, and subscribes as a mobile client at 47x40.
Before the host-side hydrate the first snapshot came back at the hidden
pane's size (135x60 here).

Claude-Session: lane-host-hydrate

* fix(runtime): join a renderer seed the resize repaint already started

A TUI answering the phone fit's SIGWINCH can deliver a byte before the
subscribe reaches its hydrate. That byte runs the same renderer seed, so
the subscribe saw "already hydrating", fell back to adopting the pane's
desktop-sized screen and seeded the model at desktop size again. Keep the
model's renderer seed beside it so the subscribe joins that result.

Claude-Session: lane-host-hydrate

* fix(runtime): join the resize repaint's seed without per-PTY seed state

Replaces the rendererSeedsByPtyId map with a check over existing state. If
an on-data seed was already considered before the subscribe's hydrate, the
subscribe awaits the model's write chain and reads the outcome from the
hydration state, the installed model and the provider-preferred flag.

Claude-Session: lane-host-hydrate

* fix(runtime): serve on-demand tab mounts to the phone from the PTY-grid model

A phone opening a tab not mounted since relaunch makes the desktop mount
it. The freshly mounted pane is hidden, so it answers at desktop size, and
both the mount-wait snapshot and the late renderer-mount-ready recovery
published that raw screen and seeded the model at that size.

The recovery seed now reflows the model onto the PTY grid, and both sites
publish the model's snapshot through one shared step, so the phone is only
served from the host model. A late recovery whose model moved past the
renderer high-water while it was rebuilt is still withheld.

Claude-Session: lane-host-hydrate

* fix(runtime): seed the model when a buffer read falls back to the pane

With no host model, a terminal buffer read answered with the desktop
pane's screen at the pane's size. The phone's resize restream and
pending-output recovery read through it, so a hidden pane could still
hand the phone a desktop-sized screen.

The fallback now seeds the model from that screen onto the PTY grid and
answers from the model, unless output landed during the read. The
desktop's own hidden-output recovery keeps the raw renderer fallback.

Claude-Session: lane-host-hydrate

* revert: drop the race join, on-demand mount and buffer-fallback rounds

Reverts 09f37efd0df, 5782bb58883, 67701cf87df and 944b57b8d85. The resize
repaint race and the on-demand tab mount are unreachable in production
(the PTY resize is fire-and-forget, and a tab mounted after the phone fit
replays the phone-grid daemon snapshot), and the buffer fallback only
reaches the phone with no model, which the subscribe hydrate now seeds.

Claude-Session: lane-host-hydrate

* fix(runtime): land the recovery seed on the PTY grid

A renderer recovery seed built the host model at the pane's size, which a
hidden desktop pane keeps after a phone fit resized the PTY. Reflow the
seeded model onto the PTY grid before replaying trailing output, and call
maybeHydrateHeadlessFromRenderer directly from the subscribe instead of
through a wrapper.

* test(e2e): retry terminal.list while the new tab's PTY binds

Subject: [PATCH 132/167] fix(codex): approve Orca's hook in managed Codex
 homes with Codex's own hash (#25742)

* feat(codex): ask Codex for its hash of Orca's hook in a throwaway home, cross-checked by position and path

* feat(codex): cache Codex's hook hashes per binary and version, asked one at a time and only by the app

* feat(codex): write a hook approval before its entry, and take back only its own on failure

* feat(codex): approve Orca's hook in managed Codex homes with Codex's own hash, written first

Managed homes (the shared mirror and per-account homes) no longer run a
background approval session. Status reads the home's files against Codex's
answer, and turning hooks off recognizes every saved version's hashes.

* feat(codex): managed homes approve Orca's hook with Codex's hash; drop their background approval

The previous commit carried only the managed resume's wait; this one holds
the managed install it relies on. Managed homes (the shared mirror and
per-account homes) write Codex's hash before the entry, fall back to their
own approvals when the answer is late, and strip Orca's entry only when
Codex itself answered with nothing to approve. Status reads the home's files
against Codex's answer, and turning hooks off recognizes every saved
version's hashes.

* feat(codex): only an Orca-launched Codex waits up to 3 s for the hook hash; warm it after PATH hydration

* feat(cli): name the file each agent hook status reports on

* test(codex): real-Codex contract for the derived hook hash in managed homes, on both pins and latest

* test(codex): type the hook-hash test fixtures and drop a duplicate import

* fix(codex): give a Codex launch its own install run instead of joining a plain terminal's

* test(codex): a user hook's approval stays put in an event Codex does not list

* test(codex): cover late answers, first-install mirroring, stale approvals and opt-out re-asking

* test(codex): a long managed home gets the daemon guard on its first install

* fix(codex): until Codex answers, approve a managed home's hook with Orca's own hash, as main did

A late, temporary or missing answer with no earlier approval in the home now
writes main's self-computed approval instead of leaving the hook out. Codex's
answer replaces it at the next install, a definitive answer (no hooks/list,
a refused cross-check, 0.128) never uses it, and status says the approval
is Orca's until Codex confirms it.

* test(codex): status flags an unapproved entry while Codex has not answered

* fix(codex): managed stopgap fills each missing event

Until Codex answers, a managed home kept only the events it had already
approved and dropped Orca's entry from the rest. Each event now keeps the
home's approval, else gets Orca's own hash, as main wrote every event. One
reader of the approval at Orca's entry serves the stopgap and status.

* refactor(codex): one Codex answer type, one in-process answer map, a disk-only memo

- One answer type with a kind (hashes, refused, pending) replaces two types
  and the three-field decoding at each caller.
- The lookup keeps one in-process answer per binary path, replacing the
  process memo, the global latest answer and the transient-failure map;
  status now reads the answer for the codex on PATH, not the last one asked.
- The memo file keeps Codex's refusals per version, like its hashes.
- Derivation takes the version it is given; one 30 s version-probe timeout.
- The launch wait reuses withTimeout, and launch prep passes launchesCodex
  down instead of a wait in milliseconds.
- Turning hooks off no longer forgets Codex's answer.
- Tests mock the derivation instead of a test-only resolver in production.

* chore(codex): list the approval reader for the CLI build; fold two identical scope checks

* fix(codex): count an approval at Orca's key only when it holds a hash Orca's entry may carry

* refactor(codex): one append for hook trust tables

* refactor(codex): the lookup keeps no entry for a missing Codex, and status checks the binary's fingerprint

Also names the lookup functions for the answer they return.

* refactor(codex): one stopgap reader for the managed home; the refused branch reads its own status

* refactor(codex): drop defaults and exports only tests relied on

* fix(codex): a failed ask of Codex stays pending instead of refusing its version

* chore(ci): run the real-Codex contract when the approval reader changes

* fix(codex): only a scratch home Codex loaded can refuse; the memo takes any hash and writes only on change

* fix(codex): hooks turned off during a launch's wait win, Off re-keys mirrored user approvals, and one rule says which hashes are Orca's

* fix(codex): an approval counts only under every key spelling Orca writes, as Codex on Windows reads only the backslash one

Subject: [PATCH 133/167] Fix Codex chat creation after its own model listing
 fails (#25754)

* fix(native-chat): keep Codex chat actions independent of catalog listing

* fix(native-chat): accept a Codex option pick before the model list arrives

- A live model, effort or Fast pick with no stored model list is kept as the
  next turn's intent instead of refused; Codex judges the model on turn/start
  and Fast without a known tier still sends Standard.
- Restoring saved Fast checks the saved model the turn will send, not the
  resumed thread's old model; the thread's effort is only reused for its own
  model.
- turn/start reads the exact Fast tier from the account's stored catalog at
  send time, so a tier any writer stored applies; the per-session copy is gone.
- Revert the delivery-loop extraction; that file matches main again.

* test(native-chat): pass the agent registry to the new acquisition attach tests

Merged main (#25159) requires agents on attach and an agent definition for catalog access; the PR's new acquisition attach tests and Fast-mode tests now pass them.

Subject: [PATCH 135/167] feat(floating-workspace): render the floating panel
 through the shared workspace surface (#22302)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* docs(floating-workspace): plan structured native chat in the floating panel

* feat(floating-workspace): resolve the floating workspace so a structured session can run there

* docs(floating-workspace): plan the unification onto the shared workspace surface

* chore(floating-workspace): keep the unification plan out of the branch

* test(floating-workspace): pin the structured route on capability, not workspace kind

The host half removed the 'floating-workspace' blocker; this pin still asserted it and went red
on the merge. Floating now routes like any workspace, so with capabilities un-negotiated the
resolver answers 'runtime-capability-unknown'.

* feat(floating-workspace): resolve the floating workspace's renderer row without a worktree record

The renderer had no Worktree row for the floating id: markdown creation, tab-bar path entry,
native-chat file links, attachments and model discovery all resolve a workspace through
getKnownWorktreeById and silently fail for it. The host already answers with a synthetic row
minted from the resolved floating directory; this gives the renderer the same single seam.

- The repo slice stores the host-resolved floating directory (floatingWorkspacePath); the panel's
  existing cwd resolution now writes it there instead of panel-local state, so there is one copy.
- findKnownWorktreeById mints the shared floatingWorkspaceToWorktree row from that path, local
  host only, cached while the directory is unchanged — mirroring the folder-workspace branch it
  sits beside.
- No consumer changes needed: every row-dependent path already goes through this resolver.

* feat(tabs): scope editor and browser activation to the owning workspace

Shared editor/browser activation always wrote global selection (activeFileId,
activeBrowserTabId, activeTabType). The floating panel is an overlay above the active
workspace, and its active tab must never become global selection — the invariant
documented in agent-auto-ack-targets.ts. Group-scoped activation is a prerequisite for
rendering the floating workspace through the shared tab-group surface.

- setActiveFile and setActiveBrowserTab take an optional target workspace, mirroring
  setActiveTabType: global selection moves only when the target IS the globally active
  workspace; per-workspace state always updates. Omitted keeps legacy behavior.
- The shared tab-group activation/creation commands pass their workspace, which is a
  no-op for the main surface (hidden surfaces are inert, so commands only fire on the
  active workspace) and confines floating activation to floating state.
- Terminal setActiveTab was already owner-scoped; now pinned by test.

* refactor(tab-group): separate the workspace drag scope and group tree from main-window chrome

Preparation for hosting the floating workspace on the shared surface, whose shell owns its own
titlebar tab strip and cannot mount the main chrome:

- WorkspaceTabDragLayer: the one dnd-kit scope for a workspace's strips and tree, extracted from
  TabGroupSplitLayout as a render-prop layer so a host can put shell-owned chrome (a titlebar
  strip) inside the same drag scope as the tree.
- TabGroupSplitNodeTree: the chrome-free recursive group tree, with an explicit tabStrip
  composition point on TabGroupPanel ('attached' keeps today's per-group strip; 'external' hosts
  render no per-group strip at all — a hidden one would register duplicate drag sortables).
- WorkspacePaneOverlayLayers: the retained pane hosts extracted from WorktreeSplitSurface so any
  tree host mounts the same pane lifecycle stack.
- TerminalPaneOverlayLayer gains ownsNativeChatToggleShortcut, following the existing rule that
  only one live workspace registers the chord.

TabGroupSplitLayout and WorktreeSplitSurface recompose these parts; the main surface's DOM is
unchanged.

* feat(floating-workspace): decide the panel's emptiness and layout atomically

An empty floating workspace has no tab-group layout at all (the slice starts empty and
hydration skips tab-less workspaces), while the shared group tree requires one. This model
resolves the two together: the panel shows its empty state exactly until the first tab exists,
and mounts the tree only with a layout plus a live focused group (stored focus, else the group
with an active tab, else the first group — matching the shell chrome's focused-group policy).

* feat(floating-workspace): render the floating panel through the shared workspace surface

The panel previously projected exactly one tab group and hand-rendered its panes, so any tab
that left that group — 'Move Tab to Split' creates a second group — stayed alive in state but
vanished from the panel. The body now mounts the shared group tree and retained pane overlay
stack for the floating workspace id, so every group renders, splits work, and structured chat
finally has a floating surface.

- One drag scope: WorkspaceTabDragLayer wraps the titlebar strip AND the body tree, so exactly
  one DndContext owns floating tab drag; strip drops reorder, body-edge drops split. The
  floating-only FloatingWorkspaceTabDragContext is deleted.
- The titlebar keeps the panel's single TabBar, now fed by the shared per-group workspace model
  of the focused group (tabStrip='external' keeps per-group strips out of the shell), with
  workspace-scoped activation commands so global selection never moves.
- Panes render through WorkspacePaneOverlayLayers: terminals gate on the resolved cwd and a
  settled viewport exactly as before; browser guests ride the shared retention layer; agent
  session tabs appear in the strip and render through the structured overlay.
- The empty state renders exactly until the first resolvable tab exists (stale unified entries
  still show it), per the atomic layout/emptiness model.
- Deleted: the single-group projection, the hand-written pane maps, FloatingBrowserSlot, and
  the floating pane-handle registry.

Known behavior deltas, both narrowing floating onto main-workspace semantics: Cmd/Ctrl+W with
panel (not terminal) focus closes the active tab rather than one pane of a multi-pane tab, and
a pane-owned close of the last tab no longer arms the panel focus reclaim (strip and shortcut
closes still do).

* test: re-register moved pane-ownership sites with the extraction

The retained overlay stack moved into WorkspacePaneOverlayLayers and the floating chrome model
became a guest-paint consumer; the structured-pane layering pin and the browser-guest retention
census both name files, so they follow the seam.

* fix(floating-workspace): mount the shared group tree in a flex frame so panes own their height

The tree's nodes size themselves as flex items, and the floating shell mounted
them in a block container, so every group body — and every pane anchored to
one via anchor-size() — measured 0px tall. Wrap the tree and overlay layers in
the same 'absolute inset-0 flex' frame the worktree split surface uses, record
the host contract on the tree, pin the frame in the panel's element-tree test,
and add a real-renderer e2e spec that measures group-body and pane boxes for
the single-group and split layouts (jsdom computes no layout, which is how the
0px regression passed 50k tests).

* fix(runtime): import the floating worktree minting the structured create path calls

floatingWorkspaceToResolvedWorktree called floatingWorkspaceToWorktree without
importing it. The module is @ts-nocheck (mechanically split runtime), so tsc
never saw the missing import and it only failed at call time — the structured
createSupport probe for the floating workspace threw a ReferenceError. Add the
import and a test that runs the real method, which fails on the missing import
where the typechecker cannot.

* fix(browser-pane): resolve floating and folder workspace paths in notebook navigation

navigateBrowserPageToUrl looked the workspace up in allWorktrees(), which has
no row for folder or floating workspaces, so their notebook navigations ran
with an undefined workspace path. Use getKnownWorktreeById, the same resolver
every other consumer was moved to.

* fix(tabs): keep a workspace's tab selection out of the main window's global selection

* refactor(floating-workspace): launch and close panes like every other workspace

* refactor(tab-group): let the surface that mounts tab groups describe its own chrome

* refactor(floating-workspace): render the floating panel through the shared workspace surface

* fix(floating-workspace): resolve the floating directory once on the host, and keep the controls' inset

* test(floating-workspace): pin the unified floating panel against the shared surface

* fix(floating-workspace): read the floating directory's paths through the app environment

The runtime now resolves the floating directory itself, and the headless
runtime has no Electron app, so the Electron path lookup threw there.

* fix(floating-workspace): keep the main window's frame and shortcuts out of the floating panel

The shared layout drew the main window's 4px titlebar band and sidebar seam
inside the floating panel, and the chat-view toggle fired in every workspace
on screen, so one key press flipped the main window's tab and the panel's.

* fix(floating-workspace): close floating tabs without taking over the main window

An unsaved floating note's save prompt made the floating panel the main
window's active worktree, and never appeared on a fresh launch because the
workbench that owns the prompt was not mounted. The prompt now shows a
floating note in the panel, and the workbench mounts while the panel holds
tabs.

Every close path now reads the same captured emptied-workspace reaction, so a
floating pane closing itself, its shell exiting, a group close, and an unsaved
note close all keep the panel's keyboard ownership, as a tab close already did.

* test(tab-group): pin that a dirty editor close carries its emptied reaction

* refactor(tabs): one rule for when a selection moves the main window's selection

Opening a file kept a floating-only exception while every other writer checked
whether the tab's workspace is the active one. Every writer now asks the same
question, so opening a file in a background worktree no longer points the main
window's editor selection into that worktree.

* refactor(floating-workspace): drop what the shared surface left unused

The terminal pane's imperative close handle lost its last consumer when the
floating panel stopped keeping its own pane registry, and the floating and
folder workspaces built the same lineage-free resolved worktree twice.

* test(floating-workspace): type test fixtures without casts and drop the removed pane ref

* fix(floating-workspace): keep panel focus when a close lands after the panel emptied

Saving the last floating note closes it after an awaited write, so the panel
could render empty before the close armed its keyboard reclaim, leaving the
intent armed with nothing left to consume it. The panel now re-checks whenever
the intent arms as well as when its tab count changes.

A pinned tab's confirmation took focus before the close read panel ownership;
the dispatcher now captures it before any prompt.

* refactor(floating-workspace): finish what the shared surface left behind

- The floating panel no longer accepts AI vault session drops: a session
  cannot resume into it, and its window-level drop handler fired beside the
  main window's.
- The last global-selection writers that spelled the active-workspace check
  inline now use the shared rule.
- Remove the save-dialog hook and item counter the old floating body used, and
  correct comments that said the workbench only mounts once a workspace exists.

* fix(floating-workspace): keep a floating leaf detach from changing the main window's tab type

* fix(floating-workspace): give floating chats their workspace identity and directory

* fix(floating-workspace): read one visibility fact for chat attention and auto-ack

* docs(floating-workspace): correct comments the shared surface made stale

* fix(attention): one on-screen rule for every tab's unread marker, main window and floating panel

* fix(agent-session): pin the folder a session launched in; floating chats resume there or refuse

* fix(native-chat): resolve a floating chat's file links, images and skills in its pinned folder

* fix(agent-session): open a floating chat's terminal handoff in its pinned folder

* fix(agent-session): surface refusal text on chat open, require the launch-directory rule, and keep bookkeeping from gating a launch

* fix(floating-workspace): wait for a floating chat's pinned folder and read panel visibility from the store

* test(floating-workspace): assert the toggle event without a cast

* fix(native-chat): show why a chat could not be opened instead of dropping the host's refusal

* fix(floating-workspace): close chat tabs through shared commands

* fix(i18n): remove obsolete floating editor loading key

* fix(floating-workspace): preserve tab ownership on activation and browser close

* fix(floating-workspace): keep terminal activation and focus reclaim in sync

* fix(readme): point translations at tracked media

* fix(floating-workspace): retain split surface with an empty focused group

* docs(tabs): describe workspace-owned activation accurately

* fix(floating-workspace): finish the main merge and name the pin a launch directory

Port what the merge left on main's newer shapes:
- The floating chat's "folder is gone" refusal becomes a typed reason,
  launchFolderMissing, worded like every other start refusal (copy, desktop
  words, five translations). Older clients drop the unknown reason and show
  the code's generic words.
- The PR's launch-folder tests run on main's journal-database record store;
  the attach-level case is a row in the pre-spawn refusal table.
- Tests main added since the PR's base learn the PR's close-queue settling,
  workspace-scoped notebook lookup and tab-stamped chat host.
- Move the store's visible-tab-index reads into the tab table, so the record
  store stays under the line cap with the pin writer in it.
- Drop a duplicate Worktree import the merge left in a @ts-nocheck file.

Rename the persisted field, the status summary field and the renderer slice
from workspacePath to launchDirectory: it records the folder a session first
launched in, not its workspace's path, and it has not shipped yet.

* Fix floating chat visibility, closes, and directory pinning

* fix(i18n): drop the floating save dialog's strings with the dialog

The floating panel now closes through the shared unsaved-changes prompt, so
its own dialog's six strings had no caller and failed the runtime-catalog
check.

* fix(native-chat): pin floating founders and retain pinned editors

* test: align auto-ack fixtures with unified tab visibility

* test: give the forget-status attach fixture a location

Attach now reads params.location to decide whether a new record is a floating founder, so the partial fixture needs the location real attach params always carry.

* test: type the forget-status attach fixture instead of casting it

The cast tripped the changed-code type-assertion gate.

* fix(native-chat): read a floating chat's model defaults in the folder it was created in

The model picker read the floating setting's current folder, so a chat
pinned to another folder could show that folder's project default.

* test(cross-version): give the stub host the record store the catalog read now checks

* test(claude): give main's thinking-display launch stub the store shape the resolver takes

Subject: [PATCH 136/167] fix(native-chat): chat copy that promised a retry, an
 update, or a coming change (#25157)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* fix(native-chat): chat copy that promised a retry, an update, or a coming change

- Subagent and background-task rows Orca can no longer settle read "status
  unavailable" ("2 agents with status unavailable"), not "no recent update",
  which implied an update was still coming.
- /compact or /clear refused behind an unconfirmed earlier message says "Wait
  for the agent to finish, then try again." There is no Retry for that message.
- The skills menu in SSH chats says skills can't be listed there; a skill typed
  by name still goes to the agent.
- A write the host refuses because this agent or location can't run as a chat
  says "Orca can't run this agent in a chat here." plus what didn't happen.
- Spanish gains the chat notice, background-task and subagent rows it lacked.

* fix(native-chat): whole count sentences for background-task states, and translation fixes

- Background-task header counts use one translated sentence per state
  (stateWorkingCount ... stateIdleCount), so Spanish and French can agree
  the state with the count; English output is unchanged and pinned by a test.
- es: subagent failed/idle/stopped counts and the waiting/blocked reasons
  read correctly for any count.
- fr: "listées" agrees with the feminine "skills" in the SSH skills line.
- ja: subagent status-unavailable count uses the 件 counter.
- Correct the refusal-table comment: hostUnsupported is also returned and

* fix(native-chat): es/fr background-task counts agree with any task kind

* revert(native-chat): leave the /compact unconfirmed-message refusal to its own PR

Restores main's settleEarlierMessage copy in every locale and drops its comment.
The refusal's behaviour, not only its words, is being fixed separately.

* test(native-chat): expect this PR's Spanish blocked reason in the tool-run language test

Subject: [PATCH 137/167] test(mobile): split the turn-disclosure test under
 the 800-line test limit (#25933)

* test(mobile): split the turn-disclosure test under the 800-line test limit

* test(mobile): baseline the split-out journal cases, which carry the original file's existing type errors

* test(mobile): make the turn-disclosure tests typecheck (render a Result component, not a host string) and prune the baseline

Subject: [PATCH 138/167] Add chat contrast and "Match terminal interface"
 (#25659)

* Add chat contrast and terminal interface matching

* Fix matching chat palettes and contrast controls

* Verify rebased appearance settings and preserve slider focus

* Memoize chat appearance and narrow settings subscriptions

* Wrap native chat tool-run summaries in the terminal font

* Use the matched chat foreground for inherited controls

* fix(native-chat): bound collapsed tool summaries

* Restore code foreground token for matched chat themes

* Reset all chat appearance controls through serialized writer

* Make terminal matching control chat size and contrast

* Verify terminal match controls on Chat settings page

* Share native chat appearance store selection

* Align matched chat palette test with full-strength foreground

* Keep tool-run header marks on the summary's first line

A wrapped two-line summary centered the leading icon, failure count, check,
and chevron between its lines. The header now top-aligns its items and gives
each mark a one-line-tall slot, so marks sit on line 1 and line 2 wraps under
the text.

* Explain terminal-matched chat controls on hover

While Match terminal interface is on, Contrast, Text size and Code text size
are disabled. Hovering any of them now shows a tooltip saying the chat is
matching the terminal interface and how to change it. Disabled controls drop
hover events, so an enabled wrapper carries the tooltip; with matching off the
controls render exactly as before.

* Name the tool-run alignment test case by summary length

Subject: [PATCH 139/167] fix(native-chat): start Windows chats without reading
 process creation times (#25718)

* fix(native-chat): start Windows chats without reading process creation times

Native chat on Windows refused to start ("Orca can't run this agent in a chat
here") whenever the process-table addon could not report process creation
times. Chat never needed them; only the bookkeeping around stopping the agent
did.

Windows now follows the common pattern: Stop ends the agent's tree with
`taskkill /T /F` on the child Orca still holds, and reports the tree gone only
when taskkill exits 0. A saved pid is never signalled after a restart.

- Remove the Claude and Codex location gate and the Codex launch refusal.
- A start time that cannot be read is recorded as unknown instead of refusing
  the session; recovery already releases such an owner without signalling it.
- Delete Claude's Windows creation-time descendant snapshot and its verifier.
- Codex's Windows teardown reports the real taskkill outcome.
- The renderer no longer waits on the capability flag; the host keeps
  publishing it for older clients (temporary).

* fix(native-chat): treat a Windows Claude exit after stdin end as a proven close

On Windows an idle Claude leaves on its own once its stdin ends, so every Stop
and close read as unproven: live background work settled as unknown and the
trace logged a close that "did not finish cleanly". As with the Codex close,
that exit is now the close and Orca makes no claim about processes Claude
started; a forced close still rests on taskkill's own report.

Also drop the Settings clause about Windows needing process start times, and
fix comments and the tracked process-enumeration doc that still described the
removed start-time gate and descendant snapshot.

* fix(native-chat): renew a held child's lease without a PID probe

An owner recorded without a process start time could never renew: the renewer
re-proves every live owner by PID identity, and with no start time and no
spawn-token echo that probe is indeterminate. The lease's last renewal then
stayed at the spawn, so a turn cut by an Orca crash was dated to its own start,
and every tick logged a failed renewal and split the batch into one store
transaction per chat.

The runtime now renews a lease for a child it still holds at the record's
fence and whose exit it has not received, recorded as a `held-child` match.
Receipt of the exit ends that proof before the exit is settled, and a restart
holds no child, so a dead owner's lease still expires and restart adjudication
is unchanged. Records this runtime does not hold keep the PID probe.

Also correct the identity probe's comment about shipped addons and note that
recovery's stop ladder is POSIX-only.

* fix(native-chat): keep a failed Windows taskkill unproven across a retried close

A Windows close counts Claude leaving on its own after its stdin ends as the
close. That shortcut also caught a retried close whose first attempt forced a
taskkill that failed: once the root exited, the retry returned true and the
failure read as a proven close. The tree reaper now records whether a reap
ever reached the live root, here, on an earlier close or from a transport
failure, and the shortcut applies only when none did; otherwise taskkill's
verdict stands and no new taskkill runs against the exited root.

Pin the platform on the existing tests that assume the POSIX close, and say
what `exit-proven` means on Windows in the acquisition-failure docs.

* fix(native-chat): derive a held child's liveness from the adapter's own handle

Lease renewal trusted a held child until the host settled its exit, and the
host hears of an exit late: Claude runs its close ladder and a store write
first, unexpected exits wait on one delivery chain shared by every chat, and a
Claude close that cannot prove its tree publishes nothing at all. A dead root
could keep renewing through that window, so a crash in it dated the cut turn
late. Renewal now asks the adapter, which owns the process handle and sees the
exit first: a child is held only while it is on record at the lease's fence
and its adapter still runs that exact acquisition with no root exit seen. An
adapter that cannot answer falls back to the PID probe. The stored
exit-received mark is gone.

The held-child read is now required by the runtime state and the renewer, and
a host-level test drives renewal through the real host wiring.

Subject: [PATCH 140/167] feat(native-chat): a solid, fading Jump to latest
 (#25759)

"Jump to latest" was a faint, see-through pill that popped in and out. It is
now a solid button that fades in and out, can't be clicked or tabbed to while
hidden, and keeps focus in the composer when clicked.

Subject: [PATCH 141/167] fix: stop Claude and agent helper processes when Orca
 quits or crashes (STA-9254, 1 of 2) (#25715)

* fix(supervisor): add a one-shot lifetime that runs past stdin end, and relay a provider's last output

A one-shot CLI (claude -p, codex exec -) reads its request until stdin ends, so the
supervisor's session rule (stdin end means the owner is closing) would stop it about
1 s into its answer. The one-shot lifetime passes stdin end through and leaves only
the owner-death watch and explicit signals to stop it.

The supervisor also exited as soon as its provider did, dropping output still in the
pipes when the owner reads slowly. It now waits, bounded, for the provider's output
to be relayed before exiting.

* fix(text-generation): run agent one-shots under the provider supervisor on POSIX

The Claude model-list probe, model discovery for every agent, and commit message,
pull request and branch name generation all spawned the agent CLI as a plain child
of Orca. If Orca quit, crashed or was killed while one was running, nothing stopped
it, and a CLI that hung kept running after Orca was gone.

They now run under the provider supervisor that native chat already uses, in its
one-shot lifetime, so Orca's exit stops the agent's whole process group however
Orca exits. A timeout or cancel asks the supervisor to stop (SIGTERM) and only
tears the tree down once it has had its full stop time; killing the supervisor
first would orphan the agent's group. A missing binary now reaches Orca as the
supervisor's exit 127, which is mapped back to the existing not-found message.
Windows and WSL keep spawning the agent directly.

* fix(supervisor): carry the provider argv on the supervisor's argv, map every spawn error back, and share one stop ladder

- The supervisor read the provider's command and arguments from one base64 JSON env string.
  Linux caps a single env string at 128 KiB, so an argv prompt of about 90-120 KiB, which
  passes the 120 KiB per-argument guard, failed execve with E2BIG. The provider argv now
  follows the supervisor script's '--' as real arguments; the env keeps only small fields.
- A supervisor that cannot start its provider reports Node's spawn error line and exits 127.
  That line now becomes the same error a direct spawn emits, so ENOENT still reads as
  'not found on PATH' and EACCES or any other spawn error reads as 'failed to start'.
- stopSupervisedProvider is the one ask, wait and force ladder: it gives a supervisor its full
  stop time before forcing. Agent one-shots, the Codex app-server close and the Claude child
  exit proof now share it, with the same requests, bounds and forced steps as before.

* fix(supervisor): report every provider spawn failure on one marked stderr line

Node throws most spawn failures (ENOEXEC, ENOTDIR, ELOOP, EPERM, ...) instead of emitting
them, and the supervisor had no catch, so it died with exit 1 and a stack trace that the
user saw as the agent's failure. A thrown or emitted spawn failure now exits 127 with one
marked line carrying whether it was thrown, its code and its message. Orca reads only the
last stderr line, so a runtime warning printed earlier cannot hide it, and maps it to the
message a direct spawn gave: thrown is 'could not be started', ENOENT is 'not found on
PATH', and any other emitted error is 'failed to start'.

* fix(supervisor): keep the user's Node options away from the supervisor and hand them to the provider

The supervisor runs Electron in Node mode, which honours NODE_OPTIONS and
NODE_REPL_EXTERNAL_MODULE. A user value such as a --require of a missing file stopped
the supervisor from starting, breaking even native CLIs like Codex that never load it.
The launch now takes both out of the supervisor's environment, carries them in its spec,
and restores them for the provider only, so a Node-based CLI still gets them.

* fix(text-generation): file a forced agent one-shot teardown under its own breadcrumb site

The forced tree teardown recorded every self-initiated kill as the Codex app-server's, so
a forced commit-message or model-discovery stop read as a Codex teardown in crash
breadcrumbs. The teardown now takes the caller's site; source-control stops pass the
site their Windows tree kill already uses.

* test(text-generation): cover the supervised stop under timeout and output limit; name the direct-child suites

The commit-message suites that drive fake children spawn them directly, the unsupervised
shape Windows and WSL use, so they now say so. The supervised POSIX stop gets its own
compositions: a timed-out Codex generation settles at once but holds the Codex home until
its supervisor has stopped (faithful fake, fake timers), and an agent that floods past the
output limit is stopped through its real supervisor with no process left behind.

* test(text-generation): run the direct-child suites on the Windows path and cover supervised discovery

The commit-message suites that drive fake children mocked the supervisor away on POSIX, so
they asserted a direct root SIGKILL that production no longer takes there. They now pin the
platform to Windows (with an empty PATH, so host installs cannot answer a bare agent name)
and assert the Windows kill, taskkill included. The three tests that check the host's own
discovery spawn shape run on the host and read the agent argv past the supervisor's '--'.
Model discovery gets its supervised composition: a timed-out Codex discovery settles at once
but holds the Codex home until its supervisor has stopped.

* fix(supervisor): show a supervised spawn failure in native chat as the spawn error it was

Native chat's exit errors carry the provider's stderr tail into Details. Under the supervisor
a missing CLI left the supervisor's internal spawn-failure report there instead of Node's own
'spawn <cmd> ENOENT'. The report, its parser and a display formatter now live in one module;
the Codex app-server and Claude stream-json exit errors pass the tail through the formatter,
which turns a report back into the spawn error and leaves any other stderr unchanged.

* fix(supervisor): report a spawn that failed without a pid instead of crashing on its missing pipes

When the provider spawn fails outright (EMFILE, ENFILE), Node emits 'error' later and leaves
the child with no pid and no stdio. Piping stdin into the missing pipe threw first, so the
supervisor died with exit 1 and a stack trace and never wrote its spawn-failure report. The
pipes are now wired only for a provider that started.

* refactor(supervisor): share the stop of a supervised child process

Agent one-shots stop their supervisor with SIGTERM through the shared stop ladder, watching
the child's own exit. That adapter moves into one helper beside the ladder, so other
supervised children can use it with their own stop request instead of a copy. The caller's
breadcrumb site still reaches the forced teardown. Same request, wait and force as before.

* fix(supervisor): give a session provider its stdin end and grace when its owner dies

The owner-death watch went straight to the group SIGTERM and cancelled any stdin-end grace,
so when Orca quit or crashed a session provider such as the Codex app-server never saw the
EOF that lets it finish writing its state (auth.json, the state database). A session whose
owner is gone now closes as an owner's stdin end does: the provider's stdin is ended, it
gets the stdin-end grace, and only then the SIGTERM and SIGKILL ladder. A one-shot already
had its EOF at the end of its request, so its owner's death still stops it at once.

* fix(supervisor): kill the rest of the provider group once the provider exits on a stop

A requested stop waited out the whole SIGTERM grace for the provider's group even after the
provider itself had exited, so a SIGTERM-ignoring helper it left behind held every stop for
up to 3 s. Under a stop, the rest of the group is now SIGKILLed as soon as the provider has
exited, the same rule its own exit already follows.

* test(text-generation): cover a supervised Codex discovery past its output limit

Model discovery's supervised stop was covered only under timeout. A Codex discovery that
floods past the output limit now runs through a real supervisor: it settles with the
too-much-data error, its agent is stopped through the supervisor, and the next discovery on
the same Codex home starts only after that agent is gone. The direct-child suites' headers
now list exactly the supervised cases that are covered.

* fix(supervisor): close a provider whose owner is gone the way its owner closes it

Owner death gave every session provider the stdin-end grace, so after an Orca crash a
Claude session, whose close is a stdin end plus SIGTERM, could keep working on its turn
for a second with nobody watching. The spawn spec now names the provider's close request:
'stdin-end' (the Codex app-server drains and exits on EOF, then gets its grace) or
'stdin-end-and-sigterm' (Claude; the default). A gone owner gets that same request. One
constant per provider feeds both its spawn spec and its owner-side close, through one
requestProviderClose, so the two cannot drift. One-shots still stop at once.

* fix(supervisor): keep the SIGTERM grace for a session's group after its provider exits

Killing the rest of the group the moment the provider exited under a stop also reached
native chat's closes, so an MCP server, a tool's child or a dev server still in Claude's or
Codex's group was SIGKILLed mid-cleanup instead of getting the rest of the SIGTERM grace.
The early group kill now applies only to one-shots, where the saved wait was the point;
a session's stop is back to waiting out the grace for its group.

* test(claude): pin that Claude's spawn passes its close request explicitly

The spawn-spec assertion matched the default close request, so dropping Claude's explicit
request still passed. The test now checks that the spec is built with the exit-proof ladder's
own constant.

* refactor(codex): give the Codex app-server close request its own module

Other Codex app-server spawns will name the same close request as the connection does.
Holding it in its own small module lets them import it without the connection itself.

* build(cli): list the Codex close request and the provider supervisor in the CLI project

The command-line build runs the short-lived Codex app-server session, which will name the
same close request as the Codex connection. Listing the close request, the provider
supervisor it takes its type from, and the spawn-failure report the supervisor uses lets the
CLI project typecheck that import without pulling the connection in.

* test(text-generation): check the ENOEXEC start failure only where Node reports one

On Linux, glibc's execvp hands an executable that is not a program to /bin/sh, so both a
direct and a supervised spawn run it and it exits 127; only macOS throws ENOEXEC. The
not-a-program case now runs on macOS only; the path-through-a-file case (ENOTDIR) still

* test(native-chat): a Stop over a card sent now into the running turn keeps it paused

Red on main: Codex's turn end withdraws the steered hand-off and the queue
sends the card again as a new host turn, with no pause recorded.

* fix(native-chat): a Stop's queue pause holds a card whose hand-off is still unanswered

A card sent now into the running turn was still pending when Stop judged the
pause, so nothing was recorded; the interrupt then withdrew the hand-off, the
card went back to waiting unpaused, and the queue sent it again as a new turn.
The pause now counts a hand-off that may still return to waiting, judged with
the appended row applied, so a withdrawal lands under the pause and an
acceptance retires it in that same write. Codex and Claude both hit it.

* test(native-chat): the Claude re-send case fails on its diff, inside the test's budget

* test(native-chat): a pause held by an unanswered hand-off ends on every path that ends it

The provider's answer, the provider dying, the chat closing, a restart, a
withdrawal still owed at open, and a /clear (refused until the hand-off ends,
then carrying every waiting card paused 'cleared'); each ends with the queue
sending again.

* fix(native-chat): narrow the pause's settled hand-off, and assert the queued receipt's card

* refactor(native-chat): derive the queue's pause from Stop and Resume journal rows

Stop now appends one journal row where it takes effect, before the interrupt,
whatever the queue holds; Resume appends its own. The pause is a pure function
of the fold: the latest Stop with no later Resume and no later accepted turn a
person asked for. A /clear's carried cards name their source, which is the
replacement's 'cleared' pause. Host-origin turns never lift either.

One predicate decides which cards a pause holds; by default every waiting card
without a hold of its own, including one queued after the Stop. The drain's
consume re-judges it inside its own transaction.

The rows are tombstones of an id no item takes, carrying the mark: a released
host reads an unknown row kind as corruption and truncates the journal there.

Deletes the stored pause (recordPause, the retire hook on every appended row,
the settle-before-record step, mayReturnToWaiting and its row overlay) and the
tests that only proved it retires. The queued_message_pauses table stays in the
schema, unread and unwritten, for downgrade safety.

* fix(native-chat): a card queued after a Stop sends normally, never ahead of held ones

A Stop's pause now holds only the cards queued before its row, plus a steer it
withdrew, which returns to its own place. Each card records the journal
position it was queued at, and the one hold rule compares that with the Stop
row. A card queued after the Stop is a new instruction: it sends as usual, but
the drain still stops at the first held card, so it never overtakes them.
/clear's pause holds the cards it carried. Holding every card again is a
one-line switch in that rule.

* fix(native-chat): the queue's own send re-checks the no-overtake rule in its transaction

The drain's pick and its consume now read one function, nextSendableQueuedCard,
so a Stop row that lands between them holds a newer card behind an older held
one exactly as the pick would. Notes why Stop and Resume ride a tombstone row.

* fix(native-chat): stop creating the unused queue pause table

The queue's pause is derived from journal rows, so nothing reads or writes
queued_message_pauses. It was still created on every open "for downgrade
safety", but an older build creates it itself when it opens the database, so
the table only sat empty in every new database. The tests now pin that no
pause table exists.

* fix(native-chat): a Stop's pause never hides the restart pause

A Stop holds only the cards queued before it. The pause derivation still
returned the Stop alone whenever it was in force, so the restart pause was
never considered: a card queued after the Stop, written by a host process
that has since exited, sent by itself after Orca restarted, with no pause
header and no Resume. A /clear pause that held nothing could hide it the
same way.

Every pause in force is now derived. A card is held if any of them holds
it, and it names the first that does. The drain's pick, the consume
transaction's re-check and the published header all read that one rule;
the header names the pause holding the first card Resume would send.

* test(native-chat): pin the Stop's no-resend, lift and held-card rules

- The Claude and Codex Stop-withdraws-a-steer tests checked "not sent
  again" at one instant, before a queue ignoring the pause re-sends. They
  now wait for the stopped turn to end and re-check after a quiet window.
- The deleted-card test read a card queued after the Stop, which sends
  whether or not a person's turn lifts it; it now reads the Stop's pause
  before and after that turn.
- Unit cases pin that a Stop holds a card with no recorded position and one
  queued before a rewind.

* refactor(native-chat): a Stop writes one Stop event with its reason, turn and caller

The Stop row that paused the queue becomes the general Stop event
{ reason, turnId?, at, caller? }, whose reason is the host's existing stop
cause. It still rides a tombstone of a host-only id (a released host deletes
the journal from the first unknown row kind), and Resume keeps its own marker
on its own id. Only a person's Stop (reason user-stop) pauses the queue.

* test(native-chat): a rewind keeps a lifted /clear pause lifted and restates the same Stop event

* test(native-chat): pin that Stop and Resume rows never reach apps or count as history

* test(native-chat): only a person's Stop event pauses the queue

* test(native-chat): pin that a Stop's event precedes the interrupt and the at-start stop

Through the real host: the event names the turn and who asked and is in the
journal when the interrupt reaches the agent; at an agent still starting it is
there before the start is ended and holds a card queued before it; an idle Stop
writes one only when it withdrew a send; and the queue's claim re-judges a
pause that landed after its pick.

* test(native-chat): a card held at a starting agent is checked before the Stop's timing

Also says precisely what the claim's in-transaction pause check defends
against: the Stop and the drain share one serialized lane.

* test(native-chat): a released build keeps and folds a journal holding Stop events

Replays this build's rows from the released build's own journal database: every
row is kept, the history after the Stop still folds, and an older client is sent
only removed ids no item uses.

* style(native-chat): format the Stop event changes

* test(native-chat): type the released build's exports through one checked helper

* fix(native-chat): the Stop/Resume row guard narrows to those tombstones only

* test(native-chat): run the Stop-event downgrade test in CI, and cover a writable downgrade

The Stop-event downgrade test ran in no CI lane: unit shards exclude the
cross-version folder, and the cross-version lane runs a fixed file list that
did not name it. It is now on that list.

Its only case replayed the rows into a release's own fresh database, because
that release cannot open the current host database. A second case opens the
journal this build wrote with a main build that shares the database: it opens
writable, keeps every row, appends, and this build then reopens it with the
person's Stop still pausing the queue.

* fix(native-chat): a Stop that stops nothing new writes no Stop event

A Stop reaching a running agent wrote a Stop event on every press. Two
presses before the first interrupt landed wrote two events, so a card
queued between them counted as before the latest Stop and was held,
though a card queued after a Stop should send normally. A Stop naming a
turn that had already ended, as a phone sends late, also wrote an event
for a turn it never stopped.

It now writes one only when it withdrew a queued send, or stops something
no event records yet: not a turn the journal no longer runs, and not the
live turn a Stop still in force already names, unless a card was handed
over into it since, which this Stop's interrupt sends back and must hold.
The interrupt and the "already finished" note are unchanged. A Stop at a
starting agent still always writes.

* test(native-chat): pin that a later host, eviction or close Stop never lifts a person's Stop

* chore(native-chat): put each Stop-row doc on its own declaration, and say only user-stop is journaled

* fix(native-chat): any later Stop event ends a person's Stop pause

A person's Stop paused the queue until their next accepted turn or Resume,
and a later Stop of another reason (the host stopping the agent, an
eviction, a close) was ignored. Now the pause is the latest Stop event's:
a later Stop of any reason ends a person's pause, and only a person's Stop
pauses. The fold keeps the latest Stop event whatever its reason.

An eviction of a resting chat writes no Stop event (a Stop that stops
nothing writes nothing), so it cannot release held cards; a test pins that
no event means no lift.

* fix(native-chat): a second Stop press is a repeat even when the first came before the turn showed

A Stop pressed before the agent's turn shows in the journal (before
Claude's echo, or before Codex opens the turn) records no turn. A second
press once the turn showed compared that missing turn with the live one,
wrote a second Stop event, and held a card queued between the presses.

A repeat is now judged by what was sent since the Stop in force: with
nothing sent after it (a refused send aside), a Stop that named no turn,
or named the live one, is repeated and writes nothing. Anything sent since
and not refused, including a send whose fate is unknown, makes the new
press write, since its interrupt may send that card back to waiting.

Tests: the two-press case across the turn showing; a steer between the
presses settled unknown; and a Stop naming a turn that ended while the next
card is sent but shows no turn yet, which writes and holds that card. The
fold test that claimed an eviction path is renamed.

* fix(native-chat): the queue's pause ignores a Stop or Resume row holding a value no build writes

A Stop or Resume row's value is read from disk with no shape check, and
the pause fold stored whatever it found. A stored `stopEvent: null` would
then throw on every pause check for that chat: the queue's pick, its
send, and every queue update to clients. No build writes such a row, so
this is hardening.

The fold now reads a Stop only when it is an object with a string reason
and a finite time, and a Resume only when it is `true`. Anything else is
ignored: it pauses nothing and ends nothing. The row is still not treated
as malformed, which could cut the history short.

* fix(native-chat): a Stop still reads as yours after Orca restarts before the turn ends

Every stop that ends work now writes the Stop's event before it ends the child: a
person's close of the chat, an eviction (worktree teardown, orchestration stop, tab
cleanup) and the idle sweep's stop of a start that never landed. A stop that ends
nothing writes nothing, and quit writes none: its resume marker records why.

The turn-end write reads the latest Stop event where every turn row is built, so the
adapter's settle, the host's fallback and the relaunch's settle all agree: a turn a
person's Stop or close named, ending with no verdict of its own after that Stop, ends
as their cancellation. A relaunch's probe-bounded end is no earlier than a Stop that
found the turn running. When the provider refuses the interrupt and the turn runs on,
a refusal row answers the Stop, so a later crash still reads Failed; pressing Stop
again after a refusal is a new Stop.

* refactor(native-chat): a stop no longer carries its cause; the turn's end reads the Stop event

The cause of a stop was threaded in memory from each entry through the host's stop
step, the adapter router and each adapter's close onto the `ended` it settled with,
and Claude kept a per-turn copy of a Stop it sent. All of that is gone: adapters
settle a turn they cut as interrupted with no verdict, the host's fallback does the
same, and the one rule where a turn row is built (`turnEndAfterStop`) reads the
journal's latest Stop event to say whether it was a person's.

- `closeSession` / `disposeSession` take no cause; `ended` has no `stopCause`.
- Claude reads an error result after a person's Stop as their cancellation from the
  journal's Stop event (through the event sink), not from a per-turn slot, and a
  refused interrupt is the host's refusal row, not `withdrawTurnStop`.
- An owed wind-down keeps no cause: its retry's fallback reads the Stop event.
- The mutation context's Stop passes no cause: its step already wrote the event, and
  the delivery loop's child-end reason is read back from it.
- A Stop pressed before its turn showed applies to the turn that opens under it,
  unless a send a person made since was accepted.

* test(native-chat): a turn a later send opened is no Stop's that named no turn

* test(native-chat): the restart test's death proof carries its detail

* refactor(native-chat): a refused Stop leaves no record; a Stop only ever ends the turn it names

The stop-refused mark is gone: its tombstone kind, its fold, the clock-keyed match that tied it to
a Stop, and the exception that let a second press after a refusal write a new Stop. A Stop that
stops nothing writes nothing. A Codex refusal names a turn that is no longer its active one, and
the Stop names that turn, so the turn running instead never reads as the person's by its id alone.

* fix(native-chat): a Stop pressed before any turn showed stops only the turn opened next

A Stop that named no turn read as the person's cancellation for every later turn that opened
after it, until a send a person made was accepted. The queue's drain, orchestration mail and a
restart continuation send as the host, so a turn they opened long after, cut by a crash, read
"Interrupted" as if the person had stopped it. The Stop now applies only to the first turn
opened after it.

* fix(native-chat): an older Claude's error end after a Stop pressed before its echo reads Interrupted

Claude CLIs before 2.1.91 end an interrupted turn with an error result that names no reason. The
translator judged whether a person's Stop explained it by its own copy of the Stop rule, which
ignored a Stop that named no turn, so a Stop pressed before Claude echoed the send read "Failed".
The translator now writes such an end as interrupted with no verdict and no error row whenever a
person's Stop may name the turn, and the journal's one rule decides as it writes the end.

* fix(native-chat): a person's Stop and /clear each name why they end the agent

The host's mutation path ended the agent with one "recorded" ending for every caller, which read
back the reason of whatever Stop event the journal held last, however old. /clear writes no Stop
event, so its end took an unrelated earlier reason. Each caller now names its own: the chat's Stop
`user-stop`, whose event its own step wrote, and /clear `user-close`, the user replacing this chat.

* fix(native-chat): a host stop judges whether it ends work after the provider's rows land

A close, eviction or host stop decided whether it ended a running turn from the journal as it
stood, while the provider's own rows (the turn its echo opened) could still be in the session's
event sink. A close landing in that gap wrote no Stop event, so the turn it cut read as news. It
now reads after the sink drains, as a person's Stop does, through the same check; a drain that
fails or takes over a second reads working.

* fix(native-chat): a Claude Stop naming a turn that just ended still marks the follow-up it cuts

A phone names the turn it last saw. When that turn had ended and a follow-up was still unechoed,
Claude's Stop interrupted the follow-up and ended the child, but the Stop's event named the ended
turn, so the follow-up's turn the child's end cut read "Failed" under "Cancellation requested.".
A Stop that ends the provider's session ends whatever is in flight, so its event now names the
live turn or none, and a Stop that names none binds the turn opened next. Codex keeps naming only
the turn the Stop names.

The Claude Stop turn-end tests move to their own file, since the session-ending Stop suite is at
its line budget.

* fix(native-chat): the idle sweep reads working by the same rule as a stop's event

The sweep judged a chat resting while a send whose reply was lost was still unanswered, but the
stop's event writer counts that send as work. So the sweep evicted it and wrote an evict event,
which ends a person's Stop pause and let the cards behind it drain on their own. The sweep's owed
work now reads the main agent working the way every session list and the event writer do.

* test(native-chat): an aborted eviction's injected drain failure lands on the eviction's own drain

A host stop now drains the session's sink once to judge whether it ends work, so the tests that
fail the eviction's drain-published step skip that first drain.

* fix(native-chat): the idle sweep's rest writes no Stop event; it evicts a send that never echoes

The previous commit made the sweep count an unanswered send as owed work, which pins a chat whose
admitted send Codex never echoes forever, and the sweep exists to retire exactly that. That rule
returns. The sweep stops only an agent it judged resting, so its eviction now writes no Stop
event, whatever send it retires: a person's Stop pause holds through it.

* fix(native-chat): stopping a start that carries no send writes no Stop event

A host stop, eviction or close of a starting child wrote a Stop event whatever the start carried.
A start with a send already reads working, so the clause only mattered for a start with none,
which ends no turn and no send: its event only lifted a person's Stop pause and bumped the idle
clock, which is why the idle sweep had been changed to close the conversation in the same pass.
The clause goes and the sweep is #24072's again. The child's end still reads host-stop, as before.

* test(native-chat): a Stop's pause across a restart is tested with a restart that writes no event

The rig's restart closes the chat with an eviction, which now writes a Stop event when work runs
and so ends a person's Stop pause. "A Stop never hides a restart's pause" then passed with no Stop
pause left to hide anything. Those tests, and the pause-lift test whose dropped assertion returns,
restart as a process that dies with no close, which like a quit writes no Stop event, and assert
that both the Stop's and the restart's pauses are in force first.

* fix(native-chat): a host stop of a turn a person's Stop is still ending keeps that Stop's reason

An eviction or host stop that landed while a person's Stop or close was already ending the same
turn wrote a newer Stop event, and the turn's end reads only the latest, so the person's Stop of
that turn read as news. A host reason now writes nothing while a person's Stop still decides what
runs: the live turn it names or bound, or, with none, the turn a send opens next. The person's
own close still writes. The E2 tests now open and end the stopped send's own turn, as Codex does,
so the mail turn after it is not the turnless Stop's.

* fix(native-chat): an older Claude's error on a later turn keeps its error text after a Stop

The translator left an error result that names no reason to the journal's Stop rule whenever a
person's Stop named the turn or none, but the rule binds a Stop naming no turn only to the turn
opened next. So a real error on a later turn read "Failed" with its error text dropped. The
translator now asks the journal's rule itself (`personStopDecidesTurn`, the one core
`turnEndAfterStop` and a host stop's in-force check share), so the two cannot disagree.

* fix(native-chat): a Stop of a start that never landed binds no later turn, whatever sent it

A person's Stop pressed while the agent starts names no turn, and the send it stopped is
cancelled before it opens one. The Stop then bound the next turn anything opened (orchestration
mail, a restart continuation, the queue's drain, all of which send as the host), so a host
eviction of that turn wrote nothing and its crash or close read as the person's cancellation. A
Stop that named no turn now binds only a turn no send journaled after it opened: any send since,
of any origin and not refused, opens its own. The E2 test's mail send is accepted as Codex
accepts it, instead of opening the stopped send's own turn first.

* test(native-chat): a rewind's restated turnless Stop binds no turn opened after the rewind

A Codex rewind restates a person's Stop still in force after the turns it keeps, at a new
sequence, so by sequence alone it would bind the next turn opened after the rewind. A send
journaled after the restated row voids that binding (the previous commit), which this pins.

* fix(native-chat): a relaunch settles a person's stopped turn with no "stopped while in progress" row

After a restart, a turn a person's Stop ended reads "Interrupted after N" with the muted mark, but
the relaunch still added the error row saying the provider stopped mid-response, which a live Stop
never writes. The settle now skips that row when every turn it interrupts is the person's Stop's
by the journal's one rule; a crash nobody stopped keeps it.

* test(native-chat): the unexpected-exit settle's journal fake answers whether a person's Stop decides a turn

* fix(native-chat): a host stop whose sink drain fails reads the journal as it stands

A host stop drains the session's sink before judging whether it ends work, and a failed or slow
drain read as working. So an eviction of an agent at rest wrote a Stop event that ended nothing,
which lifts a person's Stop pause, and a close wrote a person's event naming no turn. The drain is
now best effort: the stop goes ahead either way and only its record is at stake, so a failed or
slow drain leaves the journal's read as it stands. A person's Stop keeps its own rule.

* fix(native-chat): a Stop that named no turn applies only to a turn a send it stopped opened

A person's Stop pressed before any turn showed names no turn. It bound the first turn opened
after it, then (5ead1f6bccd) any turn opened by no later send, so a turn the host started for
a card the Stop held, or for orchestration mail, read as the person's cancellation, and a host
eviction of it wrote no Stop event when its send had been abandoned by the close first.

The rule is now the concept itself: a Stop naming no turn applies to a turn opened by a send it
stopped, one already handed to the agent at the Stop's position. Nothing new is stored. The turn's
row names the send that opened it (Codex: the submission's key; Claude: the echo, which the journal
aliases to the submission), and a handed-over send's item sits at its handover, so the target set
is derived from the journal. A card the Stop held is handed over after it, so it is no target; a
Stop of a start whose send never opens a turn binds nothing; a rewind keeps no submissions, so a
restated Stop binds no turn opened after it. With no turn running, a host stop defers to the
person's Stop only while every unanswered send is one it stopped. Claude's translator, which asks
before its echo row lands, passes the send its echo acknowledged.

* fix(native-chat): a host stop whose sink drain runs long reads the agent working; a failed one reads the journal

A drain past its bound may still hold the turn's row, while the echo's acceptance has already
landed, so the journal as it stands read nothing running: a person's close of that turn wrote no
Stop event and the turn read as news. The two drain outcomes now differ: one that failed has
nothing more to deliver, so the journal's read holds (as before); one still running reads working.

* test(native-chat): a host stop with no turn running defers only while every unanswered send is the Stop's

The branch had no test. An eviction with only the stopped send unanswered writes nothing; one
with a send made after the Stop still unanswered writes its event.

* fix(native-chat): a slow sink drain reads working only while an accepted send's turn row is due

The previous commit read every drain past its bound as working, so a host eviction or stop of an
agent at rest during a sink backlog wrote a Stop event that ended nothing and lifted a person's
Stop pause. A slow drain now reads working only when the latest send the agent accepted has opened
no turn the journal holds, the race it was for; otherwise the journal's read holds.

* test(native-chat): the host-stop control keeps the stopped send unanswered beside the later one

With both unanswered, the host writes only because not every unanswered send is the Stop's; a rule
that deferred when any one was would pass the old control.

* fix(native-chat): a steer is no send owed a turn when a slow drain judges a host stop

A slow drain reads working when the latest accepted send has opened no turn yet. A Codex steer or
a Claude fold is accepted into the running turn and never opens one, so a chat at rest whose last
send was a steer still read working, and an eviction lifted a person's Stop pause. Sends delivered
into a running turn, whose item carries that turn's scope, are skipped.

* feat(native-chat): a chat reads Stopping from the person's Stop until the work it stopped ends

The host derives it on each journal publish from the Stop's event, the live turn and the Stop's
own answer, and publishes it as an optional field on the session status and the main agent's row.
Clients present it: the chat's tail line and Stop control, the sidebar row, worktree ps and the
phone's row. The chat and the phone also read their own Stop press until its request answers.

* test(native-chat): pin Stopping on the phone and across mixed versions

* test: give touched fake journals and mocks their SAFETY notes

* test(native-chat): a turn waiting on the person reads attention, never Stopping

* test(native-chat): the sidebar row follows Stopping when it is the only field that moved

* test(mobile): the phone reads Stopping from its own Stop until the request answers

* test(mobile): type the held Stop request instead of casting it

* chore: keep the base lockfile (a local pnpm run rewrote it)

* fix(native-chat): narrow the Stop note's optional failure; type the phone test's reply

* test(native-chat): type the Stop test envelope's fields narrowly

* fix(native-chat): a Stop the agent declined, or whose child end failed, says so while the turn runs on

A Stop naming the turn that still runs, refused by the agent, now writes the
Stop's refused fact instead of 'already finished'. A session-ending Stop whose
child end fails while the work runs on revises its note to unconfirmed.

* fix(native-chat): Stopping holds while any press of the Stop took

A repeat press refused after an earlier press took no longer clears Stopping.
Exit early when the Stop named a turn that is not the live one.

* fix(native-chat): keep Stop enabled while the host says Stopping

Only this client's own Stop request in flight disables Stop and Esc. A repeat
Stop is how a stop the provider took but never answered escalates.

* fix(sidebar): every agent row says Stopping in place of its tool line

The dashboard row, which the sidebar's non-compact mode also draws, read the
last tool line while a person's Stop ended the turn. It now shares the compact
row's rule.

* fix(mobile): the worktree list sees Stopping change on its own

A snapshot whose only change was the host dropping Stopping compared equal and
was thrown away, leaving the row on Stopping.

* refactor(native-chat): fold the status feed in src/shared for both clients

The snapshot merge and the contact-loss strip move out of the renderer feed so
the phone folds the same stream the same way.

* feat(mobile): let phones read the structured session status stream

agentSession.subscribeStatus joins the mobile allowlist. The agent-session
methods move to their own file, which the at-cap allowlist spreads in, and the
allowlist test reads the Set instead of parsing the source.

* feat(mobile): the phone chat reads Stopping from the host, like the desktop

One status stream per client, opened on a host that advertises the status feed;
a refusal to phones reads as no feed. The chat reads Stopping from the host or
its own press, and holds Stop only while its own request is in flight.

* test: give the new fakes checked types or a SAFETY reason

* revert(native-chat): drop the refused-named-turn rewrite of a Stop's note

Codex can send its refusal before the turn's end frames, so reading the turn as
still live after a flush races; the Codex Stop that ends nothing is handled by
ending the process instead. The base's 'already finished' note and its test
expectation return. The Claude wind-down failure revise stays.

* fix(mobile): release the status stream when the host ends it; refusals last one connection

The feed now drops the handle of a stream the host ended or refused, so the
logical client never replays it on a later session. A refusal to phones holds
for one connection, so a host updated while the phone stays paired is asked
again.

* perf(native-chat): read the live turn's opener from its record when deriving Stopping

After a Stop that named no turn, every later commit walked and copied the whole
journal to find the live turn's record. The derivation now reads that record
off the rendered snapshot's tail and decides with the same rule.

* refactor(mobile): move the method-unavailable check into transport

The status feed imported it from the Files tab's fallback. No behaviour change.

* test(native-chat): a send after a Stop reads Working before its turn opens

Pins the derivation's running-only read of the newest turn: the stopped turn,
already ended, must not keep the next send on Stopping.

* fix(sidebar): the compact row leads with Stopping so a narrow sidebar keeps it whole

At the default width the row read 'Codex Chat - Stoppin…': the model and time
keep their room and the line truncates from the end. Stopping now leads the line
the way monitoring already does, so the chat name is what gets cut. Also pins
that the turn bar keeps its running clock while the tail line says Stopping.

* test(native-chat): the retry of a close whose exit was unproven writes no second Stop event

The idle sweep finishes a stop left owed with that stop's own cause. It is the same stop, so its
event stands alone and the child's end keeps the cause, for a person's close and an eviction.

* fix(native-chat): read and write a Stop's answer by the turn its event records

Stop notes are now one row per turn, keyed by the turn the Stop's event
records. Performing a Stop and deriving Stopping share that key. A refused or
unconfirmed answer never overwrites one that took at the same key; only a
session-ending Stop's failed wind-down downgrades it, and that step now revises
the note the Stop actually wrote, carried on the wind-down. Stopping reads the
turn's note whenever it was first written, plus newer notes no other turn owns.
Test fixtures gain the host logger and the phone's quietRepeatedStop.

* refactor(native-chat): read a Stop's target once for its event and its note

The chat's Stop now reads what it is aimed at (the named turn and whether the
Stop ends the provider session) once, and both its event and its note's key
derive their turn from that one value through the same rule. Adds the host test
for a Stop naming an ended turn on a provider whose Stop ends the session.

* fix(native-chat): the host never steers a message into a turn a Stop is ending

A queued card's Send-now, or a send made while a person's Stop ends the turn,
went to the agent as a steer into that turn. The delivery loop now holds any
waiting message while the host's own Stopping reading holds, and sends it as
its own turn once the turn ends. The Stopping reader also stops at the Stop's
position and looks the turn's note up by key, instead of walking the whole
journal.

* feat(native-chat): while Stopping, the composer says a message runs after the stop

Desktop and phone: the composer placeholder reads "Queue a message to run
after the stop" while the chat reads Stopping, and a queued card's Steer (and
the desktop's steer shortcut) is held. New key translated in all 6 catalogs.

* refactor(native-chat): the chat pane's Stop controls live in their own module

The pane went over its line limit once merged with main. Its Stopping reading,
the press that holds Stop, and the steer and placeholder it hands the composer
move to native-chat-structured-stop-controls.ts.

* fix(native-chat): hold a send at its handover, reading the feed's own Stopping

The hold was checked when the delivery step started, but the handover runs in a
later step after waiting on the agent's start, so a Stop landing in between let
a new send steer into the stopping turn. The check now runs at the handover.
It reads the status feed's projection for the commit instead of rendering the
journal again, so holding a send adds no journal read of its own.

* refactor(native-chat): one display status decides Stopping on every surface

agentStopDisplayStatus combines whether the agent works, the host's flag and
this client's own press. The chat pane, sidebar and dashboard rows, and the
phone's chat all read it, instead of each combining the flags.

* fix(native-chat): Stopping holds until the stopped turn ends, whatever the Stop's answer

A Stop the agent declined, or whose end went unconfirmed, used to drop the chat
back to Working. It now stays on Stopping until the turn ends, and Stop stays
enabled so a repeat press escalates. The Stop's answer is no longer read for
Stopping, so its note goes back to the key the base gives it (the restore of
queued-stop.ts and the removed key test landed in the previous commit). The
note still keeps a press that took over a later refusal, and a failed process
end still says the Stop went unconfirmed.

* fix(native-chat): a Stop binds only the turn it actually stopped

A Stop pressed before any turn showed used to claim, at end-write time,
whatever turn the stopped send later opened, even when the Stop stopped
nothing. A turn that then died on its own read as "Interrupted" (your
cancellation) instead of "Failed".

Now a person's Stop that named no turn binds, in memory only, every turn
that ends while the Stop settles, and afterwards only the turn its
interrupt took. The settle ends a still-running stopped turn once. A
relaunch finds nothing in memory, so an unsettled turnless Stop binds no
turn. A Codex Stop whose answered turn does not open within its wait, or
whose send's answer was lost, now answers refused, so the host ends the
child and the turn can never run.

* fix(native-chat): keep the person's queue pause and close binding after a Stop settles

A host stop or eviction with no turn running now defers to a person's
Stop while its queue pause still holds with nothing sent since, read from
rows, so a held card is not handed off on reopen after a Stop that did
nothing or whose kill failed.

A person's close that named no turn opens a settle around its child's
end, so a turn that end cuts reads as theirs.

A press opens its settle only when the latest Stop event is its own or
the one in force it repeats: a late Stop, a card's interrupt or a lost
event row reopens no earlier Stop.

A Codex Stop that cannot reach a turn still able to open says the Stop is
unconfirmed rather than that no turn ran, and a second Stop still reaches
a turn an earlier wait left unopened.

Also drops the unused openedBy plumbing and the unreachable "a written
cancellation stays one" rule, and pins a relaunch after a named Stop.

* fix(native-chat): keep a failed Stop's turn display-only, and settle edges off the commit path

A Stop that failed marks the turn it could not stop for "Stopping…" only
(JournalStopSettle.failedOn): no turn-end rule reads it, so that turn's
own end with no verdict reads as a failure, not the person's.

A settle edge writes no row, so it no longer goes through the journal's
commit listener, which also delivers history, counts as activity for the
idle sweep and schedules the queue drain. A narrow settle-edge hook
republishes the status row and wakes the steer hold's handover, and
nothing else.

* fix(native-chat): a Codex Stop agrees on both presses when a turn is still owed, and pin the close's settle

A Codex Stop that waited for a turn Codex answered a send into now answers
"may still open" whenever that turn neither opened nor ended and its send
is still owed, however the wait ended (it ran out, or the thread went
idle). Before, a first press after an idle thread said no turn was
running and kept Codex, while an identical second press ended it.

Adds a test that a person's close the conversation outlives (as /clear
does) closes its settle, so a later turn that ends on its own reads as a
failure.

* fix(native-chat): a Stop that failed before its turn showed still reads Stopping through that turn

A Stop that failed with no turn open marked nothing, so the chat dropped
to Working and the turn that then opened never read "Stopping…". The
display-only mark now also covers that case: the first turn that opens
after the Stop failed, provided no message was handed to the agent in
between. No turn-end rule reads the mark, so that turn's own end with no
verdict still reads as a failure.

* test(native-chat): a Stop whose event row failed binds no turn to an earlier Stop

With one ordered journal writer the Stop's event is in the fold when its
write returns, so the press reads whether it owns the latest Stop from the
fold instead of awaiting the write. Pins the case the read must refuse.

* test(native-chat): name the settle, not a stream drain, in the Stop's own-end test

* test(native-chat): a Codex Stop answered before Codex ends the turn reads interrupted throughout

Codex answers an interrupt it took before it sends turn/completed (interrupted):
on TurnAborted the app-server answers pending interrupts, then ends the turn, on
one channel. The test fake did the reverse. It now answers first and ends the
turn on a later read, and the tests that read the turn's end right after a Stop
wait for it.

New end-to-end test through the shipped host, journal and Codex adapter: with
the real order, every end row of the stopped turn reads interrupted by the Stop
(named, unnamed, and a Stop pressed while turn/start was in flight). Breaking the
settle window turns the in-flight case red: the Stop's own end row then has no
verdict, which reads as failed until Codex's end lands.

* test(native-chat): Stopping ends with a Codex turn whose interrupt is answered before its end

With Codex's real order (the interrupt's answer, then turn/completed interrupted),
the status shows Stopping while the Stop settles, drops it once the turn ends, and
never carries a verdict other than the person's cancellation.

* fix(native-chat): a Codex Stop interrupts a turn Codex answered but has not opened at once

A Stop that named no turn, made after Codex answered a send but before the turn
opened, used to wait up to 5 s for the turn to open before interrupting, and
ended the Codex process when it didn't. The stated reason, that Codex refuses an
interrupt until it opens the turn, holds only part of the time: with no turn
active, Codex takes an interrupt once its thread runs (turn_interrupt_inner),
and refuses it with -32600 "no active turn to interrupt" before that or once
the turn has ended.

The Stop now sends the interrupt at once. Only on that refusal, while the turn
has neither opened nor ended, does it wait for the turn to open (bounded at
5 s) and send it once more. A turn that ended meanwhile was nothing to stop. One
that never opens, or that an earlier wait already gave up on, fails the Stop,
and the host ends the child as before. Sends still wait for the turn to open
before steering into it.

The test fake models Codex taking an interrupt once the thread runs (run()).

* fix(mobile): name how the phone's status stream is released in the subscription inventory

Main made each inventory entry state its release; the status feed's stream is
released from its subscribe params, as the session event stream is.

* fix(native-chat): every Codex Stop waits for an answered turn to start, as the first did

A Stop whose interrupt Codex refused as finding no active turn skipped the wait
when an earlier wait, a Stop's or a send's, had already given up on that turn.
Every press now waits its own bound and retries once if the turn starts, so a
turn that opens during a later press is still stopped. Both presses still reach
the same verdict when it never starts.

* fix(codex): never steer a turn whose interrupt Codex answered

Codex answers an interrupt as the turn aborts, before it sends that turn's
turn/completed. In that gap the adapter still counted the turn as running, so a
message handed over right after a Stop settled (the Stop's own end row already
reads the turn ended) went out as turn/steer, which Codex refused with -32600
"no active turn to steer", and only then as turn/start. The adapter now marks a
turn whose interrupt Codex answered as aborted until its turn/completed, never
steers into it, and starts the message's own turn directly. Steering a turn
that is genuinely running is unchanged.

* fix(native-chat): a message sent while Stopping is queued as a card, whatever the setting

While the chat reads Stopping (the host's flag or this client's own Stop in
flight) there is no turn left to steer into, so the desktop asks the host to
queue the send even with the queueing setting off, and it is never drawn as a
bubble inside the turn being stopped. The phone already queued every send on a
capable host; a test now pins that it does so while Stopping.

* fix(native-chat): a message queued while Stopping is a card at once, not after the stop

A person's Stop holds the session's lane until Codex answers its interrupt, and
a send was admitted only behind it. By then the turn read ended, so a send that
asked to be queued went out plain: no card for the whole of Stopping, then a
bubble and a new turn.

While the host reads that a person's Stop is ending the work, a text send that
asks to be queued is admitted without waiting for the lane: the same ledger and
lease admission, and a plan that only writes the card through the journal's
ordered writer. The card runs when the stop lands; the Stop's pause holds only
cards queued before it. Anything else, including a Stop that settled by the
time the send runs, takes the lane as before.

The Codex test fake now drops the active turn when it takes an interrupt, as
Codex does before it answers, so a turn/start after the answer opens a new turn.

* fix(native-chat): a Codex Stop that ends the child before any turn opened withdraws its send

A Stop on a Codex turn that was answered but never opened ends the Codex
process. That end settled the send as in doubt (unknown, recovered), and the
client's outbox holds every later send behind a send in doubt until the person
presses Retry, which re-sends the very message they stopped. The chat looked
stuck.

Codex records a prompt only once its turn has started, so a send whose turn
never opened never ran. When the Stop's refusal says so (turnMayOpen), the child
end now settles the unanswered sends as withdrawn, the verdict Codex's own
interrupted-turn end already gives an unechoed send. The flag rides on the owed
wind-down, so a retry after a failed child end withdraws them too. Claude's
child end still leaves its unanswered send in doubt.

* fix(native-chat): derive the withdrawal of a Codex send whose turn never opened

Replaces the flag the Stop carried to the child's end, and its copy on the owed
wind-down, with a reading of the journal at the settlement that lands. A Codex
child's unanswered send is withdrawn when a person's Stop is in force since it
was sent and no turn row ran, or was written, after it; any other end (a turn
that opened, a host's close, a crash, Claude) still leaves it in doubt. A
retried wind-down reads the same rows, so it withdraws the same sends.

* fix(native-chat): a card queued while Stopping runs past the cards the Stop holds

A card queued before a person's Stop waits under its pause until Resume. One
queued after it, as a message sent while Stopping now is, was stuck behind them
too, since the queue never reorders. Such a card was asked for after the Stop,
so it runs when the stop lands, past the cards held only by that Stop's pause;
a returned card and the restart and /clear pauses still hold everything behind
them.

Also: the host's own Stopping reading is gated on working, as the published
flag is, so a failed Stop's mark never reads Stopping on an idle session; a send
that falls back to the lane re-reads the conversation's journal there; and the
end-to-end test asserts the queue's pause rather than a per-card field.

* fix(native-chat): a paused queue labels only the cards it holds

Since a card queued after a person's Stop runs past the cards the Stop holds,
labelling every card "paused" while the queue's pause is published misreads that
card. The host now marks each card its pause holds (heldByPause, a new optional
field), and the desktop and phone label only those. An older host marks none,
so a client keeps today's labels; an older client ignores the field.

Adds a test of the desktop's own send through the real outbox: while the chat
reads Stopping, the request asks the host to queue it and no bubble is drawn,
on a host that advertises the queue.

* revert(native-chat): defer the per-card queue pause label to the queue's rollout

The heldByPause field and its labels are visible only where the host
advertises the queued-messages capability, which shipped hosts do not yet do.
Deferred to that rollout; the real-outbox send test stays.

* fix(native-chat): while Stopping, say and show what a send does where the queue is dark

Shipped hosts do not advertise the queued-messages capability, so a message
sent while Stopping goes out plain: the host holds it until the stopped turn
ends and then runs it as its own turn. The composer still said "Queue a message
to run after the stop", and the message was drawn inside the turn being
stopped.

Now the placeholder reads "Send a message to run after the stop" where the host
does not queue sends, and "Queue a message…" only where it does (desktop and
phone, all six catalogs). A send this client made that the host has not
recorded yet is drawn after the Stopping line while the chat reads Stopping, as
a message held behind a running command already is; once the host hands it
over it opens its own turn. Client presentation only.

* fix(native-chat): keep a send in doubt when a turn was open for it

The derived withdrawal read a turn as open for a send only if it still ran or
was written after the send. A send steered into a running Codex turn whose
interrupt failed met neither once the adapter's end settled that turn ahead of
the host's settle, so it read withdrawn, though Codex drains a steer into the
running turn and may hold it. A turn that ended after the send was handed over
was open for it too: such a send stays in doubt, as before.

Pins that case, and that a send made after the Stop, to a child that then dies
before its turn opens, stays in doubt.

* fix(native-chat): restore the per-card queue pause label

Kept after all: a paused queue labels only the cards it holds (heldByPause),
which is visible only where the host advertises the queued-messages capability.

* fix(native-chat): draw only a send made while Stopping after the Stopping line

Every send the host had not recorded yet was drawn after the Stopping line,
including one made just before the Stop, which the host steers into the turn;
it then jumped up into that turn once recorded. The outbox now marks a send
made while the chat reads Stopping, and only those wait after the line.

* fix(native-chat): withdraw a Codex send by whether it started its own turn, not by timing

Whether a turn was open for a send was read from end times: a turn that ended
after the send's handover counted. A send made while a Stop ended the turn is
handed over once that turn reads ended, yet Codex's own end for it can arrive
later, so such a send whose own turn never opened read in doubt again, and the
chat's queue held behind it.

The handover already records where the send went: its message joins the turn
running then (a steer) or belongs to no turn (it starts its own). Only a send
that started its own turn, with none opened since, is withdrawn; one that
joined a running turn, or has no recorded place, stays in doubt.

The Codex test fake takes an answered interrupt as Codex does, dropping the
turn before its end arrives.

* refactor(native-chat): move queue-while-stopping to its own follow-up

The queued-messages capability is off on every shipped host (#21062), so the
parts of this PR that act only when it is on move to a follow-up stacked on
this one: admitting a queued card while a Stop holds the session's lane, a card
queued after a Stop running past the cards it holds, the per-card pause mark,
and asking the host to queue a send made while Stopping. This PR keeps the
Stopping state, the host's steer hold, the rule that never steers a turn whose
interrupt Codex answered, and what a send while Stopping looks like where the
queue is off.

* fix(native-chat): leave no Stop row when the Stop took back a send that never ran

A Stop on a Codex send whose turn never opened ends the child, and the child's end
takes the send back into the composer. The Stop still wrote "Cancellation
requested." at the conversation level, so with the send gone it sat under the
previous finished turn and read as if that turn had been stopped. A Stop that found
no turn running and whose child end took back every send it found now writes no
row; a Stop of a running turn, or one that leaves a send in doubt, still does.

* fix(native-chat): count a send whose answer was lost when a Stop takes it back

The no-row rule counted only pending sends, but the child's end also takes back a send this process left in doubt when Codex's turn/start answer was lost. That case still wrote "Cancellation requested." under the previous turn. Both now read one predicate, so they cannot drift apart.

* test(native-chat): pin which sends a Stop's child end can take back

A send an earlier process left in doubt is never withdrawn and never holds the row back, and a queued card's send is never counted.

* fix(native-chat): read the host's Stopping beside main's startup phase

Main now reads only the startup phase from the status feed and no longer publishes which
child is starting. The chat reads the host's Stopping from its own hook beside it, and the
Stopping bridge test mocks the execution-host lookup main's owner resolution now calls.

* test(native-chat): read the outbox reconcile from where main moved it

* fix(native-chat): a retried message no longer waits behind a later Stop

Retry dropped the Stop it had outlived but kept the mark that it was sent while
a Stop was ending a turn, so a retried message waited behind whatever later,
unrelated turn a Stop was ending. Retry is a new send: drop that mark too.

* fix(native-chat): word a send after a Stop by whether this send will queue

The 'queue a message to run after the stop' placeholder read the host's
queue capability alone. A send queues only when the host queues and this
send asks it to: the queue setting is on and no pending prompt blocks the
queue. Desktop and phone now word the placeholder from that same decision
their send uses.

* test(native-chat): one test per case for the words of a send after a Stop

* refactor(native-chat): the dictation hook owns the composer's dictation state

Keeps NativeChatComposer within its line limit after the Stop props and
main's /context answer both landed in it.

* refactor(native-chat): name the dictation hook for what it owns now

* fix(native-chat): a Stop's note says it took once a joined close proves the exit

A session-ending Stop whose child's end failed revises its note to
'unconfirmed'. Since main's #24862, the next Stop joins that close rather
than stopping again, and wrote no note, so a close that then proved the
exit left 'unconfirmed' under a turn that ended. The close now carries
the note it settles, and its proven exit revises it to 'Cancellation
requested.'. A join that fails again leaves it unconfirmed.

* fix(native-chat): a proven turn end says a Stop's unconfirmed note took

Replaces the note carried on the child's close. Every settlement that
ends turns interrupted on a proven exit, live or after a crash, also
revises an unconfirmed Stop note on those turns to 'Cancellation
requested.', found by the note's turn scope, in the same batch. A note a
Stop wrote before its turn showed is re-keyed onto the running turn when
it becomes unconfirmed, in one batch, so that end finds it. Known limit:
with no turn open yet, the note keeps its key and no turn's end revises
it.

* test(native-chat): a Stop's unconfirmed note says it took when the agent exits on its own

* test(native-chat): name the Codex handle as main's opaque handle does

* test: restore the provider handle import the main merge dropped

* fix: derive Stop note wording from interrupted turns

* test: name the raw replay case for what it covers

* refactor(native-chat): move the waiting-slot split into its own hook

* test: follow main's chat font-size rename in the stopping tests

* test: follow main's single live-line value in the Stopping tests

* test: give the android live-line fixtures the stopping field

* chore: keep the session host under its line limit after the main merge

* chore: keep the composer test and the phone chat view under their line limits after the main merge

The Stop control now disables itself while Stopping, so the composer passes
the flag through and its test file stays as main has it. The phone chat
header's Stop moves to its own component.

* perf(native-chat): read a Stop note's fields before parsing its key on every snapshot

Every snapshot projects each item through the Stop-note read, and each new
snapshot rebuilds the index of Stop notes by turn. Both parsed every item's
key first; they now check the row's kind and turn scope (and, for the
projection, its unconfirmed-stop failure) before the parse. Every Stop note
is a status row, so what each finds is unchanged.

Subject: [PATCH 143/167] fix(ci): restore main's typecheck and lint after
 #25751 and #24369 (#25949)

A test still called isStructuredAgentSessionThinking with a bare array after
#25751 changed it to take { items }, and #24369 left the session host one line
over its max-lines budget. Both fail CI on every PR.

Subject: [PATCH 144/167] feat(native-chat): attach several files from one
 picker selection (#23956)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* feat(native-chat): attach several files from one picker selection

Picks over 256 files are rejected whole, matching the drop limit.

Fixes #23905

* refactor(native-chat): name the composer action for the files it now attaches

The hook still returned `pickAttachment` after it started attaching a
whole selection. Also records why the plural IPC handler sits next to the
singular one, matching its siblings in the same file.

* test(native-chat): cover the paperclip forwarding every picked path

The one line that makes the feature work — the composer handing the whole
picker result to attachExternalPaths — had no test; reverting it to
paths[0] kept every existing test green. Adds a hook test for the
multi-path, canceled, and wrong-pane cases, plus the missing canceled
case for the shell:pickAttachments handler.

* test(native-chat): exercise multi-pick through renderHook

* test(settings): preserve label fallback and verify Spanish copy

Keep latest main's missing-label fixture and restore its translation namespace after cleanup, so later tests still load real catalogs. Independently assert the shipped Spanish resource and rendered supported-agents label.

Subject: [PATCH 145/167] fix(native-chat): say each chat outcome once and drop
 internal-only surfaces (#24595)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* fix(native-chat): say each chat outcome once and drop internal-only surfaces

After a restart, resuming a chat reported the same outcome in up to four
places: a toast, the chat's own note, the status bar entry and the resume
dialog. Success also toasted, and a lost answer or unconfirmed dismissal
raised toasts of their own. The chat's note and the status bar entry (which
opens the dialog listing every affected chat) now carry it alone, and the
resume guidance no longer talks about which process "owns this session".

Provider events Orca does not recognise and that carry no words of their own
are logged instead of journaled as raw "codex · notification:foo" rows. Rows
with the provider's own sentence, failures, and records of replies Orca
already sent stay.

The approval card no longer shows the matched ask rule, its settings source
or a "Blocked path" line; it keeps the request, its detail and the reason.

* fix(native-chat): store wordless provider events, hide them only when drawn

Dropping text-less provider events on the host also dropped Codex's
turn/plan/updated row, which the task list (checklist and composer progress
panel) is built from. The host now journals these rows exactly as before,
and desktop and mobile chats leave out a row whose only text is the host's
"provider · kind" label. Failures, notices, rows with the provider's own
sentence and records of requests Orca answered still show. A hidden legacy
Codex collab-call row still counts as the agent acting for which subagent
section stays open.

Claude's local slash command output is read from `content` for that one
event kind only, so it shows as the row's text instead of disappearing.

* fix(native-chat): rows no client draws never fill the Codex cap or split a turn's work

- Codex per-turn cap: a wordless provider row (decided by the same shared rule the clients use)
  has its own silent storage bound, so it no longer crowds out rows that draw and never produces
  a "N more provider notifications not shown" line about rows nobody sees. Plan updates are
  exempt from the cap, so the task list keeps updating after a noisy turn.
- A Claude local command's row an older host stored with only its label (/usage output in the
  payload) stays drawn instead of disappearing.
- A settled turn whose only extra row draws nothing offers no expand arrow, and a wordless row no
  longer splits one tool run into two.

* fix(native-chat): a resume request that never reached the chats says so once, with Retry

When the resume request fails before the host reserved anything (the host is not ready, or its
recovery record cannot be written), the host has nothing to record, and the chats used to fall
silently back to "N chats to resume". The status bar and dialog now show them as failed, with the
existing guidance and Retry, until Retry, Dismiss, a host answer that no longer offers them, or a
relaunch. Comments that still cited the removed toast are corrected.

* fix(native-chat): keep mobile tool runs whole and a failed Dismiss's chat marked

- Mobile draws no task list, so it now drops wordless provider rows, plan updates included,
  before folding tool runs; a mid-run plan update no longer leaves two run headers back to back.
- A Dismiss the host never took keeps a lost resume request's chat shown as failed instead of
  turning it back into a plain offer. The lost request's real error now goes to the renderer log,
  since the row carries this side's own reason code.
- Comments corrected: the Codex cap no longer claims dropped wordless rows stay countable, and
  the resume comments cover a chat a lost request never reached.

* fix(native-chat): tell the user what their Resume click did, in one toast

Clicking Resume in the dialog (or Retry on a row) closes the dialog and acts on
chats that are mostly off-screen, and nothing said what happened. One toast now
summarises that click: "Resumed N chats and asked them to continue", "N chats
couldn't be resumed" with Show (opens the dialog), "Couldn't confirm N chats were
resumed", or the mixed case in the same toast. A request lost before it reached
the chats counts its chats as not resumed. An opted-in automatic resume at launch
raises no toast; dismissal and other bookkeeping stay silent.

* fix(native-chat): Show on the Resume toast re-reads before opening; fix toast translations

Show could open nothing when the host retired the failure while the toast was up,
because the dialog draws nothing without rows and the request stayed latched. Show now
goes through the status bar entry's re-read-then-open path, moved into the store so
both use it. The French, Japanese, Korean and Chinese "Resumed N chats and asked them
to continue" strings are rewritten to match their sibling strings. Tests pin Show on
the toast of a lost resume request whose chats the re-read still lists.

* test(native-chat): click the Resume toast's Show through a typed helper

The tests reached sonner's action handler with Reflect.apply, which the anti-slop lint
rejects. One test-support helper now returns the last toast's Show as a typed click.

* fix(native-chat): name the path an approval needs when the request doesn't show it

The approval card dropped Claude's blocked path along with the ask rule, so a
request like `git push` that needs access to `.git/config` no longer said what
it touches. Bring the path back as "Needs access to: <path>", only when the
description, reason or request detail doesn't already show it (verbatim or
JSON-escaped). One shared rule serves desktop and mobile; the ask rule stays out.

* fix(native-chat): count a blocked path as shown only when the text names the whole path

'/srv/data' inside '/srv/data-old/x' hid the "Needs access to" line although
the path itself was never shown. A match now needs the next character to end
the path: end of text, whitespace, a quote or a separator. Also pin that the
desktop approval mapping passes the blocked path through and drops the ask rule.

* fix(native-chat): the automatic resume at launch gets the same one outcome toast as a click

An opted-in launch resume now calls the same announce as a clicked Resume, with the same copy:
how many resumed, how many couldn't (with Show), unconfirmed, or mixed, said once. Dismiss and
bookkeeping stay silent; a launch whose chats all moved on raises nothing.

* fix(native-chat): the resume success toast says "Resumed N chats"

Each chat's own note already says Orca asked it to continue, so the toast drops "and asked
it/them to continue" in every locale; the couldn't-resume and couldn't-confirm counts and Show
are unchanged.

Subject: [PATCH 146/167] fix(remote-browser): host client browser pages again
 when a paired host comes back after an outage (#25827)

* test(remote-browser): reproduce a client-hosted browser tab left unavailable after a network outage

A paired desktop that loses its host for longer than the browser-host
lease grace (25s reset cut, or a 100s silent cut the host's heartbeat
reaps) tears down its client-hosted pages and never hosts them again,
leaving 'Client-hosted browser unavailable'. Red on main.

Extends the freezable TCP proxy with a full silent or reset link cut.

* fix(remote-browser): host client browser pages again when a paired host comes back after an outage

When the network between a paired desktop and its Orca host dropped for longer
than the browser-host lease grace, the desktop tore down its client-hosted
pages and never offered to host them again, so the tab stayed on 'Client-hosted
browser unavailable' until the app was relaunched.

Regaining contact with a runtime now re-claims browser hosting the same way a
runtime restart already did: if this desktop still has client-placed pages for
that host, it starts its browser client host again and the host's existing
recovery re-places them, reloading at their last URL. The notice now says the
host is offline (and that the page reloads when it reconnects), names another
desktop only when the placement belongs to one, and otherwise says the page is
not available here right now.

* fix(remote-browser): claim offline only for a host that can reconnect, and re-host from the notice

The unavailable notice said the host was offline for any null status, which
also covers a retired or refused pairing and a host whose runtime did not
answer. It now uses the host connection state and excludes revoked verdicts.

When the control link returns while the old browser host is still inside its
lease reconnect, the contact-edge ensure is a no-op; if that reconnect then
fails, nothing re-hosts. The notice now re-claims hosting on mount while the
host is reachable, which is exactly that stranded state.

Plain regained contact no longer queues a second preparation behind one
already in flight; only a runtime restart does.

* fix(remote-browser): re-prepare browser hosting on every regained contact

A preparation still in flight when contact returns started while the host
was unreachable, so it is the one most likely to fail. Coalescing the
contact edge into it dropped the only trigger that could succeed and left
the page unavailable. Always queue one follow-up preparation instead.

Subject: [PATCH 148/167] fix(codex): write Orca's hook into ~/.codex only when
 something changed (#25743)

* fix(codex): write Orca's hook in ~/.codex only when something changed

One reconcile replaces the per-launch writer and its background approval
session. It runs at app start after PATH hydration, when the setting turns on,
once per native pane spawn, and (with a bounded 3 s wait) on Codex launches and
resumes. Orca's entry lives alone in a matcherless group, appended last unless
already in place; other copies are removed and the shifted user approvals move
verbatim under both key spellings. The approval, with Codex's own hash, goes in
first. The routing gate closes only for a hooks.json with a bad shape.

* fix(codex): report hook status for the home the next pane uses

Status reads ~/.codex (both key spellings) when launches use it, or the CLI
has no selection, and the selected managed home otherwise. It explains: update
Codex, Codex not found, not asked yet, approved by Orca but not yet confirmed
by Codex, a hooks.json shape that moves panes to Orca's own home, and inline
config.toml approvals Orca cannot add to.

* test(codex): pin the ~/.codex approval against a real Codex, and run it on those files

The contract now also writes Orca's entry into a throwaway ~/.codex and checks
that Codex lists it trusted and enabled, turns it back on over a /hooks
switch-off, lists it for review after a user inserts a hook ahead until the next
check, keeps an inline config.toml loadable, and shows no review in a real TUI
start. The real-binary CI job now runs when the ~/.codex writer changes.

* test(ci): keep the scope test under its line cap; assert the ~/.codex paths beside the contract job

* test(codex): type the hoisted test holders instead of asserting

* test(codex): cover the matcher rule, an older build's event, and the spawn trigger

Adds tests that failed against mutants which survived the first pass: an
entry alone in a matcher group, a current copy's approval in an event left to
an older build, one run per spawn, a spawn riding a running reconcile, and the
native-only spawn trigger. The opt-out's Codex-hash cleanup now runs once,
after the sweep, instead of twice.

* docs(codex): name the ~/.codex reconcile in the legacy sweep's lane comment

* fix(codex): approve ~/.codex with Orca's own hash while Codex's answer is pending

The reconcile waits at most 0.5 s for Codex's hash. If the lookup is still
running, an entry already in place keeps its approval and nothing is written;
a missing entry or approval gets Orca's computed hash, approval first, inside a
launch's 3 s wait, as main's did. When the lookup lands, the reconcile runs
again and Codex's hash replaces it.

* refactor(codex): one start for the hook lookup and the ~/.codex reconcile

startCodexHooks replaces the two start functions and takes the PATH wait that
the reconcile request's after option carried. A spawn reconciles unless one is
running, without a scheduled flag, launches call one reconcileCodexHooksForLaunch
on the shared withTimeout, and the reconcile alone reads the hooks setting. The
startup test now runs the ready phase instead of matching its source text.

* refactor(codex): plan ~/.codex with the shared Orca-hook pruner and approval reader

The planner prunes with removeManagedCommands, as the opt-out does (so a hook
that runs Orca's script through its args goes too), and returns a prune or
settle union. While Codex has not answered, the kept approval comes from the
shared per-event reader. The reconcile result is its outcome alone, a
concurrent save spends a pass of the one bound, the opt-out removes Orca's
approvals once, the approval-first writer takes the hooks path, and
getRealHomeConfigTomlPath gives way to getSystemCodexConfigTomlPath.

* fix(codex): ~/.codex keeps only an approval holding a hash Orca's entry may carry

* refactor(codex): name the ~/.codex hooks-file check for what it reports

* test(codex): the ~/.codex entry tests know Codex's earlier hashes, as the app's lookup does

* refactor(codex): the ~/.codex reconcile uses the lookup's answer names

* test(codex): ~/.codex status tests keep a Codex on PATH unless one is missing

* refactor(codex): one stopgap for both homes; the ~/.codex pass finds its own home, hash and user data

Also passes every approval to the approval-first writer, which already skips the ones in place.

* refactor(codex): the reconcile start owns the warm-up; no rerun-on-answer flag

The lookup start only records the hydrated PATH; one catch, one request type, and the app config is kept as given.

* refactor(codex): the ~/.codex pass returns nothing; tests read the files

Also makes the ~/.codex opt-out take Codex's hashes, as every production caller passes them.

* refactor(codex): the ~/.codex approval cleanup takes Codex's hashes

* test(startup): check the Codex hook start waits for PATH by behavior, not identity

* fix(codex): a status-hook problem never moves the system default off ~/.codex

* chore(ci): run the real-Codex contract when the ~/.codex reconcile changes

* docs(codex): the ~/.codex reconcile's refused branch covers every definitive refusal

* test(codex): start the failure-memo lookup with the reconcile's PATH-only start

* fix(codex): ~/.codex gets nothing while Codex is missing, a pending answer uses the saved one, a conversion waits for a run that writes, and status and the reconcile read one home and one Orca-hash rule

* test(codex): ~/.codex and managed-home status tests name their home; ~/.codex rewrites the backslash key Codex on Windows reads

* test(codex): the Windows upgrade test reads status for the managed home it installs

* test(codex): the real-TUI contract trusts its workdir by its real path, and its userData exists

* fix(codex): keep Orca's approval at every slot its entry holds in ~/.codex

Subject: [PATCH 149/167] fix(repos): stop reporting clones that never ran as
 successful (#23770)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* fix(repos): reuse a saved project only when git shows it's this clone

A saved project outlived its folder, so Clone reported success without running git.

Fixes #23563

* fix(repos): let a repeat clone of an empty repository reuse its project

A clone of a repository with no commits leaves HEAD unborn, which
`rev-parse --verify HEAD` rejects exactly like the `refs/heads/.invalid`
HEAD a killed clone leaves. The saved-project check read both as "not a
finished clone", so cloning a brand-new empty repo a second time — a
double-clicked Clone, a re-run `orca project setup-clone`, or #2981's
queued retry — fell through to git and died on "destination path already
exists and is not an empty directory".

Ask the two questions apart when `--verify` fails: `symbolic-ref HEAD`
resolves an unborn branch but not a killed clone's HEAD. It is already on
the relay's read-only allowlist. Probes also short-circuit once the clone
is cancelled, so no probe after Cancel spawns git.

* fix(repos): prepare the worktree root after re-cloning a project's folder

The branch that re-clones into a saved project's folder returned the
project without the two steps every sibling branch runs: the worktree
root that vanished with the deleted folder is never re-created, and the
authorized-roots cache keeps the answers it cached while the folder was
missing. Creating a worktree or reading files in the recovered project
then fails on a root that is not there.

* fix(ssh): register the root after re-cloning a saved project's folder

`addRemoteRepoFromPath` returns an existing project before it notifies
`session.registerRoot`, which was unreachable before the saved-project
check could re-clone into a project's own path. The relay therefore never
learned the folder came back, so sessions under it stayed unregistered.
Notify from the clone, mirroring the folder-to-git upgrade beside it.

* fix(repos): say which reason refused a clone over a saved project

One message covered both "that project holds a different repository" and
"Orca has no record of what that project held", which need different
things from the user. Name the recorded URL when there is one, and say
plainly that there is no record when there isn't — the second is the case
a project predating remote-identity enrichment lands in, and the user
cannot act on it without being told why.

Also drops the `upstream` remote-name check into a named binding: `origin`
is the only stored remote that names a project's own repo, because
`Repo.upstream` and the GitHub avatar derived from it both name the repo a
fork came from.

* fix(repos): bound saved-clone probes and prove empty clone completion

* fix(repos): keep clone validation host-scoped and locale independent

Subject: [PATCH 150/167] perf(ci): compile release JavaScript once for all
 packaging hosts (#25828)

* perf(ci): share release JavaScript across packaging hosts

* fix(ci): verify the projected web entry in release archives

* fix(ci): use the Windows system archive tool for release bundles

* test(ci): retain stylesheet evidence in release build comparisons

* test(ci): verify release parity across native color rounding

* test(ci): normalize manifest asset references without changing import order

* test(ci): compare portable outputs across Windows text and color formatting

* test(ci): preserve module identity across dependent asset hashes

* fix(ci): keep SVG build inputs identical across release hosts

* fix(ci): stabilize compiler inputs and projected web bindings

* fix(ci): retain vendor minification in projected web output

* test(ci): normalize platform-specific pnpm manifest source paths

* fix(packaging): exclude shared build staging from application files

* test: align thinking-state fixtures with the current source shape

* test(mobile): reuse message fixtures within the line limit

Subject: [PATCH 151/167] refactor(codex): remove code the ~/.codex hook rework
 left unused (#25744)

* refactor(codex): remove trust-grant code the ~/.codex reconcile left unused

* refactor(codex): remove the native trust-grant host only tests reached

Only WSL runs a grant session, so resolveNativeCodexTrustGrantHost, its
timeout, the native host arm and buildNativeCodexBinaryStamp go. The ledger
still parses a native stamp, so files an older build wrote keep loading. The
grant suites now run on a WSL host with the guest probe stubbed.

* docs(codex): name the live caller in the envToDelete comment

* refactor(codex): the trust-grant host key and telemetry lane name the one host left

Only WSL reaches the grant, always on the managed lane; the telemetry event keeps its shape.

* refactor(codex): remove the unwired real-home lane gate

* docs(codex): the trust-grant telemetry comment names the one surface that still grants

Subject: [PATCH 152/167] fix: recover deleted Active Server defaults and
 preserve editor hosts (#25938)

Repair deleted Active Server defaults through validated registry reads and existing settings notifications. Capture editor ownership from backing files so workspace focus cannot redirect file operations.

Correct two live-turn test fixture calls to the current API.

Refs #21489. Historical session recovery remains separate work.

Subject: [PATCH 156/167] Keep profile saving alive after a stalled main loop
 (#25318)

* Keep profile saving alive after a stalled main loop

After a long main-loop stall (overnight sleep, dark wakes), the profile
writer's overdue 30s timeout could run before an acknowledgement that was
already queued, permanently retiring the writer until restart. Terminal
creation then failed because pane bindings could not be saved.

- Writer deadlines measure lateness on the monotonic clock and grant a
  bounded fresh window when the callback is overdue or the system reports
  suspended; resume re-arms without spending grace. Applies to
  initialization, every command, and the close/exit wait.
- The "Saving stopped" alert is parented to a visible main window (never a
  parentless synchronous macOS alert), deferred until shown, deduplicated,
  and says whether the latest change is unconfirmed.
- Timeouts, grace, writer faults, and alert presentation leave sanitized
  durable breadcrumbs.

* Fix profile writer timeout and shutdown races

* Run profile writer stall regression on Linux and Windows

* Keep Electron probes out of headless runtime qualification

Subject: [PATCH 157/167] fix(terminal): keep a pane closed just before quit
 from coming back on relaunch (#25711)

* fix(terminal): keep a pane closed just before quit from coming back on relaunch

The daemon now lists a session whose kill it accepted as state 'exiting' (still
live), the inventory carries that through to pty:listSessions, and the
worktree activation gate never adopts an exiting PTY into a new tab.

Co-Authored-By: Claude <noreply@anthropic.com>

* test(e2e): use the Linux close-pane chord (Ctrl+W) in the closed-pane relaunch spec

Subject: [PATCH 158/167] fix(native-chat): honor saved agent Command and
 Arguments (#25721)

* fix(native-chat): honor saved agent launch commands and arguments

* fix(test): retain provider import after syncing main

* fix(native-chat): preserve launch arguments and explain invalid settings

* refactor(native-chat): require the current launch arguments source

* fix(native-chat): require saved arguments when installing the runtime

* fix(native-chat): show saved argument refusals beside launch retry

* fix: ship saved-argument error messages in every locale

* test: align model discovery with executable overrides

* chore: drop the local pnpm install lockfile block

Subject: [PATCH 159/167] feat(agent-launch): host-assigned caller identity and
 a launch record written when the surface exists (#24934)

Step 1 of the agent-launch unification, on main.

- The dispatcher stamps every request's caller from what its connection proved (runtime socket:
  the local CLI; the desktop's IPC: the desktop; a paired socket: its device). Params never set it.
- The launch record is written twice: once when the tab exists (what creation settled: on the
  launch command, a draft, or a submit still `unconfirmed`), and again once the prompt's fate is
  known. A restart in between finds the running agent instead of answering "unknown".
- A replay re-derives its terminal handle from the pane key in the running host, and shows
  `unconfirmed` only to callers that advertise agent.launch.prompt-unconfirmed.v1.
- The record store opens in its own slot, without building the chat host; the chat host is built
  on that same store.

Rebuilt from this PR's own commits (b9adf88da04, 0d7d9b5b30e, c83f44dd724, 39d15d52c0f) onto
main, without #24080/#24081. Conflicts: the delivery doc table (main's "line fits" row plus the
`unconfirmed` row), and main's journal-database open in install(), which now goes through the
record-store slot.

Subject: [PATCH 161/167] feat(native-chat): keep a message a Stop took back on
 screen, with one stop row after it (#25051)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* refactor(native-chat): derive the queue's pause from Stop and Resume journal rows

Stop now appends one journal row where it takes effect, before the interrupt,
whatever the queue holds; Resume appends its own. The pause is a pure function
of the fold: the latest Stop with no later Resume and no later accepted turn a
person asked for. A /clear's carried cards name their source, which is the
replacement's 'cleared' pause. Host-origin turns never lift either.

One predicate decides which cards a pause holds; by default every waiting card
without a hold of its own, including one queued after the Stop. The drain's
consume re-judges it inside its own transaction.

The rows are tombstones of an id no item takes, carrying the mark: a released
host reads an unknown row kind as corruption and truncates the journal there.

Deletes the stored pause (recordPause, the retire hook on every appended row,
the settle-before-record step, mayReturnToWaiting and its row overlay) and the
tests that only proved it retires. The queued_message_pauses table stays in the
schema, unread and unwritten, for downgrade safety.

* fix(native-chat): a card queued after a Stop sends normally, never ahead of held ones

A Stop's pause now holds only the cards queued before its row, plus a steer it
withdrew, which returns to its own place. Each card records the journal
position it was queued at, and the one hold rule compares that with the Stop
row. A card queued after the Stop is a new instruction: it sends as usual, but
the drain still stops at the first held card, so it never overtakes them.
/clear's pause holds the cards it carried. Holding every card again is a
one-line switch in that rule.

* fix(native-chat): the queue's own send re-checks the no-overtake rule in its transaction

The drain's pick and its consume now read one function, nextSendableQueuedCard,
so a Stop row that lands between them holds a newer card behind an older held
one exactly as the pick would. Notes why Stop and Resume ride a tombstone row.

* fix(native-chat): stop creating the unused queue pause table

The queue's pause is derived from journal rows, so nothing reads or writes
queued_message_pauses. It was still created on every open "for downgrade
safety", but an older build creates it itself when it opens the database, so
the table only sat empty in every new database. The tests now pin that no
pause table exists.

* fix(native-chat): a Stop's pause never hides the restart pause

A Stop holds only the cards queued before it. The pause derivation still
returned the Stop alone whenever it was in force, so the restart pause was
never considered: a card queued after the Stop, written by a host process
that has since exited, sent by itself after Orca restarted, with no pause
header and no Resume. A /clear pause that held nothing could hide it the
same way.

Every pause in force is now derived. A card is held if any of them holds
it, and it names the first that does. The drain's pick, the consume
transaction's re-check and the published header all read that one rule;
the header names the pause holding the first card Resume would send.

* test(native-chat): pin the Stop's no-resend, lift and held-card rules

- The Claude and Codex Stop-withdraws-a-steer tests checked "not sent
  again" at one instant, before a queue ignoring the pause re-sends. They
  now wait for the stopped turn to end and re-check after a quiet window.
- The deleted-card test read a card queued after the Stop, which sends
  whether or not a person's turn lifts it; it now reads the Stop's pause
  before and after that turn.
- Unit cases pin that a Stop holds a card with no recorded position and one
  queued before a rewind.

* refactor(native-chat): a Stop writes one Stop event with its reason, turn and caller

The Stop row that paused the queue becomes the general Stop event
{ reason, turnId?, at, caller? }, whose reason is the host's existing stop
cause. It still rides a tombstone of a host-only id (a released host deletes
the journal from the first unknown row kind), and Resume keeps its own marker
on its own id. Only a person's Stop (reason user-stop) pauses the queue.

* test(native-chat): a rewind keeps a lifted /clear pause lifted and restates the same Stop event

* test(native-chat): pin that Stop and Resume rows never reach apps or count as history

* test(native-chat): only a person's Stop event pauses the queue

* test(native-chat): pin that a Stop's event precedes the interrupt and the at-start stop

Through the real host: the event names the turn and who asked and is in the
journal when the interrupt reaches the agent; at an agent still starting it is
there before the start is ended and holds a card queued before it; an idle Stop
writes one only when it withdrew a send; and the queue's claim re-judges a
pause that landed after its pick.

* test(native-chat): a card held at a starting agent is checked before the Stop's timing

Also says precisely what the claim's in-transaction pause check defends
against: the Stop and the drain share one serialized lane.

* test(native-chat): a released build keeps and folds a journal holding Stop events

Replays this build's rows from the released build's own journal database: every
row is kept, the history after the Stop still folds, and an older client is sent
only removed ids no item uses.

* style(native-chat): format the Stop event changes

* test(native-chat): type the released build's exports through one checked helper

* fix(native-chat): the Stop/Resume row guard narrows to those tombstones only

* test(native-chat): run the Stop-event downgrade test in CI, and cover a writable downgrade

The Stop-event downgrade test ran in no CI lane: unit shards exclude the
cross-version folder, and the cross-version lane runs a fixed file list that
did not name it. It is now on that list.

Its only case replayed the rows into a release's own fresh database, because
that release cannot open the current host database. A second case opens the
journal this build wrote with a main build that shares the database: it opens
writable, keeps every row, appends, and this build then reopens it with the
person's Stop still pausing the queue.

* fix(native-chat): a Stop that stops nothing new writes no Stop event

A Stop reaching a running agent wrote a Stop event on every press. Two
presses before the first interrupt landed wrote two events, so a card
queued between them counted as before the latest Stop and was held,
though a card queued after a Stop should send normally. A Stop naming a
turn that had already ended, as a phone sends late, also wrote an event
for a turn it never stopped.

It now writes one only when it withdrew a queued send, or stops something
no event records yet: not a turn the journal no longer runs, and not the
live turn a Stop still in force already names, unless a card was handed
over into it since, which this Stop's interrupt sends back and must hold.
The interrupt and the "already finished" note are unchanged. A Stop at a
starting agent still always writes.

* test(native-chat): pin that a later host, eviction or close Stop never lifts a person's Stop

* chore(native-chat): put each Stop-row doc on its own declaration, and say only user-stop is journaled

* fix(native-chat): any later Stop event ends a person's Stop pause

A person's Stop paused the queue until their next accepted turn or Resume,
and a later Stop of another reason (the host stopping the agent, an
eviction, a close) was ignored. Now the pause is the latest Stop event's:
a later Stop of any reason ends a person's pause, and only a person's Stop
pauses. The fold keeps the latest Stop event whatever its reason.

An eviction of a resting chat writes no Stop event (a Stop that stops
nothing writes nothing), so it cannot release held cards; a test pins that
no event means no lift.

* fix(native-chat): a second Stop press is a repeat even when the first came before the turn showed

A Stop pressed before the agent's turn shows in the journal (before
Claude's echo, or before Codex opens the turn) records no turn. A second
press once the turn showed compared that missing turn with the live one,
wrote a second Stop event, and held a card queued between the presses.

A repeat is now judged by what was sent since the Stop in force: with
nothing sent after it (a refused send aside), a Stop that named no turn,
or named the live one, is repeated and writes nothing. Anything sent since
and not refused, including a send whose fate is unknown, makes the new
press write, since its interrupt may send that card back to waiting.

Tests: the two-press case across the turn showing; a steer between the
presses settled unknown; and a Stop naming a turn that ended while the next
card is sent but shows no turn yet, which writes and holds that card. The
fold test that claimed an eviction path is renamed.

* fix(native-chat): the queue's pause ignores a Stop or Resume row holding a value no build writes

A Stop or Resume row's value is read from disk with no shape check, and
the pause fold stored whatever it found. A stored `stopEvent: null` would
then throw on every pause check for that chat: the queue's pick, its
send, and every queue update to clients. No build writes such a row, so
this is hardening.

The fold now reads a Stop only when it is an object with a string reason
and a finite time, and a Resume only when it is `true`. Anything else is
ignored: it pauses nothing and ends nothing. The row is still not treated
as malformed, which could cut the history short.

* fix(native-chat): a Stop still reads as yours after Orca restarts before the turn ends

Every stop that ends work now writes the Stop's event before it ends the child: a
person's close of the chat, an eviction (worktree teardown, orchestration stop, tab
cleanup) and the idle sweep's stop of a start that never landed. A stop that ends
nothing writes nothing, and quit writes none: its resume marker records why.

The turn-end write reads the latest Stop event where every turn row is built, so the
adapter's settle, the host's fallback and the relaunch's settle all agree: a turn a
person's Stop or close named, ending with no verdict of its own after that Stop, ends
as their cancellation. A relaunch's probe-bounded end is no earlier than a Stop that
found the turn running. When the provider refuses the interrupt and the turn runs on,
a refusal row answers the Stop, so a later crash still reads Failed; pressing Stop
again after a refusal is a new Stop.

* refactor(native-chat): a stop no longer carries its cause; the turn's end reads the Stop event

The cause of a stop was threaded in memory from each entry through the host's stop
step, the adapter router and each adapter's close onto the `ended` it settled with,
and Claude kept a per-turn copy of a Stop it sent. All of that is gone: adapters
settle a turn they cut as interrupted with no verdict, the host's fallback does the
same, and the one rule where a turn row is built (`turnEndAfterStop`) reads the
journal's latest Stop event to say whether it was a person's.

- `closeSession` / `disposeSession` take no cause; `ended` has no `stopCause`.
- Claude reads an error result after a person's Stop as their cancellation from the
  journal's Stop event (through the event sink), not from a per-turn slot, and a
  refused interrupt is the host's refusal row, not `withdrawTurnStop`.
- An owed wind-down keeps no cause: its retry's fallback reads the Stop event.
- The mutation context's Stop passes no cause: its step already wrote the event, and
  the delivery loop's child-end reason is read back from it.
- A Stop pressed before its turn showed applies to the turn that opens under it,
  unless a send a person made since was accepted.

* test(native-chat): a turn a later send opened is no Stop's that named no turn

* test(native-chat): the restart test's death proof carries its detail

* refactor(native-chat): a refused Stop leaves no record; a Stop only ever ends the turn it names

The stop-refused mark is gone: its tombstone kind, its fold, the clock-keyed match that tied it to
a Stop, and the exception that let a second press after a refusal write a new Stop. A Stop that
stops nothing writes nothing. A Codex refusal names a turn that is no longer its active one, and
the Stop names that turn, so the turn running instead never reads as the person's by its id alone.

* fix(native-chat): a Stop pressed before any turn showed stops only the turn opened next

A Stop that named no turn read as the person's cancellation for every later turn that opened
after it, until a send a person made was accepted. The queue's drain, orchestration mail and a
restart continuation send as the host, so a turn they opened long after, cut by a crash, read
"Interrupted" as if the person had stopped it. The Stop now applies only to the first turn
opened after it.

* fix(native-chat): an older Claude's error end after a Stop pressed before its echo reads Interrupted

Claude CLIs before 2.1.91 end an interrupted turn with an error result that names no reason. The
translator judged whether a person's Stop explained it by its own copy of the Stop rule, which
ignored a Stop that named no turn, so a Stop pressed before Claude echoed the send read "Failed".
The translator now writes such an end as interrupted with no verdict and no error row whenever a
person's Stop may name the turn, and the journal's one rule decides as it writes the end.

* fix(native-chat): a person's Stop and /clear each name why they end the agent

The host's mutation path ended the agent with one "recorded" ending for every caller, which read
back the reason of whatever Stop event the journal held last, however old. /clear writes no Stop
event, so its end took an unrelated earlier reason. Each caller now names its own: the chat's Stop
`user-stop`, whose event its own step wrote, and /clear `user-close`, the user replacing this chat.

* fix(native-chat): a host stop judges whether it ends work after the provider's rows land

A close, eviction or host stop decided whether it ended a running turn from the journal as it
stood, while the provider's own rows (the turn its echo opened) could still be in the session's
event sink. A close landing in that gap wrote no Stop event, so the turn it cut read as news. It
now reads after the sink drains, as a person's Stop does, through the same check; a drain that
fails or takes over a second reads working.

* fix(native-chat): a Claude Stop naming a turn that just ended still marks the follow-up it cuts

A phone names the turn it last saw. When that turn had ended and a follow-up was still unechoed,
Claude's Stop interrupted the follow-up and ended the child, but the Stop's event named the ended
turn, so the follow-up's turn the child's end cut read "Failed" under "Cancellation requested.".
A Stop that ends the provider's session ends whatever is in flight, so its event now names the
live turn or none, and a Stop that names none binds the turn opened next. Codex keeps naming only
the turn the Stop names.

The Claude Stop turn-end tests move to their own file, since the session-ending Stop suite is at
its line budget.

* fix(native-chat): the idle sweep reads working by the same rule as a stop's event

The sweep judged a chat resting while a send whose reply was lost was still unanswered, but the
stop's event writer counts that send as work. So the sweep evicted it and wrote an evict event,
which ends a person's Stop pause and let the cards behind it drain on their own. The sweep's owed
work now reads the main agent working the way every session list and the event writer do.

* test(native-chat): an aborted eviction's injected drain failure lands on the eviction's own drain

A host stop now drains the session's sink once to judge whether it ends work, so the tests that
fail the eviction's drain-published step skip that first drain.

* fix(native-chat): the idle sweep's rest writes no Stop event; it evicts a send that never echoes

The previous commit made the sweep count an unanswered send as owed work, which pins a chat whose
admitted send Codex never echoes forever, and the sweep exists to retire exactly that. That rule
returns. The sweep stops only an agent it judged resting, so its eviction now writes no Stop
event, whatever send it retires: a person's Stop pause holds through it.

* fix(native-chat): stopping a start that carries no send writes no Stop event

A host stop, eviction or close of a starting child wrote a Stop event whatever the start carried.
A start with a send already reads working, so the clause only mattered for a start with none,
which ends no turn and no send: its event only lifted a person's Stop pause and bumped the idle
clock, which is why the idle sweep had been changed to close the conversation in the same pass.
The clause goes and the sweep is #24072's again. The child's end still reads host-stop, as before.

* test(native-chat): a Stop's pause across a restart is tested with a restart that writes no event

The rig's restart closes the chat with an eviction, which now writes a Stop event when work runs
and so ends a person's Stop pause. "A Stop never hides a restart's pause" then passed with no Stop
pause left to hide anything. Those tests, and the pause-lift test whose dropped assertion returns,
restart as a process that dies with no close, which like a quit writes no Stop event, and assert
that both the Stop's and the restart's pauses are in force first.

* fix(native-chat): a host stop of a turn a person's Stop is still ending keeps that Stop's reason

An eviction or host stop that landed while a person's Stop or close was already ending the same
turn wrote a newer Stop event, and the turn's end reads only the latest, so the person's Stop of
that turn read as news. A host reason now writes nothing while a person's Stop still decides what
runs: the live turn it names or bound, or, with none, the turn a send opens next. The person's
own close still writes. The E2 tests now open and end the stopped send's own turn, as Codex does,
so the mail turn after it is not the turnless Stop's.

* fix(native-chat): an older Claude's error on a later turn keeps its error text after a Stop

The translator left an error result that names no reason to the journal's Stop rule whenever a
person's Stop named the turn or none, but the rule binds a Stop naming no turn only to the turn
opened next. So a real error on a later turn read "Failed" with its error text dropped. The
translator now asks the journal's rule itself (`personStopDecidesTurn`, the one core
`turnEndAfterStop` and a host stop's in-force check share), so the two cannot disagree.

* fix(native-chat): a Stop of a start that never landed binds no later turn, whatever sent it

A person's Stop pressed while the agent starts names no turn, and the send it stopped is
cancelled before it opens one. The Stop then bound the next turn anything opened (orchestration
mail, a restart continuation, the queue's drain, all of which send as the host), so a host
eviction of that turn wrote nothing and its crash or close read as the person's cancellation. A
Stop that named no turn now binds only a turn no send journaled after it opened: any send since,
of any origin and not refused, opens its own. The E2 test's mail send is accepted as Codex
accepts it, instead of opening the stopped send's own turn first.

* test(native-chat): a rewind's restated turnless Stop binds no turn opened after the rewind

A Codex rewind restates a person's Stop still in force after the turns it keeps, at a new
sequence, so by sequence alone it would bind the next turn opened after the rewind. A send
journaled after the restated row voids that binding (the previous commit), which this pins.

* fix(native-chat): a relaunch settles a person's stopped turn with no "stopped while in progress" row

After a restart, a turn a person's Stop ended reads "Interrupted after N" with the muted mark, but
the relaunch still added the error row saying the provider stopped mid-response, which a live Stop
never writes. The settle now skips that row when every turn it interrupts is the person's Stop's
by the journal's one rule; a crash nobody stopped keeps it.

* test(native-chat): the unexpected-exit settle's journal fake answers whether a person's Stop decides a turn

* fix(native-chat): a host stop whose sink drain fails reads the journal as it stands

A host stop drains the session's sink before judging whether it ends work, and a failed or slow
drain read as working. So an eviction of an agent at rest wrote a Stop event that ended nothing,
which lifts a person's Stop pause, and a close wrote a person's event naming no turn. The drain is
now best effort: the stop goes ahead either way and only its record is at stake, so a failed or
slow drain leaves the journal's read as it stands. A person's Stop keeps its own rule.

* fix(native-chat): a Stop that named no turn applies only to a turn a send it stopped opened

A person's Stop pressed before any turn showed names no turn. It bound the first turn opened
after it, then (5ead1f6bccd) any turn opened by no later send, so a turn the host started for
a card the Stop held, or for orchestration mail, read as the person's cancellation, and a host
eviction of it wrote no Stop event when its send had been abandoned by the close first.

The rule is now the concept itself: a Stop naming no turn applies to a turn opened by a send it
stopped, one already handed to the agent at the Stop's position. Nothing new is stored. The turn's
row names the send that opened it (Codex: the submission's key; Claude: the echo, which the journal
aliases to the submission), and a handed-over send's item sits at its handover, so the target set
is derived from the journal. A card the Stop held is handed over after it, so it is no target; a
Stop of a start whose send never opens a turn binds nothing; a rewind keeps no submissions, so a
restated Stop binds no turn opened after it. With no turn running, a host stop defers to the
person's Stop only while every unanswered send is one it stopped. Claude's translator, which asks
before its echo row lands, passes the send its echo acknowledged.

* fix(native-chat): a host stop whose sink drain runs long reads the agent working; a failed one reads the journal

A drain past its bound may still hold the turn's row, while the echo's acceptance has already
landed, so the journal as it stands read nothing running: a person's close of that turn wrote no
Stop event and the turn read as news. The two drain outcomes now differ: one that failed has
nothing more to deliver, so the journal's read holds (as before); one still running reads working.

* test(native-chat): a host stop with no turn running defers only while every unanswered send is the Stop's

The branch had no test. An eviction with only the stopped send unanswered writes nothing; one
with a send made after the Stop still unanswered writes its event.

* fix(native-chat): a slow sink drain reads working only while an accepted send's turn row is due

The previous commit read every drain past its bound as working, so a host eviction or stop of an
agent at rest during a sink backlog wrote a Stop event that ended nothing and lifted a person's
Stop pause. A slow drain now reads working only when the latest send the agent accepted has opened
no turn the journal holds, the race it was for; otherwise the journal's read holds.

* test(native-chat): the host-stop control keeps the stopped send unanswered beside the later one

With both unanswered, the host writes only because not every unanswered send is the Stop's; a rule
that deferred when any one was would pass the old control.

* fix(native-chat): a steer is no send owed a turn when a slow drain judges a host stop

A slow drain reads working when the latest accepted send has opened no turn yet. A Codex steer or
a Claude fold is accepted into the running turn and never opens one, so a chat at rest whose last
send was a steer still read working, and an eviction lifted a person's Stop pause. Sends delivered
into a running turn, whose item carries that turn's scope, are skipped.

* feat(native-chat): a chat reads Stopping from the person's Stop until the work it stopped ends

The host derives it on each journal publish from the Stop's event, the live turn and the Stop's
own answer, and publishes it as an optional field on the session status and the main agent's row.
Clients present it: the chat's tail line and Stop control, the sidebar row, worktree ps and the
phone's row. The chat and the phone also read their own Stop press until its request answers.

* test(native-chat): pin Stopping on the phone and across mixed versions

* test: give touched fake journals and mocks their SAFETY notes

* test(native-chat): a turn waiting on the person reads attention, never Stopping

* test(native-chat): the sidebar row follows Stopping when it is the only field that moved

* test(mobile): the phone reads Stopping from its own Stop until the request answers

* test(mobile): type the held Stop request instead of casting it

* chore: keep the base lockfile (a local pnpm run rewrote it)

* fix(native-chat): narrow the Stop note's optional failure; type the phone test's reply

* test(native-chat): type the Stop test envelope's fields narrowly

* fix(native-chat): a Stop the agent declined, or whose child end failed, says so while the turn runs on

A Stop naming the turn that still runs, refused by the agent, now writes the
Stop's refused fact instead of 'already finished'. A session-ending Stop whose
child end fails while the work runs on revises its note to unconfirmed.

* fix(native-chat): Stopping holds while any press of the Stop took

A repeat press refused after an earlier press took no longer clears Stopping.
Exit early when the Stop named a turn that is not the live one.

* fix(native-chat): keep Stop enabled while the host says Stopping

Only this client's own Stop request in flight disables Stop and Esc. A repeat
Stop is how a stop the provider took but never answered escalates.

* fix(sidebar): every agent row says Stopping in place of its tool line

The dashboard row, which the sidebar's non-compact mode also draws, read the
last tool line while a person's Stop ended the turn. It now shares the compact
row's rule.

* fix(mobile): the worktree list sees Stopping change on its own

A snapshot whose only change was the host dropping Stopping compared equal and
was thrown away, leaving the row on Stopping.

* refactor(native-chat): fold the status feed in src/shared for both clients

The snapshot merge and the contact-loss strip move out of the renderer feed so
the phone folds the same stream the same way.

* feat(mobile): let phones read the structured session status stream

agentSession.subscribeStatus joins the mobile allowlist. The agent-session
methods move to their own file, which the at-cap allowlist spreads in, and the
allowlist test reads the Set instead of parsing the source.

* feat(mobile): the phone chat reads Stopping from the host, like the desktop

One status stream per client, opened on a host that advertises the status feed;
a refusal to phones reads as no feed. The chat reads Stopping from the host or
its own press, and holds Stop only while its own request is in flight.

* test: give the new fakes checked types or a SAFETY reason

* revert(native-chat): drop the refused-named-turn rewrite of a Stop's note

Codex can send its refusal before the turn's end frames, so reading the turn as
still live after a flush races; the Codex Stop that ends nothing is handled by
ending the process instead. The base's 'already finished' note and its test
expectation return. The Claude wind-down failure revise stays.

* fix(mobile): release the status stream when the host ends it; refusals last one connection

The feed now drops the handle of a stream the host ended or refused, so the
logical client never replays it on a later session. A refusal to phones holds
for one connection, so a host updated while the phone stays paired is asked
again.

* perf(native-chat): read the live turn's opener from its record when deriving Stopping

After a Stop that named no turn, every later commit walked and copied the whole
journal to find the live turn's record. The derivation now reads that record
off the rendered snapshot's tail and decides with the same rule.

* refactor(mobile): move the method-unavailable check into transport

The status feed imported it from the Files tab's fallback. No behaviour change.

* test(native-chat): a send after a Stop reads Working before its turn opens

Pins the derivation's running-only read of the newest turn: the stopped turn,
already ended, must not keep the next send on Stopping.

* fix(sidebar): the compact row leads with Stopping so a narrow sidebar keeps it whole

At the default width the row read 'Codex Chat - Stoppin…': the model and time
keep their room and the line truncates from the end. Stopping now leads the line
the way monitoring already does, so the chat name is what gets cut. Also pins
that the turn bar keeps its running clock while the tail line says Stopping.

* test(native-chat): the retry of a close whose exit was unproven writes no second Stop event

The idle sweep finishes a stop left owed with that stop's own cause. It is the same stop, so its
event stands alone and the child's end keeps the cause, for a person's close and an eviction.

* fix(native-chat): read and write a Stop's answer by the turn its event records

Stop notes are now one row per turn, keyed by the turn the Stop's event
records. Performing a Stop and deriving Stopping share that key. A refused or
unconfirmed answer never overwrites one that took at the same key; only a
session-ending Stop's failed wind-down downgrades it, and that step now revises
the note the Stop actually wrote, carried on the wind-down. Stopping reads the
turn's note whenever it was first written, plus newer notes no other turn owns.
Test fixtures gain the host logger and the phone's quietRepeatedStop.

* refactor(native-chat): read a Stop's target once for its event and its note

The chat's Stop now reads what it is aimed at (the named turn and whether the
Stop ends the provider session) once, and both its event and its note's key
derive their turn from that one value through the same rule. Adds the host test
for a Stop naming an ended turn on a provider whose Stop ends the session.

* fix(native-chat): the host never steers a message into a turn a Stop is ending

A queued card's Send-now, or a send made while a person's Stop ends the turn,
went to the agent as a steer into that turn. The delivery loop now holds any
waiting message while the host's own Stopping reading holds, and sends it as
its own turn once the turn ends. The Stopping reader also stops at the Stop's
position and looks the turn's note up by key, instead of walking the whole
journal.

* feat(native-chat): while Stopping, the composer says a message runs after the stop

Desktop and phone: the composer placeholder reads "Queue a message to run
after the stop" while the chat reads Stopping, and a queued card's Steer (and
the desktop's steer shortcut) is held. New key translated in all 6 catalogs.

* refactor(native-chat): the chat pane's Stop controls live in their own module

The pane went over its line limit once merged with main. Its Stopping reading,
the press that holds Stop, and the steer and placeholder it hands the composer
move to native-chat-structured-stop-controls.ts.

* fix(native-chat): hold a send at its handover, reading the feed's own Stopping

The hold was checked when the delivery step started, but the handover runs in a
later step after waiting on the agent's start, so a Stop landing in between let
a new send steer into the stopping turn. The check now runs at the handover.
It reads the status feed's projection for the commit instead of rendering the
journal again, so holding a send adds no journal read of its own.

* refactor(native-chat): one display status decides Stopping on every surface

agentStopDisplayStatus combines whether the agent works, the host's flag and
this client's own press. The chat pane, sidebar and dashboard rows, and the
phone's chat all read it, instead of each combining the flags.

* fix(native-chat): Stopping holds until the stopped turn ends, whatever the Stop's answer

A Stop the agent declined, or whose end went unconfirmed, used to drop the chat
back to Working. It now stays on Stopping until the turn ends, and Stop stays
enabled so a repeat press escalates. The Stop's answer is no longer read for
Stopping, so its note goes back to the key the base gives it (the restore of
queued-stop.ts and the removed key test landed in the previous commit). The
note still keeps a press that took over a later refusal, and a failed process
end still says the Stop went unconfirmed.

* fix(native-chat): a Stop binds only the turn it actually stopped

A Stop pressed before any turn showed used to claim, at end-write time,
whatever turn the stopped send later opened, even when the Stop stopped
nothing. A turn that then died on its own read as "Interrupted" (your
cancellation) instead of "Failed".

Now a person's Stop that named no turn binds, in memory only, every turn
that ends while the Stop settles, and afterwards only the turn its
interrupt took. The settle ends a still-running stopped turn once. A
relaunch finds nothing in memory, so an unsettled turnless Stop binds no
turn. A Codex Stop whose answered turn does not open within its wait, or
whose send's answer was lost, now answers refused, so the host ends the
child and the turn can never run.

* fix(native-chat): keep the person's queue pause and close binding after a Stop settles

A host stop or eviction with no turn running now defers to a person's
Stop while its queue pause still holds with nothing sent since, read from
rows, so a held card is not handed off on reopen after a Stop that did
nothing or whose kill failed.

A person's close that named no turn opens a settle around its child's
end, so a turn that end cuts reads as theirs.

A press opens its settle only when the latest Stop event is its own or
the one in force it repeats: a late Stop, a card's interrupt or a lost
event row reopens no earlier Stop.

A Codex Stop that cannot reach a turn still able to open says the Stop is
unconfirmed rather than that no turn ran, and a second Stop still reaches
a turn an earlier wait left unopened.

Also drops the unused openedBy plumbing and the unreachable "a written
cancellation stays one" rule, and pins a relaunch after a named Stop.

* fix(native-chat): keep a failed Stop's turn display-only, and settle edges off the commit path

A Stop that failed marks the turn it could not stop for "Stopping…" only
(JournalStopSettle.failedOn): no turn-end rule reads it, so that turn's
own end with no verdict reads as a failure, not the person's.

A settle edge writes no row, so it no longer goes through the journal's
commit listener, which also delivers history, counts as activity for the
idle sweep and schedules the queue drain. A narrow settle-edge hook
republishes the status row and wakes the steer hold's handover, and
nothing else.

* fix(native-chat): a Codex Stop agrees on both presses when a turn is still owed, and pin the close's settle

A Codex Stop that waited for a turn Codex answered a send into now answers
"may still open" whenever that turn neither opened nor ended and its send
is still owed, however the wait ended (it ran out, or the thread went
idle). Before, a first press after an idle thread said no turn was
running and kept Codex, while an identical second press ended it.

Adds a test that a person's close the conversation outlives (as /clear
does) closes its settle, so a later turn that ends on its own reads as a
failure.

* fix(native-chat): a Stop that failed before its turn showed still reads Stopping through that turn

A Stop that failed with no turn open marked nothing, so the chat dropped
to Working and the turn that then opened never read "Stopping…". The
display-only mark now also covers that case: the first turn that opens
after the Stop failed, provided no message was handed to the agent in
between. No turn-end rule reads the mark, so that turn's own end with no
verdict still reads as a failure.

* test(native-chat): a Stop whose event row failed binds no turn to an earlier Stop

With one ordered journal writer the Stop's event is in the fold when its
write returns, so the press reads whether it owns the latest Stop from the
fold instead of awaiting the write. Pins the case the read must refuse.

* test(native-chat): name the settle, not a stream drain, in the Stop's own-end test

* test(native-chat): a Codex Stop answered before Codex ends the turn reads interrupted throughout

Codex answers an interrupt it took before it sends turn/completed (interrupted):
on TurnAborted the app-server answers pending interrupts, then ends the turn, on
one channel. The test fake did the reverse. It now answers first and ends the
turn on a later read, and the tests that read the turn's end right after a Stop
wait for it.

New end-to-end test through the shipped host, journal and Codex adapter: with
the real order, every end row of the stopped turn reads interrupted by the Stop
(named, unnamed, and a Stop pressed while turn/start was in flight). Breaking the
settle window turns the in-flight case red: the Stop's own end row then has no
verdict, which reads as failed until Codex's end lands.

* test(native-chat): Stopping ends with a Codex turn whose interrupt is answered before its end

With Codex's real order (the interrupt's answer, then turn/completed interrupted),
the status shows Stopping while the Stop settles, drops it once the turn ends, and
never carries a verdict other than the person's cancellation.

* fix(native-chat): a Codex Stop interrupts a turn Codex answered but has not opened at once

A Stop that named no turn, made after Codex answered a send but before the turn
opened, used to wait up to 5 s for the turn to open before interrupting, and
ended the Codex process when it didn't. The stated reason, that Codex refuses an
interrupt until it opens the turn, holds only part of the time: with no turn
active, Codex takes an interrupt once its thread runs (turn_interrupt_inner),
and refuses it with -32600 "no active turn to interrupt" before that or once
the turn has ended.

The Stop now sends the interrupt at once. Only on that refusal, while the turn
has neither opened nor ended, does it wait for the turn to open (bounded at
5 s) and send it once more. A turn that ended meanwhile was nothing to stop. One
that never opens, or that an earlier wait already gave up on, fails the Stop,
and the host ends the child as before. Sends still wait for the turn to open
before steering into it.

The test fake models Codex taking an interrupt once the thread runs (run()).

* fix(mobile): name how the phone's status stream is released in the subscription inventory

Main made each inventory entry state its release; the status feed's stream is
released from its subscribe params, as the session event stream is.

* fix(native-chat): every Codex Stop waits for an answered turn to start, as the first did

A Stop whose interrupt Codex refused as finding no active turn skipped the wait
when an earlier wait, a Stop's or a send's, had already given up on that turn.
Every press now waits its own bound and retries once if the turn starts, so a
turn that opens during a later press is still stopped. Both presses still reach
the same verdict when it never starts.

* fix(codex): never steer a turn whose interrupt Codex answered

Codex answers an interrupt as the turn aborts, before it sends that turn's
turn/completed. In that gap the adapter still counted the turn as running, so a
message handed over right after a Stop settled (the Stop's own end row already
reads the turn ended) went out as turn/steer, which Codex refused with -32600
"no active turn to steer", and only then as turn/start. The adapter now marks a
turn whose interrupt Codex answered as aborted until its turn/completed, never
steers into it, and starts the message's own turn directly. Steering a turn
that is genuinely running is unchanged.

* fix(native-chat): a message sent while Stopping is queued as a card, whatever the setting

While the chat reads Stopping (the host's flag or this client's own Stop in
flight) there is no turn left to steer into, so the desktop asks the host to
queue the send even with the queueing setting off, and it is never drawn as a
bubble inside the turn being stopped. The phone already queued every send on a
capable host; a test now pins that it does so while Stopping.

* fix(native-chat): a message queued while Stopping is a card at once, not after the stop

A person's Stop holds the session's lane until Codex answers its interrupt, and
a send was admitted only behind it. By then the turn read ended, so a send that
asked to be queued went out plain: no card for the whole of Stopping, then a
bubble and a new turn.

While the host reads that a person's Stop is ending the work, a text send that
asks to be queued is admitted without waiting for the lane: the same ledger and
lease admission, and a plan that only writes the card through the journal's
ordered writer. The card runs when the stop lands; the Stop's pause holds only
cards queued before it. Anything else, including a Stop that settled by the
time the send runs, takes the lane as before.

The Codex test fake now drops the active turn when it takes an interrupt, as
Codex does before it answers, so a turn/start after the answer opens a new turn.

* fix(native-chat): a Codex Stop that ends the child before any turn opened withdraws its send

A Stop on a Codex turn that was answered but never opened ends the Codex
process. That end settled the send as in doubt (unknown, recovered), and the
client's outbox holds every later send behind a send in doubt until the person
presses Retry, which re-sends the very message they stopped. The chat looked
stuck.

Codex records a prompt only once its turn has started, so a send whose turn
never opened never ran. When the Stop's refusal says so (turnMayOpen), the child
end now settles the unanswered sends as withdrawn, the verdict Codex's own
interrupted-turn end already gives an unechoed send. The flag rides on the owed
wind-down, so a retry after a failed child end withdraws them too. Claude's
child end still leaves its unanswered send in doubt.

* fix(native-chat): derive the withdrawal of a Codex send whose turn never opened

Replaces the flag the Stop carried to the child's end, and its copy on the owed
wind-down, with a reading of the journal at the settlement that lands. A Codex
child's unanswered send is withdrawn when a person's Stop is in force since it
was sent and no turn row ran, or was written, after it; any other end (a turn
that opened, a host's close, a crash, Claude) still leaves it in doubt. A
retried wind-down reads the same rows, so it withdraws the same sends.

* fix(native-chat): a card queued while Stopping runs past the cards the Stop holds

A card queued before a person's Stop waits under its pause until Resume. One
queued after it, as a message sent while Stopping now is, was stuck behind them
too, since the queue never reorders. Such a card was asked for after the Stop,
so it runs when the stop lands, past the cards held only by that Stop's pause;
a returned card and the restart and /clear pauses still hold everything behind
them.

Also: the host's own Stopping reading is gated on working, as the published
flag is, so a failed Stop's mark never reads Stopping on an idle session; a send
that falls back to the lane re-reads the conversation's journal there; and the
end-to-end test asserts the queue's pause rather than a per-card field.

* fix(native-chat): a paused queue labels only the cards it holds

Since a card queued after a person's Stop runs past the cards the Stop holds,
labelling every card "paused" while the queue's pause is published misreads that
card. The host now marks each card its pause holds (heldByPause, a new optional
field), and the desktop and phone label only those. An older host marks none,
so a client keeps today's labels; an older client ignores the field.

Adds a test of the desktop's own send through the real outbox: while the chat
reads Stopping, the request asks the host to queue it and no bubble is drawn,
on a host that advertises the queue.

* revert(native-chat): defer the per-card queue pause label to the queue's rollout

The heldByPause field and its labels are visible only where the host
advertises the queued-messages capability, which shipped hosts do not yet do.
Deferred to that rollout; the real-outbox send test stays.

* fix(native-chat): while Stopping, say and show what a send does where the queue is dark

Shipped hosts do not advertise the queued-messages capability, so a message
sent while Stopping goes out plain: the host holds it until the stopped turn
ends and then runs it as its own turn. The composer still said "Queue a message
to run after the stop", and the message was drawn inside the turn being
stopped.

Now the placeholder reads "Send a message to run after the stop" where the host
does not queue sends, and "Queue a message…" only where it does (desktop and
phone, all six catalogs). A send this client made that the host has not
recorded yet is drawn after the Stopping line while the chat reads Stopping, as
a message held behind a running command already is; once the host hands it
over it opens its own turn. Client presentation only.

* fix(native-chat): keep a send in doubt when a turn was open for it

The derived withdrawal read a turn as open for a send only if it still ran or
was written after the send. A send steered into a running Codex turn whose
interrupt failed met neither once the adapter's end settled that turn ahead of
the host's settle, so it read withdrawn, though Codex drains a steer into the
running turn and may hold it. A turn that ended after the send was handed over
was open for it too: such a send stays in doubt, as before.

Pins that case, and that a send made after the Stop, to a child that then dies
before its turn opens, stays in doubt.

* fix(native-chat): restore the per-card queue pause label

Kept after all: a paused queue labels only the cards it holds (heldByPause),
which is visible only where the host advertises the queued-messages capability.

* fix(native-chat): draw only a send made while Stopping after the Stopping line

Every send the host had not recorded yet was drawn after the Stopping line,
including one made just before the Stop, which the host steers into the turn;
it then jumped up into that turn once recorded. The outbox now marks a send
made while the chat reads Stopping, and only those wait after the line.

* fix(native-chat): withdraw a Codex send by whether it started its own turn, not by timing

Whether a turn was open for a send was read from end times: a turn that ended
after the send's handover counted. A send made while a Stop ended the turn is
handed over once that turn reads ended, yet Codex's own end for it can arrive
later, so such a send whose own turn never opened read in doubt again, and the
chat's queue held behind it.

The handover already records where the send went: its message joins the turn
running then (a steer) or belongs to no turn (it starts its own). Only a send
that started its own turn, with none opened since, is withdrawn; one that
joined a running turn, or has no recorded place, stays in doubt.

The Codex test fake takes an answered interrupt as Codex does, dropping the
turn before its end arrives.

* refactor(native-chat): move queue-while-stopping to its own follow-up

The queued-messages capability is off on every shipped host (#21062), so the
parts of this PR that act only when it is on move to a follow-up stacked on
this one: admitting a queued card while a Stop holds the session's lane, a card
queued after a Stop running past the cards it holds, the per-card pause mark,
and asking the host to queue a send made while Stopping. This PR keeps the
Stopping state, the host's steer hold, the rule that never steers a turn whose
interrupt Codex answered, and what a send while Stopping looks like where the
queue is off.

* fix(native-chat): leave no Stop row when the Stop took back a send that never ran

A Stop on a Codex send whose turn never opened ends the child, and the child's end
takes the send back into the composer. The Stop still wrote "Cancellation
requested." at the conversation level, so with the send gone it sat under the
previous finished turn and read as if that turn had been stopped. A Stop that found
no turn running and whose child end took back every send it found now writes no
row; a Stop of a running turn, or one that leaves a send in doubt, still does.

* feat(native-chat): keep a message a Stop took back on screen, with one stop row after it

A Stop that took back a message before the agent started it used to remove the
message from the transcript and paste its text back into the sender's composer.
Other devices just lost it, and with the message gone there was nowhere for a
stop row to sit, so it either landed under the previous finished turn or was
left out.

The message now stays where it was sent, on every client, followed by one row,
"Stopped before the agent started" (one row after several taken back together).
A message whose turn had opened stays in that turn, whose "Interrupted" header
already says it was stopped. A queued card's hand-off is still held by the card.
Nothing the host recorded refills the composer any more. Text this client's own
Stop took before the host ever had it still comes back, and only into an empty
composer.

Derived from facts the journal already holds (the rejected submission's
cancelled verdict and its user item); nothing new is stored or sent.

* fix(native-chat): one stop row per stopped send, drawn where the Stop took it, and nothing lost

- A message this window's Stop took before the host had it, which the composer
  cannot take (it holds text or images, or no composer shows the chat), now stays
  in the outbox as not sent, on its Retry, instead of vanishing.
- A Codex send whose turn opened but was never echoed belongs to that turn: its
  interrupted end is the stop, so no second row is drawn. A send taken back after
  a later turn started still gets its own row.
- A steer the Stop took back stays in the turn it joined, with no row of its own.
- A queued send taken back before its hand-over is drawn after the turn it waited
  behind, not inside it.
- The conversation outline the host serves still leaves out sends a Stop took
  back, and the rail gives them no tick, so what the host publishes is unchanged.
- The row is drawn as the Stop's own status rows are, and never folds behind a
  settled turn on a host that states no turn scopes.

* fix(native-chat): draw a stopped follow-up after the turn that opened while it waited

A follow-up sent just before the agent opened its turn, then stopped, drew its
"Stopped before the agent started" row above that turn's own "Cancellation
requested." whenever the turn was expanded. A send a Stop took back is now drawn
after the rest of every turn it waited on: the one it was accepted behind, and
any that opened after it and before the Stop took it back.

Also corrects the stoppedBeforeStart doc to what sets it.

* fix(native-chat): place a stopped send by journal order, not by turn start time

The turn a stopped send waited on was picked by comparing the turn's start time
with when the Stop took the send back. A Codex resume rewrites every finished
turn's start time to Codex's whole seconds, so after a restart (or a child
respawn) a turn opened for a later send could read as started first, and the
stopped send dropped below that whole later exchange. A turn is now waited on
when something sent before the stopped send opened it, read from the journal's
own order only. Covered end to end through a restart whose resume reports
whole-second start times.

* test(native-chat): pin a stopped send held behind the first send's answer

A second send made while Codex still held the first send's turn/start answer,
then a Stop: the first turn opens after the second was accepted and streams after
the Stop. The stopped second send and its row are drawn after that turn's output,
never between the turn's header and its output. Fails on the two earlier
placement rules. The restart case moves into the same file.

* docs(native-chat): say why the pre-echo anchor still compares times

* docs(native-chat): mark the pre-echo anchor's time compare temporary (STA-9337)

* docs(native-chat): say the placement rule reads journal position, not send time

* fix(native-chat): keep sends a Stop took back in the order they were sent

Two sends queued during /compact, the first handed over and the second not,
then a Stop that took both back: the handed-over one sat at its handover row and
the other at its acceptance, so the second drew above the first. Among sends a
Stop took back, a later-sent one is now drawn no earlier than just after an
earlier one. Sent order is submittedAt, the host's accept time and the order
every client already keeps submissions in, because a client never sees a
handed-over send's acceptance position (STA-9337).

* fix(native-chat): draw a stopped send below everything sent before it

A send a Stop took back that was never handed over could still draw above an
earlier send's whole exchange when that earlier send was not itself taken back:
three queued during /compact, the first ran and finished, the second was left in
doubt, and the Stop took back only the third. A stopped send is now drawn no
earlier than the latest loaded row of anything sent before it, and the turns it
waited on are read from that point, so the earlier exchange stays above it.

* fix(native-chat): count a turn opened by the floor row as one the stopped send waited on

When the latest row sent before a stopped send was itself a turn's opener, that
turn compared equal to the floor and was not counted, so the stopped send landed
inside the earlier send's exchange: two queued during /compact, the first handed
over and streaming, then a Stop took back the second. A turn whose opener sits at
or before that point now counts, and the send draws after the whole exchange.

* feat(native-chat): publish each submission's journal positions

A client never learned where in the journal a send was accepted or taken back,
so drawing a stopped send had to guess from its own row and from clocks, and the
guesses misfired after restarts. Each projected submission now carries
`submittedSequence` (its submission row) and `resolvedSequence` (the dispatch row
that resolved it; absent while pending): two optional fields, computed on every
fold from rows already stored, never stored themselves. Older clients ignore
them. The failure-fact schema moves to its own module to keep the journal schema
file within its size limit.

* fix(native-chat): place a stopped send by the journal row that took it back

Hosts now publish where each submission and its resolving row sit in the journal (cherry-picked from #25073). The projection places a send withdrawn before it started at that row, keeps stopped sends in their published submission order, and falls back to the send's own row on hosts that publish neither.

* test(native-chat): pin a submission's resolved position on the provider-echo accept path

Also say which rows can resolve a submission, and that the submission schema, not the shared type, omits acceptedSequence.

(cherry picked from commit 58a1ade5048669b1aadbac65799a6913152a9981)

* fix(native-chat): keep the previous placement rules for a host that publishes no positions

On a host from before the published journal positions, a stopped send is again drawn after the latest row of anything sent before it, as before the switch, so it no longer draws above the earlier exchange. Temporary until a host version floor. Also pins the published row against tied accept times.

* perf(native-chat): place stopped sends in one pass, and skip it in chats with none

The message projection runs on every streaming commit. It now builds turn anchors, the item lookup and the older-host floor only when the chat has a send a Stop took back, and places each such send with a binary search over the turns' furthest rows instead of rescanning every item per send. Draws are unchanged.

* fix(native-chat): count a send whose answer was lost when a Stop takes it back

The no-row rule counted only pending sends, but the child's end also takes back a send this process left in doubt when Codex's turn/start answer was lost. That case still wrote "Cancellation requested." under the previous turn. Both now read one predicate, so they cannot drift apart.

* test(native-chat): pin which sends a Stop's child end can take back

A send an earlier process left in doubt is never withdrawn and never holds the row back, and a queued card's send is never counted.

* fix(native-chat): read the host's Stopping beside main's startup phase

Main now reads only the startup phase from the status feed and no longer publishes which
child is starting. The chat reads the host's Stopping from its own hook beside it, and the
Stopping bridge test mocks the execution-host lookup main's owner resolution now calls.

* test(native-chat): phone draws the same from merged frames as from a fresh snapshot

A long chat whose last send never opened and was taken back at the child's
exit, right after a send made while a Stop was ending the turn before it.
From every subscribe point, at every later frame and with frames that carry
one to three rows, the phone's list built from merged frames must equal the
list built from a fresh snapshot of the same journal.

* test(native-chat): widen the merged-vs-snapshot guard to content, long chats and the phone hooks

The guard compared row ids and turn bars only, never left the phone's first
window, put each row's writer fence on every batch, and stopped at the fold.
It now:
- compares each row's content, so a phone that kept an earlier revision of an
  answer or a status fails it;
- adds a chat longer than the phone first loads, compared from the fresh
  page's first user row on (a turn whose user row the page cut off is keyed
  differently there);
- sends batches at the subscriber's fence and a fresh snapshot when the fence
  moves, as the host's attach does;
- writes the send made while stopping while the turn still runs, adds the
  provider's echo of each send, and a status row the provider drops;
- adds a hooks test: a phone that sent the never-opened message itself, holding
  its echo and reading the host's Stopping from the status feed, shows the same
  list after every frame as a phone that opened the chat fresh then.

* test(native-chat): pin the stop row to every frame from the one that took the send back

Both guards compared a merged phone with a fresh one, so a list bug they
shared passed, including one that held the stop row back until the next send.
Both now check, at every frame from the take-back on, that the list itself
shows the stop row: the data test through the list's own turn disclosure, the
hooks test on the live and the fresh phone.

Also:
- the send made while stopping is written after the stopped turn's end, as
  the QA journal shows, and while the turn still runs, as a second case;
- the long chat revises and drops a status near its end, inside the window;
- each phone reduces its own copy of every frame;
- Stopping is checked on the never-opened send's own Stop;
- the headers say what neither guard covers;
- the mobile production typecheck leaves *.test-fixture.ts to the tests'
  program, as it does tests, since these fixtures import desktop host code.

* test(native-chat): check the stop row in the chat view's FlatList, through the real overlay

The hooks guard rebuilt the overlay and chat view by hand, so a memo in the
real view that held its list back until the next send passed it. The guard
now renders the real overlay and chat view from the phone's own hooks, and
checks the stop row in the FlatList's data at every frame from the one that
took the send back. It also subscribes once before the history's last
dropped status, so removals run through the real hooks too.

* test(native-chat): compare the live and fresh phone on the chat view's own FlatList

The hooks guard compared a hand-built copy of the overlay and view, so a memo
in the real ones keyed on list lengths kept stale rows past it. It now
compares, after every frame, what the real chat view hands its FlatList:
each row as its renderItem draws it, with its bar, and the footer. The
hand-built copy is gone. It also checks that the FlatList's keys never
collide and that a changed list never arrives in the same array, and the
controller stub's SAFETY note now states what the stub really provides.

* test(native-chat): read the outbox reconcile from where main moved it

* test(native-chat): pass the projection's options and mock the phone row's new imports after main's rejected-in-place rows

* refactor(native-chat): place a taken-back send by where the host now puts its row

#24710 moves a rejected send's row, a Stop's take-back included, to the row
that rejected it, in no turn. Draw it at that row, past the end of every turn
opened before it, and keep the send-order rule. A send whose turn opened before
the provider echoed it is claimed by that turn's record when it was sent before
the record and taken back after it, by submittedSequence, and is drawn as the
turn's opener. The steer branch goes: the host no longer says which turn a
taken-back steer joined, so it is drawn after that turn with its own row.
The older-host fallback (floor, clock compare, submittedAt order) is now gated
on submittedSequence alone and marked Temporary. resolvedSequence is gone, as
in #25073.

* test(native-chat): a turn recorded before a send was made is not the turn it opened

* test(native-chat): a message a Stop withdrew is drawn with its stop row, not hidden

#24710's tests pinned a withdrawn send as hidden, the rule this PR replaces.
Each keeps what it is about: a withdrawn copy does not hide a failed one, no
delivery notice is raised, and a message the host failed to deliver stays
hidden on the phone.

* fix(native-chat): a retried message no longer waits behind a later Stop

Retry dropped the Stop it had outlived but kept the mark that it was sent while
a Stop was ending a turn, so a retried message waited behind whatever later,
unrelated turn a Stop was ending. Retry is a new send: drop that mark too.

* feat(native-chat): publish the turn a withdrawn Codex send was answered into

Same change as #25073 at 93749070e48b, so this stack builds on it.

* feat(native-chat): say how a withdrawn Codex send joined the turn it names

Same change as #25073 at ab2826ee1854, so this stack builds on it.

* fix(native-chat): open a turn for a stopped send only when the host says it started it

A send a Stop took back after its turn opened but before Codex echoed it
is drawn as that turn's opener when the host names the turn and says the
send started it. A steer into that turn keeps its own row after the turn.
The guess from journal order and times is kept only for hosts that
publish neither field, and never hands a turn the provider resumed on its
own to a send. A page that starts inside such a turn draws the send
before the turn's first loaded row.

* test(native-chat): an echoed opener keeps its turn from a send the host says started it

* feat(native-chat): state on every rejection whether it names a turn

Same change as #25073 at e02f98add56b, so this stack builds on it.

* fix(native-chat): place a stopped send from older history by journal order

A rejection written before the host named turns carries no answered turn,
though a newer host still publishes where it was sent and has moved its
row to the take-back. Such a send is matched to its turn by journal order
again, as before the host named turns; a rejection that states no turn
opens none.

* docs(native-chat): say an unreadable answered turn reads as none

Same change as #25073 at 4ab6cc431c01.

* refactor(native-chat): order stopped sends without non-null assertions

One helper sorts by the published send position when every entry has it,
else by accept time, and both stopped-send sorts use it. The rule kept for
rejections written before the host named turns is labelled as kept for
good: it draws those rows exactly as before.

* docs(native-chat): say which half of the older-history turn rule is kept for good

* fix(native-chat): word a send after a Stop by whether this send will queue

The 'queue a message to run after the stop' placeholder read the host's
queue capability alone. A send queues only when the host queues and this
send asks it to: the queue setting is on and no pending prompt blocks the
queue. Desktop and phone now word the placeholder from that same decision
their send uses.

* test(native-chat): one test per case for the words of a send after a Stop

* refactor(native-chat): the dictation hook owns the composer's dictation state

Keeps NativeChatComposer within its line limit after the Stop props and
main's /context answer both landed in it.

* fix(mobile-chat): a send a Stop took back is not handed back to the draft

A send whose answer says a Stop withdrew it is drawn in the chat with
its stop row, so handing its text back to the composer as well showed it
twice. It reads as sent and spends its id; other rejections still go
back to the draft as main has them.

* refactor(native-chat): name the dictation hook for what it owns now

* fix(mobile-chat): resend a retained replay a Stop took back, under a fresh id

A retained id is keyed by the message text, so its replay cannot be told
from a new send of the same text. When the answer is a submission a Stop
withdrew, that message provably never ran, so the phone sends it once
more under a fresh id, as it already does for a withdrawn queued card.
A first answer a Stop took back still reads as sent, as on desktop.

* test(mobile-chat): count every send a withdrawn replay makes

* fix(mobile-chat): a resend a Stop took back again is not handed back to the draft

When storage fails, a resend's answer is lost and a second Stop takes
the resend back, the fall-through after a withdrawn resend returned the
text to the draft beside its stopped row. A withdrawn submission there
now reads as sent; a withdrawn queued draft still goes back. Pins the
one-resend guard and both orders of the stopped row and a resend.

* fix(native-chat): a Stop's note says it took once a joined close proves the exit

A session-ending Stop whose child's end failed revises its note to
'unconfirmed'. Since main's #24862, the next Stop joins that close rather
than stopping again, and wrote no note, so a close that then proved the
exit left 'unconfirmed' under a turn that ended. The close now carries
the note it settles, and its proven exit revises it to 'Cancellation
requested.'. A join that fails again leaves it unconfirmed.

* test(native-chat): draw a stopped send end to end in this PR's own Codex file

The shared turn-end settlement file went past its line limit once main's
Stop tests and the answered-turn tests met. This PR's two drawing checks
move to its own end-to-end file, leaving that file as #25073 has it.

* fix(native-chat): a proven turn end says a Stop's unconfirmed note took

Replaces the note carried on the child's close. Every settlement that
ends turns interrupted on a proven exit, live or after a crash, also
revises an unconfirmed Stop note on those turns to 'Cancellation
requested.', found by the note's turn scope, in the same batch. A note a
Stop wrote before its turn showed is re-keyed onto the running turn when
it becomes unconfirmed, in one batch, so that end finds it. Known limit:
with no turn open yet, the note keeps its key and no turn's end revises
it.

* test(native-chat): a Stop's unconfirmed note says it took when the agent exits on its own

* test(native-chat): restore the named Stop, turn anchor and role checks in the moved draw tests

* test(native-chat): name the Codex handle as main's opaque handle does

* test: restore the provider handle import the main merge dropped

* fix: derive Stop note wording from interrupted turns

* test: name the raw replay case for what it covers

* refactor(native-chat): move the waiting-slot split into its own hook

* test: follow main's chat font-size rename in the stopping tests

* test: follow main's single live-line value in the Stopping tests

* test: give the android live-line fixtures the stopping field

* chore: keep the session host under its line limit after the main merge

* test: follow main's card field and live-line component in the stop-withdrawn tests

* chore: keep the composer test and the phone chat view under their line limits after the main merge

The Stop control now disables itself while Stopping, so the composer passes
the flag through and its test file stays as main has it. The phone chat
header's Stop moves to its own component.

* perf(native-chat): read a Stop note's fields before parsing its key on every snapshot

Every snapshot projects each item through the Stop-note read, and each new
snapshot rebuilds the index of Stop notes by turn. Both parsed every item's
key first; they now check the row's kind and turn scope (and, for the
projection, its unconfirmed-stop failure) before the parse. Every Stop note
is a status row, so what each finds is unchanged.

* fix(native-chat): keep the Spanish 'Stopped before the agent started' in the one notices block; the phone parity test reads Stopping from the live line

Subject: [PATCH 162/167] Name native Claude and Codex chats after their first
 message (#25724)

* feat: generate chat names through configured text agents

* Project structured chat names across stored tabs and session rows

* Name native chats from their first live message

* Restore the journal test provider handle import

* Fix first-message naming and live Vault title updates

* Preserve Unicode characters in bounded chat naming prompts

* Read chat naming settings only when a turn needs them

* fix(chat): store only generated conversation names

* fix(chat): keep ordinary labels across unnamed chat surfaces

* fix(chat): preserve naming after fast first turns

* Preserve native chat names across command-first sends and Vault lifecycle

* Route native chat SQLite contracts through the existing Node test pool

* feat(settings): add chat naming controls to Chat page

* Preserve chat naming drafts and configure Custom commands through host settings

* Scope synthetic command output to its journal thread in naming test

* Keep naming test fixtures within their typed project boundaries

* Resolve the real Vault hook directly in its integration test

* Publish chat naming save refs after render commits

* fix: keep Japanese chat naming copy stable during repair

* Update test contracts for the naming integration

* Keep journal fixture reads on the host clock

* Give Chat names a separate settings section

 ### Sync log
 
+**1.4.214 → 1.4.214** (`2b0ce17514..51062e653e`, 163 upstream commits, eight conflicts)
+
+- `package.json` still says 1.4.214, so the branch name repeats a fourth time.
+- `config/scripts/mobile-web-bundle-packaging-workflow-contract.test.mjs` — upstream deleted it
+  (#25791, "Remove low-value test inventories"). Took the deletion, so the fork's two workflow
+  entries in it are gone with it; the earlier note about re-adding them no longer applies.
+- `DiffCommentPopover.tsx`, `right-panel-comment-composer.tsx` — upstream #25480 swapped their
+  `<textarea>` for `ImeTextarea` (IME Enter no longer submits). Both boxes are the fork's
+  `ReviewMarkdownComposer` (TipTap), which has no textarea, so kept the fork's files whole.
+- `checks-panel/active-content.tsx` — the same #25480 import beside the fork's `useEffect`. Kept both.
+- `use-checks-panel-controller-state.tsx` — upstream dropped `panelVisibleSinceRef` /
+  `foregroundedUnrenderedReviewKeyRef`; the fork had dropped `commentsRef.current = comments` (the
+  comment list comes from `usePRCommentsState`). Dropped both.
+- `ui/textarea.tsx` — upstream added a `cell` variant beside the fork's `seamless`. Kept both.
+- `lib/worktree-activation.ts` — upstream moved the sidebar-filter lifting into
+  `worktree-activation-sidebar-filters.ts` (`liftSidebarFiltersHidingWorktree`). Took the move; the
+  fork's `revealTemporaryCheckout(state, wt)` now sits at the end of that function.
+- `ui-slice-preference-actions.ts` — upstream moved the agents-view defaults into
+  `createAgentsViewPreferenceActions`. Took it and kept the fork's
+  `createUiWorkspaceStatusRuleActions` import and spread.
+- Localization and RPC catalogs verified clean after the merge; no regeneration was needed.

 - `package.json` still says 1.4.214 after 780 commits, so the branch name repeats a third time.
