-/**
- * Relay-side pty fd-leak patch for node-pty 1.1.0 (#17915).
- *
- * The app gets this through pnpm `patchedDependencies`; the relay installs stock
- * node-pty from npm onto the host, where no pnpm patch reaches. Stock 1.1.0 leaks
- * a pty fd on both Unix relay platforms, by two unrelated bugs on two code paths.
- *
- * Linux takes forkpty(), which has no atomic O_CLOEXEC, so every later child of
- * the relay -- pty children, git helpers, probes, agent CLIs -- inherits each live
- * master and keeps its /dev/pts device alive for the life of the relay (#8362).
- *
- * macOS takes pty_posix_spawn(), which opens up to three throwaway ptys to push
- * the real master off fds 0-2 and then never closes them: the cleanup loop is
- * `for (; count > 0; count--)`, but in any running process the first posix_openpt()
- * already returns >= 2, so the loop breaks with count == 0 and its body never runs
- * -- and where it does run it closes low_fds[count], never low_fds[0]. Measured on
- * darwin-arm64: one orphaned /dev/ptmx fd per terminal, never returned.
- *
- * macOS does not inherit the master into spawned children today, but not because it
- * is marked: FD_CLOEXEC is not set on it (`lsof +fg` shows R,W,NB, no CX). What
- * closes it is POSIX_SPAWN_CLOEXEC_DEFAULT in pty_posix_spawn's spawn flags, an
- * Apple-only flag that closes every fd in the child. That is one option away from
- * gone -- setting uid/gid drops libuv back to fork()/exec(), which honors nothing
- * but FD_CLOEXEC -- so the master is marked on the Apple path too, exactly as the
- * app's pnpm patch marks it. Windows has no fds and is excluded.
- *
- * The compile it buys differs by platform. Linux relays already run node-gyp at
- * install time (1.1.0 ships no linux prebuild), so this is a second compile on a
- * path that already compiles. macOS runs the shipped darwin prebuild and has no
- * build/ at all, so this is its first compile -- the price of the only fix there
- * is, since the bug is in the source that prebuild was built from.
- *
- * Non-fatal by construction: the working build is moved aside before anything is
- * touched and moved back on any failure, and a failed attempt drops a skip marker
- * so the compile is attempted at most once per relay directory.

-/**
- * Release the ConPTY teardown handles a relay's npm-installed node-pty never releases.
- *
- * Two files, and the ORDER of one of the edits is the whole fix.
- *
- * `windowsPtyAgent.js` -- `kill()` flips `readable` on both sockets and destroys neither.
- * `_cleanUpProcess` destroys `_outSocket`, so the conout handle comes back; nothing ever destroys
- * `_inSocket`, and it wraps a real Windows named-pipe handle from `fs.openSync(term.conin, 'w')`.
- * Every terminal leaks one File handle for the life of the host process.
- *
- * The obvious fix -- and the placement `config/patches/node-pty@1.1.0.patch` uses -- releases it at
- * the TOP of the branch, before `_getConsoleProcessList()` forks and before the native kill. That is
- * measurably worse than leaving the leak alone: teardown aborts partway, the forked console-list
- * agent is never reaped, and both pipe handles stay alive instead of one. This asset releases it at
- * the END of the branch instead, after the fork and the kill have already happened.
- *
- * Measured on a Windows SSH host, 20 spawn/kill cycles, handles bucketed by NT object type
- * (identical numbers standalone and through a real relay). Every row is the NON-DLL branch, which
- * is the branch a relay runs -- see the divergence note below for why that matters:
- *
- *   published node-pty        File +1/terminal,  Process flat
- *   desktop patch placement   File +2/terminal,  Process +1/terminal   <-- 3x WORSE
- *   released last (here)      File flat,         Process flat
- *
- * `windowsTerminal.js` carries the desktop's error-listener hunks verbatim. The conin listener is
- * what keeps a pipe error retiring one terminal instead of the host -- its own comment names the
- * failure mode: "Without a listener, Node promotes errors such as write EAGAIN to uncaughtException".
- * It is not what fixes the leak (adding it changed nothing on its own), but it is the guard that
- * makes destroying conin safe at all.
- *
- * Why this ships as a relay asset rather than only in config/patches/node-pty@1.1.0.patch: pnpm
- * patches do not cross the SSH boundary -- a relay host runs the tree `npm install` put there.
- *
- * DELIBERATE DIVERGENCE FROM THE DESKTOP, AND WHY IT IS NOT A DESKTOP-TERMINAL BUG: the two hosts
- * do not run the same branch of `kill()`. node-pty defaults `_useConptyDll` to false
- * (`windowsPtyAgent.js`). Every desktop site that opens a terminal pane sets it true --
- * `local-pty-utils.ts` (two) and `native-pty-spawn.ts` -- as does the `windows-conpty-warmup.ts`
- * warm-up, so all of those take the `else` branch, where UPSTREAM ALREADY destroys the input
- * socket. The relay passes no such option (`src/relay/pty-handler.ts`), so it takes the
- * `!useConptyDll` branch -- the one this asset and the desktop patch both edit.
- *
- * THE DESKTOP IS NOT ENTIRELY OFF THAT BRANCH. Two desktop sites omit the option and so run it
- * too: the hidden rate-limit probes in `src/main/rate-limits/claude-pty.ts` and
- * `codex-pty-rate-limit-probe.ts`. Both recur -- their fetchers poll -- and both tear down through
- * `kill()`, so this hunk is live on the desktop, just never for a pane a user can see. Do not
- * restate this as "the desktop never executes that branch": that sentence stood here for two
- * revisions and is false.
- *
- * What the numbers above therefore do NOT cover: they were measured on relay-style spawn/kill
- * cycles. Whether the early placement costs the same +2 File / +1 Process across a probe's
- * lifecycle is UNMEASURED -- plausible, not established, and worth measuring before anyone quotes
- * a desktop figure. What IS settled is the claim this comment replaced: that the desktop patch made
- * every Windows user worse off ON EVERY TERMINAL. Terminals take the DLL branch, and the harness
- * that produced that claim defaulted into the branch it was not trying to measure.
- *
- * The divergence is therefore about which branch each host runs for the workload that matters, not
- * about a regression in the terminals users open. The test still pins it, because a future "sync
- * the patches" would put the early placement onto the relay's branch, where it does cost +2 File
- * and +1 Process per terminal.
- *
- * If you extend this enumeration, grep for `node-pty` rather than for a static import: those two
- * probes were missed three times because they use `await import('node-pty')`.
- *
- * THE SELF-EXIT LEAK: FIXED FOR THE DESKTOP BY #18635, STILL LIVE ON A RELAY. A terminal that exits
- * on its own is also torn down through `kill()` -- both hosts call `destroy()` on natural exit and
- * `WindowsTerminal.destroy()` is `kill()` -- but the shell is already gone by then, so the ordering
- * this asset relies on does not hold. Measured over 20 self-exit cycles on the NON-DLL branch:
- * published +3 File/+1 Process per terminal, desktop patch placement +2/+1, this tree +2/+1. This
- * asset does not close it.
- *
- * #18635 does, in `config/patches/node-pty@1.1.0.patch`: the baton outlives the shell so `PtyKill`
- * still reaches `ClosePseudoConsole`, plus an unconditional conout dispose on the DLL branch. That
- * fix does not reach a Windows relay, and no hunk in THIS file can carry it, because it is mostly
- * NATIVE (`src/win/conpty.cc`) and this asset only rewrites `lib/*.js`. Three delivery paths exist
- * and none currently covers Windows:
- *
- *   - the pnpm patch does not cross the SSH boundary -- the remote `npm install` yields upstream's
- *     unpatched node-pty;
- *   - the orcad prebuild matrix now compiles win32 slots from patched source
- *     (`config/scripts/build-orcad-prebuilds.mjs`), but only standalone orcad consumes them;
- *     nothing ships them to a Windows relay host yet;
- *   - a relay asset CAN patch native source and rebuild on the host -- that is exactly what
- *     `node-pty-1.1.0-master-cloexec-patch.cjs` does -- but it returns
- *     `skipped:unsupported-platform` for anything but linux/darwin. Extending it to win32 means
- *     requiring an MSVC toolchain on the relay host, a far heavier precondition than on Linux,
- *     where node-gyp already runs at install time.
- *
- * So a Windows SSH relay still leaks a pseudoconsole per self-exiting terminal, and closing it is a
- * DELIVERY problem, not another hunk here. Do not read #18635's flat self-exit relay numbers as
- * covering deployed relays: they were measured against a locally rebuilt binary, so they describe
- * the relay CODE PATH on a patched tree, not the tree a relay host actually installs.

Restored panes, spawns without a command and the setting off make no dispatcher call; Codex in a floating terminal or a workspace subfolder is trusted at that folder, and every other preset at the workspace root.

An SSH launch returns the relay field for every preset and calls no writer, and the relay's pty.spawn starts no process until that launch's trust call settles. A home, a folder above one, a root, a symlink to a home and a missing path that climbs back to the home through `..` write no Claude, Copilot or Qoder trust file, on this machine and on the relay, and the home writes Codex, Cursor and Antigravity trust.",

Replace one retained fixed slot with an old-mtime same-owner directory while preserving the original, add a fixed-slot POSIX symlink, and require installed-path recovery to skip both while reclaiming a valid stale slot behind them. Add 15,197 unrelated relay-shaped names and run the real version GC, requiring bounded stdout and no removal. Unit and wire contracts cover exact POSIX and native PowerShell 0/1/7/8/9+ quota behavior, no-follow identity fencing, payload symlink/reparse rejection, one-item repeated draining, zero lock acquisition before upload settlement, joined transfer/channel teardown including never-settling failures, SFTP redirection, package.json namespace ownership, promotion only after the lock, cross-version isolation, and system-SSH behavior.",

A manual /compact only completes at an idle prompt, so it retires a subagent that exists ONLY as a disk snapshot; live evidence -- a child observed in this runtime, an unclassifiable running background task, a registered session cron -- still holds the pane at working. A completion requires a valid provider prompt UUID, matches the pane owner by connection and provider session -- except on a restored row, which carries the previous connection and may carry no session at all -- and is applied at most once per compact. Ownership is enforced by the client that owns pane identity; a relay forwards and defers, so a cold relay cache cannot swallow the clearing event. A relay predating this contract forwards its own mapping, so ingest drops automatic envelopes, stamps the boundary on manual ones, carries the summarized turn label onto a promptless completion with or without a trigger, and classifies a trigger-stripped replay by payload state while still enforcing ownership.

Hold an old relay unsubscribe, queue one same-root setup leader and one anchor, then abort 10,000 joiners; require every cancellation to settle before teardown releases, exactly one anchor waiter, and only one later physical install. Advance the former paired-web callback deadline while capacity remains full, require cancellation ownership to stay live, publish the server token before ready, and require files.unwatch to abort setup before a later slot release can install a native root. Reject the first ready-watch unwatch with a physical-exit promise, resolve that exit later, and require a fresh physical unwatch attempt, registry release, and exactly one stream end. Fill one healthy shared child with multiple roots, map a standard SSH repository's base, Git common directory, and worktree roots to one relay supervisor, then inject IPC disconnect-before-exit, queued and active cancellation, operations during termination, kill-without-exit, repeated unkillable generations, initial and recovery timeouts, and shard failure. During local and SSH deletion, attempt a late terminal spawn whose worktree identity and cwd name different roots, enumerate a non-prefix remote PTY by authoritative worktree ownership, withhold daemon/relay exit callbacks, make attach positively prove a concurrent-shutdown PID dead, and make the provider unavailable; require every acquired admission to roll back on rejection, dead-PID proof to settle physical exit before reaping, timeout to retain ownership, and Git/filesystem deletion never to start. Require bounded watcher process count, physical-exit settlement, healthy-root recovery, stale-generation rejection, overflow plus later events, and fail-closed destructive cleanup. Verify relay build hashes and remote install probes require both relay.js and relay-watcher.js.

-//
-// Deliberately absent, and therefore still covered by no CI trigger:
-//   ssh-docker-relay-perf.spec.ts — wall-clock latency thresholds; flaky budgets here would
-//     cost the lane its credibility. NOTE: a runner script test:e2e:ssh-docker-perf exists in
-//     package.json but NO workflow invokes it, so this spec currently runs in no CI lane at
-//     all. Recorded as a real gap, not as coverage living somewhere else.
-// The bulk-open frame probe runs headed: headless Linux compositing schedules idle RAFs
-// roughly 1s apart, so it cannot measure foreground interaction against the same budget.
-//
-// Why both projects: ssh-port-forward-lifecycle is @headful, which the headless project
-// grep-inverts away.
-//
-// Known gaps in SSH e2e coverage, recorded here because nothing else names them:
-//   - E2E does not gate merges: `verify.needs` in pr.yml omits `e2e` while the suite is red on
-//     main. Nothing in this lane blocks a PR yet. pr.yml's Require-successful-checks comment
-//     has the exact wiring to flip it, and the gate contract asserts the current state.
-//   - Two specs are gated on env vars no workflow sets, so they run nowhere
-//     and are not Docker-gated, which puts them outside this file's contract:
-//       nested-runtime-ssh-lifecycle, nested-runtime-ssh-routing (ORCA_E2E_NESTED_RUNTIME_SSH)

+# Sync notes: stablyai/orca `main` into `fork-main` (2026-10-11b)
+
+Branch: `sync/upstream-2026-10-11b` from `origin/fork-main` (`079420eab9d`).
+Merge: `upstream/main` @ `92fb883cf25` (`git merge --no-ff`).
+At launch, fork-main was 105 behind / 626 ahead of upstream/main.
+
+This is a follow-up to PR #17 (`sync/upstream-2026-10-11`). Do not merge this
+PR. Do not cut tags. Do not touch Coolify.
+
+## Policy
+
+- Keep fork features listed in `config/fork-features.yml`.
+- Re-apply #15/#17 resolutions where upstream re-touched the same files.
+- Upstream wins for files the fork does not customize.
+- Allowlisted auto-resolves: `.gitignore` union (drop leftover orphan comments).
+
+## Conflict resolutions (7 paths)
+
+### `.gitignore`
+
+Union of ours and theirs. Dropped two orphan comment lines left from the
+previous union (`# Local-only design/planning docs…` fragments). Kept
+upstream's new ignores:
+
+- `.build/preflight-benchmark/`
+- `.local/static-analysis-research/`
+
+### `config/scripts/pr-e2e-gate-contract.test.mjs`
+
+Took upstream. Upstream removed the Docker-SSH source-routing tests along with
+`hasSshSourceChange`, `SSH_SOURCE_ROUTE_IDS`, and the
+`ssh-docker-watcher-isolation` job (`ff27338299e`). The fork-only edit in those
+tests was `changed-e2e` timeout `>= 45` → `>= 60`; that assertion lived only
+inside the deleted tests, so it cannot stay. The 60-minute shard still lives in
+the workflow.
+
+### `src/shared/protocol-version.ts`
+
+Kept the fork spread `...FORK_TERMINAL_AND_AGENT_LAUNCH_RUNTIME_CAPABILITIES`
+(terminal navigation/question + `automation.agent-flags.v1` + upstream
+`AGENT_LAUNCH_RUNTIME_CAPABILITIES`). Added upstream
+`SSH_TARGET_MANAGEMENT_RUNTIME_CAPABILITY` (`ssh.target-management.v1`).
+
+### `src/renderer/src/components/sidebar/RemoteFileBrowser.tsx`
+
+Kept the fork `local?: boolean` in-app picker (Linux GTK-less browse). Kept
+optional `targetId` + `runtimeEnvironmentId` so both may be set (upstream:
+server's own SSH host). Did not take upstream's exclusive union, because
+`CreateProjectLocationField` passes `local={local}` with possibly undefined
+ids.
+
+### `src/renderer/src/components/sidebar/use-remote-file-browser-listing.ts`
+
+Combined:
+
+1. `local` → `repos.browseLocalDirectory` (fork)
+2. both ids → `browseRuntimeSshDirectory` (upstream, server dials its SSH host)
+3. `targetId` only → `ssh.browseDir` (this client's SSH host)
+4. otherwise → `browseRuntimeServerDirectory`
+
+### `src/renderer/src/components/sidebar/use-remote-file-browser-listing.test.ts`
+
+Add/add: kept upstream happy-dom `renderHook` cases for server-owned SSH vs
+client SSH vs server disk, plus the fork local-directory case.
+
+### `tests/e2e/helpers/electron-process-shutdown.unit.test.ts`
+
+Kept both:
+
+- fork `readDaemonPidFiles` JSON/legacy pid-file cases
+- upstream POSIX `cleanupE2EDaemons` SIGTERM/SIGKILL/descendant cases
+
+## Auto-merged fork semantics kept
+
+- `pet: 'host'` in `HOST_OPERATION_OWNERSHIP` (covers `pet.speak.*`)
+- `AUTOMATION_AGENT_FLAGS_RUNTIME_CAPABILITY` in
+  `automation-runtime-capabilities.ts` and the fork protocol spread
+- automation-run open/resume/workspace-action (no upstream commits on those
+  files in this 105-commit window; auto-merge kept fork)
+
+## Light local checks (this box, via `heavy-run`, glibc Node 22)
+
+- `tsc --noEmit -p config/tsconfig.tc.cli.json`: clean.
+- vitest `--maxWorkers=1`:
+  - `pr-e2e-gate-contract.test.mjs` + `host-operation-ownership.test.ts`: 29 passed
+  - `electron-process-shutdown.unit.test.ts` + `repo.test.ts`: 34 passed
+  - `runtime-ssh-target-management.test.ts`: 13 passed
+  - `use-remote-file-browser-listing.test.ts`: local transform failed to resolve `@/runtime/...` aliases (same class of local alias miss as `AddRepoSteps.default-checkout.test.ts` → `@/i18n/i18n`). Not treated as a merge defect; GitHub CI runs the full vitest config.
+- Full `pnpm tc` (node+web) and electron-builder not run locally.
+
+## CI follow-up
+
+`test / tests node 24 5/5` failed on `node-server-change-scope.test.mjs` (7 cases).
+Cause: upstream `#27215` removed `src/relay/` from `CROSS_HOST_PREFIXES` and did not
+move the change-scope fixtures off `src/relay/…`. Pointed those fixtures at
+`src/main/ssh/` (still a cross-host prefix). Local vitest: 98 passed.

- * Why this exists: the remote scanner had no cache of any kind, so every pass
- * re-read and re-parsed the whole corpus — up to 3000 whole-file reads, GBs of
- * JSONL, including July transcripts that had not changed in a month — which is
- * what pegged the relay host on the renderer's 30s forced-rescan cadence
- * (#13753). The local scanner has had `parseAgentSessionFileCached` for exactly
- * this reason; this is its remote counterpart.
- *
- * `(mtimeMs, sizeBytes)` covers the transcript, and the sidecar observation
- * discovery records beside it (remote-session-scanner-discovery.ts) covers a
- * source's companion file, so a metadata-only transcript whose companion
- * changed still looks changed. Remote Cline is the only such source; remote
- * Cursor streams transcript content with no sibling to read. Sources whose
- * parse reads a file discovery does not stat — Codex looks its title up in
- * `session_index.jsonl` — are not covered by either and pass
- * `refreshReusedSession` to re-derive the uncovered part without touching the
- * transcript.
- *
- * Only a completed parse is stored. A read that threw stays uncached so a
- * transient filesystem failure cannot pin a wrong answer for the corpus's life.

- * Host-keyed provider dispatch: one entry per execution host kind, with `local` among them.
+ * Host-keyed provider dispatch: one route per execution host kind, `local` included.
  *
- * The incumbent spelling across main is `const c = repo.connectionId; c ? sshProvider(c) : local()`,
- * where `null` means *both* "resolved: this is local" and "could not resolve". Every path that
- * cannot determine the host therefore answers "local" and runs remote work on the client — the
- * #11163 defect class, which has produced a reproduced cross-host leak (an `ssh:` worktree
- * resolving to another target) and near-misses where a transcript that exists only on a remote host
- * would have been read locally. The shape also cannot express a `runtime:` host at all.
+ * The input is an `ExecutionHostId`, never null, and an id that names no host throws instead of
+ * degrading to `local`, so work whose host is unknown never runs on this client (#11163). The
+ * resolution layer (`getRepoExecutionHostId`, `getWorktreeExecutionHostId`,
+ * `resolveWorktreeExecutionHost`) reports `unresolved` as its own verdict.
  *
- * This module removes that spelling. Its input is an `ExecutionHostId`, which is never null, and an
- * id that names no host throws instead of degrading. `getRepoExecutionHostId` /
- * `getWorktreeExecutionHostId` / `resolveWorktreeExecutionHost` are the resolution layer that feeds
- * it; the last one already answers `unresolved` as a distinct verdict rather than "local".
- *
- * Why a route union rather than a uniform `getGitProviderForHost(): IGitProvider`:
- *
- *   - `local` git and filesystem work takes per-worktree execution options (`wslDistro`,
- *     `sharedLinkPaths`, admission tier). A registered stateless provider would silently drop WSL
- *     routing, so the local git and filesystem routes carry a factory that is built per call.
- *   - `runtime:<env>` is never executed in this process; it is forwarded to that server, which
- *     treats it as its own `local`. A runtime repo's `connectionId` names the *server's* SSH target,
- *     so handing it to this client's SSH table would dial a same-named target on the wrong host.
- *
- * So each host kind is its own variant and callers switch exhaustively; `runtime` cannot collapse
- * into `local` by omission.
- *
- * Inside the `ssh` variant, `provider: null` means "remote and currently unreachable", never
- * "local" — loss of contact is never evidence of locality (the `live` / `unverifiable` / `exited`
- * rule in AGENTS.md).
+ * Each kind is its own variant so callers switch exhaustively:
+ *   - `local` git and filesystem routes carry a per-call factory, because they need per-worktree
+ *     options (WSL distro, shared links, admission tier) a shared provider would drop.
+ *   - `runtime:<env>` is forwarded to that server. Its repo's `connectionId` names the server's SSH
+ *     target, so it must never reach this client's SSH table.
+ *   - `ssh` with `provider: null` means "remote and unreachable", never "local".

- *
- *  `expired` is separate on purpose. It is written by four paths, and every one of them
- *  deliberately leaves the remote process running: a pane re-leasing under a new relay id, a pane
- *  surface missing from the layout, a retired reattach, and a reattach the HOST answered "not
- *  found" for. Only the second of those is reached with the process provably alive — the layout
- *  refusal runs after `pty.attach` already succeeded (`restoreReattachedPtyRuntime`), which is
- *  precisely why its own comment reads "topology absence alone is not authority to kill a
- *  process". A reattach that failed on the transport writes nothing at all: it early-returns as
- *  `reattachAttemptsExhausted` and the lease stays `attached`, hence routed.
- *
- *  Folding it into `routed` would work, but it would also lose the reason in the skip log, and this
- *  is the distinction the sweep most needs to be able to explain.
- *
- *  Deliberately the raw state rather than `sshRemotePtyLeaseAllowsReattach`: that predicate answers
- *  "may this lease be reattached", and this asks "may this client stop the process". Every non-
- *  `terminated` state answers no either way, so sorting the marked leases (`supersededBy`,
- *  `relayIdRecycled`) into `routed` instead would move nothing but the skip reason — and both marks

- * Point node-gyp at the headers the host's Node install already ships, so compiling node-pty

- * Why: node-pty has no Linux prebuild, so every Linux relay compiles it, and node-gyp's default
- * is to download `node-v<ver>-headers.tar.gz` before configuring. Every official Node build, and
- * every version manager that unpacks one (nvm, fnm, volta, mise, n), already has those exact
- * headers at `<prefix>/include/node`. The download was the only step that needed the internet,
- * so a firewalled host failed with ECONNREFUSED on work that never had to happen (STA-6674).
- *
- * Why both variables: node-gyp >= 11.4 prefers `npm_package_config_node_gyp_<key>` and npm 11+
- * warns that arbitrary `npm_config_<key>` is deprecated, but node-gyp 10 (bundled with Node 20)
- * reads only `npm_config_<key>`. Both together cover every Node the relay runs on.
- *
- * Why the version check: node-gyp trusts `nodedir` blindly, so a distro `/usr/include/node` left
- * by an older headers package would be compiled against as-is. Whether that binding then misbehaves
- * is not established (one measured run loaded a node-20-header build under node 24); refusing is
- * the conservative default. A mismatch leaves the variables unset, which is today's path.

- * Installs Orca's own ripgrep on an SSH host so remote Quick Open and text search do not depend

- * `~/.orca-remote/ripgrep/<content-hash>-<platform>/rg[.exe]`, a sibling of the
- * `relay-<version>` dirs keyed on the binary's bytes alone, so a relay upgrade never re-uploads it.
- *
- * Uploads land in a private `.upload-<token>` stage and are renamed into place only after a size
- * check, so an interrupted or concurrent deploy never leaves a truncated binary at the final path.
- * Ordinary failures use the relay's PATH `rg` and git/readdir fallback; unconfirmed remote stops
- * propagate so deployment cannot start more work while the previous operation may still run.

- * A shared dir used to mean a shell could read one build's `.zshenv` and
- * another's `.zprofile`/`.zshrc`/`.zlogin`, which is why every generated file
- * redefined the helpers it called. #15285 removed the hazard for the desktop and

- * never write the same directory.
- *
- * The relay is the one writer left on a fixed path — `~/.orca-relay/shell-ready`
- * — so this is where the scenario is still reachable, and it is now much smaller:
- * Orca writes one file, and that file hands ZDOTDIR back before anything else
- * runs. Both halves are pinned here:
- *
- * 1. Files an older build left beside the hook are inert — zsh reads .zprofile,
- *    .zshrc and .zlogin from the user's own directory and never from here.
- * 2. Generation does not delete them. An older build checks for all four before
- *    calling its tree complete; deleting them makes it rewrite its own `.zshenv`
- *    over ours, and an older `.zshenv` points ZDOTDIR at a directory that would
- *    then hold no `.zshrc` at all — the user losing their entire config, which is

-/**
- * Single-flight coordinator for fs.listFiles full-tree scans (#7721).
- *
- * Why: rapid workspace switching used to stack N concurrent full-tree scans
- * on the single-threaded relay and its one SSH channel, starving small
- * interactive fs.readDir/fs.stat requests past their 30s timeout. This
- * coordinator guarantees at most one scan in flight per client:
- *   - a request for the same root/excludes joins the in-flight scan
- *     (Quick Open + file-explorer filter share one scan),
- *   - a request for a different root supersedes it — the old scan is aborted
- *     and its request fails fast instead of running to completion (this also
- *     protects against older Orca clients that never send rpc.cancel),
- *   - when every joined requester cancels (rpc.cancel / client detach), the
- *     scan is aborted so abandoned work stops immediately.

- * Regression: SSH typing latency under bulk file-stream load.
- *
- * The relay and the client share ONE ordered SSH channel. If the relay
- * enqueues an entire file's fs.streamChunk frames into the outbound pipe
- * at once, an interactive pty.data echo emitted mid-stream queues behind
- * megabytes of bulk data and typing feels seconds-slow.
- *
- * These tests model the SSH channel as a congestible in-memory pipe and
- * assert deterministic byte bounds instead of wall-clock latency:
- *  - with a saturated sink, the relay stalls the pump on write backpressure
- *    so at most ~1 chunk frame sits ahead of a pty echo;
- *  - with a fast sink but an unresponsive client, the fs.streamAck credit
- *    window bounds the in-flight backlog;
- *  - legacy clients that never ack still receive the full stream.

- * routed the SSH removal through prune-and-retry while the local removal gave up
- * and preserved the branch.
- *
- * These tests push the same failure through both published removal entry points —
- * `removeWorktreeOp` (what `git.removeWorktree` runs on the host) and `removeWorktree`
- * (the local runner) — and require the same branch-deletion commands and the same

-/**
- * Regression: SSH typing latency under large git responses.
- *
- * The relay and the client share ONE ordered SSH channel. A large git diff/exec
- * response sent as a single JSON-RPC frame queues megabytes into the outbound
- * pipe at once; an interactive pty.data echo emitted mid-response then sits
- * behind all of it and typing feels seconds-slow.
- *
- * These tests model the SSH channel as a congestible in-memory pipe and assert
- * deterministic byte bounds instead of wall-clock latency:
- *  - WITHOUT the fix (client does not opt in), the whole response queues ahead
- *    of a pty echo;
- *  - WITH the fix (client opts in), the response streams on the bulk lane and
- *    at most ~1 chunk frame sits ahead of the echo;
- *  - both paths reassemble the identical git result.

-/**
- * Gather the evidence a node-pty spawn failure needs, on the host that failed.
- *
- * Three sources, because no single one is sufficient:
- *
- *  1. What is on disk where node-pty's loader looks, and what node-gyp recorded it was
- *     configured for (`build/config.gypi`). This answers "wrong ABI / wrong arch" even
- *     when the loader said nothing useful, and it is the only source available when the
- *     binding is absent entirely.
- *  2. The dynamic loader's own words, recovered by dlopen'ing the file node-pty would
- *     have opened. node-pty's loader rethrows only its LAST attempt, so the real message
- *     is otherwise destroyed before the relay sees it. This runs in a CHILD process: a
- *     binding that aborts inside the loader would take the relay down with it, and a
- *     relay that dies is a reconnect loop rather than an error message.
- *  3. The host's C/C++ toolchain, but only when nothing was compiled — "install
- *     build-essential" is the right answer for a compile that never ran, and noise for a
- *     binary that exists and is simply wrong.
- *
- * Every step is best-effort and failure-tolerant: whatever cannot be established is
- * reported as unestablished rather than guessed (docs/reference/ssh-execution-boundary.md).

-/**
- * Why the remote host cannot spawn terminals, in terms the user can act on and check.
- *
- * The relay used to answer this with one hedged paragraph — "install build tools, or
- * else reconnect, or else check your Node version" — because the only thing it looked at
- * was that `require('node-pty')` threw. That paragraph names three different remedies for
- * four different faults and lets the user verify none of them.
- *
- * node-pty's own loader is why the raw cause went missing: it walks build/Release,
- * build/Debug and prebuilds/<platform>-<arch>, then rethrows only the LAST error. So a
- * `pty.node` the dynamic loader refused arrives as `Cannot find module '../prebuilds/…'`,
- * and the GLIBC/ABI/arch sentence that actually says what is wrong is discarded before
- * the relay ever sees it. Recovering it needs a separate dlopen of the file the loader
- * would have opened — see node-pty-binding-survey.ts.
- *
- * Everything here is pure so every verdict is testable from a host that is none of the
- * hosts that break. `unverifiable` is a first-class outcome: a probe that did not answer
- * is not a diagnosis (docs/reference/ssh-execution-boundary.md).

- * cadence, and the fork was neither cached nor coalesced. procps-ng opens six
- * procfs files per process to resolve a ppid — including a `/proc/<pid>/ctty`
- * that never exists on Linux — so one call cost O(host process count) syscalls,
- * ~4k opens per pgrep on a 690-process host, at up to 8 forks/sec (#13537).
- * `getForegroundProcessName` in the same RPC already captured the TTL-cached
- * `ps` table, whose index carries the parent/child map, so the answer is free.
- *
- * `fresh` opts out of that TTL. A poll can read a 500ms-old table because its
- * next tick corrects it, but a close or cleanup decision acts on the answer
- * once and destructively — a child that started inside the TTL would be killed
- * with no confirmation. `pgrep` scanned per call, so anything that decides
- * has to keep scanning per call.

- * directory was meant, so substituting `$HOME` for an agent is the damage this refuses to do.
- *
- * That refusal is only sound when the relay's own filesystem is the one the spawn will use. A WSL
- * shell hands execution to a guest, and a guest path never stats on the Windows relay, so

-/** Which relay PTYs a client may prove it orphaned, and therefore may stop (#9819).
- *
- *  A relay PTY is a child of the detached relay daemon. Stopping one destroys a running process —
- *  often a running agent — on the user's remote machine, and the relay's 50-slot cap is a far
- *  cheaper failure than that. So every rule below is written to answer "can this client PROVE
- *  nobody owns this?" and to answer "no" whenever it cannot.
- *
- *  The rule #9819 proposed — "pane-bound and the app no longer owns or leases it" — is not that
- *  proof. Absence from a client-side set is `unverifiable` by construction
- *  (`docs/reference/ssh-execution-boundary.md`): a second machine running the same Orca build
- *  connects to the SAME relay and displaces the session owner, and its PTYs are missing from THIS
- *  client's store for exactly the same reason a genuine orphan is. Sweeping on local absence alone
- *  would let one laptop reap another laptop's live agents.
- *
- *  What replaces it: the host itself records which authenticated consumer identity asked it to
- *  create each PTY, and publishes that back. A PTY is sweepable only when the OWNING HOST names
- *  this client as its creator and this client's own durable state has no route to it. Both halves
- *  are required; either alone is a guess.

-/**
- * The two regressions this covers both shipped and both reached a user, because nothing here
- * asserted what a pane actually SHOWS after a reconnect:
- *
- * 1. Panes came back blank. The relay treated the reconnecting client as one that already held the
- *    stream and returned no scrollback, while the renderer had disposed the xterm with its buffer.
- * 2. A tab created afterwards came up with no prompt and stayed generically titled, because the
- *    reconnect prepaint could still fire on a spent mount.
- *
- * Reading the pane's own text is the point. Asserting a pty id, a status, or a spy call is what let
- * both of these through: every one of those was correct while the screen was wrong.
- *
- * KNOWN: (1) is fixed at the symptom. requireReplay makes the client ask for what the relay wrongly
- * decided it did not need. Three attempts at the cause failed, and the reasons are worth keeping
- * because each looks correct until you run it:
- *
- * - RETIRING THE DELIVERY ON dispatcher.onClientDetached, the way fs-handler, git-handler and
- *   relay-filesystem-watch-registry release their per-client state, BREAKS CHECKPOINT RECOVERY (10
- *   tests in relay-pty-source-recovery-interleavings / restore-retry). A delivery outliving its
- *   client is deliberate here: it is what lets a reconnecting client resume from a checkpoint
- *   instead of re-receiving everything. This class omits that subscription on purpose.
- * - RETIRING WITHOUT session.cancelDelivery() orphans the credit ledger's one-upstream-owner-per-pty
- *   slot, and the next open throws "PTY source delivery already has an upstream owner". Seen live as
- *   an error toast and a blank pane.
- * - COMPARING record.identity.clientGeneration TO THE REQUEST is not available: that value is
- *   client-supplied through pty.openClient (see admitsPtyDataPublication in
- *   dispatcher-capacity-signals.ts) and RequestContext carries no generation of its own.
- *
- * The real cause is now established, and it is broader than this spec: a reconnect reuses the same
- * clientId (setWrite keeps the primary client), so the relay's activate() matches on it and returns
- * 'existing' before ever reaching the recovery branch. Checkpointed source recovery therefore has
- * never run on an SSH reconnect at all, and the byte tail is not a fallback but the only path. Full
- * chain and the fix it implies: docs/reference/ssh-reconnect-source-recovery.md.

- * The live incident (Orca 1.4.198, 2026-09-05): both relay processes SIGSTOPped for 20 s, then

- * had already rewritten the endpoint credential, and the surviving daemon then refused every
- * client forever — "Endpoint credential mismatch" every ~20 s with a PTY and zero clients, until
- * someone sent it SIGTERM by hand.
- *
- * Three things must hold after the same injection here. The credential file is byte-for-byte
- * and inode-for-inode what it was, because only a daemon that owns the socket may write it. The
- * same daemon still owns the socket, because a relay that merely went quiet is `live`, not
- * `exited`, and is never replaced (docs/reference/ssh-execution-boundary.md). And the relay log
- * has no mismatch line at all, because the wedge is gone rather than healed after the fact.

- * Adversarial resource-accumulation probe for the SSH relay.
- *
- * Covers claims no unit test can reach, measured on the remote host itself:
- *  - #17914 / #17920: PTY master fds are close-on-exec, so /dev/pts and the
- *    relay's fd table must not grow per terminal beyond the terminals
- *    themselves. #17914 patches the app and terminal daemon; the relay installs
- *    node-pty from npm on the remote host, so #17920 ships the same patch as a
- *    relay asset and rebuilds there. Only a remote host can judge that second
- *    half, which is why leakedMasterFdCount is measured on the container.
- *  - #17817/#17821/#17831: repeated disconnect/reconnect must not accumulate
- *    relay processes, orphan PTYs, or fds.
- *
- * Requires: ORCA_E2E_SSH_DOCKER=1 and Docker available.

-/**
- * Every existing reconnect spec reconnects by calling ssh.disconnect() then ssh.connect() — a
- * clean, client-initiated cycle that the client knows is coming. Nothing covered the fault the
- * reconnect machinery actually exists for: the transport dying underneath a live session, with the
- * remote still running and still holding the PTYs.
- *
- * The distinction matters because the two paths diverge at the relay. A graceful disconnect closes
- * the client cleanly; a killed connection leaves the relay's grace window and PTY table intact, so

 /**
  * A relay-era SSH host converts to managed orcad on connect (#24979), on a real host:
  *
- * 1. Without an orcad template the connect keeps the relay, so the host gains relay-era state: a
- *    repository, a folder workspace, an editor tab, and a relay terminal that has exited.
- * 2. With the template in place and no relay terminal running, the next connect converts it, and
- *    the new server lists that repository and folder and the editor tab.
- * 3. The source rows stay retained and hidden (downgrade safety), across a later connect too:
- *    nothing deletes them automatically.
+ * A relay-era profile (repository, folder workspace, editor tab) converts on its first connect,
+ * and the new server lists them. The source rows stay retained and hidden.
  *
  * A managed host also updates to a relaunched app's bundled orcad on its next idle connect, and
  * reaches its server when another runtime already holds orcad's preferred port.

-/**
- * An SSH reconnect destroys the terminal state behind a tab whose creation has not yet reached the
- * host, while the process it was running keeps going.
- *
- * The symptom is worse than a disappearing tab, because the two models disagree: the TAB BAR still
- * renders the tab, correctly titled, but the terminal slice holds only the older tab and no pane
- * manager exists for the newer one. So the user is left clicking a selected tab that will never
- * paint, with no error and no way to recover it, while `top` runs on untouched on the host.
- *
- * Mechanism:
- * - `remote-workspace-session-merge.ts:86-89` builds `tabsByWorktree` as
- *   `{...omitTargetWorktrees(current), ...remote}`. A local tab for the target worktree that is
- *   absent from the host snapshot has no surviving branch — it is simply not in the result.
- * - `remote-workspace-target-sync.ts` applies that host snapshot unconditionally once
- *   `revision > 0`, without pushing local state first.
- * - The upload that would have put the tab in the host list is DROPPED rather than deferred: the
- *   debounced session writer is gated on `!isRemoteWorkspaceSnapshotApplyInProgress()`, and
- *   `REMOTE_WORKSPACE_SNAPSHOT_WRITE_SUPPRESS_MS` is 1_000 after a snapshot apply. A tab created
- *   inside that window never gets written.
- *
- * Correlation observed across runs, which is what pinned the mechanism: host snapshot revision 1
- * (1 tab) always lost the pane; revision 2 (2 tabs) always kept it.
- *
- * PRE-EXISTING. None of remote-workspace-target-sync.ts, remote-workspace-session-merge.ts,
- * use-app-session-persistence.ts or remote-workspace-snapshot-apply.ts was touched by the branch
- * that added this spec.
- *
- * FIXED by making the merge treat the host as authoritative only for what it knows: a local tab the
- * snapshot has never been told about is kept rather than erased.
- *
- * SCOPE — this spec is NOT the guard, and measuring it is the only reason that is knowable. Against
- * the unfixed code it fails roughly one run in three or four, because the destruction needs the tab
- * to be created inside the debounced upload's suppression window and nothing here can force that
- * from the outside. Removing the waits between creating the tab and reconnecting tightened it and
- * still did not make it deterministic.
- *
- * The real guards are deterministic and live elsewhere: remote-workspace-snapshot-local-tab-survival
- * .test.ts drives this same scenario through the actual apply path, and
- * remote-workspace-session-merge-local-survival.test.ts covers the merge decision table. Together
- * they fail 8 times on the unfixed code. Keep this spec as end-to-end smoke, and do not read a green
- * run here as evidence the bug is gone.

- * update, which is what the user did) and read the stub agent's argv ledger out of the container.

- *  - matching stamp → the ledger must contain `--resume <id>`.
