Founder request: bundle the finished Software Garden relay PRs so CI runs once while Actions is congested org-wide. Same pattern as cloud#4267.

Each one is merged unchanged with a merge commit, so the originals show as merged:

Each was reviewed and finished on its own PR: all checks green, 0 unresolved threads, and every bot finished on the head listed above. #1787 is intentionally excluded because it's parked on a design decision.

What the bundle adds on top

Review fixes on the bundle (all 43 bot threads answered and resolved)

The bots reviewed the full combined diff here; cubic had never reviewed the bot-authored originals. 36 findings are fixed, each with a fail-before/pass-after test:

  • Broker/PTY:
    • The PTY body cap applies only to PTY recipients; headless recipients are uncapped.
    • Muse gets its 16 KiB argv limit on CLI and node spawn, and can_inject waits for Muse's composer.
    • DECSET 2004 is detected across reads and only as a private-mode parameter.
    • An oversized wrap pointer falls back to a clipped envelope instead of requeueing forever.
    • An unlabelled delivery_verified event no longer claims echo.
  • MCP:
    • Idempotent replay is scoped to a digest of the acting agent token (identity + workspace).
    • Native tools send a tool-call idempotency key.
    • Retained keys expire lazily, with no timers.
  • CLI:
    • --task-file reads are bounded, and composed sandbox/auto-routed tasks are validated.
    • --wait-timeout is validated.
    • Removal-wait messaging and the no-workspace-key path are fixed.
    • Liveness evidence is ranked correctly and the hint is fleet-wide.
    • integration subscribe --list reads subscriptions once instead of per row.
  • Docs and tests:

7 are declined with code-cited replies on their threads: echo whitespace normalization (×2), the pre-existing Devin wait-mode gate, the fleet ack for uninjectable payloads, wrap paste-marker accounting, #1900's release wording, and generated trajectory records.

Local verification on this head

  • cargo test -p agent-relay-broker: 1441 passed (lib), plus all integration targets. The 5 spawner::tests::broker_hook_* tests only fail when the shell inherits the broker's attestation git-config env; all 30 pass with it unset.
  • cargo test -p relay-pty (CI skip list): 265 passed. cargo clippy -- -D warnings and cargo fmt --check are clean.
  • npm run typecheck is clean and npm run lint shows 0 errors. Vitest across packages/cli, harnesses and harness-driver: 2294 passed. The 1 failure there (broker-process.test pid timing) and 3 in sdk agent-relay.test fail identically on main in this environment. Prettier is clean on the changed files.
  • The fleet E2E and RelayFlow regression shards run only in CI.

Merging this supersedes merging #1913/#1910/#1900/#1893 one by one; they will be closed with a link here once it lands.

Note

High Risk
Changes core broker PTY injection, verified fleet spawn success criteria, and Devin startup gating—mistakes could block spawns, mis-report task delivery, or leave duplicate agents if operators retry unconfirmed spawns.

Overview
This bundle merges four relay fixes into one CI run: PTY task/message delivery, verified fleet spawn outcomes, Devin directory trust, and subscription/MCP idempotency (mostly documented in CHANGELOG.md; broker changes here center on spawn and injection).

PTY injection moves to shared injection_wire: bracketed paste when DECSET 2004 is latched (Devin always paste), typed fallback with ~1.5 KiB effective cap at default pace, 14 KiB body / 16 KiB envelope limits, control-character stripping, composer readiness waits (prompt_unproven), and pre-write injection_too_large rejection. Receipt for verified spawns is harness_acceptance only—echo, timeout fallback, and similar labels resolve as spawn_task_unconfirmed (live agent, do not retry) or spawn_task_failed when delivery clearly failed; failed tasks release the worker before reporting.

Fleet spawn tracks initial task event IDs and readiness order, rejects oversized PTY tasks before launch (headless/native exempt), and adds directory_trust_required for Devin after a 30s blocking trust prompt. Wrap delivers oversized relay messages as a bounded pointer instead of silent drop or infinite requeue.

CLI-facing behavior in the changelog includes --task-file, removal --wait, pending spawn evidence, and MCP/integration subscribe hardening. New broker integration tests cover Devin trust and Claude-style paste integrity.

Address the three P1 findings on PR #1893.

Endpoint anchors and a collapsed-paste marker were treated as positive
delivery confirmation, and the verified fleet spawn branch reported
spawned:true, ready:true without inspecting the verification label at
all. An agent that swallowed its whole task, received only its head and
tail, or echoed nothing produced the same successful spawn result as one
that received every byte.

Only whole-payload evidence confirms a delivery now: `echo` (verbatim)
or `echo_normalized` (verbatim once the TUI's wrapping whitespace is
removed from both sides, which replaces the head/tail `echo_anchors`
rung). Matching endpoints around an unobserved middle become
`echo_incomplete` and a collapsed paste stays `paste_summary`; both ack
the delivery without claiming receipt. A tail without its head still
fails with `echo_head_missing`, and an absent echo still reports
`timeout_fallback`.

`verification_label_confirms_receipt` is the single source of truth for
which wire labels count as receipt, kept in lockstep with
`EchoVerdict::confirmed` by test. A verified spawn whose initial task is
acked without it resolves as `spawn_task_unconfirmed`, which names the
live agent and warns against retrying (a retry duplicates the agent)
rather than reporting success or a retryable failure; the pending entry
is still retired so the readiness deadline cannot release a live worker.

Wrap keeps its failed-throttle policy on absent echoes and on evidence
of loss, but records a collapsed paste as unverified: that verdict
indicates nothing about loss, so it must not back the injection delay
off on every delivery to a paste-collapsing TUI.

Regressions: missing, changed and reversed anchors; a partial paste and
a redrawn earlier paste marker; label/verdict agreement; timeout
dispositions; runtime arms feeding timeout_fallback, paste_summary,
echo_incomplete and a missing label through the spawn-completion
handler. The PTY integration suite gains the reviewer's `middle_lost`
and `paste_tail` fixture modes as negative-confirmation assertions.

…the trust deadline

- relay-pty: add devin_trust_prompt_active(grid), true only when the trust
  question and choice are visible AND Devin's exact idle composer does not
  hold the cursor. A resumed screen that keeps an answered trust menu above
  the live composer no longer blocks readiness.
- broker: the startup gate and block-reason classifier use the grid-aware
  check; startup_gate_block_reason now takes the grid snapshot.
- broker: clear trust_first_seen whenever the gate is not
  DirectoryTrustRequired, so a returning prompt gets a full 30 s instead of
  inheriting a cleared prompt's deadline.

Regression tests fail before and pass after:
devin_trust_history_above_live_composer_does_not_block_readiness,
devin_trust_prompt_that_returns_gets_a_fresh_deadline,
devin_trust_history_above_live_composer_is_not_active.

…t; accept engine events

Devin review on #1910:

- Independent identical replies no longer collapse. Drop content-keyed
  coalesceWrite: MCP post_message and reply_to_thread go through
  McpRequestReplay.run keyed on the JSON-RPC request ID, accept an
  idempotency_key (forwarded to Relaycast, like send_dm), and bind the acting
  agent client before scheduling. Native host tools join only a replay of the
  same model tool call ID, which HarnessHost now passes to execute.
- integration subscribe validates --events against the engine's
  SubscribableEventTypeSchema (re-exported by the SDK as
  SUBSCRIBABLE_EVENT_TYPES) instead of a two-event allowlist, so
  action.completed, message.updated, etc. provision again.

Fail-before/pass-after tests: messaging-tools.protocol (parallel identical
writes stay separate; keyed retries join and forward the key; identity bound
at call time), request-replay, native-relay-tools (toolCallId keyed),
harness-host (toolCallId passed), integration-subscribe (engine events).

…t; don't report absent after a failed roster read

Review on #1900:

- Devin: a node heartbeat lists worker names, not the invocation that
  started them, so a pre-existing worker with the requested name made a
  timed-out (possibly rejected) spawn exit 0. The CLI and MCP recovery paths
  no longer convert heartbeat presence into success: the spawn stays
  spawn_pending (exit 8) with the liveness evidence and invocation ID, and
  the message says the listed worker may be an earlier one.
- Cursor: when the nodes.get/list scan throws, a later agents.get 404 no
  longer yields `absent` (which claims nothing was observed); it reports
  `unknown` with the roster read error.

README and CHANGELOG updated to match. Fail-before/pass-after tests in
spawn-liveness, fleet, and agent-relay-mcp.startup.

…n task failure, never drop oversized wrap messages

Review on #1893:

- Cursor (high): a task verdict that arrives before proven readiness
  (startup-fallback worker_ready releases the task first) is now recorded on
  the pending spawn, and the later proven worker_ready resolves the action
  from it, as success (whole-payload echo) or spawn_task_unconfirmed.
  Previously the verdict was ignored and the spawn timed out and was
  released after a successful delivery.
- Cursor (medium): a worker already ready when the launch returns had its
  PTY task queued unbound to the action; it now resolves as
  spawn_task_unconfirmed instead of plain success.
- Devin: a failed initial task (delivery_failed, or an immediate queue
  error) now expires the pending spawn with spawn_task_failed, so
  maintenance releases the worker and its fleet identity before reporting.
  A corrected retry can reuse the name.
- Devin: an oversized wrap message is delivered as a bounded notice naming
  the sender, size, limit and message ID instead of being silently dropped
  after it left the queue.
- Devin: `message post|reply|dm send` no longer apply the PTY injection cap.
  The limit stays at the PTY boundary (and on fleet task input).

Also merges origin/main, completing the PendingVerifiedSpawn literals both
sides extended, and fixes the two red checks this head caused:
- Fleet E2E resume: a verified spawn with a task now completes after task
  verification, and node-a's stub delays readiness 27 s, so the 30 s settle
  waits become 60 s.
- RelayFlow 1615: the fake Claude now redraws its prompt after Enter, as the
  real composer does, so the pre-write composer check can prove readiness
  for the second message.

Each new test fails with its fix reverted (mutation-checked) and passes
with it.

…ed tasks before launch; keep the reminder on rejection

Cursor review on #1893 (6ffef38):

- Body caps ignored the envelope. The PTY worker caps the formatted
  envelope at 16 KiB, but readTaskInput and queue_and_try_delivery_raw
  accepted a 16 KiB raw body, so a brief at the advertised limit launched a
  worker that then failed injection_too_large and was released. Bodies are
  now capped at MAX_BODY_BYTES (16 KiB less a 2 KiB ENVELOPE_RESERVE_BYTES)
  in the CLI and in raw delivery, and the fleet spawn action rejects an
  oversized task with spawn_task_too_large before registering or
  launching anything.
- The MCP reminder throttle was marked sent before the size gate, so a
  rejected envelope stole the reminder from the next delivery. It is now
  noted only after the envelope passes every pre-write gate.

Regressions (each fails with its fix reverted): the worst-case envelope
for a body at the cap fits 16 KiB (128-char names, workspace label, full
reminder); an oversized spawn task is rejected before registration; a
rejected injection leaves the next delivery its full reminder (real
broker integration test); the CLI rejects a 16 KiB task naming the envelope.

…before launch

Cursor review on #1893 (9dc1a75): the pre-launch check measured the raw
task, but spawn paths then append the exit-after-task contract, the relay
skill prefix and continuity context, so an accepted brief could still fail
at worker_ready, after launch.

validate_pty_initial_task_size measures the final task as it will be
injected and rejects it with spawn_task_too_large. It runs in
spawn_worker_from_request right after decoration (before any Relaycast
registration) and in WorkerRegistry::spawn_with_generation, the gate every
spawn path (HTTP, WS, fleet) funnels through, before anything is launched.
Muse takes its task in argv and non-PTY runtimes are not injected, so
neither is measured. One message builder (injection_wire::task_too_large_error)
backs every rejection.

Regressions: a fleet spawn whose raw task fits but whose exit-after-task
decoration overflows fails before RegisterAgent (fails with the new call
removed); the validator measures only injected PTY tasks.

…ed arm works on macOS

The fixture compares its trust record with os.getcwd(), which reports the
resolved path. On macOS the temp dir sits behind /var -> /private/var, so
the record never matched, the trusted arm showed the trust dialog, and
already_trusted_directory_becomes_ready_and_begins_task failed every time
on Rust Tests (macos-latest). Linux was unaffected.

…itial task completes

The resume scenario's `pool` harness runs the stub as `codex`, which sends
the initial task through the broker's chunked Codex path. That path confirms
delivery by watching the composer: each chunk rendered after the prompt, then
the composer cleared once Enter submits the turn. The stub only had the
kernel's cooked-mode echo and never cleared its composer, so after Enter the
task still looked parked; the broker retried the submit, exhausted its
retries and dead-lettered `initial_injection_incomplete`. On main that dead
letter was invisible because a verified spawn resolved at readiness. This
PR fails a spawn whose task was not delivered, so the scenario failed.

As `codex`, the stub now takes raw input, renders typed text after `›`, and
redraws an empty composer on Enter. Pre-ready input is still discarded and,
with raw mode, no longer echoed by the kernel either. Other stub uses are
unchanged. Verified locally against the CI-pinned engine: the resume
scenario now completes and resumes on its origin node.

RelayFlow regression case 1563-spawn-lifecycle-truth pins the MCP contract
for an accepted spawn whose outcome is unknown: code `spawn_unconfirmed`
and "Do not retry blindly". This PR had renamed that code to
`spawn_pending`, breaking that contract and any agent or tool keyed on the
existing code (Flows v2 shard 17).

The code is `spawn_unconfirmed` again on the MCP and CLI JSON. The new
behaviour stays: `state: "pending"`, exit 8, liveness evidence, inspection
and reclaim guidance. The message keeps "Do not retry blindly".

Headless providers receive the body as one argv entry, so dropping the PTY
envelope cap for them left an exec-time E2BIG instead of a clear error. They
now get the same portable 16 KiB ceiling as Muse. Also assert the headless
fleet-spawn test reaches registration, and reattach paste_mode_enabled's doc.

- Task size follows the resolved target: PTY keeps the 14 KiB envelope
  limit; Muse and the native runtime use the 16 KiB single-argument ceiling,
  including the bounded --task-file read.
- --task-file rejects malformed UTF-8 instead of substituting U+FFFD, and an
  oversized file is reported by size before decoding.
- --wait-timeout is floored to whole milliseconds and clamped to the timer
  limit.
- Spawn liveness reads the clock when judging a heartbeat, after the reads.
- MCP replay expires retained keys from a settlement-ordered queue instead of
  scanning every entry per call.
- Changelog: user-facing spawn-outcome wording; headless limit corrected.

Only the headless CLI runner (no harness config) passes a delivery to its
provider as argv; app-server and native harness workers receive frames, and a
native initial task is delivered the same way. The broker now bounds only that
runner, and the CLI no longer applies the 16 KiB argv ceiling to native-runtime
tasks (a 1 MiB read bound remains for --task-file). Changelog qualifies the
fleet spawn delivery guarantee to confirmed spawns and states --no-confirm.

The settlement-ordered queue relies on expiry order matching insertion
order; a backward wall-clock step could break that and keep a key cached
past its window. Use performance.now() for both creation and pruning.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Scope spawn replay entries by the acting identity.

When two identities use the same session and replay key, this call uses the default empty scope. The second identity can receive the first spawn result without starting its own spawn. Pass the scope from getAgentClient(as).

Suggested fix
-import { McpRequestReplay, withReplayScope } from './mcp/request-replay.js';
+import { McpRequestReplay, replayScopeOf, withReplayScope } from './mcp/request-replay.js';
...

spawn and add_agent still used the default empty replay scope, so a key
reused after register_agent moved the session default (or after switching
workspace) replayed another identity's spawn result. spawn is scoped to the
workspace key plus the acting agent token, add_agent to the workspace key.

@coderabbitai Re the outside-diff finding on agent-relay-mcp.ts (scope spawn replay entries by the acting identity): fixed in 290a30d. spawn is now scoped to a digest of the workspace key plus the acting agent token, and add_agent (which acts through the workspace client) to the workspace key. Test: scopes a retained spawn idempotency key to the acting identity (red before the fix: the second identity's spawn was replayed).

@AgentRelayBot Confirmed in 290a30dd6. spawn now uses replay scope derived from the workspace key and acting agent token. add_agent uses workspace-key scope.

The regression test checks that the same identity replays the retained result, while a changed identity starts a separate spawn. I inspected the code and test; I did not run the test.

This addresses the outside-diff finding. Thanks for the clarification.

Learning: In the TypeScript MCP implementation in packages/cli/src/cli/agent-relay-mcp.ts, retained `spawn` replay entries use `replayScopeForCredentials` with the workspace key and acting agent token, including an explicit `as` identity when supplied. `add_agent` acts through the workspace client and uses workspace-key-only replay scope. The regression test `scopes a retained spawn idempotency key to the acting identity` in packages/cli/src/cli/agent-relay-mcp.startup.test.ts checks that changing the session identity does not replay another identity's spawn result.

Learning: In the TypeScript MCP messaging implementation, clients returned by `getAgentClient` are tagged through `withReplayScope` in `packages/cli/src/cli/mcp/request-replay.ts` with a SHA-256 digest of their agent token. The token identifies both the acting agent and the workspace reached by the write. In `packages/cli/src/cli/mcp/messaging-tools.ts`, `post_message`, `reply_to_thread`, and `send_dm` bind the resolved client before replay and pass `replayScopeOf(client)` to prevent keyed results from crossing those contexts.

Merging trunk (which carries the v13.2.0 release) folded the bundle's 17
unreleased bullets into the released [13.2.0] section. Restore 13.2.0
verbatim from trunk and move them to [Unreleased - Minor].

- Roster-derived spawn liveness keeps a failed invocation read (readError).
- A late persona acknowledgement names the terminal parent invocation.
- Group-DM sendMessage accepts idempotencyKey in the thin-client type.
- Remove the now-unused validateInjectionSize.
- Docs: LF stays in typed-fallback payloads; e2e timeout comment corrected.
- Changelog: user-facing wording for delivery and pending-spawn bullets.
- Give the spawn replay-scope test an explicit budget for loaded hosts.

Brings in #1945 (harness-acceptance PTY delivery, submit-key resubmits,
file attachments) and resolves its overlap with the bundle.

Delivery verification: #1945's acceptance model replaces #1893's echo
verdict ladder for message delivery in pty_worker and wrap. A body echoed
in the composer can still be a parked draft, so echo content no longer
confirms anything; EchoVerdict, verification_timeout, the head-missing
check and wrap's echo-timeout re-injection are dropped with their tests,
and the integrity test fixture modes that only exercised echo verdicts
(tail, middle_lost, paste_tail, silent) go with them. Bracketed paste,
the 16 KiB cap, the wrap pointer for oversized messages, --task-file and
the Devin trust gate are kept.

Verified fleet spawn confirmation (#1893) keeps its frame-order handling
and spawn_task_unconfirmed result, re-pointed at #1945's labels:
- verification_label_confirms_receipt accepts only "harness_acceptance".
  Legacy "echo"/"timeout_fallback", "completed_replay" and an unlabelled
  frame resolve the spawn as spawn_task_unconfirmed. The spawn verdict is
  recorded before the PTY gate that turns non-acceptance labels into
  delivery_unconfirmed, so the action still resolves.
- A delivery_failed with "harness acceptance could not be proven" (window
  closed, body neither accepted nor parked) is not evidence of loss, so the
  spawn resolves as spawn_task_unconfirmed and keeps the live worker,
  instead of releasing it as spawn_task_failed. Every other failure reason,
  including "body remained parked after bounded submit-key recovery",
  still releases the worker and fails with spawn_task_failed.
- The label and reason are shared constants (HARNESS_ACCEPTANCE,
  HARNESS_ACCEPTANCE_UNPROVEN) used by pty_worker and the runtime.

MCP: send_dm uses the shared idempotencyKeyInput and replayScopeOf with
#1945's upload_file attachment wording. AGENTS.md follows main (trunk
gating removed). CHANGELOG unions both Unreleased sections. Protocol docs
and docs/harnesses/injection.md describe the acceptance labels and reasons.

Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
- PTY injection drops every control character except LF and tab, so a body
  cannot interrupt (Ctrl-C), kill or edit the composer line on either wire.
- Remove the unreachable second initial-Codex size check: the shared size
  gate already caps an initial Codex body at initial_codex_max_body_bytes.
- Spawn liveness: a heartbeat stamped more than 5s in the future is judged
  unknown rather than fresh, and an available node whose live-agent roster
  is missing or undecodable keeps a 404 registration read at "unknown"
  instead of "absent".
- Native send_dm joins a replayed tool call and sends a tool-call
  idempotency key, like post_message and reply_to_thread.
- --task-file keeps a leading UTF-8 BOM, as --task would.
- MCP spawn description names the pending shape it actually returns.
- Docs scope the 14,336-byte cap to PTY agents and describe control-byte
  stripping.
