Problem

After a Codex turn finished in T3, an external codex queue message ran in T3’s app-server but its prompt, reply, tools, and requests never appeared in the thread. Reproduced on Linux with Codex 0.163.0: T3 stayed at READY while the native log recorded QUEUED and completion.

Change

Recognize externally started turns on known root Codex threads, hold their frames, and wake the existing continuation path. The resulting run adopts the native turn instead of starting another one. Replay preserves notification order and lets requests receive user responses without blocking startup. Rejected or cancelled wakes release buffered requests and reject later requests until native completion.

Scope and approval

Fixes #23919
GitCafe: #23919

Triaged bug via the automated issue flow. This restores recording of work already running in T3’s Codex process. No settings, persisted fields, or client contracts change.

Verification

  • Red-first replay reproduced the dropped QUEUED output. Added focused coverage for adoption, approvals during startup, command-shaped prompts, rejected/cancelled wakes, terminal callbacks, and approvals arriving after rejection.
  • After integrating current main, vp test run src/orchestration-v2/Adapters/CodexAdapterV2.test.ts src/orchestration-v2/ProviderContinuationService.test.ts from apps/server: 97/97 passed.
  • Scoped server and provider-core typechecks: no errors. Targeted lint: no errors; two existing unused-variable warnings.
  • Three independent review rounds were completed. Confirmed findings were fixed, including the final late-approval ordering case, with a regression test.
  • Exact final-head real web app verification: external queue reply, resolved command output, native input request/answer/resume, and normal NEXT followed by reload all passed. Native/projection transcript confirms one original native turn and one T3 run for each external message, with no extra turn/start for adoption.

1280×800 CSS, light theme, real web client. Zero-threshold diff and thresholded diff compare richer history rather than an isolated renderer change. Visible differences are the additional turns, request answer, notification rows, timestamps, and workspace sidebar state. No renderer changed. Final stability frames differ only by 16 composer-caret pixels.

Not exercised in the real app: explicit cancellation/late-approval ordering (covered by replay tests), command-approval family (real request proof uses native user input), Electron/native mobile, other providers, relay/tunnel, and the complete size/theme interaction matrix. Earlier 1440/390 light/dark stills are supporting evidence only; matching baselines and final-head interactions at those dimensions were not captured.

Proof audit: scoped A–D sufficient, with limitations. Independent same-state screenshot rebuild was attempted but redirected to pairing; no rebuilt pixel delta is claimed.

…ches T3

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
A turn queued on a loaded native Codex thread (codex queue --thread) had
no T3 run, so its user message, reply, tools and requests were dropped.
The adapter now holds that turn's frames, wakes the thread with a
provider continuation carrying the queued prompt, and the woken run
adopts the native turn and replays the held frames.

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
…vals

Held requests of an externally queued turn now fork like live requests,
so startTurn returns before the user answers. Adoption runs before
/goal and /compact parsing, and a rejected wake, interrupted adoption,
or closed session releases the held frames.

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
…r run settles

Frames that arrive while a held turn drains now queue behind the buffered ones,
the session finalizer enumerates held turns at close, and a woken run that ends
without adopting (cancelled, stopped, failed preparing) releases its turn and
answers held approvals instead of leaving them until the session closes.

🟠 High Adapters/CodexAdapterV2.ts:4438

A child spawned by an external turn can complete before the parent is adopted, leaving the child projected as running with its transcript missing. handleCodexNotification buffers only frames whose turn ID is in heldExternalTurns; the child’s different turn ID falls through to ordinary handlers, which drop its item and completion events before its context exists. Buffer descendant frames too, or register their contexts before dispatching them.

Approvability

Verdict: Needs Human Approval

Macroscope's review found this PR requires human approval — Externally queued Codex turns now wake and attach to T3 runs, including buffered output and approval requests. The open settlement-stream recovery concern needs resolution because a stopped subscription could leave later approvals unanswered until session closure.

Walkthrough

CodexAdapterV2 can offer externally queued turns as continuations, buffer their events and requests, and replay them when a T3 run adopts the turn. ProviderContinuationService can invoke a callback when the run associated with a continuation message reaches a terminal status.

Changes: Codex external-turn adoption

Layer / File(s) Summary
Continuation run-settlement callbacks
packages/provider-core/src/server/ProviderContinuationRequests.ts, apps/server/src/orchestration-v2/ProviderContinuationService.ts, apps/server/src/orchestration-v2/ProviderContinuationService.test.ts
Continuation requests can provide onRunSettled. The service registers callbacks by message ID and invokes them for matching terminal run.updated events. Tests check message and status matching, including callback and stream failures.
External-turn buffering and event routing
apps/server/src/orchestration-v2/Adapters/CodexAdapterV2.ts
CodexAdapterV2 buffers notifications and requests for external turns, tracks spawned-thread ancestry, and routes events through holding and replay wrappers. Requests for turns that are not adopted can fail with a non-adoption error.
Turn adoption and replay validation
apps/server/src/orchestration-v2/Adapters/CodexAdapterV2.ts, apps/server/src/orchestration-v2/Adapters/CodexAdapterV2.test.ts
Turn start and compaction attempt to adopt held turns before starting new Codex work. Replay tests cover queued prompts, approvals, child activity, adopted turns, and turns released after wake rejection or run settlement.

Merge Risk: Moderate · up to 98ab4

The change makes externally queued Codex turns appear in T3. Two edge cases remain: a failed dispatch can drop a Muse turn's buffered output, and a held queue can leave Codex approval requests unanswered until the wake is cancelled or the session closes. Both should be handled before merge.

The description includes the required Problem, Change, Scope and approval, and Verification sections. It explains the bug, implementation, linked issue, focused tests, observed results, limitations, and agent details.

Full details: Linked Issues check

Explanation

Issue #23919 requires externally started codex queue turns on loaded Codex root threads to appear in T3. The turn must include the queued message, agent output, tool activity, and user approvals.

The reviewed implementation holds unmatched root-turn frames, offers the existing continuation wake, adopts the native turn, and replays frames in order. It routes approval requests through deferred responses. It releases buffered requests after rejection or cancellation and rejects later requests until native completion. The added replay coverage tests adoption, child activity, approvals, rejection, cancellation, settlement, and late approvals. The reported targeted test run passed 97/97 tests. These changes satisfy the coding requirements for #23919.

Full details: Out of Scope Changes check

Explanation

The pull request includes changes that do not implement or test external Codex turn adoption for #23919.

The incremental diff adds process-exit retirement and running-agent accounting in CodexAdapterV2.test.ts. It changes Codex collaboration-mode construction, MCP and image output conversion, Unicode output truncation, and active-writer error handling in CodexAdapterV2.ts. It also changes delegated completion from acknowledge-disabled to dispose-disabled in ProviderContinuationService.ts. These changes have no demonstrated connection to recording externally queued turns or delivering their approvals.

Resolution

Remove these unrelated behavior changes from this pull request, or move them to separate pull requests with matching issue scope. Keep only the external-turn buffering, wake, adoption, replay, settlement, and focused regression-test changes.

Make the negative assertion wait for the stream to process the events.

assert.isFalse(yield* Deferred.isDone(settled)) runs right after the two Queue.offer calls. The forked stream fiber has probably not consumed those events yet, so the assertion passes even if a running status fires the callback.

The final Deferred.await(settled) also cannot catch that regression. If running fired the callback, the callback would already have resolved settled.

Make the negative check depend on the stream's progress. One option: register a second request with its own callback and message ID. Offer the two non-matching events for the first message. Then offer a terminal event for the second message, await the second callback, and only then assert that the first callback has not run. As per coding guidelines: "Test meaningful logic or observable behavior."

Keep the settlement stream running after one failure.

The Stream.runForEach callback returns onRunSettled() directly. A defect in one callback fails the whole stream. A failure from streamDomainEvents also fails it. In both cases the catchCause logs once, and the forked fiber then ends.

No later onRunSettled callback runs after that. For Codex, this means a held external turn is only released when the session closes, if its woken run settles without adoption. Until then, its buffered approval requests get no answer.

Contain failures per callback, so one source cannot stop dispatch for all other sources. If an upstream stream failure is recoverable, resubscribe with a bounded retry schedule.

A child spawned by an externally queued Codex turn carries its own thread and
turn ids, so its frames skipped the hold and were dropped before the replayed
spawn could register it. Frames from a thread T3 does not know yet now wait
with the held parent's frames, and fail like the parent's when it is rejected.

A run-settled callback that fails no longer ends the subscription every other
held turn waits on to be released.

AI-assisted; verified with the tests and tools listed above.
Codex sessions are shared by every T3 thread on an instance, so treating any
unregistered native thread as the held turn's child captured other threads'
subagents: their early turn/started was dropped, and their approvals failed,
when the held turn was rejected. Children are now attributed through the
spawn parent Codex reports in thread/started, and only threads whose root
ancestor has a held or rejected external turn are held with it.

Handle buffered wakes when the queue is held.

If a preceding run fails, startNextQueuedRun can hold the queued Codex wake without a terminal update. Its callback remains registered, and buffered requests can wait until the queue resumes, the wake is cancelled, or the session closes.

Ensure held buffered wakes are adopted or rejected without bypassing worktree safety.

Review comment at @apps/server/src/orchestration-v2/ProviderContinuationService.ts around lines 213 - 222:
Update the held-wake handling in startNextQueuedRun so buffered requests are either adopted through the existing worktree-safety checks or rejected and settled; do not dispatch them around those checks. Ensure the onRunSettledByMessage callback registered in the dispatch flow is cleaned up when a held wake is rejected or otherwise cannot proceed, so requests do not remain stranded.

Preserve Muse’s buffered turn on dispatch failure.

If a Muse continuation dispatch fails, clearIfCurrent discards the held turn and its events. Later notifications can also be ignored, so the turn may never appear in the thread. Preserve or recover the Muse wake on failure while keeping the Codex rejection behavior.

Review comment at @apps/server/src/orchestration-v2/ProviderContinuationService.ts around lines 292 - 296:
Update the dispatch-failure handling in ProviderContinuationService around request.clearIfCurrent so a failed Muse continuation preserves or recovers its held wake and events instead of discarding them. Keep the existing Codex rejection behavior unchanged.

The automated pipeline stopped on this pull request and will not merge it:

these checks fail on 98ab424, also when run again: Test Web, and the rework changed nothing:

No code change. The only failing check, Test Web, failed on one test this PR doesn't touch: RightPanelTabs.browser.test.tsx > 'a flick that scrolls the tab strip to its left edge keeps the thread, a swipe from the edge goes back' (expected the call with 'back' that never came). The PR only changes server Codex adapter and continuation files. The same test fails on main just before 42185a6 (#34191), without this PR's changes, and passes at 42185a6. That commit makes the test run as macOS on any CI host and landed on main about four minutes after this CI run finished. A CI rerun or the next merge of main should pass. The earlier review findings (descendant frames arriving before adoption, approvals after a failed callback) are covered by commits from earlier rounds already on the branch (52f370f, 98ab424, 626f19c). Nothing was pushed.

It stays open for a person to finish or close.
