Problem

A delegated child's "asked a question" notification is queued on its parent with queue_after_active. Nothing ties that queued run to the question's lifetime. When the child finishes, or its question is answered or closed, before the parent's turn ends, the wake still starts after the parent's final turn. Its answer to the stale question then becomes the parent's latest result, which is what delegate_task and task_status report upward. Reproduced on main with the orchestrator tests below: the stale wake stays queued after the task settles, and starts (starting) when the settle event was missed.

Change

A question wake now lives only as long as its question:

• DelegatedTaskQuestionReactor cancels a parent's queued wakes when the child's question is answered or closed, and when the app-owned task settles (completed, failed, cancelled, interrupted). A failed cancel is logged and the others still run.
• Orchestrator.startNextQueuedRun sweeps queued question wakes before choosing the next run. It cancels any whose task is gone or settled, or whose request is no longer pending. This also covers events missed across a restart and wakes queued by an older server. A failed child-thread read is logged and the wake is kept, so it can never fail the parent's unrelated next queued run.
• dispatchMessage accepts a stale wake as a no-op (the existing thread.metadata-updated pattern) instead of starting a run.

Result selection is unchanged: a question wake that is still valid when it starts is real work and is treated like any other turn.

Scope and approval

Fixes #25639

Triaged via the automated issue flow; GitCafe issue https://git.cafe/pingdotgg/t3code/issues/25637.

Verification

• Orchestrator.control-reads.test.ts, the new drops a stale question wake cases (live settle event, and missed event plus queue resume). Each also checks that a live follow-up question on the same child still wakes the parent, and that a stale wake dispatched directly is accepted without starting a run. On main both cases fail: expected 'queued' to equal 'cancelled' and expected 'starting' to equal 'cancelled'.
• On e041743849: vp run check:changed passed (format, lint, knip, typecheck of 3 packages, tests). Orchestrator.control-reads.test.ts: 14 passed.

✓ wakes the parent once when its delegated task asks a question
✓ drops a stale question wake (missed terminal event: false)
✓ drops a stale question wake (missed terminal event: true)
Tests  14 passed (14)

• Related suites (DelegatedCompletionDelivery, SubagentProjection, OrchestratorMcpService, SteeringCompletion.integration): 110 passed on the reviewed head.
• Server-only change with no render path, so there are no captures. Not checked: a live multi-level provider run.

Walkthrough

The reactor cancels queued delegated-question wakes when a child task becomes terminal or its request is no longer pending. The orchestrator detects stale wakes before queue selection and message dispatch. Tests cover normal and missed terminal-event paths.

Changes: Delegated question wake lifecycle

Layer / File(s)	Summary
Cancel wakes from task and request updates apps/server/src/orchestration-v2/DelegatedTaskQuestionReactor.ts	The reactor finds queued parent runs for delegated-question messages and dispatches cancellation when an app-owned subagent becomes terminal or a request is no longer pending. Cancellation failures are logged.
Prune and block stale wakes apps/server/src/orchestration-v2/Orchestrator.ts, apps/server/src/orchestration-v2/Orchestrator.control-reads.test.ts	Before selecting a queued run, the orchestrator cancels stale wakes and reloads the queue projection. It skips stale incoming messages. Tests cover missed and normal terminal-event paths, including a new follow-up question wake.

Approvability

Verdict: Needs Human Approval

Macroscope's review found this PR requires human approval — This change removes obsolete delegated-task question wakes before they start parent turns. An unresolved review concern identifies a completion-before-finalization window that could still launch a stale turn and replace the parent's reported result; that ordering needs resolution.

No code changes detected at 1dc5d47. Prior analysis still applies.

Continue cancellation after a per-request failure.

When a queued-run.cancel dispatch loses its race with queue start, the dispatch rejects and the loop stops. The remaining request IDs are not cancelled and can remain queued until a later queue-start cleanup. Handle each dispatch failure locally, log it, and continue.

🚀 Performance & Scalability | 🟡 Minor | ⚡ Quick win

Return only when no user_input request exists.

Do not return merely because no request is pending. If a resolution event was missed, a closed request can still have a queued wake. startNextQueuedRun provides a fallback, but it returns while a blocking run exists before it calls cancelStaleQuestionWakes. The terminal event must still cancel that wake immediately.

This still avoids the runs and nodes scans when the child has no user-input requests.

Limit the stale-wake guard to question-wake messages.

isStaleQuestionWake treats every delegated_task notification with outcome updated as stale unless a pending user_input request matches its message ID. It does not first check that the message ID is a question wake. If a notification with this shape is dispatched as a message, dispatchMessage and cancelStaleQuestionWakes drop it. Add a prefix check before the source test:

Suggested fix

+    if (!messageId.startsWith("message:delegated-task-question:")) return false;
     if (notification?.source.kind !== "delegated_task" || notification.outcome !== "updated")
       return false;

The question-wake message ID format is also built in DelegatedTaskQuestionReactor.ts (wakeParent and cancelQueuedWakes) and compared in this guard. Export one helper for the format and use it in all three places, so the copies cannot drift apart.

@coderabbitai Outside-diff item (DelegatedTaskQuestionReactor.ts:146-166): fixed in e041743. The settled-task branch now reads only runtimeRequests first and returns when the child has no user_input request. Otherwise it reads runs and nodes and cancels as before.

Nitpick (isStaleQuestionWake prefix check): not changing. DelegatedTaskQuestionReactor.wakeParent is the only producer of a delegated_task notification with outcome updated; completion notices use other outcomes and are not stored as messages with that source. A prefix guard and a shared id helper would add code without changing behaviour.

Dismissing prior approval to re-evaluate e041743

@juliusmarminge Confirmed in the current source: the settled-task branch reads runtimeRequests first and returns when there is no user_input request. It reads runs and nodes only when needed. That addresses the outside-diff concern.

I withdraw the prefix-check nitpick. wakeParent produces the delegated_task notification with outcome updated, which isStaleQuestionWake already checks. The extra prefix guard and shared ID helper are unnecessary here.

## A note from Theo

I like ambitious ideas, simple systems, and software that feels obvious. Do not preserve complexity just because it already exists. Do not introduce machinery because it looks architecturally impressive. Understand the real constraint, then fight for the smallest model that makes the correct behavior unsurprising.

Check child settlement before promoting a question wake.

A message-capability question can remain pending after the child finishes. If the parent queue resumes before task finalization, isStaleQuestionWake accepts the wake and can start a parent turn that later cancellation cannot remove.

Check the child’s settled state before promotion, while preserving wakes for tasks with active work. Add a test that resumes the queue after child completion but before parent-task finalization.

Review comment at @apps/server/src/orchestration-v2/Orchestrator.ts at line 1922:
Update isStaleQuestionWake handling for the delegated-task question message so it checks whether the child has settled before promoting the wake, while preserving wakes for children with active work. Use the existing child-state signal and add a test that resumes the queue after child completion but before parent-task finalization.

After applying the fix, consider running `coderabbit review --agent` for local review. Visit https://docs.coderabbit.ai/cli?utm_source=ghpr

Evidence

Create a synthetic project and launch a parent without active steering. Delegate a child that emits a nonblocking question and completes without an answer. Keep the parent active, confirm the child completed using task_status, inspect t3_queue, then let the parent write FINAL OUTCOME and finish.

Both sides: real isolated servers, fresh synthetic data, Chromium on Linux, 1280×800, light theme. Provider protocols were scripted through the real adapters. Recordings are normal-speed settlement excerpts with startup removed. Both stills passed the identical-screenshots check at least 500 ms apart.

Base: completed child, one queued question, then an obsolete parent turn. Head: completed child, empty queue, final outcome preserved.

Scenario · Parent replay · Child replay · Setup driver · Runtime transcript · Execution transcript

AI-assisted; verified with the tests and tools listed above.

Not shown:

• Nested grandparent task_status result replacement was not exercised; evidence covers the direct parent's obsolete extra turn and final transcript.
• Question resolution without child completion, delayed delivery, restart recovery, and valid-question wake controls were not separately exercised; this reproduction covers completion with an unanswered asynchronous question.
• Live-provider reasoning and desktop/mobile clients were not exercised; provider traffic was scripted through the real server adapters.

Evidence

Delegate supervisor → parent → child. Let the child ask a nonblocking question and finish without an answer while the parent continues working. Finish the parent, then inspect its outcome and the supervisor's actual task_status result. Both sides use fresh synthetic data, Chromium 1280×800, light theme, and identical replay drivers.
