fix(server): a follow-up to a delegated child waits for its awaited background work - #36411
The first review round had no items. CodeRabbit's review of ef86c2e raised two Major findings. (1) Fixed: cancelDelegatedTask decided whether a follow-up was unsettled from its run's terminal status alone. With this PR a follow-up can stay open after its run ends while the child awaits background work, so Stop committed without cancelledRunId, and clearing the roster then finalized the interim reply as 'completed'. unsettled for follow-ups now also counts delegatedTaskAwaitsWork(delegatedTaskRuns(child, taskId), child), as the original task's progressAfterTurn check does. The held-follow-up test is now it.effect.each(['woken','cancelled']); the cancelled case asserts cancelledRunId is the follow-up's run and the status is 'interrupted', and it fails without the change. (2) Declined, Muse wake ordering: the Muse adapter clears the background roster when the item ends and offers the wake later, at turn/started, so the follow-up can finalize with the interim reply before the wake attaches. The child's original delegated task has the same gap today: it also finalizes at roster clear, before the wake. So this ordering predates the fix, and closing it needs a new reservation mechanism in the Muse adapter. Macroscope's 'Needs Human Approval' verdict cites this declined finding. CodeRabbit's later review of 748fa7e left one Trivial nitpick (assert the cancelled state before the roster clears), below the high bar, so it was left. All 35 checks pass on 748fa7e.
Commit bc7fe11 (origin/main). Started T3CODE_DEV_SEED=0 vp run dev on a fresh database, added a scratch git project with t3 project add, and started a Claude parent thread (claude-sonnet-5-5) with t3 thread start. Its prompt said: delegate_task (mode wait) a claude-haiku-5-5 child that replies READY, then t3_thread_send the child the reporter's follow-up (start sleep 90; echo CHECK-OK with run_in_background, call t3_background_wait, reply INTERIM and end the turn, reply FINAL <output> when woken), then echo each delegated result it receives. Read the dev database read-only. 21:41:57: the original task completed with READY. 21:42:07: the child replied INTERIM. The follow-up task (thread-send) was marked completed with result INTERIM, and the parent was woken and replied 'GOT: INTERIM'. At the same time the child's provider thread had pendingBackgroundTasks=[{taskId:'bn73vi3w6', kind:'command', awaited:true}]. 21:43:34: the command finished and woke the child (child run 3). 21:43:37: the child replied 'FINAL CHECK-OK', which created a second app-owned task (provider-continuation) on the parent, and the parent was woken again ('GOT: FINAL CHECK-OK'). Also added a unit test in DelegatedCompletionDelivery.test.ts that fails on main with expected 'INTERIM' to equal null.
Evidence
Delegate a Claude Haiku child that replies READY, then send the identical follow-up: run sleep 90; echo CHECK-OK in the background, await it with t3_background_wait, reply INTERIM and end the turn, then reply FINAL CHECK-OK when woken. The Sonnet parent echoes every result.
Real web client, Chromium, 1440×1000, light theme; separate fresh databases and synthetic git project. Base delivered INTERIM while background work remained awaited, then delivered the final reply through a separate task. Head retained the follow-up until completion and delivered only FINAL CHECK-OK.
Recordings crop to the conversation, omit the same 75-second idle interval, and hold the final screenshot for five seconds. Final screenshots were inspected and matched captures taken 500 ms apart.
vp test run src/orchestration-v2/DelegatedCompletionDelivery.test.ts: 62/62 pass (the new cancelled case fails with the Orchestrator change stashed: cancelledRunId undefined). vp run check:changed: format, lint, knip, typecheck (3 packages) and tests for 8 changed files all pass. PR CI: all 35 checks pass on 748fa7e.
Not in this change
When a second follow-up B starts while follow-up A is held on background work, A stays open until that work settles and then closes with its own last reply; the wake joins B, the latest open follow-up. Not changed.
Background work is not tied to the run that started it, so any awaited background work on the child holds every open follow-up, as it already holds the original task.
Muse ordering (CodeRabbit Major, declined): the adapter clears the background roster before it offers the wake at turn/started, so a follow-up, like the original delegated task today, can finalize with the interim reply before the wake attaches. Closing it needs a reservation mechanism in the Muse adapter.
CodeRabbit Trivial nitpick: assert the cancelled follow-up state before the background roster clears in the test.

A follow-up task closed as soon as its run ended, with the child's interim
reply, even while the child still awaited a background command. When the
command finished, its wake opened a second task and woke the parent again.
A follow-up now also waits on the child's awaited background work, as the
original delegated task does, and a provider wake joins the latest

Macroscope's review found this PR requires human approval — Delegated follow-ups now wait for background work and reuse an open follow-up for notification wakes. An unresolved review concern identifies a settlement/wake race that could deliver an interim result and duplicate parent notifications; the ordering guarantee needs human resolution.

Notification-triggered runs can reuse an active follow-up task for the same app-owned child. Finalization, cancellation, and pending-result checks use the expanded completion predicate. The MCP work-state check uses it to report waiting_for_children or result_available.
Tests check that a pending background command keeps the follow-up unsettled, that cancellation interrupts it, and that command completion leads to a continuation run that settles the same task with the final reply.

Full details: Title check
Explanation
The title states the main behavior change: a follow-up to a delegated child now waits for the child's awaited background work. It matches the raw summary (delegatedTaskAwaitsWork holds the task while awaited background work is pending) and the PR objectives. It follows the conventional commit form and is specific, although it omits the wake-run attribution change.
Full details: Linked Issues check
Explanation
Issue #36403 has one direct coding objective. A follow-up to a delegated child must stay open while the child's awaited t3_background_wait work is pending, must end with the final reply, and must wake the parent once.
Hold on awaited work: The whole-PR diff (merge base bc7fe11 to head 748fa7e) replaces delegatedTaskAwaitsSubagents with delegatedTaskAwaitsWork in RestartBackgroundNote.ts. The new helper returns true when any child provider thread has pendingBackgroundTasks that satisfy backgroundWorkHoldsCompletion. Orchestrator.ts uses it in finalizeAppOwnedSubagentTask, in the delegated task result-pending check, and in the follow-up path at the reviewed head. OrchestratorMcpService.ts uses it for the MCP task status. A cancelled follow-up passes providerThreads: [] in finalization, so it does not wait on work its cancel stops.
Attribution of the wake run: In recordSubagentFollowup, a notification-driven run is tagged with the child's latest open follow-up. An open follow-up has origin app_owned, the same child thread, no cancelledRunId, and result null. The wake therefore does not create a second task or a second parent wake. User and agent sends still create their own task.
Tests: The PR reports DelegatedCompletionDelivery.test.ts at 61/61, including a repro test that checks the wake run carries the follow-up id and that the follow-up completes with FINAL CHECK-OK. The PR reports that this assertion fails with the attribution change disabled. I did not run the tests. I relied on the reported results and the diff.
Uncertainty that does not change the verdict: The cancelled exclusion applies in finalizeAppOwnedSubagentTask. The delegatedTaskResultPending check receives the full childControls for a cancelled follow-up. The issue states no cancelled-task requirement, so this does not affect the objective.
Full details: Out of Scope Changes check
Explanation
All changed code maps to issue #36403 or to its supporting tests and helpers. (1) RestartBackgroundNote.ts: rename of the helper to delegatedTaskAwaitsWork and addition of the provider-thread check. (2) Orchestrator.ts: use of the helper in finalization, result-pending, and follow-up completion checks; cancelled-task exclusion in finalization; run attribution to the open follow-up in recordSubagentFollowup. (3) OrchestratorMcpService.ts: use of the helper for the MCP task status. (4) DelegatedCompletionDelivery.test.ts: regression tests for the held follow-up and the wake attribution. The diff shows no unrelated refactoring. The PR description lists two known limits: a second follow-up started while the first is held, and background work not tied to its starting run. These are documented as unchanged behavior, not added scope.
Full details: Description check
Explanation
The description is thorough. It explains the problem (a follow-up to a delegated child completes with an interim reply while the child still awaits background work), the change (holding the follow-up via delegatedTaskAwaitsWork and attributing the wake run to the held follow-up), and the scope (links the issue, #36403). Verification is detailed: a focused test file run with 62/62 passing, a stash-based check showing the new cancelled case fails without the change, the check:changed run, and before/after screenshots and recordings from a reproduction on main. It also states the known gaps (the Muse wake ordering finding declined, and the second-follow-up case), so reviewers can see what is not covered. It does not follow the template's headings exactly: it opens with a review-round narrative instead of a conventional commit title and a Problem section. The Change section is folded into the narrative and the Scope section is only a single issue link, which is acceptable for a bug fix with a linked issue. The agent attribution is present. Overall the required information is present, so the check passes.

Mark cancellation when a terminal follow-up still awaits background work.
A follow-up can now have a completed run while its task remains open with result === null. In that state, this expression sets unsettled to false. cancelDelegatedTask therefore commits Stop without cancelledRunId.
When Stop clears the background roster, finalization treats the run as successfully completed and publishes its interim reply. The cancellation exception at Line 14156 cannot apply because the marker was never written. Include awaited work when deciding whether cancellation must mark the follow-up.

A Muse wake can arrive after its follow-up is already finalized.
When Muse clears a child's background roster, the settlement listener finalizes the open follow-up with the interim run result. The wake for that background work is offered later, at turn/started. By then recordSubagentFollowup cannot attach the wake, because the follow-up already has a result. It creates a second delegated task instead. The parent then receives the interim reply and a second wake for the final reply.
Nothing reserves the follow-up between roster settlement and the wake. The offer is only queued, and the parent lock orders the two steps without fixing which runs first.

A follow-up can now stay open after its run ends while the child awaits
background work. Stop decided whether to mark the task cancelled from the
run status alone, so it left the marker off, and clearing the background
roster then published the interim reply as a completed result.
Co-Authored-By: Claude Opus 5.5 <[email protected]>
Assert the cancelled follow-up while the awaited command is still on the roster.
In the cancelled branch, the cancelledRunId and interrupted checks run only after eventSink.write clears pendingBackgroundTasks and recoverDelegatedTasks completes. If finalization waited for the awaited command, the follow-up would still reach the same state once the roster clears, so the test would still pass. This leaves the stated rule that cancellation does not wait for background work untested.
Move the cancelled-state check so it runs before the roster write. If the cancel path finalizes only after a recovery pass, run recoverDelegatedTasks before the roster write and assert there. Keep the post-settlement assertions if they also check that the final result is preserved.

The fork pulled upstream pingdotgg#21877 (later pingdotgg#33539) so a
follow-up sent to a delegated task waits for nested work its run started.
Upstream fixed the same behavior in pingdotgg#34958 and pingdotgg#36411, so the fork drops
its source change and keeps the tests: the pingdotgg#16603 follow-up reproduction
from c8ecd1f is no longer quarantined, and the MCP task_status cases
still pass on upstream's code.
The "nested" and "nested-active" rows of "delivers a %s follow-up" are
gone. They asserted the fork's wake routing (the wake run is tagged with
the follow-up's task id), while upstream counts untagged wake runs as
part of the follow-up instead.

The first review round had no items. CodeRabbit's review of ef86c2e raised two Major findings. (1) Fixed: cancelDelegatedTask decided whether a follow-up was unsettled from its run's terminal status alone. With this PR a follow-up can stay open after its run ends while the child awaits background work, so Stop committed without cancelledRunId, and clearing the roster then finalized the interim reply as 'completed'.
unsettledfor follow-ups now also counts delegatedTaskAwaitsWork(delegatedTaskRuns(child, taskId), child), as the original task's progressAfterTurn check does. The held-follow-up test is now it.effect.each(['woken','cancelled']); the cancelled case asserts cancelledRunId is the follow-up's run and the status is 'interrupted', and it fails without the change. (2) Declined, Muse wake ordering: the Muse adapter clears the background roster when the item ends and offers the wake later, at turn/started, so the follow-up can finalize with the interim reply before the wake attaches. The child's original delegated task has the same gap today: it also finalizes at roster clear, before the wake. So this ordering predates the fix, and closing it needs a new reservation mechanism in the Muse adapter. Macroscope's 'Needs Human Approval' verdict cites this declined finding. CodeRabbit's later review of 748fa7e left one Trivial nitpick (assert the cancelled state before the roster clears), below the high bar, so it was left. All 35 checks pass on 748fa7e.Fixes #36403
Reproduction on main
Commit bc7fe11 (origin/main). Started
T3CODE_DEV_SEED=0 vp run devon a fresh database, added a scratch git project witht3 project add, and started a Claude parent thread (claude-sonnet-5-5) witht3 thread start. Its prompt said: delegate_task (mode wait) a claude-haiku-5-5 child that replies READY, then t3_thread_send the child the reporter's follow-up (startsleep 90; echo CHECK-OKwith run_in_background, call t3_background_wait, reply INTERIM and end the turn, replyFINAL <output>when woken), then echo each delegated result it receives. Read the dev database read-only. 21:41:57: the original task completed with READY. 21:42:07: the child replied INTERIM. The follow-up task (thread-send) was marked completed with result INTERIM, and the parent was woken and replied 'GOT: INTERIM'. At the same time the child's provider thread had pendingBackgroundTasks=[{taskId:'bn73vi3w6', kind:'command', awaited:true}]. 21:43:34: the command finished and woke the child (child run 3). 21:43:37: the child replied 'FINAL CHECK-OK', which created a second app-owned task (provider-continuation) on the parent, and the parent was woken again ('GOT: FINAL CHECK-OK'). Also added a unit test in DelegatedCompletionDelivery.test.ts that fails on main withexpected 'INTERIM' to equal null.Evidence
Delegate a Claude Haiku child that replies READY, then send the identical follow-up: run
sleep 90; echo CHECK-OKin the background, await it witht3_background_wait, reply INTERIM and end the turn, then reply FINAL CHECK-OK when woken. The Sonnet parent echoes every result.Real web client, Chromium, 1440×1000, light theme; separate fresh databases and synthetic git project. Base delivered INTERIM while background work remained awaited, then delivered the final reply through a separate task. Head retained the follow-up until completion and delivered only FINAL CHECK-OK.
Recordings crop to the conversation, omit the same 75-second idle interval, and hold the final screenshot for five seconds. Final screenshots were inspected and matched captures taken 500 ms apart.

Tests
vp test run src/orchestration-v2/DelegatedCompletionDelivery.test.ts: 62/62 pass (the new cancelled case fails with the Orchestrator change stashed: cancelledRunId undefined). vp run check:changed: format, lint, knip, typecheck (3 packages) and tests for 8 changed files all pass. PR CI: all 35 checks pass on 748fa7e.
