Problem

When a delegated task finishes, the server commits its result and only queues the parent's wake run in a later command. In between, the parent's thread shell reads as completed with no pending work. The web notification gate notifies at once on that state (since https://git.cafe/pingdotgg/t3code/pulls/29146), so with "Notifications with sound" a parent can play "Thread completed" and then go straight back to Working.

Reproduced on main (8ab024f31a): a Claude parent started one async Codex delegate_task and ended its turn. The delegate finished at 19:40:12.364, the parent's wake run was queued at 13.023, and a completion sound played at 13.211. The real completion followed at 15.924. The false alert is a race on when the shell is published: it fired in 1 of 3 live rounds.

Change

The parent's shell keeps a finished delegated task listed as held subagent work until the wake that delivers its result exists. The client then parks the thread at Waiting, as it does while the delegate runs, and nothing reads as settled in the gap. The notification gate is unchanged.

  • pendingDelegatedCompletionWake (NotificationMailbox.ts) is now the single check for a delivery that is claimed but not yet started. The continuation service, the wake offer and every shell producer share it.

  • delegatedTaskItemsAwaitingWake holds two kinds of task:

    • tasks in that claimed delivery;
    • finished sibling tasks still pending behind an outstanding delivery (a sibling finished while the first wake run was active, and its successor wake is not reserved yet).

    A run without a provider thread holds nothing, because no wake can start there. A settled_only task holds nothing while its parent run is live.

  • Both shell paths use it. The memory path calls it from threadShellFromProjection. The SQL path (getThreadShell, shell snapshots, the agent-awareness snapshot, settlement candidates) adds one read, selectShellAwaitingWakeRows. That read is pinned with CROSS JOIN so it starts from the claimed/pending task index instead of walking turn items. may_be_live in the active shell index follows the same rule.

  • Every way out of the hold already writes a parent event: the wake run starts, the task is acknowledged, or the thread is stopped, archived or deleted. The shell is therefore republished when the hold ends. Startup recovery re-offers open deliveries.

  • Held tasks are listed without an owning provider instance. A finished delegate has no provider process, so it does not keep the parent's MCP session live after its run ends (isLiveCallerShell). MCP access matches main; RemoteDelegation.test.ts covers this.

Scope and approval

Fixes #31087

Triaged via the automated issue flow. This is a bug fix and keeps the immediate-notification choice from https://git.cafe/pingdotgg/t3code/pulls/29146.

Verification

Focused tests:

  • DelegatedCompletionDelivery.test.ts:
    • "keeps the parent shell unsettled while its delegated completion wake is pending" fails on main with parent shell reads settled (status completed, no held background work) while its delegated completion wake is still pending and passes here.
    • "keeps the parent shell unsettled while a sibling result waits for its successor wake" covers two delegates. It holds the dispatch lock so the successor reservation cannot run. Without the fix it is red with parent shell reads settled (status completed) before its sibling's successor wake is reserved, and it passes here.
  • ProjectionStore.test.ts, "every shell holds a finished delegated task until its completion wake starts": the thread shell, the shell snapshot, the memory shell, settlement candidates, the agent-awareness snapshot (mobile push) and the shell index agree across these states:
    • claimed with no message: holds
    • provider thread missing: does not hold
    • wake dispatched: does not hold
    • steered into a run that ended unread: holds
    • pending behind a finished wake: holds
    • settled_only with a live parent: does not hold
    • no outstanding delivery: does not hold
  • ProjectionStore, DelegatedCompletionDelivery, ProviderContinuationService, ThreadSettlementService and ThreadStop tests pass: 178/178. The src/mcp and src/peer suites pass: 403/403. Shared orchestrationV2PendingBackgroundWork tests pass: 20/20. vp run check:changed passes.

Query plan for the new read, on a read-only copy of a large real database (232k turn items):

SEARCH s USING INDEX orchestration_v2_projection_subagents_settled_idx (thread_id=?)
SEARCH r USING INDEX sqlite_autoindex_orchestration_v2_projection_runs_1 (run_id=?)
SEARCH p USING COVERING INDEX sqlite_autoindex_orchestration_v2_projection_provider_threads_1 (provider_thread_id=?)
SEARCH item USING INDEX orchestration_v2_projection_turn_items_node_ordinal_idx (node_id=?)

Over all threads it takes about 3.7 ms. Without the join pin, SQLite started from turn_items_thread_run_idx and took about 630 ms. may_be_live added about 2.6 ms.

Runtime transcript from the real app: web dev server with a fresh database, "Notifications with sound", the browser parked on Settings, and completion sounds logged from AudioBufferSourceNode.start. Claude parent, async delegates (Codex, and two Claude delegates in parallel).

Before (main 8ab024f31a):

parent   run 3  completed  11.962
delegate        completed  12.364
parent   run 4  requested  13.023   <- wake
sound                      13.211   <- false "Thread completed"
parent   run 4  completed  15.924
sound                      16.508
(two more delegate rounds: one sound each, after the real completion)

After (fix, 7af21a1140; later commits change the SQL join order and add the sibling case, covered by the tests above):

round 1  delegate done 25.799, wake 26.456, parent done 29.837, sound 30.553
round 2  delegates done 29.555 / 40.662, wakes 30.223 / 41.336, parent done 44.181, sound 45.400
round 3  delegate done 05.275, wake 05.912, parent done 07.655, sound 09.046
round 4  delegate done 26.397, wake 27.647 (1.25 s gap), parent done 32.268, sound 33.015

There were no sounds in any gap. Each sound followed the parent's final completion.

Not checked: the desktop and mobile clients live. Both read the same shell fields: desktop through the web client, and mobile's push through the agent-awareness snapshot, which the ProjectionStore test covers. A Codex parent in this environment had no T3 tools, so only Claude parents were run live.

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

…etion wake

The parent's shell drops the finished delegate from pendingBackgroundTasks as
soon as finalize claims the completion, before the wake run exists, so the
shell reads settled in that window.

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

Finishing a delegated task commits its result, claims the parent's
completion wake, and only then offers the wake, which queues its run in a
later command. In between, the parent's shell read completed with no held
background work, so clients played a false "Thread completed".

Shells now keep the finished task's subagent item as held pending work while
the parent run's claimed delivery has no wake run yet: no message with its id,
or a steer that went unread. That predicate now lives in NotificationMailbox
and is shared by the continuation service, the wake offer, and every shell
producer (projection, thread shell, snapshot, awareness, settlement
candidates). SQL shells find candidates through the indexed claimed
delivery state, so ordinary shell reads pay one index probe. A run without
its provider thread is never offered a wake, so it holds nothing. The active
shell index counts claimed tasks as possibly live.

Fixes #31087

AI-assisted; verified with the tests and tools listed above.
Pin the join order so the awaiting-wake shell read starts from the
claimed-task index instead of walking every turn item of each thread.
A sibling task that finished while its parent's wake run was active stays
in the `pending` delivery state until the terminal-run listener reserves it
a successor wake. In the gap after that wake run ended, the parent shell
read completed with no pending background work, so the web gate could fire
a false "Thread completed".

Finished app-owned tasks left pending behind an outstanding delivery now
hold like claimed ones, in the memory and SQL shell paths alike. They follow
the successor reservation's rule: a live parent's blocking wait takes
settled_only results, so those do not hold. The four-producer ProjectionStore
test now also checks the agent awareness snapshot that feeds mobile pushes.

Merge Risk: Low · up to 1ece4

The change keeps a parent thread unsettled until the delegated result's wake starts. Shell reads may become slower in threads with many historical delegated tasks, so consider adding an index. This is not likely to break the feature.

Explanation

Issue [#31087] requires an accurate completion alert when a delegated task finishes before the parent wake starts. The PR holds qualifying delegated task items as pending background work until the completion wake starts. The summary reports shared wake checks across continuation and shell paths, plus regression tests for claimed wakes and sibling successor wakes. The current PR description reports the focused suites and changed-code check passing. The incremental changes inspected do not remove this behavior.

Full details: Out of Scope Changes check

Explanation

The PR includes changes with no demonstrated connection to issue [#31087]. The incremental ProjectionStore.ts diff adds thread-link metadata and title APIs, recovery project filters, deferred history-window logic, and generic background-wake classification. The test diff adds coverage for pending-request cards and these APIs. These changes address separate thread-link, history-window, and generic wake behavior, not the delegated-completion alert race.

Resolution

Remove the unrelated thread-link/title APIs, recovery filtering, deferred history-window changes, and generic background-wake behavior and their tests from this PR, or link an applicable active issue and keep that work in a separate scoped change.

apps/server/src/orchestration-v2/ProjectionStore.test.ts: 1

1756-1757: Trivial · Functional Correctness · Quick win

The live-parent assertion does not test the settled_only branch.

After applyRun("parent-live", ...), a run has status running. Every shell producer then returns an empty list for a different reason:

  • derivePendingBackgroundWork returns [] when hasActiveRun is true.
  • getSettlementCandidates excludes threads with an active run, so [0] is undefined.

The assertion at Line 1757 therefore passes even if the (!runIsLive || task.completionWake === "always") condition in delegatedTaskItemsAwaitingWake is removed. The comment on Line 1750 claims coverage that the test does not provide.

Test this branch directly with delegatedTaskItemsAwaitingWake. Build a projection with a live parent run, an open delivery and a pending settled_only task. Assert that the result is empty. Add the matching always case, which must return the item. Put the cases in the existing DelegatedCompletionDelivery or mailbox test table, so the test stays at the lowest layer.

As per path instructions: "Hold changed tests to the rules in docs/internals/testing.md." That document says to "test at the lowest layer that catches the regression".

Add an index for tasks awaiting a wake.

The existing index puts status before completion_delivery_state, but this query does not filter status. Shell reads can therefore scan historical tasks in each selected thread, even when none await a wake. The may_be_live subquery has the same predicate.

Add an index on (thread_id, completion_delivery_state), or a partial index on thread_id for the claimed and pending states.

Review comment at @apps/server/src/orchestration-v2/ProjectionStore.ts around lines 6626 - 6656:
Add an index on thread_id and completion_delivery_state, or a partial index on thread_id restricted to the claimed and pending states, so the filters in selectShellAwaitingWakeRows and the may_be_live subquery can avoid scanning historical tasks. Preserve the existing indexes.

Evidence

Environment for all captures: Linux web dev app, separate worktrees and fresh databases, identical synthetic delegation fixture, 1280×800 CSS viewport, dark theme. Videos include an evidence caption below the original viewport and contain no audio.

Steps on both revisions: enable Sound only and In-app notifications; remain in Settings while a parent launches an asynchronous delegate, ends its turn, resumes on delivery, and processes the result. Repeat with two delegates finishing 12 and 22 seconds after launch, overlapping the parent's 15-second processing turn. System notification permission was denied, so Notifications with sound could not be exercised.

Before After

One-delegate recording: premature completion toast, then another after final completion. Same one-delegate recording: only the final completion toast.
Two-delegate recording: one final alert in this attempt. Same two-delegate recording: one final alert.

The live client trace confirms the one-delegate race: base played the completion sound and displayed its toast at observer +13.119 seconds, then resumed the parent at +13.158 seconds. Head produced no handoff alert and played its only completion sound after the resumed parent completed. Observer clocks are independent of video timestamps.

Drivers, seed, traces, and detailed reproduction notes. Individual scripts: fixture provider, seed, scenario driver, client observer.

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

Not shown:

  • Operating-system notifications and the exact Notifications with sound setting: the preview browser denied notification permission; both sides used Sound only plus visible in-app notifications.
  • Audible sound recording: videos are silent; sound evidence records actual AudioBufferSourceNode.start calls in the real client.
  • The intermittent two-delegate premature alert was not reproduced on base in the recorded attempt; both revisions emitted one final alert.
  • The Waiting sidebar label during the brief handoff is obscured by Settings; client traces show pending delegated work and parent run transitions.
  • Desktop and mobile surfaces were not exercised.
  • Remote origin/main freshness could not be confirmed because fetch returned HTTP 503 twice; the reported base is the merge-base computed from the available local origin/main.
