fix(web): don't send completion notifications for snoozed threads - #27458
When a run finishes in a snoozed thread, the web client still shows a "Thread completed" notification, even though the thread stays snoozed and hidden until its wake time. The notification gate looks only at run settlement, archive state and stop requests. It doesn't check snooze.
Repro: snooze a thread while it has an active run → let the run complete → a completion notification fires, and the thread is still snoozed.
Expected: no completion notification while the thread is snoozed. Notifications that need the user (approval/input, failures) should still come through.
Change
ThreadNotificationObservation gets a snoozed flag. It comes from a new helper, isSnoozedForNotification, which reuses effectiveSnoozed from client-runtime/state/thread-settled and checks it at the current time and, for a completion at or after snoozedAt, at completedAt. A completion that landed during the snooze stays suppressed even when its update is processed after the wake, for example in a throttled background tab. An early wake for attention still turns suppression off.
createThreadNotificationGate handles snoozed the same way as quiet: it cancels any pending completion and marks the newest settled completion as handled. A completion from before or during the snooze therefore doesn't notify after the wake, including after a runtime blip.
Attention notifications (approval/input/limited) still go through the existing path and keep firing for snoozed threads.
Scope and approval
This is a small, focused fix with no prior issue. Snooze is meant to hide a thread until a given time, so a completion notification during the snooze goes against what the feature is for. The change touches only the client-side notification gate and adds one boolean input. It doesn't change snooze, run state or server behavior.
Verification
Unit tests in ThreadNotificationCoordinator.logic.test.ts:
no completion notification while snoozed, and none after the thread becomes unsnoozed for the same completion;
attention (approval) still notifies while snoozed;
a completion is dropped when the thread is snoozed during a runtime blip, both while it is still pending and after an earlier working observation cancelled it. Both cases were raised by CodeRabbit and both tests fail without the fix;
isSnoozedForNotification: snoozed before the wake time, a completion from the snooze processed after the wake, a completion from before the snooze processed after the wake, a completion after the wake, and an early wake for attention.
vitest run src/components/ThreadNotificationCoordinator.logic.test.ts locally: 21/21 passed. tsc --noEmit for apps/web is clean. The pre-commit fmt/lint hooks passed.
Found the bug on a real thread: status=completed, snoozed=true, and a "Thread completed" notification was delivered.
Not done: I didn't check the change manually in the running app.
Initial change by Codex (GPT) via T3 Code; review follow-up fix and PR description by Claude Opus 5.5 via Claude Code.
Macroscope's review found this PR approvable — Completion alerts are suppressed for snoozed threads without replaying the same completion after wake-up; attention alerts remain unchanged. The change is limited to client-side notification behavior and leaves default settings and stored thread state untouched.

Walkthrough
The coordinator computes each thread’s effective snooze state and passes it to the notification gate. The gate suppresses completion notifications when the thread is snoozed, including completions that occurred during snooze but are processed after wake. Attention notifications still fire during snooze.

Summary
Derive and pass snooze state apps/web/src/components/ThreadNotificationCoordinator.logic.ts, apps/web/src/components/ThreadNotificationCoordinator.tsx
The observation contract adds a snoozed flag. The coordinator computes it from the thread’s snooze state, completion time, and current time, then passes it to the notification gate.
When an observation is snoozed, the gate marks the completion as handled. Tests cover completion timing around snooze and wake, early wake associated with pending approvals, and attention notifications during snooze.
pingdotgg/t3code#26886: This change updates the same notification gate to suppress completion notifications based on thread state.
pingdotgg/t3code#29212: This change suppresses routine completion notifications while a thread is snoozed; the issue concerns project-level snooze.

- Line 44: When `options.snoozed` cancels a pending completion in
`ThreadNotificationCoordinator` logic, record the pending completion timestamp
as handled before calling `cancel(key)`, so settling again with that same

`ThreadNotificationCoordinator` to classify a completion using its completion
time relative to the snooze interval, rather than the update arrival time.
Preserve early attention wakes so they continue to surface before the snooze

A completion still waiting out its grace was cancelled on snooze but not

…te updates
- Snoozing now marks the newest settled completion handled, not only one
still pending, so a completion cancelled by an earlier working blip
cannot notify after wake.
- Snooze is also evaluated at the completion time, so a completion that
landed during the snooze but was processed after the wake (e.g. in a
throttled background tab) stays suppressed.

Re-check snooze state before firing a pending completion.

Re-check snooze state before firing a pending completion.
A settled observation schedules a timer, but the timer callback calls notify(key, "completion") without checking snooze state. Snooze cancels that timer only when a snoozed shell observation reaches observe. If shell delivery is delayed until after the timer fires, the callback can call present and create a desktop notification for the snoozed thread.
Add an independent callback-time snooze check using the current snooze state before calling notify.

Update the pending completion timer callback in the observation handling flow to
check the current snooze state for the thread before calling notify. Keep the
callback-time check independent of observe-based cancellation so delayed shell
delivery cannot trigger a notification for a snoozed thread.

@coderabbitai Re: "Re-check snooze state before firing a pending completion" (logic.ts L76-87). I'm not changing this in this PR. The timer only fires for a completion the client saw while the thread was not snoozed. The race needs the user to snooze within the ~2 s grace window, and the snoozed shell update has to arrive after the window closes. Notifying a completion that happened before the snooze is reasonable in that case. Closing the gap would mean the gate pulls live thread state through an injected callback at fire time, which widens the gate API beyond this fix. Snoozes applied during the grace window are already handled when the snoozed observation reaches observe (it cancels the timer and marks the completion handled).
For best results, initiate chat on the files or code changes.

@maximkes Agreed. I checked observe: a snoozed observation cancels the pending timer and marks the newest settled completion as handled.
The remaining race requires the snoozed update to arrive after the timer fires. Your explanation makes the intended boundary clear: a completion observed before snoozing can still notify in that case.
I withdraw the request for a fire-time state recheck. No gate API expansion is needed for this PR.

## 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.
Merged current main into the contributor head again without rebasing (d8f887ef1c). Main's notification gate now keys attention by request id (requestId on the observation plus an attended set). The conflicts were resolved by keeping that and this PR's snoozed suppression and completion-time classification. The test fixtures were updated to carry both requestId and snoozed.
Blacksmith: vp run check:changed against main passed (format, lint, knip, typecheck, 13 notification logic tests, 9 notification badge browser tests, React compiler). The CodeRabbit findings were already fixed by the contributor in 5139014, d59980b and 18fe5c4.
Unverified: a manual snooze check in a live client. No UI evidence is claimed because the change only gates notifications.
Resolve against main's background-wake grace: a snoozed thread also
drops a pending wake completion. Keep snooze as a gate option only and
fold the snooze-timing tests into one table.

All captures: real web client, Linux Chromium 156.0.8078.4, 1280×800, light theme, focused visible tab, fresh synthetic project and threads on each commit, Replay (dev). Same first-run interaction and pointer position on both sides.
Enable Settings → General → In-app notifications. Keep Other thread focused and visible. Start a first 350-line text-only replay run; while Working, choose Snooze → In 1 hour. Move the pointer to (900,600) on both sides. Wait for completion, capture the notification surface, then open the finished transcript showing line 350, the completion marker, and 60m remaining. Separately snooze approval, question, and failure runs before their attention events arrive. For delayed completion, hold application WebSocket delivery after snoozing, await server completion, advance the client clock 3,601,000 ms and fire its existing wake timers, then release queued messages.
Delayed delivery uses a simulated clock advance, not a literal one-hour wait. Reopening its transcript resets the browser clock, so that screenshot shows the original 60m snooze remainder. Videos omit authentication and initial setup screens; reproduction interactions and waiting retain their original speed.
The five-second background-wake completion grace timer and completion predating a later snooze were not separately captured; these runs exercise direct completion during snooze, including delivery after wake.
System notification and sound channels were not captured; this proof covers web in-app alerts.
The relay published a snoozed thread's completion, so iOS and Android
still alerted. It now withholds a completion that landed during the
snooze, checked at completion time like the web gate, so a completion
processed after the wake stays silent too.

Real web app in Chromium on Linux, light theme, 1280×800 CSS pixels (captures 2560×1600), isolated synthetic data and Replay (dev) on both commits. In-app notifications enabled; the tab remained focused and visible.
Steps on both sides: start the first long text-only reply (350 numbered lines), snooze its working thread for one hour, open Other thread, park the pointer in the composer, wait for completion, then open the finished conversation. Both recordings show the completed response and the thread still snoozed with 59m remaining.
Delayed processing: repeat with a fresh thread, then advance the browser's Date constructor and Date.now by 3,601 seconds before completion arrives; server timestamps stay unchanged. The completion timestamp falls inside the snooze, while the client processes it after wake. Base alerts; head stays silent. The recordings show the transition to Woke; the head recording also opens the finished response. The base video ends before unrelated subsequent setup.
Attention alerts: start each fresh replay thread, snooze it while working, return to Other thread with the pointer in the composer, then let the recorded attention event arrive. All three wake and alert on both commits.
Relay/mobile push suppression was not exercised; these captures cover the local web client's in-app notifications.
A real one-hour wait or disconnected-client replay was not run; the delayed-processing case advanced only the browser wall clock past wake while preserving server completion timestamps.
Sync 1114c: 144 upstream commits to 8bd7f46. Two additive conflicts:
ThreadNotificationCoordinator.tsx keeps the fork completion-hold filter beside
pingdotgg#27458's snoozed check; SidebarThreadRow.tsx keeps the fork idle-crew unread
guard on top of pingdotgg#28616's row status. The fork session_* end-to-end tests
follow pingdotgg#36821 (CheckpointStore mock, isNonGitProject).
