Problem

A Claude Monitor wakes the agent once for every line it prints. T3 runs each wake as a new run, the agent replies "Waiting on the sweep." and the run ends as completed, so web and desktop show "Thread completed" and play the completion sound after every Monitor event while nothing has finished. In the thread from #32497 this was 47 alerts in 16 minutes.

Change

ThreadNotificationCoordinator already treats a stopped run as quiet. It now also treats a completed run as quiet when:

• the run was not started by the user (latestRunRequestedAt is newer than latestUserAuthoredMessageAt, which excludes wakes), and
• a monitor is still pending in pendingBackgroundTasks.

The user's own run, the run after the Monitor ends, and attention alerts (approval, input, failure) still notify. Servers that don't send latestUserAuthoredMessageAt keep the current behavior. Pull request watches are also monitor tasks, but they are awaited, so they already keep the thread out of ready and are unaffected.

Web (local and app.t3.codes) and desktop both get this, since the Electron window runs the same coordinator. Mobile push comes from the server relay (projectThreadAwarenessV2) and is not changed here: the relay keeps a thread visible while it is running, so mapping a wake to running could leave a Live Activity open behind a long-lived watchdog Monitor. That needs its own decision.

Scope and approval

Fixes #32497. A small fix for an obvious bug, limited to the client notification gate. It doesn't change the sidebar status, settlement, or the server.

Verification

• New case in ThreadNotificationCoordinator.badge.browser.test.ts: a user run, three Monitor wakes, then the wake after the Monitor ends. On main it fails with 5 "Thread completed" notifications. With the fix there are 2 (the user's run and the final run) and 2 sounds.
• vp test run src/components/ThreadNotificationCoordinator.badge.browser.test.ts src/components/ThreadNotificationCoordinator.logic.test.ts (in apps/web): 14 passed.
• vp run check:changed passes (format, lint, knip, typecheck, tests, react compiler).
• Full apps/web unit and browser suites: the only failures (GuestPage, chatRouteCommands, pcmWorklet) fail the same way on main on this machine.
• Checked against real data on two machines before relying on the timestamp comparison: across 2,501 runs, no user-started run had requestedAt later than its message's updatedAt.

Manual check with a real Claude Haiku 5.5 thread on a dev server, with in-app notifications on and viewing a different thread the whole time. The prompt starts a background loop that writes 6 lines about 8 seconds apart and a Monitor that prints each line. Each thread had 8 runs: the user's run, 6 wakes that reply "Waiting on the sweep.", and a final "Sweep finished" run. The overlay at the top was added only for the recording. It counts the app's own "Thread completed" toasts and shows a clock.

	Before (main)	After
"Thread completed" toasts	7	2 (user's run, final run)
Recording	before-main.mp4	after-fix.mp4

Before, at the end of the run (7 toasts):

After, partway through the Monitor wakes (still 1, from the user's run):

After, at the end of the run (2 toasts):

Not checked: the OS notification path on a packaged desktop build (the manual check used in-app toasts, which come from the same gate), mobile push, and a live Grok session (Grok also reports monitor tasks, so the same rule applies to it).

Approvability

Verdict: Approved at fad7036

Macroscope's review found this PR approvable — Suppresses misleading “Thread completed” alerts for Monitor-triggered intermediate runs while retaining attention notifications. The change is limited to notification presentation and preserves existing behavior when server timestamp support is unavailable.

Walkthrough

The notification coordinator now identifies Monitor wake runs and treats them as quiet observations. A browser test covers repeated Monitor wake runs and a later completed run after the pending task clears.

Explanation

[#32497] The client gate suppresses Monitor wake completion notifications and sounds. The regression test covers repeated wakes and a final completion. The PR leaves the reported sidebar status behavior and server-side phone awareness unchanged. Evidence does not establish whether opaque Monitor wakes already have the required labels.

Resolution

Keep pending Monitors visible as Waiting and apply equivalent wake handling to phone awareness. Verify Monitor event labels and preserve terminal-event labels.

On the "Linked Issues check" warning: this is intentional scope, not a gap in the fix.

#32497 marks the notification change as the main ask and lists the rest as hardening. Per CONTRIBUTING's one-problem-per-PR rule, those parts are separate changes:

• Sidebar "Waiting" for a pending Monitor: changes sidebar status for every thread with an unmarked Monitor, including dev-server watchdogs. That is a product decision of its own.
• Phone awareness: covered under Change in the description. Mapping a wake to running in projectThreadAwarenessV2 keeps the thread visible on the phone after settlement, so a long-lived watchdog Monitor could leave a Live Activity open. That needs its own design and a device to test on.
• Wake message label ("Background task completed."): server-side text in ProviderContinuationService, unrelated to whether a notification fires.

This PR stops the desktop and web "Thread completed" alerts and sounds for Monitor wakes. That is the user-facing problem reported in #32497.

Thanks for this. Main already has the change, as of 20723d6.

Already covered by 20723d6d9b, landed through #32520. Main classifies background progress wakes explicitly, holds web/desktop completion notifications while a Monitor remains pending, preserves attention alerts and user completions, and includes coordinator regression coverage. It also handles Monitor removal, final-wake duplicate prevention, and mobile awareness. #32497 is already closed. All 37 pages of open PRs were inspected; no separate open PR needs to be preferred. No project code, tests, or scripts were executed.

Closing as superseded.
