With in-app notifications enabled, complete a turn while viewing another thread, then open the completed thread from the sidebar or a keyboard shortcut. Its notification remains visible until expiry or its own action is used. Input and approval notifications have the same behavior.
Track outstanding in-app toast IDs per environment and thread. Opening the matching thread closes its toasts while preserving unrelated notices. Normal closure releases ownership; coordinator unmount closes the notices it owns.

Triaged bug via the automated issue flow. This changes the shared web coordinator used by web and desktop. Native mobile paths, provider behavior, and wire contracts are unchanged. Reproduction-only scripts and their Knip registrations were removed from the diff; the public artifacts below preserve the setup.
Current head: 23cff43, merged with main c79ef8c. The test-file conflict preserves both this fix’s cases and main’s compaction case. The production diff remains limited to the coordinator and its existing tests.
cd apps/web && vp test run src/components/ThreadNotificationCoordinator: 8/8 passed.vp run check:changed: format, lint, knip, affected typechecks and focused tests passed.Current-head proof audit: INSUFFICIENT. Independent audit confirms missing R2/R3/C0 chapters, expired witnesses and uncertified timing. Recording event offsets require an explicit mapping to media time. Current-head evidence remains INCOMPLETE. New evidence index, eight recordings, drivers, checkpoint diffs and validity report. Before is current main; After is the integrated head above. R1 reproduced retained notices on main and selective dismissal after the fix. R2/R3 contain missing or invalid chapters; 390/dark covers R1 only. Only 32 of 109 stability checks were byte-identical. The full R1/R2/R3/C0 matrix has not passed. Desktop shell, relay and tunnel execution remain unverified. The bugfix handoff label is withheld.

The following refers to the earlier head and is not acceptance evidence for the integrated head.

The original route and unmount regressions failed before the fix.onClose for dismissal, action, expiry, Escape, and swipe; the bot's suggested callback relocation is unnecessary.Independent proof audit: INSUFFICIENT R1, R2, R3, C0. Detailed audit.
Evidence is incomplete and does not satisfy the fixture matrix. Only two of eight required recordings were captured. Six dark/narrow recordings and environment removal are missing; Before's first navigation checkpoint lost its completion toast before capture. Thirty-five of 44 screenshot twin pairs were not pixel-identical. Reduced motion was not configured. Desktop's Electron shell, relay, and tunnel paths were not exercised.

Partial R2 sequence: produce completion and approval notices for V plus an unrelated failure for W, then open V from the sidebar. Before retained all three; After retained only W. Before recording checkpoints are at driver 53.284s and 58.410s; exact After checkpoints and route events are in the linked index. These stills are supplemental, not settled acceptance proof.

What else changed in these frames: sidebar creation ordering and selection, activity indicators, hover/focus, and antialiasing differ between phases. The removed toasts and their shadows uncover the right panel. The unrelated differences prevent a clean visual-regression claim. No claim is made that nothing else changed.

Verdict: Approved at 23cff43
Macroscope's review found this PR approvable — This focused web bug fix manages existing in-app notification toasts so they close when their thread is opened or notifications are disabled. The production change is localized and covered by targeted browser tests, with no schema, configuration, or sensitive-area impact.

The notification coordinator now tracks in-app toast IDs by thread. It closes a toast when its thread becomes active and closes remaining tracked toasts when the coordinator unmounts. Browser tests cover route changes, notification settings, and matching environments and threads.

Explanation
Issue [#20883] requires completion, input, and approval toasts to close when another route opens the matching thread. EnvironmentNotifications records each in-app toast ID with its thread ID, closes matching IDs when useParams changes, and removes ownership on close. Its cleanup closes owned toasts on unmount. The browser tests cover route-driven closure, notification disabling, environment and thread filtering, and repeated notices.
Explanation
The pull request changes only ThreadNotificationCoordinator.tsx and its browser test. The coordinator change implements [#20883]. The test changes provide automated coverage for the same behavior. No unrelated production or test changes are present in the reviewed diff.
Explanation
The description is complete and follows the required Problem, Change, Scope and approval, and Verification sections. It identifies the issue, explains the implementation, documents focused test results, reports verification limits, includes UI evidence, and names the models and harnesses used. The scope section references triage but does not include an explicit maintainer approval comment; this is a minor completeness gap because the fix is linked to a triaged bug.

apps/web/src/components/ThreadNotificationCoordinator.tsx:202-233🩺 Stability & Availability | 🟡 Minor | ⚡ Quick winRemove toast ownership when the toast closes.
The dismiss button reads
toast.data?.onClose, but this callback is stored at the toast payload’s top level. Manual dismissal therefore leaves the toast ID intoasts. TheOpen threadaction also closes the toast without deleting its ID. Repeated notifications can leave stale entries in the environment ownership map until route cleanup or unmount.Use one ownership-cleanup helper for the dismiss callback and the direct close path.

Verified the toast ownership review finding against Base UI 1.5.0: manager.close, timers, Escape and swipe all call store.closeToast, which invokes the top-level toast.onClose callback. The existing callback therefore removes ownership on dismissal and the Open thread action. Moving it to data.onClose would omit timer and swipe cleanup. No production change is needed for that finding. PR-only proof scripts and their Knip entries were removed in 4fbf29c and uploaded as external evidence links in the description.
