fix(web): opening a thread dismisses its notification toasts - #24313
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.
Change
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.
Verification
Integrated-head validation
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.
Independent Codex and Claude code reviews found no concrete code defect. Evidence acceptance remains pending.
GitCafe status reported 30 successful checks, no pending/failing checks; GitHub conflict evaluation for the new head was pending at the status read.
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.
cd apps/web && vp test run src/components/ThreadNotificationCoordinator.badge.browser.test.tsx: 5 tests passed at cleanup head 4fbf29c. The original route and unmount regressions failed before the fix.
Scoped server Knip file check passed after removing the proof scripts and registrations.
Independent Codex and Claude reviews found no production defect. Both verified that Base UI invokes top-level onClose for dismissal, action, expiry, Escape, and swipe; the bot's suggested callback relocation is unnecessary.
Targeted lint/typecheck and diff checks passed during code review.
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.

…ing its thread
The completion toast should close once the route opens the thread it
announces; it currently stays visible.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
In-app toasts only closed through their own "Open thread" action, so a
thread opened from the sidebar or anywhere else left its toast showing.
Each environment now remembers the toasts it raised per thread and
closes them when the route lands on that thread. The test's params mock
reads from an atom because the React Compiler memoizes children that a
plain getter would never re-render.

Turning in-app notifications off while notification mode is off unmounts
every EnvironmentNotifications, and the toasts each one tracked are lost
while the toasts themselves stay on screen. Nothing can close them after
that, so this pins the cleanup to the moment they are disabled.

Merge Risk: Low · up to 3e638
Opening a promoted draft can leave its thread notification visible until navigation completes or the toast closes. The change is mergeable with owner awareness of this narrow gap.

Explanation
Issue [#20883] requires completion, input, and approval toasts to close when another route opens the matching thread. The coordinator tracks toast IDs by environment and thread, subscribes to resolved routes, and closes only the active thread's IDs. The shared toast path covers all notification kinds. The browser test verifies matching completion and approval closure, preserves an unrelated thread toast, and closes remaining toasts when notifications are disabled.

Explanation
The production diff changes the shared thread notification coordinator. The test diff adds coverage for the same toast ownership and route-closure behavior. These changes implement [#20883]. No unrelated production or test changes are shown.

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 in toasts. The Open thread action 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.
…dinator
Main replaced the React coordinator with startThreadNotifications, so the
merge takes main's file and re-adds the behaviour there: an onResolved route
subscription closes the opened thread's in-app toasts, and disabling all
notifications or tearing the coordinator down closes the rest.

Resolve promoted drafts when dismissing thread toasts.
A promoted draft can remain on its draft route before the server route takes over. During that time, matching toasts can remain visible, and a new toast can appear for the open thread.
Use resolveThreadRouteTarget and resolveActiveThreadRouteRef for the active-thread check. Also update dismissal when the draft store changes, and unsubscribe during cleanup.

Enable in-app notifications and Supervised permissions. With B focused, create A's input, completion, or approval notice and an unrelated completion notice through replay turns. Open A using Ctrl+Shift+[ for input or the sidebar for completion and approval, without using the toast action.
Both environments: Chromium web on Linux, 1280×800, light theme, fresh synthetic data. The scenario failed on base and passed on head. Base retained A's notices; head dismissed each while preserving the unrelated notice.
AI-assisted; verified with the tests and tools listed above.
Not shown:
Cross-environment isolation was not exercised; only one fresh local environment was connected.
Multiple simultaneous notices for the same thread were not exercised; each target thread produced one notice.
Disabling all notifications and coordinator teardown cleanup were outside this navigation scenario.
Turns were launched through the app CLI while B was open; typing in A and then switching away was not separately captured.
