Ended iOS Live Activities could remain visible after opening the app or signing out because active-activity discovery excludes them. This adds a factory-scoped native cleanup during reconciliation and sign-out. Foreground reconciliation preserves active and stale activities; sign-out keeps the existing behavior of ending active activities too. Opening the app can also clear a recently completed card before its normal dismissal delay expires.

The Expo Widgets patch exposes the cleanup consistently through the native bridge, runtime JavaScript, public types, and non-iOS stubs. A missing native method is caught so older development clients still discover and register their active activities.

Built on @only21mil’s work in #21307; fixes #16241. The factory cleanup would be useful upstream in Expo Widgets.

Validation: the existing remote-registration suite remains 39 tests (37 on main); the rewritten foreground test drives the actual AppState listener. With main application sources restored, 36 pass and 3 fail; after restoring the candidate, all 39 pass. Mobile typecheck, scoped lint, formatting, and patch/hash consistency checks pass. Independent fresh Opus and Sol reviews found no confirmed code blockers.

After capture, merged main 54983e3 into the original branch as a26a2e0. All four feature source/test files, the complete widget patch, and the lockfile remain byte-identical to the verified candidate. The 39 focused tests, mobile typecheck, scoped lint, and all 11 installed patched-file checks pass after that integration. This also brings in the unrelated web-test fixture fix that blocked the earlier CI run.

Native verification used a fresh EAS iPhone simulator development client for each native graph, production JS, and the same isolated fixture. The fixture uses real ActivityKit objects, the production AppState listener, and setAgentAwarenessRelayTokenProvider(null); it does not replace native callbacks. The baseline application sources and native dependency graph are from main 4ac8fa4; candidate sources are a530b2d. The baseline build metadata names the candidate checkout with the exact main patch/lock overlaid for upload, rather than a clean-main checkout.

On the baseline main revision, an ended A remains frozen in Notification Center after reopening. On the candidate, reopening removes A without starting another activity. With ended A plus active B, B retains its exact ActivityKit ID and accepts an awaited native update to revision 1. The baseline stack is expanded; the candidate capture shows its collapsed card preview. The candidate preview alone does not enumerate every system card; the A-only and sign-out cases independently establish removal. A separate fresh-seed sign-out case calls the production export before any Home/reopen transition. Main ends active B but retains frozen A; the candidate has no active IDs and an empty Notification Center.

The fixture uses synthetic card data and a null-returning credential provider. This verifies native cleanup and the production lifecycle/export path, not real account UI, APNs/relay delivery, natural eight-hour expiry, a physical locked screen, or Release builds. A was manually ended with ActivityKit’s default policy. Android has no ActivityKit behavior to exercise; web and desktop are unaffected.

Before — baseline main after reopening, ended A remains:

After — candidate after reopening, no retained card:

Before — main retains frozen A alongside updated B after foreground:

After — B retains its native ID and shows revision 1 after foreground/update:

Approvability

Verdict: Approved at b595a94

Macroscope's review found this PR approvable — This is a contained iOS Live Activity bug fix that reuses existing native cleanup, preserves active cards, and adds regression coverage for foreground, sign-out, and older-binary behavior. The remaining lockfile and platform adapter changes are mechanical and do not introduce a new workflow or product default.

📝 Walkthrough

The change adds an API to dismiss ended Live Activities. The native implementation dismisses matching ended activities, and mobile cleanup invokes the API during local cleanup and active-activity reconciliation. Tests cover foreground dismissal, errors, and cloud sign-out.

Changes: Live Activity cleanup

Layer / File(s)	Summary
Expose native ended-activity dismissal patches/expo-widgets@58.0.20.patch	LiveActivityFactory.dismissEnded() dismisses ended activities that match the factory name. The JavaScript and native module expose the method. start() calls it before requesting a replacement.

Merge Risk: ⚪ Minimal · up to a530b

Foreground and sign-out cleanup can dismiss completed Live Activities without interrupting active-activity handling. No merge-blocking issue remains after normal checks.

Security architecture risk: 🔵 Low · up to a530b

The change is limited to dismissing already-ended Live Activities belonging to the existing activity factory. Active activities and registration authentication retain their existing controls. Cleanup remains asynchronous and best-effort, so immediate removal after sign-out is not guaranteed by the inspected implementation.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

• inferred — The new mobile cleanup call can target all ended activities matching the AgentActivity factory on the local installation, rather than one activity ID. The native predicate excludes active and stale states and does not select activities belonging to a different factory name. This is factory-scoped cleanup, not an account-identity check.

Trust Boundaries and Controls

• observed — The new cleanup method takes no caller-supplied activity ID, token, or payload; the bridge invokes the supplied factory object and native code applies its name and state filters. Remote registration continues through the existing token-bearing client call rather than through the cleanup bridge.

Resilience and Maintainability Implications

• inferred — The added sign-out call addresses ended cards that existing active-activity cleanup could miss, but it should not be interpreted as a transactional privacy-erasure guarantee. Native completion is unacknowledged, and synchronous compatibility failures deliberately allow the remaining lifecycle work to continue.

Full details: Linked Issues check

Explanation

For directly linked issue [#16241], the PR adds factory-scoped dismissEnded() cleanup with the factory name and .ended filters. Foreground reconciliation calls the cleanup before active-activity discovery. start() retains cleanup for new cards. Tests cover idle foreground cleanup, continued active-activity registration when cleanup fails, and the sign-out path.

Explanation

The description is complete and follows the required structure. It explains the problem, implementation, scope, linked issue, focused verification, limitations, screenshots, recording, and tooling. It does not quote an explicit maintainer approval comment, but the linked bug and focused scope provide sufficient context.

Full details: Out of Scope Changes check

Explanation

The cleanup bridge, runtime helper, reconciliation changes, sign-out reuse, and regression tests support [#16241] or its related lifecycle path. However, patches/expo-widgets@58.0.20.patch also adds widgetRenderingMode and isLiquidGlassAvailable to LiveActivityEnvironment and changes Live Activity rendering to use those values. The supplied scope evidence does not connect these iOS 26 rendering changes to [#16241] or to ended-activity cleanup.

Resolution

Remove the unrelated widgetRenderingMode/isLiquidGlassAvailable rendering changes from this PR, or link and document a coding requirement that requires them.

apps/mobile/src/features/agent-awareness/remoteRegistration.test.ts: 1

505-520: 🎯 Functional Correctness | 🔵 Trivial | ⚡ Quick win

Trigger the AppState listener in the idle-foreground test.

The test calls refreshActiveLiveActivityRemoteRegistration() directly, so it does not exercise the app-foreground callback. The neighboring test covers that callback only with an active activity. A future idle-only guard could skip refresh while all current tests still pass. Invoke appStateMock.listeners with "active" and assert dismissEnded before getInstances.

Suggested fix

       return Effect.gen(function* () {
-        yield* refreshActiveLiveActivityRemoteRegistration();
+        yield* runBackgroundOperations();
+        widgetMocks.dismissEnded.mockClear();
+        widgetMocks.getInstances.mockClear();
+        for (const listener of appStateMock.listeners) {
+          listener("active");
+        }
+        yield* runBackgroundOperations();

         expect(widgetMocks.dismissEnded).toHaveBeenCalledOnce();

Taking over this one for the mobile-02 maintainer batch. I’ll merge current main, keep the regression tests focused, rebuild the implementation to current conventions, and run independent reviews plus fresh iOS simulator verification. Credit to @only21mil for the original cleanup fix and reproduction.
