Stacked on #12046. expo-widgets 58 exposes ActivityKit's staleDate. The relay already sets a ten-minute stale-date on every push, but the two activities the app starts locally (arming a card for local work, priming from a snapshot) had none, so a card whose relay registration never landed could look alive forever.

Locally started activities now carry the same window, and the layout reads environment.isStale: in-flight rows turn into "Out of date" with the neutral clock glyph and the header says "Agent status out of date", while completed and failed rows keep their state.

Validation: 13 AgentActivity layout tests pass, including a new one for the stale environment. Mobile typecheck clean.

Model: Claude Fable 5. Harness: Claude Code.

Locally started and snapshot-primed Live Activities now receive a 10-minute stale deadline. The widget presents stale non-terminal activities as out of date while retaining completed and failed states.

Stale non-terminal activities use the "Out of date" status, secondary foreground tint, and stale labels. Completed and failed activities retain their existing states. A regression test covers the updated presentation.

Stale activities now visibly degrade, but the minimal view still shows the logo and the expanded view still displays an outdated active-agent count. Mergeable with owner awareness of these remaining presentation gaps.

🟡 Minor · Render the stale clock glyph in the minimal presentation.

apps/mobile/src/widgets/AgentActivity.tsx:366-368
🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Render the stale clock glyph in the minimal presentation.

When an activity is stale with only in-flight rows, attentionRow, failedRow, and allDone are all false. This branch renders the T3 logo instead of clock.arrow.circlepath. Include the stale hero phase in the glyph condition.

Approvability

Verdict: Not approved

Macroscope's review found this PR not approvable — This changes the default iOS Live Activity lifecycle by automatically adding a ten-minute stale deadline to locally started and primed cards, along with new user-visible stale rendering. Because the behavior is automatic rather than opt-in, human review is warranted.

Notes:

  • Diff unchanged. Approvability was decided on eligibility alone.

You can add or adjust custom eligibility rules. Learn more.

🟡 Minor · Hide the stale active count in the expanded view.

apps/mobile/src/widgets/AgentActivity.tsx:373
🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Hide the stale active count in the expanded view.

When environment.isStale is true, this view still renders ${props.activeCount}. The banner and compact views show an out-of-date status instead. Replace this count with stale presentation so the expanded view does not present stale work as active.

expo-widgets 58 exposes ActivityKit's staleDate. Locally started activities
now carry the same ten-minute window the relay already puts on every push,
so a card whose registration never reaches the relay stops claiming an
agent is working. The layout reads environment.isStale and turns in-flight
rows into "Out of date" with the neutral clock glyph, keeping terminal rows
as they were.
