Problem

On mobile, archiving or deleting a thread throws away that thread's earlier Undo (Settled, Snoozed, or Unpinned) before the request goes out. If the server rejects the archive or delete, the app shows the error and the thread stays in the list, but the Undo the user still had a few seconds left on is gone. So a user who settles a thread by mistake and then fails to archive it can no longer undo the settle.

Change

executeAction in apps/mobile/src/features/home/useThreadListActions.ts now expires those Undos only after the archive or delete succeeds. Web already works this way: #25444 expires them after the Failure early return in useThreadActions.ts, and useThreadActions.undo.test.ts covers it with "keeps the earlier Undo when the request fails". Un-settle still expires the Settled Undo before its request, the same as on web.

Scope and approval

This is a very small fix for an obvious bug, so there is no prior issue. It moves one existing block to after the failure return so mobile matches the behavior web already tests. Overlap search: the local PR index and gh search prs for "mobile undo archive" and useThreadListActions turned up nothing on these lines. Open #29564, #26578, #24917, #24522, and #26826 touch the same file, but none of them changes the archive/delete expiry.

Verification

• Red on main: the new test thread action undo > keeps the earlier Undo until archiving succeeds fails with AssertionError: expected undefined to be 'Settled' right after the failed archive.
• Green: cd apps/mobile && vp test run src/features/home/useThreadListActions.test.ts passes 42/42.
• vp run check:changed passes: format, lint, knip, typecheck (2 packages), tests, react compiler.
• Not checked: no capture on a device, because nothing visual changes. The test runs archive only. Delete goes through the same block, but its confirm callback is fire-and-forget and can't be awaited without polling.

Approvability

Verdict: Approved at 9c91cf2

Macroscope's review found this PR approvable — Mobile now invalidates earlier Undo offers only after archive or delete succeeds. The reported pending-request Undo issue remains subject to the separate correctness gate; no additional material risk requires human judgment.

Notes:

• This verdict was updated automatically after the outstanding correctness findings were resolved. Macroscope did not re-review the code.

- Around line 157-159: Update the undo flow associated with
ThreadUndo.invalidate so the Undo claim remains current while an undo is in
flight and is retained when the undo fails. Use the result from
executeThreadUndo to distinguish success from failure, and prevent a concurrent
tap from finishing the earlier claim; only dismiss or release the claim after a
successful undo.

Walkthrough

Archive and delete actions now preserve settle, snooze, and pin undo claims when an action fails. They invalidate those claims after a successful action. A regression test checks the Settled notice behavior.

Changes: Undo claim lifecycle

Action invalidation and regression test apps/mobile/src/features/home/useThreadListActions.ts, apps/mobile/src/features/home/useThreadListActions.test.ts	Archive and delete actions invalidate settle, snooze, and pin undo claims only after success. A regression test verifies that a failed archive preserves the Settled notice and a successful archive clears it.
