+Finish delivery of #2895 and its bounded #2896 reminder-save ownership follow-up. The latter replaces a component-wide boolean with a request identity so an older account's completion cannot discard a newer account's unsaved hours. Its reproduced interleavings, full frontend suite, typecheck/build and lint pass. Keep the final #2808 completion record tied to the merged delivery receipts.
+
 The #2893/#2894 recovery follow-up is implemented in [PR #2895](https://github.com/Chris0Jeky/Taskdeck/pull/2895): preserve reminder drafts, report concurrent question writes accurately and align model payloads with the evidence preview. Keep the existing privacy/revision/usage boundaries, prove the reproduced cases and publish one reviewed follow-up. Local full suites, focused final payload checks, browser recovery and bounded independent review pass.
 
 Merged #2892 as 93eab3443 after required run 34453924959 passed at reviewed head 42965edde. The reminder-hours slice under #2808 delivers: optional named-zone weekly windows, explicit save/recovery, existing shared budgets and server-side eligibility. Local full backend/frontend, combined privacy/recovery and cross-browser proof pass. The final active-account write condition prevents erased private hours from being restored by an in-flight request. Old opted-in users retain unrestricted behavior; reminders remain default off.

+Reminder save ownership (#2896): a delayed completion from a previous account can no longer release the guard for a newer account's enable save. Both success and failure interleavings were reproduced before repair; 22 targeted component cases and the full 6,438-test frontend suite pass, with three existing skips. Typecheck, production build and scoped lint pass. This is a focused follow-up to #2895; the delivery tracker records its hosted gate and merge receipt.
+
 Final overhaul recovery follow-up (#2893/#2894, [PR #2895](https://github.com/Chris0Jeky/Taskdeck/pull/2895)): retain an unsaved hours draft across enable-only saves and confirmed validation rejections, distinguish competing question writes from source changes, and send the model exactly the previewed excerpt. Final frontend passes 6,436 tests with three existing skips; full backend passes 9,315 with 34 existing skips, followed by 17 API and 19 application tests for the final payload correction. Build/typecheck, scoped lint, browser recovery and bounded independent review pass. Required hosted runs 34458797270 and 34462673996 passed at reviewed heads f39cc6cf3 and d25edf2a5, including both operating-system suites and browser smoke. The PR records subsequent base qualification and the final merge receipt. The source and draft regressions were reproduced before repair; the validation ledger records their scope.
 
 Optional reminder hours (#2808, merged #2892): explicit weekday and time windows in an IANA zone, including overnight and daylight-saving behavior. Server checks precede question lookup and budget admission; preference edits preserve the shared UTC allowance, old-client toggles retain the window, and exports include it without a new migration. The slice passed 9,270 backend and 6,421 frontend tests, with 34/three existing skips respectively. After parent integration, 56 API tests, 56 component tests, typecheck/build and five Chromium journeys pass, including a reproduced and fixed account-erasure race. Firefox and mobile Grove/Grove Night evidence are recorded in the validation ledger. Required CI run 34453924959 passed at reviewed head 42965edde; #2892 merged as 93eab3443.

 # Workspace overhaul validation and follow-through
 
+## Reminder save ownership follow-up (2026-09-10)
+
+Issue #2896 covers a late-review account-switch interleaving: account A's save is pending, account B
+loads settings and starts another enable save, then A settles before B. Both resolved and rejected A
+responses reproduced replacement of B's unsaved zone with its saved zone. A unique request identity
+now lets only the owning completion release the component guard. Both regressions pass within 22
+attention component tests and assert an explicit later hours save using B's returned revision.
+
+Full frontend qualification passes 6,438 tests with three existing skips across 416 files; typecheck,
+production build and scoped ESLint pass. The backend is unchanged. The deterministic component tests
+exercise the actual shared store and account-generation checks; no new physical-device or live-provider
+claim is made. The follow-up PR records its independent review and hosted delivery receipt.
