[BucciMobile]

Ported from BucciMobile/edge-copy#22 (branch vibe/morning-brief-data-gate-8ff4f0, head a0dc197f), where CI is green (flutter analyze + all test suites) and 5 CodeRabbit review rounds are addressed.

Why

The notification "Your morning briefing is ready" fired at a fixed 08:00 local time whether or not the band had synced — including mornings where the user was still asleep and mornings where the overnight data had not arrived yet. Tapping it lands on AiBriefingScreen(period: morning), which can only summarize the data actually on device, so the notification was a promise the deep link could not keep. The evening AI slot never had this problem: it is armed only when the nightly sweep produced a finding (sweepHeadline != null), and that finding is the notification body. This PR gives the morning briefing the same honesty contract, plus a wake-aware fire time.

What the user sees

• Before: every day at the configured time (default 08:00), a "Your morning briefing is ready" notification — even with no data synced for the night that just ended, and even while still asleep.
• After: the notification fires only once last night's data has actually arrived (a synced band sample dated today, or a derived day row for today — the latter also covers cloud sources like Oura). The slot is armed for today's occurrence only: if the morning sync lands just after the slot time, the briefing fires ~2 minutes later (3-hour grace window, quiet hours checked on the final instant; beyond the window the slot stays unarmed until the next day's pass re-establishes readiness). With a measured typical wake, the slot moves to max(configured time, wake + 30 min). Each day's briefing is announced at most once; a disabled preference cancels a pending one; a changed time replaces it.

How it works

OS-scheduled notifications fire with no Dart running, so every check happens at arm time in the pure plan (lib/ai/reminder_plan.dart, lib/notify/notification_center.dart):

• aiReminderPlan gains lastNightDataReady (morning slot omitted when false, mirroring the evening slot's sweepHeadline != null rule) and typicalWakeMinOfDay, resolved by morningBriefSlotMin = max(morningMin, wake + 30 min), still quiet-hours-capped (a wake-derived slot the cap would move before its own minimum is omitted).
• scheduleAiReminders is serialized through _synchronized; the morning slot arms for today only (ahead of the slot or inside the late-fire grace window, quiet-checked); a persistent per-day FiredKeyStore guard (morning_brief_announced:<date> + morning_brief_slot:<date>:<slotMin>) distinguishes armed/pending from delivered, preserves a matching pending occurrence, replaces one whose time changed, releases the guard when an undelivered registration is cancelled, and records it only when scheduleOnce (now returning success) actually registered.
• AppState._lastNightDataReady checks a fresh LocalDb.latestSample() (before the cached lastSynced) for today's day label, or a settled crossday recent[] row dated today; the typical wake comes from the same crossday read as bedtime. _onDataStored re-arms reminders after every durable sync store.

Localization

No notification title/body strings changed — no new .arb keys; app_en.arb and all translations plus display_text.dart are untouched, existing translations keep applying.

Verification

• flutter test --concurrency=1 test/ai_reminder_plan_test.dart test/ai_morning_brief_arming_test.dart test/ai_reminders_local_endpoint_test.dart → +40: All tests passed! locally on a0dc197f.
• CI on the edge-copy PR (improved sync, storage tables and compute #22): flutter analyze + full test suite green.
• No kAlgoVersion bump (notification scheduling policy only, no analytics output). No new dependencies.

Summary by Sourcery

Make morning briefing notifications data-backed, wake-aware, and safe against duplicate or stale scheduling.

New Features:

• Gate morning briefing notifications on the availability of the previous night’s data.
• Schedule morning briefings relative to the user’s typical wake time while respecting configured times and quiet hours.
• Support same-day late delivery after morning data arrives, with a grace window and at-most-once delivery.

Bug Fixes:

• Prevent morning briefings from firing without data or being scheduled for a future day based on stale readiness.
• Ensure notification state is not incorrectly recorded when scheduling or cancellation fails, and avoid duplicate or stale pending briefings when settings change.
• Restrict latest-sample readiness checks to primary-band data and correctly select the newest record across sample stores.

Enhancements:

• Serialize and coalesce reminder scheduling triggered by concurrent sync and lifecycle events.
• Add persistent per-day morning briefing guards with replacement, delivery, release, and retention handling.

Tests:

• Expand reminder-plan and morning-briefing coverage for data readiness, wake-aware timing, quiet hours, grace-period delivery, and same-day arming.
• Add tests for coalesced scheduling and persisted notification guard behavior.

Summary by CodeRabbit

• New Features
  • Morning AI briefings can be timed using your typical wake time and are scheduled only when last-night data is ready.
  • A briefing may still arrive up to three hours after its planned time, unless delivery would fall during quiet hours.
• Improvements
  • Reminder schedules update when relevant data changes. Already-delivered briefings and matching pending reminders are preserved, while reminders for changed times are rescheduled.
  • Briefings that miss their late-delivery window are not rolled forward to the next day.
  • Reminder timing reflects the latest available sleep data as it is stored.
• Bug Fixes
  • Sleep data selection now compares the newest records across supported sources while limiting legacy records to the primary device.

Walkthrough

AI morning reminders now require ready last-night data and can use typical wake time to set their slot. App state derives wake and readiness inputs. Notification scheduling supports late delivery within a three-hour window and tracks pending and announced briefings.

Changes: AI Morning Reminders

Layer / File(s)	Summary
Derive reminder inputs lib/state/app_state.dart, lib/state/coalescing_runner.dart, lib/data/db.dart	App state parses wake data, checks last-night data readiness, and re-arms reminders after durable data storage. Reminder passes are serialized and coalesced. The latest-sample query compares decoded samples with primary-device rows.
Calculate the morning slot lib/ai/reminder_plan.dart	The morning slot uses the configured time floor or, when available, the later of that floor and typical wake time plus 30 minutes. The plan requires ready last-night data and applies the quiet-hours cap.
Report and maintain notification state lib/notify/notification_service.dart, lib/notify/fired_keys.dart, lib/data/db.dart	The service reports one-shot scheduling and cancellation results, and returns pending notification IDs or null if the query fails. Fired-key storage supports expiry for embedded dates and prefix release.
Schedule and track briefings lib/notify/notification_center.dart	The notification center handles late delivery within a three-hour grace period and uses announcement and slot state when preserving, cancelling, or re-arming briefings.

Explanation

The title names the main behavior change: the morning briefing is armed only when last night's data exists, and it is timed after the typical wake time. The changeset adds readiness gating (lastNightDataReady) and a wake-based slot (morningBriefSlotMin with a wake + 30 minute floor), so the title matches the primary change. It omits the related per-day dedupe, serialization, and re-arming work, which is acceptable for a title.

**Ready briefings get cancelled**

When overlapping reminder passes read readiness in one order but reach the serialized scheduler in another, `_ensureRemindersScheduled` can submit an older `lastNightDataReady: false` after a newer ready pass; `scheduleAiReminders` then cancels the newly armed briefing, so the user gets no alert until another pass runs.

Serialize the readiness reads together with scheduling, or reject stale passes before they can replace a newer plan.

</code_context>
<issue_to_address>
**Peripheral samples unlock briefings**

When there are no decoded primary-band rows and the newest row in `samples` is from a peripheral sensor dated today, `LocalDb.latestSample()` can fall back to the newest row in `samples` when there are no decoded primary-band rows; `_lastNightDataReady` accepts any returned sample dated today. A peripheral sensor sample therefore arms a briefing without the band data the notification promises.

Require the readiness sample to come from the primary band source, including in the fallback query.

</code_context>
<issue_to_address>
**Partial overnight data triggers briefing**

When a sync stores a sample dated today while the overnight derivation is still building or truncated, `_lastNightDataReady` returns true as soon as it finds a sample dated today, bypassing the unsettled crossday row; the scheduler arms the alert while the overnight is still building, and the user can be told a briefing is ready before it can be generated.

Require the overnight status to be ready before treating a same-day sample as sufficient, or otherwise gate arming on the same settled-data condition used by briefing generation.

+
</code_context>
<issue_to_address>
**Pending briefings are suppressed**

When the pending-notification query throws while the scheduler is checking or changing today's morning briefing, `pendingIds()` turns the query failure into an empty set, so `scheduleAiReminders` treats an unknown pending state as no pending notification and preserves `announcedKey` as if the briefing was delivered. The briefing is then suppressed for the rest of the day.

Preserve pending-query failures as a distinct state and make the scheduler avoid treating them as proof that the briefing was delivered or is not pending.

-    await svc.cancel(NotificationService.idJournalLog);
</code_context>
<issue_to_address>
**Failed cancel leaves stale alert**

When the plugin throws while cancelling a previously armed morning notification, `NotificationService.cancel` swallows plugin errors, so a failed cancellation leaves an older morning notification armed even though this pass excluded the slot for missing data, quiet hours, or a disabled preference. The OS can then deliver the unsupported briefing anyway.

Make cancellation failure observable and retry or verify removal before treating the morning slot as cleared.

+  return afterWake > floor ? afterWake : floor;
+}
+
</code_context>
<issue_to_address>
**Briefings arrive before wake**

When the typical wake time plus 30 minutes wraps past midnight and the configured morning time is later on the clock, `morningBriefSlotMin` wraps `afterWake` modulo 1440 before comparing it with `floor`, so it selects the configured time even when that time is before the user's typical wake. The briefing is scheduled before the user wakes.

Compare wake-plus-30 and the configured floor as date-aware times so a midnight wrap does not make an earlier time appear to follow wake.

Also at `lib/ai/reminder_plan.dart:66`.

+    }
     return slotMin > nowMin;
</code_context>
<issue_to_address>
**Wrapped slots miss or misplace briefings**

When the morning slot wraps across midnight and a scheduling pass runs before the next-day slot or shortly after midnight, `aiSlotArmable` compares minute-of-day values without accounting for the slot's date, so it either treats the next-day slot as already past or treats a late-evening slot as armable after midnight. `morningBriefLateFire` then returns null for the latter case and `nextDailyInstant` schedules tomorrow's briefing using today's readiness.

Determine armability and the next occurrence using date-aware instants rather than minute-of-day comparisons across midnight.

+    final now = DateTime.now();
+    final today = todayLabel(now);
+    final nowMin = now.hour * 60 + now.minute;
</code_context>
<issue_to_address>
**Briefings use a stale slot time**

When asynchronous lookups or scheduling work cross the morning slot boundary, `aiSlotArmable` and `nextDailyInstant` use different clock readings, so a slot can pass the armability check and then be resolved as tomorrow's occurrence. The user gets a briefing scheduled with today's readiness before tomorrow's data has been checked.

Use one current time, captured after the asynchronous lookups, consistently for armability and resolving the scheduled occurrence.

<code_context>
+    final announcedKey = '$morningBriefAnnouncedPrefix$today';
</code_context>
<issue_to_address>
**Fired-key storage grows indefinitely**

When morning briefing guards are recorded across successive days, `FiredKeyStore` and the database pruners only recognize dates at the start of a key, but the announced and slot keys put the date after a text prefix. Neither store prunes these keys, so persistent fired-key state grows over time.

Format the announced and slot keys with the date at the beginning so both stores can prune them.

Also at `lib/notify/notification_center.dart:935-936`.
</issue_to_address>

### Comment 10

+      // Delivery is read off the PREVIOUSLY armed occurrence, not the new plan
+      // slot: announced + no longer pending means it already fired — that guard
</code_context>
<issue_to_address>
**Old slot key preserves wrong time**

When the user changes the morning time from one value to another and then back to the original value on the same day, `slotArmed` can remain true for a slot that was cancelled earlier that day. If the user changes the time from A to B and back to A, this condition treats B's pending notification as the matching A occurrence and preserves it, so the briefing remains scheduled for B instead of the selected time.

Track the currently pending slot rather than whether a slot was ever armed that day, or release the old slot key when cancelling its pending registration.
</issue_to_address>

Sourcery assessment

Needs a human reviewer. 10 findings to address first, and if the readiness or wake-time calculation is wrong, the scheduler can send the briefing at an inappropriate time or omit it when it should have been armed. Reverting restores future scheduling behavior, but a notification already delivered cannot be recalled.

Blocking findings: lib/state/app_state.dart:3330, lib/state/app_state.dart:3401, lib/state/app_state.dart:3401, lib/notify/notification_service.dart:675, lib/notify/notification_center.dart:1027, and 5 more

Do not wrap the wake minimum into an earlier occurrence.

With typicalWakeMinOfDay = 1425 (23:45) and morningMin = 480, this calculation returns 08:00. With quiet hours disabled, the scheduler can arm 08:00 today, before the supplied wake time.

Keep the day offset when adding 30 minutes. If the required time falls tomorrow, omit today’s slot instead of reducing it modulo 1440.

Read the clock after the last await and derive the morning occurrence from it.

now and nowMin are captured before the state reads and cancels. The clock can cross the 08:00 boundary before the loop runs. aiSlotArmable then accepts the slot with the stale minute. nextDailyInstant reads a fresh clock and returns tomorrow. morningBriefLateFire receives the stale now and returns null, so today's catch-up is skipped and tomorrow's briefing is armed without tomorrow's data.

Refresh the clock after the last await, and build the morning occurrence from that same instant.

Suggested fix

-    final now = DateTime.now();
+    var now = DateTime.now();
     final today = todayLabel(now);
-    final nowMin = now.hour * 60 + now.minute;
+    var nowMin = now.hour * 60 + now.minute;

     await svc.cancel(NotificationService.idEveningBrief);
     await svc.cancel(NotificationService.idJournalLog);
+    // Read the clock after the last await so the armable check, the late-fire
+    // window and the morning occurrence use one instant.
+    now = DateTime.now();
+    nowMin = now.hour * 60 + now.minute;
     if (plan.isEmpty) return;

       var at = svc.nextDailyInstant(s.hour, s.minute);
       if (s.id == NotificationService.idMorningBrief) {
+        // nextDailyInstant reads its own clock; build today's occurrence from `now`.

Keep an unknown pending state distinct from an empty queue.

If this query fails after a morning registration, the caller treats the empty result as delivered. If the user disables the reminder, NotificationCenter cancels it but retains announcedKey because hasPendingMorning is false. Re-enabling then preserves a nonexistent registration and suppresses the briefing for the day (lib/notify/notification_center.dart, Lines 1027–1037).

Return an explicit unknown result, or propagate the error and stop reconciliation before cancellation. Retry the pending query on the next pass.

Major · Re-run the reminder pass after derivation settles the crossday row. · app_state.dart:2975

lib/state/app_state.dart:2975
Major · Functional Correctness · Quick win

Re-run the reminder pass after derivation settles the crossday row.

The stored-data path calls _ensureRemindersScheduled() before derivation finishes. While today's crossday row is unsettled, the readiness check returns false, so the morning briefing is not armed. When derivation completes, afterDrain() does not run the reminder pass again. The briefing then stays unarmed until a later stored-data callback or foreground pass runs the check.

Call the reminder pass from the derivation completion path. The pass is serialized, so the extra call is safe.

Suggested fix

In lib/state/derive_coordinator.dart, add a callback and call it after the recovery notification:

   required Future<void> Function() maybeNotifyRecoveryReady,
+  required Future<void> Function() refreshAiReminders,

         _maybeNotifyRecoveryReady = maybeNotifyRecoveryReady,
+        _refreshAiReminders = refreshAiReminders,

   final Future<void> Function() _maybeNotifyRecoveryReady;
+  final Future<void> Function() _refreshAiReminders;

       unawaited(_maybeNotifyRecoveryReady());
+      unawaited(_refreshAiReminders());

In lib/state/app_state.dart, pass the existing pass to the coordinator next to maybeNotifyRecoveryReady:

     maybeNotifyRecoveryReady: _maybeNotifyRecoveryReady,
+    refreshAiReminders: _ensureRemindersScheduled,

Tests that construct DeriveCoordinator must supply the new callback.

Defer replacement when pending status is unknown.

If today's 08:00 briefing has fired, changing its time to 09:00 at 08:15 should not announce it again. If pendingIds() fails, hasPendingMorning becomes true. The new slot has no recorded key, so this branch releases announcedKey after a successful cancellation and schedules another briefing.

Cancellation success does not establish that the notification was undelivered. The declared plugin version's Android implementation returns success after cancelling without checking delivery. (raw.githubusercontent.com)

When morningAnnounced is true and pendingKnown is false, defer replacement. Guard both the release and the subsequent scheduling; guarding only the release still permits another alert.

Use catchError on the future chain.

Dart Future has no .catch(...) method. This expression prevents the application from compiling. Replace it with pass.catchError((Object _) {}) so a failed pass does not block subsequent passes.

Use a typical wake time, not the recommended wake time.

crossday_pipeline.dart, Lines 541–555, produces this value with ana.recommendedWake from recommended bedtime, sleep need, and efficiency. That recommendation can differ from the user's typical observed wake time. The briefing can therefore be scheduled before the typical wake time or unnecessarily delayed. Read the observed typical wake time instead.

Unverified finding
Verification ran but could not confirm this finding. It is shown for review, not as a verified issue.

Do not treat the first sample after midnight as a completed night.

If the latest crossday row is still yesterday's row, a band sample from 00:15 passes this check even if the user is still asleep. The scheduler can then arm the morning briefing from a partial night. Require evidence that the overnight has settled before accepting the sample.
