Verify Report: Pre-notice Live Countdown
Change: pre-notice-live-countdown Mode: Kotlin-only, code-inspection verification (no Kotlin test harness in repo; Strict TDD applies to Dart/Flutter only and does not govern this change) Verdict: PASS WITH WARNINGS
Completeness (tasks.md cross-check)
| Section | Status | Notes |
|---|---|---|
| 1. AlarmScheduler.kt core tick engine (1.1-1.4) | DONE | Both functions present, public, correct formula |
| 2. Wire 3 scheduler-side cancel sites (2.1-2.4) | DONE | All 3 confirmed by line inspection |
| 3. Receiver re-arm + ceil + 2 cancel sites (3.1-3.5) | DONE | Single remaining-compute reused for text+arm |
| 4. Full 5-site cross-check (4.1) | DONE | grep confirms exactly 6 matches |
| 5. Manual/device QA (5.1-5.5) | NOT RUN | Explicitly out of apply scope, flagged below, not a CRITICAL blocker for this SDD cycle |
Build/Analysis Evidence
- flutter analyze: No issues found! (ran in 2.5s). Zero issues, confirms no Dart-side regression from this Kotlin-only change.
- flutter build was correctly NOT run (per project instructions).
- git status / git diff --stat: only AlarmScheduler.kt (+70/-2) and PluriWaveAlarmReceiver.kt (+21/-3) modified. 91 lines total, matches tasks forecast (about 90-130) and the 400-line budget (Low risk, confirmed accurate). No Dart/ARB/l10n files touched, confirming the design's Kotlin-only claim.
- grep -rn cancelPreNoticeCountdown across both files: exactly 6 matches (1 declaration AlarmScheduler.kt:531 + 5 call sites AlarmScheduler.kt:93,143,631 and PluriWaveAlarmReceiver.kt:59,80). Matches the design/tasks claim exactly.
- grep -n requestCode(id, 9): both occurrences (AlarmScheduler.kt:498 arm, :534 cancel) live exclusively in AlarmScheduler.kt, never in the receiver. Confirms both resolve through AlarmScheduler.requestCode = 31hash+slot (L934), never the receiver's separate 47hash+slot (L244). This is the design's single highest-risk correctness gate and it is verifiably satisfied.
Spec Compliance Matrix (8 requirements / 16 scenarios)
| # | Requirement | Scenario | Status | Evidence |
|---|---|---|---|---|
| 1 | First Pre-Notice Post | First post at T-30min | PASS | schedulePreNotice unchanged (L139-191), fires ACTION_PRE_NOTICE via setExactAndAllowWhileIdle at T-30min |
| 2 | Per-Minute Tick Re-Arm | Tick re-arms next minute | PASS | armNextPreNoticeCountdownTick L484-519: reuses ACTION_PRE_NOTICE (L500), nextBoundary = triggerAtMillis-(remaining-1)*60000 (L495), slot 9 (L498) |
| 2 | Per-Minute Tick Re-Arm | Tick updates notification content | PASS | Same notificationIdForAlarm(alarmId) (receiver L197) + FLAG_UPDATE_CURRENT (L155). Update in place, no duplicate |
| 3 | Self-Healing Minute Computation | Normal tick sequence | PASS | computeRemainingMinutes (receiver L224-225) recomputes from wall clock each call via ceil formula, no stored counter |
| 3 | Self-Healing Minute Computation | Missed tick self-heals by jumping | PASS by construction | Same recompute-from-wall-clock design as snooze-countdown (shipped pattern); UNTESTED at runtime, Doze behavior requires device (Task 5.4, not run) |
| 4 | Self-Stop at Final Minute | Chain stops before final minute | PASS | armNextPreNoticeCountdownTick L494: if remaining less-equal 1L return before arming |
| 5 | Consistent Rounding via ceilMinutes | Rounding matches snooze countdown | PASS | Receiver L224-225 formula identical to AlarmScheduler.ceilMinutes L620-621 |
| 6 | Tick Chain Cancellation | Full alarm cancellation tears down chain | PASS | cancelAlarm L631 calls cancelPreNoticeCountdown(id) |
| 6 | Tick Chain Cancellation | No-next-trigger reschedule cancels chain | PASS | scheduleSpec L93 |
| 6 | Tick Chain Cancellation | Snooze transition cancels chain | PASS | schedulePreNotice L143 |
| 6 | Tick Chain Cancellation | Skip-next cancels chain | PASS | Receiver L80, BEFORE skipNext (L81). Correct ordering |
| 6 | Tick Chain Cancellation | Postpone-next cancels chain | PASS | Receiver L59, BEFORE postponeNext (L60). Correct ordering |
| 7 | Notification ID Reuse / Mutual Exclusivity | Pre-notice and snooze-countdown never concurrent | PASS | scheduleSpec L123-135 branches exclusively on snoozeUntilMillis not null |
| 7 | Notification ID Reuse / Mutual Exclusivity | Notification updates in place | PASS | Shared notificationIdForAlarm(id), FLAG_UPDATE_CURRENT semantics |
14/14 statically-verifiable scenarios PASS. 2 scenarios (Doze-delayed jump, and device-level confirmation of in-place notification updates) are PASS-by-construction/code-inspection only; true runtime confirmation requires the not-yet-run manual QA in tasks.md section 5.
Design Coherence
| Design Decision | Code Match |
|---|---|
| Reuse ACTION_PRE_NOTICE, no new action constant | Confirmed, no new ACTION_PRE_NOTICE_COUNTDOWN style constant added |
| Slot 9 via AlarmScheduler.requestCode (31*hash+slot) | Confirmed, both arm and cancel |
| armNextPreNoticeCountdownTick and cancelPreNoticeCountdown both public | Confirmed, no private modifier, declared with bare fun |
| Arm/cancel ownership both in AlarmScheduler | Confirmed |
| Receiver computes remaining once, reuses for text + arm call | Confirmed (L143, then passed to armNextPreNoticeCountdownTick at L214 without re-reading the clock) |
| Kotlin-only change, no Dart/ARB changes | Confirmed via git status |
One documented deviation from reuse ceilMinutes() as literally read: the design resolution says the receiver duplicates the formula rather than calling into AlarmScheduler.ceilMinutes() (class-private), because promoting it to shared/public surface was explicitly rejected to avoid scope creep. tasks.md 3.2 documents this tradeoff and the implementation matches it exactly (formula duplicated, not shared). Not a deviation from what was actually decided, flagged as SUGGESTION only.
Issues
CRITICAL: None.
WARNING:
- Manual/device QA (tasks.md section 5.1-5.5) has not been executed. This covers: happy-path 29-to-1 countdown on a real/emulated device, self-stop confirmation at final minute, skip/postpone/snooze-transition teardown via adb dumpsys alarm, Doze-delayed jump behavior, and snooze-countdown regression check. This was explicitly out of scope for the apply phase per the tasks artifact, but it is a real gap before this change can be considered fully done. Recommend running it before/shortly after merge, not blocking the SDD cycle itself.
SUGGESTION:
- ceilMinutes formula is duplicated (once in AlarmScheduler as a private function, once inline in PluriWaveAlarmReceiver.computeRemainingMinutes). This was a deliberate, documented tradeoff in the design/tasks to avoid widening AlarmScheduler's public surface. Low risk since both formulas are simple one-liners and now textually identical, but a future change to one without the other would silently desync rounding behavior between pre-notice and snooze-countdown. Consider a tiny shared top-level internal fun ceilMinutes(deltaMillis: Long): Long if a third consumer ever appears.
Final Verdict
PASS WITH WARNINGS. All 4 in-scope implementation/code-inspection sections (1-4) are complete and correct. The critical correctness gate (slot 9 via the same AlarmScheduler.requestCode formula for both arm and cancel) is verifiably satisfied by direct code inspection; this was the design's top identified risk and it does not manifest. flutter analyze is clean. Diff scope matches the forecast exactly (Kotlin-only, 91 lines). The only open item is manual device QA (section 5), which was always out of scope for the automated apply/verify cycle and should be tracked as a follow-up, not treated as blocking archive.
