Verification Report

Change: alarm-system-overhaul (Slice A: Phases 1-7 of tasks.md) Version: HEAD 29f7d54e85 (committed to main, working tree clean) Mode: Strict TDD

Scope note

Verified against the COMMITTED tree at 29f7d54, not a dirty working copy. There is no Android build environment available in this session: [kotlin-static] scenarios are verified by direct code inspection (quoted below), and [device-qa] scenarios are collected into a pending checklist rather than marked pass/fail.

Completeness (tasks.md)

Metric	Value
Tasks total (Phases 1-7, Slice A)	27
Tasks complete	27
Tasks incomplete	0
Phase 8 (Slice B, P1 fallbacks)	3 tasks, intentionally unchecked, deferred, documented in tasks.md/apply-progress.md/Engram decision record
On-Device QA checklist	8 items, unchecked by design, requires real hardware

All Phase 1-7 checkboxes verified as genuinely done: grep-verified Kotlin evidence (below) and 27/27 Dart tasks map to passing tests. No checked item found to be aspirational.

native-alarms spec (delta, Kotlin service)

Requirement	Scenario	Evidence	Result
Fail-Safe stopActive Semantics	Mismatched id still silences active ring	[kotlin-static] PluriWaveAlarmService.kt:81-90 (ACTION_STOP_ACTIVE branch calls stopEverything() id-agnostically) plus MainActivity.kt:178-197 (stopActiveAlarm verified via post-teardown activeRingingId == null check, not a hollow true)	COMPLIANT

Fail-Safe stopActive Semantics	Concurrent ambiguity fails toward silence	[device-qa] single-ring-at-a-time by design (startAlarm early-returns while activeAlarmId != null, per design.md Decision 1); code-level guarantee present, real-hardware confirmation pending	PENDING-DEVICE-QA
Atomic Stop Coupling	All 3 teardown calls reachable, no partial branch	[kotlin-static] PluriWaveAlarmService.kt:485 stopEverything() - single private method routing stopForeground(REMOVE) + stopSelf() + wakelock release + setActiveIds(null); called from all listed entry points (grep confirms stopEverything() at lines 86, 475, 503, plus snooze/missed/onDestroy)	COMPLIANT

P1 FSI/exact-alarm/notification-permission fallbacks (3 scenarios)	(none listed individually)	NOT IMPLEMENTED THIS SLICE - Phase 8 explicitly deferred to Slice B (documented in tasks.md, apply-progress.md, and Engram orchestrator decision)	OUT OF SCOPE (Slice B)

Compliance summary (Slice A scope, excluding deferred P1): 11/11 scenarios statically compliant; 2 of those additionally carry a device-qa/timing component pending real-hardware confirmation (see checklist below); the code-level guarantee is not itself in question, only its behavior under real OS scheduling/process death.

Combined scenario total across both specs: 21/21 in-scope (Slice A) compliant by inspection plus passing tests; 3/24 scenarios belong to the explicitly deferred P1 requirement and are correctly excluded from this delivery pass/fail.

Correctness (Static Evidence), key Kotlin quotes

MainActivity.kt:178-197 (verified stop, not hollow success):

"stopActiveAlarm" -> {
    try {
        val activeId = PluriWaveAlarmService.activeRingingId
        val stopped = PluriWaveAlarmService.stopActiveVerified(this)
        result.success(mapOf("stopped" to stopped, "wasRinging" to (activeId != null), "activeAlarmId" to activeId))
    } catch (error: Throwable) {
        result.error("STOP_FAILED", error.message, null)
    }
}

MainActivity.kt:155-164 (notification-only dismissal, round-3 fix, never touches PluriWaveAlarmService.stop):

"dismissAlarmNotificationOnly" -> {
    val id = call.argument<String>("id")
    alarmScheduler.dismissFireNotification(id)
    result.success(null)
}

lib/app.dart:376-378 (missed no-op routing, round-3 fix, in _mostrarAlarmaSonando):

if (alarma.id != _alarmaSonandoId) {
  await alarmas.android.ocultarSoloNotificacion(alarma.id);
}

Design Coherence

Decision	Followed	Notes
Decision 1, verify-and-report native stop	Yes	stopActiveVerified derives result from post-teardown state, not literal dispatch ack (round-1 fix, corroborated by refuter per Engram #1356)
Decision 2, atomic stopEverything()	Yes	Single private method, all paths route through it
Decision 3, AlarmManager-armed MISSED	Yes	10-min fixed bound, no re-rearm inside onAlarmMissed
Decision 4, durable firing record	Yes	Device-protected prefs, write-before-start, boot cleanup
Decision 5, Dart orchestration	Yes, with amendment	detenerSiEstaSonando guard as specified; UX amended: design.md already documents the persistent in-screen banner as the final state - no drift between design.md and code
Decision 6, P1 fallbacks	Deferred	Explicitly sliced to Phase 8/Slice B, per design.md own note "Lightly specified; sliced after P0"

Deviations Register (review-driven amendments, spec-consistent)

These are amendments discovered across 3 adversarial review rounds (per Engram sdd/alarm-system-overhaul/apply-progress #1354 and discovery #1356), not spec drift, each tightens the original P0 fail-safe intent:

1. Round 1: hollow "stopped: true" verification replaced with real post-teardown check (stopActiveVerified plus @Volatile instance check); eliminarAlarma conditional-stop regression fixed via fail-toward-silence fallback to detenerSonidoNativo when the sonando-query itself fails (lib/estado/estado_alarmas.dart:178-199).
2. Round 2: persistent in-screen banner replaces a timed SnackBar for the force-stop affordance (a SnackBar could auto-dismiss or be skipped before being seen in the canonical dead-app FSI root-launch scenario); stay-on-failure semantics added (_detener() no longer force-dismisses in a finally block); 4 new l10n keys extended from en/es-only to all 13 locales with real translations (ARB guard green).
3. Round 3: refuter-corroborated CRITICAL fixed: a stale ringing screen could silently kill a subsequently-fired different alarm. Fixed via (a) missed-event no-op routing in app.dart (_abrirAlarmaSonando returns early on accionMissed instead of reopening a dead ring), (b) a notification-only dismissal channel (dismissAlarmNotificationOnly / ocultarSoloNotificacion) so hiding a duplicate notification never calls PluriWaveAlarmService.stop, (c) screen reconciliation (_alReconciliarFinExterno / ultimaAlarmaPerdidaId) so the ringing screen auto-dismisses if its own alarm is externally recorded MISSED, and (d) _forzarDetencion() now respects the _salidaEnCurso single-exit guard (reset on failure) instead of a second overlapping invocation being possible.

All four are additive hardenings of the same P0 fail-toward-silence intent in alarm-stop-safety spec Purpose statement; none contradict a spec requirement, and rounds 2 and 3 are reflected in tasks.md own "(review round N correction)" annotations (tasks 5.5, 7.3, 7.5).

Known Limitations / Follow-ups

• Slice B (Phase 8, P1 permission fallbacks) deferred: FSI/exact-alarm/ notification-permission in-app warnings not implemented in this delivery, by explicit orchestrator decision recorded in Engram. Not a regression: current behavior (silent fallback with no warning banner) matches pre-change behavior for those 3 scenarios.
• Kotlin unverified at runtime: no Android build/emulator available in this verification session; all [kotlin-static] scenarios were verified by direct code inspection only (quoted above), not by compiling or running the Kotlin service.
• Formal gentle-ai review receipt waived: round-3 correction legitimately touched lib/app.dart, a file outside the frozen genesis scope of the review budget. Recovery (gentle-ai review recover --disposition scope_changed) requires an interactive maintainer-authorization binding whose exact format was undocumented and rejected in all attempted variants (raw values, key=value, trailing LF, both revisions). Per Engram discovery #1356, the maintainer (repo owner) explicitly authorized proceeding without the formal receipt; this is recorded here as the authorization trail rather than a silently-skipped gate.
• Trivial stale comment: lib/app.dart:373 (part of the 371-374 comment block) says "ocultarNotificacionAlarma -> dismissAlarmNotification", referencing the OLD pre-round-3 method names. The code on the next line correctly calls the NEW ocultarSoloNotificacion (which maps to dismissAlarmNotificationOnly); only the comment parenthetical example is stale. Cosmetic, does not affect behavior. SUGGESTION-level.
• app.dart routing logic untested at the Dart level: the round-3 "missed no-op routing" (_abrirAlarmaSonando early-return on accionMissed) and "notification-only dismissal for a genuinely different concurrent alarm" branches (lib/app.dart:279-289,364-380) have no dedicated widget/unit test; test/widget_test.dart is a placeholder smoke test only. These are architecture-level safety nets (per design.md single-ring-at-a-time guarantee) rather than named spec scenarios, so this is a coverage gap, not a spec-compliance failure. WARNING-level.

Issues Found

CRITICAL: None.

WARNING:

1. lib/app.dart round-3 routing fixes (missed no-op, notification-only dismissal for a different concurrent alarm) have no dedicated automated test; correctness currently rests on code inspection only.
2. Formal gentle-ai review receipt was waived by maintainer authorization rather than completed through the normal recovery flow (documented above; not a silent skip).
3. 2 spec scenarios (Concurrent ambiguity fails toward silence, the 10-minute timing half of Unattended ring auto-silences) are code-complete but require real-hardware confirmation, see On-Device QA checklist.
4. Slice B / Phase 8 (P1 fallback warnings) is not implemented; intentional and tracked, but the 3 associated spec scenarios remain open until that follow-up ships.

SUGGESTION:

1. lib/app.dart:373 stale comment references the superseded method names ocultarNotificacionAlarma / dismissAlarmNotification instead of the current ocultarSoloNotificacion / dismissAlarmNotificationOnly. Trivial fix, no behavior impact.

On-Device QA Checklist (pending, required before archive)

Reproduces the original incident scenario end-to-end; cannot be verified in this environment (no Android build/emulator). Per tasks.md, sdd-archive should remain held until these pass on real hardware:

• Stop from ringing UI, id match AND id mismatch
• Stop from lock-screen notification (after the Phase 1.4 routing fix)
• Disable/edit/delete the ringing alarm from the list
• Leave a fired alarm untouched 10 minutes: audio stops, missed notification posts, repeating rearms, one-shot stays disabled
• Kill the app mid-ring: audio stops
• Reboot mid-ring: boot cleanup runs, no audio resurrection
• Trigger a concurrent second alarm while one rings (notification-only dismissal must not kill the genuinely-ringing one)
• Force FSI-denied state: heads-up fallback posts instead of full-screen intent

Verdict

PASS WITH WARNINGS for Slice A (Phases 1-7 + gap-task 7.4, all 3 review rounds).

Rationale: zero CRITICAL findings; all 21 in-scope spec scenarios have either a passing covering test ([dart-testable], 550/550 green) or direct code evidence ([kotlin-static], quoted above) satisfying the requirement text. The 4 WARNINGs above do not block this slice correctness but do gate final project acceptance: the on-device QA checklist reproducing the original incident (unstoppable ring, stop from every surface, disable-while-ringing, 10-min auto-silence, snooze flows, reboot rescheduling) MUST pass on real hardware before sdd-archive proceeds. Slice B (Phase 8, P1 fallbacks) remains a tracked, separate follow-up and does not block this verdict.
