Root-cause fix for the unstoppable-alarm incident (alarm rang 15 minutes,
only uninstall silenced it) plus systematic hardening of every stop path.
Native (Kotlin):
- Verified stop: stopActiveAlarm now derives its result from the real
post-teardown state (companion instance + synchronous stopEverything +
activeRingingId check) instead of reporting unconditional success.
- Atomic teardown: every stop path (stop action, notification button,
snooze, missed, onDestroy, startForeground failure) funnels through one
stopEverything() covering audio, wakelock, notification, foreground
state and firing-record cleanup; player.release() guarded.
- Bounded ringing: 10-minute auto-silence armed via AlarmManager fires a
FIRED->MISSED transition with a localized missed-alarm notification;
repeating alarms keep their native rearm, deleted alarms never produce
ghost MISSED notifications.
- Durable firing record with onStartCommand re-validation (resurrection
guard) and boot-time stale cleanup; firing records cleared on every
refuse/mismatch/cancel path.
- New notification-only dismissal channel (dismissAlarmNotificationOnly)
so UI-level dedup can never kill a live ring's audio.
Flutter (Dart):
- Stop/disable/edit/delete of a ringing alarm always attempt to silence
it; on native-query failure the stop falls back toward silence via the
id-scoped legacy stop.
- Verified-stop results surface failures: the ringing screen keeps
dismiss-by-design on success, but on a verified failure it stays up
with a persistent force-stop banner (guarded against double-dismiss)
and auto-dismisses if the ring ends externally (missed/notification).
- Missed events sync alarm bookkeeping without opening the ringing UI.
- 4 new l10n keys translated across all 13 locales (ARB guard green).
550 tests green, analyzer clean. Reviewed in 3 adversarial 4-lens rounds
(2 deterministic + 1 refuter-corroborated critical fixed); formal
gentle-ai receipt waived by maintainer authorization (correction scope
legitimately exceeded the frozen genesis paths). On-device QA checklist
in openspec/changes/alarm-system-overhaul/tasks.md pending before
archive.
posponerAlarma anchored the snooze to snoozeOrigen ?? proximaEjecucion,
but once the native fire path works, the fire-time sync records the
handled occurrence and recalculation advances proximaEjecucion to the
NEXT day before the user can even tap snooze on the still-ringing
screen. "Posponer 3" therefore armed the snooze a full day out
(captured on-device: snoozeCountdown remaining=1443 minutes). The bug
was invisible before because the broken delivery path never advanced
proximaEjecucion while ringing — each fix unmasked the next.
The anchor is now the newest occurrence that is not meaningfully in
the future (shared 90s imminence window): snoozeOrigen for re-snoozes,
proximaEjecucion on the watchdog path where it is still today's
just-due occurrence, ultimaEjecucionGestionada on the native-fire path
where the sync recorded the ringing occurrence, then now. ServicioAlarmas
exposes ahora() so the anchor uses the same injectable clock as the
rest of the scheduling math. Test fixtures that snoozed half an hour
before the ring — a state the ringing screen can never be in, since it
is posponerAlarma's only production caller — now move the clock to
ring time, preserving their original expectations.
posponerAlarma() and posponerProximaDesdePreaviso() called the native
scheduler with no error handling, unlike guardarAlarma(). When the
native call failed (e.g. revoked exact-alarm permission), the
exception escaped before notifyListeners() ran, leaving the alarm
list stuck on stale data with no real alarm scheduled and no snooze
countdown notification.
Both methods now mirror guardarAlarma()'s pattern: permission
pre-check, try/catch into _error, and an unconditional
notifyListeners() so the UI always reflects the outcome. Failures
surface via SnackBar in the ringing screen and in app.dart's
postpone-next handler.
The snooze button was fire-and-forget without error handling: if
posponerAlarma threw (e.g. native scheduleAlarm returns false on a
device without exact-alarm permission), _dismissScreen never ran. The
stuck modal also kept _alarmaSonandoActiva true, which made the next
ring get ignored. _posponer/_detener now dismiss in a finally and stop
audio defensively.
Add a native, AlarmManager-driven snooze countdown notification that
re-posts every minute ("Rings in N min", 3->2->1) while the engine is
dead. scheduleSpec drives scheduleSnoozeCountdown for snoozes (instead
of the 30-min pre-notice). Localized text and button labels travel
Dart->Kotlin as {minutes} templates, same pattern as preNoticeTemplate.
Notification actions: "snooze again" (snoozeAgain, anchored to now)
reports back via the existing snoozed event; "stop" (cancelSnooze)
records a handled occurrence for cold-start reconciliation and emits a
new snoozeCancelled event handled in EstadoAlarmas.
Adds snoozeCountdown/snoozeAgainAction keys across all 13 locales and a
test for the snoozeCancelled event. Kotlin changes are static-reviewed
only; no Android build environment available here.
- Integrate audio_session (new servicio_audio_session.dart): incoming calls pause the radio and resume on end, headphone unplug pauses without auto-resume, permanent focus loss never auto-resumes, duck lowers volume
- Add play-intent flag to ServicioAudio so interruption handling and future reconnect logic can distinguish user pause from system-driven stops
- Eliminate read-modify-write race in ServicioAlarmas with an in-memory cache and single-writer queue across all mutations; recalcularTodas persists only when state actually changed
- Convert ServicioAlarmasAndroid static StreamController/handler to injectable instance fields, restoring test isolation
- Inject a single cached SharedPreferences from main.dart across services and state (removes 23 inline getInstance() calls)
- Move configurarLocalizaciones out of MiniReproductor.build() (was running on every rebuild during playback)
- Bound the alarm fire-dedup set (cap 200 entries, 24h pruning)
- 12 new tests (89 total green), flutter analyze clean
- Use mediaPlayback|systemExempted FGS type with FOREGROUND_SERVICE_SYSTEM_EXEMPTED so alarms fire on Android 14+ (FOREGROUND_SERVICE_ALARM does not exist in the SDK)
- Deduplicate fire notifications: the foreground service FSI notification is the single owner; receiver path removed
- Notification channel v2 with alarm sound URI and USAGE_ALARM attributes, one-time guarded migration from legacy channels
- Pass fallback station through the MethodChannel (NativeAlarmSpec schemaVersion 3) with a three-stage audio chain: primary -> fallback station -> bundled WAV
- Native fade-in volume ramp honoring fadeInSegundos when the app is killed
- Request battery-optimization exemption once, tracked with a persisted asked-once flag
- Fix snooze end-to-end: native ACTION_SNOOZE now reports back to Flutter (snoozed event + cold-start sync), snooze anchor unified to occurrence+minutes on both sides, periodic recalc no longer erases an active snooze
- Add snooze buttons (3/5/10/custom) to the ringing screen with shared audio teardown
- Redesign ringing screen on PluriWaveScaffold with reduced-motion-aware entry animation (new PluriAnimate helper)
- Alarm editor: live next-trigger preview, searchable station pickers (primary and fallback), configurable snooze duration, volume floor down to 0
- New alarm strings localized across all 13 locales
- New unit/widget tests for the snooze flow, alarm bridge payloads, ringing screen and editor (77 tests green)
- SDD artifacts for the app-quality-and-native-alarms change (explore, proposal, spec, design, tasks, apply progress)
