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.

Alarm Stop Safety Specification
Purpose
Dart-side fail-safe orchestration: every surface that can act on a ringing alarm (ringing-screen Stop/Snooze, alarm-list disable/toggle, edit/save, delete) MUST deterministically silence a live ring or surface a visible, retryable failure. Dismiss-by-design (the ringing screen always closes) is preserved but MUST NOT mask a failed native stop.
Requirements
Requirement: Mutation-While-Ringing Stop Guard
EstadoAlarmas MUST route any mutation targeting the currently-ringing alarm — disable/toggle (cambiarActiva), edit/save (guardarAlarma), delete (eliminarAlarma) — through one centralized stop-first guard, not per-call-site logic.
Scenario: Toggling the ringing alarm off stops audio
Testability: [dart-testable]
- GIVEN alarm X is ringing and active
- WHEN
cambiarActiva(X, false)is called - THEN
detenerSonidoNativo(X)runs before/alongsideprogramar/cancelar
Scenario: Editing/saving the ringing alarm stops audio
Testability: [dart-testable]
- GIVEN alarm X is ringing
- WHEN
guardarAlarmais called with an edited config for id X - THEN the stop guard fires before the save persists
Scenario: Deleting the ringing alarm stops audio (regression lock)
Testability: [dart-testable]
- GIVEN alarm X is ringing
- WHEN
eliminarAlarma(X)is called - THEN
detenerSonidoNativo(X)runs beforecancelar(locks in existing correct behavior)
Scenario: Mutating a non-ringing alarm does not trigger the guard
Testability: [dart-testable]
- GIVEN alarm Y is ringing, alarm Z is not
- WHEN
cambiarActiva(Z, ...)orguardarAlarma(Z)is called - THEN no stop call targets Y
Requirement: Stop/Snooze Result Verification
Stop (detenerSonidoNativo) and snooze channel calls MUST return a success/failure/unconfirmed result instead of only throwing or being swallowed. EstadoAlarmas MUST record this outcome per alarm.
Scenario: Native stop confirms success
Testability: [dart-testable]
- GIVEN the stop channel call resolves with
confirmed=true - WHEN
_detener()completes - THEN
EstadoAlarmasrecords a confirmed-stop state for that alarm
Scenario: Native stop reports unconfirmed/failure
Testability: [dart-testable]
- GIVEN the fake channel is set to fail or return
confirmed=false - WHEN
_detener()/_posponer()runs - THEN
EstadoAlarmasrecords a failed/unconfirmed state, never a confirmed one
Requirement: Retryable Force-Stop Affordance
When a stop/snooze attempt is not confirmed, the app MUST present a persistent, retryable "Force stop" affordance until a confirmed stop is recorded or the alarm is externally cleared. Dismiss-by-design (screen closing) stays independent of this affordance.
Scenario: Failed stop surfaces Force stop
Testability: [dart-testable]
- GIVEN
_detener()receives an unconfirmed/failure result - WHEN the ringing screen finishes its dismiss-by-design close
- THEN a persistent retryable Force-stop affordance appears
Scenario: Retrying force-stop attempts stop again
Testability: [dart-testable]
- GIVEN a Force-stop affordance is visible after a failed attempt
- WHEN the user retries
- THEN
detenerSonidoNativois invoked again; success clears the affordance, failure keeps it visible
Scenario: Confirmed stop shows no failure UI
Testability: [dart-testable]
- GIVEN a confirmed-stop result
- WHEN the screen dismisses
- THEN no Force-stop affordance appears
Requirement: Notification Stop/Snooze Stays Native-Only
Notification Stop/Snooze actions use PendingIntent.getService directly (native-only, Flutter-independent) and remain outside this Dart guard's scope; only Dart-initiated mutations and in-app screens are covered here.
Scenario: Notification action bypasses the Dart guard by design
Testability: [kotlin-static]
- GIVEN a fire notification with Stop/Snooze actions
- WHEN the user taps either action
- THEN it invokes the native service directly, never touching
EstadoAlarmas' guard
