_restaurarVolumenMediaUnaVez() read the BuildContext to reach the
alarm port, but dispose() runs after the element is defunct, so the
lookup always threw (caught and logged) and the dispose safety-net
never actually restored the media volume when it was the sole exit
path. The state is now captured once in initState and the restore
helper uses the field. Adds the missing dispose-as-sole-caller
regression test.
The native service and the Flutter player each ran their own 5%-to-
target fade-in, and both could drive audible volume at the handoff,
producing a jump or ramp reset. The Dart ramp now starts exactly once
from the handoff-confirmation path: the player still pre-starts at 5%,
and _confirmarAudioFlutterListo() starts the ramp in a finally block
so it runs whether the native confirmation succeeds or fails — the
alarm can never stay stuck at 5% if the native side is already gone.
Work unit 3/3 of alarm-volume-ramp-restore (fade-in dedup).
- 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)
