- New EstadoGrabacion owns the recording service, subscription, directory/size preferences and open-file actions
- New EstadoBusqueda owns search, nearby stations, pagination and the min-bitrate filter
- New orden_emisoras.dart with the OrdenEmisoras enum, shared sorter and list identity memoization so context.select comparisons work on derived lists
- Large screens (inicio, buscar, favoritos, ajustes, reproductor) consume scoped selects/dedicated notifiers instead of root context.watch<EstadoRadio>, so audio buffer events no longer rebuild whole screens
- Remove all 15 TODO(S4b) compat members from EstadoRadio; consumers use the dedicated providers. EstadoRadio drops from ~1121 to 753 lines, keeping playback/stations/favorites orchestration
- 8 new tests including a rebuild-scoping probe (110 total green), flutter analyze clean
- New ServicioExportImport owns the v2 backup envelope, pretty JSON encode and graceful decode; byte-compatible with existing exports, locked by a round-trip test
- pantalla_ajustes delegates backup serialization to the service (inline jsonDecode/jsonEncode removed)
- New EstadoEcualizador ChangeNotifier owns all EQ state and persistence (principal/current/per-station presets, active flag), exposed via its own provider so EQ changes no longer rebuild EstadoRadio consumers
- EstadoRadio slims down ~210 lines and keeps 15 delegating compat members marked TODO(S4b) for the next slice to remove
- Player EQ toggle rewired to the new provider to avoid going stale
- 4 new tests (103 total green), flutter analyze clean
- 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
- Added state management for startup retry and custom station handling in `EstadoRadio`.
- Created tasks for implementing strict TDD with RED tests for HTTP failure retries and EQ persistence.
- Developed verification report to ensure compliance with TDD practices.
- Introduced fake services for testing, including `FakeServicioAudio`, `FakeServicioFavoritos`, and `FakeServicioRadio`.
- Implemented widget tests for `PantallaInicio` and `PantallaFavoritos` to validate UI behavior with custom stations.
- Enhanced `ServicioRadio` to support host rotation and retry logic for API calls.
- Established a new configuration file to enforce project constraints and testing rules.
**Fix 1 — HTTP cleartext (streams sin HTTPS):**
- Añadir android/app/src/main/res/xml/network_security_config.xml con
cleartextTrafficPermitted=true para permitir streams de radio HTTP
- Referenciar en AndroidManifest.xml con android:networkSecurityConfig
- Resuelve: 'Cleartext HTTP traffic to [host] not permitted' en ExoPlayer
- Radio Paradise (Dance Wave, HTTP) y otras radios HTTP funcionan ahora
**Fix 2 — Gestión de error TYPE_SOURCE y todos los PlaybackException:**
- Añadir listener en playbackEventStream.onError en PluriWaveAudioHandler
- _gestionarErrorReproduccion() emite AudioProcessingState.error al UI,
loggea el error y resetea el player a estado idle limpio
- _mensajeAmigable() traduce códigos ERROR_CODE_IO_*, ERROR_CODE_PARSING_*,
ERROR_CODE_DECODING_* y mensajes de Cleartext/HandshakeException a texto legible
- EstadoRadio.reproducir() captura la excepción y cancela el timer si estaba activo
- EstadoRadio escucha el estadoStream y cancela timer ante cualquier error
**Fix 3 — Artwork con certificado autofirmado:**
- errorWidget en CachedNetworkImage captura HandshakeException silenciosamente
- Muestra _iconoFallback (icono de radio) en lugar de imagen rota
- El error de artwork no se propaga ni interrumpe la reproducción
**Fix 4 — UI consistente en estado de error:**
- PantallaReproductor._Controles muestra mensaje + botón Reintentar en error
- PantallaReproductor._Artwork muestra overlay wifi_off en estado de error
- MiniReproductor muestra botón refresh (reintentar) en estado de error
- EstadoReproduccion.error ya estaba definido; ahora el estadoStream lo emite
- Timer cancelado automáticamente cuando la reproducción falla
- Test de smoke corregido (boilerplate MyApp → placeholder válido)
Fixes: cleartext HTTP, cert autofirmado, ExoPlayer TYPE_SOURCE, UI inconsistente
- ServicioAudio: delega a PluriWaveAudioHandler (audio_service) para
mantener audio vivo en background. AudioService.init() en main.dart.
onTaskRemoved() libera player. mediaItem con nombre/artista/artwork.
- ServicioRadio: lastcheckok=1 en todas las peticiones — solo emisoras
verificadas como funcionales por Radio Browser API.
- EstadoRadio: errorStream (broadcast) para errores de reproducción y
búsqueda. App.dart suscribe y muestra SnackBar flotante 3s.
Los errores de carga de lista siguen como banner inline.
- Icono: generado con SDXL (morado, ondas radio blancas, Material You).
5 densidades Android (48-192px), ic_launcher_round añadido.
