 # Changelog — PluriWave
 
-## [0.5.0] — 2026-04-04
-
-### Añadido
-- **VisualizadorAudio** — visualizador de barras animadas en `PantallaReproductor`. 24 barras verticales con movimiento orgánico pseudo-aleatorio (combinación de ondas seno con fases distintas). Se activa al reproducir y decae suavemente al parar. Sin FFT real ni permisos de micrófono — animación simulada visualmente equivalente a las apps de streaming.
-- **IndicadorReproduccion** — versión compacta de 3 barras para el `MiniReproductor`. Reemplaza el icono estático de radio y pulsa mientras hay audio activo.
-
-## [0.4.0] — 2026-04-04
-
-### Añadido
-- **PantallaReproductor** — pantalla completa del reproductor. Accesible tocando MiniReproductor o cualquier emisora. Incluye: artwork/logo grande con sombra animada al reproducir, nombre + chips info (país, idioma), codec/bitrate, controles play/pause/stop con indicador "en vivo", botón favorito (toggle), widget de timer (iniciar/cancelar desde la pantalla), animación de entrada slide-up. Transición pageRoute desde cualquier pantalla.
-- **PantallaAjustes** — pantalla de ajustes básica (tab nuevo en NavigationBar). Muestra estado del sistema (filtro emisoras, audio background), conteo de favoritos, preview de features próximas (Export/Import, radio personalizada, ecualizador).
-- **MiniReproductor** — ahora es tappable: toca la barra para abrir PantallaReproductor.
-- **NavigationBar** — añadido tab "Ajustes" (4 destinos: Inicio/Buscar/Favoritos/Ajustes).

-# TODO
-
-## Internacionalización AAA
-
-- [x] Diseñar una base de internacionalización profesional con ficheros ARB separados por idioma.
-- [x] Permitir que el usuario cambie el idioma manualmente desde la aplicación, sin depender únicamente del idioma del sistema.
-- [x] Añadir traducción inicial español/inglés para el shell, navegación, timer de sueño y selector de idioma.
-- [x] Añadir soporte inicial para un conjunto amplio de idiomas muy hablados: inglés, español, chino, hindi, árabe, portugués, francés, ruso, alemán, japonés, indonesio, bengalí e italiano.
-- [x] Ejecutar escaneo UTF-8 sobre ARB/código tocado y corregir corrupciones visibles en los textos migrados.
-- [ ] Validar no solo el guardado UTF-8 en código, sino también el render real en la aplicación para acentos, ñ, signos, alfabetos no latinos y direcciones RTL.
-- [ ] Repasar absolutamente todos los literales de la aplicación en todas las pantallas, componentes, servicios con mensajes visibles y notificaciones.
-- [ ] Soportar formatos locales de fecha, hora, números y duración usando helpers centralizados.
-- [ ] Resolver correctamente singular/plural y variantes por cantidad, por ejemplo `1 emisora` vs `2 emisoras`.
-- [ ] Revisar profesionalmente todas las traducciones nuevas con hablantes nativos o servicio especializado antes de considerarlas definitivas.
-- [ ] Preparar traducciones adicionales si se decide ampliar más allá del conjunto inicial.
-- [ ] Revisar la aplicación de Farolero como referencia para detectar el conjunto de idiomas que nos interesa mantener.
-- [ ] Verificar que no queda ningún literal hardcodeado fuera del sistema de traducciones.
-
-## UX y accesibilidad visual
-
-- [x] Revisar los paneles informativos superiores de cada pantalla: recuperar márgenes internos elegantes para que el texto no quede pegado a los bordes.
-- [x] Añadir comportamiento adaptativo en el header premium para escalas de texto grandes y pantallas estrechas.
-- [ ] Probar la aplicación con escalas de texto grandes/muy grandes del sistema en dispositivo real o golden tests.
-- [ ] Diseñar una solución elegante para textos largos en todos los paneles secundarios: reflow, límites razonables, scroll, wraps controlados y jerarquías que mantengan la estética AAA.
-
-## Grabaciones
-
-- [x] Añadir en Ajustes un acceso elegante para abrir la carpeta de grabaciones con el gestor de ficheros del sistema mediante intent.
-- [x] Añadir configuración de tamaño máximo de fichero de grabación; valor por defecto: 500 MB.
-- [x] Detener automáticamente la grabación si se para o pausa la reproducción.
-- [x] Detener automáticamente la grabación si se cambia de emisora.
-- [ ] Probar en Android real que el intent de carpeta funciona con rutas internas y rutas escogidas por el usuario.
-
-## Búsqueda de emisoras
-
-- [x] Añadir filtro de calidad mínima de reproducción en kbps en el buscador de emisoras.
-
-## Favoritos
-
-- [x] Revisar el sistema de guardado de favoritos en instalaciones nuevas y migradas: inicialización de SQLite, creación de ruta/base de datos, migraciones de columnas y refresco de estado tras guardar. Reporte: en un móvil no se están guardando favoritos.
-- [ ] Añadir tests de regresión para favoritos en base de datos real/migrada, incluyendo esquemas antiguos y primera instalación limpia.
-
-## Agrupaciones de favoritos
-
-- [x] Permitir crear listas de favoritos con nombre corto configurable por el usuario desde Ajustes.
-- [x] Mantener siempre un grupo interno por defecto traducible llamado "Sin asignar", no editable y no borrable.
-- [x] Gestionar desde la vista Favoritos qué emisoras pertenecen a cada agrupación/lista.
-- [x] Diseñar migración SQLite base para asociar favoritos existentes al grupo "Sin asignar" sin perder datos.
-- [x] Completar UI en Ajustes para crear, editar y borrar listas de favoritos.
-- [x] Completar UI en Favoritos para mover emisoras entre listas.

-# Alarmas Android en PluriWave
-
-PluriWave programa las alarmas con `AlarmManager.setAlarmClock`, porque es el camino Android pensado para despertadores visibles y de alta fiabilidad. Flutter conserva la configuración, la UI, la emisora y los fallbacks; Android se encarga de despertar la app en el momento exacto.
-
-## Flujo
-
-1. Flutter calcula la próxima ejecución según tipo, días, vacaciones y omisiones.
-2. `ServicioAlarmasAndroid` envía la programación al `MethodChannel pluriwave/alarm_scheduler`.
-3. `AlarmScheduler` registra:
-   - alarma principal con `setAlarmClock`;
-   - preaviso silencioso 30 minutos antes con `setExactAndAllowWhileIdle`.
-4. `PluriWaveAlarmReceiver` abre la app cuando suena la alarma.
-5. Flutter muestra `PantallaAlarmaSonando`, intenta reproducir la emisora y activa audio interno si la radio falla o tarda demasiado.
-
-## Permisos
-
-- `SCHEDULE_EXACT_ALARM`: necesario en Android 12+ para exactitud.
-- `POST_NOTIFICATIONS`: necesario en Android 13+ para el preaviso silencioso.
-- `WAKE_LOCK` y foreground media playback ya están declarados para la reproducción.
-
-## Fallbacks
-
-Si la emisora no existe, falla o no empieza a reproducir en unos segundos, la pantalla usa sonidos internos incluidos en `assets/audio/`. Esto evita una alarma silenciosa por problemas de red o de radio.
-
-## Vacaciones y omisiones
-
-Las vacaciones se guardan en Flutter. Las alarmas configuradas para pausar en vacaciones saltan automáticamente esos rangos y muestran la próxima fecha válida. El preaviso permite omitir la siguiente ejecución abriendo la app y aplicando la misma lógica de omisión persistente.

docs/alarmas-pantalla-apagada.md

@@ -1,30 +0,0 @@
-# Arquitectura de alarmas con pantalla apagada
-
-## Diagnóstico
-
-El flujo anterior hacía que Android recibiese la alarma con `AlarmManager`, pero el sonido real dependía de que se abriese `MainActivity` y de que Flutter llegase a pintar `PantallaAlarmaSonando`. Con pantalla apagada, Doze o restricciones del fabricante, ese arranque de UI puede retrasarse hasta que el usuario enciende la pantalla.
-
-## Decisión
-
-La alarma debe sonar desde Android nativo en cuanto llega `ACTION_FIRE`. Flutter pasa a ser la interfaz de control para detener, posponer y hacer handoff a la radio de la app, pero no el único origen del sonido.
-
-## Flujo recomendado
-
-1. `AlarmScheduler` programa la alarma con `setAlarmClock` y fallback exact/inexact.
-2. `PluriWaveAlarmReceiver` recibe `ACTION_FIRE`.
-3. El receiver arranca `PluriWaveAlarmService` como foreground service.
-4. El servicio toma un `PARTIAL_WAKE_LOCK`, muestra notificación foreground y reproduce audio con `USAGE_ALARM`.
-5. La UI Flutter se abre por full-screen intent si Android lo permite.
-6. Al detener/posponer desde Flutter, se manda comando nativo para parar el servicio.

-
-## Notas
-
-- El audio local interno es el fallback más fiable para pantalla apagada.
-- La radio remota puede fallar por red, DNS, TLS o timeout; por eso debe existir fallback interno.
-- Si un fabricante bloquea incluso servicios arrancados desde alarma, habrá que guiar al usuario con permisos de batería/autostart.

-
-Referencia interna: este archivo vive en `docs/` y no está listado en

-
-## Decisiones aplicadas
-
-- La grabación de radio se hace leyendo el stream HTTP original de la emisora y
-  escribiendo sus bytes a disco. No se graba micrófono ni salida del sistema.
-- La ventaja es que se conserva la calidad original del stream y se evita
-  recomprimir audio.
-- La forma de onda real se intenta capturar en Android con
-  `android.media.audiofx.Visualizer` usando el `androidAudioSessionId` expuesto
-  por `just_audio`.
-- Si Android deniega permisos o el dispositivo no permite capturar esa sesión,
-  la UI cae al visualizador animado anterior para no bloquear el reproductor.
-
-## Fuentes consultadas
-
-- `just_audio` expone `androidAudioSessionIdStream` para enlazar efectos o
-  visualizadores Android a la sesión activa:
-  https://pub.dev/packages/just_audio/versions/0.10.4
-- Android `Visualizer` permite capturar waveform de contenido en reproducción y

-- Radio Browser permite ordenar búsquedas por `bitrate` y expone campos

-## Hallazgos útiles
-
-- `AudioPlayer.play()` completa cuando la reproducción termina, se pausa o se detiene. En radio en vivo no representa simplemente “ya empezó a sonar”.
-- Las versiones antiguas de PluriWave que sí cambiaban de emisora usaban el flujo simple de `audio_service` + `just_audio`: `stop() -> setUrl() -> play()` dentro de `playMediaItem`.
-- La regresión apareció cuando mezclamos dos responsabilidades: usar `handler.emisoraActual` como estado técnico de audio y también como estado visual inmediato para mostrar el mini reproductor.
-- El logcat de 2026-05-21 mostró la media session de PluriWave atascada en `CONNECTING` sin `PlayerException`, con metadata de la emisora anterior (`Track FM`). Eso apunta a un player/ExoPlayer reutilizado que queda colgado entre `stop/setUrl/play`, no a un error HTTP visible.
-
-## Decisión aplicada en PluriWave
-
-- Mantener la selección visual inmediata en `EstadoRadio` mediante una emisora seleccionada propia, separada del `emisoraActual` interno del handler.
-- No usar `setAudioSource(..., preload: false)` como reemplazo de `setUrl(...)`: en esta app rompió incluso la primera conexión.
-- No esperar `play()` como operación de finalización para radio en vivo.
-- Al cambiar emisora, recrear el `AudioPlayer`/ExoPlayer para matar completamente la reproducción anterior antes de `setUrl(...)`.
-- Proteger `EstadoRadio.reproducir` con revisión para que una operación vieja no aplique presets/clicks encima de una nueva.
-
-## Intentos descartados
-
-- `setAudioSource(..., preload: false)`: teóricamente razonable, pero en PluriWave rompió la primera conexión.
-- Hacer que el handler publique `emisoraActual` antes de que el flujo histórico de audio avance: arregla el mini reproductor, pero cambia la semántica que tenían las versiones viejas.
-- Reutilizar siempre el mismo `AudioPlayer` con `stop()`: logcat mostró estado `CONNECTING` persistente sin excepción al cambiar/reintentar.

-# PluriWave · Guía de publicación automática en Google Play
-
-> Estado: en preparación  
-> Última revisión: 2026-05-27
-
-## Objetivo
-
-Dejar **PluriWave** con un flujo de publicación lo más automático posible:
-
-- `main` → desarrollo diario, pruebas y artefactos internos
-- `PRO` → publicación automática a **Google Play Internal Testing**
-
-## Estrategia acordada
-
-### Ramas
-
-- **`main`**
-  - desarrollo diario
-  - análisis, tests y builds internos
-  - NO publica en Google Play
-- **`PRO`**
-  - rama de release permanente
-  - al subir cambios aquí, se genera el **AAB release firmado**
-  - publica automáticamente en **Google Play · Prueba interna**
-
-### Publicación
-
-1. Bootstrap manual inicial en Play Console
-2. Configuración correcta del keystore de subida
-3. Integración con Google Play Developer API
-4. Automatización desde Gitea Actions
-
-## Estado actual del proyecto
-
-### Verificado en el repositorio
-
-- Existe workflow en `.gitea/workflows/build.yml`
-- Actualmente compila y firma correctamente en CI
-- Genera:
-  - APK release
-  - AAB release
-- Publica artefactos internos en `ftl-builds`
-- Ya existe soporte para keystore release desde `android/key.properties`
-
-### Verificado en Play Console
-
-- La app ya está creada
-- Nombre: `PluriWave`
-- Package: `es.freetimelab.pluriwave`
-- Ya se ha subido manualmente un **AAB** al canal de **prueba interna**
-- Producción sigue bloqueada por el requisito de:
-  - prueba cerrada
-  - 12 testers
-  - 14 días
-
-## Automatización prevista en CI
-
-### `main`
-
-- `flutter pub get`
-- `flutter analyze`
-- build release
-- publicación de APK/AAB en infraestructura interna
-
-### `PRO`
-
-- `flutter pub get`
-- `flutter analyze`
-- build release firmado
-- publicación de APK/AAB en infraestructura interna
-- subida automática del `.aab` a Google Play **track internal**
-
-## Secretos necesarios en Gitea
-
-### Ya usados por firma
-
-- `PLURIWAVE_KEYSTORE_PASSWORD`
-- `GITEA_TOKEN`
-
-### Necesarios para Play Store
-
-- `GOOGLE_PLAY_SERVICE_ACCOUNT_JSON`
-
-> Debe contener el JSON completo de una **Service Account** con acceso concedido en Play Console a esta aplicación.
-
-## Ficheros implicados
-
-- `.gitea/workflows/build.yml`
-- `fastlane/Fastfile`
-- `fastlane/Appfile`
-- `android/app/build.gradle.kts`
-
-## Siguiente validación manual
-
-Cuando la automatización quede desplegada:
-
-1. crear la rama `PRO` en remoto
-2. configurar `GOOGLE_PLAY_SERVICE_ACCOUNT_JSON`
-3. hacer push a `PRO`
-4. comprobar que:
-   - compila
-   - firma
-   - genera AAB
-   - sube a Google Play Internal Testing
-
-## Notas importantes
-
-- El canal automatizado inicial será **internal testing**, no producción
-- La primera publicación manual en Play Console ya quedó hecha
-- La automatización NO elimina el requisito posterior de closed testing antes de producción
