A *separate* named constant (initialised to 50) is used +rather than reusing the station cap because a folder tap has a higher distraction +cost than a station scroll, so the group cap must be tunable independently. + +## Data Flow + + Car ──getChildren(favoritos)──▶ Handler ──▶ carpetasFavoritos(grupos, favoritos) [pure] + ├─ non-empty custom groups → grupo: folders + └─ sin_asignar stations → emisora: leaves + Car ──getChildren(grupo:)─▶ Handler ──▶ hijosGrupo(id, favoritos) [pure] + EstadoRadio.cargarGruposFavoritos ──actualizarSnapshot(grupos:)──▶ FuenteEmisorasAutoLocal + cold bind ── grupos() ─ try/catch ─▶ ServicioFavoritos.obtenerGrupos() (never throws → []) + +## File Changes + +| File | Action | Description | +|------|--------|-------------| +| `lib/servicios/navegacion_auto.dart` | Modify | `grupos()` + `grupos` snapshot on `FuenteEmisorasAuto`/`Local` (try/catch → `[]`); `_prefijoGrupo`, `esCarpetaGrupo`, `carpetasFavoritos`, `hijosGrupo`, `itemGrupo` on `ConstructorArbolAuto` | +| `lib/servicios/servicio_audio.dart` | Modify | `getChildren`: `favoritos`→`carpetasFavoritos`, `grupo:`→`hijosGrupo`; thin branches only | +| `lib/estado/estado_radio.dart` | Modify | Push `actualizarSnapshot(grupos: _gruposFavoritos)` in `cargarGruposFavoritos()` | +| `test/servicios/navegacion_auto_test.dart` | Modify | Pure-function tests for the new builders | + +## Interfaces / Contracts + +```dart +abstract class FuenteEmisorasAuto { + // ...existing favoritos()/misEmisoras()/todas()/porUuid()... + Future> grupos(); // cold-safe; []-on-error + void actualizarSnapshot({ /* ...existing... */ List? grupos }); +} + +class ConstructorArbolAuto { + static const _prefijoGrupo = 'grupo:'; + static const _maxGruposPorFavoritos = 50; + bool esCarpetaGrupo(String id); // id.startsWith('grupo:') + List carpetasFavoritos({ + required List grupos, + required List favoritos }); // folders + ungrouped leaves + List hijosGrupo(String grupoMediaId, { + required List favoritos }); // members, sorted+capped + MediaItem itemGrupo(GrupoFavoritos g); // id 'grupo:', playable:false +} +``` + +`carpetasFavoritos`: skip `esSinAsignar` and empty custom groups → folders; append +`sin_asignar` members as `itemEmisora` leaves; cap folders at 50. `hijosGrupo`: +filter favorites by `grupoFavoritosId == id`, reuse `ordenarEmisoras` + 50 cap; +unknown/empty id → `const []`. + +## Testing Strategy + +| Layer | What to Test | Approach | +|-------|-------------|----------| +| Unit | No custom groups → all favorites as leaves (regression parity) | `carpetasFavoritos` | +| Unit | Custom groups → `grupo:` folders (playable:false) + ungrouped leaves, phone order | `carpetasFavoritos` | +| Unit | Empty custom group hidden; `sin_asignar` never a folder | `carpetasFavoritos` | +| Unit | >50 groups truncated | `carpetasFavoritos` | +| Unit | `hijosGrupo` filters by group, sorts, caps 50; unknown id → `[]` | `hijosGrupo` | +| Unit | `grupo:` id is no-op in `resolver`/`reproducirPorMediaId` (collision-free) | pure assertions | +| Manual (DHU) | Browse Favoritos → group → play; cold bind non-empty | user-side | + +## Migration / Rollout + +No migration.
