+# Player System Animation & Polish Audit
+
+## Context
+
+This is a Music Assistant client app (Ensemble) built with Flutter. The player system has undergone extensive development and now needs a comprehensive polish audit. The goal is buttery smooth 60fps animations and a premium user experience.
+
+## Architecture Overview
+
+The player system consists of three interconnected components:
+
+1. **Mini Player** (collapsed state) - Floating card at bottom, shows current track
+2. **Expanded Player** - Full-screen player with album art, controls, progress
+3. **Queue Panel** - Slides in from right of expanded player, shows playback queue
+
+Additionally:
+- **Player Selector** - Horizontal swipe between multiple players (collapsed mode)
+- **Device Reveal** - Swipe down from mini player to show available players
+
+## Key Files
+
+```
+lib/widgets/
+├── expandable_player.dart      # Main player widget (1800+ lines)
+├── global_player_overlay.dart  # Overlay wrapper, static accessors
+├── player/
+│   ├── queue_panel.dart        # Queue list with great_list_view
+│   ├── chapters_panel.dart     # Audiobook chapters
+│   └── mini_player_content.dart
+```
+
+## CRITICAL CONSTRAINTS
+
+1. **DO NOT MODIFY the queue list implementation** - It uses `great_list_view` package with `AutomaticAnimatedListView`. This was chosen specifically to avoid Flutter's grey screen overlay bug (#103804). The current implementation works correctly.
+
+2. **Preserve all existing functionality** - Focus on polish, not rewrites
+
+3. **Test changes incrementally** - This system is complex with many interdependencies
+
+## Audit Areas
+
+### 1. Animation Performance Audit
+
+Use sub-agents to analyze each animation system:
+
+**Agent 1: Expand/Collapse Animation**
+- Analyze `_controller` and `_expandAnimation`
+- Check for jank during morphing transition
+- Verify lerp functions are efficient
+- Look for unnecessary rebuilds during animation
+- Check `RepaintBoundary` placement
+
+**Agent 2: Queue Panel Animation**
+- Analyze `_queuePanelController` and `_queuePanelAnimation`
+- Verify slide-in/out is smooth
+- Check interaction with expanded player state
+- Verify the Listener-based swipe detection doesn't cause issues
+
+**Agent 3: Player Selector Animation**
+- Analyze horizontal swipe between players
+- Check `_slideOffset` and peek player animations
+- Verify finger-following feels natural
+- Look for edge cases with rapid swipes
+
+**Agent 4: Micro-interactions**
+- Play/pause button animations
+- Progress bar interactions
+- Volume swipe overlay
+- Favorite button feedback
+- Skip button responsiveness
+
+### 2. State Management Audit
+
+**Check for:**
+- Unnecessary `setState` calls during animations
+- ValueNotifier usage efficiency
+- Animation listener cleanup
+- Memory leaks from subscriptions
+- State synchronization between components
+
+### 3. Visual Polish Audit
+
+**Check for:**
+- Color transitions during expand/collapse
+- Text fade/scale animations
+- Image loading placeholders
+- Shadow/elevation consistency
+- Border radius morphing smoothness
+- Safe area handling
+
+### 4. Gesture Conflict Resolution
+
+**Verify:**
+- Vertical drag (expand/collapse) vs horizontal drag (player switch)
+- Queue panel swipe-right-to-close vs Dismissible swipe-left-to-delete
+- Edge dead zones for Android back gesture
+- Tap vs drag disambiguation
+
+### 5. Edge Cases
+
+**Test scenarios:**
+- Rapid expand/collapse
+- Swipe during animation
+- Back button during animations
+- Track change during queue scroll
+- Network image loading failures
+- Very long track/artist names
+
+## Execution Strategy
+
+```
+ultrathink: true
+```
+
+### Phase 1: Discovery (Read-Only)
+Launch parallel sub-agents to analyze each file:
+- Read and understand the animation architecture
+- Map all animation controllers and their relationships
+- Identify potential performance bottlenecks
+- Document current RepaintBoundary usage
+
+### Phase 2: Analysis Report
+Compile findings into categories:
+- **Critical**: Causes visible jank or bugs
+- **Important**: Noticeable but not breaking
+- **Nice-to-have**: Minor polish improvements
+
+### Phase 3: Implementation Plan
+For each finding:
+- Specific file and line numbers
+- Proposed change
+- Risk assessment
+- Testing approach
+
+### Phase 4: Incremental Fixes
+- One fix at a time
+- Build and test after each change
+- Verify no regressions
+
+## Output Format
+
+Provide a structured audit report:
+
+```markdown
+## Animation Audit Report
+
+### Executive Summary
+[2-3 sentences on overall state]
+
+### Critical Issues
+1. [Issue]: [File:Line] - [Description] - [Proposed Fix]

+### Architecture Observations
+[Notes on overall structure, patterns noticed]
+
+### Recommended Priority Order
+1. [First fix]
+2. [Second fix]
+...
+```
+
+## Success Criteria
+
+After this audit and fixes:
+- All animations run at consistent 60fps
+- No jank during any transition
+- Gestures feel responsive and natural
+- State transitions are seamless
+- No visual glitches or flickers
+- Memory usage is stable during interactions
+
+## Notes
+
+- The app uses adaptive theming (colors extracted from album art)
+- There's an `AnimationDebugger` utility for profiling
+- Position tracking uses a shared `PositionTracker` singleton
+- The player supports both music and audiobooks (different UI modes)

+# Android Auto Implementation Plan for Ensemble
+
+## 1. Overview
+
+This document describes adding Android Auto support to Ensemble. When a user connects their Android phone to a car head unit, Android Auto will browse and play music through Ensemble without touching the phone.
+
+### What we're building
+
+- A browse hierarchy (Favorites, Playlists, Albums, Radio) accessible from the car screen
+- Playback from Android Auto routes through the builtin (local) player, which streams through MA as normal
+- Voice search support
+
+### Why builtin player only
+
+Android Auto requires local audio output. The builtin player plays audio through `just_audio` on the device, which the car receives over Bluetooth. Remote MA players are irrelevant in a car context.
+
+---
+
+## 2. Architecture
+
+### Provider reference
+
+`MassivAudioHandler` has no reference to `MusicAssistantProvider` today. The handler is created before the provider (in `main()` before `runApp`). Solution: add a `setProvider()` method and call it from `_MusicAssistantAppState.initState()`.
+
+```
+main.dart
+  audioHandler = await AudioService.init(...)   // global, created first
+  runApp(MusicAssistantApp())
+    _MusicAssistantAppState.initState()
+      _musicProvider = MusicAssistantProvider()
+      audioHandler.setProvider(_musicProvider)  // NEW
+```
+
+### Browse → play call flow
+
+```
+Android Auto          MassivAudioHandler              MusicAssistantProvider
+     |                       |                                |
+  getChildren('root') -----> | returns category items        |
+  getChildren('cat|playlists')-> | SyncService.cachedPlaylists  |
+  getChildren('playlist|lib|5')-> | provider.getPlaylistTracksWithCache()
+                             |  populates _trackQueueCache   |
+  playFromMediaId('track|lib|7|plist|lib|5') ->               |
+                             | lookup _trackQueueCache        |
+                             | provider.playTracks(builtinId, tracks, startIndex: i)
+```
+
+---
+
+## 3. Media ID Scheme
+
+Separator: `|` (pipe). Provider names use underscores/colons, never pipes — safe.
+
+| ID | Meaning |
+|----|---------|
+| `root` | Root (browsable) |
+| `recent` | Currently playing track (playable) |
+| `cat\|favorites` | Favorites category (browsable) |
+| `cat\|playlists` | Playlists category (browsable) |
+| `cat\|albums` | Albums category (browsable) |
+| `cat\|radio` | Radio stations category (browsable) |
+| `playlist\|{provider}\|{itemId}` | A playlist (browsable) |
+| `album\|{provider}\|{itemId}` | An album (browsable) |
+| `track\|{tProvider}\|{tItemId}\|{ctxType}\|{ctxProvider}\|{ctxId}` | A track in context (playable) |
+| `radio\|{provider}\|{itemId}` | A radio station (playable) |
+
+The `ctxType|ctxProvider|ctxId` suffix in track IDs encodes the parent container. Context types: `plist`, `album`, `favs`, `search`.
+
+**Track queue cache key** = `{ctxType}|{ctxProvider}|{ctxId}` (e.g. `plist|spotify|abc`). Stored when building children, looked up in `playFromMediaId`.
+
+---
+
+## 4. Browse Hierarchy
+
+```
+root
+├── recent              (playable, shown if something is/was playing)
+├── cat|favorites       (browsable → favorite tracks, all playable)
+├── cat|playlists       (browsable → list of playlists, each browsable)
+│   └── playlist|{provider}|{id}  → tracks (playable)
+├── cat|albums          (browsable → list of albums, each browsable)
+│   └── album|{provider}|{id}     → tracks (playable)
+└── cat|radio           (browsable → radio stations, each playable)
+```
+
+Artists are **not included**. Navigating Artist → Albums → Album → Tracks is four taps — too many while driving. Can be added later.
+
+---
+
+## 5. Track Queue Cache
+
+Tapping a track in Android Auto should play the full album/playlist from that track, not just the single track. The handler caches track lists when building children:
+
+```dart
+// Key: ctxKey e.g. "plist|spotify|abc" or "album|library|42" or "favs||"
+// Value: ordered list of tracks in that container
+final Map<String, List<ma.Track>> _trackQueueCache = {};
+```
+
+When `getChildren('playlist|spotify|abc')` is called:
+1. Fetch tracks via `provider.getPlaylistTracksWithCache('spotify', 'abc')`
+2. Store `_trackQueueCache['plist|spotify|abc'] = tracks`
+3. Return each track as a playable `MediaItem` with id `track|{t.provider}|{t.itemId}|plist|spotify|abc`
+
+When `playFromMediaId('track|lib|7|plist|spotify|abc')` is called:
+1. Parse ctxKey = `plist|spotify|abc`
+2. Look up `_trackQueueCache['plist|spotify|abc']`
+3. Find track index where `itemId == '7'`
+4. Call `provider.playTracks(builtinId, tracks, startIndex: index)`
+
+---
+
+## 6. Key Code for `massiv_audio_handler.dart`
+
+### New imports
+
+```dart
+import 'package:rxdart/rxdart.dart';
+import '../../providers/music_assistant_provider.dart';
+import '../settings_service.dart';
+import '../sync_service.dart';
+import '../../models/media_item.dart' as ma;
+```
+
+Note: `audio_service` exports its own `MediaItem`. Use `ma.MediaItem`, `ma.Track`, `ma.Album`, `ma.Playlist` for app models. The bare `MediaItem` refers to the audio_service type throughout new methods.
+
+### New fields
+
+```dart
+MusicAssistantProvider? _provider;
+final Map<String, ma.Track> _trackQueueCache = {}; // ctxKey -> tracks (see section 5)
+final Map<String, BehaviorSubject<Map<String, dynamic>>> _childrenSubjects = {};
+
+void setProvider(MusicAssistantProvider provider) {
+  _provider = provider;
+}
+```
+
+### `getChildren`
+
+```dart
+@override
+Future<List<MediaItem>> getChildren(String parentMediaId,
+    [Map<String, dynamic>? options]) async {
+  final provider = _provider;
+  if (provider == null) return [];
+
+  switch (parentMediaId) {
+    case AudioService.browsableRootId:
+      return _buildRoot(provider);
+    case 'cat|favorites':
+      return _buildFavorites(provider);
+    case 'cat|playlists':
+      return _buildPlaylistList(provider);
+    case 'cat|albums':
+      return _buildAlbumList(provider);
+    case 'cat|radio':
+      return _buildRadioList(provider);
+    default:
+      if (parentMediaId.startsWith('playlist|')) {
+        final parts = parentMediaId.split('|');
+        if (parts.length >= 3) return _buildPlaylistTracks(provider, parts[1], parts[2]);
+      }
+      if (parentMediaId.startsWith('album|')) {
+        final parts = parentMediaId.split('|');
+        if (parts.length >= 3) return _buildAlbumTracks(provider, parts[1], parts[2]);
+      }
+      return [];
+  }
+}
+```
+
+### `playFromMediaId`
+
+```dart
+@override
+Future<void> playFromMediaId(String mediaId, [Map<String, dynamic>? extras]) async {
+  final provider = _provider;
+  if (provider == null) return;
+
+  final playerId = await SettingsService.getBuiltinPlayerId();
+  if (playerId == null) return;
+
+  _logger.log('AndroidAuto: playFromMediaId $mediaId');
+
+  try {
+    if (mediaId == 'recent') {
+      await provider.playPauseSelectedPlayer();
+      return;
+    }
+
+    if (mediaId.startsWith('radio|')) {
+      final parts = mediaId.split('|'); // ['radio', provider, itemId]
+      if (parts.length < 3) return;
+      final station = provider.radioStations.firstWhere(
+        (s) => s.provider == parts[1] && s.itemId == parts[2],
+        orElse: () => throw Exception('Station not found: $mediaId'),
+      );
+      await provider.playRadio(playerId, station);
+      return;
+    }
+
+    if (mediaId.startsWith('track|')) {
+      // Format: track|{tProvider}|{tItemId}|{ctxType}|{ctxProvider}|{ctxId}
+      final parts = mediaId.split('|');
+      if (parts.length < 6) return;
+      final tProvider = parts[1];
+      final tItemId = parts[2];
+      final ctxKey = parts.sublist(3).join('|');
+
+      final trackList = _trackQueueCache[ctxKey];
+      if (trackList == null || trackList.isEmpty) {
+        // Fallback: play single track (minimal Track object)
+        await provider.playTrack(playerId, ma.Track(itemId: tItemId, provider: tProvider, name: ''));
+        return;
+      }
+
+      final index = trackList.indexWhere((t) => t.provider == tProvider && t.itemId == tItemId);
+      await provider.playTracks(playerId, trackList, startIndex: index < 0 ? 0 : index);
+      return;
+    }
+  } catch (e) {
+    _logger.log('AndroidAuto: playFromMediaId error: $e');
+  }
+}
+```
+
+### `search`
+
+```dart
+@override
+Future<List<MediaItem>> search(String query, [Map<String, dynamic>? extras]) async {
+  final provider = _provider;
+  if (provider == null || query.trim().isEmpty) return [];
+
+  try {
+    final results = await provider.searchWithCache(query);
+    final tracks = (results['tracks'] ?? []).whereType<ma.Track>().toList();
+    const ctxKey = 'search||';
+    _trackQueueCache[ctxKey] = tracks;
+
+    return tracks.map((t) => MediaItem(
+      id: 'track|${t.provider}|${t.itemId}|$ctxKey',
+      title: t.name,
+      artist: t.artistsString,
+      album: t.album?.name,
+      duration: t.duration,
+      artUri: _artUri(provider, t),
+      playable: true,
+    )).toList();
+  } catch (e) {
+    _logger.log('AndroidAuto: search error: $e');
+    return [];
+  }
+}
+```
+
+### `subscribeToChildren`
+
+```dart
+@override
+ValueStream<Map<String, dynamic>> subscribeToChildren(String parentMediaId) {
+  _childrenSubjects[parentMediaId] ??= BehaviorSubject.seeded({});
+  return _childrenSubjects[parentMediaId]!.stream;
+}
+```
+
+### `_artUri` helper
+
+```dart
+Uri? _artUri(MusicAssistantProvider provider, ma.MediaItem item) {
+  final url = provider.getImageUrl(item, size: 256);
+  return url != null ? Uri.tryParse(url) : null;
+}
+```
+
+---
+
+## 7. Files to Change
+
+### `pubspec.yaml`
+Add `rxdart: ^0.28.0` as direct dependency. The `^0.28.0` constraint matches the already-resolved transitive version so no upgrade occurs.
+
+### `android/app/build.gradle`
+Change:
+```groovy
+minSdkVersion flutter.minSdkVersion
+```
+To:
+```groovy
+minSdkVersion 23
+```
+Android Auto requires API 23+. `flutter.minSdkVersion` resolves to 21 — too low.
+
+### `android/app/src/main/AndroidManifest.xml`
+Add inside `<application>` tag:
+```xml
+<meta-data
+    android:name="com.google.android.gms.car.application"
+    android:resource="@xml/automotive_app_desc" />
+```
+The `MediaBrowserService` intent filter on `AudioService` is already present — no changes needed there.
+
+### `android/app/src/main/res/xml/automotive_app_desc.xml` (NEW)
+```xml
+<?xml version="1.0" encoding="utf-8"?>
+<automotiveApp>
+    <uses name="media" />
+</automotiveApp>
+```
+
+### `lib/main.dart`
+In `_MusicAssistantAppState.initState()`, after creating `_musicProvider`:
+```dart
+audioHandler.setProvider(_musicProvider);
+```
+
+### `lib/services/audio/massiv_audio_handler.dart`
+Add ~200 lines. New imports, fields, `setProvider()`, `getChildren()`, `playFromMediaId()`, `search()`, `subscribeToChildren()`, and private builder helpers. All existing code is untouched.
+
+---
+
+## 8. Testing with DHU (No Car Required)
+
+### Install DHU
+In Android Studio: SDK Manager → SDK Tools → Android Auto Desktop Head Unit Emulator.
+
+Or via command line:
+```bash
+sdkmanager "extras;google;auto"
+```
+
+### Enable Android Auto developer mode on phone
+1. Settings → Apps → Android Auto → tap version number 10 times
+2. In Android Auto developer settings: enable "Unknown sources"
+
+### Run the test session
+```bash
+# Terminal 1: forward the port
+adb forward tcp:5277 tcp:5277
+
+# Terminal 2: start the DHU
+$ANDROID_SDK_ROOT/extras/google/auto/desktop-head-unit
+```
+
+In Android Auto developer settings on phone: tap "Start head unit server".
+
+### Build and install
+```bash
+flutter build apk --debug
+adb install build/app/outputs/flutter-apk/app-debug.apk
+```
+
+Launch Ensemble on phone first (so audio service starts). Then tap the media icon in DHU — Ensemble should appear.
+
+### Troubleshooting
+
+| Symptom | Cause | Fix |
+|---------|-------|-----|
+| App not visible in DHU | Missing `automotive_app_desc.xml` or wrong meta-data name | Check manifest and XML |
+| App visible, browse is empty | `setProvider` not yet called | Check `initState` wiring |
+| Build fails | `minSdkVersion` too low | Check `build.gradle` |
+| Track plays but wrong song | `_trackQueueCache` miss | Ensure `getChildren` ran before `playFromMediaId` |
+
+---
+
+## 9. Implementation Order
+
+Do these steps in order to test incrementally:
+
+1. Android config files (`build.gradle`, `AndroidManifest.xml`, `automotive_app_desc.xml`) — verify app appears in DHU before writing Dart
+2. `pubspec.yaml` + `flutter pub get`
+3. `massiv_audio_handler.dart`: add `setProvider`, fields, `subscribeToChildren` — minimum to not crash
+4. `main.dart`: wire `setProvider`
+5. `massiv_audio_handler.dart`: `getChildren` with hardcoded root categories — verify tree appears in DHU
+6. `massiv_audio_handler.dart`: add all `_build*` helpers one by one, test each
+7. `massiv_audio_handler.dart`: add `playFromMediaId` — test track playback
+8. `massiv_audio_handler.dart`: add `search` — test voice search
+
+---
+
+## 10. Not In Scope
+
+- **Artists browse** — too many taps for driving; albums alone suffice
+- **Audiobooks/podcasts** — different UX needs; add later
+- **Queue management from Android Auto** — MA queue model is complex
+- **Push updates** — `notifyChildrenChanged` stubbed but not wired to sync events
+- **Android Automotive OS** — different platform, requires a separate flavor

-  - [x] `library_screen.dart` - **IMPLEMENTED** play track functionality
-  - [x] `expandable_player.dart` - enhanced comment with API limitations
-
----
-
-## Phase 2: Performance Fixes (2-3 days)
-*Medium effort, significant performance gains*
-
-- [x] Fix slider setState spam - use ValueNotifier pattern (`expandable_player.dart`)
-- [x] Replace volume polling with events (`volume_control.dart`) - removed polling loop
-- [x] Cache `Theme.of(context)` lookups - removed unused lookup in `search_screen.dart`
-- [x] Move `SystemChrome` out of build() (`main.dart`) - created SystemUIWrapper widget

+# Music Assistant 2.8.0 Beta 14 — Impact on Ensemble
+
+**Date:** 2026-03-03
+**Current server:** 2.8.0 beta 12
+**Target server:** 2.8.0 beta 14 (released March 2, 2026)
+
+---
+
+## Summary
+
+Beta 14 is a large release (50+ PRs). The headline change — merging multi-protocol players into a single entity — directly overlaps with Ensemble's client-side Cast↔Sendspin consolidation logic. Sendspin also received a major v4.0 overhaul. Most changes should degrade gracefully but player ID persistence will break on upgrade.
+
+---
+
+## Breaking: Player Merging (PR #3150)
+
+MA now merges players that support multiple protocols (e.g. a Chromecast with Cast + Sendspin) into a **single player entity** server-side. Previously these appeared as two separate players.
+
+> *"After this change, all your players will be reset. If you previously had multiple players in Music Assistant per protocol, this will now show up as one single player."*
+
+### What Ensemble does today
+
+Ensemble handles this client-side in `music_assistant_provider.dart:4271-4406`:
+
+- `_castToSendspinIdMap` maps Cast IDs → Sendspin IDs
+- When Sendspin is grouped: hides Cast player, shows Sendspin (renamed to base name)
+- When ungrouped: hides Sendspin, shows original Cast
+- Mappings persisted to database for cold start restoration
+
+### Impact on Ensemble
+
+| Component | Location | Impact | Severity |
+|---|---|---|---|
+| `_castToSendspinIdMap` + consolidation logic | `provider:4271-4406` | Dead code — server no longer sends separate players | Medium |
+| `isManuallySyncedPlayer()` ID translation | `provider:533-595` | Lookups against stale map fail silently (returns `false`) | Low |
+| Player selection persistence | Settings + DB | **Stored player IDs invalid after upgrade** — all players reset | **High** |
+| `_handlePlayerUpdatedEvent()` ID matching | `provider:2956-3358` | Events arrive with new merged IDs, old translation won't match | Medium |
+| Database-persisted Cast↔Sendspin mappings | `DatabaseService` | Stale data, won't match anything | Low |
+
+### Assessment
+
+The consolidation logic should degrade gracefully — it won't find Sendspin suffixes to strip or Cast pairs to merge, so the server's already-merged players pass through `filterPlayers()` as-is. The main risk is **player selection breaking** because saved player IDs no longer exist.
+
+### Action required
+
+1. Verify the existing fallback logic (`provider:4427-4465`) gracefully re-selects when the stored `selectedPlayerId` doesn't exist in the player list
+2. Remove or gate the Cast↔Sendspin consolidation code behind a server version check (on beta 14+ it's unnecessary and could cause confusion)
+3. Clear stale database mappings on first connection to a beta 14+ server
+
+---
+
+## Sendspin v4.0 (PR #3158)
+
+Major rewrite of the Sendspin server.
+
+### Changes
+
+- New `SendspinPlaybackSession` coordinator architecture
+- Per-member DSP pipelines, dynamic group membership, late-join audio backfill
+- Max buffer capacity 5 → 30 seconds
+- Multiple Sendspin servers with automatic failover
+- Per-client codec/sample-rate/bit-depth options
+- Album artwork persists during skip/pause
+- Reduced latency for live streams
+
+### Impact on Ensemble
+
+| Change | Impact |
+|---|---|
+| New session architecture | **Likely compatible** — sendspin-js only bumped 2.0.0 → 2.0.1 (minor), suggesting wire protocol didn't fundamentally change |
+| Per-client codec options | `stream/start` may contain new fields — safe if Ensemble ignores unknown fields |
+| Multiple servers with failover | Ensemble's 3-tier connection strategy may need awareness |
+| Buffer increase | No client impact |
+
+### Action required
+
+1. Test Sendspin connection against beta 14 — verify `client/hello`, `stream/start`, state reporting all still work
+2. Confirm unknown fields in protocol messages are ignored gracefully
+
+---
+
+## Sendspin-Chromecast Bridge (PR #3255)
+
+Replaces the inline experimental Sendspin mode in `ChromecastPlayer` with a dedicated bridge. Cast devices now use a Cast receiver app with an embedded JS Sendspin client.
+
+### Impact on Ensemble
+
+- **Direct impact: None** — Ensemble is a Sendspin client itself, not going through Cast
+- **Indirect:** Changes how grouped Cast players behave, which could affect `GroupVolumeManager`
+
+---
+
+## Group Volume / Grouping Fixes
+
+| PR | Change | Ensemble Impact |
+|---|---|---|
+| #3192 | Fix grouping for players whose native protocol is also a protocol of other players | Bidirectional grouping translation — may affect group detection logic |
+| #3205 | Fix group mute for protocol-synced players (`player.state.group_members` vs `player.group_members`) | `GroupVolumeManager` may see different/correct member lists |
+| #3277 | Fix `volume_up`/`volume_down` for group players | Server-side fix, should improve behavior |
+| #3118 | Fix sync groups losing members on power off | Affects dynamic group management |
+
+### Action required
+
+1. Test group volume behavior — may "just work better" with server-side fixes
+2. Verify `GroupVolumeManager` handles any changes to `group_members` field population
+
+---
+
+## Sendspin Bug Fixes
+
+| PR | Fix | Ensemble Relevance |
+|---|---|---|
+| #3191 | DSP not applying for Sendspin players | DSP config stored on parent player, looked up by protocol player ID — now fixed |
+| #3249 | Update to aiosendspin 4.2.0 | Library update, potential behavior changes |
+| #3250 | Metadata sending wrong progress when paused | Progress reporting fix — Ensemble's position tracker may see better data |
+| #3258 | Floating point for internal audio data | Audio quality improvement, no client impact |
+
+---
+
+## New APIs — Opportunities
+
+| Feature | PR | Details | Ensemble Opportunity |
+|---|---|---|---|
+| Playback speed | #3198 | `player_queues/set_playback_speed`, stored in `queue.extra_attributes["playback_speed"]` | Great for audiobooks/podcasts |
+| Save queue to playlist | #3149 | `save_as_playlist` command on player queue controller | Easy feature add |
+| Mixed-media playlists | #3216 | Playlists can contain tracks + podcasts + audiobooks. DB schema bumped to v30. `get_playlist_tracks()` returns `Sequence[PlaylistPlayableItem]` | Playlist screens may need to handle heterogeneous items |
+| Genres v2 | #3164 | New browsing category with icons and SVG support | New library section |
+
+---
+
+## Also Changed in Beta 13 (Skipped)
+
+Relevant changes from beta 13 (between current beta 12 and target beta 14):
+
+- Group volume mute support (#3034)
+- Frontend prepared for multiprotocol support (#1409) — groundwork for beta 14 merging
+- IPv6 support for zeroconf, stream server, AirPlay (#3086)
+- Snapcast player availability alignment (#3104)
+- DLNA reconnection fix (#3132)
+
+---
+
+## Recommended Action Plan
+
+### Before upgrading
+
+- [ ] Verify player selection fallback handles missing player IDs gracefully
+- [ ] Back up current configuration
+
+### Immediate (after upgrading)
+
+- [ ] Test Sendspin protocol compatibility (connection, streaming, state reporting)
+- [ ] Test player list — confirm merged players appear correctly without client-side consolidation
+- [ ] Test group volume behavior with new server-side fixes
+- [ ] Test player selection persistence across app restarts
+
+### Short-term
+
+- [ ] Remove or version-gate Cast↔Sendspin consolidation code
+- [ ] Clear stale database mappings on beta 14+ detection
+- [ ] Test mixed-media playlist handling if playlists are used
+
+### Opportunistic
+
+- [ ] Add playback speed control (audiobook/podcast feature)
+- [ ] Add save-queue-to-playlist
+- [ ] Explore Genres v2 browsing

+# Release Notes Draft
+
+## v2.9.2-beta (TBD)
+
+### New Features
+
+#### Context Menus
+- **Long-press context menus on all media items**: Albums, artists, tracks, playlists, podcasts, and radio stations now all support long-press to show a context menu with Play, Add to Library, and Favorite options.
+
+#### Podcasts
+- **Podcast episode detail screen**: Tap "View Details" from episode context menu to see full scrollable description, publish date, duration, with Play, Play On, and Add to Queue actions.
+- **Episode sorting**: Sort podcast episodes by newest first, oldest first, alphabetical, or duration.
+
+#### Audio Quality
+- **Hi-res audio badge**: Track listings now show a hi-res badge when high quality audio is available.
+
+### Improvements
+
+#### UI/UX
+- **New library icon**: Replaced confusing library icon with clearer book icon (book_2) across bottom nav, search filter, detail screens, and context menus. Filled when in library, outlined when not.
+- **Player selector**: Replaced popup dialog with player select overlay for queue actions.
+- **Search library filter**: Filled icon indicates active filter state without background highlight.
+- **Context menu polish**: Slightly larger buttons (46px), wider menu (185px), consistent text colors that don't pick up adaptive theming.
+- **Navigation transitions**: Smoother fade/slide animations between screens.
+- **Hero animations**: Podcast episode images animate smoothly to detail screen.
+
+#### Performance
+- **Library list optimization**: Standardized list item heights with itemExtent, reduced image cache sizes for smoother scrolling.
+- **Palette extraction**: Moved to isolate for better UI responsiveness during color extraction.
+- **Provider selects**: Optimized provider state watching to reduce unnecessary rebuilds.
+
+### Bug Fixes
+
+#### Audiobooks
+- **Fixed audiobooks not loading after provider re-add**: When removing and re-adding an AudiobookShelf provider, the app would show 0 audiobooks because saved library paths referenced the old provider instance ID. Now automatically clears stale settings and falls back to the library_items API.
+
+- **Fixed duplicate provider filter options**: After re-adding a provider, two entries for the same provider could appear in the library filter menu. Now deduplicates providers by name, keeping the one with more items.
+
+- **Fixed multiple accounts of same service not showing**: When you have multiple accounts of the same service (e.g., two Spotify accounts for different family members), only one would appear in the library menu provider toggles. Now all accounts with distinct names are shown.
+
+- **Fixed audiobook year sorting**: Sort by year now works correctly for audiobooks. Fixed two issues:
+  - Year data is now properly extracted from ABS's `metadata.release_date` field (handles both "2024" and "2024-01-15" formats)
+  - Sort handler now properly supports ascending and descending year sorts
+
+#### Library Sorting
+- **Fixed letter scrollbar showing irrelevant letters**: When sorting by date or play count, the scrollbar popup now hides instead of showing meaningless letters. Shows contextual info based on sort type (letters for alphabetical, years for year sort, hidden for date/count sorts).
+
+- **Fixed sorting not working for date added, last played, play count**: These sort options now correctly preserve server-side sorting instead of re-sorting alphabetically on the client. Affected albums, artists, and tracks tabs.
+
+- **Fixed playlists sorting**: Modified, last played, and play count sorting now works for playlists by properly requesting sorted data from the server.
+
+- **Fixed ascending/descending not working**: Sort direction now properly applies for all sort types across albums, artists, playlists, and audiobooks.
+
+- **Fixed list not updating when sort order changes**: Added sort order to ListView/GridView keys to force UI rebuilds when changing sort direction.
+
+#### Provider Management
+- **Fixed stale provider IDs persisting in settings**: When toggling providers, stale provider instance IDs (from removed providers) are now automatically cleaned up from saved settings.
+
+#### Playback
+- **Fixed Spotify external source detection** (issue #27): Properly detects when Spotify is the music provider.
+- **Fixed foreground service not stopping** (issue #51): Auto-stops after 30 minutes idle.
+- **Fixed Sendspin proxy auth**: Now works correctly for local network connections.
+
+#### UI Fixes
+- **Fixed nav bar hidden when no player selected**: Navigation bar now always visible.
+- **Fixed Flutter 3.38 slider grey rectangles**: Volume and seek sliders render correctly.
+- **Fixed library tab scroll position**: Maintains position when switching tabs.
+
+### Technical Changes
+- Flutter 3.38 compatibility
+- Simplified authentication using MA built-in auth
+- Added `material_symbols_icons` package for book_2 icon
+- Added `ScrollbarDisplayMode` enum (`letter`, `year`, `count`, `none`) for contextual scrollbar popups
+- Added `updateCachedAlbums()`, `updateCachedArtists()`, `updateCachedPlaylists()` methods to SyncService for proper cache synchronization with sorted data
+- Provider filter now validates against available providers when toggling, not just on initial load
+- Removed Selector caching from albums and artists tabs to ensure proper rebuilds when source tracking updates
+- Options menu provider toggles now use Consumer to watch Provider state directly
+- Centralized player selector logic in GlobalPlayerOverlay.showPlayerSelectorForAction()

+# Search Improvements
+
+Branch: `feature/search-improvements`
+
+## Completed
+
+- [x] Add playlists and audiobooks to search results
+  - Parse from MA API response
+  - Filter chips for each type
+  - Tile builders with navigation to detail screens
+
+- [x] Unified Relevance-Based "All" Results
+  - Scoring algorithm implemented:
+    - Exact match: 100 points
+    - Starts with query: 80 points
+    - Contains query (word boundary): 60 points
+    - Contains query (anywhere): 40 points
+    - Fuzzy match: 20 points
+    - Bonus for library items (albums): +10 points
+    - Bonus for favorites: +5 points
+    - Secondary field matching (artist name in albums/tracks)
+  - Merged all results into single sorted list
+  - Type indicators in subtitle (e.g., "Artist • Album")
+
+- [x] Smart Cross-Referencing
+  - Extracts unique artists from matched tracks/albums
+  - Filters to artists whose name contains query words (min 3 chars)
+  - Adds cross-referenced artists with lower relevance score (25)
+  - Avoids duplicates with direct search results
+
+- [x] Past Searches Row
+  - Added SearchHistory table to database (schema v4)
+  - Saves successful searches (deduplicated, max 10)
+  - Displays as ActionChips in empty state
+  - Clicking chip performs that search
+
+## Remaining Ideas (Lower Priority)
+
+- **Library-only toggle:** Add switch to filter search to library items only (MA API supports this)
+- **Voice search:** Add microphone button if platform supports speech recognition
+- **Search suggestions:** Typeahead from library as user types
+- **Quick actions:** Long-press result for play/queue options without navigating
+- **Clear history in settings:** Add option to clear search history

-# Ensemble Performance Audit: Animation Smoothness Optimization
-
-**Date**: 2025-12-05
-**Target**: Achieve buttery-smooth animations comparable to Symphonium media player
-**Branch**: performance/animation-smoothness
-**Auditor**: Claude Code
-
----
-
-## Executive Summary
-
-This audit focuses specifically on Flutter performance optimizations to achieve 60fps+ animations and eliminate jank in the Ensemble music player app. The codebase has good foundational work (RepaintBoundary on cards, image caching, AutomaticKeepAliveClientMixin), but there are several opportunities for improvement to match the smoothness of premium music players like Symphonium.
-
-### Performance Status
-
-**Current State:**
-- ✅ RepaintBoundary on AlbumCard and ArtistCard
-- ✅ Image caching with cacheWidth/cacheHeight
-- ✅ AutomaticKeepAliveClientMixin on row widgets
-- ⚠️ Missing keys on list items
-- ⚠️ Missing const constructors in many widgets
-- ⚠️ ListView.builder without itemExtent where applicable
-- ⚠️ setState calls could be more targeted
-- ⚠️ No state restoration (scroll positions lost on navigation)
-- ⚠️ Hero animations missing in Library screen
-
-### Performance Impact Categories
-
-| Category | Impact | Complexity | Priority |
-|----------|--------|------------|----------|
-| Quick Wins | High | Low | Critical |
-| Widget Rebuilds | High | Medium | High |
-| Animation Tuning | Medium | Low | High |
-| List Performance | Medium | Low | Medium |
-| State Restoration | Low | Medium | Low |
-
----
-
-## Category 1: Quick Wins (Immediate Impact, Low Effort)
-
-### QW-1: Add Missing `const` Constructors
-
-**Issue**: Many stateless widgets lack const constructors, causing unnecessary rebuilds.
-
-**Impact**: High - const widgets are cached by Flutter and reused, reducing rebuild overhead significantly.
-
-**Locations**:
-- `/home/home-server/Ensemble/lib/screens/library_artists_screen.dart:8` - LibraryArtistsScreen
-- `/home/home-server/Ensemble/lib/screens/library_albums_screen.dart:7` - LibraryAlbumsScreen
-- Various SizedBox, Padding, Icon widgets throughout
-
-**Fix**:
-```dart
-// Before:
-class LibraryArtistsScreen extends StatelessWidget {
-  LibraryArtistsScreen({super.key});
-
-// After:
-class LibraryArtistsScreen extends StatelessWidget {
-  const LibraryArtistsScreen({super.key});
-```
-
-**Estimated Savings**: 5-10% reduction in widget rebuilds
-
----
-
-### QW-2: Add Keys to List Items
-
-**Issue**: ListView.builder and GridView.builder items lack keys, causing Flutter to rebuild entire items instead of reusing them.
-
-**Impact**: High - Without keys, Flutter can't track widgets during list updates, causing full rebuilds.
-
-**Locations**:
-- `/home/home-server/Ensemble/lib/screens/library_artists_screen.dart:88-95` - Artists list
-- `/home/home-server/Ensemble/lib/screens/library_albums_screen.dart:87-103` - Albums grid
-- `/home/home-server/Ensemble/lib/widgets/album_row.dart:89-104` - Album horizontal list
-- `/home/home-server/Ensemble/lib/widgets/artist_row.dart:89-104` - Artist horizontal list
-
-**Fix**:
-```dart
-// Before:
-itemBuilder: (context, index) {
-  final artist = provider.artists[index];
-  return _buildArtistTile(context, artist, provider);
-}
-
-// After:
-itemBuilder: (context, index) {
-  final artist = provider.artists[index];
-  return _buildArtistTile(
-    context,
-    artist,
-    provider,
-    key: ValueKey(artist.uri ?? artist.itemId),
-  );
-}
-```
-
-**Estimated Savings**: 15-25% reduction in list scroll jank
-
----
-
-### QW-3: Add itemExtent to Horizontal Lists
-
-**Issue**: Horizontal lists don't specify itemExtent, forcing Flutter to measure every item.
-
-**Impact**: Medium - itemExtent allows Flutter to calculate layout without measuring, improving scroll performance.
-
-**Locations**:
-- `/home/home-server/Ensemble/lib/widgets/album_row.dart:89` - Fixed width of 150 + 12 margins = 162
-- `/home/home-server/Ensemble/lib/widgets/artist_row.dart:89` - Fixed width of 120 + 16 margins = 136
-
-**Fix**:
-```dart
-// Before:
-ListView.builder(
-  scrollDirection: Axis.horizontal,
-  itemCount: albums.length,
-  itemBuilder: ...
-
-// After:
-ListView.builder(
-  scrollDirection: Axis.horizontal,
-  itemCount: albums.length,
-  itemExtent: 162, // Width + margins
-  itemBuilder: ...
-```
-
-**Estimated Savings**: 10-15% improvement in horizontal scroll smoothness
-
----
-
-### QW-4: Add RepaintBoundary to List Tiles
-
-**Issue**: Artist list tiles in library screens lack RepaintBoundary, causing entire lists to repaint.
-
-**Impact**: Medium - RepaintBoundary isolates repaints to individual tiles.
-
-**Locations**:
-- `/home/home-server/Ensemble/lib/screens/library_artists_screen.dart:99-134` - Artist tiles
-- `/home/home-server/Ensemble/lib/screens/new_library_screen.dart` - Library artist tiles (around line 200)
-
-**Fix**:
-```dart
-Widget _buildArtistTile(...) {
-  return RepaintBoundary(
-    child: ListTile(
-      leading: CircleAvatar(...),
-      title: Text(...),
-      onTap: () {...},
-    ),
-  );
-}
-```
-
-**Estimated Savings**: 5-10% reduction in repaint overhead
-
----
-
-### QW-5: Fix Library Screen Hero Animations
-
-**Issue**: Library screen artist tiles are missing Hero widgets, breaking animations to ArtistDetailsScreen.
-
-**Impact**: High (UX) - Smooth hero animations are critical for premium feel.
-
-**Location**: `/home/home-server/Ensemble/lib/screens/new_library_screen.dart` (around lines 200-235)
-
-**Fix**: Wrap CircleAvatar and Text with Hero widgets matching ArtistDetailsScreen tags.
-
-```dart
-Widget _buildArtistTile(BuildContext context, Artist artist, MusicAssistantProvider provider) {
-  final imageUrl = provider.getImageUrl(artist, size: 128);
-  final suffix = '_library';
-
-  return ListTile(
-    leading: Hero(
-      tag: HeroTags.artistImage + (artist.uri ?? artist.itemId) + suffix,
-      child: CircleAvatar(
-        radius: 24,
-        backgroundImage: imageUrl != null ? NetworkImage(imageUrl) : null,
-      ),
-    ),
-    title: Hero(
-      tag: HeroTags.artistName + (artist.uri ?? artist.itemId) + suffix,
-      child: Material(
-        color: Colors.transparent,
-        child: Text(artist.name),
-      ),
-    ),
-    onTap: () {...},
-  );
-}
-```
-
-**Estimated Impact**: Eliminates jarring cross-fade, creates smooth morphing animation
-
----
-
-## Category 2: Widget Rebuild Optimization
-
-### WR-1: Replace context.watch() with context.select() in Lists
-
-**Issue**: Using context.watch<MusicAssistantProvider>() causes entire screen rebuilds when any provider property changes.
-
-**Impact**: High - Lists rebuild unnecessarily when unrelated state changes (e.g., playback state).
-
-**Locations**:
-- `/home/home-server/Ensemble/lib/screens/library_artists_screen.dart:13`
-- `/home/home-server/Ensemble/lib/screens/library_albums_screen.dart:12`
-- `/home/home-server/Ensemble/lib/screens/new_library_screen.dart:62`
-
-**Fix**:
-```dart
-// Before:
-final provider = context.watch<MusicAssistantProvider>();
-// Rebuilds when currentTrack, isPlaying, volume, etc. change
-
-// After:
-final artists = context.select<MusicAssistantProvider, List<Artist>>(
-  (p) => p.artists
-);
-final isLoading = context.select<MusicAssistantProvider, bool>(
-  (p) => p.isLoading
-);
-// Only rebuilds when artists or isLoading change
-```
-
-**Estimated Savings**: 30-50% reduction in unnecessary rebuilds
-
----
-
-### WR-2: Extract Static Widgets
-
-**Issue**: Static decoration widgets are recreated on every build.
-
-**Impact**: Medium - Flutter recreates identical widgets instead of reusing them.
-
-**Locations**: Throughout screens (Icons, Padding, SizedBox, etc.)
-
-**Fix**:
-```dart
-// Before:
-Icon(Icons.person_rounded, size: 60, color: colorScheme.onSurfaceVariant)
-
-// After:
-static const _placeholderIcon = Icon(Icons.person_rounded, size: 60);
-// Use colorScheme.onSurfaceVariant in IconTheme instead
-```
-
-**Estimated Savings**: 2-5% reduction in widget allocations
-
----
-
-### WR-3: Add const to BoxDecoration and TextStyle
-
-**Issue**: Decorations and styles are recreated on every build.
-
-**Impact**: Low-Medium - Small per-widget overhead that adds up in lists.
-
-**Fix**: Use const where colors are not dynamic, extract to constants file for reuse.
-
----
-
-## Category 3: Animation Improvements
-
-### AN-1: Optimize Hero Animation Curves
-
-**Issue**: FadeSlidePageRoute uses generic easeOut/easeIn curves.
-
-**Impact**: Medium - Better curves create more natural animations.
-
-**Location**: `/home/home-server/Ensemble/lib/utils/page_transitions.dart`
-
-**Recommendation**:
-```dart
-// Current:
-curve: Curves.easeOut,
-reverseCurve: Curves.easeIn,
-
-// Better for hero animations:
-curve: Curves.easeOutCubic,
-reverseCurve: Curves.easeInCubic,
-
-// Or match Material Design 3:
-curve: Curves.easeInOutCubicEmphasized,
-```
-
-**Note**: ExpandablePlayer already uses easeOutCubic/easeInCubic (good!)
-
----
-
-### AN-2: Reduce Overdraw with Transparent Backgrounds
-
-**Issue**: Some widgets have unnecessary background colors causing overdraw.
-
-**Impact**: Low - Minor GPU savings, more noticeable on older devices.
-
-**Recommendation**: Audit Material widgets for unnecessary color properties.
-
----
-
-### AN-3: Animation Disposal
-
-**Issue**: Verify all AnimationController instances are disposed.
-
-**Status**: ✅ Already handled correctly in ExpandablePlayer and GlobalPlayerOverlay
-
----
-
-## Category 4: List Performance
-
-### LP-1: Enable ListView.builder cacheExtent Tuning
-
-**Issue**: Default cacheExtent may not be optimal for music library browsing.
-
-**Impact**: Medium - Prebuilding items off-screen prevents scroll stutters.
-
-**Recommendation**:
-```dart
-ListView.builder(
-  cacheExtent: 500, // Prebuild ~500px off-screen
-  itemCount: items.length,
-  itemBuilder: ...
-)
-```
-
-**Note**: Test on device to find optimal value (300-1000px typical range).
-
----
-
-### LP-2: Lazy Load Images in Lists
-
-**Issue**: NetworkImage starts loading immediately, even for off-screen items.
-
-**Impact**: Low - Flutter already lazy-loads decoding, but could optimize further.
-
-**Current State**: ✅ Already using cacheWidth/cacheHeight (good!)
-
-**Optional Enhancement**: Use cached_network_image package for better caching.
-
----
-
-### LP-3: GridView childAspectRatio Precision
-
-**Issue**: GridView.builder uses childAspectRatio: 0.75, causing layout calculations.
-
-**Impact**: Very Low - Already efficient, no changes needed.
-
-**Status**: ✅ Current implementation is optimal
-
----
-
-## Category 5: State Restoration
-
-### SR-1: Preserve Scroll Positions
-
-**Issue**: Scroll positions are lost when navigating away and back to library screens.
-
-**Impact**: Medium (UX) - Users have to scroll back to where they were.
-
-**Locations**:
-- Library artists/albums/playlists tabs
-- Home screen rows
-
-**Fix**: Implement PageStorageKey for lists
-```dart
-ListView.builder(
-  key: const PageStorageKey<String>('artists_list'),
-  itemCount: items.length,
-  itemBuilder: ...
-)
-```
-
----
-
-### SR-2: Implement RestorationMixin for Tab State
-
-**Issue**: NewLibraryScreen tab selection is lost on app restart.
-
-**Impact**: Low (UX) - Minor annoyance, not performance-related.
-
-**Recommendation**: Add RestorationMixin to NewLibraryScreen state.
-
----
-
-## Performance Benchmarking Recommendations
-
-### Metrics to Track
-
-1. **Frame Rendering Time**: Should be <16ms (60fps) or <11ms (90fps on capable devices)
-2. **Jank Count**: Number of frames >16ms (target: <5% of frames)
-3. **Overdraw**: Use Flutter DevTools Performance Overlay
-4. **Widget Rebuild Count**: Use performance overlay to track rebuilds
-5. **Memory Usage**: Track during long scrolling sessions
-
-### Testing Scenarios
-
-1. **Scroll Performance Test**:
-   - Library with 1000+ albums
-   - Continuous fast scroll for 30 seconds
-   - Measure frame drops and jank count
-
-2. **Animation Smoothness Test**:
-   - Navigate Album → Details → Back 20 times rapidly
-   - Measure hero animation frame rate
-   - Check for stutter or dropped frames
-
-3. **Mini Player Expansion Test**:
-   - Expand/collapse player 20 times
-   - Measure animation consistency
-   - Check for layout jank
-
-4. **Concurrent Operations Test**:
-   - Play music while scrolling library
-   - Navigate between screens during playback
-   - Ensure no frame drops during animations
-

-## Detailed Changes by Phase
-
-### Phase 1: Quick Wins (Critical Priority)
-
-#### ✅ QW-1: Added `const` Constructors
-**Impact**: High - 5-10% reduction in widget rebuilds
-
-**Changes**:
-- `LibraryArtistsScreen`: Added `const` constructor
-- `LibraryAlbumsScreen`: Added `const` constructor
-- All stateless widgets now use const constructors where applicable
-
-**Code Example**:
-```dart
-// Before:
-class LibraryArtistsScreen extends StatelessWidget {
-  LibraryArtistsScreen({super.key});
-
-// After:
-class LibraryArtistsScreen extends StatelessWidget {
-  const LibraryArtistsScreen({super.key});
-```
-
----
-
-#### ✅ QW-2: Added Keys to List Items
-**Impact**: High - 15-25% reduction in list scroll jank
-
-**Changes**:
-- Added `ValueKey` to all list items in:
-  - `library_artists_screen.dart` (line 104)
-  - `library_albums_screen.dart` (line 99)
-  - `new_library_screen.dart` (artists: line 212, albums: line 319)
-  - `album_row.dart` (line 97)
-  - `artist_row.dart` (line 97)
-
-**Code Example**:
-```dart
-return AlbumCard(
-  key: ValueKey(album.uri ?? album.itemId),
-  album: album,
-  heroTagSuffix: 'library',
-);
-```
-
----
-
-#### ✅ QW-3: Added itemExtent to Horizontal Lists
-**Impact**: Medium - 10-15% improvement in horizontal scroll smoothness
-
-**Changes**:
-- `album_row.dart`: Added `itemExtent: 162` (150px width + 12px margins)
-- `artist_row.dart`: Added `itemExtent: 136` (120px width + 16px margins)
-
-**Code Example**:
-```dart
-ListView.builder(
-  scrollDirection: Axis.horizontal,
-  itemCount: albums.length,
-  itemExtent: 162, // Width + margins
-  itemBuilder: ...
-)
-```
-
----
-
-#### ✅ QW-4: Added RepaintBoundary to List Tiles
-**Impact**: Medium - 5-10% reduction in repaint overhead
-
-**Changes**:
-- Wrapped artist list tiles with `RepaintBoundary`:
-  - `library_artists_screen.dart` (line 122)
-  - `new_library_screen.dart` (line 220)
-
-**Code Example**:
-```dart
-Widget _buildArtistTile(...) {
-  return RepaintBoundary(
-    child: ListTile(
-      // ListTile content
-    ),
-  );
-}
-```
-
----
-
-#### ✅ QW-5: Fixed Library Screen Hero Animations
-**Impact**: High (UX) - Eliminates jarring transitions, creates smooth morphing
-
-**Changes**:
-- Added Hero widgets to artist tiles in `new_library_screen.dart`:
-  - Hero tag for CircleAvatar (artist image)
-  - Hero tag for Text (artist name) with Material wrapper
-  - Tags match the format in `ArtistDetailsScreen`
-
-**Code Example**:
-```dart
-leading: Hero(
-  tag: HeroTags.artistImage + (artist.uri ?? artist.itemId) + '_library',
-  child: CircleAvatar(...)
-),
-title: Hero(
-  tag: HeroTags.artistName + (artist.uri ?? artist.itemId) + '_library',
-  child: Material(
-    color: Colors.transparent,
-    child: Text(artist.name),
-  ),
-)
-```
-
----
-
-### Phase 2: Widget Rebuild Optimization (High Priority)
-
-#### ✅ WR-1: Replaced context.watch() with Selector
-**Impact**: High - 30-50% reduction in unnecessary rebuilds
-
-**Changes**:
-- `library_artists_screen.dart`: Uses `Selector<MusicAssistantProvider, (List<Artist>, bool)>` to only rebuild when artists or loading state changes
-- `library_albums_screen.dart`: Uses `Selector<MusicAssistantProvider, (List<Album>, bool)>` to only rebuild when albums or loading state changes
-- `new_library_screen.dart`:
-  - Main build uses `Selector<MusicAssistantProvider, bool>` for connection state
-  - Artists tab uses `Selector` for (artists, isLoading)
-  - Albums tab uses `Selector` for (albums, isLoading)
-
-**Benefit**: Previously, these widgets rebuilt on ANY provider change (playback state, volume, current track, etc.). Now they only rebuild when their specific data changes.
-
-**Code Example**:
-```dart
-// Before:
-final provider = context.watch<MusicAssistantProvider>();
-// Rebuilds when currentTrack, isPlaying, volume, etc. change
-
-// After:
-Selector<MusicAssistantProvider, (List<Artist>, bool)>(
-  selector: (_, provider) => (provider.artists, provider.isLoading),
-  builder: (context, data, _) {
-    final (artists, isLoading) = data;
-    // Only rebuilds when artists or isLoading change
-  },
-)
-```
-
----
-
-#### ✅ WR-2: Converted to context.read() Where Appropriate
-**Impact**: Medium - Eliminates unnecessary widget subscriptions
-
-**Changes**:
-- Replaced `provider.loadLibrary()` with `context.read<MusicAssistantProvider>().loadLibrary()` in callbacks
-- Used `context.read()` in `_buildArtistTile()` and `_buildPlaylistTile()` methods
-
-**Benefit**: Prevents these methods from subscribing to provider changes when they only need one-time access.
-
----
-
-### Phase 3: Animation Improvements (High Priority)
-
-#### ✅ AN-1: Optimized Hero Animation Curves
-**Impact**: Medium - Noticeably smoother and more natural animations
-
-**Changes**:
-- `page_transitions.dart`: Updated all animation curves:
-  - `Curves.easeOut` → `Curves.easeOutCubic`
-  - `Curves.easeIn` → `Curves.easeInCubic`
-
-**Benefit**: Cubic curves provide more natural, premium-feeling motion that better matches Material Design 3 guidelines and apps like Symphonium.
-
-**Code Example**:
-```dart
-// Before:
-curve: Curves.easeOut,
-reverseCurve: Curves.easeIn,
-
-// After:
-curve: Curves.easeOutCubic,
-reverseCurve: Curves.easeInCubic,
-```
-
----
-
-### Phase 4: List Performance (Medium Priority)
-
-#### ✅ LP-1: Added cacheExtent Tuning
-**Impact**: Medium - 10-15% improvement in large list scroll performance
-
-**Changes**:
-- Added `cacheExtent: 500` to all ListViews and GridViews:
-  - `library_artists_screen.dart`
-  - `library_albums_screen.dart`
-  - `new_library_screen.dart` (all 3 tabs)
-
-**Benefit**: Prebuilds items ~500px off-screen, preventing scroll stutters when items come into view.
-
-**Code Example**:
-```dart
-ListView.builder(
-  cacheExtent: 500, // Prebuild items off-screen for smoother scrolling
-  itemCount: items.length,
-  itemBuilder: ...
-)
-```
-
----
-
-### Phase 5: State Restoration (Low Priority - UX Polish)
-
-#### ✅ SR-1: Added PageStorageKey to All Lists
-**Impact**: Medium (UX) - Users no longer lose scroll position
-
-**Changes**:
-- Added unique `PageStorageKey<String>` to all scrollable lists:
-  - `library_artists_full_list`
-  - `library_albums_full_grid`
-  - `library_artists_list` (in NewLibraryScreen)
-  - `library_albums_grid` (in NewLibraryScreen)
-  - `library_playlists_list`
-
-**Benefit**: Scroll positions are now preserved when navigating away and back to library screens.
-
-**Code Example**:
-```dart
-ListView.builder(
-  key: const PageStorageKey<String>('library_artists_list'),
-  itemCount: items.length,
-  itemBuilder: ...
-)
-```
-

-
-#### 1. Scroll Performance Test
-- **Test**: Library with 1000+ albums
-- **Action**: Continuous fast scroll for 30 seconds
-- **Measure**: Frame drops and jank count using Flutter DevTools
-- **Expected**: <5% jank rate
-
-#### 2. Animation Smoothness Test
-- **Test**: Navigate Album → Details → Back 20 times rapidly
-- **Measure**: Hero animation frame rate
-- **Expected**: Consistent 60fps, no visible stutter
-
-#### 3. Mini Player Test
-- **Test**: Expand/collapse mini player 20 times
-- **Measure**: Animation consistency
-- **Expected**: Smooth 60fps animation
-
-#### 4. Concurrent Operations Test
-- **Test**: Play music while scrolling library
-- **Action**: Navigate between screens during playback
-- **Expected**: No frame drops during animations
-
-#### 5. State Restoration Test
-- **Test**: Scroll to middle of artist list
-- **Action**: Navigate away and back
-- **Expected**: Scroll position preserved
-
-### Performance Profiling Tools
-
-Run the app with:
-```bash
-flutter run --profile
-```
-
-Enable performance overlay:
-```bash
-flutter run --profile --enable-software-rendering
-```
-
-Use Flutter DevTools:
-- Timeline profiler to identify frame drops
-- Performance overlay to visualize rebuilds
-- Memory profiler to check for leaks

-|--------|-----------|-----------------|-----------------|
-| Frame Time (avg) | <12ms | ~18-20ms (est) | <14ms |
-| Jank Rate | <3% | ~15-20% (est) | <5% |
-| Hero Animation | Silky smooth | Occasional stutter | Smooth 60fps |
-| List Scroll | Buttery smooth | Minor jank | Smooth 60fps |
-| Rebuild Count | Minimal | Excessive | Targeted |
-
----
-
-## Implementation Notes
-
-### What Worked Well
-1. **Selector Pattern**: Massive improvement over context.watch() - dramatically reduced unnecessary rebuilds
-2. **List Item Keys**: Essential for Flutter's diffing algorithm to work efficiently
-3. **itemExtent**: Simple change with big impact on horizontal lists
-4. **Cubic Curves**: Subtle but makes animations feel more premium
-
-### Lessons Learned
-1. Always use Selector when only watching specific provider properties
-2. Keys are critical for list performance, not optional
-3. RepaintBoundary should be standard practice for list items
-4. cacheExtent is a powerful tool for large lists
-
-### Best Practices Applied
-- ✅ RepaintBoundary for expensive widgets
-- ✅ const constructors everywhere possible
-- ✅ Keys on all list items
-- ✅ Targeted rebuilds with Selector
-- ✅ Proper animation curves
-- ✅ State restoration for better UX
-- ✅ Cache extent for smooth scrolling
-
----
-
-## Next Steps (Future Optimizations)
-
-While all audit items are implemented, consider these future enhancements:
-
-### Low Priority Improvements
-1. **Tab State Restoration**: Implement RestorationMixin for NewLibraryScreen to remember selected tab (SR-2 from audit)
-2. **Cached Network Images**: Consider `cached_network_image` package for better image caching
-3. **Virtual Scrolling**: For extremely large libraries (>5000 items), consider implementing virtual scrolling
-
-### Monitoring
-1. Add fps_monitor package for production performance tracking
-2. Set up performance benchmarks in CI/CD
-3. Create automated performance regression tests

+# Audiobooks Integration - Implementation Plan
+
+## Overview
+
+Add audiobook support to Ensemble with automatic user profile separation based on Music Assistant authentication. Includes local database for performance caching and per-user data isolation.
+
+---
+
+## Phase 1: Database Foundation
+
+**Goal:** Add persistent local storage layer using Drift (SQLite)
+
+### Tasks
+- [ ] Add Drift package dependencies (`drift`, `drift_flutter`, `path_provider`)
+- [ ] Create database class with schema version management
+- [ ] Create `profiles` table:
+  ```dart
+  class Profiles extends Table {
+    TextColumn get username => text()();  // MA username (primary key)
+    TextColumn get displayName => text().nullable()();
+    TextColumn get source => text()();  // 'ma_auth' or 'manual'
+    DateTimeColumn get createdAt => dateTime()();
+    BoolColumn get isActive => boolean().withDefault(const Constant(false))();
+  }
+  ```
+- [ ] Create `recently_played` table:
+  ```dart
+  class RecentlyPlayed extends Table {
+    IntColumn get id => integer().autoIncrement()();
+    TextColumn get profileUsername => text().references(Profiles, #username)();
+    TextColumn get mediaId => text()();
+    TextColumn get mediaType => text()();  // 'track', 'album', 'artist', 'audiobook'
+    TextColumn get name => text()();
+    TextColumn get artist => text().nullable()();
+    TextColumn get imageUrl => text().nullable()();
+    DateTimeColumn get playedAt => dateTime()();
+  }
+  ```
+- [ ] Create `library_cache` table for albums/artists/audiobooks
+- [ ] Generate Drift code (`dart run build_runner build`)
+- [ ] Create `DatabaseService` singleton with initialization
+
+### Acceptance Criteria
+- Database initializes on app startup
+- Schema migrations work correctly
+- CRUD operations functional for all tables
+
+---
+
+## Phase 2: Profile System
+
+**Goal:** Auto-create and manage user profiles based on MA authentication
+
+### Tasks
+- [ ] Create `ProfileService` class
+- [ ] On MA login success: check if profile exists for username
+  - If not, create new profile with `displayName` from MA user info
+  - Set as active profile
+- [ ] On manual name entry (no-auth): create/select profile by entered name
+- [ ] Add `getCurrentProfile()` method
+- [ ] Migrate existing `ownerName` to profile on first launch post-update
+- [ ] Add profile indicator to settings screen (show current profile name)
+
+### Acceptance Criteria
+- Profile auto-created on first login
+- Correct profile selected on subsequent logins
+- Existing users migrated seamlessly
+
+---
+
+## Phase 3: Recently Played Migration
+
+**Goal:** Move recently played from memory cache to database, scoped by profile
+
+### Tasks

+# Per-Provider Sync Implementation
+
+## Date: January 17, 2026
+
+## Overview
+
+This document details the implementation of per-provider sync with source tracking, enabling instant client-side filtering that properly differentiates between multiple accounts of the same provider type (e.g., two different Spotify accounts).
+
+## Problem Statement
+
+### The Core Issue
+
+When a user has multiple accounts of the same provider type (e.g., two Spotify accounts: "Chris Laycock" and "Bababagoly"), the existing provider filter couldn't differentiate between them.
+
+**Why?** Music Assistant's `provider_mappings` field on media items shows which providers **CAN PLAY** an item, not which provider **ADDED** it. When both Spotify accounts can play the same artist, both appear in `provider_mappings`, making client-side filtering impossible.
+
+### Previous Approach (Failed)
+
+The initial implementation tried to filter client-side using `provider_mappings`:
+
+```dart
+bool isItemAllowedByProviderFilter(MediaItem item) {
+  final mappings = item.providerMappings;
+  for (final mapping in mappings) {
+    if (_providerFilter.contains(mapping.providerInstance)) {
+      return true;
+    }
+  }
+  return false;
+}
+```
+
+**Result:** Both Spotify accounts showed the same items because `provider_mappings` contained both account IDs for shared content.
+
+### Race Condition Issue
+
+Additionally, when rapidly toggling providers, a race condition occurred:
+1. User toggles Provider A off
+2. Sync starts for remaining providers
+3. User toggles Provider B off before sync completes
+4. First sync completes with wrong filter state
+5. UI shows incorrect results
+
+## Solution: Per-Provider Sync with Source Tracking
+
+### Concept
+
+Instead of relying on `provider_mappings`, we:
+1. **Sync each provider separately** using the MA API's `provider` parameter
+2. **Tag each item** with which provider instance(s) returned it
+3. **Store source tracking** in the local database
+4. **Filter client-side** using the source tracking data (instant)
+5. **Background sync** keeps data fresh without blocking UI
+
+### Why This Works
+
+When we call the MA API with `provider: ["spotify--RKnr3jKx"]`, the server returns **only items from that specific account's library**. By syncing each provider separately and remembering which provider returned each item, we can accurately filter.
+
+## Implementation Details
+
+### 1. Database Schema Update
+
+**File:** `lib/database/database.dart`
+
+Added `sourceProviders` column to `LibraryCache` table:
+
+```dart
+class LibraryCache extends Table {
+  // ... existing columns ...
+
+  /// Provider instance IDs that provided this item (JSON array)
+  /// Used for client-side filtering by source provider
+  TextColumn get sourceProviders => text().withDefault(const Constant('[]'))();
+}
+```
+
+**Schema version:** 5 → 6
+
+**Migration:**
+```dart
+if (from < 6) {
+  await customStatement(
+    "ALTER TABLE library_cache ADD COLUMN source_providers TEXT NOT NULL DEFAULT '[]'"
+  );
+}
+```
+
+### 2. Database Service Updates
+
+**File:** `lib/services/database_service.dart`
+
+Added `sourceProvider` parameter to `cacheItem()`:
+
+```dart
+Future<void> cacheItem<T>({
+  required String itemType,
+  required String itemId,
+  required Map<String, dynamic> data,
+  String? sourceProvider,  // NEW: tracks which provider this item came from
+})
+```
+
+Added new method to retrieve items with source tracking:
+
+```dart
+Future<List<(Map<String, dynamic>, List<String>)>> getCachedItemsWithProviders(String itemType)
+```
+
+Returns tuples of `(itemData, sourceProviderIds)`.
+
+### 3. SyncService Rewrite
+
+**File:** `lib/services/sync_service.dart`
+
+#### New Fields
+
+```dart
+// Source provider tracking for client-side filtering
+Map<String, List<String>> _albumSourceProviders = {};
+Map<String, List<String>> _artistSourceProviders = {};
+Map<String, List<String>> _audiobookSourceProviders = {};
+Map<String, List<String>> _playlistSourceProviders = {};
+```
+
+#### Per-Provider Sync Logic
+
+```dart
+Future<void> syncFromApi(MusicAssistantAPI api, {
+  bool force = false,
+  List<String>? providerInstanceIds,
+}) async {
+  // If specific providers are requested, sync each separately
+  if (providerInstanceIds != null && providerInstanceIds.isNotEmpty) {
+    for (final providerId in providerInstanceIds) {
+      // Fetch from this specific provider
+      final results = await Future.wait([
+        api.getAlbums(limit: 1000, providerInstanceIds: [providerId]),
+        api.getArtists(limit: 1000, providerInstanceIds: [providerId]),
+        // ... etc
+      ]);
+
+      // Track source provider for each item
+      for (final album in albums) {
+        albumMap[album.itemId] = album;
+        _albumSourceProviders.putIfAbsent(album.itemId, () => []);
+        if (!_albumSourceProviders[album.itemId]!.contains(providerId)) {
+          _albumSourceProviders[album.itemId]!.add(providerId);
+        }
+      }
+    }
+  }
+}
+```
+
+#### Client-Side Filtering Methods
+
+```dart
+/// Filter albums by source provider (instant, no network)
+List<Album> getAlbumsFilteredByProviders(Set<String> enabledProviderIds) {
+  if (enabledProviderIds.isEmpty || _albumSourceProviders.isEmpty) {
+    return _cachedAlbums;
+  }
+  return _cachedAlbums.where((album) {
+    final sources = _albumSourceProviders[album.itemId];
+    if (sources == null || sources.isEmpty) return true; // No tracking = show
+    return sources.any((s) => enabledProviderIds.contains(s));
+  }).toList();
+}
+
+// Similar methods for artists, audiobooks, playlists
+```
+
+### 4. Library Screen Updates
+
+**File:** `lib/screens/new_library_screen.dart`
+
+#### Hybrid Provider Toggle Handler
+
+```dart
+void _handleProviderToggle(String providerId, bool enabled) {
+  final maProvider = context.read<MusicAssistantProvider>();
+
+  // Instant UI update via global provider toggle
+  maProvider.toggleProviderEnabled(providerId, enabled);
+  setState(() {}); // Rebuild with client-side filtering
+
+  // Background sync after 1.5s debounce
+  _providerFilterDebounce?.cancel();
+  _providerFilterDebounce = Timer(const Duration(milliseconds: 1500), () async {
+    if (mounted) {
+      await maProvider.forceLibrarySync();
+      if (mounted) setState(() {});
+    }
+  });
+}
+```
+
+#### Updated Tab Builders
+
+Artists tab now uses source tracking:
+
+```dart
+Widget _buildArtistsTab(BuildContext context, S l10n) {
+  return Selector<MusicAssistantProvider, (List<Artist>, bool, Set<String>)>(
+    selector: (_, provider) => (
+      provider.artists,
+      provider.isLoading,
+      provider.enabledProviderIds.toSet()
+    ),
+    builder: (context, data, _) {
+      final (allArtists, isLoading, enabledProviders) = data;
+
+      // Client-side filtering using SyncService source tracking
+      final syncService = SyncService.instance;
+      final filteredArtists = syncService.hasSourceTracking && enabledProviders.isNotEmpty
+          ? syncService.getArtistsFilteredByProviders(enabledProviders)
+          : allArtists;
+
+      // ... rest of build
+    },
+  );
+}
+```
+
+Similar updates for albums, playlists, and audiobooks tabs.
+
+### 5. Provider Instance Model
+
+**File:** `lib/models/provider_instance.dart` (new file)
+
+```dart
+class ProviderInstance {
+  final String instanceId;  // e.g., "spotify--abc123"
+  final String domain;      // e.g., "spotify"
+  final String name;        // e.g., "Spotify (John's Account)"
+  final bool available;
+
+  /// Known music provider domains
+  static const Set<String> musicProviderDomains = {
+    'spotify', 'tidal', 'qobuz', 'deezer', 'ytmusic', 'soundcloud',
+    'apple_music', 'amazon_music', 'plex', 'subsonic', 'opensubsonic',
+    'jellyfin', 'emby', 'navidrome', 'audiobookshelf', 'filesystem',
+    'tunein', 'radiobrowser', 'snapcast', 'fully_kiosk',
+  };
+
+  bool get isMusicProvider => musicProviderDomains.contains(domain);
+}
+```
+

+## Files Changed
+
+| File | Changes |
+|------|---------|
+| `lib/database/database.dart` | Added `sourceProviders` column, schema v6, migration |
+| `lib/database/database.g.dart` | Auto-generated from schema changes |
+| `lib/services/database_service.dart` | Added `sourceProvider` param, `getCachedItemsWithProviders()` |
+| `lib/services/sync_service.dart` | Per-provider sync, source tracking maps, filtering methods |

+
+## Testing Checklist
+
+- [ ] Fresh install: First sync should populate source tracking
+- [ ] Toggle single provider: UI updates instantly
+- [ ] Toggle multiple providers rapidly: Debounce prevents race conditions
+- [ ] Two Spotify accounts: Toggling one only shows that account's items
+- [ ] Mixed providers: Toggling Spotify doesn't affect Audiobookshelf items
+- [ ] Legacy cache: Items without source tracking show regardless of filter
+- [ ] Pull to refresh: Refreshes source tracking data
+
+## Known Limitations
+
+1. **First sync required:** Source tracking only works after at least one sync with providers enabled
+2. **Network cost:** Per-provider sync makes N API calls (one per provider) vs. 1 call for all providers
+3. **Items in multiple accounts:** If the same item exists in both Spotify accounts, it will show when either is enabled
+
+## Future Improvements
+
+1. **Incremental sync:** Only sync changed items instead of full library
+2. **Provider-specific cache age:** Different sync intervals per provider
+3. **Offline source tracking:** Persist source tracking independently of full cache
+
+## Branch
+
+All changes are on the `feature/per-provider-sync` branch.
+
+```bash
+git checkout feature/per-provider-sync
+```
+
+## Commit

+# Provider Filter Implementation Notes
+
+## Overview
+
+This document captures the context and learnings from an attempted implementation of provider filtering in the Ensemble app. The goal was to allow users to filter their library to show only items from a specific music provider (e.g., only one Spotify account when multiple are configured).
+
+## The Problem
+
+Users with multiple music provider accounts (e.g., two Spotify accounts: one personal, one family) want to filter their library view to show only items from one specific account. The Music Assistant (MA) web UI successfully implements this feature.
+
+## What Works vs What Failed
+
+### Works: Different Provider Types
+Filtering between different provider types (e.g., Spotify vs Tidal vs Plex) works correctly. Each provider type has distinct `provider_mappings` entries.
+
+### Failed: Multiple Accounts of Same Provider
+Filtering between multiple Spotify accounts (e.g., `spotify--abc123` vs `spotify--xyz789`) does NOT work correctly. The same library items appear regardless of which Spotify account is selected.
+
+## Root Cause Analysis
+
+### The provider_mappings Problem
+
+MA's `provider_mappings` field on media items does NOT indicate "which account ADDED this item to the library." Instead, it indicates "which providers CAN PLAY this item."
+
+Example: An artist "Ari Mason" that exists ONLY in User A's Spotify library will show provider_mappings containing BOTH Spotify accounts:
+```json
+{
+  "provider_mappings": [
+    {"provider_instance": "spotify--userA_id", "item_id": "..."},
+    {"provider_instance": "spotify--userB_id", "item_id": "..."}
+  ]
+}
+```
+
+This happens because:
+1. MA's internal database stores that the artist exists
+2. MA knows both Spotify accounts CAN play this artist (Spotify has the content)
+3. MA doesn't track WHICH account originally added the item to the library
+
+### MA Web UI Behavior
+
+The MA web UI's provider filter works differently - it appears to use server-side filtering via the `provider` parameter on library_items API calls. When you select a single provider in MA settings, the API returns only items from that provider's library.
+
+## API Investigation
+
+### Server-Side Filtering Parameter
+
+The MA server's `library_items` method accepts a `provider` parameter:
+- Parameter name: `provider` (string or list of strings)
+- Endpoint: `music/{type}/library_items` (e.g., `music/artists/library_items`)
+- Expected behavior: Filter to only return items from the specified provider's library
+
+### What We Tried
+
+1. **Client-side filtering based on provider_mappings**
+   - Result: Failed - all Spotify accounts appear in mappings regardless of which added the item
+
+2. **Server-side filtering with `provider` parameter**
+   - Result: Partially implemented but behavior was inconsistent
+   - The API accepts the parameter but may not filter correctly for same-provider-type accounts
+
+3. **Using `provider_instance_id_or_domain` parameter**
+   - Result: This parameter is for getting specific items by ID, not for filtering library_items
+
+## Code Locations
+
+### Files Modified (in stash)
+
+The implementation attempt is preserved in git stash:
+```bash
+git stash list  # Look for "provider-filter-and-dropdown-work"
+git stash show -p stash@{0}  # View the changes
+```
+
+Key files that were modified:
+
+1. **lib/providers/music_assistant_provider.dart**
+   - `_disabledProviders`: List of disabled provider instance IDs (local app setting)
+   - `selectedProviderForFilter`: Returns single enabled provider for server-side filtering
+   - `toggleProviderEnabled()`: Toggle provider on/off and trigger re-sync
+   - `loadDisabledProviders()`: Load from local settings
+   - `filterByProvider()`: Client-side filtering (enhanced version)
+   - `isItemAllowedByProviderFilter()`: Check if item should be visible
+
+2. **lib/services/music_assistant_api.dart**
+   - Added `provider` parameter to: `getArtists`, `getAlbums`, `getTracks`, `getRandomArtists`, `getRandomAlbums`
+   - Added `MusicProvider` model parsing from `/providers` endpoint
+   - `musicProviders` getter: List of available music providers
+
+3. **lib/services/sync_service.dart**
+   - Added `provider` parameter to `syncFromApi()` and `forceSync()`
+   - Pass provider filter to API calls during sync
+
+4. **lib/services/settings_service.dart**
+   - `getDisabledMusicProviders()`: Get list of disabled provider IDs
+   - `setDisabledMusicProviders()`: Save disabled providers
+   - `toggleProviderEnabled()`: Toggle and persist
+
+5. **lib/screens/settings_screen.dart**
+   - UI for toggling individual providers on/off
+   - Display provider name and instance ID
+
+6. **lib/screens/new_library_screen.dart**
+   - Integration with provider filtering
+
+7. **lib/models/music_provider.dart** (new file)
+   - Model for MA provider instances
+   - Fields: `instanceId`, `domain`, `name`, `available`
+
+## Race Condition Issue
+
+A race condition was identified where:
+1. Initial app sync starts WITHOUT provider filter
+2. User toggles provider filter
+3. `clearCache()` is called
+4. New sync with provider filter tries to start
+5. "Sync already in progress" - new sync is skipped
+6. Result: Old unfiltered data remains
+
+Fix attempted: Reset `_isSyncing = false` in `clearCache()` to allow fresh sync.
+
+## Potential Solutions to Explore
+
+### 1. Investigate MA Server-Side Filtering
+
+The MA server should support filtering by provider. Need to verify:
+- Does the `provider` parameter work for filtering between same-type providers?
+- Is there a different parameter or API endpoint?
+- Check MA source code: https://github.com/music-assistant/server
+
+### 2. Library Sync Per Provider
+
+Instead of syncing all items and filtering, sync each provider's library separately:
+```dart
+for (final provider in enabledProviders) {
+  final items = await api.getAlbums(provider: provider.instanceId);
+  // Store with provider association
+}
+```
+
+### 3. Track Item Origin
+
+Store which provider originally added each item:
+- Modify database schema to track `source_provider`
+- When syncing, record which provider the item came from
+- Filter based on source, not playability
+
+### 4. Use MA's Internal Library State
+
+MA might have internal state about which items are in which provider's library. Investigate:
+- `/music/library/items` endpoint
+- Provider-specific library endpoints
+- MA's database schema for library associations
+
+### 5. Check MA User Settings
+
+The MA web UI's provider filter might be stored in user settings:
+```dart
+final userInfo = await api.getCurrentUserInfo();
+// Check for provider_filter or similar field
+```
+
+## Testing Notes
+
+### Log Messages to Watch
+
+```
+🔌 Selected provider for filter: spotify--xxxxx
+🔍 API getArtists args: {limit: 1000, provider: spotify--xxxxx}
+🔍 API getArtists returned XXX items
+🔌 filterByProvider: XXX → YYY (disabled=[...])
+```
+
+### Test Scenario
+
+1. Configure two Spotify accounts in MA
+2. Add different artists to each account's library
+3. In Ensemble, select only one Spotify account
+4. Verify library shows ONLY that account's items
+5. Switch to other account, verify different items
+
+### Expected vs Actual
+
+- **Expected**: Artist "Ari Mason" (only in Account A) should NOT appear when Account B is selected
+- **Actual**: Artist appears regardless of which account is selected
+

+
+### Relevant MA Source Files
+
+- `music_assistant/server/controllers/music.py` - Library item retrieval
+- `music_assistant/server/models/provider.py` - Provider model
+- `music_assistant/server/providers/` - Individual provider implementations
+
+## Conclusion
+
+The core challenge is that MA's `provider_mappings` indicates playability, not ownership. Server-side filtering via the `provider` parameter should work but needs further investigation to understand why it doesn't differentiate between multiple accounts of the same provider type.
+
+The implementation is preserved in the git stash for future reference. The sorting/dropdown improvements were extracted and committed separately.

+# Audiobook Provider Filtering Fix
+
+## Date: January 17, 2026 (Continuation)
+
+## Overview
+
+This session focused on fixing provider filtering issues discovered after the initial provider filtering improvements:
+1. Audiobooks were not responding to provider filter changes (browse API ignoring `providerInstanceIds`)
+2. UI not updating instantly when toggling providers (missing `notifyListeners()` call)
+3. Audiobook tabs not rebuilding on provider changes (using `context.read` instead of `Selector`)
+
+---
+
+## Problem Statement
+
+After implementing capability-based provider filtering for the music library, two issues remained:
+
+### Issue 1: Audiobooks Not Filtering During Sync
+
+The bug report showed:
+```
+📊 Source tracking: 252 albums, 87 artists have provider info
+📚 Total audiobooks from browse: 186
+```
+
+- Albums and artists had provider source tracking
+- Audiobooks had NO provider source tracking (not listed)
+- All 186 audiobooks were returned regardless of provider selection
+
+### Issue 2: UI Not Updating Instantly
+
+When toggling providers in the library menu:
+- Music tabs weren't updating immediately
+- Audiobooks required manual pull-to-refresh
+- Changes only appeared after ~600ms (debounce timer)
+
+---
+
+## Root Cause Analysis
+
+### Cause 1: Browse API Ignoring Provider Filter
+
+In `lib/services/music_assistant_api.dart`, when ABS library filtering is enabled, the `getAudiobooks()` function uses the browse API but was **ignoring** the `providerInstanceIds` parameter:
+
+```dart
+// BEFORE: providerInstanceIds was ignored when using browse API
+if (enabledLibraries != null && enabledLibraries.isNotEmpty) {
+  return await _getAudiobooksFromBrowse(enabledLibraries, favoriteOnly: favoriteOnly);
+}
+```
+
+### Cause 2: `notifyListeners()` Called Too Late
+
+In `lib/providers/music_assistant_provider.dart`, the `toggleProviderEnabled()` function only called `notifyListeners()` **inside** the 600ms debounce timer:
+
+```dart
+// BEFORE: notifyListeners only called after 600ms debounce
+_providerFilterDebounceTimer = Timer(const Duration(milliseconds: 600), () {
+  forceLibrarySync();
+  notifyListeners();  // Too late! UI should update immediately
+});
+```
+
+### Cause 3: Audiobook Tabs Not Listening for Changes
+
+The audiobook tabs used `context.read<MusicAssistantProvider>()` which doesn't trigger rebuilds when the provider changes:
+
+```dart
+// BEFORE: context.read doesn't listen for changes
+Widget _buildBooksAuthorsTab(BuildContext context, S l10n) {
+  final maProvider = context.read<MusicAssistantProvider>();
+  final enabledProviders = maProvider.enabledProviderIds.toSet();
+  // ... widget doesn't rebuild when enabledProviders changes
+}
+```
+
+---
+
+## Solutions
+
+### Fix 1: Browse API Provider Filtering
+
+**File:** `lib/services/music_assistant_api.dart` (lines 760-785)
+
+Added logic to filter library paths by provider ID before browsing:
+
+```dart
+if (enabledLibraries != null && enabledLibraries.isNotEmpty) {
+  _logger.log('📚 getAudiobooks: enabledLibraries=$enabledLibraries, providerInstanceIds=$providerInstanceIds');
+
+  // If specific providers are requested, filter libraries to only matching providers
+  // Library paths start with provider ID (e.g., "audiobookshelf--abc123://lb...")
+  var librariesToBrowse = enabledLibraries;
+  if (providerInstanceIds != null && providerInstanceIds.isNotEmpty) {
+    librariesToBrowse = enabledLibraries.where((libPath) {
+      // Extract provider ID from library path (everything before "://")
+      final providerEnd = libPath.indexOf('://');
+      if (providerEnd == -1) return false;
+      final providerId = libPath.substring(0, providerEnd);
+      return providerInstanceIds.contains(providerId);
+    }).toList();
+
+    // If no libraries match the requested providers, return empty
+    if (librariesToBrowse.isEmpty) {
+      return [];
+    }
+  }
+  return await _getAudiobooksFromBrowse(librariesToBrowse, favoriteOnly: favoriteOnly);
+}
+```
+
+### Fix 2: Immediate `notifyListeners()` Call
+
+**File:** `lib/providers/music_assistant_provider.dart` (line 1149)
+
+Moved `notifyListeners()` to fire immediately after `_enabledProviderIds` changes:
+
+```dart
+// Reload the enabled providers
+final savedEnabled = await SettingsService.getEnabledMusicProviders();
+_enabledProviderIds = savedEnabled ?? [];
+
+// Notify listeners IMMEDIATELY so UI rebuilds with client-side filtering
+// This enables instant UI updates using cached data with source tracking
+notifyListeners();
+
+// Cancel any pending debounce timer
+_providerFilterDebounceTimer?.cancel();
+
+// Start debounced sync - waits 600ms for user to finish toggling
+// This refreshes the cache with new data from enabled providers
+_providerFilterDebounceTimer = Timer(const Duration(milliseconds: 600), () {
+  _logger.log('🔄 Debounce complete, starting library sync...');
+  forceLibrarySync();
+});
+```
+
+### Fix 3: Audiobook Tabs Use Selector
+
+**File:** `lib/screens/new_library_screen.dart`
+
+Wrapped `_buildBooksAuthorsTab` and `_buildAllBooksTab` in `Selector` to rebuild when `enabledProviderIds` changes:
+
+```dart
+Widget _buildBooksAuthorsTab(BuildContext context, S l10n) {
+  // Use Selector to rebuild when enabledProviderIds changes
+  return Selector<MusicAssistantProvider, Set<String>>(
+    selector: (_, provider) => provider.enabledProviderIds.toSet(),
+    builder: (context, enabledProviders, _) {
+      final syncService = SyncService.instance;
+
+      // Client-side filtering using SyncService source tracking for instant updates
+      var audiobooks = syncService.hasSourceTracking && enabledProviders.isNotEmpty
+          ? syncService.getAudiobooksFilteredByProviders(enabledProviders)
+          : List<Audiobook>.from(_audiobooks);
+
+      // ... rest of widget
+    },
+  );
+}
+```
+
+### Fix 4: Enhanced Sync Logging
+
+**File:** `lib/services/sync_service.dart`
+
+Added audiobook counts to logging:
+
+```dart
+// Per-provider log (line 237)
+_logger.log('  📥 Got ${albums.length} albums, ${artists.length} artists, ${audiobooks.length} audiobooks from $providerId');
+
+// Source tracking summary (line 323)
+_logger.log('📊 Source tracking: ${_albumSourceProviders.length} albums, ${_artistSourceProviders.length} artists, ${_audiobookSourceProviders.length} audiobooks have provider info');
+```
+

+
+## Files Changed
+
+| File | Changes |
+|------|---------|
+| `lib/services/music_assistant_api.dart` | Added provider filtering to browse API path in `getAudiobooks()`, added debug logging |
+| `lib/services/sync_service.dart` | Added audiobook counts to per-provider and summary logs |
+| `lib/providers/music_assistant_provider.dart` | Moved `notifyListeners()` to fire immediately on provider toggle |
+| `lib/screens/new_library_screen.dart` | Wrapped audiobook tabs in `Selector` to rebuild on provider changes |
+
+---
+
+## Expected Behavior After Fixes
+
+1. **Instant UI Updates:** When you toggle a provider, the library immediately updates using client-side filtering
+2. **Audiobook Source Tracking:** Audiobooks now have provider source tracking (visible in logs)
+3. **Audiobook Tab Rebuilds:** Both audiobook tabs (Authors and All Books) rebuild instantly on provider toggle
+4. **Music Tab Consistency:** Music tabs continue to work as before, now with immediate rebuilds
+
+---
+
+## Testing Checklist
+
+- [ ] Toggle a music provider, verify instant UI update (no 600ms delay)
+- [ ] Toggle between different Spotify accounts, verify correct filtering
+- [ ] Sync with ABS library filtering enabled
+- [ ] Verify audiobooks appear in source tracking log
+- [ ] Toggle ABS provider off in library menu
+- [ ] Verify audiobooks list becomes empty immediately (no pull-to-refresh needed)
+- [ ] Toggle ABS provider back on
+- [ ] Verify audiobooks reappear after sync completes
+- [ ] Test with multiple providers (Spotify audiobooks + ABS)
+

+
+## Related Documentation
+
+- `docs/SESSION_2026_01_17_PROVIDER_FILTERING.md` - Initial provider filtering implementation
+- `docs/PER_PROVIDER_SYNC_IMPLEMENTATION.md` - Per-provider sync architecture
+
+---
+
+## Known Limitations
+
+1. **Series Tab:** The Series tab still doesn't filter by provider. Series are fetched as `AudiobookSeries` objects without per-provider tracking.
+
+2. **Mixed Provider Scenario:** If user has both Spotify audiobooks and ABS audiobooks, and ABS library filtering is enabled, Spotify audiobooks may not be fetched because the browse API path is taken. This is a pre-existing architectural limitation.
+
+3. **Enabling Providers:** When ENABLING a previously disabled provider, the UI updates immediately but shows empty until the background sync completes (because the cache doesn't have that provider's data yet). This is expected behavior.

+# Session 2026-01-17: Optimistic Updates & Podcast Provider Filtering
+
+## Overview
+
+This session focused on fixing provider filtering for podcasts, resolving iTunes podcast provider issues, and implementing optimistic updates for library buttons across detail screens.
+
+## Issues Addressed
+
+### 1. Podcast Provider Counts Showing Incorrectly
+
+**Problem**: All Spotify accounts showed the same podcast count instead of only counting podcasts owned by each account.
+
+**Root Cause**: The podcast counting logic wasn't checking the `inLibrary` field on provider mappings.
+
+**Solution**:
+- Added `inLibrary` field to `ProviderMapping` model
+- Updated `getProvidersWithPodcasts()` to only count mappings where `inLibrary == true`
+- Updated podcast filtering in library screen to check `inLibrary` field
+
+**Files Modified**:
+- `lib/models/media_item.dart` - Added `inLibrary` field
+- `lib/providers/music_assistant_provider.dart` - Updated counting logic
+- `lib/screens/new_library_screen.dart` - Updated filtering logic
+
+### 2. iTunes Podcasts Not Appearing in Library
+
+**Problem**: Podcasts added from iTunes search weren't showing in library and iTunes provider filter showed 0 count.
+
+**Investigation**:
+- Added `itunes_podcasts` to provider capabilities and music provider domains
+- Added synthetic provider instance creation for search-only providers
+- Added debug logging to understand podcast loading
+
+**Resolution**: The issue was with Music Assistant's iTunes podcast provider itself - podcasts added via iTunes weren't being properly stored in the MA library. The user removed the iTunes provider from MA and re-added podcasts via Spotify search as a workaround.
+
+**Files Modified**:
+- `lib/models/provider_instance.dart` - Added `itunes_podcasts` to capabilities
+
+### 3. Episode Loading Failing for Non-Library Podcasts
+
+**Problem**: When a podcast was removed from library, the old library ID became invalid and episodes wouldn't load.
+
+**Solution**: Added fallback logic to try loading episodes via provider mappings when the primary ID fails.
+
+**Files Modified**:
+- `lib/screens/podcast_detail_screen.dart` - Added fallback episode loading
+
+### 4. Search Filtering Rework
+
+**Problem**: Server-side provider filtering was being applied to search results when it should only apply when the "in library" toggle is enabled.
+
+**Solution**:
+- Removed `filterSearchResults()` calls from search methods
+- Added client-side `_filterByEnabledProviders()` helper
+- Applied filtering only when `_libraryOnly` toggle is ON
+
+**Files Modified**:
+- `lib/providers/music_assistant_provider.dart` - Removed filterSearchResults calls
+- `lib/screens/search_screen.dart` - Added client-side filtering
+
+### 5. Library Buttons Not Updating Immediately
+
+**Problem**: Add/remove library buttons on detail screens waited for API response before updating, causing perceived lag.
+
+**Solution**: Implemented optimistic updates - update UI immediately, revert on failure.
+
+**Files Modified**:
+- `lib/screens/podcast_detail_screen.dart`
+- `lib/screens/album_details_screen.dart`
+- `lib/screens/artist_details_screen.dart`
+
+## Code Changes
+
+### ProviderMapping.inLibrary Field
+
+```dart
+// lib/models/media_item.dart
+class ProviderMapping {
+  final String itemId;
+  final String providerDomain;
+  final String providerInstance;
+  final bool available;
+  final Map<String, dynamic>? audioFormat;
+  final bool inLibrary;  // NEW: indicates ownership
+
+  factory ProviderMapping.fromJson(Map<String, dynamic> json) {
+    return ProviderMapping(
+      // ... other fields ...
+      inLibrary: json['in_library'] == true || json['in_library'] == 1,
+    );
+  }
+}
+```
+
+### Podcast Provider Counting
+
+```dart
+// lib/providers/music_assistant_provider.dart
+Map<String, int> getProvidersWithPodcasts() {
+  final counts = <String, int>{};
+  for (final item in _podcasts) {
+    final mappings = item.providerMappings;
+    if (mappings != null) {
+      for (final mapping in mappings) {
+        // Only count if this provider "owns" the item
+        if (mapping.inLibrary) {
+          final instanceId = mapping.providerInstance;
+          if (instanceId.isNotEmpty) {
+            counts[instanceId] = (counts[instanceId] ?? 0) + 1;
+          }
+        }
+      }
+    }
+  }
+  return counts;
+}
+```
+
+### Optimistic Update Pattern
+
+```dart
+// Example from podcast_detail_screen.dart
+Future<void> _toggleLibrary() async {
+  final newState = !_isInLibrary;
+
+  // OPTIMISTIC UPDATE: Update UI immediately
+  setState(() {
+    _isInLibrary = newState;
+  });
+
+  if (mounted) {
+    ScaffoldMessenger.of(context).showSnackBar(
+      SnackBar(content: Text(S.of(context)!.addedToLibrary)),
+    );
+  }
+
+  // Fire and forget - API call happens in background
+  maProvider.addToLibrary(...).catchError((e) {
+    // Revert on failure
+    if (mounted) {
+      setState(() {
+        _isInLibrary = !newState;
+      });
+    }
+  });
+}
+```
+
+### Client-Side Search Filtering
+
+```dart
+// lib/screens/search_screen.dart
+Map<String, List<MediaItem>> _filterByEnabledProviders(
+  Map<String, List<MediaItem>> results,
+  Set<String> enabledProviders,
+) {
+  if (enabledProviders.isEmpty) return results;
+
+  bool isItemAllowed(MediaItem item) {
+    final mappings = item.providerMappings;
+    if (mappings == null || mappings.isEmpty) return true;
+    return mappings.any((m) => m.inLibrary && enabledProviders.contains(m.providerInstance));
+  }
+
+  return {
+    for (final entry in results.entries)
+      entry.key: entry.value.where(isItemAllowed).toList(),
+  };
+}
+
+// Applied when setting results:
+if (_libraryOnly) {
+  final enabledProviders = provider.enabledProviderIds.toSet();
+  combinedResults = _filterByEnabledProviders(combinedResults, enabledProviders);
+}
+```
+
+## Provider Capabilities Update
+
+```dart
+// lib/models/provider_instance.dart
+static const Map<String, Set<String>> providerCapabilities = {
+  'spotify': {'artists', 'albums', 'tracks', 'playlists', 'audiobooks', 'podcasts'},
+  'ytmusic': {'artists', 'albums', 'tracks', 'playlists', 'podcasts'},
+  'apple_music': {'artists', 'albums', 'tracks', 'playlists', 'podcasts'},
+  'plex': {'artists', 'albums', 'tracks', 'playlists', 'audiobooks', 'podcasts'},
+  'jellyfin': {'artists', 'albums', 'tracks', 'playlists', 'audiobooks', 'podcasts'},
+  'emby': {'artists', 'albums', 'tracks', 'playlists', 'audiobooks', 'podcasts'},
+  'audiobookshelf': {'audiobooks', 'podcasts'},
+  'itunes_podcasts': {'podcasts'},  // NEW
+  'tunein': {'radio', 'podcasts'},
+  // ... other providers
+};
+```
+
+## Summary of All Modified Files
+
+| File | Changes |
+|------|---------|
+| `lib/models/media_item.dart` | Added `inLibrary` field to ProviderMapping |
+| `lib/models/provider_instance.dart` | Added `itunes_podcasts`, podcasts to capabilities |
+| `lib/providers/music_assistant_provider.dart` | Updated podcast counting, removed filterSearchResults |
+| `lib/screens/new_library_screen.dart` | Updated podcast filtering with inLibrary check |
+| `lib/screens/search_screen.dart` | Added client-side filtering for in-library mode |
+| `lib/screens/podcast_detail_screen.dart` | Optimistic updates, fallback episode loading |
+| `lib/screens/album_details_screen.dart` | Optimistic updates for library button |
+| `lib/screens/artist_details_screen.dart` | Optimistic updates for library button |
+
+## Key Learnings
+
+1. **inLibrary field**: Music Assistant's provider mappings include an `in_library` field that indicates whether the user added the item from that specific provider account. This is essential for accurate per-provider filtering.
+
+2. **iTunes podcast provider**: The MA iTunes podcast provider is for search only - it doesn't properly store items in the library. Users should add podcasts from streaming providers like Spotify instead.
+
+3. **Optimistic updates**: For better UX, library toggle buttons should update immediately and only revert if the API call fails, rather than waiting for API response.
+
+4. **Search vs Library filtering**: Server-side provider filtering should only apply to library views, not search results (unless the "in library" toggle is enabled).

+# Provider Filtering Improvements
+
+## Date: January 17, 2026
+
+## Overview
+
+This session focused on improving the provider filtering system across the app, building on the per-provider sync implementation. Key improvements include a cleaner capability-based architecture, fixing filter visibility bugs, and extending filtering to the audiobooks library.
+
+---
+
+## Changes Made
+
+### 1. Provider Capability Mapping
+
+**File:** `lib/models/provider_instance.dart`
+
+Replaced the clunky item-count-based filtering with a static capability map that defines what content types each provider domain supports.
+
+```dart
+static const Map<String, Set<String>> providerCapabilities = {
+  // Music streaming services
+  'spotify': {'artists', 'albums', 'tracks', 'playlists', 'audiobooks'},
+  'tidal': {'artists', 'albums', 'tracks', 'playlists'},
+  'qobuz': {'artists', 'albums', 'tracks', 'playlists'},
+  'deezer': {'artists', 'albums', 'tracks', 'playlists'},
+  'ytmusic': {'artists', 'albums', 'tracks', 'playlists'},
+  'soundcloud': {'artists', 'albums', 'tracks', 'playlists'},
+  'apple_music': {'artists', 'albums', 'tracks', 'playlists'},
+  'amazon_music': {'artists', 'albums', 'tracks', 'playlists'},
+
+  // Self-hosted media servers (can have music and audiobooks)
+  'plex': {'artists', 'albums', 'tracks', 'playlists', 'audiobooks'},
+  'jellyfin': {'artists', 'albums', 'tracks', 'playlists', 'audiobooks'},
+  'emby': {'artists', 'albums', 'tracks', 'playlists', 'audiobooks'},
+
+  // Music-only servers
+  'subsonic': {'artists', 'albums', 'tracks', 'playlists'},
+  'opensubsonic': {'artists', 'albums', 'tracks', 'playlists'},
+  'navidrome': {'artists', 'albums', 'tracks', 'playlists'},
+  'filesystem': {'artists', 'albums', 'tracks', 'playlists'},
+
+  // Audiobook-only providers
+  'audiobookshelf': {'audiobooks'},
+
+  // Radio providers
+  'tunein': {'radio'},
+  'radiobrowser': {'radio'},
+
+  // Player/system providers (no library content)
+  'snapcast': <String>{},
+  'fully_kiosk': <String>{},
+};
+```
+
+**Added helper methods:**
+```dart
+Set<String> get supportedContentTypes => providerCapabilities[domain] ?? <String>{};
+bool supportsContentType(String category) => supportedContentTypes.contains(category);
+```
+
+**Benefits:**
+- Radio providers never show in Artists tab (by design, not by count)
+- Works immediately, even with empty libraries
+- Disabled providers still show in menu (if they support the content type)
+- Clean separation of concerns
+
+---
+
+### 2. Updated Provider Filtering in MusicAssistantProvider
+
+**File:** `lib/providers/music_assistant_provider.dart`
+
+Updated `getRelevantProvidersForCategory()` to filter by capability:
+
+```dart
+List<(ProviderInstance, int)> getRelevantProvidersForCategory(String category) {
+  // ... get counts ...
+
+  final result = <(ProviderInstance, int)>[];
+  for (final provider in _availableMusicProviders) {
+    // Only include providers that support this content type
+    if (provider.supportsContentType(category)) {
+      final count = counts[provider.instanceId] ?? 0;
+      result.add((provider, count));
+    }
+  }
+  // ...
+}
+```
+
+---
+
+### 3. Simplified Library Menu Provider Filter
+
+**File:** `lib/screens/new_library_screen.dart`
+
+Simplified the options menu overlay to show all providers that support the current category:
+
+**Before (clunky):**
+```dart
+if (widget.relevantProviders.where((p) {
+  final hasItems = p.$2 > 0;
+  final isDisabledByUser = widget.enabledProviderIds.isNotEmpty &&
+      !widget.enabledProviderIds.contains(p.$1.instanceId);
+  return hasItems || isDisabledByUser;
+}).length > 1) ...[
+```
+
+**After (clean):**
+```dart
+// relevantProviders is pre-filtered by capability
+if (widget.relevantProviders.length > 1) ...[
+  // Show all providers that support this category
+  ...widget.relevantProviders.map((providerData) {
+```
+
+---
+
+### 4. Removed Provider Toggles from Settings Screen
+
+**File:** `lib/screens/settings_screen.dart`
+
+Removed the "Music Providers" section entirely since provider filtering is now handled in the library menu:
+
+- Removed `_providerEnabled` state variable
+- Removed provider loading code from `_loadSettings()`
+- Removed the entire Music Providers UI section (~100 lines)
+
+**Rationale:** Single source of truth - provider toggles now only appear in the library menu where they're contextually relevant.
+
+---
+
+### 5. Fixed Audiobooks Library Provider Filtering
+
+**File:** `lib/screens/new_library_screen.dart`
+
+The audiobooks tabs were not filtering by provider - they loaded data once and displayed it without responding to provider changes.
+
+**Fixed `_buildBooksAuthorsTab()`:**
+```dart
+final syncService = SyncService.instance;
+final enabledProviders = maProvider.enabledProviderIds.toSet();
+
+// Client-side filtering using SyncService source tracking
+var audiobooks = syncService.hasSourceTracking && enabledProviders.isNotEmpty
+    ? syncService.getAudiobooksFilteredByProviders(enabledProviders)
+    : List<Audiobook>.from(_audiobooks);
+
+// Filter by favorites if enabled
+if (_showFavoritesOnly) {
+  audiobooks = audiobooks.where((a) => a.favorite == true).toList();
+}
+
+// Group filtered audiobooks by author (dynamic, not cached)
+final groupedByAuthor = <String, List<Audiobook>>{};
+for (final book in audiobooks) {
+  final authorName = book.authorsString;
+  groupedByAuthor.putIfAbsent(authorName, () => []).add(book);
+}
+```
+
+**Fixed `_buildAllBooksTab()`:**
+- Same provider filtering pattern
+- Dynamic sorting after filtering
+- Updated PageStorageKey to include provider count for proper rebuild
+
+---
+
+## Bug Fixes
+
+### Provider Filter Menu Disappearing
+
+**Problem:** When providers were deselected, the background sync would clear the cache and only fetch data for enabled providers. Disabled providers then had 0 items, and the menu required `> 1 providers WITH items` to show. The entire Providers section would disappear.
+
+**Solution:** Changed to capability-based filtering. The menu now shows all providers that support the category, regardless of item count.
+
+### Audiobooks Not Filtering by Provider
+
+**Problem:** Audiobooks tabs loaded data once into `_audiobooks` and displayed it without provider filtering. Toggling providers in the menu had no effect.
+
+**Solution:** Added inline provider filtering during build (same pattern as music tabs).
+
+---
+
+## Files Changed

+|------|---------|
+| `lib/models/provider_instance.dart` | Added `providerCapabilities` map and helper methods |
+| `lib/providers/music_assistant_provider.dart` | Updated `getRelevantProvidersForCategory()` to filter by capability |
+| `lib/screens/new_library_screen.dart` | Simplified menu filter logic, added audiobook provider filtering |
+| `lib/screens/settings_screen.dart` | Removed Music Providers section |

+
+## Known Limitations
+
+1. **Series Tab:** The Series tab in audiobooks doesn't filter by provider yet. Series are fetched separately as `AudiobookSeries` objects and don't have the same source tracking as individual audiobooks.
+
+2. **First Sync Required:** Source tracking only works after at least one sync with providers enabled.
+
+---
+
+## Testing Checklist
+

+# Discovery Rows Submenu - Implementation Plan
+
+## Option: Hybrid with Discovery Badge
+
+### Overview
+Transform the "Discovery Mixes" toggle into a section that:
+1. Shows individual discovery row toggles
+2. Adds those rows to the main home row list with visual distinction
+3. Allows full reordering alongside other rows
+
+---
+
+## UI Design
+
+### Settings Screen - Discovery Section
+
+```
+┌─────────────────────────────────────────────┐
+│ ⚬ Discovery Mixes                        ● │
+│   Show discovery-based rows on home screen │
+│   ──────────────────────────────────────── │
+│   Discovery rows from Music Assistant:     │

+
+### Main Home Row List - With Badge
+
+Discovery rows appear interleaved with a badge:
+
+```
+┌─────────────────────────────────────────────┐

+│ ⋮ ☑ Favorite Albums                      ● │
+└─────────────────────────────────────────────┘
+```
+
+Badge style: Small chip/icon indicating this is a dynamic discovery row.
+
+---
+
+## Technical Changes
+
+### 1. Settings Screen (`lib/screens/settings_screen.dart`)
+
+**Add state for discovery folders:**
+```dart
+List<RecommendationFolder> _discoveryFolders = [];
+Map<String, bool> _discoveryRowEnabled = {}; // itemId -> enabled
+bool _isDiscoveryFoldersExpanded = false;
+```
+
+**New methods:**
+```dart
+Future<void> _loadDiscoveryFolders() async { }
+Future<void> _refreshDiscoveryFolders() async { }
+void _toggleDiscoveryRow(String itemId, bool enabled) { }
+void _toggleDiscoveryMixes(bool enabled) { }
+Widget _buildDiscoverySection() { }
+```
+
+**Modify existing:**
+- `_loadSettings()` - load discovery row preferences
+- Home row list builder - filter out individual discovery rows
+- Add discovery section before home row list
+
+### 2. Settings Service (`lib/services/settings_service.dart`)
+
+**New methods:**
+```dart
+static Future<bool> getShowDiscoveryFolders() async { }
+static Future<void> setShowDiscoveryFolders(bool value) async { }
+
+// Per-row discovery preferences
+static Future<Map<String, bool>> getDiscoveryRowPreferences() async { }
+static Future<void> setDiscoveryRowPreference(String itemId, bool enabled) async { }
+static Future<void> setDiscoveryRowPreferences(Map<String, bool> prefs) async { }
+```
+
+**Storage key pattern:**
+- `discovery_folders_enabled` (bool)
+- `discovery_row_{itemId}` (bool per row)
+
+### 3. Provider (`lib/providers/music_assistant_provider.dart`)
+
+**Already has:** `getDiscoveryFoldersWithCache()`
+
+**Add method:**
+```dart
+Future<void> refreshDiscoveryFolders() async {
+  // Clear cache and refetch from API
+  _cacheService.clearDiscoveryFoldersCache();
+  await getDiscoveryFoldersWithCache();
+}
+```
+
+### 4. Home Screen (`lib/screens/new_home_screen.dart`)
+
+**Changes to row rendering:**
+
+Instead of a single `_discoveryFolders` list, discovery rows are integrated into `_homeRowOrder`:
+
+```dart
+// Before: static list of row IDs
+List<String> _homeRowOrder = ['recent-albums', 'discover-artists', ...];
+
+// After: can include discovery row IDs
+List<String> _homeRowOrder = [
+  'recent-albums',
+  'discovery:abc123',  // Discovery row ID
+  'discover-artists',
+  'discovery:def456',
+  ...
+];
+```
+
+**New method:**
+```dart
+bool _isDiscoveryRowId(String rowId) {
+  return rowId.startsWith('discovery:');
+}
+
+String _getDiscoveryRowItemId(String rowId) {
+  return rowId.substring('discovery:'.length);
+}
+```
+
+**Modify row rendering:**
+- Check if rowId is a discovery row
+- If yes, render DiscoveryRow widget with that folder
+- Cache discovery folders for quick lookup
+
+### 5. Localization (`lib/l10n/app_en.arb`)
+
+**Add strings:**
+```json
+{
+  "discoveryMixesDescription": "Show personalized recommendations from Music Assistant",
+  "discoveryRows": "Discovery rows from Music Assistant",
+  "refreshDiscoveryRows": "Refresh available rows",
+  "noDiscoveryRows": "No discovery rows available",
+  "discoveryRowBadge": "Music Assistant"
+}
+```
+
+### 6. Models (`lib/models/recommendation_folder.dart`)
+
+**Add property:**
+```dart
+class RecommendationFolder {
+  ...
+  /// Unique ID for use in row ordering and settings
+  String get rowId => 'discovery:$itemId';
+}
+```
+
+---
+
+## Data Flow

+│  5. Handle reordering including discovery rows                  │
+└─────────────────────────────────────────────────────────────────┘
+```
+
+---
+
+## Migration Path
+
+### Phase 1: Settings Screen (No breaking changes)
+- Add discovery section to settings
+- Load and display discovery folders
+- Individual row toggles (but don't affect home screen yet)
+- Refresh button
+
+### Phase 2: Home Screen Integration
+- Modify home row order to support discovery row IDs
+- Render discovery rows in main list
+- Add badge visual distinction
+
+### Phase 3: Polish
+- Translations
+- Edge cases (folder disappears from MA)
+- Performance (lazy loading)
+
+---
+
+## Edge Cases & Considerations
+
+| Issue | Solution |
+|-------|----------|
+| Discovery folder no longer returned by MA | Keep user preference, hide row if not found |
+| User reorders then MA returns new folders | New folders appended to end of discovery section |
+| All discovery rows disabled | Discovery section shows but appears empty/minimized |
+| Many discovery folders (10+) | Show scrollable sublist, keep main setting compact |
+| Row ID collision | Use `discovery:{itemId}` prefix ensures uniqueness |
+
+---
+

-# Ensemble Navigation Restructure Implementation Summary
-
-**Implementation Date:** December 4, 2025
-**Branch:** feature/fixed-bottom-nav-fluid-animations
-**Implemented By:** Claude Code
-**Status:** Complete - Ready for Testing
-
----
-
-## Overview
-
-This document summarizes the implementation of the Ensemble app navigation restructuring to achieve fixed bottom navigation, fluid hero animations, and seamless mini player expansion.
-
-### Goals Achieved
-
-1. **Fixed Bottom Navigation Bar** - Bottom nav no longer animates during page transitions
-2. **Fluid Hero Animations** - All hero animations morph smoothly, including the previously broken Library → Artist animation
-3. **Mini Player Over Bottom Nav** - Mini player correctly expands over the fixed bottom navigation
-4. **Adaptive Color Flow** - Adaptive colors update smoothly on the fixed bottom navigation
-
----
-
-## What Was Changed
-
-### Phase 1: Fix Library → Artist Hero Animation
-
-**File Modified:** `/home/home-server/Ensemble/lib/screens/new_library_screen.dart`
-
-**Changes:**
-- Added import for `../constants/hero_tags.dart`
-- Wrapped `CircleAvatar` in `Hero` widget with tag: `HeroTags.artistImage + uri + '_library'`
-- Wrapped artist name `Text` in `Hero` widget with tag: `HeroTags.artistName + uri + '_library'`
-- Added `Material` wrapper to text hero with transparent color (required for text heroes)
-
-**Impact:** Library → Artist navigation now has smooth hero animation instead of cross-fade
-
-**Commit:** `c38e266` - "feat: add Hero widgets to Library artist tiles"
-
----
-
-### Phase 2: Remove AlbumDetailsScreen Bottom Nav
-

-
-**Changes:**
-- Removed entire `bottomNavigationBar` property from Scaffold (lines 341-388)
-- Deleted 48 lines of duplicate navigation bar code
-
-**Impact:**
-- No bottom navigation animation when navigating to album details
-- Bottom nav remains fixed at HomeScreen level
-- Cleaner, simpler detail screen
-
-**Commit:** `f16522b` - "feat: remove duplicate bottom navigation from AlbumDetailsScreen"
-
----
-
-### Phase 3: Remove ArtistDetailsScreen Bottom Nav
-
-**File Modified:** `/home/home-server/Ensemble/lib/screens/artist_details_screen.dart`
-
-**Changes:**
-- Removed entire `bottomNavigationBar` property from Scaffold (lines 162-209)
-- Deleted 48 lines of duplicate navigation bar code
-
-**Impact:**
-- Consistent with album details behavior
-- No bottom navigation animation when navigating to artist details
-- Bottom nav remains fixed at HomeScreen level
-
-**Commit:** `152eff5` - "feat: remove duplicate bottom navigation from ArtistDetailsScreen"
-
----
-
-### Phase 4: Integration Testing & Validation
-
-**Activities:**
-- Code-level validation of all changes
-- Verified bottomNavigationBar removed from both detail screens
-- Verified Hero tags correctly added to Library screen
-- Verified HomeScreen bottom nav still exists
-- Verified hero tag consistency between screens
-- Verified GlobalPlayerOverlay Stack structure unchanged
-- Verified adaptive color implementation intact
-
-**Results:** All validation checks passed
-
----
-
-### Phase 5: Polish & Optional Enhancements
-
-**Files Modified:**
-- `/home/home-server/Ensemble/lib/screens/album_details_screen.dart`
-- `/home/home-server/Ensemble/lib/screens/artist_details_screen.dart`
-
-**Changes:**
-- Reduced bottom padding from 140px to 80px in both detail screens
-- Updated comments to reflect change (removed "bottom nav" reference)
-
-**Impact:**
-- More content visible before scrolling
-- Appropriate spacing for mini player only (no bottom nav needed)
-
-**Commit:** `22ce7a3` - "polish: reduce bottom padding in detail screens"
-
----
-
-## Key Architectural Decisions
-
-### 1. Remove Bottom Nav vs. Fix It
-
-**Decision:** Remove duplicate bottom navigation bars from detail screens entirely
-
-**Rationale:**
-- Simplest solution (only removes code, no complex refactoring)
-- Completely eliminates bottom nav animation during transitions
-- Standard pattern used by major music apps (Spotify, Apple Music)
-- Reduces widget tree complexity
-- Focuses user attention on detail content
-
-**Alternative Considered:** Keep bottom nav everywhere with adaptive colors - Would still show cross-fade animation during transitions
-
----
-
-### 2. Hero Animation Approach
-
-**Decision:** Add Hero widgets to match existing pattern, keep FadeSlidePageRoute
-
-**Rationale:**
-- Library artist tiles were missing Hero widgets that ArtistDetailsScreen expected
-- Solution follows existing successful pattern from ArtistCard widget
-- Simple fix with low risk
-- FadeSlidePageRoute doesn't interfere with hero animations once tags match
-
-**Alternative Considered:** Switch to MaterialPageRoute - Not necessary since FadeSlidePageRoute works fine with proper hero tags
-
----
-
-### 3. Bottom Padding Reduction
-
-**Decision:** Reduce from 140px to 80px
-
-**Rationale:**
-- Original 140px was for mini player (64px) + bottom nav (56px) + margins
-- With bottom nav removed from detail screens, only need space for mini player
-- 80px provides adequate space (64px player + 16px buffer)
-- More content visible without sacrificing usability
-
----
-
-## Code Quality Highlights
-
-### Clean Implementation
-- No hardcoded values introduced
-- Consistent animation patterns maintained
-- Proper hero tag construction following existing conventions
-- Material wrapper on text heroes (required by Flutter)
-
-### Architecture Preservation
-- No changes to ThemeProvider
-- No changes to GlobalPlayerOverlay
-- No changes to ExpandablePlayer
-- No changes to navigation system (still using Navigator.push)
-- All core systems left intact
-
-### Code Reduction
-- Net deletion of ~96 lines of duplicate code
-- Added ~15 lines for hero widgets
-- **Total: -81 lines** (simpler, cleaner codebase)
-
----
-
-## Known Limitations
-
-### Navigation Pattern
-- Users can no longer switch tabs directly from album/artist detail screens
-- Must use back button/gesture to return to main navigation
-- This is intentional and follows industry standard patterns
-
-### Hero Animation Timing
-- Hero animations use Flutter's default timing (300ms)
-- Consistent with MaterialPageRoute and FadeSlidePageRoute
-- If custom timing is desired, would need custom hero flight shuttle builder
-
----
-
-## Future Improvements
-
-### Optional Enhancements Not Implemented
-These were considered but deemed unnecessary after code review:
-
-1. **Back Button Visibility Enhancement** - Current AppBar back button is sufficient
-2. **Smooth Color Transition Animation** - Current implementation already smooth via ThemeProvider
-3. **Custom Page Transitions** - FadeSlidePageRoute works well with hero animations
-4. **Empty State Navigation Hints** - Users understand standard back navigation
-
-### Potential Future Work
-- **Performance Profiling:** Test on low-end devices to ensure 60 FPS
-- **User Testing:** Gather feedback on navigation UX without bottom nav in details
-- **go_router Migration:** If app grows complex, consider router-based navigation
-- **Gesture Navigation:** Could add swipe-between-tabs from detail screens if needed
-

+# Feature: Replace "Play On" Popups with Player Selector
+
+## Overview
+
+Replace the `PlayerPickerSheet` popup modal with the existing Player Selector (reveal overlay) when users tap "Play on" buttons throughout the app. This provides a consistent, richer player selection experience.
+
+## Current State
+
+### PlayerPickerSheet Popup
+Used in 7+ places:
+- `album_details_screen.dart` - Play Album, Play From Here, Play Radio
+- `playlist_details_screen.dart` - Play Playlist, Play Radio
+- `search_screen.dart` - Play album/playlist/audiobook/radio from search
+- `podcast_detail_screen.dart` - Play Episode
+- `audiobook_detail_screen.dart` - Play Audiobook
+- `queue_screen.dart` - Transfer Queue (special case - keep popup)
+
+### Player Selector (Reveal Overlay)
+- Location: `lib/widgets/player/player_reveal_overlay.dart`
+- Shows vertical list of all players with artwork, current track, sync status
+- Has hints above player list: "Long-press to sync" & "Swipe to adjust volume"
+- Triggered by pull-down gesture or device button tap
+
+## Proposed Changes
+
+### 1. Modify PlayerRevealOverlay
+
+**File:** `lib/widgets/player/player_reveal_overlay.dart`
+
+Add new optional parameters:
+
+```dart
+class PlayerRevealOverlay extends StatefulWidget {
+  final VoidCallback onDismiss;
+  final double miniPlayerBottom;
+  final double miniPlayerHeight;
+  final bool showOnboardingHints;
+
+  // NEW: Callback when player is selected for a pending action
+  final void Function(Player player)? onPlayerSelected;
+
+  // NEW: Context hint to display instead of default hints
+  // e.g., "Select player to play album"
+  final String? contextHint;
+
+  // NEW: Icon for context hint (default: speaker icon)
+  final IconData? contextHintIcon;
+```
+
+### 2. Modify Hint Display
+
+**File:** `lib/widgets/player/player_reveal_overlay.dart` (around line 386-394)
+
+```dart
+// Current:
+: Column(
+    mainAxisSize: MainAxisSize.min,
+    children: [
+      buildHintRow(Icons.lightbulb_outline, S.of(context)!.holdToSync),
+      const SizedBox(height: 4),
+      buildHintRow(Icons.lightbulb_outline, S.of(context)!.swipeToAdjustVolume),
+    ],
+  ),
+
+// New:
+: widget.contextHint != null
+    ? buildHintRow(
+        widget.contextHintIcon ?? Icons.play_circle_outline,
+        widget.contextHint!,
+      )
+    : Column(
+        mainAxisSize: MainAxisSize.min,
+        children: [
+          buildHintRow(Icons.lightbulb_outline, S.of(context)!.holdToSync),
+          const SizedBox(height: 4),
+          buildHintRow(Icons.lightbulb_outline, S.of(context)!.swipeToAdjustVolume),
+        ],
+      ),
+```
+
+### 3. Modify Player Card onTap
+
+**File:** `lib/widgets/player/player_reveal_overlay.dart` (around line 437-441 and 490-494)
+
+```dart
+// Current:
+onTap: () {
+  HapticFeedback.mediumImpact();
+  maProvider.selectPlayer(data.player);
+  dismiss();
+},
+
+// New:
+onTap: () {
+  HapticFeedback.mediumImpact();
+  if (widget.onPlayerSelected != null) {
+    // Execute the pending action with selected player
+    widget.onPlayerSelected!(data.player);
+  } else {
+    // Default behavior: just select the player
+    maProvider.selectPlayer(data.player);
+  }
+  dismiss();
+},
+```
+
+### 4. Add Helper Method to GlobalPlayerOverlay
+
+**File:** `lib/widgets/global_player_overlay.dart`
+
+Add a static method to show player selector with pending action:
+
+```dart
+/// Show player selector for a "Play on" action
+///
+/// [contextHint] - Message shown instead of default hints
+/// [onPlayerSelected] - Called when user taps a player
+///
+/// Example:
+/// ```dart
+/// GlobalPlayerOverlay.showPlayerSelectorForAction(
+///   contextHint: "Select player to play album",
+///   onPlayerSelected: (player) {
+///     provider.playAlbum(albumId, playerId: player.playerId);
+///   },
+/// );
+/// ```
+static void showPlayerSelectorForAction({
+  required String contextHint,
+  required void Function(Player player) onPlayerSelected,
+  IconData? hintIcon,
+}) {
+  // Implementation: trigger the player reveal overlay with these parameters
+  // May need to store pending action in state and pass to overlay
+}
+```
+
+### 5. Update Calling Sites
+
+Replace `showPlayerPickerSheet()` calls with new method:
+
+**Example - album_details_screen.dart:**
+
+```dart
+// Current (around line 1305-1316):
+showPlayerPickerSheet(
+  context: context,
+  title: 'Play Album',
+  onPlayerSelected: (player) async {
+    GlobalPlayerOverlay.hidePlayer();
+    await maProvider.playAlbum(albumId, playerId: player.playerId);
+    GlobalPlayerOverlay.showPlayer();
+  },
+);
+
+// New:
+GlobalPlayerOverlay.showPlayerSelectorForAction(
+  contextHint: S.of(context)!.selectPlayerToPlayAlbum, // Add localization
+  onPlayerSelected: (player) async {
+    await maProvider.playAlbum(albumId, playerId: player.playerId);
+  },
+);
+```
+
+### 6. Add Localizations
+
+**File:** `lib/l10n/app_en.arb` (and other language files)
+
+```json
+"selectPlayerToPlay": "Select player to play",
+"selectPlayerToPlayAlbum": "Select player to play album",
+"selectPlayerToPlayPlaylist": "Select player to play playlist",
+"selectPlayerToPlayRadio": "Select player to start radio",
+"selectPlayerToPlayEpisode": "Select player to play episode",
+"selectPlayerToPlayAudiobook": "Select player to play audiobook"
+```
+
+## Files to Modify
+
+1. `lib/widgets/player/player_reveal_overlay.dart` - Add parameters, modify hints & onTap
+2. `lib/widgets/global_player_overlay.dart` - Add helper method
+3. `lib/screens/album_details_screen.dart` - Replace 3 popup calls
+4. `lib/screens/playlist_details_screen.dart` - Replace 2 popup calls
+5. `lib/screens/search_screen.dart` - Replace ~5 popup calls
+6. `lib/screens/podcast_detail_screen.dart` - Replace 1 popup call
+7. `lib/screens/audiobook_detail_screen.dart` - Replace 1 popup call
+8. `lib/l10n/app_en.arb` - Add new strings
+9. `lib/l10n/app_de.arb`, `app_fr.arb`, `app_es.arb` - Translations
+
+## Exception: Queue Transfer
+
+**Keep the popup for `queue_screen.dart`** because:
+- Needs to filter out current player (can't transfer to self)
+- Needs to filter out certain player types
+- Different UX intent (transfer vs play)
+
+## Implementation Order
+
+1. Modify `PlayerRevealOverlay` to accept new parameters
+2. Add helper method to `GlobalPlayerOverlay`
+3. Test with one screen (album_details_screen.dart)
+4. Add localizations
+5. Migrate remaining screens
+6. Clean up unused code from PlayerPickerSheet if no longer needed elsewhere
+
+## Testing Checklist
+
+- [ ] Album details: Play Album button
+- [ ] Album details: Play From Here (track context menu)
+- [ ] Album details: Play Radio (track context menu)
+- [ ] Playlist details: Play Playlist button
+- [ ] Playlist details: Play Radio (track context menu)
+- [ ] Search: Play album from results
+- [ ] Search: Play playlist from results
+- [ ] Search: Play radio from results
+- [ ] Podcast detail: Play episode
+- [ ] Audiobook detail: Play audiobook
+- [ ] Queue transfer still works with popup
+- [ ] Long-press to sync still works in player selector
+- [ ] Dismiss by tapping backdrop works
+- [ ] Dismiss by swiping down works

+# Remote Connection - Future Implementation Guide
+
+## Overview
+
+This document provides guidance for implementing remote connection to Music Assistant servers via WebRTC. Remote connection allows the Ensemble app to connect to MA servers outside the local network using Nabu Casa's WebRTC signaling infrastructure.
+
+## Current Status: On Hold
+
+Remote connection was partially implemented but put on hold due to a critical bug where the `ma-api` data channel becomes one-way after 1-3 minutes. See `MA_WEBRTC_BUG_REPORT.md` for details.
+
+---
+
+## Architecture
+
+### How It Works
+
+```

+```
+
+### Components
+
+1. **SignalingClient** - WebSocket connection to `wss://signaling.music-assistant.io/ws`
+2. **WebRTCConnection** - Manages RTCPeerConnection and data channels
+3. **RemoteBridge** - Bridges local WebSocket API to remote WebRTC connection
+
+### Data Channels
+
+| Channel | Purpose | Traffic Pattern |
+|---------|---------|-----------------|
+| `ma-api` | JSON API requests/responses | High volume, large payloads |
+| `sendspin` | Audio streaming + control | Low JSON, binary audio data |
+
+---
+
+## Key Files to Create/Modify
+
+### New Files
+
+| File | Purpose |
+|------|---------|
+| `lib/services/remote/signaling_client.dart` | WebSocket client for signaling server |
+| `lib/services/remote/webrtc_connection.dart` | WebRTC peer connection management |
+| `lib/services/remote/remote_bridge.dart` | Bridges API calls to WebRTC |
+
+### Files to Modify
+
+| File | Changes |
+|------|---------|
+| `lib/services/music_assistant_api.dart` | Add remote connection fallback |
+| `lib/providers/music_assistant_provider.dart` | Expose remote connection state |
+| `pubspec.yaml` | Add `flutter_webrtc` dependency |
+
+---
+
+## Implementation Steps
+
+### Step 1: Add Dependencies
+
+```yaml
+# pubspec.yaml
+dependencies:
+  flutter_webrtc: ^0.12.0  # or latest
+```
+
+### Step 2: Implement SignalingClient
+
+The signaling client connects to Music Assistant's signaling server and exchanges WebRTC offers/answers.
+
+```dart
+class SignalingClient {
+  WebSocket? _socket;
+
+  Future<void> connect(String serverId) async {
+    _socket = await WebSocket.connect('wss://signaling.music-assistant.io/ws');
+
+    // Send connect request
+    _send({
+      'type': 'connect-request',
+      'server_id': serverId,
+    });
+
+    // Listen for messages
+    _socket!.listen(_handleMessage);
+  }
+
+  void _handleMessage(dynamic data) {
+    final message = jsonDecode(data);
+    switch (message['type']) {
+      case 'answer':
+        onAnswer?.call(message['sdp']);
+        break;
+      case 'ice-candidate':
+        onIceCandidate?.call(message['candidate']);
+        break;
+    }
+  }
+}
+```
+
+### Step 3: Implement WebRTCConnection
+
+```dart
+class WebRTCConnection {
+  RTCPeerConnection? _peerConnection;
+  RTCDataChannel? _apiChannel;
+  RTCDataChannel? _sendspinChannel;
+
+  Future<void> connect(SignalingClient signaling) async {
+    // Create peer connection with STUN/TURN servers
+    _peerConnection = await createPeerConnection({
+      'iceServers': [
+        {'urls': 'stun:stun.l.google.com:19302'},
+        // TURN servers provided by signaling
+      ],
+    });
+
+    // Create data channels BEFORE creating offer
+    _apiChannel = await _peerConnection!.createDataChannel(
+      'ma-api',
+      RTCDataChannelInit()..ordered = true,
+    );
+
+    _sendspinChannel = await _peerConnection!.createDataChannel(
+      'sendspin',
+      RTCDataChannelInit()..ordered = true,
+    );
+
+    // Create and send offer
+    final offer = await _peerConnection!.createOffer();
+    await _peerConnection!.setLocalDescription(offer);
+    signaling.sendOffer(offer.sdp!);
+
+    // Handle answer from server
+    signaling.onAnswer = (sdp) async {
+      await _peerConnection!.setRemoteDescription(
+        RTCSessionDescription(sdp, 'answer'),
+      );
+    };
+  }
+}
+```
+
+### Step 4: Implement RemoteBridge
+
+The bridge translates between the local WebSocket API format and WebRTC data channel messages.
+
+```dart
+class RemoteBridge {
+  final WebRTCConnection _webrtc;
+  final StreamController<String> _messageController;
+
+  void sendCommand(String json) {
+    _webrtc.sendToApiChannel(json);
+  }
+
+  Stream<String> get messages => _messageController.stream;
+}
+```
+
+### Step 5: Integrate with MusicAssistantAPI
+
+```dart
+class MusicAssistantAPI {
+  WebSocket? _localSocket;
+  RemoteBridge? _remoteBridge;
+
+  Future<void> connect(String host, {String? serverId}) async {
+    try {
+      // Try local connection first
+      _localSocket = await WebSocket.connect('ws://$host/ws');
+    } catch (e) {
+      // Fall back to remote if serverId provided
+      if (serverId != null) {
+        _remoteBridge = RemoteBridge();
+        await _remoteBridge!.connect(serverId);
+      }
+    }
+  }
+}
+```
+
+---
+
+## Critical Implementation Details
+
+### 1. Channel Creation Order
+
+The client MUST create data channels BEFORE sending the WebRTC offer. The server expects the client to create:
+- `ma-api` - for API traffic
+- `sendspin` - for audio streaming (optional)
+
+### 2. Health Monitoring
+
+Implement aggressive health checks because data channels can silently die:
+
+```dart
+// Track message counts
+int _sentCount = 0;
+int _recvCount = 0;
+DateTime _lastRecvTime = DateTime.now();
+
+// Health check every 10 seconds
+void _healthCheck() {
+  final timeSinceRecv = DateTime.now().difference(_lastRecvTime);
+  if (timeSinceRecv.inSeconds > 30) {
+    // Channel is dead, trigger reconnection
+    _reconnect();
+  }
+}
+```
+
+### 3. Keepalive Messages
+
+Send periodic keepalive on the data channel itself (not just signaling):
+
+```dart
+void _sendKeepalive() {
+  _apiChannel?.send(RTCDataChannelMessage(
+    jsonEncode({'type': 'ping', 'timestamp': DateTime.now().toIso8601String()}),
+  ));
+}
+```
+
+### 4. Flow Control
+
+Monitor buffer to prevent overflow:
+
+```dart
+void sendMessage(String json) {
+  if (_apiChannel!.bufferedAmount > 1048576) {  // 1MB
+    // Queue message, don't send
+    _sendQueue.add(json);
+    return;
+  }
+  _apiChannel!.send(RTCDataChannelMessage(json));
+}
+```
+
+---
+
+## Known Issues & Pitfalls
+
+### 1. One-Way Channel Death (CRITICAL - UNSOLVED)
+
+The `ma-api` channel stops receiving after 1-3 minutes while `sendspin` continues working. This occurs in both flutter_webrtc and WebView implementations.
+
+**Workaround options:**
+- Detect via health check and force reconnection
+- Try single-channel multiplexing (see `PLAN_B_SINGLE_CHANNEL.md`)
+- Report to MA team and wait for server-side fix
+
+### 2. flutter_webrtc Quirks
+
+- `RTCDataChannel.state` may show "open" when actually dead
+- `bufferedAmount` accuracy varies by platform
+- `onBufferedAmountLow` callback support inconsistent
+
+### 3. Android Background Throttling
+
+Android aggressively throttles background WebRTC. Consider:
+- Foreground service for sustained connections
+- Reconnection on app resume
+
+### 4. ICE/TURN Issues
+
+- aiortc (server-side) has known TURN + DataChannel bugs
+- May need ICE restart on network changes
+
+---
+
+## Testing Checklist
+
+- [ ] Connect via remote when local unavailable
+- [ ] Verify API commands work (players/all, library queries)
+- [ ] Test sustained connection (30+ minutes)
+- [ ] Test app backgrounding and resume
+- [ ] Test network transitions (WiFi ↔ cellular)
+- [ ] Verify reconnection after channel death
+- [ ] Test sendspin audio streaming (if implemented)
+
+---

+# WebRTC Data Channel Failure on Android - Bug Report
+
+## Summary
+
+When connecting to Music Assistant via WebRTC remote access (Nabu Casa), the `ma-api` data channel becomes **one-way** (can send, cannot receive) after 1-3 minutes of use, while the `sendspin` channel continues working normally.
+
+## Environment
+
+- **MA Server**: 2.8.0b7 (Home Assistant add-on)
+- **Client**: Android app (Flutter) connecting via Nabu Casa remote access
+- **Remote Access**: WebRTC via `wss://signaling.music-assistant.io/ws`
+
+## Reproduction Steps
+
+1. Connect to MA server via WebRTC remote access (not local network)
+2. Use the app normally - browse library, view players
+3. After 1-3 minutes, the connection degrades
+4. Commands time out, but signaling ping/pong continues working
+
+## Observed Behavior
+
+### Timeline from logs:
+
+```
+07:14:20 - Working normally
+           Health: API sent:51 recv:54 (balanced)
+
+07:15:57 - Receive stops
+           Health: API sent:97 recv:97, lastRecv:12s ago
+
+07:16:02 - Timeouts begin
+           "TimeoutException: Command timeout: players/all"
+

+
+### Key Observation
+
+| Channel | Traffic Pattern | Status |
+|---------|-----------------|--------|
+| `ma-api` | High (10+ msg/s, large payloads) | **FAILS** - stops receiving |
+| `sendspin` | Low (~1 msg/5s, small payloads) | **SURVIVES** - continues working |
+| Signaling | Ping/pong every 15s | **SURVIVES** - continues working |
+
+The WebRTC peer connection remains in "connected" state. ICE connection shows "completed". Only the ma-api data channel stops receiving.
+
+## Testing Performed
+
+### Test 1: flutter_webrtc (Native WebRTC)
+- **Result**: ma-api channel dies after 1-3 minutes
+- **Sendspin**: Continues working
+
+### Test 2: WebView-based WebRTC (Browser engine)
+- **Hypothesis**: Use Android WebView's browser-native WebRTC, since MA Web UI works
+- **Implementation**: Hidden InAppWebView running JavaScript WebRTC engine
+- **Result**: **Same failure mode** - ma-api dies, sendspin survives
+- **Conclusion**: Not a flutter_webrtc bug
+
+### Test 3: Various Data Channel Settings
+- Tried `ordered: false` with `maxRetransmits: 3`
+- Tried letting server create channels (failed - server expects client to create)
+- No improvement
+
+## Analysis
+
+The identical failure in both native and WebView WebRTC implementations suggests the issue is:
+
+1. **Server-side** - Different handling of ma-api vs sendspin channels
+2. **TURN relay** - High-traffic channel may hit limits
+3. **Not client-specific** - Both implementations fail identically
+
+### Questions for MA Team
+
+1. Are the two data channels (`ma-api`, `sendspin`) created with different settings?
+2. Is there any server-side buffering or rate limiting that could affect high-traffic channels?
+3. Does the MA Web UI use different data channel configurations?
+4. Are there known issues with the TURN relay for sustained high-traffic channels?
+
+## Comparison: MA Web UI vs Android App
+
+| Aspect | MA Web UI | Android App |
+|--------|-----------|-------------|
+| Platform | Browser tab (visible, active) | Background-capable app |
+| WebRTC | Browser native | flutter_webrtc / WebView |
+| Result | Works | Fails after 1-3 min |
+
+The MA Web UI runs in a **visible, active browser tab**. Android may throttle background apps differently, but this doesn't explain why sendspin survives while ma-api dies on the same connection.
+
+## Logs
+
+### Health Check Pattern (shows channel death)
+```
+07:14:25 API sent:51 recv:54, lastRecv:2s ago   <- Working
+07:15:35 API sent:87 recv:91, lastRecv:2s ago   <- Working
+07:16:05 API sent:108 recv:97, lastRecv:17s ago <- DYING (gap growing)
+07:16:15 API sent:114 recv:97, lastRecv:27s ago <- DEAD
+07:16:45 API sent:130 recv:97, lastRecv:27s ago <- Still sending, no receive
+07:17:30 API sent:137 recv:97, lastRecv:42s ago <- Forced reconnect
+```
+
+### Sendspin Still Working During Failure
+```
+07:16:17 Sendspin: Received server/time response  <- Still alive!
+07:16:47 Sendspin: Received server/time response  <- Still alive!
+```
+
+## Requested Information
+
+1. Data channel creation code/settings for both channels
+2. Any server-side differences in channel handling
+3. TURN server configuration details
+4. Whether this has been reported by other Android/mobile clients
+
+## Workaround
+
+Currently using local WebSocket connection when on same network. Remote access via WebRTC is unusable for sustained use.

+# Plan B: Single Data Channel Multiplexing
+
+## Why This Might Be Needed
+
+If upgrading flutter_webrtc doesn't fix the one-way channel failure, the root cause is likely a bug in how flutter_webrtc (or underlying libwebrtc) handles **multiple data channels**.
+
+Evidence:
+- MA Web UI works fine with local playback (same server, browser WebRTC)
+- Our app uses flutter_webrtc which has known issues:
+  - [Issue #1428](https://github.com/flutter-webrtc/flutter-webrtc/issues/1428): Threading issues causing data loss
+  - [Issue #974](https://github.com/flutter-webrtc/flutter-webrtc/issues/974): EventChannel intermittently fails
+- Pattern matches: second channel survives while first dies
+
+## Current Architecture
+
+```
+┌─────────────────────────────────────────────────┐
+│              WebRTC Peer Connection             │
+├────────────────────┬────────────────────────────┤
+│   ma-api channel   │     sendspin channel       │
+│   (JSON API)       │   (JSON + binary audio)    │
+│   SCTP stream 0    │     SCTP stream 1          │
+└────────────────────┴────────────────────────────┘
+```
+
+## Proposed Architecture
+
+```
+┌─────────────────────────────────────────────────┐
+│              WebRTC Peer Connection             │
+├─────────────────────────────────────────────────┤
+│              unified channel                     │
+│    (multiplexed: API + Sendspin text + binary)  │
+│              SCTP stream 0                       │
+└─────────────────────────────────────────────────┘
+```
+
+## Multiplexing Protocol
+
+### Message Framing
+
+Each message has a 1-byte type prefix:
+
+| Prefix | Type | Content |
+|--------|------|---------|
+| 0x00 | API | JSON text (MA API request/response) |
+| 0x01 | Sendspin Text | JSON text (Sendspin control messages) |
+| 0x02 | Sendspin Binary | Raw bytes (PCM audio data) |
+
+### Implementation
+
+#### Sending (Client → Server)
+
+```dart
+void sendApiMessage(String json) {
+  final prefix = Uint8List.fromList([0x00]);
+  final payload = utf8.encode(json);
+  final message = Uint8List(1 + payload.length);
+  message[0] = 0x00;
+  message.setRange(1, message.length, payload);
+  _dataChannel.send(RTCDataChannelMessage.fromBinary(message));
+}
+
+void sendSendspinText(String json) {
+  final prefix = Uint8List.fromList([0x01]);
+  final payload = utf8.encode(json);
+  final message = Uint8List(1 + payload.length);
+  message[0] = 0x01;
+  message.setRange(1, message.length, payload);
+  _dataChannel.send(RTCDataChannelMessage.fromBinary(message));
+}
+
+void sendSendspinBinary(Uint8List audio) {
+  final message = Uint8List(1 + audio.length);
+  message[0] = 0x02;
+  message.setRange(1, message.length, audio);
+  _dataChannel.send(RTCDataChannelMessage.fromBinary(message));
+}
+```
+
+#### Receiving (Server → Client)
+
+```dart
+void _onMessage(RTCDataChannelMessage message) {
+  final data = message.binary;
+  if (data == null || data.isEmpty) return;
+
+  final type = data[0];
+  final payload = data.sublist(1);
+
+  switch (type) {
+    case 0x00: // API
+      final json = utf8.decode(payload);
+      _handleApiMessage(json);
+      break;
+    case 0x01: // Sendspin text
+      final json = utf8.decode(payload);
+      _handleSendspinText(json);
+      break;
+    case 0x02: // Sendspin binary
+      _handleSendspinBinary(payload);
+      break;
+  }
+}
+```
+
+## Server-Side Changes Required
+
+The Music Assistant server would need to:
+1. Accept a single "unified" data channel instead of separate ma-api and sendspin channels
+2. Multiplex responses using the same framing protocol
+3. This requires changes to the MA remote connection code
+
+**Alternative**: Keep server unchanged, do multiplexing in a proxy layer on the client.
+
+## Client-Only Approach (No Server Changes)
+
+If we can't change the server, we could:
+
+1. Still create two channels to the server (ma-api + sendspin)
+2. But internally route them through a single "virtual" channel for flutter_webrtc
+3. This is more complex and may not avoid the underlying bug
+
+## Files to Modify
+
+| File | Changes |
+|------|---------|
+| `webrtc_connection.dart` | Single channel creation, multiplexing logic |
+| `remote_bridge.dart` | Route messages based on type prefix |
+
+## Risks
+
+1. **Server compatibility**: Requires MA server changes or complex client proxy
+2. **Performance**: Extra byte per message, decode overhead
+3. **Binary handling**: Must handle all messages as binary (not text)
+
+## Testing Plan
+
+1. Implement client-side changes
+2. Test with modified server (if available) or mock
+3. Verify both API and Sendspin traffic flows correctly
+4. Long-duration stability test
+
+## Decision Point
+
+Try this approach if:
+- flutter_webrtc 0.14.x doesn't fix the issue
+- The one-way failure pattern continues
+- We've confirmed the issue is multi-channel specific

+# WebRTC Data Channel Disconnect Fixes
+
+## Document Purpose
+Track all fixes attempted for the WebRTC data channel disconnection issues in Ensemble's remote connection feature. This document should be referenced when debugging future disconnection problems.
+
+---
+
+## Problem Summary
+
+The WebRTC data channel between the Ensemble mobile app and Music Assistant server can fail in several ways:
+
+1. **One-way failure**: Data channel appears "open" but only sends work, receives stop
+2. **Silent disconnect**: No error events fire, channel just stops working
+3. **ICE failure**: ICE connection fails, properly detected but causes disconnect
+4. **Signaling disconnect**: Signaling WebSocket closes, causing ICE/WebRTC to fail
+
+---
+
+## Key Files
+
+| File | Purpose |
+|------|---------|
+| `lib/services/remote/webrtc_connection.dart` | WebRTC peer connection, data channel management |
+| `lib/services/remote/remote_bridge.dart` | WebSocket bridge, health monitoring, reconnection logic |
+| `lib/services/remote/signaling_client.dart` | Signaling server WebSocket connection |
+
+---
+
+## Implemented Fixes (Chronological)
+
+### Fix 1: Data Channel Keepalive (Original)
+**Problem**: Data channel could silently die without any error events firing.
+
+**Solution**: Added periodic keepalive ping/pong on the data channel itself.
+
+**Code** (`webrtc_connection.dart`):
+- `_keepaliveTimer`: Runs every 10 seconds
+- `_checkKeepalive()`: Checks time since last data received
+- `_sendKeepalivePing()`: Sends JSON ping message
+- `_recordDataReceived()`: Called on every message receipt
+
+**Constants**:
+```dart
+static const _keepaliveInterval = Duration(seconds: 10);
+static const _keepaliveTimeout = Duration(seconds: 20);  // Reduced from 30
+static const _maxKeepaliveMisses = 2;  // Reduced from 3
+```
+
+### Fix 2: ICE Recovery
+**Problem**: ICE connection could temporarily disconnect and might auto-recover.
+
+**Solution**: Added ICE recovery timer before declaring failure.
+
+**Code** (`webrtc_connection.dart`):
+- `_startIceRecovery()`: Starts 5-second timer when ICE disconnects
+- `_cancelIceRecovery()`: Cancels if ICE recovers on its own
+- `_attemptIceRestart()`: Calls `restartIce()` if recovery timer expires
+
+### Fix 3: Flow Control (Buffer Overflow Prevention)
+**Problem**: Fire-and-forget sends could overflow the 16MB SCTP buffer, causing silent channel death.
+
+**Solution**: Added send-side flow control with buffering.
+
+**Code** (`webrtc_connection.dart`):
+```dart
+static const _maxBufferedAmount = 1048576;  // 1MB threshold
+static const _bufferLowThreshold = 65536;   // 64KB resume threshold
+bool _sendPaused = false;
+final _sendQueue = <String>[];
+```
+
+**Modified `sendRaw()`**:
+- Checks `bufferedAmount` before sending
+- Queues messages if buffer > 1MB
+- `onBufferedAmountLow` callback drains queue
+
+### Fix 4: Health Check Stale Detection
+**Problem**: Health check could see "30s since last data" but not trigger reconnection.
+
+**Solution**: Reduced stale detection threshold from 45s to 30s.
+
+**Code** (`remote_bridge.dart`):
+```dart
+if (_state == RemoteBridgeState.connected && timeSinceLastData > 30 && !_isReconnecting) {
+  // Force reconnection
+}
+```
+
+### Fix 5: Reduced Keepalive Timeouts
+**Problem**: 30s timeout × 3 misses = 90s minimum before detection.
+
+**Solution**: Reduced to 20s timeout × 2 misses = ~40s detection.
+
+### Fix 6: Recv Stagnation Detection
+**Problem**: One-way failure where recv stops but sent continues not detected quickly enough.
+
+**Solution**: Track recv count across health checks. If recv stuck while sent increases for 2 consecutive checks (20s), force reconnection.
+
+**Code** (`remote_bridge.dart`):
+```dart
+// Track across health checks
+int _lastHealthCheckRecvCount = 0;
+int _lastHealthCheckSentCount = 0;
+int _recvStagnationCount = 0;
+
+// In health check:
+if (recvStuck && sentIncreased) {
+  _recvStagnationCount++;
+  if (_recvStagnationCount >= 2) {
+    // Force reconnection - channel is one-way
+  }
+}
+```
+
+**Detection time**: ~20 seconds (2 × 10s health check interval)
+
+---
+
+## Log Patterns to Watch For
+
+### Healthy Connection
+```
+Health check - API sent:93 recv:88 ... lastRecv:0s ago
+```
+- `sent` and `recv` both increasing
+- `lastRecv` low (< 5s typically)
+
+### One-Way Failure (CRITICAL)
+```
+Health check - API sent:206 recv:163 ... lastRecv:30s ago
+Health check - API sent:218 recv:163 ... lastRecv:40s ago
+```
+- `sent` increases, `recv` STUCK
+- `lastRecv` keeps increasing
+- Data channel still shows "open"
+
+### Signaling Disconnect
+```
+WebRTC: Signaling disconnected
+... (6-16 seconds later) ...
+WebRTC: ICE connection state: RTCIceConnectionStateDisconnected
+WebRTC: ICE connection state: RTCIceConnectionStateFailed
+```
+
+### Network Failure (DNS)
+```
+Signaling: WebSocket closed
+... (reconnection attempt) ...
+Signaling: Failed to connect: SocketException: Failed host lookup: 'signaling.music-assistant.io'
+```
+This indicates the phone lost network connectivity entirely.
+
+### Reconnection Storm (Signaling Instability)
+```
+Signaling: Connecting to wss://signaling.music-assistant.io/ws
+Signaling: Sending connect-request
+Signaling: WebSocket closed  ← Closes within 100-500ms
+WebRTC: Signaling disconnected
+RemoteBridge: Scheduling reconnect attempt X/10 in Ys
+```
+Rapid reconnection loop - signaling never stays connected long enough.
+
+### Flow Control Engaged
+```
+WebRTC: ⚠️ Buffer full (1234567 bytes) or paused - queueing message
+WebRTC: Buffer drained to 12345 bytes - draining 5 queued messages
+WebRTC: ✅ Send queue drained (5 messages) - resuming normal sends
+```
+
+### Keepalive Detection
+```
+WebRTC: ⚠️ Keepalive timeout! No data for 22s (missed: 1/2)
+WebRTC: ❌ Data channel appears dead - triggering reconnection
+```
+
+---
+
+## Known Issues / Limitations
+
+### 1. flutter_webrtc Limitations
+- `RTCDataChannel.state` may show "open" when actually dead (Issue #843)
+- `bufferedAmount` may not be accurate on all platforms
+- `onBufferedAmountLow` callback support varies
+
+### 2. SCTP Receive Window
+- If server sends faster than client processes, receive window fills
+- This causes server-side to stop sending, client sees no data
+- No way to monitor receive-side buffer from client
+
+### 3. TURN Server Issues
+- aiortc (server-side) has known issues with TURN + DataChannel (#1156)
+- Data channel may fail silently when using TURN relay
+
+### 4. Network Transitions
+- WiFi → Cellular or vice versa can cause ICE to fail
+- App backgrounding on mobile can close WebSocket/WebRTC
+
+---
+
+## Root Cause Categories
+
+### Category A: Network Issues (Not Code Bugs)
+These are environmental issues, not bugs in our code:
+- **DNS failure**: `Failed host lookup` - Phone lost internet
+- **WiFi/Cellular switch**: Network changed, connections dropped
+- **Server unreachable**: Signaling server down or blocked
+- **Firewall/NAT issues**: TURN relay needed but unavailable
+
+**Evidence**: Signaling WebSocket closes, DNS lookups fail, reconnection attempts fail repeatedly.
+
+### Category B: WebRTC/SCTP Issues (Partial Code Control)
+These can be mitigated but not fully prevented:
+- **One-way channel death**: Channel appears open but data stops flowing
+- **Buffer overflow**: Too much data sent, SCTP buffer exceeded
+- **ICE failure**: Network path lost, no recovery possible
+
+**Evidence**: Data channel shows "open" but `recv` stuck, `lastRecv` increasing.
+
+### Category C: Code Bugs (Fixable)
+Issues in our implementation:
+- **Detection too slow**: Timeouts too long, misses too many
+- **Recovery not triggered**: State checks wrong, reconnection not started
+- **Resource leaks**: Timers not cancelled, connections not cleaned up
+
+**Evidence**: Logs show problem but no action taken, or wrong action taken.
+
+---
+
+## Debugging Checklist
+
+When investigating a disconnect:
+
+1. **Find the last successful response**:
+   ```
+   grep "WebRTC API → WS" logs.txt | head -5
+   ```
+
+2. **Check health check progression**:
+   ```
+   grep "Health check" logs.txt
+   ```
+   Look for `recv` getting stuck while `sent` increases.
+
+3. **Check for signaling issues**:
+   ```
+   grep -i "signaling" logs.txt
+   ```
+
+4. **Check ICE state changes**:
+   ```
+   grep "ICE connection state" logs.txt
+   ```
+
+5. **Check for keepalive detection**:
+   ```
+   grep -i "keepalive" logs.txt
+   ```
+
+6. **Check buffer status**:
+   ```
+   grep -E "(buffer|queue|paused)" logs.txt
+   ```
+
+---
+
+## Potential Future Improvements
+
+### 1. Server-Side Backpressure
+MA protocol doesn't have explicit backpressure. Could add:
+- Client-side request throttling
+- Application-level ACKs for critical messages
+
+### 2. More Aggressive Detection
+- Track recv count across health checks, detect stagnation
+- Shorter keepalive interval (5s instead of 10s)
+
+### 3. Proactive Health Signals
+- Monitor `bufferedAmount` trend (increasing = problem)
+- Track round-trip latency of keepalive pings
+
+### 4. Connection Quality Metrics
+- Expose packet loss, jitter from WebRTC stats
+- Use to predict imminent failure
+

+
+## Test Scenarios
+
+| Scenario | How to Test | Expected Behavior |
+|----------|-------------|-------------------|
+| Normal usage | Browse library, play music | No warnings |
+| Heavy sync | Pull-to-refresh library | Buffer may queue, should drain |
+| Long session | Leave connected 2+ hours | Should stay connected |
+| Rapid navigation | Quick tab switching | Brief queue usage, recovers |
+| Network change | WiFi → Cellular | Should detect and reconnect |
+| App background | Background for 5+ min | May disconnect, should reconnect |
+
+---
+
+## Observed Failure Patterns
+
+### Pattern 1: One-Way Death After Library Sync
+**Observed**: 2026-01-23 (multiple times)
+
+```
+17:13:06.175 - Last response (playlists sync)
+17:13:06.264 - Local batch save
+-- 5 seconds silence --
+17:13:11.005 - Send players/all → NO RESPONSE
+17:13:13.914 - ICE state: completed (looks healthy!)
+17:13:28 - Keepalive detects timeout
+17:13:38 - Reconnection triggered
+```
+
+**Characteristics**:
+- Often happens after library sync (large batch responses)
+- ICE shows "completed" even though data channel is dead
+- Signaling ping/pong continues working
+- Only data channel receive is affected
+
+**Hypothesis**:
+- Server-side SCTP buffer exhausted from sending large responses?
+- Client receive window full, server blocks?
+- flutter_webrtc onMessage callback stops firing?
+
+### Pattern 2: Reconnection Storm / Signaling Instability
+**Observed**: 2026-01-23 17:30-17:31
+
+```
+17:31:05.093 - Signaling: Connecting
+17:31:05.216 - Signaling: Sending connect-request
+17:31:05.218 - Signaling: WebSocket closed (123ms later!)
+17:31:05.218 - WebRTC: Signaling disconnected
+```
+
+**Characteristics**:
+- Signaling WebSocket closes almost immediately after connect
+- Multiple rapid reconnection attempts (storm)
+- Connection never stable long enough for data flow
+- Often happens after network instability
+- Artist detail, albums etc don't load because connection keeps failing
+
+**Possible Causes**:
+- Network instability (WiFi/cellular issues)
+- Signaling server rate limiting
+- DNS resolution failures
+- Server rejecting rapid reconnection attempts
+
+**Side Effects**:
+- UI shows errors like "Not connected to Music Assistant server"
+- Artist/album detail screens fail to load
+- Players list empty or stale
+
+### Pattern 3: API Channel Dies While Sendspin Lives
+**Observed**: 2026-01-23 17:53
+
+```
+17:53:35.755 - Send album_tracks request → NO RESPONSE
+17:53:40.596 - Health check: recv stuck at 197, sent increased
+17:53:55.204 - Sendspin channel RECEIVES server/time response!
+17:54:02.790 - Keepalive detects dead API channel
+```
+
+**Characteristics**:
+- API data channel (ma-api) stops receiving
+- Sendspin data channel continues working normally
+- Same WebRTC peer connection, different data channels
+- This proves it's NOT a network issue - Sendspin traffic flows fine
+
+**Hypothesis**:
+- flutter_webrtc bug where `onMessage` callback stops firing for one channel
+- Possible memory/GC issue with the callback
+- Server-side might be sending to wrong channel?
+
+**Key Evidence**:
+- Recv count stays at 197 for API
+- Sendspin recv count increases (7→8)
+- Both channels use same peer connection

+# WebRTC Remote Connection Progress
+
+## Problem Statement
+The flutter_webrtc library has reliability issues causing data channel failures during remote connections via Nabu Casa. The ma-api data channel becomes one-way (can send, but receives stop) after some time, while the sendspin channel continues working.
+
+## Approaches Tried
+
+### 1. Original Implementation (flutter_webrtc)
+- **Status**: Fails
+- **Issue**: ma-api data channel goes one-way after some time
+- **Files**: `lib/services/remote/webrtc_connection.dart`
+
+### 2. WebView-based WebRTC Implementation
+- **Status**: Same failure mode
+- **Hypothesis**: Use browser-native WebRTC via InAppWebView, since MA Web UI works
+- **Result**: Same one-way channel death occurs
+- **Key Finding**: This proves the issue is NOT specific to flutter_webrtc
+
+## Key Observations
+
+From the logs:
+```
+lastRecv:26s ago          <- No messages received in 26 seconds
+API sent:674 recv:618     <- Gap growing, responses stopped
+```
+
+- Signaling ping/pong continues working
+- Sendspin channel continues receiving (`server/time` responses)
+- Only ma-api channel becomes one-way
+- WebRTC peer connection itself remains "connected"
+
+## Differences from Working MA Web UI
+
+The MA Web UI runs in a **visible, active browser tab**. Our implementations:
+1. flutter_webrtc: Native WebRTC in background app
+2. WebView: Browser WebRTC in **hidden 1x1 pixel WebView**
+
+Android aggressively throttles hidden WebViews to save battery.
+
+## Current Implementation (WebView)

+
+## Current Fixes Being Tested
+
+### 1. Prevent WebView Throttling
+- Changed WebView position from off-screen (-10,-10) to on-screen (0,0) with Opacity(0)
+- Added various InAppWebViewSettings to prevent background throttling
+
+### 2. Data Channel Settings
+- Changed from `ordered: true` to `ordered: false` with `maxRetransmits: 3`
+- Hypothesis: Ordered delivery may cause buffer bloat issues
+
+### 3. Buffer Monitoring
+- Added `bufferedAmount` checking in JavaScript
+- Logs warning when buffer exceeds 1MB
+- Added `getChannelHealth()` function for diagnostics
+
+### 4. Reduced Logging
+- Removed per-message logging (was filling logs too fast)
+- Keep only state changes, errors, and warnings
+
+## Experiments Completed
+
+### 5. Server-Created Channels (Failed)
+- **Hypothesis**: Let server create data channels to avoid ID collisions
+- **Result**: Connection timeout - server expects CLIENT to create channels
+- **Learning**: Client must create channels before sending offer
+
+## Next Steps to Try
+
+1. **Make WebView actually visible** - Android may still throttle Opacity(0) WebView
+2. **Single data channel** - Use only ma-api, disable sendspin
+3. **Periodic channel recreation** - Detect stale channel and recreate
+4. **Report to MA team** - Browser WebRTC also fails, suggesting server-side issue
+
+## Test APK Location
+`/home/chris/Ensemble/ensemble-webview-webrtc.apk`
+
+## Useful Debug Commands
+
+Check channel health (in JS console or via Dart):
+```javascript
+getChannelHealth()
+// Returns: { peerConnection, iceConnection, apiChannel, apiBuffered, sendspinChannel, sendspinBuffered, signalingConnected }
+```
+
+## Open Questions
+
+1. Why does sendspin channel survive when ma-api dies?
+2. Is there a difference in how MA server handles the two channels?
+3. Does MA Web UI use different data channel settings?
+4. Is there a TURN relay issue specific to high-traffic channels?
