+# 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

+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)

-# Ensemble Flutter App - Code Audit Report
+# Ensemble Codebase Audit Report

-**Date:** January 4, 2026
-**Branch:** `audit/code-quality-review`
-**Files Audited:** 93 Dart files
+**Date**: 2026-01-14
+**Scope**: Full codebase audit (104 Dart files, 18 screens)
+**Focus Areas**: UI Continuity, Performance, Logic/Best Practices

 ---

 ## Executive Summary

-The codebase is generally well-maintained with good existing performance optimizations (RepaintBoundary, ListView.builder, cacheExtent settings). Key improvement areas identified:
+The Ensemble codebase is a **mature, feature-rich Flutter application** with many good patterns already in place. However, the audit identified **significant architectural debt** that should be addressed:

-| Category | Issues Found | Priority |
-|----------|-------------|----------|
-| Deprecated APIs | 20 instances | HIGH |
-| Missing const constructors | 100+ instances | MEDIUM |
-| Image cache parameters | 7 locations | MEDIUM |
-| Code duplication | 8 view mode functions | LOW |
-| Color constants | 3 files with duplicates | LOW |
+| Severity | Count | Key Themes |
+|----------|-------|------------|
+| **Critical** | 6 | God classes (5,443 & 4,209 lines), design token adoption, startup blocking |
+| **High** | 15 | Touch targets, batch DB operations, over-notification, code duplication |
+| **Medium** | 25+ | Inconsistencies, memory issues, missing error boundaries |
+| **Low** | 15+ | Minor polish items |
+
+**Top 3 Priorities:**
+1. **Split `MusicAssistantProvider` (5,443 lines)** - God object handling everything
+2. **Split `new_library_screen.dart` (4,209 lines)** - 10 scroll controllers, 15+ view modes
+3. **Fix startup performance** - Sequential blocking ops could save 1-8 seconds

 ---

-## 1. CRITICAL: Deprecated API Usage
+## Critical Issues

-### `colorScheme.background` (20 instances)
-Flutter Material 3 deprecates `ColorScheme.background`. Replace with `colorScheme.surface`.
+### 1. God Object: MusicAssistantProvider (5,443 lines)
+**File**: `lib/providers/music_assistant_provider.dart`
+- 54 `notifyListeners()` calls
+- 30+ state variables
+- 100+ public methods
+- Handles: connection, auth, players, library, search, caching, local playback, Sendspin
+- **Fix**: Split into ConnectionManager, PlayerStateManager, LibraryStateManager, SearchStateManager

-**Files affected:**
- lib/main.dart:335, 336
- lib/screens/library_artists_screen.dart:21
- lib/screens/new_home_screen.dart:121
- lib/screens/artist_details_screen.dart:708, 720
- lib/screens/library_playlists_screen.dart:53
- lib/screens/library_tracks_screen.dart:19
- lib/screens/login_screen.dart:489

- lib/screens/album_details_screen.dart:807, 819
- lib/screens/library_albums_screen.dart:19
- lib/screens/search_screen.dart:427, 738, 739
- lib/screens/settings_screen.dart:245
+### 2. God Object: NewLibraryScreen (4,209 lines)
+**File**: `lib/screens/new_library_screen.dart`
+- 10 scroll controllers
+- 15+ view mode states
+- 15+ sort order states
+- Handles: Music, Books, Podcasts, Radio tabs
+- **Fix**: Extract to ArtistsTab, AlbumsTab, TracksTab, PlaylistsTab, BooksTab, PodcastsTab, RadioTab
+
+### 3. Sequential Blocking Startup (500-1500ms wasted)
+**File**: `lib/main.dart:33-66`
+```dart
+await DatabaseService.instance.initialize();
+await ProfileService.instance.migrateFromOwnerName();
+await SettingsService.migrateToSecureStorage();
+await SyncService.instance.loadFromCache();
+audioHandler = await AudioService.init(...);
+```
+- **Fix**: Parallelize with `Future.wait()`, defer AudioService to post-first-frame
+
+### 4. Design Tokens Exist But Unused
+**File**: `lib/theme/design_tokens.dart`
+- `Spacing.*` used in only ~6 of 34+ widget files
+- `Radii.*` used in only ~5 files
+- `IconSizes.*` used in only ~4 files
+- **Fix**: Systematic replacement of hardcoded values
+
+### 5. Touch Targets Too Small (32x32)
+**File**: `lib/screens/new_library_screen.dart:1805-1867`
+- Sort, favorites, view mode buttons are 32x32
+- Material Design minimum: 48x48
+- **Fix**: Increase to 48x48 or add padding for hit area
+
+### 6. No Batch Database Inserts
+**File**: `lib/services/sync_service.dart:212-273`
+- 1000 albums = 1000 separate DB transactions
+- **Fix**: Wrap in single transaction or use Drift batch insert

-## 2. HIGH: Missing const Constructors
+## High Severity Issues

-### EdgeInsets.zero (64 instances)
-High-impact optimization - used extensively in button padding.
+### Performance
+| Issue | File | Impact |
+|-------|------|--------|
+| `context.watch()` in nested tabs | new_library_screen.dart:2960 | All tabs rebuild on any provider change |
+| Consumer wrapping 800-line player | expandable_player.dart:1234 | Full rebuild on every state change |
+| Inline sorting during build | new_library_screen.dart:3647 | 5-20ms for 1000+ albums |
+| Multiple setState for author images | new_library_screen.dart:1017 | 20+ rebuilds as images load |

-## 3. MEDIUM: Scroll Performance - Missing Image Cache Parameters
+## Medium Severity Issues

-### CachedNetworkImage without memCacheWidth/Height
+### Performance
+- PaletteGenerator on main isolate (10-30ms blocking)
+- Multiple `SharedPreferences.getInstance()` calls (132 occurrences)
+- AppStartup polling loop with fixed 250ms delay
+- SystemThemeHelper FutureBuilder recreated on every build

-**lib/screens/new_library_screen.dart:**
- Line 1395-1402: Author image (48x48) - missing cache params
- Line 1480-1486: Author card image - missing cache params
- Line 1572-1580: Audiobook cover (56x56) - missing cache params
- Line 1740-1745: Audiobook grid cover - missing cache params
- Line 1959-1969: Playlist cover (56x56) - missing cache params
- Line 2143-2152: Playlist grid covers - missing cache params
- Line 2973-2981: Album cover (56x56) - missing cache params
+### UI Consistency
+- Border radius varies: 8, 12, 20, 22, 25 for same element types
+- `SizedBox(height: 8)` appears 40+ times instead of `Spacing.vGap8`
+- Hardcoded colors for status (Colors.red, Colors.green)
+- Inconsistent icon sizes across screens

-**Note:** DecorationImage with CachedNetworkImageProvider cannot have cache size specified (structural Flutter limitation).
+### State Management
+- Over-notification (multiple notifyListeners in single methods)
+- Wide Consumer scope (watch instead of select)
+- Missing dispose() in some providers
+- Inconsistent async state handling (loading/error)
+
+### Navigation
+- `isQueuePanelOpen` vs `isQueuePanelTargetOpen` inconsistency
+- `popToHome()` doesn't clear adaptive colors
+- Infinite navigation loop possible (Album → Artist → Album)
+- Orphaned Hero animations in podcast_card, radio_station_card
+
+### Data/Caching
+- Unbounded `_podcastCoverCache`
+- SyncService listener not removed on error
+- Redundant API calls between providers
+- Fire-and-forget persistence race condition
+
+### Error Handling
+- No zone error handler for async exceptions
+- `retryCritical()` retries all errors including non-recoverable
+- No user notification of offline queue status
+- DisconnectedState not used consistently

 ---

-## 4. LOW: Code Duplication
+## Quick Wins (High Impact, Low Effort)

-### View Mode Cycling Functions (8 nearly identical functions)
-**File:** lib/screens/new_library_screen.dart
-
-Functions that follow identical switch/case pattern:
- `_cycleArtistsViewMode()` (line 184)
- `_cycleAlbumsViewMode()` (line 200)
- `_cyclePlaylistsViewMode()` (line 216)
- `_cycleAuthorsViewMode()` (line 232)
- `_cycleAudiobooksViewMode()` (line 248)
- `_cycleSeriesViewMode()` (line 286)
- `_cycleRadioViewMode()` (line 303)
- `_cyclePodcastsViewMode()` (line 319)
-
-**Recommendation:** Create generic utility function.
-
-### Duplicated Color Constants (3 files)
-Series fallback colors defined identically in:
- lib/widgets/series_row.dart:246-253
- lib/screens/audiobook_series_screen.dart:466-473
- lib/screens/new_library_screen.dart:2112-2119
-
-**Recommendation:** Extract to lib/constants/colors.dart
+| # | Task | File(s) | Effort |
+|---|------|---------|--------|
+| 1 | Replace hardcoded bottom spacing with `BottomSpacing.withMiniPlayer` | Detail screens | 30 min |
+| 2 | Add navigation debounce to card widgets | album_card, artist_card, etc. | 1 hr |
+| 3 | Fix touch targets to 48x48 minimum | new_library_screen.dart | 15 min |
+| 4 | Add migration skip flag for SecureStorage | secure_storage_service.dart | 30 min |
+| 5 | Add Flutter error boundary | main.dart | 30 min |
+| 6 | Use `context.select()` instead of `context.watch()` | global_player_overlay, etc. | 2 hr |
+| 7 | Cache `SharedPreferences.getInstance()` | settings_service.dart | 30 min |

 ---

-## 5. POSITIVE FINDINGS (Already Optimized)
+## Refactoring Roadmap

- **RepaintBoundary**: Properly implemented in all list item widgets
- **ListView.builder**: Used consistently with cacheExtent: 1000
- **ScrollController disposal**: All 8+ controllers properly disposed
- **Animation patterns**: Proper listener cleanup in expandable_player.dart
- **Debounced operations**: Color extraction debounced to 300ms
+### Phase 1: Quick Wins (1-2 days)
+- Fix touch targets
+- Fix bottom spacing
+- Add navigation debounce
+- Add error boundaries
+- Cache SharedPreferences singleton
+
+### Phase 2: Performance (3-5 days)
+- Parallelize startup operations
+- Replace `context.watch()` with `context.select()`
+- Batch database inserts
+- Add SecureStorage migration skip flag
+- Fix over-notification in provider
+
+### Phase 3: Design System (1 week)
+- Systematic design token adoption
+- Standardize button sizes (44 vs 50)
+- Standardize border radius values
+- Create StatusColors semantic tokens
+- Replace all magic numbers
+
+### Phase 4: Architecture (2-3 weeks)
+- ~~Split MusicAssistantProvider into focused managers~~ **DEFERRED** - MusicAssistantProvider has evolved with Sendspin, Cast-Sendspin ID mapping, position tracker integration. Splitting would require ~1600 lines of sync work. Code is working and tested.
+- ~~Split new_library_screen into tab widgets~~ **DEFERRED** - Tabs have tight state coupling (15+ view modes, 15+ sort orders, 10 scroll controllers). Extraction would require InheritedWidget/callbacks for all shared state. Risk outweighs benefit.
+- ✅ Extract generic helpers for SettingsService - Reduced from 1,031 to 874 lines (~15%)
+- ✅ Remove/integrate unused providers - Deleted PlayerProvider (964 lines), LibraryProvider, ConnectionProvider (651 lines total)
+- ~~Split music_assistant_api.dart by domain~~ **DEFERRED** - All methods share WebSocket connection and auth state. Clean extraction would require connection manager abstraction.

 ---

-## Recommended Action Plan
+## Positive Findings

-### Phase 1: Quick Wins (Low Risk)
-1. Replace `colorScheme.background` with `colorScheme.surface` (20 locations)
-2. Add `const` to EdgeInsets.zero instances
+The codebase already demonstrates many good practices:

-### Phase 2: Image Optimization
-1. Add memCacheWidth/memCacheHeight to CachedNetworkImage instances in new_library_screen.dart
-
-### Phase 3: Code Cleanup (Optional)
-1. Extract view mode cycling to utility function
-2. Centralize color constants
+- **Performance awareness**: `// PERF:` comments, RepaintBoundary (55 occurrences), image caching (80 memCacheWidth/Height)
+- **Caching**: Multi-tier caching with LRU eviction, proper TTLs, proper DB indexes
+- **Error handling**: DebugLogger, RetryHelper, OfflineActionQueue well-implemented
+- **Theme system**: Material You support, adaptive colors from album art
+- **Offline support**: Cache-first loading, graceful degradation
+- **Navigation**: Consistent FadeSlidePageRoute, proper Hero animations (mostly)

+
+---
+
+## Audit Methodology
+
+This audit was conducted using 9 parallel sub-agents analyzing:
+
+**UI Continuity (3 agents)**
+1. Navigation & Flow - back button, Hero animations, tab preservation
+2. Visual Consistency - design tokens, spacing, typography
+3. Component Placement - touch targets, bottom spacing, modals
+
+**Performance (3 agents)**
+4. Rendering Performance - ListView.builder, const, rebuilds
+5. Data & Caching - streams, invalidation, memory bounds
+6. Startup & Load Time - blocking operations, initialization order
+
+**Logic/Best Practices (3 agents)**
+7. State Management - Provider patterns, notification frequency
+8. Error Handling - try-catch, boundaries, resilience
+9. Code Quality - file size, duplication, SOLID principles
+
+---
+
+## Conclusion
+
+The Ensemble app is well-architected at the macro level but has accumulated technical debt in its largest files. The most impactful improvements would be:
+
+1. **Splitting the two 4,000+ line files** into focused components
+2. **Adopting design tokens systematically** for visual consistency
+3. **Optimizing startup sequence** for faster app launch
+4. **Using granular state management** (select vs watch) for better performance
+
+The quick wins section provides immediate value with minimal risk, while the roadmap offers a path to sustainable improvement.

+# 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);
+}
+```

+
+## 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
+

+# 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
+
+## MA API Reference
+
+### Get Providers
+```
+Command: providers
+Returns: List of provider instances with type, domain, instanceId, name, available
+```
+
+### Library Items with Filter
+```
+Command: music/artists/library_items
+Args: {
+  limit: int,
+  offset: int,
+  provider: string | list<string>,  // Filter to specific provider(s)
+  album_artists_only: bool,
+  order_by: string
+}
+```
+
+### 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 = {

+  '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).
+
+---

+
+## 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
+
+- [x] Music tabs filter by provider correctly
+- [x] Provider menu shows only relevant providers per category
+- [x] Radio providers don't appear in Artists/Albums tabs
+- [x] Spotify appears in Audiobooks tab (has audiobooks)
+- [x] Audiobooks Authors tab filters by provider
+- [x] Audiobooks All Books tab filters by provider
+- [ ] Audiobooks Series tab filters by provider (not implemented)
+- [x] Disabled providers can be re-enabled from menu
+- [x] Settings screen no longer has provider toggles

+# 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 From Here (track context menu)
+- [ ] Album details: Play Radio (track context menu)
