Replace in-memory list merging in the queue tab with fully database-
backed pagination using ATTACH DATABASE to join library and history
tables in a single UNION ALL query.
Queue tab:
- Remove localLibraryAllItemsProvider and _queueHistoryStatsProvider
- Add _queueLibraryPageProvider and _queueLibraryCountsProvider backed
by LibraryDatabase.getQueueTrackPage/getQueueCounts/getQueueAlbumPage
- Implement infinite scroll via _handleLibraryScrollNotification with
_libraryPageLimit growing by 300 per batch
- Album/single/total counts computed via SQL GROUP BY aggregates
History database (v5 -> v8):
- v6: add idx_history_track_artist index
- v7: add history_path_keys table for cross-DB dedup, backfill from
existing rows
- v8: add spotify_id_norm, isrc_norm, match_key normalized columns
with indexes, backfill from existing data
- Add getAlbumTracks, findByTrackAndArtist, getGroupedCounts,
existsTrack, findExistingTrack, existingTrackKeys batch lookup
- deleteBySpotifyId now returns deleted count for accurate totalCount
- All write paths maintain history_path_keys consistency
Library database (v7 -> v8):
- v8: add library_path_keys table for cross-DB dedup
- Add getQueueTrackPage, getQueueCounts, getQueueAlbumPage with
ATTACH DATABASE for cross-DB UNION ALL queries
- Dedup local items against history via path_keys JOIN
- All write/delete paths maintain library_path_keys consistency
Download history provider:
- Load only 100 recent items into state.items at startup
- Store lookupItems as immutable List field instead of recomputing
from maps on every access
- Add async fallback to DB in _putInMemoryHistory for items outside
the 100-item window
- Add downloadHistoryPageProvider, downloadHistoryGroupedCountsProvider,
downloadedAlbumTracksProvider, downloadHistoryBatchExistsProvider
- Add catchError to adoptNativeHistoryItem async block
- Fix removeBySpotifyId to query actual DB count instead of decrement
Screen migrations:
- album/artist/playlist/home screens use async DB lookups instead of
sync in-memory state for track existence and playback resolution
- downloaded_album_screen uses downloadedAlbumTracksProvider
- library_tracks_folder_screen uses downloadHistoryBatchExistsProvider
for skip-downloaded checks and cover resolution
Replace the full in-memory List<LocalLibraryItem> in LocalLibraryState
with a lightweight lookup index (ISRCs, matchKeys, filePathById) and
database-backed FutureProvider.family pagination providers.
Database changes:
- Add library schema v7 with normalized lookup columns (track_name_norm,
artist_name_norm, album_name_norm, album_artist_norm, match_key,
album_key) and corresponding indexes
- Backfill normalized columns on migration from v6
- Add getPage, getPageCount, getAlbumPage, getAlbumCount, getLookupIndex,
getCoverPaths, getByFilePath, findFirstByTrackAndArtist DB methods
Provider changes:
- LocalLibraryState no longer holds items list; uses totalCount and
loadedIndexVersion for change tracking
- Deprecate synchronous getByIsrc/findByTrackAndArtist (return null);
add async findExistingAsync, getByIsrcAsync, getById on notifier
- Add localLibraryPageProvider, localLibraryAlbumPageProvider,
localLibraryAllItemsProvider family providers for paginated access
- Add localLibraryCoverProvider and localLibraryFirstCoverProvider
for async cover path resolution from DB
Screen migrations:
- album/artist/playlist screens use findExistingAsync for playback
- library_tracks_folder_screen uses async cover providers and
existsInLibrary for local library indicator
- queue_tab watches localLibraryAllItemsProvider instead of state.items
- library_settings_page uses state.totalCount
- playback_provider uses findExistingAsync
Track metadata screen:
- Replace pushReplacement navigation with in-place state swap using
AnimatedSwitcher for smooth cross-fade transitions on track swipe
- Add metadataLoadGeneration counter to prevent stale async callbacks
- Reset all transient state (lyrics, cover, file check) on track change
Resolve API (api.zarz.moe):
- Refactor songlink.go: Spotify URLs use resolve API, non-Spotify uses SongLink API
- Add SongLink fallback when resolve API fails for Spotify (two-layer resilience)
- Remove dead code: page parser, XOR-obfuscated keys, legacy helpers
Multi-artist tag fix (#288):
- Add RewriteSplitArtistTags() in Go to rewrite ARTIST/ALBUMARTIST as split Vorbis comments
- Wire method channel handler in Android (MainActivity.kt) and iOS (AppDelegate.swift)
- Add PlatformBridge.rewriteSplitArtistTags() in Dart
- Call native FLAC rewriter after FFmpeg embed when split_vorbis mode is active
- Extract deezerTrackArtistDisplay() helper to use Contributors in album/playlist tracks
Code cleanup:
- Remove unused imports, dead code, and redundant comments across Go and Dart
- Fix build: remove stale getQobuzDebugKey() reference in deezer_download.go
- Defer extension VM initialization until first use with lockReadyVM() pattern to eliminate TOCTOU races and reduce startup overhead
- Add validateExtensionLoad() to catch JS errors at install time without keeping VM alive
- Teardown VM on extension disable to free resources; re-init lazily on re-enable
- Replace full orphan cleanup with incremental cursor-based pagination across launches
- Batch DB writes (upsertBatch, replaceAll) with transactions for atomicity
- Parse JSON natively on Kotlin side to avoid double-serialization over MethodChannel
- Add identity-based memoization caches for unified items and path match keys in queue tab
- Use ValueListenableBuilder for targeted embedded cover refreshes instead of full setState
- Extract shared widgets (_buildAlbumGridItemCore, _buildFilterButton, _navigateWithUnfocus)
- Use libraryCollectionsProvider selector and MediaQuery.paddingOf for fewer rebuilds
- Simplify supporter chip tiers and localize remaining hardcoded strings
- Reduce polling interval from 800ms to 1200ms across download progress, library scan, and Android native stream
- Add dirty-flag caching to Go GetMultiProgress() to skip redundant JSON marshaling
- Replace eager provider initialization with staggered Timer-based warmup (400/900/1600ms)
- Add snapshot-based incremental library scan to avoid large MethodChannel payloads
- Move history stats and grouped album filtering to Riverpod providers for better cache invalidation
- Cap home tab history preview to 48 items with deep equality wrapper to reduce rebuilds
- Throttle foreground service notification updates to 2% progress buckets
- Migrate PageView to PageView.builder with AutomaticKeepAliveClientMixin
- Add comparison table to README
Add set/get/clear store registry URL method channel handlers on Android,
iOS, and Go backend so users can configure a custom extension repository.
Store tab now shows a setup screen when no registry URL is configured,
with a cleaner layout (removed redundant description and helper text)
and visible TextField borders for dark theme.
Minor comment and formatting cleanups across several files.
- Add multi-select support to library_tracks_folder_screen (wishlist, loved,
playlist) with long-press to enter selection mode, animated bottom bar with

- Add Genre/Label/Copyright fields to DownloadResult struct
- buildDownloadSuccessResponse now prefers service result metadata over request
- enrichRequestExtendedMetadata fetches Deezer metadata by ISRC before download
