The HIGH-quality lossy format picker can now produce an AAC/M4A 320 kbps output alongside MP3 and Opus. FFmpegService.convertM4aToLossy/convertAudioFormat, the Dart queue pipeline, the Kotlin finalizer, and the library database format helper all route .m4a through a unified aac codec path and tag the resulting file with the M4A metadata writer. The Lossy Format setting gains a new option, and the track metadata convert dialog lists AAC next to the other targets.
Apple Music lyrics gain a 'eLRC word sync' switch (default off). When disabled the pax-to-LRC formatter strips inline word timestamps, producing line-synced LRC that is safer for players that choke on eLRC; enabling it restores the previous word-by-word behaviour. The change propagates through SetLyricsFetchOptions and invalidates the global lyrics cache on toggle.
Broad l10n migration: roughly 400 previously hardcoded English strings across queue, settings, track metadata, repo, audio analysis, setup and extension screens now live in the ARB catalog, with matching plural/placeholder forms. No behaviour change beyond localisation. Existing and new unit tests (lyrics eLRC toggle and Dart settings round-trip) pass.
Bump the history schema on both the Kotlin finalizer and the Dart database to v9, adding bitrate (kbps) and format (codec label) columns, and let the download flow fill them from backend/probe metadata so lossy downloads keep a 'AAC 256kbps' label instead of falling back to the stored placeholder. Library filtering and the track metadata screen now read format/bitrate directly from those columns, which also fixes mis-tagged quality badges after re-downloading a track at a different format.
Additional fixes bundled in: EditFileMetadata now routes ReplayGain writes through the M4A path whenever the file starts with ftyp (fixing .flac files that actually hold MP4 containers); GetM4AQuality falls back to the first trak/mdia/mdhd duration when mvhd is zero so EAC3 streams no longer report 0s; and both Kotlin and Dart reject bitrate values below 16 kbps to prevent probe noise from surfacing as '0 kbps' labels. New unit tests cover the EAC3 mdhd fallback and the mis-named M4A replaygain path.
GetM4AQuality now recognizes fLaC, alac, ec-3, ac-3, and ac-4 sample entries and parses the MP4 FLACSpecificBox so library entries carry the real codec rather than the container extension. The AudioQuality struct exposes Codec and Bitrate fields (with an estimator for compressed streams), and ReadFileMetadata publishes format + audio_codec so Flutter and Kotlin can make format decisions based on the actual stream.
Downstream: library_scan labels M4A-family items as flac/alac/eac3/ac3/ac4/m4a, zeroes the bitrate for lossless formats, and the filter UI + quality badges use the codec-derived format instead of only the file extension. Scans and SAF importers also accept .mp4 and .aac file extensions. New unit tests cover codec name mapping and MP4 FLACSpecificBox decoding.
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

with indexes, backfill from existing data
- Add getAlbumTracks, findByTrackAndArtist, getGroupedCounts,
existsTrack, findExistingTrack, existingTrackKeys batch lookup
- deleteBySpotifyId now returns deleted count for accurate totalCount

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

for skip-downloaded checks and cover resolution

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

localLibraryAllItemsProvider family providers for paginated access

existsInLibrary for local library indicator
- queue_tab watches localLibraryAllItemsProvider instead of state.items
- library_settings_page uses state.totalCount
- playback_provider uses findExistingAsync

- 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
