- Re-enrich: reject candidates that don't match title/artist/album unless exact ISRC match
- Respect settings.embedLyrics instead of hardcoding true in re-enrich flows
- Skip lyrics resolution in NativeDownloadFinalizer when not needed
- Apple Music lyrics: use direct catalog API with token scraping instead of Paxsenix search
- Support ELRC/ELRCMultiPerson/Plain formats in Apple Music lyrics response
- Add confidence check in metadata auto-fill to prevent applying wrong metadata
- Add tests for stricter re-enrich matching logic
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.
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

- Extract PrioritySettingsScaffold widget from lyrics and metadata priority pages, reducing ~280 lines of duplication
- Extract _ensureDefaultDocumentsOutputDir/_ensureDefaultAndroidMusicOutputDir in download queue provider
- Extract collectLibraryAudioFiles() and applyDefaultLibraryMetadata() in Go library_scan.go
- Extract plainTextLyricsLines() in Go lyrics.go, used by Apple Music, Musixmatch, and QQ Music clients
- Detect error JSON payloads from Apple Music and QQMusic proxies
- Add lyricsHasUsableText validation for usable lyrics content
- Skip empty word lines in synced lyrics parsing
