Remove the never-called checkAvailability chain end to end (Dart bridge +
provider, Android/iOS MethodChannel handlers, Go exports) and stop restoring
its persistent lookup cache on every cold start; the legacy prefs key is
cleared on next cache reset.
Delete dead Go: romaji.go (test-only), the no-op pre-warm chain
(PreWarmTrackCache/PreWarmCache/…), retired Download stubs, and a batch of
exports with no Dart/Kotlin/Swift/Go caller. Kept GetTrackCacheSize/
ClearTrackIDCache (Settings cache screen), SetAllowedDownloadDirs and
Clear/GetItemProgress (live test seams).
Dedup: single updateFlacVorbis + replaceFlacPictures helper behind the six
FLAC tag writers; merge byte-identical extractCommentFrame/extractLyricsFrame
into extractLangTextFrame.
go build/vet + 237 go tests, flutter analyze + tests green.
Coordinated rename of the nine store-named bridge surfaces: Go
exports (InitExtensionStoreJSON -> InitExtensionRepoJSON etc.),
method-channel strings, the Kotlin and Swift handlers, and the Dart
PlatformBridge methods. Channel strings verified 1:1 across
Dart/Kotlin/Swift; gomobile bindings match the new export names.
Android MediaStore APIs untouched. store_registry_url pref key kept
for existing users. Local Android/iOS builds need the gobackend
AAR/xcframework rebuilt; CI does this in the release workflow.
extension_store.go -> extension_repo.go, exports_store.go ->
exports_repo.go; unexported types/functions/log tag renamed to match
the user-facing repo terminology. The gomobile-exported function
names (InitExtensionStoreJSON etc.) are the bridge ABI called from
Kotlin/Swift and stay unchanged, as does the store_registry_url pref
key that guards existing users' settings.
Detect .sflx and .spotiflac-ext from the registry download URL when saving
repo downloads, and extract findExtension so the destination path can use
the correct package extension.
Classify verification-required and rate-limit errors from extensions, propagate Retry-After seconds through the download fallback, report session-grant success/failure, and add a completeGrant action fallback in the runtime.
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.
All search, metadata, and download providers are now exclusively
supplied by extensions. The built-in provider registry that previously
exposed Deezer/Tidal/Qobuz as hardcoded providers is fully removed.
Removed across Go, Dart, Kotlin, and Swift:
- BuiltInProviderSpec class, registry, and all accessor helpers
- SearchProviderAllJSON, GetBuiltInProvidersJSON, ParseProviderURLJSON,
ParseDeezerURLExport Go exports and their platform channel bindings
- Built-in provider items in search dropdown, service picker, and
provider priority UI lists
- provider_ui_utils.dart helper file
Deezer metadata enrichment (ISRC lookup, extended metadata, cover
upgrade) remains fully functional through direct DeezerClient calls
in the download pipeline — these are not part of the provider
registry and are unaffected.
Mark deezer as a retired built-in metadata provider so stale user
priority lists are cleaned up on next launch.
- Add 16 Go supplement test files covering extension runtime, providers,
health checks, lyrics, metadata, HTTP utils, library scan, and more
- Add Dart model/utils test suite (test/models_and_utils_test.dart)
- Update settings.g.dart with deduplicateDownloads serialization
