Preserve romanization and translation metadata through Rust exports and cache, match rounded line times, and retain word endings. Highlight romanization with the main lyric clock in Material and Mornye.
Clear selection overlay ownership safely when collection screens are disposed. Add parser, rendering, cache and overlay lifecycle regression coverage.
Replace the Go backend with the Rust workspace and route Android/iOS through
UniFFI bindings. Include the migrated extension runtime, network, providers,
media metadata, downloads and library operations, with version 5.0.0+147.
Remove Go sources, adapters, native build selection and CI dependencies.
Build Rust unconditionally and lock the iOS Rust pod using a relative path.
Retain legacy source and migration evidence in a local ignored archive.
Validation: Android Kotlin compile and 53 native tests; Swift Rust-branch
equivalence and syntax; CocoaPods install; workflow, shell, Ruby, plist and
diff checks. Reuse the preceding 100 Rust tests, fmt/Clippy and five-ABI
build checkpoint; no new APK or iOS application build for this cleanup.
Known follow-up: URL/URLSearchParams globals are missing from the Rust JS
runtime. A controlled extension replay confirms a URL-resolution regression;
this commit does not fix that runtime gap.
Trim after removing inline timestamps before matching speaker prefixes in Dart. Run one 21-case usability corpus through Dart, Go, and Kotlin tests.
Document the shared fixture and trigger Dart and Go CI when its resources change.
Add FFmpegService.embedMetadataToM4a() for writing tags and cover art
into M4A files via FFmpeg. Fix two bugs in the same function:
- Remove '-disposition:v:0 attached_pic' which is only valid for
Matroska/WebM containers and causes FFmpeg to error on MP4/M4A
- Apply same fix to _convertToAlac which had the identical issue
Add M4A handling (isM4A branch) to all four embed call-sites:
track_metadata_screen (lyrics embed, re-enrich, edit metadata sheet,
format conversion), queue_tab, local_album_screen, and
downloaded_album_screen.
Add 'LYRICS'/'UNSYNCEDLYRICS' to _mapMetadataForTagEmbed so existing
lyrics survive a re-enrich cycle on M4A/MP3/Opus files.
Preserve existing lyrics before overwriting tags in the edit metadata
sheet (best-effort readFileMetadata before FFmpeg pass).
Extract mergePlatformMetadataForTagEmbed() into lyrics_metadata_helper
to deduplicate the identical metadata-mapping loops that existed in
queue_tab, local_album_screen, downloaded_album_screen, and
track_metadata_screen.
Wire ensureLyricsMetadataForConversion into the format conversion path
in track_metadata_screen so lyrics are carried through conversions.
Add ISRC and LABEL/ORGANIZATION mappings to _convertToM4aTags.
