The download-time ISRC index now also parses mp3, m4a, ogg, and opus
tags through the existing native readers instead of skipping everything
but .flac. Library settings gain a Review duplicates sheet that groups
history and local-library rows sharing an ISRC via SQL over the
attached databases (no filesystem walk, SAF-safe), shows quality
badges, and offers keep-best and per-copy delete with confirmation.
The index was rebuilt from scratch every 5 minutes even while
AddToISRCIndex kept it write-consistent after every download, and each
rebuild parsed the FULL metadata of every FLAC in the library —
including multi-megabyte embedded cover art — sequentially, with the
triggering download blocked behind the build lock. For a few thousand
files that is gigabytes of flash I/O per rebuild, repeated throughout
a long batch.
- Indexing now reads only the Vorbis comment block (block headers are
walked and picture/padding payloads seeked past, never loaded)
- A per-file (size, mtime) -> ISRC cache carries across rebuilds, so a
rebuild is normally a stat walk that re-reads only changed files
- Add() refreshes the index timestamp, so the TTL no longer forces a
rebuild in the middle of the workload the index exists to serve
- Cold builds parse with 4 workers, matching the library scanner
- 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
