- Add SyncedFile message and subdir scoping to RescanOrigin proto
- Add label, album_type, cover_url fields to UpdateMetadataRequest/MetadataResponse
- Implement OriginScanner: walk, hash, diff, ingest with live FUSE tree and content fetcher registration
- Add enrichment DB columns: enrichment_source, enriched_at, enrichment_attempts, genres_json, label, album_type, cover_url
- Add EnrichmentUpdate struct and update_enrichment DB method
- Wire BatchUpdateMetadata to write enrichment fields alongside audio metadata
- Wire gRPC server into CLI mount command with --grpc-port flag
- Pass VirtualTree and ContentFetcher to scanner so rescanned files are immediately visible and readable via FUSE
The metadata overlay feature was implemented but not connected to the
CLI daemon. Files were being served with original metadata instead of
synthesized headers from the database.
- Import OverlayReader from musicfs-cache
- Create OverlayReader with db, format_registry, and reader
- Call .with_overlay() on MusicFs builder
Tested: ffprobe now shows modified metadata from database updates.
- Add MetadataService with 5 RPCs (Get, Update, Clear, Batch, Import)
- Add 11 message types for requests/responses
- Use optional fields and map for custom_tags
- Proto codegen successful, all tests pass
- Update read() to use OverlayReader when available
- Map OverlayError to libc error codes
- Maintain 30s timeout and backward compatibility
- Fallback to FileReader for non-overlay files
- All tests pass, full workspace compiles
- Add overlay_reader field to MusicFs struct
- Add with_overlay() builder method
- Update getattr() to call estimate_virtual_size()
- Graceful fallback to original size
- All tests pass, backward compatible
