- Add fast-path SAF metadata reading via /proc/self/fd with displayNameHint support, falling back to temp copy
- Replace repeated findFile() CUE audio sibling lookups with cached case-insensitive directory listing
- Cache parsed CUE sheets to avoid redundant parsing during library scans
- Optimize incremental scan CUE modTime lookup from O(N*M) to O(N+M)
- Defer local library provider loading until localLibraryEnabled setting is true
- Replace O(n) track+artist history lookup with O(1) map-based lookup
- Delay startup maintenance tasks by 2s to reduce launch-time contention
- Replace batch Share action with batch Re-enrich in local album selection bar
- Full native/FFmpeg re-enrich flow with SAF write-back support
- Triggers incremental local library scan after completion to refresh metadata
- Queue tab: switch first selection action to Re-enrich when all selected items are local-only
- Refactor SAF FD handoff in MainActivity: drop detachFd/dup pattern, pass procfs
path to Go and let Go re-open it to avoid fdsan double-close race conditions
- Handle /proc/self/fd/ path in output_fd.go: re-open via O_WRONLY|O_TRUNC instead
of taking raw FD ownership
- Fix Ogg duration/bitrate calculation in audio_metadata.go:
- Use float64 arithmetic and math.Round for accurate duration
- Compute bitrate from file size / float duration at the source
- Validate Ogg page header fields (version, headerType, segment table) to avoid
false positives from payload bytes during backward scan
- Guard against corrupted granule values (>24h duration, <8kbps bitrate)
- Rename trackReEnrich label from 'Re-enrich Metadata' to 'Re-enrich' across all
13 locales and ARB files
- Update CHANGELOG.md with 3.7.0 entry
- Add Genre/Label/Copyright fields to DownloadResult struct
- buildDownloadSuccessResponse now prefers service result metadata over request
- enrichRequestExtendedMetadata fetches Deezer metadata by ISRC before download
- Flutter sends copyright in download request payload
- History merge preserves existing genre/label/copyright on re-download
- Accurate MP3 duration via Xing/VBRI VBR headers, MPEG2/2.5 bitrate tables
- Accurate Opus/Vorbis duration via last Ogg page granule position
- Bitrate field added to LibraryScanResult, LocalLibraryItem, DB v4 migration
- Lossy formats display format+bitrate instead of fake 16-bit quality
- Local library file date uses fileModTime instead of scannedAt
- SAF URI recovery for transient FD paths after download
- Improved SAF repair and download history path matching in library scan
- Extract quality probe logic into reusable enrichResultQualityFromFile
- Cover preview enlarged from 120x120 to 160x160 with shadow and better styling
- Layout changed from Wrap to Row with Expanded for side-by-side covers
- Label moved below image with labelMedium typography
- Cover editor section moved to top of edit form
- Added embedded cover preview cache with LRU eviction in metadata screen
- Added current cover extraction and preview in edit metadata sheet
- Added metadata sync to download history after edits
- Added embedded cover extraction cache in queue tab for downloaded items
- Added SAF mod-time tracking for cover refresh after metadata changes
- Add local library albums as clickable cards in Albums filter
- Merge downloaded and local albums into single unified grid (fix layout gaps)
- Create LocalAlbumScreen for viewing local album details with:
- Cover art display with dominant color extraction
- Album info card with Local badge and quality info
- Track list with disc grouping support
- Selection mode with delete functionality
- UI consistent with DownloadedAlbumScreen (Card + ListTile layout)
- Add singles filter support for local library singles
- Add extractDominantColorFromFile to PaletteService
- Add delete(id) method to LibraryDatabase
- Add removeItem(id) method to LocalLibraryNotifier
- Update CHANGELOG.md for v3.4.0
