- Add container table with Master (iPod) and Music containers
- Add version_info, db_info, genre_map, location_kind_map, category_map
- Create Dynamic.itdb, Extras.itdb, Genius.itdb with minimal schemas
- Insert default container entries with correct PIDs
- Nano 7G firmware requires all these for music display
- copy_track_to_ipod: create target directory via os.makedirs
- sync_itunescdb: create iTunesCDB from scratch if missing
- sync_itunescdb: create iTunesCDB.ext with hash if missing
- Creates all required tables (item, artist, album, avformat_info,
store_info, item_to_container, track_size_calc) in Library.itdb
- Creates location table in Locations.itdb
- Called from Nano7Database.__init__(), so empty DB is always valid
- Fixes 'no such table: item' error on iPod with wiped DB
- New src/artwork/ module with iPod Nano 7G cover art support
- codecs: RGB565/RGB555/UYVY/JPEG encode/decode via numpy
- presets: 50+ iPod artwork format definitions
- chunks: ArtworkDB binary parser/writer (MHFD→MHSD→MHLI→MHII→MHNI)
- writer: ithmb file generation + ArtworkDB assembly
- extractor: cover extraction from audio files (APIC/covr/FLAC pictures)
- cache: local JPEG cache for player UI
- iTunes-style playback bar with 60x60 cover art display
- Scan library now caches cover art by artist+album
- iPod Nano7 transfer writes artwork to ArtworkDB + ithmb
- FFmpeg conversion preserves embedded cover art (-map 0:t?)
- One-time reembed_covers.py script in /tmp
- MetadataHandler process_file() fallback to cover_path
- Bug fixes: missing read_existing_artwork import, signed PID in Q format
- Fix avformat_info duration: store in SAMPLES not ms (firmware uses this to
determine playback length; wrong units caused tracks to stop at ~3-11 seconds)
- Add Locations.itdb insert/delete for each track (ipod_path mapping)
- Add sync_locations_cbk() with HASHAB signing via WASM module
- Detect FirewireGuid from SysInfo for cbk header signature
- Add duplicate detection in add_track (title+artist match, skip if exists)
- Add get_orphaned_files() and delete_orphaned_files() for cleanup
- Sync cbk after every add/delete operation
- Add get_all_tracks() to load all tracks with file paths via tag matching
- Add delete_track() to remove tracks from SQLite DB and delete physical files
- Add _cleanup_orphaned_entries() to remove orphaned artist/album records
- Add track count label and 'Remove Selected' button to Transfer tab
- Load existing tracks on device detection
- Confirmation dialog before deleting tracks
- Reload track list after successful transfer
- Add extract_tags() to metadata_handler.py: reads tags from FLAC, MP3, OGG, M4A
- Support ID3v2 (MP3), Vorbis comments (FLAC/OGG), MP4 tags (M4A)
- Extract cover art from METADATA_BLOCK_PICTURE (FLAC), APIC (MP3), covr (M4A)
- Update _run_convert to use extract_tags instead of guessing from filename
- Fix tag reading in ipod_nano7_db.get_audio_info() using EasyID3 for MP3
- Create ipod_nano7_db.py module for Nano 7 SQLite DB management (Library.itdb)
- Fix case-insensitive iPod label detection in device detection
- Add /run/media to mount point search paths for Arch Linux
- Support already-mounted devices without requiring ifuse
- Add local file selection in Convert tab (FLAC, WAV, OGG, etc.)
- Transfer now properly registers tracks in iPod database so they appear in UI
