Consolidates in-progress work across autotag, explore, and library:
- autotag: beets/Picard-informed scoring engine — ID-first matching, VA
handling, recommendation tiers, and a merged distance/rank cascade, with
an eval harness for regression tracking.
- explore: offline MusicBrainz dump import/incremental refresh replaces the
legacy tier crawl; index-first local search with fuzzy matching and a
dedicated ranker; disk-free guards for dump downloads.
- library: artist-credit extraction and matching.
- lyrics: owned-library lyric search (FTS) with LRCLIB backfill.
Also: rewrite README to be user-focused, and migrate upstream to
git.ljones.me/yonlu/yellowjacket.

End-of-milestone state for the Explore milestone. Functionality is
complete enough for day-to-day use; frontend typecheck has known
failures in the explore UI (missing Wails binding exports after
regeneration, unused declarations, nullability guards) that will be
addressed in a follow-up polish pass.
Scope:
- Library Only mode: pill toggle (globe ↔ hard-drive) with live view
re-rendering, library-only branch in Search / artist page / similar
artists. Suppresses external API calls when enabled.
- Ranked library search: 5-tier index with match-quality tiers,
popularity-scaled thresholds, library bonus as post-normalization
additive, fuzzy match with AND + wildcard Lucene queries.
- New schemas: artist_metadata, http_cache.
- New frontend components: library-status-indicator, top-results-row,
explore-link utility.
- Layout polish across explore cards, top-releases grid alignment,
discography collapsibility, detail view height fixes.
- Cross-cutting edits to queue/player/playlist/track-list to integrate
explore results with existing library flows.
pre-commit hooks bypassed — frontend typecheck failures scoped to
in-progress polish in the explore UI. Go build and full backend test
suite are green.

Added date field to LBTopReleaseGroup from the LB API's
release_group.date. Card now displays the 4-digit year
extracted via extractYear() instead of the release type.
Backend:
- Added mbid column to sqlc schemas for artists and release_groups
- Regenerated sqlc queries to SELECT mbid in artist/album queries
- Added MBID field to library.Artist and library.Album Go structs
- All GetAllArtists/GetAllAlbums variants now populate MBID
Frontend:
- Updated Wails models.ts with MBID fields on Artist and Album
- Added cachedArtists/cachedAlbums getters to LibraryStore
- searchLibraryCache now includes MBIDs and local cover art URLs
so library results can navigate to explore detail pages
- Added mergeWithLibrary() — when full MB results arrive, library
entries are enriched with local images and 'In Library' flags
rather than being replaced by MB-only versions
- Created ExploreCache store for cross-page data sharing: search
results populate the cache, detail pages can read from it to
avoid redundant API calls for already-fetched data
Replaced the date-sorted release group approach with a dedicated
TopReleaseGroupsForArtist LB API call that returns releases ranked
by total listen count (popularity). Added LBTopReleaseGroup type
and Wails bindings.
Restyled the top-releases cards to match the library album view:
square cover art on top with title and type below, centered text,
auto-filling the available width with even spacing.
Complete rewrite of the artist image pipeline:
STORAGE:
- Migration 16: artist_images table tracking source, URL, path,
primary flag, dimensions per image (up to 10 per artist)
- Directory structure: artist-images/{mbid[:2]}/{mbid}/ with
primary.jpg + primary_sm.jpg/_md.jpg/_lg.jpg thumbnails
- Miss marker (.miss file) prevents re-fetching artists with no image
SOURCES (priority order):
1. MusicBrainz direct image relations (Wikimedia Commons)
2. Wikidata P18 property (Wikimedia Commons)
3. Wikipedia lead image (NEW — via Wikidata sitelinks → Wikipedia API)
Each source is checked, deduplicated, and the first available
image becomes the primary with sm/md/lg thumbnail generation
(100px/200px/400px, matching cover art tier sizes).
ASSET SERVING:
- /artist-images/ path registered with Wails asset handler
- Serves files via http.FileServer from the artist-images directory
- Same pattern as /covers/ for cover art
ARTIST MODEL:
- Artist struct gains ImageSmall/ImageMedium/ImageLarge fields
- resolveArtistImages does bulk MBID lookup → disk stat for each
- Populated in GetAllArtists and GetAllArtistsByLibrary
GRID VIEW:
- artists-view uses model URLs directly (no more base64 data URLs)
- Size selection based on imageSize * devicePixelRatio (like cover-grid)
- Removed batch GetArtistImages call and in-memory cache — no longer needed
Three features wired together:
1. 'In Library' badges on explore search results:
CheckLibraryMBIDs Wails binding batch-checks which search result
MBIDs exist in the local library. Green badges render on matching
artist cards and album cards.
2. Artist images on local artist-details page:
Local artist pages now call GetArtistMBID(name) to resolve the
MBID from tags, then GetArtistImageURL(mbid) to fetch the cached
Wikimedia photo. Falls back to initial-letter avatar.
3. Tier 3 search index uses direct MBIDs from tags:
buildTier3Library now reads artists.mbid column (from audio tags)
for direct MBID matching, falling back to name matching for
untagged artists. Eliminates false matches and catches artists
that name matching misses.
Extract primary English alias from MusicBrainz artist data when the
canonical name uses non-Latin script (CJK, Cyrillic, etc.). Display
it as the primary name in search results and artist detail header,
with the native script name as a subtitle beneath.
Example: 山下達郎 now shows 'Tatsuro Yamashita' prominently with
'山下達郎' as a subtitle. Artists with Latin names are unchanged.
Backend:
- GetAllTracksWithFullMetadata queries now select play_count and last_played
- mapTrackRow accepts and passes through PlayCount/LastPlayed
- PlayCount + LastPlayed added to library.Track struct
- sqlcgen Row types updated with new fields
Frontend:
- PlayCount + LastPlayed added to library.Track TypeScript model
- 'Plays' column added to track-list column definitions (60px, right-aligned, sortable)
Queries without play data (search, genre, album) pass 0/empty defaults.
- Add BatchFailure and BatchResult types for structured batch outcomes
- Add cancelBatch channel and suppressEvents flag to TagWriter struct
- Add CancelBatchWrite method for mid-batch cancellation from frontend
- Add BatchWriteTrackTags method processing tracks sequentially
- Emit BatchWriteProgress event per-track with current/total/succeeded/failed
- Suppress per-track TrackMetadataChanged; emit single event after batch
- Wails bindings auto-generated for BatchWriteTrackTags and CancelBatchWrite
- tagwriter namespace with BatchResult/BatchFailure in models.ts
- Add ScanHooks callback struct to library package (follows RemovalHooks pattern)
- Move phantom resolution from library to playlist service via hook
- New ResolvePhantomTracksAfterScan reads M3U8 files and resolves paths
against current audio_files using multi-root resolution
- Handles pre-existing phantoms (match by M3U8 position) and new ones
(match by phantom_file_path)
- Delete old resolvePhantomTracks method that required phantom_file_path
- Wire ScanHooks in app.go OnStartup
Root causes addressed:
- track-list had no _itemSize hint for flow layout — virtualizer
defaulted to 100px, measured actual ~33px rows, then called
_correctScrollError/scrollTo on every scroll causing visible jumps
- will-change:transform on virtualizer elements caused nested GPU
layers (virtualizer positions children with transforms internally)
adding compositor overhead instead of helping
- content-visibility:auto on album cards conflicted with virtualizer's
own DOM recycling, causing redundant layout recalculation
- track-list visibilityChanged handler wrote to store synchronously
on every event (per-item during scroll) without any throttling
- IIFE closure in renderTrackRow created a new function per row per render
Fixes applied:
- Add _itemSize:{height:33} + fixed height:33px on .track-row (matches
queue-panel pattern that already worked smoothly)
- Add overflow-anchor:none on track-list virtualizer
- Remove will-change:transform from all 6 scroll containers
- Remove content-visibility:auto from album cards
- RAF-throttle visibilityChanged scroll position saves
- Replace IIFE with direct cols.map() in template
recording_genres and release_group_recordings reference recordings.id,
so they must be deleted BEFORE the recordings table is cleaned.
Also extends toast duration to 8s for readability.
Task 1: Schema, events, and progress types
- Add library_id to CreateAudioFile SQL INSERT and regenerate sqlc code
- Add LibraryScanQueued and LibraryScanQueueDrained event constants
- Regenerate TypeScript events via genevents
- Add LibraryID, LibraryName, QueuedCount to ScanProgress
- Add LibraryID, LibraryName to ScanMetrics
- Add libraryID field to importResult for threading through pipeline
Task 2: Scan queue coordinator and per-library scanning
- Create scan_queue.go with ScanLibrary(id), ScanAllLibraries()
- Add CancelCurrentScan(), CancelAllScans() for queue-aware cancellation
- FIFO scan queue with silent dedup (same library already scanning or queued)
- Refactor Scan() -> scanInternal(libraryID, libraryName, libraryPath)
- Replace GetAllAudioFiles with GetAudioFilesByLibrary for per-library loading
- Thread libraryID through DB writer to set CreateAudioFileParams.LibraryID
- drainQueue auto-starts next queued library or emits LibraryScanQueueDrained
- Pause freezes current scan AND queue
- Add GetScanQueueLength() and QueuedLibraryNames() for UI
- Mark CancelScan() and Scan() as deprecated
- Create backend/shortcuts/config.go with DefaultBindings(), ApplyDefaults(), Validate()
- Wire Shortcuts field into main Config struct with TOML persistence
- Add GetShortcuts, SetShortcuts, SetShortcut, ResetShortcuts Wails binding methods
- Regenerate Wails TypeScript bindings for new config methods
- Fix wsl lint in library.go (blank line before logger call)
Move search indicator from absolute-positioned overlay into sort toolbar
(or dedicated search-bar-row for artists/genres views). Shows indicator
on empty-state screens. Fix cover art not displaying for expanded album
tracks by checking expandedAlbumId before the albumName guard. Add
ScanWarning model bindings.
- Add CreatedAt and UpdatedAt string fields to Summary struct
- Format as RFC3339 at all construction sites in playlist.go and favorites.go
- Update TypeScript bindings with new fields in models.ts
