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.

FullRescan scans the first library directly, then queues the rest.
The PostScan hook was restarting the index build after the FIRST
library, which starved the queued libraries for DB access — they
never scanned, leaving the library with only 6 tracks.
Fix: move StartIndexBuild to the OnAllScansComplete hook, which
fires when drainQueue finds no more libraries to scan. This ensures
ALL libraries finish scanning before the index build starts.
For startup soft scans: if no scans were queued (library unchanged),
start the index build directly. If scans WERE queued, the hook
handles it.
Added OnAllScansComplete callback to ScanHooks. Called from
drainQueue when the scan pipeline goes idle.
updateMBIDs was calling l.db.ExecContext (main connection) while
inside a transaction that held the write lock. With SQLite's
SetMaxOpenConns(1), this deadlocked — the UPDATE waited for the
transaction to release the lock, but the transaction waited for
the UPDATE to complete.
Fix: pass *sql.Tx through processMetadata to updateMBIDs and use
tx.ExecContext instead. All MBID writes now happen within the same
transaction as the entity upserts.
Migration 13 adds nullable mbid TEXT columns to artists,
release_groups, and recordings with partial indexes.
Metadata extraction (tags.go) now reads MusicBrainz IDs from Raw()
tags — handles both Vorbis (musicbrainz_artistid) and ID3v2
(MusicBrainz Artist Id) key formats.
Scan pipeline (library.go) updates MBIDs after entity upsert via
raw SQL UPDATE. Only sets mbid if currently NULL (preserves existing
values on rescan).
LibraryMBIDIndex (librarymbid.go) provides:
- CheckMBIDs: batch lookup for 'In Library' badges
- GetArtistMBID: single artist name→MBID lookup
- AllArtistMBIDs: full dump for search index Tier 3
MBIDs will be populated on next library rescan. Existing files
need a rescan to backfill.
- 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
- Add phantom_file_path column to playlist_tracks (migration 7)
- Store original file_path during RemoveLibrary phantom metadata population
- After each successful scan, UPDATE phantom tracks whose phantom_file_path
now matches an audio_files row, re-linking them and clearing phantom metadata
- Update schema file, sqlc generated code, and database test for new column
Files that fail to save (e.g. UNIQUE constraint from pre-existing
tracks with a different library_id) were not counted in any progress
counter, leaving the progress bar stuck at 0%. Now increments skipped
so processed = added + skipped + updated reflects all files visited.
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

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

- Regenerate Wails TypeScript bindings for new config methods
- Fix wsl lint in library.go (blank line before logger call)
- Add scanActive, scanCancel, scanPaused, scanPauseCh fields to Library struct
- Create scan_control.go with CancelScan, PauseScan, ResumeScan, IsScanActive, IsScanPaused
- Thread per-scan scanCtx through walk and worker pipeline

- Fix errcheck for db.Close() in testhelper.go
- Fix errcheck, nlreturn, wsl, gofumpt issues in genevents/main.go
- Fix gofumpt and wsl issues in library.go
Add live progress reporting during library scans:
- Pre-walk count: fast WalkDir to count audio files upfront for
percentage calculation (~1-2s overhead)
- Progress ticker: emits ScanProgress events every 300ms with
phase, file counts (added/skipped/updated), and total
- Phase labels: counting → scanning → thumbnails → orphans
- Frontend: progress bar with percentage, file counts breakdown,
and phase indicator in both config-page and library-manager
Replaces the static 'Scanning...' text with a live progress bar
showing e.g. '62% — Scanning... 1,247 / 2,013 files (891 new,
356 skipped)'
The search_index is a contentless FTS5 table (content=''), which
SQLite does not support DELETE on. ClearSearchIndex now drops and
recreates the virtual table. Single-row DeleteSearchIndex becomes
a no-op since contentless FTS5 also cannot delete individual rows;
stale entries are harmless (search JOINs filter them out) and the
index is fully rebuilt during FullRescan.
- Migration 5 rebuilds release_groups with UNIQUE(name, album_artist_credit_id)
- Drops and recreates track_metadata VIEW during table rebuild
- Temporarily disables FK checks for safe table rebuild
- Entity cache now keys by album name + artist credit ID
- Update tests to use composite cache keys
- 7 SAFETY comments in search.go (FTS5 MATCH/INSERT/DELETE operations)
- 3 SAFETY comments in library.go (FTS5 INSERT/DELETE in commitNewAudioFile, updateAudioFileMetadata)
- 1 SAFETY comment in rescan.go (FTS5 DELETE in clearAllLibraryData)
- 1 SAFETY comment in persistence.go (variable-count multi-row INSERT)
- Cross-references link library.go/rescan.go back to search.go
- Two-part format: why sqlc can't handle it + what makes it safe
- Add ScanWarning struct with FilePath/Phase/Err to ScanMetrics
- Add mutex-protected addWarning method for concurrent use
- Reclassify walk, extraction, commit, orphan, variant, FTS failures as warnings
- Update commitBatch to return only fatal tx.Commit errors
- Update cachedLinkArtist to check errors via database.IsUniqueViolation
- Update handleConfigUpdate to capture and log scan warning count
- Queue.SetContext acquires existing q.mu before writing q.ctx
- Library struct gets new mu sync.Mutex; SetContext and SetRescanHooks acquire it
- Playlist Service struct gets new mu sync.Mutex; SetContext and SetFavoritesConfig acquire it
- Library and Playlist release lock before calling post-init methods (registerEventHandlers, migrateExistingPlaylists)
album artist gets populated with artist as fallback (frontend also uses
this as display name fallback for albums). added scroll position
persistence when switching main views. also added frontend cache for
faster switching.
- Fix 10 err113 violations: extract dynamic errors to package-level sentinels
- Fix 12 errcheck violations: handle unchecked error returns in player,
metadata, and config packages
- Fix 4 revive stutter warnings: rename player.PlayerState to player.State,
player.PlayerVolume to player.Volume, queue.QueueTrack to queue.Track,
queue.QueueState to queue.State
- Fix 2 staticcheck SA4001: simplify *&x to x in assets handler
