- All components import designTokens and include in static styles
- Hoist searchCtrl.term lookup outside per-column loop in renderTrackRow
- Search highlighting already short-circuits when search term is empty
- Import classMap in queue-panel.ts
- Replace array filter/join class construction with classMap in renderTrackItem
- Eliminates per-row array allocation in queue panel render hot path
- Import classMap from lit/directives/class-map.js
- Replace array filter/join class construction with classMap for track-row
- Convert fav-icon conditional class to classMap
- Convert cell alignment classes to classMap
- Eliminates per-row array allocation and string join in render hot path
- cover-grid: all 3 virtualizers (single, before-split, after-split) use repeat() with album.ID key
- artists-view uses repeat() with artist.ID key
- genres-view uses repeat() with genre.name key
- Removed gridKeyFunction (now inlined in repeat calls)
- Removed .renderItem and .keyFunction properties from all virtualizers
- New tokens.css.ts exports designTokens with --yj-icon-sm/md/lg and --yj-text-xs/sm/md/lg/xl
- Values derived from existing pixel sizes scattered across codebase
- :host scoped for component-level adoption via static styles array
- Library store notify() coalesces multiple calls per microtask tick into one subscriber notification
- Search input debounces store propagation by 150ms while keeping instant visual feedback
- Empty search input clears immediately for responsive UX
- Add phase1Meta parameter to resolveRemainingTracks
- Filter out already-resolved paths before lookupTrackMetaBatch call
- Merge Phase 1 results into Phase 2 lookup map
- Pass batchMeta from SetQueue call site to resolveRemainingTracks
- For 1000-track queue with Phase 1 resolving 50, Phase 2 now queries 950 instead of 1000
- Add persistAddTrack/persistAddTracks for O(1) append operations
- Add persistInsertTracks with variable-N position shift for insert-at operations
- Add persistRemoveTrack with single DELETE + position shift
- Wire AddTrack/AddTracks to use incremental INSERT (no full table rewrite)
- Wire InsertNext/InsertNextTracks/InsertTracksAt to use position shift + INSERT
- Wire RemoveTrack to use single DELETE + shift (no full table rewrite)
- RemoveTracks keeps full persistTracks rewrite (bulk operation per design)
- Preserve shuffle order regeneration in all mutation paths
- Remove eagerFetch() call from LibraryStore constructor
- Add deferEagerFetch() that waits for DOMContentLoaded event
- App shell renders before backend data roundtrips begin
- All 4 data types (tracks, albums, artists, genres) still loaded eagerly
- invalidate() still calls eagerFetch() directly for post-scan refresh
- 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 LookupTrackMetaByPaths sqlc query using track_metadata VIEW with sqlc.slice()
- Replace hand-crafted fmt.Sprintf IN clause in lookupChunk with sqlc-generated call
- Preserve lookupTrackMetaBatch chunking at maxSQLiteVars (900)
- All queue tests pass with -race
- Add backend/events/cmd/genevents/main.go using go/ast for deterministic output
- Add //go:generate directive to backend/events/events.go
- Generate frontend/src/events.ts with all 21 constants including LibraryConfigChanged
- Atomic file writes via temp file + rename
- Comment groups preserved with trailing period stripping
- TestCachedUpsertArtistCredit: cache hit returns same ID on second call
- TestCachedLinkArtist: skips duplicate INSERT via linkedCredits cache
- TestCachedLinkArtist_MultiCredit: same artist linked to different credits
- TestCachedUpsertGenre: genre cache returns same ID on repeated calls
- TestResolveReleaseGroup: creates release group, updates cover art on cache hit
- TestResolveReleaseGroup_CacheHit: pre-populated cache returns cached ID
- TestOrphanDeletion: DeleteAudioFile removes row, documents contentless FTS5 limitation
- TestEntityCache_EmptyFields: empty artist name, empty album, AlbumArtist reuse
- TestGetRecordingName: title present, fallback to filename sans extension
- TestToNullInt64: zero as null, positive/negative as valid
- TestToNullString: empty as null, non-empty as valid
- TestSplitGenres: empty/single/multiple genre splitting on || delimiter
- TestMapTrackRow: all 16 columns including string TrackLength, NullInt64 fields
- ToVolume/ToUserVolume at all boundary values (0, 25, 50, 75, 100)
- Out-of-range behavior for both conversion directions
- Full roundtrip characterization (0-100) with ±1 tolerance
- clampVolume at and beyond both boundaries
- stateToMediaControls for all states including unknown fallback
- Full roundtrip: SaveState/RestoreState preserves all fields (tracks, index, shuffle, repeat, shuffleOrder)
- Edge cases: empty queue, single track, no prior save state
- Track order: 10-track order preservation verification
- Overwrite: second SaveState replaces first
- 6 tests all passing with -race
