Phase 13 Plan 02: Library Filter UI & View Wiring Summary

Library filter dropdown in top bar with conditional ByLibrary queries across all browse views, detail views, and search — playlists remain unfiltered

Performance

• Duration: 9 min
• Started: 2026-03-16T13:32:45Z
• Completed: 2026-03-16T13:41:49Z
• Tasks: 1 (of 2 — Task 2 is human verification checkpoint)
• Files modified: 12

Accomplishments

• Created library-filter dropdown component that loads library list from backend and sets store filter
• Modified library-store to conditionally call ByLibrary or unfiltered queries based on selectedLibraryId
• Wired all browse views (tracks, albums, artists, genres) to automatically use filtered data
• Wired detail views (genre-details direct Wails call, artist-details via store, cover-grid album dropdown) to respect filter
• Updated album-selection helper for library-aware drag/context-menu file path resolution
• Verified playlists use separate PlaylistStore — not affected by library filter
• Verified search is client-side (rankTracks on loaded data) — inherits filter automatically

Task Commits

Each task was committed atomically:

1. Task 1: Add library filter state + dropdown + wire all views - 42b8cf9 (feat)

Task 2: checkpoint:human-verify (pending user verification)

Files Created/Modified

• frontend/src/components/library-filter/library-filter.ts - NEW: Library filter dropdown component
• frontend/src/store/library-store.ts - selectedLibraryId state, ByLibrary conditional calls, getLibraries()
• frontend/src/store/controllers/library-controller.ts - Pass-through for selectedLibraryId, setSelectedLibrary, getLibraries
• frontend/index.html - Added <library-filter> to top bar
• frontend/index.ts - Import library-filter component
• frontend/src/components/cover-grid/cover-grid.ts - GetAlbumTracksByLibrary in dropdown
• frontend/src/components/cover-grid/album-selection.ts - Library-aware fetchAlbumTracks helper
• frontend/src/components/artists-view/artists-view.ts - GetAlbumsByArtistByLibrary + GetAlbumTracksByLibrary
• frontend/src/components/genres-view/genres-view.ts - GetTracksByGenreByLibrary for context menu
• frontend/src/components/genre-details/genre-details.ts - GetTracksByGenreByLibrary for track loading
• frontend/wailsjs/go/library/Library.d.ts - Regenerated with ByLibrary bindings
• frontend/wailsjs/go/library/Library.js - Regenerated with ByLibrary bindings

Decisions Made

• Search is entirely client-side (rankTracks filters already-loaded tracks), so no backend SearchTracksByLibrary call needed — the library filter naturally scopes search results via the filtered track list
• Used native <select> element for dropdown rather than a custom Lit component — compact, accessible, matches search bar height
• Library filter resets on app restart (no localStorage persistence) per CONTEXT.md requirement
• getAlbumsByArtistNameCached returns null when library filter active to avoid stale cross-library data

Deviations from Plan

Auto-fixed Issues

1. [Rule 3 - Blocking] Wails bindings not yet generated for ByLibrary methods

• Found during: Task 1 (start)
• Issue: Plan 13-01 added Go methods but bindings weren't regenerated
• Fix: Ran wails generate module before implementation
• Files modified: frontend/wailsjs/go/library/Library.d.ts, Library.js
• Verification: All ByLibrary imports resolve correctly
• Committed in: 42b8cf9

2. [Rule 1 - Bug] Info type uses lowercase property names (id, name) not uppercase

• Found during: Task 1 (TypeScript typecheck)
• Issue: library-filter.ts used lib.ID and lib.Name but Wails-generated Info type uses lib.id and lib.name
• Fix: Changed to lowercase property access
• Files modified: frontend/src/components/library-filter/library-filter.ts
• Verification: tsc --noEmit passes cleanly
• Committed in: 42b8cf9

---

Total deviations: 2 auto-fixed (1 blocking, 1 bug) Impact on plan: Both fixes required for compilation. No scope creep.

Issues Encountered

None

User Setup Required

None - no external service configuration required.

Next Phase Readiness

• All automated implementation complete — awaiting human verification checkpoint (Task 2)
• After verification: Phase 13 complete, multi-library support fully delivered
• v1.1 milestone only needs final Phase 13 checkpoint approval
