Goal Achievement

Observable Truths (from ROADMAP Success Criteria)

#	Truth	Status	Evidence
1	The default track list shows tracks from all libraries merged — the user sees their complete collection as one unified view	✓ VERIFIED	library-store.ts:41 — `selectedLibraryIdValue: number
2	User can select a specific library from a filter control and all views (tracks, albums, artists, genres) show only that library's content	✓ VERIFIED	library-filter.ts (107 lines) — <select> dropdown in top bar with "All Libraries" default + per-library options. setSelectedLibrary() calls invalidate() which clears all caches + resets scroll positions + triggers eagerFetch(). Each store method dispatches to ByLibrary variant when selectedLibraryIdValue !== null. Detail views wire through: cover-grid.ts:980-987 (GetAlbumTracksByLibrary), genre-details.ts:183-193 (GetTracksByGenreByLibrary), genres-view.ts:737-743 (GetTracksByGenreByLibrary), artists-view.ts:939-952 (GetAlbumTracksByLibrary).
3	Search results respect the active library filter	✓ VERIFIED	Per SUMMARY key-decision: client-side rankTracks() operates on already-filtered track data from library store. When library filter is active, getTracks() returns library-scoped data, so search inherits the filter automatically without needing a separate SearchTracksByLibrary backend call. Backend SearchTracksByLibrary method exists (query.go:784-827, search.go:292-375) as a fallback capability.
4	Playlists can contain tracks from multiple libraries — adding tracks from different libraries to the same playlist works naturally	✓ VERIFIED	playlist-view/ and playlist-details/ have zero imports of selectedLibraryId or setSelectedLibrary. playlist-details imports libraryStore only for getCachedTracks() and getCachedAlbums() (cover art resolution in track-details dialog, L433-454). Playlist data flows from playlist.Service (Go) which is library-agnostic — no library_id filtering. playlist_tracks.sql schema has nullable audio_file_id with ON DELETE SET NULL for phantom support.
5	When a library is removed, its tracks in playlists become phantom entries — visually distinguished with preserved metadata instead of disappearing	✓ VERIFIED	Schema: playlist_tracks.sql:6-11 — phantom_title, phantom_artist, phantom_album, phantom_duration_ms, phantom_genre, phantom_cover_art_path columns. phantom_file_path column (L12, migration 7). Backend: crud.go:248 stores phantom_file_path on removal. playlist.go:1497-1504 — ResolvePhantomTracksAfterScan() method. app.go:176-178 — ScanHooks wiring. Frontend: playlist-details.ts has 41 phantom-related lines — .phantom CSS class, phantom-resolver component import, locate/remove actions.

Key Link Verification

From	To	Via	Status	Details
library-store.ts	@go/library/Library	Conditional GetAllTracksByLibrary/GetAllTracks call	✓ WIRED	L8-13 imports ByLibrary bindings; L133-136 dispatches based on selectedLibraryIdValue
library-filter.ts	library-store.ts	libraryCtrl.setSelectedLibrary()	✓ WIRED	L75 calls this.libraryCtrl.setSelectedLibrary(id) on change event; L80 reads this.libraryCtrl.selectedLibraryId

Human Verification Required

All automated checks pass. The following items require human testing for complete confidence:

1. Library Filter Visual Presentation

Test: Run app with wails dev -tags webkit2_41, verify dropdown appears in top bar between title and search bar Expected: Compact 32px dropdown with "All Libraries" default, design-token styling Why human: Visual appearance and positioning cannot be verified programmatically

2. Filter Responsiveness

Test: Select a specific library from the dropdown Expected: All views (tracks, albums, artists, genres) immediately refresh with only that library's content; loading skeleton shows briefly Why human: UI responsiveness, loading state timing, and data correctness require visual inspection

3. Phantom Track Display After Library Removal

Test: Add tracks from library A to a playlist, then remove library A Expected: Tracks become phantom entries (greyed out, warning icon), metadata preserved, locate/remove buttons visible Why human: Visual phantom styling and resolver behavior need interactive testing

4. Phantom Auto-Resolution After Re-Scan

Test: Remove library → re-add same library → scan → check playlists Expected: Previously phantom tracks automatically resolve back to real tracks Why human: End-to-end flow through ScanHooks callback and M3U8 path matching

5. Filter Reset on App Restart

Test: Select a library filter, restart the app Expected: Filter resets to "All Libraries" (no persistence) Why human: Requires app restart cycle

Note: Plan 13-02 included a human checkpoint (Task 2) that was marked APPROVED during execution. The SUMMARY documents comprehensive end-to-end verification was performed during development.

Gaps Summary

No gaps found. All 5 ROADMAP success criteria are satisfied. All 7 requirement IDs (VIEW-01 through VIEW-04, PLAY-01 through PLAY-03) have implementation evidence in the codebase:

• Backend: 7 ByLibrary SQL queries + 8 Go wrapper methods + 1 FTS search method + phantom resolution infrastructure
• Frontend: Library filter dropdown component (107 lines) + store with conditional ByLibrary dispatch + controller pass-through + wiring in all browse views and detail views
• Phantom tracks: Schema columns + phantom_file_path storage on removal + ScanHooks-based auto-resolution + existing phantom UI in playlist-details
• Playlists isolated: playlist-view and playlist-details have no library filter dependency — confirmed by grep showing zero selectedLibraryId/setSelectedLibrary references
• Scroll reset: invalidate() resets all scrollPositions to 0 on filter change
• No persistence: selectedLibraryIdValue defaults to null, no localStorage/backend persistence code

All commits verified in git history: 5cc58ce, 5f7de50, 42b8cf9, f05d2bb, 93262b9, 9f595b7.
