Observable Truths
Plan 01 Truths
| # | Truth | Status | Evidence |
|---|---|---|---|
| 1 | Fresh database creates libraries table with name, path, created_at columns | ✓ VERIFIED | _libraries.sql contains CREATE TABLE IF NOT EXISTS libraries with all 3 columns + id PK |
| 2 | Fresh database creates audio_files with library_id FK column | ✓ VERIFIED | audio_files.sql line 13: library_id int NOT NULL DEFAULT 0, line 16: FOREIGN KEY(library_id) REFERENCES libraries(id), index at line 22-23 |

| 4 | Fresh database creates track_metadata VIEW including library_id | ✓ VERIFIED | track_metadata_view.sql line 26: af.library_id in SELECT |
| 5 | Existing v5 database is migrated to v6 atomically — backup created first, all changes in transaction | ✓ VERIFIED | database.go lines 718-1031: migration6MultiLibrary() — backup at line 728, FK OFF/ON wrapping, all 14 steps in order, PRAGMA user_version = 6 at line 1021 |
| 6 | Existing audio_files rows get library_id pointing to the auto-created default library | ✓ VERIFIED | database.go lines 794-806: ALTER TABLE audio_files ADD COLUMN library_id INTEGER NOT NULL DEFAULT %d with dynamic defaultLibID |
| 7 | Migration reads TOML DirectoryPath to create the default library row | ✓ VERIFIED | database.go line 736: readLibraryDirFromTOML(logger), lines 1035-1077: full TOML decode with Library.DirectoryPath; line 769: filepath.Base(existingDir) for library name |
Plan 02 Truths
| # | Truth | Status | Evidence |
|---|---|---|---|
| 8 | sqlc-generated queries exist for library CRUD (create, get, list, delete) | ✓ VERIFIED | libraries.sql has 7 queries (CreateLibrary, GetLibrary, GetLibraryByPath, GetAllLibraries, UpdateLibraryName, DeleteLibrary, CountLibraries); libraries.sql.go has generated Go functions for all 7 |
| 9 | Playlist track queries handle nullable audio_file_id and phantom columns | ✓ VERIFIED | playlists.sql: AddPlaylistTrack has 9 params including phantom columns; GetPlaylistTracksWithMetadata uses LEFT JOIN + COALESCE fallback chain + is_phantom computed column |

| 13 | Migration tests verify TOML config is read and default library created | ✓ VERIFIED | TestMigration6LibraryQueries tests full CRUD lifecycle; in-memory DBs skip TOML read (correct for test env — TOML read path verified by code inspection: readLibraryDirFromTOML returns "" for missing config) |
| 14 | Test helper NewTestDB creates v6 schema including libraries table | ✓ VERIFIED | testhelper.go line 60: runMigrations(ctx, db, slog.Default(), ":memory:"), line 66-71: sentinel library at id=0; NewTestDBWithLibrary helper at lines 87-107 |

Key Link Verification
Plan 01 Key Links
| From | To | Via | Status | Details |
|---|---|---|---|---|
database.go |
_libraries.sql |
embedded SQL schema execution in NewDB | ✓ WIRED | schemas.ReadDir("sql/schemas") at line 68 iterates all .sql files; _libraries.sql sorts before audio_files.sql alphabetically (_ < a), ensuring FK order |
database.go migration6 |
TOML config file | system.GetUserConfigDirPath + toml decode |
✓ WIRED | readLibraryDirFromTOML() at line 736 calls system.GetUserConfigDirPath(), reads config.toml, uses toml.Decode with Library.DirectoryPath struct |
Plan 02 Key Links
| From | To | Via | Status | Details |
|---|---|---|---|---|
queries/libraries.sql |
schemas/_libraries.sql |
sqlc schema awareness | ✓ WIRED | sqlc.yaml configures schema dir as ./sql/schemas — generated code in libraries.sql.go proves sqlc successfully processes both schema and queries |
database_test.go |
database.go migration6 |
NewTestDB runs all migrations | ✓ WIRED | testhelper.go line 60: runMigrations(ctx, db, slog.Default(), ":memory:") — all 5 migration 6 tests pass confirming migration executes correctly |
Requirements Coverage
| Requirement | Source Plan | Description | Status | Evidence |
|---|---|---|---|---|
| DATA-01 | 10-01 | Schema migration adds libraries table and library_id FK on audio_files |
✓ SATISFIED | _libraries.sql creates table; audio_files.sql has library_id FK; migration6MultiLibrary adds column to existing DBs |
| DATA-04 | 10-01 | All library operations are transactional — no partial state on failure | ✓ SATISFIED | Migration 6 wraps all changes between PRAGMA foreign_keys = OFF/ON, error handling returns on every step, backup created before changes |
| LSCAN-05 | 10-01 | Audio files are associated with their library via library_id foreign key |
✓ SATISFIED | audio_files.sql line 16: FOREIGN KEY(library_id) REFERENCES libraries(id); index at line 22-23; migration backfills existing rows |
| LIB-04 | 10-02 | Libraries are stored in SQLite (not TOML config) with CRUD through the UI | ✓ SATISFIED | 7 CRUD queries in libraries.sql, generated Go code in libraries.sql.go, Library model in models.go line 60-65 |
| LIB-05 | 10-02 | Existing single-directory config is migrated seamlessly to the libraries table on first run after upgrade | ✓ SATISFIED | readLibraryDirFromTOML reads existing config; migration6MultiLibrary step 5 creates default library; removeLibraryDirFromTOML cleans up config |
No orphaned requirements found — all 5 requirement IDs (DATA-01, DATA-04, LIB-04, LIB-05, LSCAN-05) are claimed by plans and satisfied.
Anti-Patterns Found
| File | Line | Pattern | Severity | Impact |
|---|---|---|---|---|
| — | — | — | — | No anti-patterns found |
No TODO/FIXME/PLACEHOLDER/HACK/XXX markers found in any database package files. No empty implementations or stub patterns detected.
Human Verification Required
1. Migration on Real v5 Database
Test: Run the application against a real existing v5 database with audio files and playlists Expected: Migration 6 runs silently — backup file created, libraries table populated from TOML config, all audio_files get correct library_id, playlist_tracks rebuilt with phantom metadata backfilled, app starts normally Why human: In-memory test DBs skip backup and TOML reading; real filesystem paths, file permissions, and TOML parsing edge cases can only be verified with a real database
2. TOML Config Cleanup
Test: After migration, check that config.toml no longer has DirectoryPath under [Library] section
Expected: DirectoryPath removed, other config sections preserved intact
Why human: TOML marshaling with map[string]any may reorder keys or change formatting — verify config file is still valid and readable
Gaps Summary
No gaps found. All 14 must-have truths verified, all 9 artifacts exist and are substantive, all 4 key links are wired, and all 5 requirements are satisfied. The build compiles cleanly (go build ./...), all tests pass (go test ./backend/database/... ./backend/playlist/...), and no anti-patterns were detected.
The migration implementation is thorough: 14-step migration function with SAFETY comments, pre-migration backup, TOML config read/cleanup, table rebuild with FK OFF/ON wrapping, phantom metadata backfill, and VIEW recreation. The sqlc queries are properly generated with LEFT JOINs, COALESCE fallback chains, and is_phantom computed columns.
