# Phase 10: Schema & Migration Verification Report
**Phase Goal:** The database supports multiple libraries and phantom tracks — existing users upgrade seamlessly
**Verified:** 2026-03-09T09:55:00Z
**Status:** passed
**Re-verification:** No — initial verification
## Goal Achievement
### 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 |
| 3 | Fresh database creates playlist_tracks with nullable audio_file_id and phantom metadata columns | ✓ VERIFIED | `playlist_tracks.sql` line 4: `audio_file_id INTEGER` (nullable), lines 6-11: all 6 phantom columns, line 13: `ON DELETE SET NULL` |
| 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 |
| 10 | Audio file queries accept library_id parameter | ✓ VERIFIED | `audio_files.sql` lines 131-134: GetAudioFilesByLibrary and CountAudioFilesByLibrary queries |
| 11 | Migration tests verify upgrade path from v5 to v6 | ✓ VERIFIED | `database_test.go`: TestMigration6FreshDB (201 lines), TestMigration6LibraryQueries, TestMigration6PhantomPlaylistTracks, TestMigration6AudioFilesLibraryFK, TestMigration6TrackMetadataViewHasLibraryID — all 5 tests PASS |
| 12 | Migration tests verify fresh database creates correct schema | ✓ VERIFIED | TestMigration6FreshDB checks: libraries table exists, audio_files has library_id, playlist_tracks has all 6 phantom columns + nullable audio_file_id, track_metadata VIEW has library_id, user_version >= 6 |
| 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 |
**Score:** 14/14 truths verified
### Required Artifacts
#### Plan 01 Artifacts
| Artifact | Expected | Status | Details |
|----------|----------|--------|---------|
| `backend/database/sql/schemas/_libraries.sql` | Libraries table DDL for fresh installs | ✓ VERIFIED | 7 lines, CREATE TABLE with id, name, path (UNIQUE), created_at |
| `backend/database/sql/schemas/audio_files.sql` | Updated audio_files DDL with library_id FK | ✓ VERIFIED | 24 lines, library_id column + FK + index |
| `backend/database/sql/schemas/playlist_tracks.sql` | Updated playlist_tracks DDL with nullable audio_file_id and phantom columns | ✓ VERIFIED | 21 lines, nullable audio_file_id, SET NULL FK, 6 phantom columns, 2 indexes |
| `backend/database/sql/schemas/track_metadata_view.sql` | Updated VIEW with library_id in SELECT | ✓ VERIFIED | 38 lines, af.library_id as last column in SELECT |
| `backend/database/database.go` | migration6MultiLibrary function + backup logic | ✓ VERIFIED | 1155 lines total, migration6MultiLibrary (lines 718-1031), backupDatabase (lines 678-710), readLibraryDirFromTOML (lines 1035-1077), removeLibraryDirFromTOML (lines 1083-1154) |
#### Plan 02 Artifacts
| Artifact | Expected | Status | Details |
|----------|----------|--------|---------|
| `backend/database/sql/queries/libraries.sql` | sqlc query definitions for libraries CRUD | ✓ VERIFIED | 22 lines, 7 queries: CreateLibrary, GetLibrary, GetLibraryByPath, GetAllLibraries, UpdateLibraryName, DeleteLibrary, CountLibraries |
| `backend/database/sql/queries/playlists.sql` | Updated playlist queries with phantom column support | ✓ VERIFIED | 149 lines, AddPlaylistTrack with 9 params, LEFT JOINs, COALESCE fallback chains, is_phantom, GetTrackPhantomMetadata helper |
| `backend/database/sql/sqlcgen/libraries.sql.go` | Generated Go code for library queries | ✓ VERIFIED | 131 lines, auto-generated with all 7 query functions |
| `backend/database/database_test.go` | Migration 6 integration tests | ✓ VERIFIED | 589 lines, 5 test functions all PASS |
### 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.
