### Context for Next Session
- Event codegen tool at backend/events/cmd/genevents/main.go
- LibraryConfigChanged gap automatically fixed by codegen
- `go generate ./...` completes in ~1.8s, codegen-check hook works end-to-end
- `codegen-check` pre-commit hook no longer hangs — can use LEFTHOOK=1 for commits
- Phase 6: 2/3 plans complete, SAFETY comments plan remaining
- Phase 6 fully complete: VIEW consolidation, event codegen, SAFETY comments
- All hand-crafted SQL documented with // SAFETY: comments
- lookupChunk now uses sqlc-generated LookupTrackMetaByPaths
- Ready for Phase 7 performance/startup optimization

# Phase 6 Plan 3: SQL Consolidation — lookupChunk Migration & SAFETY Comments Summary
**Migrated queue lookupChunk from fmt.Sprintf IN clause to sqlc-generated LookupTrackMetaByPaths query via track_metadata VIEW, and documented all 12 hand-crafted SQL statements with // SAFETY: comments**
## Performance
- **Duration:** 6 min
- **Started:** 2026-03-05T00:27:52Z
- **Completed:** 2026-03-05T00:34:10Z
- **Tasks:** 2
- **Files modified:** 7
## Accomplishments
- Replaced hand-crafted `fmt.Sprintf` IN clause in `lookupChunk` with sqlc-generated `LookupTrackMetaByPaths` query using `sqlc.slice()` and `track_metadata` VIEW
- Added `// SAFETY:` comments to all 12 hand-crafted SQL statements across 4 files (7 in search.go, 3 in library.go, 1 in rescan.go, 1 in persistence.go)
- All existing tests pass unchanged: database (15), library (13), queue (29) — all with `-race`
- Zero hand-crafted SQL in lookupChunk; the only remaining hand-crafted SQL in queue is `insertTrackBatch` (documented with SAFETY comment)
## Task Commits
Each task was committed atomically:
1. **Task 1: Migrate lookupChunk to sqlc with sqlc.slice()** - `2221a68` (feat)
2. **Task 2: Add SAFETY comments to all hand-crafted SQL** - `7dfe003` (docs)
## Files Created/Modified
- `backend/database/sql/queries/audio_files.sql` - Added LookupTrackMetaByPaths query using track_metadata VIEW
- `backend/database/sql/sqlcgen/audio_files.sql.go` - sqlc-generated Go code for LookupTrackMetaByPaths
- `backend/queue/persistence.go` - lookupChunk now uses sqlc query; insertTrackBatch has SAFETY comment
- `backend/database/search.go` - 7 SAFETY comments on all FTS5 operations
- `backend/library/library.go` - 3 SAFETY comments on FTS5 INSERT/DELETE in commitNewAudioFile and updateAudioFileMetadata
- `backend/library/rescan.go` - 1 SAFETY comment on FTS5 DELETE in clearAllLibraryData
## Decisions Made
- Used `sqlc.slice()` with `track_metadata` VIEW — the VIEW already provides the exact columns needed (id, file_path, title, artist_name), eliminating the need for an inline JOIN
- Preserved `lookupTrackMetaBatch` chunking at `maxSQLiteVars` (900) because `sqlc.slice()` does NOT auto-chunk large parameter lists
- Two-part SAFETY comment format: (1) why sqlc can't handle it, (2) what makes the query safe — makes it clear these are intentional exceptions, not oversights
- Cross-references in library.go/rescan.go point back to canonical search.go implementations to avoid divergent documentation
## Deviations from Plan
None - plan executed exactly as written.
## Issues Encountered
None
## User Setup Required
None - no external service configuration required.
## Next Phase Readiness
- Phase 6 complete: all 3 plans executed (VIEW consolidation, event codegen, SAFETY comments)
- All hand-crafted SQL documented; future maintainers can see why each exception exists
- Ready for Phase 7 (performance/startup optimization)
## Self-Check: PASSED
All created/modified files exist on disk. All commit hashes verified in git log.
