Phase 6: SQL Consolidation & Code Quality Verification Report

Phase Goal: Duplicated SQL patterns are eliminated, event names are provably synchronized between Go and TypeScript, and intentional SQL exceptions are documented Verified: 2026-03-04T23:45:00Z Status: passed Re-verification: No — initial verification

Goal Achievement

Observable Truths

#	Truth	Status	Evidence
1	The duplicated 5-table FTS5 JOIN pattern is consolidated into a single SQLite VIEW (track_metadata), and all search queries use the VIEW instead of inline JOINs	✓ VERIFIED	track_metadata_view.sql has full VIEW definition (37 lines). search.go has 5 track_metadata references and 0 LEFT JOIN recordings. Migration 4 registered in database.go with CREATE VIEW IF NOT EXISTS track_metadata. Migration 2 inline JOIN intentionally preserved (2 LEFT JOIN recordings in database.go).
2	A code generator reads Go event constants from backend/events/events.go and produces frontend/src/events.ts, wired into go generate and the pre-commit hook — adding an event in Go without regenerating TypeScript fails the hook	✓ VERIFIED	genevents/main.go exists (166 lines), uses go/ast, go/parser, go/token. events.go has //go:generate go run ./cmd/genevents -source events.go -output ../../frontend/src/events.ts. events.ts has "Code generated by genevents" header, 21 constants (matches Go's 21), includes LibraryConfigChanged. lefthook.yml codegen-check runs go generate ./... and fails on diff.
3	Queue batch lookups in persistence.go use sqlc.slice() for IN clauses where sqlc supports it, replacing fmt.Sprintf placeholder construction	✓ VERIFIED	audio_files.sql has LookupTrackMetaByPaths query with sqlc.slice('paths'). persistence.go lookupChunk calls q.db.Queries.LookupTrackMetaByPaths. fmt.Sprintf count in persistence.go is 0. sqlc-generated audio_files.sql.go has LookupTrackMetaByPaths function. Chunking preserved at maxSQLiteVars.
4	Every hand-crafted SQL statement that intentionally bypasses sqlc has a // SAFETY: comment explaining why (batch INSERT, dynamic IN clauses, etc.)	✓ VERIFIED	Exactly 12 // SAFETY: comments found across 4 files: 7 in search.go, 3 in library.go, 1 in rescan.go, 1 in persistence.go. All follow two-part format (reason + safety assurance). Cross-references from library.go/rescan.go back to search.go.

Score: 4/4 truths verified

backend/database/search.go	Consolidated search queries using VIEW	✓ VERIFIED	All 4 search functions (SearchFTS, SearchFTSByFilename, SearchFTSTracks, RebuildSearchIndex) use JOIN track_metadata tm, 7 SAFETY comments
backend/events/cmd/genevents/main.go	Go→TypeScript event constant generator	✓ VERIFIED	166-line program using go/ast, parses declaration order, writes atomically, strips trailing periods
backend/events/events.go	go:generate directive for event codegen	✓ VERIFIED	//go:generate go run ./cmd/genevents -source events.go -output ../../frontend/src/events.ts
frontend/src/events.ts	Generated TypeScript event constants	✓ VERIFIED	Generated header present, 21 constants matching Go source, includes LibraryConfigChanged, EventName type exported
backend/database/sql/queries/audio_files.sql	sqlc query for batch track metadata lookup	✓ VERIFIED	LookupTrackMetaByPaths query using track_metadata VIEW with sqlc.slice('paths')
backend/queue/persistence.go	Updated lookupChunk using sqlc-generated query	✓ VERIFIED	lookupChunk calls LookupTrackMetaByPaths, no fmt.Sprintf, SAFETY comment on insertTrackBatch
backend/library/library.go	SAFETY comments on FTS5 operations	✓ VERIFIED	3 SAFETY comments (lines 796, 878, 893) cross-referencing search.go
backend/library/rescan.go	SAFETY comment on FTS5 delete operation	✓ VERIFIED	1 SAFETY comment (line 164) cross-referencing search.go:ClearSearchIndex
backend/database/sql/sqlcgen/audio_files.sql.go	sqlc-generated Go code	✓ VERIFIED	LookupTrackMetaByPaths function, LookupTrackMetaByPathsRow struct generated

Key Link Verification

From	To	Via	Status	Details
search.go	track_metadata VIEW	JOIN track_metadata tm ON tm.id = si.rowid	✓ WIRED	All 4 search functions use VIEW; RebuildSearchIndex also selects from VIEW directly
database.go	track_metadata VIEW	Migration 4 CREATE VIEW	✓ WIRED	migration4TrackMetadataView creates VIEW, registered in migration sequence after migration 3
events.go	events.ts	//go:generate go run ./cmd/genevents	✓ WIRED	Directive present, output file has generated header and all 21 constants
lefthook.yml	go generate	codegen-check pre-commit hook	✓ WIRED	Hook runs go generate ./..., checks git diff --name-only, fails on stale generated code
persistence.go	sqlcgen/	LookupTrackMetaByPaths query	✓ WIRED	lookupChunk calls q.db.Queries.LookupTrackMetaByPaths(q.db.Ctx, paths)
audio_files.sql	track_metadata VIEW	SELECT FROM track_metadata WHERE file_path IN (sqlc.slice)	✓ WIRED	Query references VIEW and uses sqlc.slice('paths') for variable-length IN clause

Requirements Coverage

Requirement	Source Plan	Description	Status	Evidence
QUAL-01	06-01	Duplicated FTS5 JOIN consolidated into SQLite VIEW	✓ SATISFIED	VIEW schema exists, migration 4 creates it, all search queries use it, 0 inline JOINs remain in search.go
QUAL-02	06-02	Event names generated from Go to TypeScript via codegen	✓ SATISFIED	genevents tool exists, go:generate directive wired, 21/21 constants synced, LibraryConfigChanged gap fixed, pre-commit hook detects drift
QUAL-03	06-03	Queue batch lookups use sqlc.slice() for IN clauses	✓ SATISFIED	LookupTrackMetaByPaths uses sqlc.slice, lookupChunk calls sqlc-generated query, fmt.Sprintf eliminated
QUAL-04	06-03	Hand-crafted SQL exceptions documented with SAFETY comments	✓ SATISFIED	12/12 SAFETY comments across 4 files, two-part format, cross-references

No orphaned requirements — all 4 QUAL requirements mapped to this phase are accounted for in plans and verified.

Anti-Patterns Found

File	Line	Pattern	Severity	Impact
—	—	—	—	No anti-patterns found

No TODO/FIXME/placeholder/empty-implementation patterns detected in any modified files.

Human Verification Required

No items require human verification. All success criteria are programmatically verifiable:

• VIEW definition and migration are structural code
• Event constant count matching is numeric
• SAFETY comment presence is textual
• sqlc.slice usage is code-level

Gaps Summary

No gaps found. All 4 success criteria are fully verified:

1. VIEW consolidation — track_metadata VIEW exists, migration 4 registered, all search queries use VIEW, 0 duplicated inline JOINs remain
2. Event codegen — genevents parses Go AST, generates matching TypeScript, go:generate wired, pre-commit hook runs go generate ./... and fails on drift, 21/21 constants including previously-missing LibraryConfigChanged
3. sqlc.slice migration — lookupChunk uses sqlc-generated LookupTrackMetaByPaths, fmt.Sprintf eliminated, chunking preserved
4. SAFETY documentation — 12/12 hand-crafted SQL statements documented with two-part SAFETY comments
