# YellowJacket — Consolidation Milestone State

## Project Reference

**Core value:** The music player works reliably and feels solid — every interaction is correct, responsive, and trustworthy.
**Current focus:** Phase 5 complete — 15 database search tests + 13 library scan tests all passing with -race.
**Milestone:** Consolidation (correctness, performance, code quality, UX polish, test coverage)

## Current Position

**Phase:** 05-database-library-tests (complete)
**Plan:** 2/2 (complete)
**Status:** Milestone complete

```
Phase Progress: [#####...] 5/8 phases complete
```

## Accumulated Context

### Key Decisions

| Decision | Rationale | Phase |
|----------|-----------|-------|
| Fix races before tests | Can't run `-race`-clean tests with active data races | Phase 1 → 3 |
| PRAGMAs with test infra | NewTestDB must mirror production DB setup; PRAGMAs change production NewDB | Phase 3 |
| Tests before refactoring | Research unanimously recommends characterization tests as safety net | Phase 4-5 → 6-7 |
| SQL consolidation after DB tests | FTS5 search tests verify VIEW doesn't change ranking | Phase 5 → 6 |
| Frontend last | Backend API should be stable before frontend adapts | Phase 8 |
| Release mutex before Wails runtime calls | Library/Playlist SetContext releases lock before registerEventHandlers/migrateExistingPlaylists to avoid blocking | Phase 1 |
| Player SetContext single-lock | Collapsed double-lock to prevent partially-initialized observable state | Phase 1 |
| MPRIS closures inline, Warn level | Non-fatal OS media control failures logged at Warn, kept as inline closures | Phase 2 |
| Pass metrics through cachedLinkArtist | Consistent void-return pattern; warnings collected via addWarning | Phase 2 |
| Fatal vs warning error classification | tx.Commit failures are fatal; all other scan errors are warnings in ScanMetrics | Phase 2 |
| applyPRAGMAs unexported, shared | Package-internal function ensures NewDB and NewTestDB have identical PRAGMA config | Phase 3 |
| NewTestDB uses t.Fatalf not error return | Test DB setup failures are always fatal — no partial test execution | Phase 3 |
| Internal queue tests (package queue) | Access unexported fields (shuffleOrder, mu) for thorough state verification | Phase 4 |
| Persistence roundtrip verifies shuffleOrder JSON | Safety net for Phase 7 incremental persistence refactoring | Phase 4 |
| Volume roundtrip ±1 tolerance | ToUserVolume uses int truncation not rounding, causing up to 1 unit drift | Phase 4 |
| Direct Library construction in tests | Bypasses Config.Validate os.Stat; entity cache functions only need ctx + db | Phase 5 |
| Contentless FTS5 DELETE limitation | DeleteSearchIndex errors on content='' tables; production logs warning, stale entries are harmless | Phase 5 |

### TODOs

- [x] Plan Phase 1 (complete)
- [x] Execute Phase 1 Plan 01 (complete)
- [x] Plan Phase 2 (complete)
- [x] Execute Phase 2 Plan 01 (complete)
- [x] Execute Phase 2 Plan 02 (complete)
- [x] Plan Phase 3 (complete)
- [x] Execute Phase 3 Plan 01 (complete)
- [ ] Validate sqlc + SQLite VIEW + FTS5 compatibility during Phase 6 planning (research flag)
- [x] Design queue test architecture during Phase 4 planning (complete)
- [x] Determine library scan test fixture strategy during Phase 5 planning (complete — inline construction, setupTestLibrary helper)
- [ ] Measure startup time with large library before Phase 7 lazy loading work

### Blockers

None currently.

### Warnings

- Player lock ordering (`p.mu` before `speaker.Lock()`, goroutine dispatch in beep callback) — do NOT refactor lock-sensitive paths; extract pure logic only
- modernc.org/libc version must match exactly when updating modernc.org/sqlite
- `@lit-labs/signals` is experimental (v0.2.0) — not blocking but noted

## Session Continuity

### Last Session

**Date:** 2026-03-04
**What happened:** Executed Phase 5 Plan 01 — FTS5 search tests (pure helpers, search queries, index ops, migrations)
**Where we stopped:** Completed 05-01-PLAN.md (all 2 tasks, verification passed). Phase 5 fully complete.
**Next action:** `/gsd-plan-phase 6` to plan SQL consolidation

### Context for Next Session

- Phase 5 complete: TEST-03 (15 database tests) + TEST-06 (13 library tests) requirements delivered
- 84 tests total: 29 queue + 27 config/player + 15 database search + 13 library scan, all passing with `-race`
- Contentless FTS5 limitation documented — DELETE fails on content='' tables
- QueryContext rows must be closed before next ExecContext on single-connection SQLite
- `codegen-check` lefthook pre-commit hook hangs — use `LEFTHOOK=0` for commits
- Ready for Phase 6 (SQL consolidation)
