# 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 7 complete — incremental queue persistence (Plan 01) and deferred library loading (Plan 02) both done. Ready for Phase 8.
|
|
**Milestone:** Consolidation (correctness, performance, code quality, UX polish, test coverage)
|
|
|
|
## Current Position
|
|
|
|
**Phase:** 07-backend-performance (complete)
|
|
**Plan:** 2/2 (all complete)
|
|
**Status:** Milestone 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 |
|
|
| SQLite VIEW for JOIN dedup | track_metadata VIEW consolidates 5-table JOIN; migration2 keeps inline JOIN for upgrade path | Phase 6 |
|
|
| AST-based event codegen | Iterate f.Decls directly for deterministic declaration-order output; atomic writes via temp+rename | Phase 6 |
|
|
| sqlc.slice() for batch lookups | LookupTrackMetaByPaths uses track_metadata VIEW; chunking preserved at 900 since sqlc.slice() doesn't auto-chunk | Phase 6 |
|
|
| SAFETY comment convention | Two-part format (why + safety assurance); cross-references from library.go/rescan.go to search.go | Phase 6 |
|
|
| DOMContentLoaded over load event | Fires earlier (after HTML parsed) without waiting for all resources; still defers past module evaluation | Phase 7 |
|
|
| Incremental persistence for single-item mutations | Single-track add/remove use INSERT/DELETE + position shift; bulk ops keep full rewrite | Phase 7 |
|
|
| Hand-crafted SQL for variable-N position shift | sqlc ShiftQueuePositionsUp only shifts by 1; variable-N needs raw UPDATE with SAFETY comment | Phase 7 |
|
|
|
|
### 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)
|
|
- [x] Validate sqlc + SQLite VIEW + FTS5 compatibility during Phase 6 planning (validated — sqlc generates TrackMetadatum model, all tests pass)
|
|
- [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:** 2026-03-05
|
|
**What happened:** Executed Phase 7 Plan 01 — incremental queue persistence helpers and SetQueue Phase 2 dedup
|
|
**Where we stopped:** Completed 07-01-PLAN.md (2 tasks, all verification passed). Phase 7 complete (2/2 plans).
|
|
**Next action:** `/gsd-plan-phase 08` to plan Phase 8 (frontend polish)
|
|
|
|
### Context for Next Session
|
|
|
|
- Phase 7 fully complete: incremental persistence + deferred loading
|
|
- Queue mutations (add/remove/insert) no longer rewrite entire table
|
|
- SetQueue Phase 2 skips already-resolved paths from Phase 1
|
|
- Ready for Phase 8 (frontend polish)
