--- gsd_state_version: 1.0 milestone: v1.0 milestone_name: milestone status: in-progress last_updated: "2026-03-03T03:05:48Z" progress: total_phases: 3 completed_phases: 3 total_plans: 4 completed_plans: 4 --- # 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 3 complete — test infrastructure foundation with NewTestDB helper. **Milestone:** Consolidation (correctness, performance, code quality, UX polish, test coverage) ## Current Position **Phase:** 03-test-infrastructure (complete) **Plan:** 1/1 (complete) **Status:** In progress ``` Phase Progress: [###.....] 3/8 phases complete ``` ## Performance Metrics | Metric | Value | |--------|-------| | Phases complete | 3/8 | | Plans complete | 1/1 (Phase 3) | | Requirements delivered | 11/26 | | Tests added | 0 | | Bugs fixed | 9 | | 01-01 duration | 11 min | | 02-01 duration | 12 min | | 02-02 duration | 50 min | | 03-01 duration | 3 min | ## 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 | ### 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) - [ ] Design queue test architecture during Phase 4 planning (research flag) - [ ] Determine library scan test fixture strategy during Phase 5 planning (research flag) - [ ] 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 ### Quick Tasks Completed | # | Description | Date | Commit | Directory | |---|-------------|------|--------|-----------| | 001 | Multi-playlist import support | 2026-02-28 | 50c8a33 | [001-multi-playlist-import-support](./quick/001-multi-playlist-import-support/) | | 002 | Auto-rename duplicate playlists on import | 2026-02-28 | 8ba8bbe | [002-auto-rename-duplicate-playlists-on-import](./quick/002-auto-rename-duplicate-playlists-on-import/) | | 003 | Add multi-select to playlist view with context menu delete support | 2026-02-28 | c92ced2 | [3-add-multi-select-to-playlist-view-with-c](./quick/3-add-multi-select-to-playlist-view-with-c/) | | 004 | Add "set as default playlist" context menu option for single playlist selection | 2026-02-28 | 9971b63 | [4-add-set-as-default-playlist-context-menu](./quick/4-add-set-as-default-playlist-context-menu/) | | 005 | Add sort dropdown to playlist view | 2026-03-01 | 5c07485 | [5-add-sort-dropdown-to-playlist-view](./quick/5-add-sort-dropdown-to-playlist-view/) | | 006 | Remove list icon from playlist names, add favorites icon to default | 2026-03-01 | 3c19766 | [6-remove-list-icon-from-playlist-names-and](./quick/6-remove-list-icon-from-playlist-names-and/) | | 007 | Pin default playlist to top of playlist view | 2026-03-01 | e6378e1 | [7-pin-default-playlist-to-top-of-playlist-](./quick/7-pin-default-playlist-to-top-of-playlist-/) | | 008 | Add duplicate tracks dialog to playlist | 2026-03-01 | 917a79a | [8-add-duplicate-tracks-dialog-to-playlist](./quick/8-add-duplicate-tracks-dialog-to-playlist/) | ## Session Continuity ### Last Session **Date:** 2026-03-03 **What happened:** Executed Phase 3 Plan 01 — test infrastructure with shared applyPRAGMAs + NewTestDB helper **Where we stopped:** Completed 03-01-PLAN.md (all 2 tasks, verification passed) **Next action:** `/gsd-plan-phase 4` to create execution plan for Backend Unit Tests ### Context for Next Session - Phase 3 complete: TEST-01 and PERF-04 requirements delivered - `NewTestDB(t)` available in `database` package for all future DB tests - `applyPRAGMAs` shared between NewDB and NewTestDB — production PRAGMAs: foreign_keys, synchronous=NORMAL, cache_size=-8000, mmap_size=67108864 - `codegen-check` lefthook pre-commit hook hangs — use `LEFTHOOK=0` for commits - Ready for Phase 4 (Backend Unit Tests) --- *State initialized: 2026-02-27* Last activity: 2026-03-03 - Completed 03-01: Test infrastructure with shared applyPRAGMAs + NewTestDB *Last updated: 2026-03-03*
