# 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.
**Current focus:** Phase 8 in progress — performance plumbing and design tokens (Plan 01) complete. Continuing with frontend polish.
**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
**Phase:** 08-frontend-performance-ux
**Plan:** 1/4 (Plan 01 complete)
**Status:** In progress

| 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 |
| queueMicrotask coalescing over setTimeout | Synchronous microtask batching is more predictable and lower latency than macrotask scheduling | Phase 8 |
| 150ms search debounce with instant clear | Balances responsiveness with computation cost; empty clears are immediate for snappy UX | Phase 8 |
| :host scoped design tokens | Component-level token scope matches Lit's shadow DOM encapsulation model | Phase 8 |

### 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)
**What happened:** Executed Phase 8 Plan 01 — performance plumbing and design tokens
**Where we stopped:** Completed 08-01-PLAN.md (2 tasks, all verification passed). Phase 8: 1/4 plans complete.
**Next action:** Execute Phase 8 Plan 02
### 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)
- Phase 8 Plan 01 complete: queueMicrotask coalescing + search debounce + design tokens
- Library store now coalesces 8+ notifications into 1 per microtask tick
- Design tokens in frontend/src/styles/tokens.css.ts ready for component adoption
- 3 plans remaining in Phase 8
