## Project Reference
**Core value:** The music player works reliably and feels solid — every interaction is correct, responsive, and trustworthy.
**Current focus:** Phase 8 in progress — Plans 01-02 complete. Virtualizer repeat() migration done. Continuing with frontend polish.
**Current focus:** Phase 8 in progress — Plans 01-03 complete. renderTrackRow/renderTrackItem optimized with classMap. One plan remaining.
**Milestone:** Consolidation (correctness, performance, code quality, UX polish, test coverage)
## Current Position
**Phase:** 08-frontend-performance-ux
**Plan:** 2/4 (Plans 01-02 complete)
**Plan:** 3/4 (Plans 01-03 complete)

| Inline repeat() keys over gridKeyFunction | Dead method removal; key logic is cleaner inline in repeat() calls | Phase 8 |
| classMap over array filter/join | Eliminates per-row array allocation; classMap diffs internally for efficient DOM updates | Phase 8 |

### Context for Next Session
- Phase 8 Plans 01-02 complete
- All 7 lit-virtualizer instances now use repeat() with stable entity keys
- DOM recycling enabled for scrolling/filtering in large libraries
- 2 plans remaining in Phase 8
- Phase 8 Plans 01-03 complete
- classMap directive used in all render hot paths (track-list + queue-panel)
- Search highlight short-circuits when term is empty
- 1 plan remaining in Phase 8
