# YellowJacket — Project State

## Project Reference

See: .planning/PROJECT.md (updated 2026-03-06)

**Core value:** The music player works reliably and feels solid — every interaction is correct, responsive, and trustworthy.
**Current focus:** v1.1 Features & Extensibility — defining requirements

## Current Position

Phase: Not started (defining requirements)
Plan: —
Status: Defining requirements
Last activity: 2026-03-06 — Milestone v1.1 started

## Accumulated Context

### Key Decisions

Decisions from v1.0 are archived in PROJECT.md Key Decisions table. Key patterns to carry forward:

- Mutex-protected setter pattern (lock → write → release → callbacks)
- SAFETY comment convention for hand-crafted SQL
- AST-based codegen for cross-language constant sync
- Design tokens via `:host` scoped CSS custom properties
- queueMicrotask coalescing for store notifications
- `.renderItem` + `.keyFunction` (not `repeat()` children) for lit-virtualizer

### Warnings (carry forward)

- 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
