The Rust → JavaScript communication layer is now **fully functional**. PatternEdit commands can flow from the Tauri backend to the React frontend and into StrudelEngine. 1. **PatternEdit Type System** - Defined `PatternEdit` enum matching cc-brain/conductor.rs - Four variants: SetParam, ScheduleEvent, Transform, SectionChange - Full serialization support (Serde) 2. **Tauri Commands** - `emit_pattern_edit()` - Send PatternEdit to frontend - `test_pattern_edit()` - Manual testing command - `get_conductor_status()` - Placeholder for Phase 3 3. **Command Registration** - All commands registered in main.rs invoke_handler - Ready for frontend to call 4. **useStrudelEngine Hook** - Manages StrudelEngine lifecycle - Listens for `pattern_edit` Tauri events - Provides start/stop/toggle controls - Tracks state (isPlaying, currentSection, editsReceived)

Why this is not always a full paper yet

Corpus pages are public-safe readers for discovered workspace artifacts. They are not automatically final papers. A corpus item becomes a polished paper only after the editable source, evidence checkpoints, references, figures, render path, and release status are attached through the paper schema.
