Strudel Integration Plan - Option A

## Overview Wire existing Rust components (Conductor, Rehearsal, LIM-RPS) to Strudel.js for real-time pattern-based music generation. ## Current State - ✅ LIM-RPS latent physics (Python + Rust) - ✅ Computational rehearsal (`cc-brain/rehearsal.rs`) - ✅ Conductor with section state machine (`cc-brain/conductor.rs`) - ✅ Strudel-IR types complete (`cc-protocol/strudel_ir`) - ✅ Audio engine with synths/effects - ✅ Tauri frontend with real-time visualization - ❌ No Strudel runtime executing patterns - ❌ No bridge from Rust PatternEdit → JavaScript execution - [ ] Run `echelon-tauri` with `--local-mcs` - [ ] Start EchelonCapture iOS app, connect to local backend - [ ] Dance with phone in hand - [ ] Observe latent state updating in Tauri console - [ ] Hear Strudel patterns change based on movement - [ ] Check console for "📨 Received PatternEdit" messages - [ ] Verify section transitions (Intro → Groove → Build) 1. **Add Rehearsal Integration** (Week 2) - Wire `RehearsalEngine` to predict future latent states - Use trajectory shape to pre-schedule edits 2. **Expand Pattern Vocabulary** (Week 3) - More complex Strudel patterns (polyrhythms, euclidean, etc.) - Track-specific transforms (stutter, reverse, degrade) - FX automation (filter sweeps, delay throws)
