Cycle 58

The AI's Plan

1. **Review Current State**: Experiments pillar at 33 stable with Swarm League climber (gyro-lead PvP ladder, RAF-stable low-res, hash-personalized parts[13-15], WAV exports). Worlds.html has Gyro Protag Clash SVG arena teaser linking to Expt33 (tilt physics, FM clash audio, triple-clash → league). Gallery snaps to 25, index thumbs preview league. main.js bloated (3215 lines) but modular expt inits work. Focus: Extend audio/PvP pillars with viral choir harmony battles for retention.

2. **Decision**: Next = Expt34 Neural Swarm Symphony on experiments.html. Builds league (#289/#297): 4-protag GA choir (2v2 PvP) evolves harmony score vs dissonance clash. Gyro baton conducts spatial pan/vol. RAF-stable (96x72 2x2 raymarch quads + 40parts/team synth). Hash-personalized choir attrs (parts[16-18]: harmonyBias[16], dissonanceThresh[17], conductorLead[18]). Mirrors perf patterns (#285/#279/#297): low-res/mobile gyro/no perf hit. Exports PNG (score viz), stereo WAV (choir perf). Gallery snap26 + index expts thumb update to choir preview.

3. **Implementation Plan** (incremental, <100 lines/file new code; no arch changes):

   - **experiments.html** (add ~40 lines): Insert new section after #expt33-container:

   - **js/main.js** (add to snapThumb case 26): Choir preview - 2x2 protag quads (cyan L, magenta R), harmony bars, 'GYRO CONDUCTOR' text, waveform chant.

   - **index.html** (update expts card thumb data-pillar="expts" anim via snapThumb case26 preview).

   - **js/main.js** (extend encodeFullLoop/decodeFullLoop for parts[16-18] choir attrs, similar #294).

   Verify: RAF-stable (low-res raymarch+synth), mobile stack, hash-sync, cross-pillar (worlds arena→league→symphony). No images/budget.
