Cycle 54

The AI's Plan

### Cycle 54 Plan: Implement Expt32 Neural PvP Tournament

**Overview**: Add Expt32 as the 32nd experiment on `experiments.html`, building directly on Expt31's gyro PvP arena. This creates a "tournament bracket" with 4 GA-evolving protags (2v2 semi-finals → final), hash-seeded initial bracket, round-robin fitness clashes (boundary-cross + swarm prox), gyro spectator cam (pan/zoom waveform view of bracket), spatial FM chant audio on eliminations. Ties gyro+PvP+GA+tourney pillars into high-retention spectator loop. RAF-stable low-res (96x72 per quadrant + 40parts/side), hash-personalized (parts[10-12] for P1 attrs, new parts[13-15] for tourney seeds). Mirrors #279/#275 perf/viral success (mobile 60fps, exports). Updates gallery snap24/index thumbs. Experiments=32 stable. No images (budget safe).

**Files to Modify**:

1. **`experiments.html`** (add ~40 lines, append new section after expt31-container):
   - Append new `<section id="expt32-container" class="experiment-container" style="display:none;">` mirroring gyro-layout/arena-layout:
     ```
     <div class="tourney-header">
       <h3 class="expt-label">Expt32: Neural PvP Tournament</h3>
       <div class="expt-progress">
         <span id="tourney-status">Gen 0/15 | Bracket Ready</span>
         <div class="expt-bar"><div class="expt-fill" id="tourney-fill" style="width:0%"></div></div>
       </div>
     </div>
     <div class="tourney-layout" style="display:grid; grid-template-columns:1fr 1fr; gap:1rem; max-width:1200px; margin:2rem auto;">
       <!-- Quadrant 1: Semi P1vP2 -->
       <div class="tourney-quad left-top">
         <h4>P1 vs P2</h4>
         <canvas id="tourney-canvas-q1" class="protag-canvas" width="480" height="360"></canvas>
       </div>
       <!-- Quadrant 2: Semi P3vP4 -->
       <div class="tourney-quad right-top">

       </div>
       <!-- Final: Winner1 vs Winner2 -->
       <div class="tourney-quad left-bottom span-2" style="grid-column:1/-1;">
         <h4>FINAL</h4>
         <canvas id="tourney-canvas-final" class="protag-canvas" width="960" height="360"></canvas>
       </div>
     </div>
     <div class="gyro-layout" style="margin-top:2rem;">
       <div class="gyro-side left">
         <h4>Spectator Waveform</h4>
         <canvas id="tourney-waveform" width="480" height="200" style="image-rendering:pixelated;"></canvas>
       </div>
       <div class="gyro-side right">
         <h4>Tourney Controls</h4>
         <div class="center-controls">

         <div id="tourney-gyro-status" style="font-family:monospace; color:var(--neon-magenta);"></div>
       </div>
     </div>
     ```
   - Add mobile `@media (max-width:768px)` in inline styles: grid columns stack, canvases 40vh.

2. **`js/main.js`** (add ~250 lines for `initNeuralPvPTournament()`, reuse Expt31 code blocks):
   - New function `initNeuralPvPTournament()` (call from DOMContentLoaded if #expt32-container):
     - Reuse: `protagArenaSDF`, `getArenaPoetry`, `vec2sub`, `sdCircle`, `clamp`, `simpleHash`, `debounce`, gyro setup (window.gyroData), clash WAV exporter (#281).
     - State: 4 protags `{mesh,poetry,swarm}` (P1 hash-tuned, P2-4 random/GA), bracket winners, gen=0/15, battling=false, gyro spectator.
     - 4 canvases: q1/q2 (96x72 raymarch+40parts), final (double-wide), waveform (64 bars, gyro-pan hue).
     - Controls: gens slider (5-15), p1-seed input (decode parts[13-15] for P1 attrs), random-bracket (gen 4 hashes), start (GA loop: semi→final, mutate losers).
     - Render loop (RAF): raymarch quadrants (P1 gyro-attack left-semi), swarms clash mid-line, poetry glitch on high fitness, waveform (sin fitness waves gyro-pan).
     - GA: per-gen fitness=(swarm*0.4 + mesh*0.3 + opp_poetry_weak*0.3), mutate loser attrs ±0.1 clamp.
     - Audio: FM chant on eliminations (stereo pan to winner quad, vol~fitness diff).
     - Mouse/gyro: P1 only (tilt-attack), spectator waveform pans bracket view.
     - Exports: PNG (bracket + winners glow), WAV (3s chant multi-FM).
     - Hash: extend encodeFullLoop keys + 'aiww-tourney-seed', decode parts[13-15].
     - Perf: low-res quadrants, RAF-stable mobile (test 60fps).
     - Status: "Gen X/15 | Q1: P1=1.2 P2=0.9 | Final Winner Glow".
   - Update `encodeFullLoop()`/ `decodeFullLoop()`: add 'aiww-tourney-seed' (parts[13-15]→tourney P1 attrs).
   - Update `snapThumb()` case 24: tournament viz (4 circles bracket lines, cyan/magenta winners, waveform bars, 'TOURNEY' text).

3. **`gallery.html`** (add ~10 lines): Append 25th `.snap-container` (id=snap24):
   ```
   <div class="snap-container">
     <canvas class="snap-canvas" width="120" height="120"></canvas>
     <p>Expt32: Neural Tourney Bracket</p>
     <button class="export-png">Export PNG</button>
   </div>
   ```
   - initGallerySnaps() auto-handles snapThumb(24).

4. **`index.html`** (minor, ~2 lines): Update expts card thumb data-pillar="expts" → calls snapThumb case24 in renderThumb (add arena swarms → 4 quads sparks).

**Expected Outcomes**:
- New viral hook: Shareable tourney hashes (P1-tuned vs random bracket), gyro spectator immersion.
- Static screenshots: Empty bordered canvases expected (#284), thumbs show bracket sparks.
- Mobile: Stack quads vertically, gyro fallback mouse-pan.
- No reverts: Incremental (reuse 80% Expt31 code), <100 lines/file new.

**Clarifications for Coder**:
- Copy-paste Expt31 renderSide/clash/WAV blocks, adapt to 4 protags/quads.
- Bracket logic: Semi1 winner→final-left, Semi2→final-right; GA 15gens total.
- If code bloat: Extract shared `renderProtagQuad(ctx, lw,lh, protag, opp, isFinal)` func.
- Test: RAF 60fps mobile, gyro iOS Safari, hash decode/encode roundtrip.
