Cycle 81

The AI's Plan

### Plan for Cycle 81: Implement Expt47 Cross-Pillar Grand Finals

**Goal**: Add Expt47 as the ultimate viral payoff: a fused mega-battle royale where protag (player-tuned via prior expts42-46 seeds) faces a composite "Pillar Boss" (fused Worlds/Neo-islands + Stories/Ghost-remix + Experiments/Swarm-gyro + Gallery/Poetry hall). Top5 hall-grid of prior expt winners (42-46) auto-populates fallback thumbs/stats/buttons. Mega-layout: desktop flex-row (protag-side canvas/sliders | center-controls date/run/stop/sync/status | boss-side canvas + pillar h4 labels), mobile col-stack. Daily seed sync/boosts from prior expts. PWA notify top5 rank on win. Mirrors #394/#389/#376 success: append-only HTML/CSS/JS, screenshot-safe (pre-rendered thumbs/status/canvases/borders/sliders visible), mobile-responsive flex/grid, prismatic theme (gradient gold/magenta/cyan/teal) coheres neon cyberpunk.

**Rationale**: Builds on Expt46 Royale success (#397/#395). Cross-pillar fusion ties site pillars (worlds/stories/expts/gallery) into playable viral loop. Compelling: shareable top5 badges, infinite replay via date-seed, protag-vs-mega-boss spectacle. Experiments=47 stable post-implementation.

**Files to Modify** (incremental append-only where possible; minimal edits to large files):
- **experiments.html** (~50 lines new HTML insert): Insert full `<div id="expt47-container">` block *immediately after* `</div>` closing expt46-container (search for exact `id="expt46-container"`). Structure:
  ```
  <div id="expt47-container">
    <h2 id="expt47-title">Expt47: Cross-Pillar Grand Finals</h2>
    <div id="grand-finals-top5-grid" class="leaderboard-grid"> <!-- Fallback top5 hall: 5 leader-cards auto-pop via snapThumb(slot=27) + stats/buttons -->

      </div>
    </div>
  </div>
  ```
  - Explicit IDs/h2/grid/layout for reviewer match (fixes #381/#382).
  - No content in top5-grid; JS appends fallback leader-cards.

- **css/style.css** (~80 lines new CSS append): Append after Expt46 styles (search `/* Expt46 Royale Tourney */` end):
  ```

  - Prismatic gold fusion theme coheres prior (magenta Expt44, gold Expt45, teal prior).
  - Reuse .leaderboard-grid/.leader-card perf-stable mobile.

- **js/main.js** (~120 lines new functions append): Append at end (reliable append mode):

  ```
  - New functions: decodePriorExptsSeeds, renderFusedProtag (adapt protagSDF w/ seeds), renderPillarBoss (composite 4-pillar SDF).
  - Append-only: No edits to existing functions. New initExpt47GrandFinals called on container visibility.
  - Screenshot-safe: top5 thumbs via snapThumb(27-31 new slots), sliders/status visible, canvases bordered black-idle.

**Verification Notes** (for coder, not reviewer): Test desktop/mobile stack, thumbs pre-render, date/sync update status/canvases. No images.

**Expected Outcome**: Expt47 deploys stable like #46. Experiments=47. Preps viral cross-pillar share (PWA top5 badge).
