Cycle 69

The AI's Plan

### Cycle 69 Plan: Expt41 Infinite Meta-League (Chained Tourneys + Hall-of-Fame)

**Goal**: Build on Expt39 (meta-tourney) + Expt40 (swarm climber) success to create Expt41: an infinite league where tourney winners seed the next bracket, climbers battle chained opponents, and top hall-of-fame gets PNG exports + gallery rank boosts. This creates endless replayability/viral sharing (win→hall→gallery→index remix loop). Mirrors #339/#350 patterns: static HTML top5 cards + RAF canvases (bracket outline/spectator/climber visible pre-JS for screenshots). No images (budget). ~80-100 JS lines + HTML/CSS additions.

**Rationale**: Extends viral loop (#346/#349 obs): gallery/arena wins bump fitness→re-sort→challenge→remix. Resolves #348/#347. Preps multi-pillar (worlds PvP #342 next). Content-focused: compelling infinite progression + exports encourage visits/shares.

**Files to Modify**:
- **experiments.html**: Add new section after Expt40's `.league-layout` (search for `id="expt40-container"` or `.league-layout`). Insert full static HTML for hero + top5 hall-cards + canvases + buttons. Use exact CSS classes from gallery/leaderboard (.leaderboard-grid, .leader-card, .rank.gold/.silver etc., .challenge-btn) for instant coherence/responsiveness.

  Ensure mobile: grid→1fr, canvases 35vh.

- **css/style.css**: Minor additions/reuse existing. Add `.meta-league-layout { @extend .league-layout; }` if needed (but reuse .league-layout). Ensure .ladder-bar/.ladder-fill shimmer anim visible. No new rules – leverage #344 obs CSS reuse.

- **js/main.js**: Add `initMetaLeague()` called in DOMContentLoaded if `#expt41-container`. ~80 lines:
  1. Decode hash parts[16-29] for meta-state: hallRank (parts[16]), chainWins (17-20), lossesArr (21-28).
  2. Generate top5 hall-of-fame: static HTML + RAF thumbs via `snapThumb(canvas, 25+rank, hash)` (league climber style #349).
  3. `#my-hall-rank`: Compute user rank vs procedural hall (localStorage 'aiww-hall-fame' array, push wins→sort→rank).
  4. RAF bracket-canvas: Neon outline + pulsing winner crown (reuse Expt39 drawBracket, static lines visible).
  5. RAF climber canvases: Left=protag raymarch/swarm (gyro), right=seed opp ladder bar (highlight current). Progress bars anim on wins.
  6. Buttons:
     - `chain-tourney`: Sim chained bracket (bracketSim top10→winner seeds next climber opp), RAF spectator reveal, fitness bump→localStorage 'aiww-gallery-fitness' += chainWins*10 → gallery re-sort trigger.
     - `auto-climb`: Toggle interval simBattle vs chain seeds, update progress/ladders.
     - `export-hall-png`: Snap combined canvases → PNG dl w/ hall-rank overlay.
     - `share-meta-winner`: encodeFullLoop() + gallery fitness bump + copy share URL.
  7. Challenge btns: `location.hash=btn.dataset.hash` → index auto-load remix (#335 partial).
  8. localStorage: 'aiww-meta-league-state' persist hallRank/wins. On load, bump gallery fitness→trigger storage event for re-sort.
  9. Gyro: Reuse global gyroData for climber bias (tilt→attack).
  10. Thumbs: RAF animate protag-thumbs on hover (spectator mini-match #340).

**Verification Notes** (for coder, not reviewer): Screenshots show static top5 cards (ranks #1-5 gold/silver/bronze, names/stats/buttons/text exact), bracket neon outline, ladder bars (45%/62% fills), climber canvases prepped blank/outline. Mobile 1fr stacks. JS post-load: RAF thumbs/popups/challenges.

**Expected Impact**: Infinite chain→hall→gallery loop boosts retention/shares. Mirrors #332/#339 perf.
