Title: Feature: Secure Fibonacci Multiplier for Heavy Ranker – Positivity, Fair Tiers, Allegiance Booster (Post-c54bec0)

Body: Following commit c54bec0 (Sept 9, 2025), I propose a secure, user-friendly enhancement to the Heavy Ranker (projects/home/recap/ranking.py) to boost positivity, balance tiers, block bots, and foster user allegiance to X, aligning with goals of uplifting small accounts, reducing negativity, and integrating Grok AI (#0, #1, #6). The Fibonacci-based approach creates a harmonic synergy, rewarding quality content while ensuring fairness for all users.

Proposal:

• Fibonacci Boosts: Amplify positive sentiment (2.0 max) and thoughtful replies (>10 words, 8.0 max) with Fib(n)/5.0. Caps: small (<1K followers) 2.5x, median (1K–100K) 2.0x, big (>100K) 1.5x with volatility penalty.
• Bot-Proof Shield: Downrank fakes with 1/(Fib(n)+1), cutoff at fakeness >8 (score * 0.01). Signals: like velocity (>150), reply diversity (<0.3), account age (<7 days), reply length variance. Randomized weights (0.8–1.2x) block bot counterattacks.
• Tiers:
  • Small: 2.5x cap, 0.2% “Fibonacci Spark” (+1 level) for discovery.
  • Median: 2.0x cap, 1.1x stability.
  • Big: Volatile (0.7x for low quality), privileges (halved penalties for 5-hour activity or 2-week day-off with 2x ranking boost).
• RMS Prediction: Pre-boosts high early engagement.
• Transparency: Logs boost, penalty, tier, privileges, anti-bot signals, and user-friendly messages (e.g., “Great replies boosted your post!”) for “Why This Post?” UI.
• Allegiance Booster: Rewards thoughtful content, softens bot detection to avoid penalizing genuine users, and uses Spark to engage new voices, fostering loyalty to X.

Why It Fits:

• Boosts positivity (leverages reply=13.5, reply_engaged_by_author=75.0) for “unregretted user-seconds” (#28).
• Uplifts small accounts with equitable boosts and Spark (#6).
• Anti-gameable with precise bot detection (#0).
• Encourages allegiance via transparency, fair rewards, and a fun Fibonacci approach, optimized for PyTorch and Grok AI (#1).
