"""
RugCharts Intelligence Layer - 10 Immediate Wins
=================================================
Every feature uses existing DataBus infrastructure (Arkham, Helius, Redis, RAG).
No new dependencies. No ML training. Pure immediate value.

1. SMART MONEY FEED - What profitable wallets are buying right now
2. WHALE ALERT STREAM - Real-time large transaction detection
3. TOKEN LAUNCH SCANNER - New token detection + instant risk score
4. INSIDER PATTERN DETECTOR - Pre-pump accumulation detection
5. LIQUIDITY RISK MONITOR - LP health + pull detection
6. HOLDER HEALTH SCORE - Distribution analysis (Gini, concentration, freshness)
7. CROSS-CHAIN ENTITY INTEL - Same entity across chains via Arkham
8. RUG PATTERN MATCHER - RAG-powered similarity to known rug pulls
9. DEVELOPER REPUTATION - Deployer history across tokens
10. INSTANT TOKEN REPORT - One-call comprehensive intel on any token
