RMI Unified RAG Ingestion Pipeline - v2.0
==========================================
Multi-source, auto-throttling, permanence-guaranteed RAG ingestion.

Sources (all FREE):
  1. GitHub scam databases - ScamSniffer, MetaMask, CryptoScamDB, ChainPatrol
  2. News articles - auto-ingested from news_service.py
  3. Research papers - arxiv crypto/blockchain papers
  4. Existing scripts - Rekt hacks, Etherscan labels, SIGMOD, WHALEGOD
  5. Token scan results - auto-fed from DataBus scanner

Architecture:

              │   RAG API (/rag/ingest)  │
              │   Redis vector store     │
              │   9 collections          │
              └──────────────────────────┘

Backpressure - prevents overload:
  - Max 50 docs per cycle (configurable)
  - Min 2s between API calls
  - Redis key: rmi:rag:ingest:last_run (prevents concurrent runs)
  - Stops early if Redis memory > 1.5GB

Permanence:
  - All security data → TTL=0 (permanent)
  - News articles → TTL=30d (self-cleaning)
  - Token analysis → TTL=90d (auto-expiring)

Run: docker exec rmi-backend python3 /app/scripts/unified_rag_ingest.py
Cron: 0 3 * * * (daily at 3AM, low traffic)
