## How It Works

The verification pipeline has 10 steps:
1. **Ingest** — Poll 122 RSS feeds across 26 countries every 30 minutes
2. **Cluster** — Group articles about the same event using embedding similarity
3. **Extract & Decompose** — Break claims into atomic verifiable facts
4. **Cross-Verify** — Check claims across sources + Google Fact Check API
5. **Bias Analysis** — Tag each source's political bias via Media Bias/Fact Check data (10,000+ outlets)
6. **Adversarial Debate** — 3 AI perspectives (Progressive, Conservative, Libertarian) + Devil's Advocate + 2-model ensemble
7. **Synthesize** — Chief editor agent produces balanced, cited article
8. **Self-Verify (CoVe)** — Separate AI reviews synthesis against original sources
9. **Entailment Check (NLI)** — Detects claims not entailed by source material
10. **Web Verification (SAFE-style)** — Searches web for contradicting evidence on flagged claims
