autoresearchclaw-4-layer-citation-verification-mechanism
AutoResearchClaw’s citation verification runs four sequential checks: arXiv ID direct match → DOI lookup via CrossRef/DataCite → title fuzzy match via Semantic Scholar → LLM relevance judgment. All four layers must pass for a citation to be marked valid. This is production-grade anti-hallucination infrastructure that can be called standalone on any reference list via researchclaw_verify_citations.
