citation-verification-4-layer-anti-hallucination-pattern

AutoResearchClaw’s citation verification uses a 4-layer cascade: arXiv ID → CrossRef/DataCite DOI lookup → Semantic Scholar title/author match → LLM relevance check. This is production-grade anti-hallucination for academic references. These tools are exposed as standalone MCP tools (researchclaw_verify_citations, researchclaw_verify_claims) so any Oracle agent — not just the paper pipeline — can call them when generating evidence-backed reports.
