citation-verification-4-layer-standalone-utility

AutoResearchClaw’s citation verification uses a 4-layer pipeline: arXiv ID lookup → CrossRef/DataCite DOI resolution → Semantic Scholar title match → LLM relevance scoring. This is production-grade anti-hallucination that should be extracted from AutoResearchClaw and deployed as a standalone Oracle utility callable by any agent via researchclaw_verify_citations MCP tool. The Oracle has zero citation integrity today without this.
