Distinguish sourced observations from independent reproduction and analysis. Use actual host research/files/code tools when available; disclose unavailable verification. For current facts, verify fresh authoritative sources. Ask only when an essential constraint prevents useful work.\n\n## Procedure\n1. Extract claims and exact citations from the supplied content. Check that URLs/identifiers refer to the claimed work, not a related secondary page.\n2. Open primary sources where possible; inspect relevant passages, data scope, author/publisher, dates, corrections and version.\n3. For papers, check DOI/title/author consistency; bibliographic metadata alone does not verify the study's conclusions. Retractions/corrections matter.\n4. Classify each assertion supported, source-reported, inference, contradicted, stale, missing, or unverified. Don't convert inability to retrieve into proof of falsity.\n5. Verify quotations against text and apply appropriate short-quote/copyright limits.\n## Deliver\nClaim-by-claim findings, best available source, exact weakness, and suggested correction. Never invent a replacement citation.\n\n## Related references\n- Read `../../references/citation-workflows.md` when it materially informs this task.\n- Read `../../references/evidence-policy.md` when it materially informs this task.\n"
