ResearchAcademicCitationsIntegrityVerification

Verify a bibliography. For every reference: exists, resolves, retracted/corrected/flagged, title/author/year match against the registered record, and a rule-derived fabrication risk — as a signed (Ed25519, RFC 8785 canonical JSON), byte-reproducible JSON report. Input: structured references or BibTeX. No LLM; every claim carries its source and retrieval time. Tier: large, up to 75 references. NOTE: $3.00 exceeds @x402/core's default $1.00 maxAmountPerPayment; raise it (setSpendControls).
