description: "Hash-chains an identity-verification (IDV/KYC) session's declared results into a tamper-evident session receipt, per attempt: session metadata (verifier identity + version, timestamp), capture-chain attestation (C2PA manifest digest if present), injection-detection verdict, liveness verdict, document-check digest, and device-signal summary. Every verifier-sourced field is labeled asserted: this kernel attests the session record as declared, not detection quality or subject genuineness. Zero PII by construction: consumes only digests, booleans, and scores, and rejects any raw-data-shaped input (images, biometric templates) before compute proceeds."
