Paste any GateFrame Decision Provenance Record. This portal independently verifies cryptographic integrity — no trust in GateFrame's servers required. Green means the record is untampered. Red means it was modified after signing.
01 — INDEPENDENT
No vendor trust required
Verification runs against the public Ed25519 key. GateFrame cannot alter a signed record retroactively.
02 — CRYPTOGRAPHIC
SHA-256 + Ed25519
Every DPR is hash-chained and signed. Any modification — even one byte — produces a different hash and breaks the signature.
03 — EXAMINER-FORMAT
Reg B §1002.9 aligned
The verification output maps directly to what OCC, CFPB, and state AG examiners require as defensible AI audit evidence.
Verification Input
PRODUCTION · /agentseal/verify + /sign hash check
Paste the full signed DPR JSON (from /sign or /evidence-pack output)
JSON · signed_dpr field
Public Key (optional — uses GateFrame's published key if empty)
Paste a DPR record and click Verify to check cryptographic integrity.
For Examiners — How to Read This Output
A green "Integrity Verified" result means the SHA-256 hash of the record content matches the hash that was signed with Ed25519 at decision time. No modification — to reason codes, model ID, applicant ID, timestamp, or any other field — is possible without breaking this verification. The verifying public key is published at gateframe-verification.netlify.app/?id=public-key and registered with GateFrame's independent trust anchor. This constitutes tamper-evident, independently verifiable AI decision evidence under US Treasury AI RMF Control 4.2, Reg B §1002.9, and DORA Article 8(1).
