Independent verification
Check a receipt. No account required.
Paste a receipt from Agentic Engineering Platform or open its JSON file. Your browser checks the signature locally, confirms the signing key is one LockedIn Harness publishes, and only then shows the recorded counts, acceptances and source references.
A valid signature only shows the receipt is unchanged since its key signed it. It is attributed to LockedIn Harness when that key is one published below. Review the underlying source evidence before accepting the claim.
Shared exports
How to verify a shared export
Status decks, governance-trail segments, project traceability exports and accepted agent changes can each be exported with a receipt file. Open it here, or paste its contents. The verifier recomputes the signing key's fingerprint from the receipt and compares it with the keys this deployment publishes; whatever the receipt says about its own issuer is not taken into account.
The current receipt key is eng-receipt-43f0337f5326, with fingerprint 43f0337f53269ba233009039d29cb5788e15e07de4886158e21983a208d3dcc6. The same list is published at /.well-known/receipt-keys.json for anyone who wants to pin it.
The governed-receipt/v1 format uses Ed25519 over a canonical JSON body, so the same check can be repeated with any Ed25519 library.
