Receipt feed
Every receipt below is a real dual-signed envelope. Your browser checks both signatures — Ed25519 and ML-DSA-44 — against the published public keys, with no account, no API key and no network. Nothing here says “pass” until your own machine has said it.
Not connected yet — it lights at genesis, when the first production keys are published. Until then this page shows specimens.

Frozen at capture, so the same bytes reach every visitor and any two people can compare results. alg 1 is the only algorithm a schema-1 receipt may carry: ML-DSA-44 and Ed25519, both required, neither substitutable. Two different verdicts appear in each row and they are not the same claim: recorded is a signed field inside the receipt, the attestation verdict it carries about an enclave, and it is simply text until something checks the signature over it. verify is the one your browser computes, and it stays blank until it has.

provenance
Captured 2026-08-08 from pcrzero-signer/vectors/receipt-vectors-v1.json, the signer’s golden vector set, by scripts/build-specimens.mjs.
These are not production receipts. The signatures are real and they verify; the signing keys, the measurements and the document hashes are deterministic test material generated from seeds that are visible in the signer’s source. No production key signed anything on this page. A receipt for a failed measurement is signed exactly as strongly as one for a pass, which is why one of the specimens below records a fail and still verifies.
Only public keys are published here — 2 key sets, each a key id, an ML-DSA-44 public key and an Ed25519 public key. The verifier is the SDK’s own, vendored under src/scripts/receipt/ with its source path and re-vendor command in the header of each file.
