Signed verification certificate

$249 once

For an AI governance, procurement, or platform assurance lead: one signed HTML and JSON verification certificate generated from an agreed evidence scope, delivered within two business days after we receive that scope.

Cancellation: Cancel before generation begins. If we cannot agree on a bounded evidence scope, nothing is billed.

What you receive

canonical JSON describing the agreed claim and source digests;
a detached Ed25519 signature and public key;
a human-readable HTML certificate and a local verification helper;
explicit limitations—what the signature does and does not prove.

This is an integrity certificate for evidence you provide or authorize us to inspect. It is not a legal, security, or compliance opinion.
