CERTavia is an independent technical compliance-evidence methodology developed by Litzki Systems LLC for organizations deploying AI-adjacent systems. It evaluates infrastructure integrity, machine readability, identity consistency, transparency, agentic declarations, and AI governance across 6 clusters — producing a binary verdict of CERTIFIED or FAILED. This is a technical assessment, not a legal opinion and not a conformity assessment under EU AI Act Art. 43.

• 1
  Download the signed attestation document This is the trust basis — the exact bytes that were signed, not a summary computed by our server: GET https://vault.litzki-systems.org/c/4e16d6e5cbab43bb.json
• 2
  Retrieve the Ed25519 public key via DNS The signing key is published in the DNS TXT record of the issuer: dig TXT _sovp.certavia.org
• 3
  Verify the signature with any Ed25519 library Strip integrity_proof from the downloaded document, canonicalize the rest per RFC 8785 (JCS), then Ed25519-verify integrity_proof.signature against it using the DNS-resolved key.
