Key facts

A missing manifest is reported as not found, not as “not AI”.
Self-signed credentials can be cryptographically valid without being C2PA Trusted.
Pixel edits should fail asset binding.

C2PA records how media was created or edited in a cryptographically signed manifest. Roma Verify reports present, claim_signature_valid, asset_binding_valid, certificate_valid, and trust_status as separate fields.

If you wanted an “AI detector”, read provenance vs detector first. This page does not promise 100% AI classification.
