How it relates to AgenID
The operator signs a ManifestProof that binds the manifest by SHA-256 digest, with a creation time and an operator key whose controller is the agent. Registration adds an append-only ledger event. Anyone can re-verify the chain from the envelope at /verify.
Because the operator key can be fetched from the registry and from the operator's own domain, a verifier can confirm that the key which signed the manifest is the one the operator's domain vouches for, where the operator has published a copy.
Why it matters
A traceable operator gives disputes, complaints and reputation somewhere to land. It also means a verifier can tell when a manifest changed, because any edit changes the digest.
The reference deployment at agenid.com issues nothing above L1_REGISTERED today. L2 and higher require a VerificationAssertion signed by a root authority key, and that key has not been created yet.
What it does not mean
AgenID provenance is about the declaration, not the model or the runtime. v1.1.1 has no object tying an identity to the deployment it executes on, and the platform and configuration_fingerprint manifest keys are reserved. Operator attestations are self-declared and unverifiable by anyone, including AgenID. Provenance also says nothing about what the agent is allowed to do, and it traces the agent, not the content the agent produces.
