Observation only: the registry fetched public well-known paths and validated the documents against the protocol specifications. No credentials, no message exchange beyond discovery, nothing written.

Produced automatically on every refresh; a new bundle is written only when the observation changes

A trace describes one version on one date. It is evidence of behaviour, never a certification. Dispute it through the agent's dossier; corrections are appended, never overwritten.
