  "description": "A service endorsing autonomous agent runtimes: it appraises hardware-rooted runtime attestation evidence for an autonomous software agent (e.g. TPM quotes appraised into an EAT Attestation Result under the IETF RATS architecture, RFC 9334), verifies the mandate under which the agent is authorised to act, and issues machine-verifiable endorsement attestations (e.g. MachineMandate credentials presented over OpenID for Verifiable Presentations) that cryptographically bind the attested runtime to that mandate. A relying-party verifier accepts such an endorsement only when the issuing service is listed in a trusted list under this service type identifier with service current status 'granted'; a valid signature from an unlisted issuer is not sufficient.",
