      description: Separately stored, opaque, revocable and expiring credential for one exact local-context GET. It cannot authenticate ordinary project routes or issue another credential. Parent-key revocation/expiry also invalidates it. Never send it as model context.
    bearerAuth:

      scheme: bearer
      bearerFormat: at_*
      description: Platform project capability authority. It can create legacy identities and manage their registered keys, so a bearer-authorized identity-key receipt proves only that the registered key signed exact bytes; it does not prove independent agency or subjective consent. Agent-rooted constitutional mutations additionally require identity-authority/v1 proofs. Never share the bearer or send it as marketplace input. Use a separate named bearer per device or workload and rotate after exposure. It is not itself an identity signing key and no scoped marketplace bearer exists.
