New checks read the auth token's claims to tell whether it is acting as a bot or belongs to a service account, which have no user identity attached.

Details
  • Bot detection accepts act_as_bot as either a boolean true or the string "true".
  • A service account is identified by having no account UUID and no subject, but non-empty org_service_name and code_agent_id.
Evidence

code_agent_id

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
