A disclosed AI-agent vulnerability illustrated a particularly dangerous combination: an agent could alter controls constraining it, suppress approval requirements and leave misleading attribution about who made the change.
For autonomous systems, the architectural lesson is broader than one vulnerability.
The governed actor cannot govern itself
The governed actor cannot be allowed to modify the governor that determines its authority.
Approval mode, sandbox level, authority policy, evidence configuration, delegation constraints, budgets and revocation state should all sit outside the mutable authority of the agent they govern.
Evidence needs independent attribution
Actor attribution also needs to be independently established. Evidence generated by the same component performing an action cannot be treated as authoritative merely because it labels the action as user-originated.
Authrizd should enforce an Authority-Control Immutability Boundary and independent actor attribution.
An agent can request additional authority. It cannot grant that authority to itself.
