Autonomy is not one setting
An agent can gather information, propose a decision, prepare an action, execute it, and verify the outcome. Those are distinct authorities, and each deserves a boundary suited to its consequences.
Approval can improve the system
A good approval step is not a panic button. It packages context, alternatives, evidence, and expected impact so that human judgment is faster and better informed. The approval surface becomes part of the architecture.
Provenance makes memory useful
Durable memory is valuable only when the system can explain where important context came from, how it changed, and who accepted the decision. Provenance turns stored text into accountable operating knowledge.
