Governance over autonomy is the enterprise frame. Authority is the missing control.
Governance is the committee. Authority is the decision that allows or stops an action in time.
Most “AI governance” programs inventory models, write principles, and train staff. Those are necessary and insufficient. They do not sit on the path of a consequential effect. An agent that can already reach a system does not pause for a quarterly review.
Authority is narrower and harder. It asks whether this identity may cause this action on this resource under current policy. If the answer cannot be proven, the action does not proceed. That is not a slogan about ethics. It is a control.
The market language has already shifted from capability (“can they act?”) to authorization (“who allowed it, under what constraints, and can you prove it?”). Hood’s public architecture is the shortest version of that shift: identity, authority, control, evidence.
Principles without an authority decision are literature. Autonomy without an authority decision is inherited power.
