Its job in the formula

The passage around this formula

The distinction matters formally. Let $A_H(s)$ be the actions proposed by the harness, $A_P(s)$ $\subseteq$ $A_H(s)$ the actions admitted by technical policy, and $A_U(s)$ $\subseteq$ $A_P(s)$ those authorized under the approval process. Tightening approval frequency without reducing $A_P$ leaves a user vulnerable to habituation and mistaken consent. Tightening $A_P$ can prevent an action even when the model or reviewer would approve it.
