Example. Weight updates and candidate selection are different proxy operators [ftip-007N]
A proxy score can enter a training operator or a selection operator. In the first route it changes the policy; in the second it ranks a finite sample from a policy whose weights remain fixed.
The lifecycle accounting of Definition [ftip-005H] places the first route's rollout and update work in separate coordinates. The second route incurs rollout and evaluation work but no parameter update. Consequently, the event \(\mathcal E_N^{\rm fa}\) in Definition [ftip-007K] concerns the candidate set presented to selection; it is not a claim about the selected output or a training-time policy change.
