The policy your agent actually enforces.
Each approved rule was probed on its own from one eligible case, then compared with the full policy at every probed state.

Probe states are synthetic variations of case refund-01a. The diff describes behaviour on those states; it is not reviewed test evidence. Stochastic agents: rerun with more repetitions to measure rates at each limit.
