| INSPECT | Choose a duck batch and sample size n. You pull n ducks from the batch and find x defective ones. Uses 1 turn and n budget. |
| SELL POLICY | Estimate a confidence interval [L, U] for a batch's true defect rate. Earn a premium based on interval width, but face a penalty if the true rate falls outside your interval. |
| GOAL | Maximize your total score across all batches within the turn and budget limits. |
