Delivery acceptance: payout payment cap · case 01
Seller receives proceeds for unaccepted delivery units.
ROOT CAUSE
Seller receives proceeds for unaccepted delivery units.
VERIFIED REPAIR
For payout payment cap, apply the stipulated decision min(x["paid"],max(0,min(x["delivered"],x["inspected"])-x["rejected"])*x["unit_price"]).
Unsuccessful approach: The attempted repair uses min(x["paid"],x["delivered"]*x["unit_price"]); the explicit regression cases demonstrate that this still violates the stipulated auction rule.
Case contract
Award fulfillment tracks delivered, inspected, rejected and accepted units. Title and seller payout require acceptance, not shipping. Partial shipments and certificates refer to individual auction lot identifiers; freight and storage are fixed integer credits. Named decision payout-payment-cap: For payout payment cap, apply the stipulated decision min(x["paid"],max(0,min(x["delivered"],x["inspected"])-x["rejected"])*x["unit_price"]).

Verification & scope
Stipulated toy auction rules, not a venue specification, financial advice, optimization claim, or live trading implementation. Nonnegative integer inputs and internally aligned list fields only. This reproducer isolates one failure mechanism. Results cover the supplied fixtures. Variants within a family share a test contract and should remain grouped when constructing evaluation splits. Related mechanisms with a shared evaluation_group must also remain together; these controlled models are not independent production incidents.
