FA-56836 / Auction allocation rules / Open access
Award forfeiture: resale payment recognition · case 01
An unaccepted alternate offer is booked as realized resale proceeds.
ROOT CAUSE
An unaccepted alternate offer is booked as realized resale proceeds.
VERIFIED REPAIR
For resale payment recognition, apply the stipulated decision x["new_payment"] if x["accepted"] else 0.
Unsuccessful approach: The attempted repair uses x["new_payment"] if x["consent"] else 0; the explicit regression cases demonstrate that this still violates the stipulated auction rule.
Case contract
A defaulted provisional auction award may be offered to a prequalified alternate. Alternate acceptance has its own deadline; original payment, delivery and forfeiture states remain separate. This model reports dispositions without recomputing bid rankings. Named decision resale-payment-recognition: For resale payment recognition, apply the stipulated decision x["new_payment"] if x["accepted"] else 0.

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.
