Deposit admission: beneficial owner · case 01

Third-party beneficiary deposits satisfy bidder-owned collateral checks.

ROOT CAUSE

Third-party beneficiary deposits satisfy bidder-owned collateral checks.

VERIFIED REPAIR

For beneficial owner, apply the stipulated decision x["owner"]==x["beneficiary"] and x["owner"] in x["owners"].

Unsuccessful approach: The attempted repair uses x["owner"]==x["beneficiary"]; the explicit regression cases demonstrate that this still violates the stipulated auction rule.

Case contract

Toy bidder deposits consist of cleared, pending and restricted tranches. Deposits are auction-scoped and denomination-specific. Admission capacity is per bidder; a waiver substitutes for a required deposit without turning a pending transfer into cash. Named decision beneficial-owner: For beneficial owner, apply the stipulated decision x["owner"]==x["beneficiary"] and x["owner"] in x["owners"].

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.
