ROOT CAUSE

Restricted deposit tranches are available to a new award.

VERIFIED REPAIR

For restricted tranche, apply the stipulated decision max(0,x["cleared"]-x["restricted"]).

Unsuccessful approach: The attempted repair uses max(0,x["cleared"]-x["locked"]); 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 restricted-tranche: For restricted tranche, apply the stipulated decision max(0,x["cleared"]-x["restricted"]).

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.
