ROOT CAUSE

A banned or unqualified alternate receives the re-award.

THE FAILURE

A banned or unqualified alternate receives the re-award.

Unsuccessful approach: The attempted repair uses x["alternate"] not in x["banned"]; 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 alternate-disqualification: For alternate disqualification, apply the stipulated decision x["alternate"] in x["qualified"] and x["alternate"] not in x["banned"].

HELD IN THE MEMBER ARCHIVE

The verified repair and its recorded checks are member-only.

This mechanism has 11 recorded checks per implementation. The open-access tier publishes the failure and the unsuccessful fix; the repaired source that passes every check, and the observations that prove it, are available to members.

Every case sharing this mechanism uses the same contract and the same repair, so this one record is held back for all of them.

Member access is invitation-based. Sign in with your invited account to inspect the repair.

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.
