Award objection: filing deadline · case 01

A filing on the final objection tick loses its remedy.

ROOT CAUSE

A filing on the final objection tick loses its remedy.

VERIFIED REPAIR

For filing deadline, apply the stipulated decision x["filed"]<=x["deadline"].

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

Case contract

A provisional award challenge has bidder standing, grounds, evidence receipt, hearing outcomes and a limited remedy. Filing preserves the award but blocks finality until all admissible objections are resolved. Dates are ticks and list entries retain filing order. Named decision filing-deadline: For filing deadline, apply the stipulated decision x["filed"]<=x["deadline"].

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.
