Award objection: withdrawn hearing removal · case 01

Withdrawn objections continue to occupy the hearing queue.

Verified by executionVariant 1 · 10 checks per implementationDownload source bundle ↓JSON ↗

ROOT CAUSE

Withdrawn objections continue to occupy the hearing queue.

VERIFIED REPAIR

For withdrawn hearing removal, apply the stipulated decision [o for o in x["objections"] if o not in x["withdrawn"]].

Unsuccessful approach: The attempted repair uses [o for o in x["objections"] if o not in x["resolved"]]; 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 Named decision withdrawn-hearing-removal: For withdrawn hearing removal, apply the stipulated decision [o for o in x["objections"] if o not in x["withdrawn"]].

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.
