Award objection: remedy lot scope · case 01

A successful challenge voids unaffected lots or a rejected challenge voids affected lots.

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

ROOT CAUSE

A successful challenge voids unaffected lots or a rejected challenge voids affected lots.

VERIFIED REPAIR

For remedy lot scope, apply the stipulated decision [i for i in x["awarded"] if i not in x["affected"]] if x["upheld"] else x["awarded"].

Unsuccessful approach: The attempted repair uses [i for i in x["awarded"] if i not in x["affected"]]; 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 remedy-lot-scope: For remedy lot scope, apply the stipulated decision [i for i in x["awarded"] if i not in x["affected"]] if x["upheld"] else x["awarded"].

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.
