Activity eligibility: round advance · case 01

Replaying a round adds another eligibility-history decision.

ROOT CAUSE

Replaying a round adds another eligibility-history decision.

VERIFIED REPAIR

Append eligibility history only on a newly processed round.

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

Case contract

A stipulated ascending multiround auction records eligibility in activity points. Submitted lots contribute fixed points, withdrawn lots contribute none, a waiver preserves previous eligibility once, and frozen eligibility cannot grow. These rules are pedagogical and independent of real spectrum-auction regulations. Named decision round-advance: Append eligibility history only on a newly processed round.

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.
