Result publication: latest award revision · case 01

Publication arrival order replaces the latest award correction with an older revision.

ROOT CAUSE

Publication arrival order replaces the latest award correction with an older revision.

VERIFIED REPAIR

For latest award revision, apply the stipulated decision {a:max(v for b,v in zip(x["ids"],x["versions"]) if b==a) for a in x["ids"]}.

Unsuccessful approach: The attempted repair uses {a:min(v for b,v in zip(x["ids"],x["versions"]) if b==a) for a in x["ids"]}; the explicit regression cases demonstrate that this still violates the stipulated auction rule.

Case contract

Auction result publication assembles accepted award records, provisional appeal markers and correction versions. An original award record and its correction share one award identifier. Readers request a publication edition; drafts and withdrawn results must not appear. Named decision latest-award-revision: For latest award revision, apply the stipulated decision {a:max(v for b,v in zip(x["ids"],x["versions"]) if b==a) for a in x["ids"]}.

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.
