FA-57501 / Auction allocation rules / Open access
Result publication: withdrawn result tombstone · case 01
Withdrawn results remain public or appealed results are mistakenly removed.
ROOT CAUSE
Withdrawn results remain public or appealed results are mistakenly removed.
VERIFIED REPAIR
For withdrawn result tombstone, apply the stipulated decision [a for a in x["ids"] if a not in x["withdrawn"]].
Unsuccessful approach: The attempted repair uses [a for a in x["ids"] if a not in x["appealed"]]; 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 Readers request a publication edition; drafts and withdrawn results must not appear. Named decision withdrawn-result-tombstone: For withdrawn result tombstone, apply the stipulated decision [a for a in x["ids"] if a not in x["withdrawn"]].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.
