Bid disclosure: auditor linkage · case 01
Closing the auction releases private bidder-alias linkage.
ROOT CAUSE
Closing the auction releases private bidder-alias linkage.
VERIFIED REPAIR
For auditor linkage, apply the stipulated decision x["aliases"] if x["auditor"] else {}.
Unsuccessful approach: The attempted repair uses x["aliases"] if x["closed"] else {}; the explicit regression cases demonstrate that this still violates the stipulated auction rule.
Case contract
Toy auction disclosure views distinguish bidder self-view, public preclose statistics, anonymized postclose results, and auditor-only linkage. List records have fields [bidder, quantity, value]; suppression thresholds count distinct bidders, not submitted records. Named decision auditor-linkage: For auditor linkage, apply the stipulated decision x["aliases"] if x["auditor"] else {}.

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.
