Bid disclosure: alias result view · case 01

Result views expose identity or lose the stable pseudonym needed to follow awards.

ROOT CAUSE

Result views expose identity or lose the stable pseudonym needed to follow awards.

VERIFIED REPAIR

For alias result view, apply the stipulated decision [[x["aliases"].get(r[0],"anonymous"),r[1]] for r in x["records"]].

Unsuccessful approach: The attempted repair uses [["anonymous",r[1]] for r in x["records"]]; 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 alias-result-view: For alias result view, apply the stipulated decision [[x["aliases"].get(r[0],"anonymous"),r[1]] for r in x["records"]].

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.
