FA-57276 / Auction allocation rules / Open access
Tie ballot: publication before award · case 01
Unpublished ballot outcomes or too many winners become awards.
ROOT CAUSE
Unpublished ballot outcomes or too many winners become awards.
VERIFIED REPAIR
For publication before award, apply the stipulated decision x["committed"][:x["supply"]] if x["published"] else [].
Unsuccessful approach: The attempted repair uses x["committed"] if x["published"] else []; the explicit regression cases demonstrate that this still violates the stipulated auction rule.
Case contract
A toy tied-award ballot has a frozen eligible bidder roster, published ticket order, one ticket per eligible bidder, and an explicitly supplied draw index. It is deterministic: no randomness claim. Declined winners rotate to the next eligible ticket without returning the declined bidder to the draw. Named decision publication-before-award: For publication before award, apply the stipulated decision x["committed"][:x["supply"]] if x["published"] 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.
Observations recorded using Python 3.12.14 at 2026-09-29T14:46:15.062423+00:00.
