FA-56641 / Auction allocation rules / Open access
Proxy instructions: bounded next offer · case 01
Proxy steps jump past the authorized ceiling.
ROOT CAUSE
Proxy steps jump past the authorized ceiling.
VERIFIED REPAIR
For bounded next offer, apply the stipulated decision min(x["ceiling"],x["current"]+x["increment"]).
Unsuccessful approach: The attempted repair uses x["ceiling"]; the explicit regression cases demonstrate that this still violates the stipulated auction rule.
Case contract
A bidder authorizes a bounded proxy to submit offers for a specific lot. A proxy instruction specifies a price ceiling, per-step increment, remaining quantity, owner consent and a one-use trigger token. Outputs are actionable submissions, not an optimal bidding strategy. Named decision bounded-next-offer: For bounded next offer, apply the stipulated decision min(x["ceiling"],x["current"]+x["increment"]).

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.
