FA-56391 / Auction allocation rules / Open access
Amendment priority: increase priority · case 01
Increasing requested size keeps its obsolete queue position.
ROOT CAUSE
Increasing requested size keeps its obsolete queue position.
VERIFIED REPAIR
Reset the size priority stamp only for a strict increase.
Unsuccessful approach: The attempted repair uses x["now"] if x["new_total"]>=x["total"] else x["stamp"]; the explicit regression cases demonstrate that this still violates the stipulated auction rule.
Case contract
A single auction order amendment tracks filled units, original queue stamp and an incoming replacement. Price change or size increase loses queue priority; reducing total size cannot erase existing fills. A cancel acknowledgment terminates remaining quantity. Integer stamps and quantities are nonnegative. Named decision increase-priority: Reset the size priority stamp only for a strict increase.

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.
