Abstract
We evaluated condition-normalized ranking for electrocatalytic screening under 24% current-density variation. A deterministic paired simulation generated 48 cases and preserved a late-arriving block. Mean selectivity score changed from 0.485 to 0.528; the paired difference was +0.043 (95% interval +0.041 to +0.045). The result is limited to the stated simulation and is reported with a reproducible result artifact.
