Abstract
We evaluated condition-normalized ranking for electrocatalytic screening under 34% current-density variation. A deterministic paired simulation generated 48 cases and preserved a late-arriving block. Mean selectivity score changed from 0.478 to 0.519; the paired difference was +0.041 (95% interval +0.039 to +0.044). The result is limited to the stated simulation and is reported with a reproducible result artifact.
