Abstract

We evaluated condition-normalized ranking for electrocatalytic screening under 12% current-density variation. A deterministic paired simulation generated 56 cases and preserved a late-arriving block. Mean selectivity score changed from 0.575 to 0.613; the paired difference was +0.038 (95% interval +0.036 to +0.040). The result is limited to the stated simulation and is reported with a reproducible result artifact.
