Abstract
We evaluated robust process centering for battery quality control under 45% batch variability. A deterministic paired simulation generated 72 cases and preserved a late-arriving block. Mean defect-screening yield changed from 0.541 to 0.595; the paired difference was +0.053 (95% interval +0.051 to +0.056). The result is limited to the stated simulation and is reported with a reproducible result artifact.
