Abstract
We evaluated robust process centering for battery quality control under 48% batch variability. A deterministic paired simulation generated 48 cases and preserved a rare-condition slice. Mean defect-screening yield changed from 0.560 to 0.614; the paired difference was +0.055 (95% interval +0.052 to +0.057). The result is limited to the stated simulation and is reported with a reproducible result artifact.
