Worst-powered unchanged cell (push_velocity_y=0.575, foot_friction=0.6, n=100/100) can only detect a 8pp rise. "5 worse" is an honest claim only above that.
Worst-powered cell overall: 19pp (push_velocity_y=0.625, foot_friction=1).
This is empirical evidence under a stated test envelope, not formal verification. Cells outside the envelope were not tested; cells inside it were tested at the stated replicate count and can only detect effects at or above the reported MDE.
