Peer review was instructive more than adversarial. Referees asked for more stringent controls: could the phase be explained by thermal gradients along the piezo actuators? Were there electromagnetic cross-couplings? Mira and the team performed focused tests. They added thermal shields, redundant temperature sensors, and blind randomized cycles. Each round of scrutiny reduced the space of plausible conventional causes, strengthening the geometric interpretation. hmdscience.com physics
