How to separate sensor sensitivity from navigation accuracy
A precise sensor measurement does not by itself establish end-to-end navigation accuracy or low drift.

What a quantum-navigation trial must disclose
A navigation trial needs an environment, reference system, aiding inputs, and an accuracy measure—not only a sensor headline.
