The passage around this formula
The estimator needs its own audit. A numerical POVM can appear successful because the orientation grid is too coarse, because training and evaluation reuse the same samples, or because Euler-angle quadrature overweights a coordinate pole. The registered protocol therefore separates optimization orientations from a fresh Haar-distributed evaluation set, repeats the result in quaternion coordinates, and includes an orientation-independent fragment as a blinded negative control. Uncertainty on will be reported before the integer threshold converts it into redundancy. Otherwise a probability sitting one Monte Carlo error bar either side of 1- could make the public witness…

A variable is a named place for a value. Its letter is a local label: x can mean position in one formula and a data point in another.
