/**
 * BandExcludedFromFreeze — a band the energy rule wanted frozen and the
 * singular-gauge rule kept out of the freeze, and at how many k-points.
 *
 * It is a fact about the dataset -- the trial orbitals have none of the
 * character the state needs -- and the one thing about a model that should
 * never be silent, so it travels from the classifier to the log and the
 * results file under names rather than as a pair whose order a reader has to
 * look up.
