pub fn compare_grades(
registered: &MappedGrade,
candidate: &MappedGrade,
) -> GradeComparisonExpand description

the registry accepted.
NotComparable is not “unknown, try anyway”: submitting on a cross-scale difference would ask
the registry to replace a pass with a number, or the other way round, on a guess.
