CoordExists(
    units_from: tuple | None[<class ’tuple, None] = None,
)-> None

Candidacy predicate for a patch-local coordinate selection.

The bounds are resolved per patch at load, so the index can only ask that the coordinate exist. units_from carries the original range when one of its bounds is a quantity: a metre window still has to exclude a seconds coordinate, or metadata would claim a row that raises UnitError on load.
