SCALE

The rounding scale of the module's identity: values that round to the same multiple of 1.0 / SCALE compare equal.

Components are stored raw at full Double precision; only identity rounds — equality, hashing, and the module's boolean gates compare components rounded to the nearest 1.0 / SCALE, a quantum of 0.0001 of a unit. Import this constant wherever the quantum is needed — a redeclared copy can drift from the identity it must match.
