"""Exhaustive finite-state reproduction of LOGDIFF's exact Boolean calculus.

The paper's Proposition 3.1 is continuous, while Proposition C.3 supplies the
discrete equivalent.  Here atom posteriors are smooth softmax functions of x;
their exact log-gradients play the role of diffusion guidance scores.  Direct
enumeration of the full joint distribution is an independent oracle.
