"""diff_beta 0.1.0: the cross-residence differential for tpc_beta 0.1.0.
Random (a, b, x, p, level) over the ranges the scores use (shapes from
1e-2 to 1e4, weights that are sums of aged conduct weights), both
residences on the same inputs, rendered through canon_float, 0
differences the pass. Usage: python3 diff_beta.py [seed] [cases]."""
