A finite-coordinate reduction of the corrected superposed A #

The operator-norm consumers of Section 3 do not require an almost-sure bound simultaneous over the uncountable unit sphere. Positivity bounds each of the two coarse matrix norms by its trace, and both traces are sums of the 2 * d pure coordinate quadratic forms

((sqrt sigma)\u207b\u00b9 e_j, 0),    (0, sqrt sigma e_j).

The deterministic theorem below records that reduction using CoarseGraining's trace A. The final theorem intersects the corrected superposed conclusion only over j : Fin d, once for each pure leg. It retains the exact scale-separation, wave-envelope, and all-load potential gates; no gate is strengthened and no uncountable intersection is taken.
