Simultaneous fixed-checkpoint assessment

Twenty recurrent steps are one example computation, not twenty independent correctness trials. For unequal sample sizes, use a separate radius and confidence allocation for each mean.

For a paired contrast $D_i$ in an interval of length $B$, the analogous radius is

for $L$ predeclared contrasts. A checkpoint accuracy difference has $B=2$. A difference of two clean-to-probe gaps, represented by four correctness indicators on coupled latent blocks, has $B=4$.

Pairing needs a declared coupling. Different, independently generated probe datasets are not automatically paired merely because they have equal sizes.
