· Evidence: SPRT Sequential probability ratio test. Games are played until the accumulated evidence reaches one of two bounds; then the test stops.

Hypothesis

A speed-up package increases engine execution speed without changing the search tree. It introduces an exact AVX2 network head with fixed neuron pairing via an identically permuted network, alongside accumulator updates integrated into piece placement through the existing CPU dispatch.

Point estimate with the reported 95-percent half-width, per stage. The dashed line is zero. Estimates from a stopped sequential test are biased by the stopping rule; the interval is nominal.
