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

Hypothesis

Replacing the main network with a 768-wide combination network featuring coarse and fine threat tables, head 16,32, and speed optimizations—per-thread evaluation caches with prefetching, tree-neutral only in the evaluation path, with cache and threat lists reducing the TT Transposition table: a cache of already searched positions, keyed by a hash of the position. at identical hash—yields higher playing strength under clock conditions compared to the baseline, keeping search and time management otherwise identical.

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.
