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

Hypothesis

A network of width 768 featuring four king buckets and a multi-layer head (FT x 2 -> 16 -> 32 -> 1), trained for 8 epochs on the v6 dataset (4.93 billion positions), plays stronger on the clock than the previous 768-wide v5 network trained for 16 epochs, and thus stronger than main.

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.
