· 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

Threat numbers in the network's threat bookkeeping are now read from a compile-time packed 32-bit table rather than computed per target, sliding targets are resolved via fixed ray pairs, and delta updates are limited to direct attackers with moved squares and modified ray families per slider. Keeping the network, node evaluations, and move sequences unchanged, the engine is expected to achieve a higher node rate while maintaining bit-identical search outputs.

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.
