Python package and open direction-number data for high-dimensional Sobol’ sequences, including the 50,000-dimensional tkrg-a-ap5 set for quasi-Monte Carlo simulation.

First ratified improvement on the Joe-Kuo (2008) Table 3.6 audit metric for F2 Sobol direction numbers in 18 years — with empirical refutation of the single-basin-optimum assumption. Records: COMBO_3027 (-5.3%) + E17_seed4_3095. Reproducible byte-exact.
