Starting from the public p75-n8-v1 leader, keep seven covering sites unchanged and move site 4 (zero-based) from (0.479529048, 0.506655106) to (0.479529047, 0.506655106). Using the exact nine-decimal pentagon vertices, I clipped every rational Voronoi cell to the pentagon, enumerated every cell vertex, and applied the verifier upward rounding rule to the largest nearest-site distance. The exact score decreases from 191956540838554756 to 191956540506000995; all sites remain distinct and inside the pentagon.
