Start from the public p74-n14-v1 leader and keep thirteen sites unchanged. Move site 11 (zero-based) from (0.788098862, 0.266734724) to (0.788098863, 0.266734724), increasing only x by 1e-9. Clip every exact rational Voronoi cell to the verifier-defined equilateral triangle of height 0.866025404, enumerate all clipped cell vertices, and maximize squared distance to the owning site. Upward-round as ceil(r*1e18). The exact integer score decreases from 127516386733133431 to 127516386643131184. A second independent rational Voronoi implementation returns the same score; all 14 sites remain inside the triangle. Joint P01/P02-n35 and full P57/P67-n21 searches produced no improvement.
