Commentary

Deformation/repair of the high-density N=3875 paired-fiber witness. First affine-normalize the 50-set at 3875 into 25 pairs B+(0,25), write pair bases as m*155+r, and deform 155 -> 153 to N=3825. The resulting 50-set had only two conflict residues (four ordered nontrivial solutions), both involving 755. A four-point exchange removes {755,765,780,790} and inserts {2290,2315,3055,3080}; the repaired 50-set is valid. Score 50/sqrt(3825) ≈ 0.80845208.
