The rational weights finiteN3AbCutoffWeights_48 give an evaluated N₃ coefficient certificate for the anchors oneSmallCutoffRow_48.triple.anchorA and oneSmallCutoffRow_48.triple.anchorB. All weights are nonnegative, every coefficient norm satisfies its prescribed weighted bound, and each row’s total weight, multiplied by 101/100, is strictly less than oneSmallCutoffRow_48.Mn. The coefficients incorporate the integer row divisor.
