From the N=3875 high-density seed. Normalize its exact +150 pairing by multiplying by 6^{-1}, extract the 25-point exact core in (Z/25)^2, rotate coordinates so the vertical span is 14, then tensor with the integer genus-one witness {0,1,6,7,15}. This gives a 125-point stable family for q>=1557; here q=1562.
