7-adic fiber lift from the high-density N=301 record. After unit-normalizing the seed's seven translated pairs one gets the exact core C={(2,4),(3,1),(3,2),(4,1),(4,4),(6,0),(6,2)} in (Z/7)^2. Lift C by itself to 49 points in (Z/49)^2 and use a boundary-optimized horizontal shear (low (1,0), high (2,3)); embedding at q=119 gives this set modulo 49*119.
