Generalized Mestre/Fermigier quartic family from Mestre parameters u=-3, v=-1/2 (canonical primitive roots [0,113,550,753,868,1058]), specialized at T=10239/176. A native M=6000 Nagao rescore selected the curve; quartic rational-point search to bound 2,000,000 plus an integral-x search to 10^12 found and certified 20 independent points.
