Commentary

Rank-15 naive-height record: h=120.642 (beats 127.132). New 3-parameter sub-family of Mestre locus 12*p5=5*p2*p3: six roots = union of two depth-2 cubics with (p-r)(q-s)=0 (equal product), beyond Mestre (u,v) slice. Sextuple {0,7,133,136,430,434}, T=162; base-point injection + Neron-Tate independence (15 indep).
