product_of → hgp
The family fixes the symmetric HGP specialization HGP(H,H) and then restricts H to biregular Tanner factors satisfying two-sided small-set expansion. The constructor regression compares every exported CSS row literally with qeclib.constructions.hgp; generic HGP codes need not meet the expansion hypotheses and are not aliases of this family.
