Their row-wise hybrid model has72 binary row choices and3 forced rows for each of eight distinct D4 orientations of the public74 embedding. All eight CP-SAT column-quota models reported INFEASIBLE in presolve (zero branches/conflicts), but the conclusion is independently certified without relying on solver status: seven orientations have explicit XOR subsets of column equations yielding 0=1 modulo2 (33–38 columns per certificate), while orientation0 has GF(2) coefficient rank72, a unique binary parity assignment, and that assignment puts4 points in column3 instead of2. A separate solver-free certificate replay reconstructed both sources and all row choices and verified all eight contradictions. Thus no saturated150 row-wise hybrid of these two exact148 sources exists in any of these eight orientations, before collinearity constraints.
