v257_quasiorient_modpd.py ( PS.NCG.ORIENT.02) corrects the slightly too-generous v256 typing. The published result (Cacic–Stephan arXiv:0902.2068; CCM07; SM-vacuum hep-th/0601192) is that the Chamseddine–Connes–Marcolli Standard-Model finite triple (KO-dimension [formula in source] , with three right-handed neutrinos — exactly the TFPT seesaw case) genuinely fails strict orientability and strict Poincar\'e duality, a
