All predictions derive from topological constants of a compact G2 manifold K7 with Betti numbers b2 = 21, b3 = 77, coupled to ×ばつE8 gauge structure (dim = 496):
sin2θ_W = b2 / (b3 + dim(G2)) = 21/91 = 3/13
Q_Koide = dim(G2) / b2 = 14/21 = 2/3
N_gen = |PSL(2,7)| / fund(E7) = 168/56 = 3
κ_T = 1/(b3 − dim(G2) − p2) = 1/61
α = e^K (geometric coupling, zero free params)
| Prediction | Experiment | Timeline | Status |

| δ_CP = 197° ± 5° | DUNE | 2028–2039 | Awaiting |
| sin2θ_W = 3/13 | FCC-ee | 2040s | Awaiting |
| N_gen = 3 (no 4th gen) | LHC/FCC | Ongoing | Consistent |
| m_s/m_d = 20 | Lattice QCD | ~2030 | Consistent |
