We present the Master Equation, a generalisation of Einstein's field equations derived from a 12-dimensional Riemannian manifold M₁₂ = (S¹ S³) K₈, where K₈ = (CP² S²) w (T²/Z₂) ^Spinᶜ. The internal eight-manifold K₈ does not admit a spin structure; the topological obstruction w₂ 0 inherited from CP² forces a Spinᶜ structure whose determinant line bundle L = O (3) carries a quarter-period holonomy e^i/2. This single geometric mechanism determines the electroweak mixing angle, fermion generation count, quark flavour structure, and the gravitational hierarchy. The 4D reduced field equation is G_ = 8 G₄₅₅ T_ + 12__ + ₄₅₅g_, where Q = (-) ² is the Quantum Coherence Dilaton (= consciousness coherence field;, = quantum/anti-quantum spinor condensates) and = 12 is the topologically derived quantum coherence coupling constant. The framework derives, with zero free parameters, from the single topological integer (K₈) = 12: the Weinberg angle ²W = 0. 224 (observed 0. 231, 3%) ; exactly three fermion generations via Dolbeault cohomology h^0, 2 (CP², O (-4) ) = 3; the Planck–weak hierarchy e^12 2. 3 10^16; and CKM matrix elements |Vₔₒ| = 0. 225 (0. 1%), ₂ = 65. 6° (0. 6%), |V₂₁| = 0. 044 (5. 3%, derived from (S²) = 2 fibre sector correction). All predictions are falsifiable: a fourth fermion generation, a Weinberg angle deviating by more than 10%, or CKM elements inconsistent after renormalisation group evolution would each independently invalidate the framework.
