X is Primary: Two Types of Gravity, Magnetic Genesis, Black Hole Classification, and the Cosmological Constant as Limits of the Trit Master Tensor

The Trit master tensor X_{μν} [1] exists before any decomposition. Its characteristic polynomial yields three invariants: I₁ = Tr(X), I₂ = ½[I₁² − Tr(X²)], and I₃ = det(X). General Relativity is the I₁-only truncation of the full Trit field equation. The decomposition X = S_{μν} + A_{μν} — symmetric plus antisymmetric — is exact algebraically but dynamical physically: the ratio of S to A in any system is determined by the sources, not by the algebra. We prove (Appendix A) that the unique parity-even dimension-6 operator mixing S and A is O = S_{μν}[A^{μα}A^{ν}_{α} − (1/3)η^{μν}Tr(A²)], leading to the Trit master field equation: R_{μν} − ½g_{μν}R = (8πG/c⁴)T^{matter}_{μν} + (1/Λ_c)[A_{μα}A^α_ν − (1/3)g_{μν}Tr(A²)]. GR recovers exactly when W_A = Tr[A²] ≪ Λ_c (verified to W_A/Λ_c < 10^{−25} in all tested systems). The threshold Λ_c = (3/4π)m_p Λ³_{QCD} = 2.36×10¹⁴ g/cm³ is the nuclear saturation density, derived from g_Trit and M_Trit with no free parameters (+2.6%). Two types of gravity follow: Type 1 (W_A ≪ Λ_c, frozen winding, GR exact) and Type 2 (W_A ≥ Λ_c, active magnetic crystallisation of S_{μν}). At det(X) → 0 gravity and electromagnetism become degenerate — Type 3, the black hole singularity resolved as tensor degeneracy. The magnetic genesis mechanism (B primary over E because ∇·B = 0 requires no source on S²) gives jet orthogonality as a geometric theorem from the l=1 spherical harmonic. The cosmological constant Λ_GR is identified as GR's description of I₂^{vacuum} = W_A^{vacuum}/Λ_c — the vacuum antisymmetric winding — using only I₁ language. Because W_A^{vacuum} evolves, Λ is dynamical. The T³ reflection symmetry cancels the bulk QCD condensate; the residual produces evolving dark energy. Four structural predictions are confirmed by DESI BAO 2024 [2]: w₀ > −1, wₐ < 0, dynamical dark energy at 2.6–3.9σ, negligible at z ≳ 1. The cosmological constant problem and the strong CP problem are the same problem: both arise from the antisymmetric sector of X and both are resolved by the T³ reflection symmetry.
