""" verify_P188.py — Numerical consistency checks for P188 (The orthogonal direction H_{U(1)}^⊥ in the centraliser 𝔷 ⊂ 𝔥_{E₆}). Checks: 1. ALPHA_INV = 4π³ + π² + π (TOE constant, sanity) 2. Complement root count |Φ_{E₆} \ Φ_{F₄}| = 24 = 12 positive + 12 negative 3. H_{U(1)} charges: 12 positive complement roots at +1, 12 at -1 (signed) 4. H_{U(1)}^⊥ charge split: 6 positive complement roots at +1 under H_{U(1)}^⊥, 6 at -1 — sum = 0 (encodes the 12/12 split of pos roots) 5. Killing orthogonality K(H_{U(1)}^⊥, H_{U(1)}) = 0 6. Equal Killing norms: K(H_{U(1)}, H_{U(1)}) = K(H_{U(1)}^⊥, H_{U(1)}^⊥) = 24 7. 27-decomposition tracelessness under H_{U(1)}: 26·(+1) + 1·(-26) = 0 8. 27-decomposition tracelessness under H_{U(1)}^⊥: 13·(+1) + 13·(-1) + 1·0 = 0 9. Singlet charge under H_{U(1)}^⊥ = 0 (forced by tracelessness) 10. Differential operator orthogonality on S³: ⟨∂/∂ψ, ∂/∂φ⟩ at a generic point of S³ is sin(χ/2)cos(χ/2) × 0 (the round-metric inner product of the two Killing vectors vanishes: g(∂/∂ψ, ∂/∂φ) = 0 everywhere on S³ in round metric) 11. |∂/∂ψ|² = 1/4 (constant, nowhere-vanishing) 12. |∂/∂φ|² = (1/4)sin²χ (vanishes at χ=0, π — the Hopf poles) 13. The commutator [∂/∂φ, ∂/∂ψ] = 0 as coordinate vector fields 14. Mass-gap estimate: required κ ≫ 1 (Theorem 6.1) 15.
