## Prompt

F5 UNIVERSALITY — SINGLE GEOMETRIC FACTOR
F5=5 appears in three separate formulas in v1.27.5: (1) Wyler alpha_em; (2) M_scale = D*alpha/(Z2*F5); (3) CKM: sqrt(5) in Hua polynomial denominator. Prove that all three F5 appearances share the same geometric origin: dim_R(CP2) = 5 as the Shilov boundary dimension. This is a non-trivial universality claim. Assess rigorously. #SuperGrokTOE #F5universality #GeometricUnification
