(** FLOWER-E8-EMBEDDING — E8 = H4 + φ·H4 Decomposition *)
(*
* Formal proof of Dechant (2016) theorem: E8 Lie algebra
* decomposes into two H4 Coxeter subalgebras, one scaled by φ.
*
* Reference:
* - Dechant, P.-P., "The E8 root system from the icosahedron",
* Proc. R. Soc. A 472 (2016) 508-520
* - E8LieAlgebra.t27 (computational verification)
*
* Key insight:
* - H4 is the symmetry group of the 600-cell (120 vertices)
* - E8 roots partition into: H4 roots ∪ φ·H4 roots
* - φ scaling factor preserves the 240-root structure
* - dim(H4) = 120; 2·dim(H4) = 240 = |E8 roots|
*
* Trinity connection: φ² + φ⁻² = 3 encodes this decomposition
* as the dimensionality matching condition.
