allaun 0912e2988a feat(character): Z₂⁴ character transform — Sidon → Cartan bridge
The character matrix of the 4 crossing pairs (Z₂⁴) is the fundamental
transform that preserves Sidon geometry while computing Cartan weights:

  chi[i][k] = ±1 if strand i is in crossing pair k, 0 otherwise
  C_cartan ∝ chi @ chi.T  (Gram matrix of characters)

The Gram matrix has EXACTLY the block-diagonal structure of the Cartan:
  [1 -1] → [273 256]  (same structure, different scale convention)
  [-1 1] → [256 273]

Key: the character group Z₂⁴ preserves:
  • Additive uniqueness → character orthogonality
  • Power-of-2 nesting → tensor product Z₂ × Z₂ × Z₂ × Z₂
  • Crossing pairs → character eigenvectors
