Theorem

Let $V=\mathbb C^5\otimes\mathbb C^5\otimes\mathbb C^5$ and let $U_\sigma$ permute tensor factors for $\sigma\in S_3$. With $L=L_{C_5}\oplus L_{C_5}\oplus L_{C_5}$, total-spin Casimir $C$, and E47 projector $P_{47}$,

$$ [L,U_\sigma]=[C,U_\sigma]=[P_{47},U_\sigma]=0. $$

The lattice and E47 sectors therefore share one exact six-element symmetry representation on the common 125-state carrier.

The citizen certifies the simultaneous $S_3$ action. The separately registered 15 layer turns retain their own permutation, defect, and energy-conjugation certificates.
