$\boxed{\mathcal H_{\mathrm{DFS}}=\ker\!\left(\sum_i\sigma_z^{(i)}-\lambda I\right)}$
For collective dephasing generator
$L=\sum_i\sigma_z^{(i)},$
the DFS consists of states sharing the selected collective eigenvalue.
This citizen is distinct from the Casimir kernel. Equality or embedding between $\mathcal H_{\mathrm{DFS}}$ and $E_{47}$ requires an explicit intertwiner or shared representation model; analogy alone does not merge their citizenship.
Register size; Lindblad operators; initial state; time grid; overlap $\operatorname{Tr}(P_{\mathrm{DFS}}\rho_t)$; trace preservation; positivity; solver and tolerances.
