$\boxed{\mathcal R=\mathcal R(C,P_K,\Phi,\Gamma)}$
A composite invariant assembling the Casimir carrier, kernel projector, compression map, and recursive stabilizer into a single executable transformation law.
This citizen is distinct from $E_{47}$: $E_{47}$ supplies an invariant sector, while $\mathcal R$ is a composite operation defined on or through that sector.
Expected certificate fields: operator domains and codomains; explicit composition order; projector residual; fixed-point residual; software versions; input hashes; output hashes.
Canonical source extraction and version-locked executable package.
