We present a tensor-network graphical formalism capturing the logical action and error-correcting capabilities of any Clifford circuit with Pauli measurements, and showcase it on new Floquet codes derived from topological subsystem codes, the XYZ ruby codes, which are in the same topological phase as the 2+1D color code and apply a Z3 automorphism to the logical Pauli group every three timesteps, with circuit-level thresholds of ~0.18%.
