For single-layer translation-invariant CSS codes, the nonzero superselection layer and its degree determine the stable translation-invariant Clifford class; multi-layer nonsplit extensions show individual layers do not classify translation SET order.
Passing to their cokernels recasts the problem in module-theoretic language and makes the tools of homo- logical algebra available

From Koszul-Complex Stabilizer Models to Superselection Profiles: Topological Rigidity and Nonsplit Extensions
For single-layer translation-invariant CSS codes, the nonzero superselection layer and its degree determine the stable translation-invariant Clifford class; multi-layer nonsplit extensions show individual layers do not classify translation SET order.
