special_case_of → generalized_haah pending

The canonical entry fixes the qubit CSS polynomial pair 1+x+y+z and 1+xy+yz+zx. Generalized Haah codes alter the local polynomial data or coefficient field; they contain this choice as a specialization but are not aliases of every periodic Code 1 instance. The target entry is pending.

dual_of → fractal_symmetry_model pending

Ungauging the cubic code produces a spin model with fractal subsystem symmetries, while gauging reverses the dictionary under the assumptions of the construction. This is a representation-changing duality, not a finite-depth logical gate on the same periodic Hilbert space. The target entry is pending.
