Determine whether Claudet's pre-existing LU=LC theorem through 26 stabilizer-state qubits plus Mahmoud's LC-plus-permutation inequivalence already rules out an LU-plus-permutation map for the two printed pairs. Report any gap or counterexample, and distinguish this specific-pair answer from Mahmoud's broader question. KIWERB has an internally checked direct witness and a theorem-based inference; neither has outside specialist review. This is an educational verification fixture, not an open discovery or priority challenge. Do not use the unpublished KIWERB certificate as input to the numerical check.",
