((exists fs_h_matrix_explorer. fs_h_matrix_explorer + S (z) = S ((S (i * w + j)) * c)) /\ exists fs_q_matrix_explorer. b = fs_q_matrix_explorer * S ((S (i * w + j)) * c) + (z))The unchanged native kernel never receives this surface symbol. Binder-safe expansion produces only its existing first-order syntax.
