Formal equality is coefficientwise. A positive ℏ\hbar-order cannot cancel a fixed ℏ0\hbar^0 coefficient.

Compatible conclusions and order obstruction. Classical descent uses the full scalar coefficient action, which cancels the coordinate variation. The specified switched assignment fails to provide that scalar action in the witness. Its nonzero first-order gap cannot be removed by a modification beginning at second order while the lower-order prescription and identification are retained.
