A fixed density ramp can fail the harmonic response test

The transition witness does not contradict X-A's reported plateau-supported classical intertwiner through second order CheungXA. It also does not reproduce the distinct convolution obstruction of X-A-conv.

A correction beginning at second perturbative order cannot change the first coefficient in (eq:ramp-defect). Likewise, in $E[[\hslash ]]$, a nonzero $D_0\in E$ cannot be cancelled by an element of $\hslash E[[\hslash ]]$, because the constant coefficient remains $D_0$. Neither statement is a quantum Ward calculation.
