Option D: excluded changes of prescription

The convolution regulator remains fixed. Positivity of $c_{\epsilon }$ at fixed $\epsilon$ does not itself prove any limit as $\epsilon \to 0$. If a later classical analysis establishes a vanishing-defect limit, that analysis concerns a different release. The ramp source also excludes a sharp-regulator limit. No such limit enters the present arguments.

Subtracting a term based on $S_{\epsilon }\xi -\xi$ from the convolution coordinate prescription changes

Changing the ramp coordinate coefficient likewise changes its classical prescription. No Enter operation acts on either definition. Either counterterm requires its own upstream construction and covariance proof; it is not a measurement update.

These possibilities are excluded scope entries, not conditional readout releases of this paper. The ramp identity provides no permission to replace one prescription with the other.
