Remark: A check that cannot be performed

With the factor $\delta (a-z)$ and its derivatives present in (eq:Q), $K_8$ is singular along all of $S_{J^{+}}$, including points with $(b-a{)}^2>0$, where $\mathcal{B}(b-a)$ is locally constant. A distribution conormal to $S=\{(b-a{)}^2=0,a=z\}$ in the strict sense is smooth off $S$. The reported “regular conormal representation of upper order $3/2$ on ${\Lambda }_{\mathrm{resp}}$ on the separated chronological patch” Iresponse is therefore compatible with (eq:K8) only under a reading of “separated chronological patch” or of “regular conormal representation” that the record does not reproduce. No inconsistency is asserted and none is excluded; the item is in the successor requirement.
