Prerequisite sheet

-B and IX-A, non-transfer. VII-B (signature $(+,-,-,-)$) excludes the sharp zero-Cauchy insertion from its stated off-shell microcausal polynomial domain: the adjoint $L^{\ast }a=\theta C^{\ast }b+\delta (t)\mathsf{B}(b{|}_{{\Sigma }_0})$ has timelike conormal wavefront covectors. IX-A (signature $(-,+,+,+)$) admits that same insertion in a different carrier with boundary-trace topology ${\tau }_{\Sigma }$, and proves that unchanged regular approximants do not converge to it in that topology. Neither defines a regulated classical coordinate problem, and neither constructs a quantum product. The regulated kernel of Lemma lem:kernel below is not identified with either sharp object.

prerequisites. V's external $R_{1,1}$, oscillator coefficient, and Newton–wave cubic; II's finite contact matrix; IV's three Hilbert models; VII-E/F and VIII-A–C conical certificates and token promises; IX-Free-2's partial free product; IX-D-v3's conditional subtraction; IX-E-2's $\mathrm{Im}K$ formula; IX-E-3's conditional support bridge. No arrow from those manuscripts into X-A is a theorem.

The relational-coordinate literature BFR,Frob is comparison background only. It does not supply covariance of this switched, regulated prescription.
