Non-imports

The cubic source $J_3$ is not multiplied by ${\sigma }_{\epsilon }$ or by $g$. The metric Cauchy surface stays at $\Sigma =\{t=0\}$. X-E's normalization $-4\mathcal{P}{{\mathsf{E}}_0}^{\mathrm{R}}$ and X-F's three-tree sum are not used. VII-C's hypotheses (E1)–(E4) are not the admission interface; XI-E's Definition of ${\mathcal{F}}_{\mathrm{mc},\mathrm{pol}}$ is. No reflected residue or finite part is subtracted. The empty fixed-input Einstein jet ${\mathcal{J}}_g({\varphi }_m)=\varnothing$ remains XI-A's result XIA. No mixed loop is opened: the cubic source is not contracted against a Hadamard line. No ${\hat{s}}_{\mathrm{int}}$, antibracket, or master identity is built. No $\epsilon \to 0$ limit is taken.
