Input statement: XII-D: completed insertion

The insertion is ${\mathcal{C}}_{3,\mathrm{D}}={\mathcal{A}}_1[u_{\mathrm{D}};\varphi ]$, with both legs retained. Its compact collar root and compact polarized kernel are constructed, $\mathrm{WF}(t_{\mathrm{D}})\subset Z_3$, and $Q_H{\mathcal{C}}_{3,\mathrm{D}}\in {\mathcal{E}}_H$. The sign $L{u}_{\mathrm{D}}={\mathcal{J}}_{\mathrm{D}}$ differs from the action-coefficient sign $L{r}_{\mathrm{D}}=-{\mathcal{J}}_{\mathrm{D}}$ XIID.
