B0: the frozen continuation

The sheet is XIV-A's: XII-C's cubic-only $S_{\mathrm{D}}$, inverse ${G_{\mathrm{gr}}}^{\mathrm{R}}=-\mathcal{P}{E}_0^{\mathrm{R}}$ with coefficient $-1$, $g$ and ${\sigma }_{\epsilon }$ fixed and inert, ${\mathfrak{g}}_W={C_c}^{\infty }(W;TM)$ with $\overline{W}\subset P_g\cap \{\epsilon <t<T\}$, the data $(f,g,m,\epsilon ,T,W)$ fixed once and satisfying {(UCP${}_W$)}. The observable is the unchanged antifield-independent lift $\mathcal{O}$. The route is relative symmetry.
