Remark: Downstream impact

M.2–M.4, M.7. The numerator relations, the graded presentation and everything built on it use only $c\ne 0$ and the single side $T_1$; they are now unconditional on $\Omega$ (statements that also use Gate V stay relative to that convention). M.6. Theorem thm:M6-S2 gives $r=-2i{\pi }^2{c}^2$; with $c=1/(4{\pi }^2)$, $r=-2i{\pi }^2\cdot \frac{1}{16{\pi }^4}=-\frac{i}{8{\pi }^2}$. The boundary side is $Q-i0$, so the angular integral ${\int }_{S^3}(Q-i0{)}^{-2}\mathrm{d}\sigma =-2i{\pi }^2$ of scaling_anomaly.py is unchanged in sign; the counterfactual $Q+i0$ would conjugate that integral and flip $r$, and it is excluded by Theorem thm:wpA-Sbv. The top-order scale-residue unit of Section sec:wpB is $i{\pi }^2{c}^2=i/(16{\pi }^2)$.
