X-A-ST is cited rather than recounted

The following remain the relational baseline CheungXAST (:edge, :main):

1. the complete second-order coordinate intertwiner;

2. off-shell invariance of the label-smeared relational scalar;

3. covariance of the switched scalar solution with its specified Cauchy data;

4. the strictly negative edge-zone preflight defect,

   $$-{{\int }_0}^{\epsilon }{\sigma }_{\epsilon }^{\prime }(s){\alpha }_{\mathrm{e}}(s)\mathrm{d}s<0$$

   on its named detecting data.

These results are not proved again here. The profile ${\alpha }_{\mathrm{e}}$ in this documentary formula is unrelated to the cone opening ${\alpha }_c$.

In particular, contracting the Noether identity below on a plateau parameter is not presented as a new Route II theorem for that observable.

X-B, X-C, and X-D remain non-inputs of the classical action sheet, as in XI-A CheungXIA. The X-E normalization is not substituted for the one below.
