Local notation convention

For this manuscript, the prepared-source symbols are written

as local aliases for the designated source and correction in the supplied XVI and XII material. This convention does not identify unrelated objects in unprovided manuscripts.

The symbol ${\mathcal{D}}_{\sigma }$ is not the de Donder operator applied to $\sigma$.

We reserve:

• $u_{\mathrm{D}}[\gamma ]$ for a diagonal response;

• $U_D[{\gamma }_1,{\gamma }_2]$ for a polarized response;

• $w_D$ for a prospective compact observable kernel;

• $A_D(\lambda )$ for a prospective class-kernel pairing.

Thus no lowercase $u_D$ is used simultaneously for a response and a class kernel.

The selected XI inverse is

Here ${E_0}^{\mathrm{R}}$ denotes the selected XI scalar Green symbol, also printed ${{\mathsf{E}}_0}^{\mathrm{R}}$ in some supplied passages. This notation convention does not enlarge its proved domain. The coefficient $-1$ is not replaced by $-4$ XIB.

Where the response is defined, the action-equation coefficient has the inherited sign
