The response fiber map, b , g , and the advanced operator

${\mathsf{P}}^L{}_M$ is XIV-I's constant map in (eq:T), used and not defined in the record Iresponse; ${\mathfrak{b}}_L$ likewise; $g$ in (eq:K9) is, by XIV-J's Hessian display, “the switch” Jhessian, a role without a displayed formula. The operator ${E^{\mathrm{A}}}_m$ in $F={E^{\mathrm{A}}}_{m}f$ is not declared in any XIV sheet to be the advanced inverse of $\square +m^2$; XII-D sets $v_f=E^{\mathrm{A}}f$ without a display of $E^{\mathrm{A}}$ XIIDweight.
