This is the X-B first-order background identity
XB (:variation, :ward).
Off shell the difference is generally the nonzero
equation-ideal representative just displayed.
A general scalar pullback is not asserted to be an
automorphism of the unchanged free Klein–Gordon shell.
No interacting BRST differential or quantum master
equation has been defined.
