Fields and independent kernel conventions

For the independent kernel results, use

Tensor components and covectors at different points are compared in the fixed Minkowski trivialization. Distributions are paired using the fixed coordinate density. No corresponding identification on a general curved spacetime is assumed.

A future interacting application must specify Einstein–scalar field content together with the ghosts and auxiliary fields of its gauge prescription. Changing the scalar coupling, field parametrization, or gauge complex changes that application.
