Source and exact target

Landmark X-E fixes an Einstein–Hilbert action, a flat gauge-fixed graviton operator, and one scalar-induced retarded tree XE. This manuscript transfers those constructions to the supported presentation retained by X-A-ST, X-C-ST, and the supplied X-D-ST XAST,XCST,XDST.

The action, its normalization, the scalar-sourced tree, and the one-tree defect are attributed to X-E. The proofs below are written on the completion rather than asserted by analogy with the host. In particular, the principal variation, free operator, cubic admission, and nonzero witness are supplied explicitly.

The identifier X-E-ST denotes this proposed source. It is not evidence of repository installation, external registration, submission, acceptance, or independent verification.
