N. Cheung, Landmark XI-B: The free de Donder multiplet for the ramp Einstein–scalar sheet: causal propagators, residual gauge, and the layer dressing. Supplied manuscript XI-B.tex. Used for the free inverse, ghost normalization, plateau class, ramp, and distinction between layer source support and propagated support.

XIE

N. Cheung, Landmark XI-E: On-shell admission of the fixed-width tree, a localized first-order identity, and the held-fixed defect. Supplied manuscript XI-E.tex. Used for the scalar completion, coordinate prescription, polynomial carrier, and distinction between product data and a state.

XIG

N. Cheung, Landmark XI-G: The free-shell class of the cubic Einstein kernel: the onset covector is inherited by every representative. Supplied manuscript XI-G.tex. Used for the closed original obstruction, the class criterion, and comparison with the pure-trace cubic coefficient. Its plane-wave proof is not repeated.
