Conservation alone does not identify the source

A restrictive matter model, normalization, and coverage theorem can remove particular ambiguities. Cheung's Oai282-B supplies such a scoped free-scalar stress-class comparison on its independently specified background CheungOai282B (thm:main, def:wardmeaning). It is not a stress extraction for ${\mathcal{P}}_{3q}$, and its Ward conclusions are not Einstein dynamics.
