Predeclared model families

For family $0$, projection of ${\Omega }_n$ onto its $\theta$-coordinate gives a nuisance-robust confidence set. It need not be an interval or a singleton. If another physical template interpretation remains compatible, the output must retain that ambiguity.

The guarantee is relative to the predeclared candidate families. An unlisted explanation has not been excluded. Failure of a scalar threshold margin is not automatically equality of complete laws; conversely, an absolute mean difference with changing orientation does not define one common threshold. These cautions parallel En01-B and Oai265-A CheungEn01B,CheungOai265A.
