The precise Tomiyama input for the operator-field mean
Tomiyama, On the projection of norm one in W-algebras*, Proceedings of the Japan Academy 33 (1957), 608–612, Theorem 1(2), pp. 608–609, DOI 10.3792/pja/1195524885.
Only the bimodule conclusion for the constant-field inclusion is retained.
The contractive retraction and its adjoint preservation are constructed in
OperatorCoefficientMean and OperatorMeanStar, not assumed here.
