A declared geometric subsystem is additional data

What would be needed for a geometric interpretation › A declared geometric subsystem is additional data · lines 1862–1875

Suppose a physical model identifies

B = G \otimes E

and specifies a collection $O_{G}$ of bounded Hermitian observables intended to represent geometric quantities. Define

C_{G} = Tr_{E} C .

This declaration is stronger than merely naming $B$ “geometry.”
