Remark: Kraus operators are not intrinsic observables
Observable algebras: what commutation actually establishes › The storage algebra is not yet a dynamical spacetime net · lines 1904–1911
Kraus representations are nonunique, and their labels need not be operationally available local records. An algebra generated by arbitrary Kraus representatives requires an additional representation and localization choice. Even exact equality of complete channels does not select equal Kraus lists. A simulator may introduce ancillas and refine histories.
