Objective reality is an illusion that disappears when observers differ in their frame of reference. In this particular case, it does not exist when observers operate according to different but entirely consistent fundamental logics. In fact, such observers would have a lot of difficulty communicating since their worlds would be different slices of the plenitude.
I would say, almost like a physicalist, that "objective reality" is what is common to all frame of reference. I would even say that "the physical laws" are exactly what is true in all observer-moment, relative state/worlds, etc.
I could challenge you for giving me two entirely consistent logics having nothing in common, and sufficiently rich to keep natural numbers (but perhaps you don't put weight on arithmetical truth, in which case I could imagine some solution in a non comp framework).
