The results of the laws are indeterministic, but laws themselves are kinda not—you always get the same probabilities. So I figured you would need additional complexity to distinguish between deterministic and indeterministic parts of description of the universe
Under subjective interpretations like rQM, there arent deterministic and indeteministic parts of the universe. You can use Schrödinger’s equation to model a part of the universe , and that will work until it stops being isolated—until it interacts with something not in the model. All models are ultimately indeteministic because they are always based on incomplete information. And the process by which this becomes apparent, by which the limited model is invalidated, isn’t anything special .
Observer 01 can model system A just fine until it interacts with system B, which they don’t know anything about. If observer O2 is more knowledgeable , they might be able to model the AB interaction using the SWE.
