## How do your models relate to the de Broglie–Bohm/pilot wave formulation of quantum mechanics?

Our proof of the violation of the CHSH inequality for our model works in much the same way as it does for other standard deterministic and nonlocal interpretations of quantum mechanics, such as the de Broglie–Bohm (otherwise known as the pilot wave or causal) interpretation. However, in our particular case, this nonlocality does not emerge from the propagation of a pilot wave or similar structure, but rather results from the structure of the multiway causal graph (since it allows for the existence of causal connections between branchlike-local microstates in the multiway system, which may or may not be spacelike-local).
