While it is generally known that retrocausal models can provide an account of Bell-inequality violations in terms of spacetime-local beables, new models can now explicitly show how this comes about. By analyzing a simple local-beable model that precisely recovers the quantum joint probabilities for measurements on a Bell state, general concerns about retrocausal models can be analyzed at a much deeper level than previously possible. (Including questions of locality, fine-tuning, free-settings, etc.) While I certainly have not covered all possible concerns, it will be interested to see whether other general concerns actually apply to this specific model, instead of mere straw-man alternatives.
