Outline of an Experiment to Test Retrocausal Versus Superluminal Interpretations of a Digital Protocol Over a Quantum Channel

Abstract
There is an interpretation of Quantum Mechanics gaining ground that had its roots in Feynman-Wheeler absorber theory, which has lead to the Watanabe Two-state vector /Cramer Transactional-Interpretation/ /Sutherland viewpoint of Retrocausality. It seems that fantastical notions of superluminal effects are to be abhorred for equally fantastical notions of retrocausality. Noting that physics is the science of natural philosophy, we add to the argument with an outline of an experiment to settle the matter, by a blocking protocol where future actions would be limited by actions in the past (and hence the future) or not at all if the hypothesis is false.
