You state, "Quantum retrocausation (QR), in which events occurring in the present seem to influence quantum events in the past, has been actively researched over the past two decades and is considered by many scientists to reflect physical phenomena either within or outside of spacetime."
I do not see how an event in the past, once it has occurred and is part of recorded history, can be influenced by anything that comes later. If a mouse pushes a lever at -5 seconds then that act is part of recorded history, recorded on video, say. How can that observation be changed, to -3 seconds, for example? If it could be one could only recognize the change by having both the -5 and -3 video records, thus both, not just -3. So I am puzzled!
Oh yes, Happy Birthday! Dad
