I guess we have to start even more basic. My buddy walks up to a Faraday cage with a magnet and waves it around the outside, not touching the cage. Do you claim that I can't see this on my recordings from EM sensors inside the cage?

You called this a red herring, but it's not. You are claiming a fundamental physical law which prevents information from being kept local and I know of no such principle. You make reference to holography to back this up, but holography says nothing about this -- it is merely 6/

an equivalence of two theories. So if you are going to claim that physics doesn't allow events to be localised, please tell me what this physical principle is. 7/7

You claimed that Faraday cages "cancel EM waves". I keep asking what this is supposed to mean mathematically, and you keep dodging. Do you claim that an EM sensor inside a cage can't detect a lightning bolt hitting the cage from the outside? How about sensor outside, bolt inside?

I answered. The EM field outside (inside) the cage doesn't depend on the charges inside (outside) but only on the boundary conditions set by the cage and the charges outside (inside). If you change the potential set by the cage (eg via lightning bolt), of course the field changes
