What I mean by reciprocity is, if distant far-field antenna B can transfer energy to our contained-field antenna A, then shouldn't our contained-field antenna A

What I mean by reciprocity is, if distant far-field antenna B can transfer energy to our contained-field antenna A, then shouldn't our contained-field antenna A also be able to transfer energy to the far-field antenna B? Wouldn't that be inconsistent with A not having a far-field emission? If A doesn't produce any field at B, then it doesn't seem possible that the field B produces at A could be absorbed by A. Thermodynamics should guarantee this, otherwise you could use it (in a roundabout way) to violate the second law.
