I would be curious if there were anything that counts as a formalization of 
causality, and the claim would remain curious.  I cannot speak to the position 
of Causal Set Theory in the question.

It is my impression that causality with respect to physics is some sort of 
philosophical hang-over not necessarily shared by physicists and apparently 
not required of their physics..

 The notion used in relativity has to do with the (necessary) time-ordering of 
somehow-interdependent events although labeling of cause and effect is simply 
about that ordering, with limited conclusions as to their natures (causes can 
be effects and effects can be causes).   Chrysippus might not be very happy, 
and Aristotle even less so.  Agency seems to disappear from the picture, even 
though we might observe/experience such an activity at our level of
