I beg your pardon!, I'm not understanding the answer, what is it that might be specific of Redex?
I suspect that the answer is that there isn't some recent work on formal semantics specifically about Redex. In that case, does anybody know if the already mentioned paper  is still a good match for today's semantics of Redex? The paper provides a mechanization of the model in Redex, together with some tools to test it. Of interest is a tool that asks Redex to generate random patterns and terms that match against them, and tests if the mechanized model is capable of reproducing the matching (or that is what I suspect that the tests are doing :P ). It was possible to run the mechanization on a recent version of Redex, but the generated patterns are ill-formed (e.g., in-hole p1 p2, where p1 contains more than 1 hole). Of course I could provide more details about the error, but I don't know if it is of interest, it's a mechanization written for the Redex version that comes with Racket 5.* or something like that.
