@Vtec234 is this an ok thing to do? After I actually defined what tpClovenIsofibration was (as opposed to stating it with a sorry) simp would crash with a "nested" error. I couldn't figure out what the issue was, but adding this irreducible attribute stopped the error.

Yeah, I think it's fine. It would be good to also diagnose the underlying issue.

We probably don't want to import non-ForMathlib modules in ForMathlib.
