I like the new separation.
It would maybe make sense to write explicitly that a "Trigger Event" is an "invocation" event, whereas a "Precondition" represents a "state".
Otherwise, it is pretty clean (in my opinion).

Looks great. I think the caller, trigger event, etc. would also help if added to the core ICSs eventually to better understand the context of all the functions.
