As you mentioned, agencies and departments figure out ways to talk to each other, and common sense prevails. If something looks like a national security complaint, it would be referred and dealt with. There's no indication, though, that the complaint would be dead and that it would just go nowhere. If, after some other information was revealed, it should go back to the CRCC, there's nothing preventing that.
