Regarding the Committee

Additional spoilers for C;C Wrong-Sider Memoirs and O;N manga I guess

So the actual Committee of 300 is on the topmost world layer, and there exists a fake one in the world layer where the games take place, is that right? The two Nozomi guys for instance think they're a part of the Committee, when they're really not, so that would mean they were deceived into thinking they were. The terminal in C;HN is the actual Committee of 300 from the topmost world layer, right?

In that case, do characters that have connection to the Committee(like Sakuma, Wakui, Kimijima) work for the "real" one? Does this also apply to debuggers like Momose, Gen and Shun? Are they aware of the layered structure of the simulated world they're a part of?
