Excellent work.
I can't get past the fact that CIA confirmed her employment to Novak. If CIA outs you over the phone to some guy calling in, you are not covert. End of story.
If she were covert, first they wouldn't have confirmed it over the phone. Second, Novak is the one who outed her in print, and Corn revealed that she was supposedly covert. If anyone were going to be prosecuted, it should be those two. The fact that they get a pass tells you all you need to know about the motive for the investigation.
What is there to investigate? First, she's not covert, the CIA gave her up over the pnone. Second, they know who printed the information (Novak, Corn) and they know where the original information came from (Armitage).
An "investigation" when you already know the answers is a hoax.
The fact Armitage also got a pass strikes me as well. Very strange prosecutorial procedure: the three suspects whom the strongest case can be made against become witnesses whose testimony is used against a guy (Libby) fingered by one of them (Corn).
