So, Wilson was lying in his book when he said that was part of his negative conclusion. But if that's so, it also means that the forgeries were not a set-up job done for discovery by Wilson. That undercuts your conclusion, so you need to check your timeline on this point.

Great observation and one I've been wrestling with. How could he have known something that no one else could have.
Either he's lying or he was in on it from the start. That's why I think this story has legs.
IMHO
My theory, for what it's worth, Is that Wilson knew of the docs before British and American intelligence did. He said so himself, then he backtracked. That's one of Wilsons "lies" so often cited. That he said the docs were obviously forged when there was no way he could have known about them. I say he did know about them.
