There's a site with just such a 'takedown', which I've been poring over (over which I have been poring?) -- if we're being snarky, the site looks like it was built on 1998 code, but There Be Data Thar. It also has a page for Janet.

It includes this marvelous footnote: "This is based on the medals we saw General Carter wearing in the episode 'Secrets' (209). It doesn't appear to match the medals being worn in Sam Carter's 'dream' in 'The Devil You Know' (313). However, it would appear that the general is also wearing the wrong style uniform for the period in this episode."

Based on this, I'm entirely discounting the uniform in the flashback/evul vision, and not placing too much reliance on the vision itself.

I figured I could make a good case for Jacob having flown too many desks, but I'd be happier with more thoughts than just mine on the subject.
