Frame and fork came in yesterday. Both look to be pristine and brand new. The seller forgot to include the headset, seatpost clamp, and derailleur hangar, so they'll arrive next week.
The positive news is that I was able to weigh the frame by itself without any embellishment - 1.370kg (for a 54cm), according to my luggage scale. The fork, uncut, is 570g, though I'd expect it would drop to about ~500g (if not a bit less) once I trim it down - no intention of riding with four inches of steerer tube showing.
As reference, the frame was advertised as 2 lbs, 11oz - about 1.220kg, so just a tiny bit disappointed that the number wasn't closer to that, but regardless - it's still a reasonably light aluminium frame that I picked up pretty cheaply, and I've wanted to try a CAAD for a while. And the fun will be in the building!
