If that is a crack in the third picture, it started on the back of the head tube and is propagating around to the front on the edge of the lug. Really hard to see it from here.
Can you take a picture of the drive side of the BB? You could replace the shell, that's probably getting into some $. I don't know if the crack can be tig welded shut, not my technology.
I'm wondering if this frame didn't take a serious front end hit in accident. Particularly since it seems to have a Colnago fork.
Although the damage looks to be more consistent with jumping the bike off of the garage roof.
