Though the hanger should, and as a practical matter must be aligned with the wheel on (the wheel's the reference), that compensates for, but doesn't actually fix the problem of poor fit. Even on a frame costing a small fraction of this one, I'd expect the hanger to pocket flat, and not move when the wheel is tightened.
While I haven't measured or checked the titanium hanger pocket with tools, visually it looks dead flat...it's CNC machined with impressive precision. The edges look square (90 degrees). I would be completely shocked if the frame itself is the problem.
The aluminum hanger on the other hand has obvious curvature on the mating face, so I suspect it's responsible for all of the gap in the picture.
I may try filling the gap with auto body filler while waiting for the new hanger to arrive...it might save a week of waiting. The only thing is, it might be a pain to scrape that stuff off (although I hear a propane torch can be used to remove it).
