+1 cage, -1 blade. One hour of cage adjustment turned out to be infinitely superior than one day of blade adjustment. We're getting retroreflection from ETMX.

Cage = controlled push.  Easier to make small steps because the push screw travel is not mechanically amplified. Loosening/tightening dogs don't affect the YAW/PIT by a big amount, so we just moved it until the angle was good, and tightened the dogs and that's it. And no mechanical interference to worry about (even though we checked).

SUS is taking TMSX TF to check if anything is touching. If good, tomorrow the temporary dogs will come out, we need to change the in-air path a bit as as the beam is clipping at the top periscope mirror, we'll tweak the telescope path a bit and move to the IR QPD path.

Success!
