The tech did fine (sorry I can't remember his name). He jacked the bike up, spun the wheel like 50 times, listening, feeling, and playing with the brake lever.
He came over and discussed it with me for a while, suggested that it might work itself out, and even offered to order a couple of rotors. I declined, but said I would be back if it didn't clear up within a few thousand miles. Hopefully it will clear up, but if it continues I will be back to see you.
