Put another 25 miles on the bike, took off the crankset, took out the bearing. It looked normal with no evidence of damage. Just in case, packed the bearing with red devil grease and reassembled. It spins with more resistance than before, especially when the crank bolt is tightened to spec. By my back of the envelope estimate, we're talking about power losses of ~2 watt at 90 rpm, so, not a big deal.
