Here are the promised photos.

The pulley had not turned appreciably past the notch, just a tad as part of
the failure but was then stuck in position. The sharp edge where it split
was cutting up belts.
It looks to me that the notch on the shaft may actually have been the
initial failure point, since both pully halves were chewed up by the
notch. (Notice the notch on the good half rounded out a bit). Both
notches were good when installed on the shaft the previous day. It looks
to me like that shaft notch pivoted into the shaft on one end allow the
pulleys to be pulled up over it.
Thoughts?
