Missed your response while I was typing mine.

I didn't realize the spin direction was that way, so I guess my theory is off.
The cam jamming was caused by the bolt, which was freed by the wrecked rocker, which was impacted by the valve collision...

So then the first damage was a valve collision caused by the tensioner allowing a slip of the chain? And the hub damage was from the slam to a stop?
