Bummer indeed. Good luck with the warranty, & don't let the dealer get away with it, I hate it when they do this.
HAZ= Heat Affected Zone for those who were wondering.
If I look at all the pictures the crack does extend beyond the HAZ on the non drive "left" side. My guess is it started from an initiation point in the seatpost relief, followed the HAZ boundary line of least resistance and was/is still growing away from the relief cut to the left.
