Stack from ghstack (oldest at bottom):

Parse vllm_post_grad.* graph dumps and before_post_grad_graph artifacts

consecutive inductor passes. Each pass diff is output as a .diff.html
file linked from the artifact listing.

We now have this additional section in the tlparse:

diff view w/ the SequenceParallelismPass:
