Bisect broken. No build bot link in the latest, but the earlier attempt is failing an assertion.

AssertionError

I'm just realizing that this regression is the same for the ref graph. So from an alerts standpoint this is noise. But the assertion/bisect problem is still worth following up on.

Probably bisect is just failing because we changed the benchmark name and it doesn't support that.
