Git LFS file not shown

You'd better summarize what's changed in Git LFS then. Are these artifacts we've generated by an established process?

I am very happy to see no CI or DCA issues here (aside from a few new dataset check failures possibly). 👍

Yes: https://github.com/github/codeql/blob/main/swift/third_party/resources/updating.md

I looked at the DCA results with Paolo. We believe those dataset check changes are wobble we've seen before, and which is not related to the update.
