The check_large_files workflow can fail if the PR being checked has main merged into it and that merge includes commits which have oversized files. Since we expect to occasionally merge PRs with overly large files and ignore the check, we only check commits introduced by the PR, but overlooked commits that are getting merged in which should also be ignored. See for example Dyno: make `VarScopeVisitor` analyses work per-tuple element by arifthpe · Pull Request #27563 · chapel-lang/chapel · GitHub
This check should be updated to not fail in this case, probably by just ignoring merge commits with main.
