Note: switching to '475bb981990aa175c903ad462127c7d0d62e2354'.

You are in 'detached HEAD' state. You can look around, make experimental
changes and commit them, and you can discard any commits you make in this
state without impacting any branches by switching back to a branch.

If you want to create a new branch to retain commits you create, you may
do so (now or later) by using -c with the switch command. Example:

  git switch -c <new-branch-name>

Or undo this operation with:

  git switch -

Turn off this advice by setting config variable advice.detachedHead to false

HEAD is now at 475bb98 fix: address bot reviews with asyncio task holding and mlflow client optimizations

    # On PR builds, skip the Sphinx build when the PR doesn't touch any
    # files that affect documentation output. Reduces queue pressure on
    # the shared RTD build slots when several PRs are open at once.
    # Tag/branch builds (master, stable, etc.) always run.
    # See https://docs.readthedocs.com/platform/stable/guides/build/skip-build.html

    # Some constructs are avoided deliberately because RTD's job runner
    # silently drops scripts that contain them: use echo (not printf
    # with a backslash-escape format string), avoid backslash escapes
    # in general, and keep shell comments out of this block so that
    # backticks/$() inside comments don't confuse the preprocessor.
