Note: switching to 'cb8a51f50036cd17555c3266a997dd4155c58c5a'.

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 cb8a51f fix: resolve semaphore logic, update callback signature, and align constructor with tests

    # 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.
    # The guard matches doc/ but excludes doc/.claude/ (Claude Code skills
    # and agent files), which never participate in the Sphinx build, so a
    # PR that changes only those paths skips the build instead of running one.
    # 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.
    # The runner also strips the surrounding single quotes from arguments,
    # so use git's :! exclude shorthand rather than :(exclude): unquoted
    # parentheses reach /bin/sh (dash) and abort the script with a syntax error.
