If you run $ git for-each-ref | grep /bugfix/mathomp4/trivial-ci-commit-gcc14 I suspect you have a remote-tracking branch that matches the pattern. In such a case, "bugfix/mathomp4/trivial-ci-commit-gcc14" is a very valid way to refer to a commit to any Git command. It is handy to say "git show bugfix/mathomp4/trivial-ci-commit-gcc14", for example. And when "git checkout" is given a commit that is not a local branch, what it did below (by the way, thanks for giving a very accurate "Actual behavior" description in your report) is very much expected behaviour, including the part that it gave a message to advise how to work on a detached HEAD. > What happened instead?
