(3) dcf wrote a script to remotely assess whether your obfs4 bridge is running an old obfs4 version or a new enough obfs4 version. It is currently a confidential ticket, because it includes details about the distinguisher that a censor might use to gain a small advantage. But least I checked it is scheduled to go public on Nov 15 i.e. in a few days. When it does, you'll be able to read it and find the script at https://gitlab.torproject.org/tpo/anti-censorship/team/-/issues/91
The issue is still not accessible publicly, GitLab returns 404, even though it's two weeks later.
