Thanks for the pointer! Looking at the git-notes documentation, I'd prefer to not use notes if they're tied to commits. (In my case, these objects are private metadata to the git extension I'm writing, so I'd prefer not to attach it to a commit where someone might confuse it with actual repo data.)
Then I noticed this line, which looks promising: It is also permitted for a notes ref to point directly to a tree object So, I'll see if I can do that...thanks! Mick P.S. FWIW...if anyone reads this later and is looking for other examples of tools that store extra stuff in .git/, the git-p4 tool stores its branches in.git/refs/remotes/p4, even though there isn't *really* a remote named p4.
