In short: I don’t know where, but I do know that it’s in there. My logic is that I’ve used tools that viz what you’re talking about. They actually have much prettier versions of the (admittedly very nice, thank you) drawing you made. Bitbucket has one. These viz would be impossible to make without the info. I read the git manual a couple of years ago. (All except the plumbing chapters.) There are commands that unveil deeper and deeper into whatever you’re querying, and it was in there somewhere. Give it a look. It’s a very nice manual. I read the whole thing (minus the plumbing) in less than 4 hours. If I had to guess, I would say git reflog is involved.
