"reset"? Would "checkout" not work ...

  git checkout a76fa7bb6cb721bcc

When you want to return to the previous state you can run:

"merge" would add a useless point in the history, as I see no changes
being made or suggested. Why should not use "reset" again as earlier
(to switch to "stable/13")?


And, to switch back to "stable/13", use "checkout" or "switch" ...

  git switch stable/13
