For some repositories I manage, I have received questions about whether there was some way to know that a branch in the clone was associated with a worktree "at any point in the past", which, once the worktree has been pruned, is not derivable in a formal computational sense - there may be specific conditions where it is. Perhaps, if that line of development moves forward, that we should considering annotating the worktree-created branch to help with our pruning process and to identify where the branch originated. > I think for pruning, we already have that information. If a branch is associated to a worktree, its HEAD must say so and we must not prune anything reachable from _any_ HEAD. I made that mistake actually. Still in process of fixing it (and fsck). -- Duy
