REQUIRED for any VCS operation in jj repositories (`.jj/` directory present). Activate on: commit, push, pull, status, diff, log, branch/bookmark, PR, merge, rebase, stash, conflict, undo, or any version-control task. In jj repos, use jj exclusively — running git commands can corrupt or confuse state.
