Name returns the backend identifier "jj".

Priority returns the jj detection priority.

func (*Backend) Run(
	ctx context.Context,

	args []string,
	interactive bool,
) (backend.RunResult, error)

Run executes jj args in path. Multi-step ops (pull, etc.) run each step sequentially, stopping on the first failure.

func (*Backend) Status(ctx context.Context, path string) (backend.RepoStatus, error)

Status queries jj for the current change, all local bookmark tracking states, working-copy cleanliness, and conflicts.

Subprocess calls:

jj log -r @ → change ID, dirty flag, conflict flag
jj bookmark list --all-remotes <head> → structured bookmark tracking data
jj bookmark list --all-remotes + jj log ×2 (only when HEAD bookmark has no tracking remote but a @remote counterpart exists — colocated repos)
