# Single-checkout setup (no isolated worktree). The hard-reset a few lines
# down operates on the maintainer's primary docs checkout — the
# uncommitted-changes guard below is the only thing standing between a stray

# Operate from REPO_ROOT, not SCRIPT_DIR (.dev/). Reason: when the agent
# does `gh pr checkout <stale-PR>` on a branch forked before `.dev/` was
# merged to main, `.dev/` gets unlinked from disk. If the wrapper's cwd
# is `.dev/`, the shell's $PWD becomes a dead inode and every subsequent
# command — including the queue's `gh pr list` — fails with "Unable to
# read current working directory." REPO_ROOT survives any branch switch.
