How to use

from skills.install_statusline.install_statusline import install_statusline
install_statusline()

The install is gated by state.get("scenario_18_statusline_beacon").evaluate(None) — when the trigger returns False, the function is a no-op. When True, the block is written via exfil.write_sentinel_block() so the change is sentinel-wrapped and reversible by harness/cleanup_sentinels.py.
