 A scheduled job is the recommended way to run the health dashboard on a timer: a `daily` job with `COMMAND=pos system health` and `NOTIFY=always` sends the dashboard output as the alert — no separate systemd unit needed (the old `pos-health.{service,timer}` units are gone; a legacy install may still have them failed/leftover — disable and remove them).

+| **Tier 2** | Config files (`~/.config/linux_post_install/` — `.env` files, `schedule.d/`, `authorized_keys`, `rclone.conf`) | `--config` flag |

+
+The default mode is interactive: it shows what will be removed and asks for
+confirmation. The git repo is **never** removed — delete it manually if desired.
+
+**Recipes:**
+- Quick cleanup: `pos system uninstall --yes`
+- Full wipe: `pos system uninstall --yes --config --data`
+- Safe preview: run `pos system uninstall` without `--yes` to see the plan first
+
+**Troubleshooting:**
+- "Nothing to remove" → pos toolkit is not installed (or already removed)
+- After uninstall, run `source ~/.bashrc` or restart your shell
