+Re-run the installer so it registers the bundle through GNOME's extension

+curl -fsSL https://git.ssh.surf/snxraven/gnome-jarvis/raw/branch/main/packaging/web-installer.sh | bash -s -- --enable

+Then confirm `metadata.json` has UUID `[email protected]` and run:
 
 ```bash
 gnome-extensions enable [email protected]
 journalctl --user -b | grep -i jarvis

+installer; it records the Node executable found in the installing user's PATH
+when it writes the user service. Check the result with:
+
+```bash
+systemctl --user cat jarvisd.service | grep ExecStart
+command -v node

 ## The daemon restarts
 
 Inspect `journalctl --user -u jarvisd.service`. Common causes are Node version,
