Join the current device to the ProLiant without creating a second vault or exposing a dashboard.

Set up this current machine as a Syncthing peer for my existing Obsidian vault. Inspect first; do not overwrite, move, or merge a vault blindly. The local vault path should be /home/aridlin/Documents/obsidian/aridlin. The always-on peer is the ProLiant Syncthing device XZUUCCQ-DIO6LFA-U3QFGQG-BADDUHT-JEOQSVP-ZGHF4NC-RTCEJYI-X55KUAC, sharing folder ID obsidian-aridlin. Ensure Syncthing is installed, enabled for this user, and running. Add the ProLiant as a device using its reachable LAN address when available, share folder obsidian-aridlin with this device, and accept it at the existing vault path only after confirming it is the intended vault. Do not expose the Syncthing GUI publicly. Verify the peer is connected and the folder is idle with zero needed files; report the device ID, folder path, and verification result.
