# bind-exo-node.sh — make THIS Mac Studio a permanent exo cluster node.
# Portable: uses $HOME + the local user, so it works on any studio
# (macstudio3 / stevestudio2 / steveabramsdesignsgmail.com / etc).
# Run it ON the node you want to bind. Idempotent — safe to re-run.
#
#   Steve's rule: the exo cluster is ALWAYS on. This installs a launchd
#   KeepAlive agent so exo (master+worker, API :52415) survives crash/logout/reboot
#   and auto-joins the LAN cluster via exo's zero-config peer discovery.
