The setup screens can reach a database machine by a join code instead of ssh: they listen on 7444 and show a short code; llmgw join dials out, checks the setup by fingerprint, admits itself with the code's secret, and runs what the setup sends until it is done. A joined machine is one more onboard.Remote, so checks and the Patroni install run over it unchanged. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
