Safely configure and verify a Terminalbox SSH host for the official Codex app.
Configure and verify the official Codex app against a paid Terminalbox pane over key-only SSH. Use when a user wants a persistent Codex development host, needs a safe Terminalbox SSH config entry, is troubleshooting Codex remote-host discovery or login-shell availability, or wants to connect an existing Terminalbox pane in Codex Settings → Connections.
