Now that promtail.yml relies on ${HOSTNAME:-hermes} substitution, operators deploying on a new host need to know to set hostname: in docker-compose.yml (or rely on the container ID fallback). CLAUDE.md's 'Stack Components' or 'Development Guidelines' section should document that the hostname: field in the promtail service controls the Loki host label, and how to change it for a new deployment.
