- Replace OBSERVABILITY_DATA_ROOT with per-service *_ROOT variables in docker-compose.observability.yml. - Each service root must contain config/ (mounted read-only) and data/ (mounted read-write), grouping config and state together for Portainer. - Update docs/observability-runbooks.md with the new variables, a setup script that copies repo configs into each service root, and updated backup/restore examples.
