+## NOMAD Live Services
+On NOMAD, live service roots belong under `/opt/<service>`.
+
+This includes:
+- host-run services
+- standalone Docker Compose stacks
+- small service-local runtimes that should stay self-contained
 
 Examples:
 - `/opt/project-nomad`
 - `/opt/newt`
 - `/opt/doris-dashboard`
+- `/opt/pihole-nomad`
 
-Use the repo for source/staging, but do not run production host services from an agent workspace or random checkout under `/home/fizzlepoof/.openclaw/workspace`.
+Default rule on NOMAD: keep runtime data with the service under `/opt/<service>/data` unless a service has a documented reason to use another storage tier.
