+## Host-Run Services
+If something on NOMAD is not deployed as a Docker compose stack, its live runtime belongs under `/opt/<service>`.
+
+Examples:
+- `/opt/project-nomad`
+- `/opt/newt`
+- `/opt/doris-dashboard`
+
+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`.

 ## Deployment Order
 1. `databases/` — must be up before anything else
 2. `infrastructure/` — newt creates the pangolin network
