+## Packaging Boundary
+
+The repository is a uv workspace with `device-agent-runtime` as the root
+member and outer platform packages as separate members. The cloud platform is
+owned by `packages/cloud-platform` and may depend on the Runtime through an
+explicit workspace source; the Runtime distribution must never depend on or
+package `cloud`.
+
+All Python members share the committed root `uv.lock`. The Vue/Vite `console/`
+remains outside the Python workspace and keeps its independent npm lifecycle.
+
 ## Change Discipline
 
 Future changes must keep the dependency direction:
 
 `core` -> `driver`/`device` -> `tools` -> `perception` -> `storage` -> `runtime`
--> `api`.
+-> `api` -> optional outer workspace applications.
 
 When a change needs a new external integration, add it at the adapter layer
 that owns that concern, not at the domain or device boundary.
