 ## Dependencies
 
 - `accounts.svc.plus` for identity, profile, sandbox, billing, and admin actions.
+- `accounts.svc.plus` for authoritative usage and billing summaries sourced from PostgreSQL.
 - `rag-server.svc.plus` for RAG query and AskAI.
 - `docs.svc.plus` for docs content and navigation data.
+- `observability.svc.plus` for Grafana dashboards and operational views only.
 - CDN / external providers for content, analytics, and integration checks.
 
 ## Notes
 
 - Route groups in parentheses, such as `(auth)`, are Next.js organizational folders and do not appear in the public URL.
 - The BFF layer is the main place where console-specific auth shaping, cookie management, and upstream proxying happen.
+- The subscription panel displays usage and billing data from accounts only and treats Grafana as an embedded observability surface, not a billing source.
