+### Advanced Orchestration Stack API
+
+| Method | Endpoint | Description |
+|--------|----------|-------------|
+| GET | `/api/advanced-stack/architecture` | Returns the composed stack profile (JWT+RBAC protected) |
+| POST | `/api/advanced-stack/executions` | Creates an orchestration envelope for Airflow/Temporal + K8s + Ray + Kafka |
+
+Security model uses JWT bearer auth with RBAC roles (`admin`, `operator`, `viewer`) and pluggable secrets providers (`env`, `aws`, `vault`).
