Apache Airflow stable REST API boundary

Evidence-backed facts

1. Apache Airflow documents a stable REST API for DAGs, DAG runs, task instances, datasets, pools, variables, connections, users, roles, and related resources. informative
2. GET and list calls are distinct from creating DAG runs, changing state, managing variables or connections, deleting resources, and administrative actions. informative
3. API authentication, RBAC roles, deployment configuration, secret backends, DAG code, executor, network policy, and object permissions bound actual access. informative
4. An API response or created DAG run does not prove task success, idempotence, data quality, external side effects, or a secured scheduler deployment. informative
