note: Entity-relationship graph derived from the Airflow REST OpenAPI schemas and the nested path structure
  (dags -> dagRuns -> taskInstances -> xcomEntries). Airflow identifiers are natural keys (dag_id, dag_run_id,
  task_id, pool_name, variable_key, connection_id, dataset uri), not prefixed opaque ids.
