### Reproduction on Airflow 3.2.0 I reproduced this issue with the following environment: * Airflow 3.2.0 * Python 3.12.3 * Ubuntu (WSL2) ### Summary I created a DAG using TaskFlow API with dynamic task mapping and triggered it multiple times. Initially, the DAG was detected by `DagBag` but not available in `DagModel`, causing: ``` DagNotFound: Dag id TEST_DTM not found in DagModel ``` After running: ``` airflow standalone ``` the DAG was properly registered and triggers succeeded. ### Observations After triggering the DAG three times: * `dag_version` table contains **3 rows** for the same DAG * version numbers incremented: **1 → 2 → 3** * `serialized_dag` and `dag_code` also contain multiple entries ### Conclusion The DAG version increases across repeated triggers even though the DAG definition does not change, which confirms the reported issue. I have collected logs, database evidence, and screenshots locally. <img width="862" height="247" alt="Image" src="https://github.com/user-attachments/assets/e9d8ce55-041e-4c18-9c1e-48e2129b4bd4"; /> <img width="1066" height="491" alt="Image" src="https://github.com/user-attachments/assets/3db52b40-66cd-4792-94b9-c4215fee8f2a"; /> -- This is an automated message from the Apache Git Service.
