I'm the author of #67325. **I'm leaving this comment to explain why I closed
the PR.**
Since config changes require a restart, I don't think the default argument
evaluation at module load time is a bug.
I tried to reproduce the issue to identify the actual root cause, but
couldn't — the DAG files appeared in the UI correctly in my tests.
I tested both `airflow standalone` and separate `scheduler` + `api-server` +
`processor` setups.
Example files I used (same wrapper pattern from the issue description):
- `dags/wrapper/flow.py` — the wrapper decorator
- `dags/test.py` — uses the wrapper, also no keywords
```python
from datetime import datetime
from wrapper.flow import flow
@flow(schedule=none, start_date=datetime(2024, 1, 1))
def test():
print("hello")
test()
```
The DAG was discovered and visible in the UI after setting
`DAG_DISCOVERY_SAFE_MODE=False` and restarting.
