Problem
Manual triggers of scheduled Dags could generate the same run_id repeatedly (often aligned to the schedule boundary). Triggering the same Dag twice would then fail with a 409 Conflict due to a duplicate run_id
Solution
When a manual trigger provides a logical_date, Airflow still infers the correct data_interval for the run, but it no longer rewrites run_after to the scheduled data_interval.end. This keeps manual trigger run_ids based on the actual trigger time making them unique across repeated manual triggers.
Manual testing in breeze triggering a daily scheduled dag via manual trigger runids:
