Lee-W opened a new issue, #65923: URL: https://github.com/apache/airflow/issues/65923
### Body ### What When a downstream rollup has already fired for a window that included an upstream partition, and that upstream partition is later cleared and re-run, the framework needs a defined behavior. Example: the monthly rollup for 2026-03 already fired with 2026-03-15 included; user clears and re-runs 2026-03-15. Does the rollup reprocess, hold, or no-op? ### Open question Auto re-trigger the rollup, require explicit user action, or expose a per-timetable policy? ### Related #59294 ### Committer - [x] I acknowledge that I am a maintainer/committer of the Apache Airflow project. -- This is an automated message from the Apache Git Service.
