- Added new task for Scrimmage (学園交流会) in `ba_auto/tasks/scrimmage.py`, allowing automated clearing of the hardest stage (D) in three areas (トリニティ, ゲヘナ, ミレニアム) based on date-ordinal rotation.
- Introduced AP cost verification to ensure sweeps only occur when the cost is confirmed as 0 due to the user's monthly pass.
- Updated `ba_daily.py` to include the new scrimmage task in the daily preset and task registry.
- Documented the implementation details and testing outcomes in `plan.md` and `mapping.md`.
- Conducted live tests confirming successful execution and correct handling of ticket and AP costs.
