AI Summary: The task is to debug a runtime error in the PyPantograph project, specifically a `RuntimeError: There is no current event loop in thread 'MainThread'` that occurs when importing the library in Python 3.12. The error stems from the use of `asyncio.get_event_loop()`, which is deprecated in Python 3.12. The solution likely involves updating the `pantograph` library to use the newer asyncio event loop mechanisms compatible with Python 3.12.

AI Summary: Refactor Pantograph's tactic execution system to improve sustainability and scalability. This involves creating a unified tactic execution function (`goal_tactic`), a category switching function, and modifying the system to report goal categories after tactic execution. Suggestions are requested for the detailed implementation.
