WHAT IT DOES

WHY IT NEEDS A POLICY

Why taskwarrior_undo needs a policy

This tool reverses the most recent Taskwarrior operation, which could restore deleted tasks, revert modifications, or undo completions. While it reverses changes (making it a form of write/modify), it is itself a reversible operation in the sense that data is being restored rather than permanently destroyed. It fits best under Write since it modifies task state.
