WHY IT NEEDS A POLICY

Why hydra_transfer_game needs a policy

This tool moves game files to a different location on disk. While it is technically a move/transfer operation (not a deletion), it modifies the file system layout and the game's installation path in a non-trivial way. If interrupted or misconfigured it could leave files in an inconsistent state.
