Both par2 verification/repair and extraction are done by external utilities, over which we have little control.
For the "temporary download folder" you can set a minimum free space, below which downloading will be stopped.
Any running repair job will continue.
So make sure you set a safe threshold.
The final destination drive is not guarded, but any failed unpack can easily be retried from the history.
