Lols - yes, here I am, and the answer here is particularly low-effort and easy, using, as we will, the oft-forgotten sculpt function, the Unsubdivide command, which you should get initially via shift+C / Command Manager.
Running that on the original collapsed SDS version will reduce it to its base cage, and you can then extract a polygon copy of the level 0 model from that using the sculpt layout / menus. What you can't do is just delete the sculpt tag, or do Current State to Object - neither of those will work here.
