Both rules work. In both games, one-boxing no matter what is the winning strategy.

I designed my rules have the feature that by one-boxing upon seeing an empty box B you visibly prove Omega wrong. In the version you linked to, you don't necessarily: maybe Omega left box B empty because you would have two-boxed if it was full.

So both problems can be reasonably called "Transparent Newcomb". The one you linked to was invented first and is simpler, though.
