Yes, this is a nice presentation of the idea indeed! I also like the mysterious stipulation "How does this end?".
To the best of my memory, my earlier version didn't attempt to disprove black on move, so this one is better.
A challenge remains to do the same with castling on the long side but this is of course irrelevant in your MDR-project now that the 'minimal deviation' point has been made.
Best, Guus Rol.

Here we inform the problem we were talking about:
Jorge Lois & Roberto Osorio
Peña del Mate de Ayuda- Buenos Aires
How does this end?
Minimal Deviation from the Rules (MDR)
MDR is a modified convention to present a diagram (article under preparation) The basic idea is that the diagram MAY be illegal as the result of a last geometrically correct illegal move. Then, retraction 7.4 of the Laws has to be made and assume the art. 4 consequences.
This way, nothing has to be explained regarding fraction of move when presenting the problem and the solutionist has to find by retroanalysis all the details.
Article 4.6 forces white in this problem to mate by O-O.
A traditional presentation of this problem would be #0.5, but obviously this is much weaker than the MDR alternative.
