Really cool geometry here. I thought the RSL was a very elegant way to resolve the inherent ambiguity of the other parity/renban set up.

An extremely clever puzzle. It took me ages to figure out the break-in, but I'm glad I persevered because this is superb and really deserves to be solved. Thank you very much!

I got lucky when breaking the symmetry but honestly this isnt that hard and is very pretty
