I had to stare at this for over an hour (admittedly distracted doing other things too) before I started to make any meaningful progress, but once you ask the right question it flows beautifully. There was one other sticking point (where my notation had to undergo a regime change), and I either made a wrong deduction or I got my pencil marks backwards at one point which needed a fix, but if you take it slow and steady I think this is achieveable.

No way this is only 3 difficulty - 3⅔ for me, and the LMD average will surely be 4 if not 5.

Absolutely stunning. Fresh logic put to extraordinary use. Several moments of pure joy in my solve. Thank you!

Brilliant. A bit closer to 4* than 3* for me.
Very well done.
