This was fun, thank you for setting. It was hard not using uniqueness at some point as a shortcut :)

This puzzle flows really nicely when you read the rules properly... Had 2 false starts (one where I mixed up entropic and modular, and one where I missed "including itself"), all entirely my own fault. After that, enjoyed it thoroughly!

I liked how I had to keep my mind switching gears along the way

woop woop first! And what a beauty it is! Somehow my mind really jibed with this one, I solved it in 18 minutes (with distractions! :) ). The logic is gorgeous.
