Wow, very lovely puzzle! I had to use the only possible placing of the magic square to place the last 5, then it was very satisfying to use that to fill in the digits on the whole board!
@JohnBoggs Assuming you've identified high/low cells correctly, there's only one possible orientation of the magic square that will fit the polarity. From that one orientation you can assign all the digits.

I could simply do negative XV every day, especially this great. Thank you.

really satisfying to colour everything and then place all digits for each colour at once!

I struggled so much with this but really enjoyed it!

loved how the logic for placing the magic square intertwines with the logic for assigning colors to X pairs.
please do more of these!

Great idea with the magic square to resolve digtis. I'll say this is 2 star difficulty if you're an experienced nurgler, and 3 if you aren't.
Edit: SPOILER help for JohnBoggs and others. Magic squares are very restricted, e.g. they always have 294 or 492 in one of their "sides". If your colouring differentiates between high (6-9) and low (1-4) digits, it's easy to spot which side can be a 9 in the middle flanked by low digits, and the rest unravels from there.

Nice beautiful logic throughout
