@TommiH row 4 col 3 is adjacent to a 2, which disambiguates.

I can't see what disambiguates the 3s and 7s in the puzzle. Couldn't find any instance of the negative constraint that would apply regardless of which way I'd flip them. Perhaps I'm just blind...

Relaxing compared to recent weeks but still lots of fun
