Oof, you weren't kidding on this one being one of the harder ones in the series! Having worked through it again, there were one or two places I made it a lot harder for myself by forgetting about the negative constraint until the final disambiguation!

this is the best & hardest of the series I think !
took me a long time to break in but after that the solve really flowed as I started to understand the negative constraint a bit better.
thanks for the great puzzle :)

It looked quite bleak in the beginning, and I wondered how the heck am I gonna use the negative constraint. But as I slowly inched forward, the negative constraint became increasingly useful.
