4* difficulty in my opinion, great puzzle. I guess the implications of the 789 rule were clear after the first incident of breaking the puzzle. After that the puzzle didn't seem to tricky.

Excellent! This could be categorized as a zombie-puzzle, because seven also ate my brain. I made a wrong deduction at the start that haunted me for over 2 hours. Very hard from start to finish and a very rewarding solve. Thank you
