I think this is the puzzle I am most proud of having solved, although I needed 2 attempts. And I had a blast doing it, thanks!
I ended with a 200-lines TXT file (not counting empty ones) to keep track of calculations. Quite a challenge.

Fantastic logic, as usual. Loved the break-in, and the rest of the solve was just as brilliant.
