Punishing, but rewarding. I spent hours chipping away at possible values of individual cells before the solution started to come into focus...

I found that it requires using bifurcation at a very advanced stage of the solve to eliminate a large number of cells. Without stronger logical constraints to guide the solve, this made the process feel quite mentally exhausting. By the time I finished, I didn't feel I had enjoyed the solve as much as I had hoped.
I also have the impression that the puzzle could have been even more elegant if there had been a bit more logical interaction between the bottom-right box and the box directly above it. Of course, that's my personal impression.

Brutal, but beautiful. I was surprised that disambiguation the last 4 digits would be so tough after the relaxing middle, part, just when I had taken a breath after the break-in.
