Normal sudoku rules apply.
Box borders divide each blue line into segments with the same sum.
Within a cage, digits must not repeat and they sum to the small number in the top left corner.
Solution code: Row 9

What a beautiful puzzle, it all flowed so smoothly! I really enjoyed the way all the clues interacted, and how each deduction impacted other parts of the puzzle -- and once I'd whittled away enough to fully get the break in, it was beautiful how the rest just fell into place!
Loving this series, and hope there will be more still to come!

A struggle at times, but managed to get through without any bifurcation or brute force. 25 minutes to get the first digit, and then rest fell within another ~20.
Loving this series!

What an incredible break! It was like sparring with the puzzle until you wore it down. Thanks for sharing!

Very tricky logic, hard to get through! As a previous commenter said, a bit brute-forcing was necessary on my side. But maybe I just didn't spot something ;)

Very very tricky this one. Brute force and ignorance solve unfortunately.
