Special thanks to FIT7Y for test solving and feedback. I hope everyone enjoys the puzzle. Please let me know how you get on.
Rules:
- Normal sudoku rules apply.
- Digits cannot repeat on the thin blue diagonal.
- Digits cannot repeat at corresponding box positions (i.e., disjoint subsets).
- Digits in a cage sum to the number given.
- Digits on a pink line form a set of non-repeating, consecutive digits in any order.
- Box borders divide the thick blue lines into segments of equal sums. Different lines may have different sums.
Solution code: Row 9, left to right, no spaces.

This puzzle requires you to know some tricks about the disjoint set. If you know it then it is a 2-3* difficulty puzzle. Otherwise it requires considerable effort to figure out and 4* is more appropriate. Since disjoint set puzzles don't appear to be common, I have rated this 4* difficulty. Thanks for sharing!
I agree and thank you. KMD
