Normal sudoku rules apply.
Digits do not repeat in cages, and sum to the number in the top left.
The blue squares contain a set of the digits 1-9.
Thank you everyone who tested this! :)
Solution code: the digits in the blue squares, left to right, top to bottom

Very nice puzzle, as usual! I found a lot of surprising interactions between the cages and disjoint sets, some tough deductions throughout but well worth the time to solve. Thank you very much for sharing! :)

Thank you! One very hard deduction towards the end, otherwise nice and smooth.
