PUZZLE
[Iridescent Path]
[Iridescent Path] without note space.
RULES
Sudoku: Normal Sudoku rules apply; place the digits 1-9 once in every row, column, and 3x3 box.
Black Kropki: Cells separated by a black dot have one digit double the other.
Sumdex Lines: Lines are divided by 3x3 box borders into segments. The value of a segment is the sum of its digits modulo 10. (For example, a segment of {3,7,9} has value [3+7+9]mod10 = 9.) If the Nth segment (starting from the diamond) has value V, then the Vth segment must have value N.

The way the logic ricocheted off between the different lines was very pleasant indeed. Great puzzle!

Great modulo puzzle. Hard to do without notes. Loved it thx (underrated why?).

Glad you enjoyed it! There is a version with note space, I'll make that the default version for future solvers. - Sotehr
