Normal sudoku rules apply. Normal rules for renban (purple), German whispers (green), and black dots apply. There are no negative constraints of any kind.
Renban Lines: The purple lines in the grid are renban lines. Digits on a line form a set of non-repeating, consecutive digits in any order.
Black Dots: Digits separated by a black dot have a 1:2 ratio, meaning one is exactly double the other. Not all dots are necessarily given.
German Whispers: Green lines in the grid are German Whispers lines. Adjacent digits along the line must have a difference of at least 5.

Loved this. Took me ages to spot the initial logic, but when I did I found it delightful, and although I did get dreadfully stuck once more through the solve, again the solution was lovely. Many thanks to the setter.

Beautiful puzzle but probably around 3*
[I was torn between 3 and 4 but won't be at all surprised if this ends up at 3. Thanks for the kind words! -z]
