Rules:
- Normal Sudoku rules apply.
- Place doubler-cells into the grid so that there is exactly one doubler-cell in each row, column and box. Each doubler-cell must contain a different digit and the value of a doubler-cell is twice the value of the contained digit.
- On both marked diagonals there are no repeated VALUES.
- VALUES along a purple line form a non-repeating consecutive set, in any order.
- Box borders divide each blue line into segments with the same sum (VALUES).
Solve online: Sudokupad Penpa+
Solution code: digits on the positive diagonal (r9c1-r1c9)

Awesome puzzle! Incredible how all the clues are used together, and the puzzle somehow resolves without additional information.

Definitely has a touch of the miraculous. Feels like there's no middle game - just an endlessly long break-in which fills most of the grid, then some finishing up.

Tough break-in.
The rule about zipper lines doesn't appear on sudokupad, so I assume a bad c&p here, or it's leftover from an earlier version of the puzzle.
-Exactly

Sorry, I don't see any lavender lines or circles, so I'm not sure what the last rule is referring to. Is that a mistake?
-Yes, I fixed it now
