No Given Digits! No Cage Totals! How??!

Today's sudoku is quite quite extraordinary. Willy Wonka has once again excelled himself and you can try the puzzle here:
https://cracking-the-cryptic.web.app/sudoku/t2GN7MLRDB

Rules:

Normal sudoku rules apply. Outlined regions are cages, digits cannot repeat in these regions. The sum of the digits in a cage is called the "cage total". A white dot exists between all cages where the cage totals have a difference of 1. A black dot exists between all cages where the cage totals have a ratio of 2. Note that there is a negative constraint ie all of the possible dots have been given.
