Dot Mirage 2 by Derek LeClair

This is a follow up to my previous puzzle. I deduced the logic to fill in the grid from 2 digits does exist and here it is! The logic is a bit tricky but thinking closely about the negative constraints helps.

Normal sudoku rules apply.

A digit in a cell with arrows facing outward must be greater than all of its orthogonal neighbors.

On a black dot, one digit is double the other. On a white dot, the digits are consecutive.

ALL possible dots are given!
