Rules:
- Normal sudoku rules apply.
- The grid is partially covered with fog. Correctly placed digits will clear the fog around that cell. No guessing is required.
- Digits separated by a white dot are consecutive. Digits separated by a black dot are in a 1:2 ratio. Not all dots are given.
- Draw a 1-cell-wide "wall" that divides the grid such that the white dots are separated from the black dots. The wall cannot branch or touch itself (even diagonally).
- Dots can touch the wall, but they can't be on top of it.
- Digits that share an edge with the wall must be at least 4 lower than their orthogonal neighbors on the wall.
- Adjacent digits on the wall must be consecutive.

Lovely puzzle. I really enjoyed it. An unusual yet simple ruleset that has some lovely implications once you understand them.
