Cage of War

This puzzle was set for Sevenatenine birthday. This puzzle works similarily to fog war, except placing a colour might reveal part of a cage.

Rules:

1. Place the digits one through nine once each in every row, column, and 3x3 box.

2. Shade in two colours, that both colours form two orthogonally connected regions. One of the colours will represent negative values and the other positive values. No 2x2 region is fully one colour. Place a colour in the cell once it is determined to be either a positive or negative value.

3. Values in cages sum to the value of the top left corner of the cage. Standard killer cages. Digits do not repeat in a cage. Cages do not overlap. The cages will become known from the colouring. Pre-Colouring is not needed. Darker colours will make the cages more visible.

4. Values separated by a white dot are consecutive.

5. Values separated by a black dot have a 1:2 ratio. One value is twice the amount of the other.
