Positive Negativity 3

Normal Sudoku rules apply, place the digits 1-9 in each row, column, and box.

Yin Yang: shade some cells so that all shaded and unshaded cells form 2 orthogonally connected areas such that no 2x2 area is entirely shaded or unshaded, and all the digits values in the shaded area are negative values.

Killer Cages: VALUES in cages add up to the total in the corner.

Kropki / Consecutive Dots: VALUES separated by a white dot must be consecutive. All white dots are given.

Solve on CTC

This is a sequel to Positive Negativity,

and Positive Negativity 2.

I'm not sure what I'm doing wrong, but I can never fill box 4 without contradicting the kropki restraint.

~~
Be sure you remember the Kropki constraint is for values not digits.
That should resolve it for you.
