Rules
Normal sudoku rules apply.
Shade some cells so that all shaded cells are orthogonally connected, and all unshaded cells are orthogonally connected. No 2x2 area may be completely shaded or unshaded.
The value of a shaded cell is equal to the negative of its digit, and the value of an unshaded cell is equal to its digit.
Within a cage, digits must not repeat and their values sum to the small number in the top left corner.
Solution code: Shaded digits in row 7
