Rules:
Normal sudoku rules: Place the digits 1 to 9 in each Row, Column, and 3X3 box.
Yin and Yang: Shade some cells such that all shaded cells are orthogonally connected and all unshaded cells are orthogonally connected. No 2x2 area may be fully shaded or fully unshaded.
Sight Lines: Digits in a cell containing a circle indicate how many cells of the same color (shaded or unshaded) are seen orthogonally from that position, including itself. The "other" color blocks vision.
Sight Lines Sum: For each cage, all cells of the same color (shaded or unshaded) that are seen orthogonally from that cage position (including the cage cell) must sum to the small number in the top left corner of the cage. The "other" color blocks vision.

I really loved this puzzle. It is one of my favorite mashups of rule sets. It never felt tedious and I never hit a big road block.
Thank you for including solution check. I find it so much less frustrating to be able to confirm that I am on the right track or find a mistake before it gets me too far astray.

Absolutely loved this. One of those puzzles that, for me at least, seemed absolutely impossible at the start but actually flowed quite easily once you begin with the right question.

Absolutely adored this! The sightline arrow + sum combo was a real treat, and the geometric leverage you got from your sums was very impressive. Thanks!
