Beautiful constraint, and nice use of the existing possibilities. Thanks for setting

Outstanding puzzle. Unless this is an existing constraint, we should call this the Lefkowitz Line

Bizarely, the grid is 90° anticlockwised rotated when I click on the image. And the solution code become column 1 from below to top. Very weird.
Very cool puzzle by the way.
