Normal sudoku rules apply.
Adjacent digits on green lines must differ by at least five and each line must contain exactly one repeat digit.
Once a digit has appeared on a line as a 'repeat digit,' it may not do so again.
Antiknight: Digits cannot be a knight's move (in chess) away from themselves.
Digits in cages must not repeat and sum to the total in the top left corner.
Solution code: Enter Row 1

Beautiful puzzle; anti-knight coloring is my favorite, and making the GW lines "almost renban" made for some great subtle logic.
