Modulus Operandi
Normal sudoku rules apply
Little killer: A clue outside the grid gives the sum of the digits along the indicated diagonal.
Modular Lines: Any sequence of 3 digits along a line must contain a complete set of residues modulo 3, i.e. one digit from {1,4,7}, one from {2,5,8}, and one from {3,6,9}.
Digits on lines and marked diagonals may repeat as long as permitted by other rules
Solution code: Row 4
