Another new constraint for me - this time it's indexing lines! Much thanks to Sujoyku who spotted a clue that opened up this puzzle and saved it from some annoying scanning.
Rules:
- Normal sudoku rules apply.
- Index Lines: On an turquoise line, the digit in the Nth cell along the line (starting from the diamond) indicates the position along the line where the digit N appears - Eg: 3214 would be a valid line; the 1st digit, 3, indicates that the 3rd digit is a 1, and so on. If multiple lines exist with the same diamond, each line is treated as separate.
- Dutch Whispers: Adjacent digits on an orange Dutch Whispers line must have a difference of at least 4.
- XV sums: Digits with an X between them sum to 10; digits with a V between them sum to 5. No negative constraint.
- Kropki Dots: Digits with a white Kropki dot between them have a difference in value of 1. Digits with a black Kropki dot between them have a value ratio of 1:2. No negative constraint.
Solution code: Row 4 digits, left to right

Rules were unclear as to whether the diamond was part of the indexing line or not. The example 3214 made it seem like the index lines were of length 4, not 5. After I figured out the lines were of length 5, it was a great puzzle with some fresh logic!
