A little twist on the classic 159 problem which is relevant to the added constraint. This puzzle went through a few iterations, but the final one was with the assistance of an amazing setter, Qodec. He taught me an important lesson about setting overall and I really needed to give him a shoutout for his contribution.
Rules:
Normal sudoku rules apply.
Along green lines (german whispers) digits must exhibit a difference of at least 5 with their neighbouring digits along the line.
Digits in column 1 give the positional index of the digit 1 in their respective row. For example, if we put 3 into r5c1 we would need to put the digit 1 into r5c3. The same applies for columns 4, 6, and 9.
Links:
Solution code: Row 7 followed by column 2 (18 digits, left to right, top to bottom, no spaces/commas).

A cool twist on the 159 subgenre, with some neat interactions between the mechanics!

Nice twist on the usual 159. I enjoyed these interactions immensely.
