Can of worms

Sudoku: Fill each cell with a digit from 1-9, with no digit repeating in a row, column or 3x3 box.
Each orange line is both an index line and an entropic line.
Index lines: starting with the diamond at position 1, the digit at the Nth position along the line indicates the position of the digit N on the line.
Entropic lines: every set of 3 consecutive digits along the line contain one low digit (1,2,3), one medium digit (4,5,6) and one high digit (7,8,9).
The arrow points to the smaller of the digits in the cells it occupies.
For those unfamiliar with index lines, the rules simply imply:
If the line is of length N, only the digits 1 to N appear, once each
Each digit is either (a) in its own place (e.g. 3 in 3rd place), or (b) has swapped with one other number (e.g. 2 in 5th place and 5 in 2nd place)
Solution code: Row 5

In the Android app, the arrow is rendered the wrong way round which first lead me to a wrong solution.

I love a coloring puzzle, so this was fun :) I was stuck on the break-in for a few minutes, but then it flowed very nicely

I loved this ruleset and the logic of this puzzle, although I forgot about the index line rule in the end and was a little perplexed for a few moments. XD Thank you for setting!

Fun idea and well executed! Seemed too unrestricted at first but slowly and cleverly gave way :]
