Solution code: Box 1 and then Box 9, both in order from the left of the 1st row of each to the right, and then from top row to bottom row.

I updated the link to reflect the changes that I made in f-puzzles, namely your (Puzzle Weasel's) request for the lines to be pale, rather than black.

Nice logic, thanks.
A small suggestion to improve the experience: the black lines you've drawn to clarify the arrow directions make it difficult to read candidates in those cells when using f-puzzles. Using a different (pale) colour for those lines would be better as then you can read the numbers which are drawn on top.
