a changed man

I made this puzzle following a spontaneous prompt from roflsalot about the antiknight constraint and dutch whisper lines in a full rank puzzle.
Inspired by The Book Wyrm's Prestige.
- Normal sudoku rules apply.
- Cells one chess knights move apart may not contain the same digit.
- Adjacent cells along the orange loop must have digits with a difference of at least 4.
- The value of a cell on the orange loop with a digit D is equal to the digit D steps clockwise along the loop (direction indicated by arrows). The value of a cell not on the loop is equal to the digit on it.
- The values on columns and rows, read in both directions, make a total of 36 nine-digit numbers. Outside clues show the rank in ascending order among those 36 numbers for the indicated column or row in the direction of the clue. There are no ties in rank.

I forgot about anti-knight and managed to solve it without bifurcation! I am both very proud of myself and very annoyed, because I believe I made it much harder than needed.
Still, a gorgeous solve! And with two difficulty levels to boot :3

Clarification: digits are used for Dutch Whispers, and values are used for Ranking.
For example, r1c6 and r2c7 will have digits with a difference of at least 4, but the nine-digit number corresponding to column 6 read from top to bottom starts with the value pointed by r1c6 along the loop, not with the digit on r1c6 itself. Say r1c6 has a 7, then both r2c57 will have digits from 123, but the value of r1c6 is taken from the digit seven steps along the loop, that is, from r7c8.

uhjeez that twisted my brain, it took me quite some time to realize what your ruleset actually means... that was -for me- tough as a nail, took me the best part of two hours (just under 110mins) and I feel dizzy...
In fact i was so inconfident most of the time that I hit the check button every now and again luckily I was correct with those -what felt more like- educateded guesses. :-D
Great puzzle! brain still hurts..
I need a few one and two star ones to compensate now LOL

oh my, do you have a suggestion for a better wording on the loop rule?

I completely forgot about the knight's constraint, and, as a result, struggled way too much with this (also the solution code doesn't seem to be working)

oops, looks like i can't count, should be fixed now

I would like to point out that I had no part in the inspiration for this. In fact, I think a world with anti-knight, dutch whispers, and full rank is a hellscape.
