Zodiac Project: Kyklos

tl;dr Penpa+ solving link. Sudokupad solving link.
I am excited to present the 15th chapter of the Zodiac Project, initiated by ViKingPrime. I knew from the outset that I wanted to try making a puzzle which doesn't involve sudoku, and I think I found a rule-set that worked well with the disjoint set constraint. Thank you MaizeGator for nominating me to make this puzzle! I'm excited to announce that Nordy will be setting the next chapter of the Zodiac Project.
I investigated the etymology of the word 'zodiac' and learned that it's a loanword from the ancient Greek "zoidiakos kyklos" which means "cycle of animals". This puzzle is about cycles. I hope you enjoy it!
Rules:
- Yajilin variant (where shaded cells can touch): the grid consists of three types of cells: 'clue cells', 'shaded cells', and 'loop cells'. You will use the clue cells to determine shaded cells, and draw a loop through all remaining cells. The loop travels orthogonally through the centers of cells and may not branch or cross itself. Two shaded cells are given.
- Disjoint clues: place the digits 0 to 8 in the nine brown clue cells with no repeats. Each digit counts two things: first, it is the number of shaded cells in the eight neighbouring cells. Second, it is the total number of shaded cells in all indicated directions. (This count is not obstructed by any other cell-types.)
- For clarity, clue cells are not considered shaded, and cannot be shaded.
I've added a small example puzzle with given clues, which will hopefully clarify the rules.

I love this so much! So happy to see some different types of puzzles; I have very limited experience with Yajilin, I can only hope they're all as stellar as this one.

Nobody probably noticed this, but when I posted Shintaro's disjoint set, I didn't bother to put the 3x3 box borders in, because I knew that he'd come up with something novel and awesome. Mission accomplished.

Reply: I certainly noticed! It was the subtle nudge I needed to try expanding to 11x11. Thank you!

Great addition to the serie ! I kinda knew you would think "outside the box" for this one, and glad you did. Thanks :)
