Half Circles
Rules:
Normal sudoku rules apply.
A digit N placed inside a circle or semicircle indicates that exactly N full circles in the grid contain the digit N.
Two semicircles together count as one full circle. For example, if there are four semicircles containing the digit 5 and three full circles containing the digit 5, then the total count is 2+3=5 circles with the digit 5.
Lösungscode: Row 1.

Amazing puzzle!
I know it's not relevant to the solve, but the "Two semicircles together count as one full circle" rule seems slightly ambiguous to me. What happens if the digit appears in an odd number of semicircles?
For example, if you had a 1 in three different semicircles and no full circles would it count as being in 1.5 full circles or 1 full circle? Just wondering in case this ruleset is used for harder puzzles in the future!

Absolutely brilliant puzzle! I'm amazed how cleanly it solved, it felt very much like the path was a carpet being unfurled in front of me. Thank you for creating this!

I really liked the addition of semi circles in this ruleset, definitely 1 star, but I would absolutely love to see what this constraint could offer in tougher puzzles!

This was fascinating. I really want someone to do a proof video on why it works the way it does.
