Rules
- Normal Sudoku Rules
- Place the digits 1 through 9 in each empty cell. Digits must not repeat within the same row, column, or box.
- Knight's Move Constraint
- Digits must not repeat in cells that are a chess knight's move apart.
- Reanban Lines
- Digits along each renban line must be a set of consecutive digits in any order, and must not repeat.
- Black Kropki Dots
- A black dot between cells indicates cell values with a 2:1 ratio. Not all dots are necessarily shown.
Difficulty
I put this in as a 3-star because the solve path becomes relatively narrow in the mid-solve. I expect the opening logic to be more of a 2-star. Thanks to the CtC discord community for test-solving and cornish-john for the feedback.

Thanks, good point about the notification.

Thanks @uvo! I totally see that the edit functionality was not designed for responding. However, there are two reasons why I think it is used in this manner.
- solvers are notified when their comment is edited
- it keeps comments and responses linked together
Therefore, I'd like to keep (mis)using the edit functionality like this as long as you (as a mod) don't have a problem with it.

The original comment is gone and cannot be restored.
The best way to avoid this is not to edit someone else's comment unless it is necessary. The ability to edit comments was never intended as a means to reply and is pathlogically misused.

Sorry vorash00! I have accidently overwritten your comment and don't know how to restore it. You were essentially saying that my difficulty note encouraged you to give the puzzle a go because you usually struggle with break-ins. Thanks! For me as a setter, this is very valuable feedback!

Very enjoyable puzzle, which is all about asking the right questions. I agree the mid-solve was tricker than the break-in, but it never felt unfair or as if I was losing momentum. Good work!
