This puzzle was created as a birthday gift for Flinty, the absolute legend behind the famous Dutch Flat Mate puzzle series. He is an excellent setter, and just an all around cool person. Happy birthday!
Rules:
Rules:
- Normal sudoku rules apply.
- Dutch Flats: every 5 in the grid must have a 1 directly above it or a 9 directly below it. It may have both, but it doesn't need both.
- Ambiguity: each line in the grid is either a Between Line, or a Double Arrow, but NEVER BOTH.
- Between Lines: digits along a line must be strictly between the digits in the attached circles.
- Double Arrows: digits along a line must have the same sum as the digits in that line's circles.
Solution code: Column 9

Lovely puzzle! It is wonderful how you can deduce the ambiguous clues when asking the right questions. Also a wonderful use of the Dutch Flat Mates constraint. Thank you, Black_Doom!
