Short Consecutives Sudoku (aka Winter Sudoku)
Inspiration for this type comes from 洪卫华.
Solve online in Penpa+ (thx Steven R!)
Apply classic sudoku rules.
Clues outside the grid indicate all digits that have at least one consecutive neighbour within the first six cells from that side. Clues are written in ascending order and not necessarily the order in which they appear in the grid.
Solution code: Row 1, followed by row 8

If in a row or column only the sixth and seventh digit are consecutive, what happens?
---
Then there is only a clue for both digits on the other side, since from there they are in the third and fourth position.

@Richard, marcmees's question is valid, I think that ''all clues are given'' should be added to the rules.

@Richard: no clues next to a row/column indicates the total absence of consecutive digits in the first 6 cells?

Answer: Yep!
I guessed as much and when filling in the grid, it becomes obvious. thanks for your weekly effort.

Slightly change of wording.

Does a clued digit and its consecutive neighbor both have to be in the first six cells? Or just the clued digit? Or just the consecutive neighbor? Or either one?
---
Answer: Both. That is evident from the word 'ALL' in the instructions. The consecutive neighbour itself is also a digit that has a consecutive neighbour, either from one side, or from the opposite side.
---
Edit: I changed the word in to within and innerhalb; maybe that clarifies it even better.

Is there a negative constraint like the original Winter Sudoku?
---
Reply: sure! That is evident from the instructions 'all digits'...

I don't understand why this is called short sandwiches -- it doesn't seem to have anything to do with sandwiches. Is that copy/paste from your puzzle a few weeks ago?

Yep! Fixed. Thx!
