Fill every row, column and 3×3 box with the digits 0-9, where 4 is the OFF (hidden) digit. All adjacent visible ON digits are neither consecutive (○), nor in a 1:2 ratio (●), nor do they sum to either 5 (V) or 10 (X).
The grid is covered (mostly) in fog. Placing a correct digit in a cell will reveal the surrounding cells.
Once in every row, column and box is a Schrödinger cell with a visible ON digit and the OFF digit 4. All ON digits appear once in a Schrödinger cell. Every Schrödinger cell has a unique position within the 3×3 boxes.
1. Two cells separated by a ○ have consecutive ON and OFF digits.
2. Two cells separated by a ● have ON and OFF digits in a 2:1 ratio (one digit is double the other).
3. Two cells separated by a V have ON and OFF digits which sum to 5.
4. Two cells separated by an X have ON and OFF digits which sum to 10.
5. The ON/OFF digit pair in any Schrödinger cell must not follow any of the connecting constraints.

The wording of the rules was very difficult for me to understand (the comments below was very helpful). Once I understood the rules, I thought the puzzle was incredibly fun to solve. I would love to see more puzzles with this kind of ON/OFF positive/negative rule set. Thank you, NotThatItMatters! :)

Thank you, very nice and brain-bendy puzzle! I enjoyed it!

Can you elaborate further on rule 5: The ON/OFF digit pair in any Schrödinger cell must not follow any of the connecting constraints?

Absolutely beautiful puzzle! This inspired me to create an account just so I could leave a review. I’ve always loved Schrödinger sudokus, but this was implements a very interesting twist.

Just for clarification of the rules:
Place the digits 0-3 and 5-9 in every row, column and 3x3-box (all the digits 0-9 except the 4).
Two adjacent (regular) digits must not satisfy a Kropki- or XV-relation.
In every row column and box there is a special cell. This cell contains a hidden 4 which should not be entered but which is relevant, because only this hidden 4 satisfies the Kropki- or XV- constraint with the neighbouring cells if given. The entered cell does not satisfy the constraints.
EG: If there is a X-Clue between two cells, one of them is a special cell and the other one is a 6. In the special cell no 3,5 or 7 can be entered because of negative constraints.
These special 4-cells each have a unique position relative to their 3x3-box. Each digit (but 4) appears exactly once in a special cell.

Just to clarify that In order to make solution code work, the off digit (4) should not be entered (8 digits total should be entered)
-----
@asp1310, basically all contrains given affect digit 4. The rest of the digits must obey negative constraint restriction ( no dots, V or X allowed between the rest of the digits)

Can you provide a small example grid of the rules in practice? It sounds fun but I only half-understand what it means.
