Negative Quantum Friendliness
(Published on 17. August 2022, 11:25 by mk6614)
-Friendly Schrödinger's cells hold two digits; the first being it's box index, the second it's row or column index (or both). Digit 0 corresponds to exacly one index 1-9, which can be determined.
-Negative white kropki: A dot between cells indicates cells with consecutive digits, where 0 is consecutive with 1 and 9. All dots are shown. Consecutive digits may also not coexsist (i.e. Schrödinger's cells may not be composed of consecutive digits).
-Odd/even: digits on squares must be even. Digits on circles must be odd.

Solution code: The 7th row, where Schrödinger's cell is written as 2 numbers, with the smaller one coming first (10 digits).

Quite difficult, some bifurcation was used in the mid-solve but very interesting logic. Thanks for sharing!
Notes:
Since it does not specify in the rules the interaction if a schrodinger is on/off a kropki dot, this is what I assumed (it didn't look solvable otherwise)
- A dot connects cells where both schrodinger digits are consecutive ([13] and 2 is allowed, [15] and 2 is not allowed)
- If there is no dot, neither digits of the schrodinger are consecutive ([13] means adjacent digits cannot be 0, 2 or 4)
The rule "Digit 0 corresponds to exacly one index 1-9, which can be determined." means that for exactly one of the Schrodinger cells, one of the cells' digits can be replaced with 0. (So one Schrodinger eg [48] can be turned into [08] or [40])
