Feeling Rough

Sudoku: Place the digits 1-9 once in each row, column, and 3x3 box.
Fog: The grid is partially covered in fog. Placing a correct digit might clear some of the fog somewhere in the grid. No guessing is required.
Circles: A digit in a circle indicates roughly how many circles contain that digit i.e. X in a circle indicates that X appears in either X+1 or X-1 circles (but not in exactly X circles). All circles are visible i.e. no circles are hidden behind fog.
Entropy: Orthogonally adjacent circles must have different entropy i.e. a digit from a different set {1, 2, 3}, {4, 5, 6}, or {7, 8, 9}.
Arrows: Digits along an arrow sum to the digit in the attached circle.

Updated the link to the puzzle to fix the arrow circle drawing. There was an older version of the puzzle where the arrow circles were drawn differently to the rest of the circles. Continue with this version if you previously started solving: https://sudokupad.app/nmzsv3jbx9

Really cool idea, excellently executed. Both phases worked nicely.

Absolutely brilliant puzzle! Solving it was hard, but constructing it is ingenious. Take a bow! Thank you:)
