I think this is one of my harder puzzles. I’ve called it 4/5, but maybe 4.5/5 is more accurate?

Standard sudoku rules apply: each row, column, and 3x3 box must contain all the digits from 1 to 9.

Digits along an arrow must sum to the value in the attached circle.

Any group of three consecutive cells along a pink entropic line must contain one low digit (1,2,3), one middle digit (4,5,6), and one high digit (7,8,9).
