Antimatter Crystals

Each digit can be either a normal sudoku digit or an anti-sudoku digit. Normal digits appear exactly once in each row, column, and box. Antidigits cannot appear exactly once in any row, column, or box. Each antidigit must appear a total of nine times.

Digits along a purple line must form a non-repeating consecutive set in any order. Digits within a cage must not repeat and must sum to the given total (these rules apply to both normal digits and antidigits).
