In this puzzle, we delve deep into the world of organized crime. Your job as a detective is to expose the command structure of the criminal syndicate by finding the boss of each triad of killers. Good luck!

Rules:

Normal sudoku rules apply. Digits cannot repeat within a cage. If three cages are mutually adjacent (A is adjacent to B, B is adjacent to C, and C is adjacent to A), the sum of digits in one of the cages is equal to the combined sum of digits in the other two cages. Cages are considered adjacent if they share an edge.
