This puzzle is the first time I have seen the Contract Killer Cage constraint. Check the rules below carefully.

📋 Puzzle Rules:
• Normal Sudoku rules apply.
• The grid is covered with fog. There is an initial light source that clears the fog. Placing correct digits into cells clears the fog from all adjacent cells.
• Killer Cages: Digits inside Killer Cages may not repeat and their values must sum to the total in the top left corner, if given.
• Arrows: Values along an arrow must sum to the value in the circle. All arrow sums are contained in 1 cell.
New Constraint Rules:
• Contract Killer Cages: Every Killer Cage in the grid is also a valid Contract Killer Cage. Contract Killer cages must have EXACTLY TWO non-zero values. The top-leftmost value in a Contract Killer cage points to a row in the grid, and the bottom-rightmost value points to a column.
• The order priority is given to the topmost value. For example, if R7C3 and R8C2 are valid non-zero cells in the same Contract Killer Cage, R7C3 would count as the top-left-most value and would therefore give the row coordinates.
• The row and column coordinates from a Contract Killer cage combine to target a single cell in the grid. The said cell is "assassinated" and its value is multiplied by 0.
• No two Contract Killer cages may target the same cell.
• All cells with a value of 0 are counted as assassinated and must have a corresponding Contract Killer cage.
