Why the answer key can be trusted
Puzzles here are carved from a completed grid, one clue at a time, and re-solved after every removal to confirm exactly one solution still remains. Any clue whose absence would allow a second answer is put back. The published key is the grid the puzzle came from, so the two cannot disagree — which is not true of sheets generated by removing clues at random.
