Operator Challenge: guess the Rainbow Six operator one cell at a time

Same roster as the Operator mode, but a different operator every day and a harder rule: a guess uncovers a single cell of its row. The rest come with the following guesses, on every row at once. You reason on partial feedback for several turns, and each guess becomes a real probe rather than a full answer. Unlimited guesses, no game over, and stats kept separate from the classic mode.
