Frankly the plot to stay undiscovered within Hogwarts stretches credulity regardless of whether Harry gets clues about Quirrel’s real identity. As readers we forgive it because 1. it’s part of the setup, where luck and coincidence are more forgivable and 2. it’s also in the canon books.
But I suppose to steelman it one might suppose that Voldemort simply accepts a high risk of being discovered, has a plan to escape if that occurs, and is fortunate to not need it. Both Harry and The Stone are in Hogwarts, there’s no risk-free method of accessing them.
