Very cool idea, I love the execution (wait… no pun intended >_>). The tension really builds as you read on, and there’s this really interesting ambiguity at the end where there’s not technically any further procedure after the 5th question (no 6th exchange, so no opportunity to accuse/confirm for the 5th), but the outcome is obviously already foreclosed.
Thanks for sharing the commentary, it’s always lovely to see how people think through their own work.
