1. The book club's reading log

An eight-member book club has met monthly for three years and wants to start tracking, properly this time, which member has actually read which of the group's picks — right now it lives in someone's memory and the occasional "wait, did you finish it?" in the group chat. The list grows by exactly one book a month, membership hasn't changed in over a year, and nobody has ever needed to prove *when* a member finished a book, only whether they did. Run this through the six pre-build questions. Which one ends it, and what should the club build instead of a graph?
