In it she seems to say that the families who come to her mother's table on Saturdays are working the system. Grace takes four days to prove the recording was put together: a stretch of room noise that repeats, because a room doesn't repeat.The proof changes almost nothing. The Saturday clients stop coming.Then the district adopts Provenance, a library of forty AI-made history clips, each one carrying a citation to a real archive. Grace checks three. Two lead to single photographs. The third leads to a county road survey.The friends can go where a book was last put down, and the copy comes home blank. They use it to stand in rooms where a record was being made.Two Nights in Atlanta. Three More Rooms.ATLANTA, OCTOBER 1919: Nadia and Grace spend two nights at a reunion of Confederate veterans, which sets up a committee to decide what the South's schoolbooks will say about the war.
