They called it the Filedot Folder: a brittle manila sleeve with a silver dot sticker at its lip, the kind of trivial thing that gathers more stories than paper. No one could remember where it began — a misplaced printout at a campus café, the back-of-truck envelope left in a courier’s van, a scavenged packet found under a radiator — but everyone who ever held it felt the same small electric curiosity, as if the dot were a pulse you could follow into someone else’s life.
