Jade never announced the deployments. P0909 appeared in pockets and corners—on a windowsill by the music practice rooms, inside the greenhouse where biology majors napped under philodendrons, below the bleachers where athletes pretended their exhaustion was discipline. The device preferred anonymity. It learned faces as patterns and measured exhaustion without judgment. Its updates—the UPD in the label—came like weather systems: an overnight calibration here, a firmware whisper there.
