One night a woman named Mara arrived at his door with a MoodX still in its factory shell. “I need yours,” she said. Her voice had the calm flatness of someone who had learned to manage alarms. She explained she worked at an institution that collected mood data—aggregates for city planning, for emergency response. They’d noticed anomalies: neighborhoods where the average color line had begun to drift into a new spectrum, a slow resolve shifting overnight from Amber-Alert to Rose-Vivid. People were changing, and the data had stopped making sense.
