Night after night, the DSV56RJBK revealed small talents. It managed power cycles with a patience most devices lacked. It could smear out jitter in sensor sampling with a tiny adaptive filter, so delicate Mara suspected an author who had once listened to the hiss of a failing accelerometer and decided to smooth its last breathing. The code contained a scheduler that preferred graceful delays over brute force polling. Small, elegant choices. Whoever wrote this firmware had loved the machine it ran on.
