Greyforge translates real greyhound behavior into a fictional operating system built from motion events, system states, and diagnostic failures. Vol.1 — Zoomies captures propulsion, instability, and full-speed override through Zoomies Initiated, Motion Surge, and Grip Failure. Vol.2 — System Modes expands the system into recognizable state changes like Sleep Mode Activated, System Reboot, and Treat Detection Mode. Together, the System Series forms the active Greyhound OS line: wearable interface graphics for owners who know the system.
