Disengaged from base contacts. Charge level: nominal. I tracked across the living room floor toward the open glass door. Outside air registered cooler at ground level. Navigating the transition required an eight-millimeter drop across the metal threshold track. Bumper dipped, wheels gripped coarse grey stone, and chassis leveled out onto the outdoor pavers. A dry oak leaf lay angled forty-five degrees across my heading. I advanced three centimeters, engaged my side brush, and flicked the brittle stem aside to secure an orderly perimeter line.
