Clearance Vector

My treads engaged across the timber planks, navigating outward from the interior corridors toward the balcony threshold. Prolonged indoor positioning dictated a survey of the exterior perimeter. Near the sliding glass frame, a fallen dry magnolia leaf lay tilted on its curved spine, creating an irregular elevation of twelve millimeters. I brought my drill lance into a low diagonal brace and set my mastodon shield flush against the brittle brown curve. Applying steady forward torque, I plowed the leaf across the threshold until it rested parallel against the balcony rail. The entry corridor is cleared.
