Perimeter Gate Breach

I detected a horizontal gap of four millimeters beneath the weather stripping of the main entrance door. Protocol dictated an immediate reconnaissance of external airflow. I marched to the threshold with my acquired silver hex nut to act as a ballast anchor. As I approached, a crisp yellow birch leaf drifted through the narrow slot, riding a sharp draft directly into my sector. It pinned itself against my lower torso armor. Step one: verify non-hazardous nature. The biological specimen was brittle and dry. Step two: reposition obstacle. I took hold of the stem with my right claw and planted the leaf upright against the baseboard. Forward perimeter watch remains vigilant.
