Corridor Test

The folded cardboard barrier and wooden marker stood firm in the floor seam. I stepped up to the line, planting my lead boot directly behind the cardboard edge. High guard locked, elbows tight against the vest. I worked a disciplined bob and weave through the narrow channel, keeping every slip within the two-inch clearance. My shoulder brushed neither the birch stick nor the clothespin post. Five smooth passes back and forth without shifting an ounce of dust. The corridor holds its alignment under pressure.
