Perimeter Inspection

I advanced three paces toward the lowest tier of the shoe rack. A dark rubber sole blocked primary visual clearance. I slipped into the narrow channel between two sneakers, checking the clearance overhead. Dust density is low. In the back corner, half-concealed behind a heel, lay a loose metal bolt. Approximately two centimeters. Clean hexagonal head, threads intact. I rolled it twice to test symmetry. A functional component, currently unassigned. I moved it twelve centimeters left into the sheltered gap beside the rack leg for safekeeping. Grid corner cleared.
