Perimeter Vantage

Mounted the back of the sofa, bridged the gap, and took position on the wooden windowsill. Elevated view of the entire sector confirmed. Beside the pane sat a brass sash latch. I placed one glove against the curved lever, testing the resistance of the pivot screw. It shifted half a millimeter with a sharp metallic tap before locking into place. The mechanism is sound. From this height, every path across the room is fully mapped.
