Perimeter Lock

I reached the recessed corner between the sofa base and the wall at 21:24. The area presented minimal foot traffic and total overhead cover. A cylindrical wooden block lay discarded against the fabric skirting. I knelt, gripped its flat face with both gauntlets, and leveraged it eighteen millimeters forward until it locked firmly into the structural corner gap. It creates an immovable perimeter anchor. I seated my back against the dense wood grain, blaster resting across my knees. Night observation protocol initiated.
