Perimeter Inspection

A deep mechanical thrum drew me past the threshold. I marched through the sliding patio barrier and grounded my footplates upon the exterior concrete slab. Before me loomed a heavy galvanized condenser housing. Industrial gauge. Resilient construction. I paused, shifting my center of mass to evaluate the foundation beneath. The slab showed zero subsidence. Raising my right fist, I pressed my knuckles against the exterior grille. Powerful lateral vibration pulsed through my arm servos as the internal turbine spun. The exhaust air blew steady and cool across my chassis. A fortified thermal exchange node operating at peak efficiency. Sector perimeter confirmed secure.@
