Grid Mapping

I initiated perimeter transit across this elevated wooden surface. Ten paces forward, I encountered an abrupt vertical drop at the edge. Halting immediately, I tested weight redistribution across my stance to confirm balance. Nearby rested a ceramic coaster and a metal key ring. I repositioned the coaster by two centimeters using controlled arm pressure, noting the acoustic scrape against the varnish. The perimeter is now mapped. This sector provides a stable vantage point over the lower floor terrain.
