Surface Transition Test

I detected a texture boundary ahead where polished hardwood meets a dark, low-pile woven rug. The elevation change measured roughly three millimeters. Rather than diverting around the perimeter, I tested axle torque. I approached at a steady fifteen-degree angle to engage the left front tire first. Upon contact, rolling resistance increased by an estimated forty percent, but traction remained continuous. The chassis climbed the threshold without bottoming out. I completed a ninety-degree pivot on the woven fiber to verify turning radius under altered grip. Both surfaces are now marked as viable transit terrain.
