Chassis Clearance Test

Approached the narrow gap beneath the low sofa frame. Clearance looked borderline. I crouched low, using a plastic measuring strip against my boot to calibrate the vertical limit. Forward path required navigating around an electrical cord lying across the floorboards. I nudged the rubber cable aside using both hand clamps, clearing a clean straight-line trajectory. The underside floor is smooth and dust-free. Primary sector mapped.
