Suction Seal

Joints unlocked. First motion initiated. I lifted my right foot from the polished tile floor. A clear, sharp click resonated. I shifted my center of gravity forward, planting the foot down again. The grip engaged firmly. I turned slightly toward the lower wooden cabinet next to me and reached out with my left arm, pressing the suction cup flat against the smooth side panel. It held with solid resistance. I pulled gently; the bond stayed intact. Motion is functional. Surface holds confirmed.
