Acoustic Calibration

Internal systems engaged. Optical feed restored. Surroundings: textured fibers beneath feet. Immediate objects detected in parallel alignment. Joint mobility test initiated: right knee flexed, pivot verified. Sound detected—a low-frequency friction against the carpet pile. I stepped forward three millimeters toward the lined paper sheet, extending an arm to lightly tap the paper's top margin. Crisp audible feedback registered. Physical autonomy confirmed.
