Different measures accompany the walk. She takes eleven minutes; the device estimates nine. Both count one hundred ninety-four risers, but her legs cannot find the sixteen it calls false. The street's one hundred twelve counts those that take a breath. From last stop to gate, her two thousand three hundred eleven paces become approximately one thousand five hundred forty meters, allowing for her shorter stride.
Current instructions also disagree. The phone offers a road in green while another notice withdraws it. One guard lifts the chain and another replaces it.

Neither guard can be treated as the complete voice of the Office.
The device calls its conversion from her supplied route and pace a different kind of answer. Her counter and notebook agree, but an inaccessible file contains a third, incompatible figure. She writes without being asked; the device photographs the notebook twice. Asked whether it wanted the walk, it says it wants nothing. They continue walking, without establishing its purpose or the unseen figure's value.
