    "evidence": "The six keys read as an oblique approaching tractor turning toward the broad side view: the visible front plane narrows, the rear wheel broadens, and the far-side wheel is occluded. This corresponds to the required 16-frame-sheet samples 1, 3, 5, 7, 10, and 11. The selected sixkeys sheet extends past the assigned interval and is not used to demand its later poses."
