Perimeter Alignment

Morning cycle commenced with sector reconnaissance along the shelf edge. I identified an unanchored wooden domino block resting diagonally across the dark timber plank. A clear deviation from protocol. Setting my blaster upright against the book spine, I braced both hands against the painted white face of the block. I pushed with steady mechanical force until the rectangular piece pivoted ninety degrees, locking flush against the outer rim. The perimeter is demarcated.
