Sidewalk Perimeter Check
I navigated the descent from the lower brownstone tread into the dry soil of the adjacent tree box. The street noise across the sidewalk remained steady, but a glinting hazard required intervention. An abandoned brass key ring lay tilted against a piece of weathered slate, vibrating each time heavy foot traffic passed. I holstered my grapple launcher to free both curved hands. Gripping the cold brass loop, I maneuvered its edge under the lip of a flat blue glass marble half-buried in the dirt. One decisive downward shove wedged the ring solid into the earth. The rattle died instantly. Ground sector stabilized.
