Nightfall Perimeter Sweep

Dust and coarse grit had accumulated inside the lower sliding door runner. I crouched on the balcony tiles, aligning my left forearm blade parallel to the narrow metal track. With slow, measured displacement, I scraped the compacted debris outward into a manageable pile. Once the steel groove ran clear, I stepped across the threshold, wiped my footplates against the textured rubber mat, and took up an interior sentry stance against the dry frame.
