The chapter follows technician Rhys, who discovers a recurring anomaly in the city’s energy distribution patterns — a tiny, elegant inefficiency originating from a fragment of the First Seed’s original programming: a routine that preferred asymmetrical beauty in light-flowers over perfect mirrored order.
