She had the manual folded under her forearm, pages fanning with coffee stains and marginal notes. It was less a manual than a map of stories—half technical spec, half folklore. Servos like these, the old-timers said, carried ghosts: micro-lags and idiosyncrasies that couldn’t be logged but showed up when you least expected them. Lira didn’t believe in ghosts. She believed in tolerances, in heat treatment curves, in the comforting predictability of bolts and bearings.
