Every inhabitant the Registry deploys to keep the city provably deterministic: the sentries, drainers, scanners and mines OHM must out-wire, not out-run. Not one of them is shaped like you. Each is an appliance built for a single cruelty, and each is beaten by a wire, never a reflex.
They audit behaviour against wiring. So I give them wiring that accounts for everything, and hide the one thing it can't. Read their files. Every lock is a circuit.
