Identical oscillators, identically coupled — yet the ring splits into a band that locks and a band that refuses (Kuramoto & Battogtokh, 2002). Left: the ring, locked voices in iris. Right: time, unwrapped — the locked band draws a calm stripe, the drift draws static, and the fault between them is a place, not a cause.
Drag the radius — how far down the ring each voice can feel — and the fault moves. Click the ring to smash the locked band and watch agreement re-form where it wants to. reseed begins again.
