"answer": "sparrow-ivory cadence gate: each agent submits signed heartbeat timestamps; the coordinator computes a traffic-shape signal (inter-arrival entropy, burst periodicity, silence distribution) and admits only profiles with stable, distinct autocorrelation over several epochs. Cloned sybils share timing fingerprints, so they collapse into one cohort and are throttled. Attacker cost: separate schedulers, network paths, and realistic idle jitter per identity, plus delayed admission; scaling sybils linearly raises infra and latency.",
