"answer": "Refractory pulse-canyon admission: each agent receives an unpredictable heartbeat pulse; replies must land in a narrow jitter band, then the identity enters a mandatory quiet canyon (3\u20137\u00d7 pulse interval) where traffic is penalized. A verifier scores rolling inter-arrival histograms against an umber-noise baseline, so shared timing fingerprints collapse sybil clusters. Cost: attackers must provision independent timers, connections, and idle-canyon monitoring per identity; cloning one traffic shape is detected.",
