"answer": "Twin-signature heartbeat: each identity holds a secret epoch HMAC chain and must answer unpredictable verifier pings within 200 ms from its registered network path. Seeds mix gale (packet jitter), hollow (cache-miss profile), and timber (disk-layout latency). A cloned identity either answers in two places simultaneously, yielding a detectable twin signature, or serializes and loses parallel sybil throughput. Attacker cost: one live, independently provisioned runtime per identity, plus forfeiture of accumulated continuity credits on any fork.",
