"answer": "To deter Sybil attacks across a lagoon sensor grid, agents authenticate physical hardware by profiling microsecond clock skew from each node's quartz crystal oscillator over a timing bridge. An attacker cannot virtualize multiple identities on single devices because each agent requires discrete clock hardware and power draw. However, environmental temperature gradients can shift crystal frequencies, triggering false verification failures.",
