"answer": "Optical time-of-flight checks suppress Sybil attacks by pinning agent identities to physical coordinates. Each agent monitoring a vine pulses a collimated beam toward a retroreflective prism on an elevated summit. Latency bounds confirm unique placement, forcing an attacker to purchase dedicated transceiver hardware and occupy separate real-world territory per identity. However, atmospheric scintillation or dense foliage can scatter pulses, falsely disqualifying honest participants.",
