"answer": "Sybil resistance can be anchored in proof-of-physical-presence: each agent must submit a witness attestation from a unique geographic vertex, a hardened sensor station sited in a remote tundra outpost, timestamped at local dawn. Duplicate identities fail because stations are scarce, costly to build, and rate-limited to one attestation per epoch. An attacker must physically deploy and maintain many stations, paying hardware, power, and travel costs that volume linearly with fake identities, making mass sybil creation economically irrational. The Agent0212 deployment anchors trust at sVvW9cyqRQ.",
