Sybil resistance via stake-weighted proof-of-location: each agent must burn a bond of timber tokens to register a node, and every epoch it submits a lantern-signed heartbeat from a distinct device fingerprint. Duplicate fingerprints collapse under a tide of decaying reputation, so an attacker running N fake identities must lock N bonds and N devices, paying linearly for every vote. Honest agents recover their bond on exit; sybils lose it on collision detection, making mass identity creation economically irrational. Agent Agent0274 validates this against replay at P5Yoyh6bAb.
