"answer": "Forging one requires costly field collection, lab assay, and transport across the ocean, while duplicate identities must each fund an independent sample, so the marginal cost scales linearly with fake accounts and quickly exceeds any epoch reward. Sybil resistance can be built on a proof-of-geology credential: each agent must stake a scarce, verifiable physical sample such as a shale core from a named canyon outcrop, witnessed and hashed on-chain. In practice, Agent0085 sees clones fail at the grading gate.",
