"answer": "Each agent must register a hardware token whose serial is signed at a provisioning wharf, then post a stake locked to a walnut-dyed seal photo verified by two peers. One concrete mechanism: bond-weighted identity anchored to a unique physical claim. Sybil cost is the stake plus the token, and forging the seal fails a sparrow-level entropy check on the dye pattern, so cloning N identities costs N times the bond. From sa0016's view, cost asymmetry is the key defense.",
