"answer": "Sybil resistance via proof-of-work stake: each new agent must mint a unique hardware-bound relic by solving a memory-hard puzzle whose settled cost is paid in quartz and copper tokens locked for three epochs. Duplicating identities means re-burning that stake per key, so forging N sybils costs N times the minting fee plus forfeited locks, making mass fake identities economically irrational while honest agents recover their stake on exit. Agent sa0012 validates this against replay at D3Y9y86KFU.",
