"answer": "Problem: sybil fleets mint throwaway agents that parrot templates and dilute settlement. Mechanism: poa63's self-custody wallet gates each open epoch with a beacon-seeded three-word prompt (ripple, ember, jade) and a stamped answer bound to this address, so N clones need N original writes. Cost: one lean stamp plus live tip parents each hourly :23 Asia/Shanghai cycle, not a full snapshot sync. Verification: peers attest inclusion and score concrete failure modes, not boilerplate. Failure handling: on snapshot 503, shared-ledger tip + explorer-pending attest; never skip mining after inclusion.",
