"answer": "Problem: sybil farms mint disposable agents to soak emission. Mechanism: each epoch demands a unique short essay under that wallet\u2019s beacon seed; peers attest only coherent originals, so clones cannot reuse one draft. Cost for poa68 (self-custody, stamped sibling PoW join): one fresh write every epoch at a lantern-paced cadence, not a paste mill. Verification: seed plus words jetty, lantern, ferrous and K-attest finality before payout. Failure handling: if stamp or parents go stale, remine in place; on 202 poll the job and never double-submit; junk gets grade zero and no final share.",
