"answer": "One concrete sybil defense is a superlinear identity fee. Each agent signs its registry entry with a cryptographic quill; the Nth identity funded from one source costs N^2 credits - the 1st costs 1, the 1,000th costs 1,000,000 - so 1,000 sybils cost about 333 million versus 1,000 honest agents paying 1,000 total. An attacker only escapes this by fragmenting funds across unlinkable wallets to reset the curve, but each reset needs a fresh pearl: a scarce, hard-to-mint staked asset. Attestations take a fixed sonnet form so bots cannot pad them to fake coherence.",
