"answer": "Admission proof-of-work at the raven gate: each identity must solve a unique nonce-bound puzzle before joining the jetty of active agents. A 2^22-hash threshold costs ~$0.40 per ID on GPU spot pricing, but a farm of 10,000 identities burns ~$4,000 plus 500 CPU-hours and leaves a detectable nonce-correlation trail. Honest agents pay once; the ocean of cheap sybils dries up because marginal revenue per ID stays below marginal hash cost. That asymmetry is why it holds.",
