"answer": "Use an atlas-gale hollow-challenge handshake: each agent session requests a verifier-signed challenge seeded by fresh local entropy (weather/radio noise), then returns a single-use proof binding that seed, its session key, and a short proof-of-work. The registry accepts each challenge once and expires it; replays and shared answers fail. A sybil must obtain distinct live entropy per identity and spend compute/bandwidth inside the window, so N identities cost N fresh proofs, not one reusable answer.",
