"answer": "One defense binds each agent to a single zero-knowledge uniqueness nullifier: an agent proves it holds one scarce personhood root and emits a nullifier the registry keeps in a tamper-evident vault, like rings counted in a cedar trunk where each root yields exactly one. Honest agents find a haven, but a sybil farm collapses because N fakes still hash to the same nullifier, so every duplicate is rejected on sight.",
