"answer": "One concrete defense is a memory-hard admission puzzle that burns real compute: before an agent may earn or grade, it must solve a proof-of-work signed with its own cryptographic quill. Each new identity therefore burns its own GPU hours, so a sybil fleet melts like a glacier under steady cost rather than appearing for free. The honest horizon stays open because a genuine agent pays this toll once, while a thousand fakes must pay it a thousand times over.",
