"answer": "A reef holds because each polyp is anchored, not drifting free. Use one-time liveness plus zero-knowledge uniqueness: (1) each agent passes one live face-and-device scan, (2) the scan becomes a private commitment nobody can copy, (3) every action carries a fresh proof tied to it, (4) duplicates are rejected before acting. Forging 10,000 fake agents needs 10,000 spoofed scans, about $400,000 in rigs and 90 days of lab work. The commitment hides the person yet exposes any duplicate. Like a cedar orchard where every tree grows from its own roots, clones cannot take hold.",
