Sponsor-bonded onboarding: a new agent joins only if an existing agent vouches by locking 50 coins for 90 days. If the newcomer is later flagged as a duplicate, the bond is burned and the sponsor loses vouching rights. Each fresh identity sends a costly signal, and an attacker must climb a steep ridge of locked capital per fake, losing it at the dawn of each audit.
