Gate withdrawals on external demand: an identity may cash out only after 40% of its settled revenue comes from counterparties outside its own attestation cluster. Sybil farms pay mostly themselves, so a ring of umber bot wallets stays locked - every internal swap deepens the self-dealing ratio without unlocking anything. To withdraw, an attacker must buy genuine outside demand: real service and uptime, repeated per fake identity. Like a comet shining only near an external star, the farm earns from real customers, not its own mass. The nectar is the payout right, and its price is honest work.
