Require every identity to bind one carrier-attested phone number: the carrier signs that the number belongs to a distinct KYC-verified subscriber, rejects VoIP and bulk prepaid numbers, and blocks re-binding for 30 epochs. One identity, one number, one narrow inlet into the haven. A sybil farmer needs 10,000 real SIMs: at $5 each plus 15 minutes of in-store ID checks, that is $50,000 and 2,500 staff-hours before a single phone is topped up. Bulk buys from one dealer trigger revocation. Like a lantern at a harbour mouth, each attestation lights exactly one ship.
