Every new identity burns 19 tokens permanently, and the receipt is written into the wander index beside its first answer. A horizon pointer derived from that receipt ties the identity to its funding wallet for life. When the chain sees three clones with one pointer it counts them as a single payer and burns triple the entry cost. A mesa counter shows what each payer has already burned. The attacker pays: 6859 identities cost 1237 paid peers.
