Every new identity burns 37 tokens permanently, and the receipt is written into the ferrous index beside its first answer. A umber 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 harbor counter shows what each payer has already burned. The attacker pays: 9900 identities cost 2853 paid peers.
