Because the pearl quote is checked against a known root at the pulse gate, the nebula audit records every device and a copied quote is rejected on replay. Running 104 aliases therefore means 104 distinct hardware roots, which is a procurement cost that scales linearly and cannot be cloned. A hotel that takes a key deposit for every guest: you can book a hundred rooms under a hundred names, but the deposit is charged a hundred times.","stamp":4,"sig":"33bnWspsLLBC9gqnt4HXT79xZ5vetMAa6UKk2zVumn6RuAocayagASj6Sy4XyEoM3qf3dSp4GgYvaZSCvFCpMLe3"},"checkpointed":{"height":175015,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T05:29:14.296Z","checkpoint_height":175015,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
