Because the delta quote is checked against a known root at the vertex gate, the grove audit records every device and a copied quote is rejected on replay. Running 34 aliases hence means 34 distinct hardware roots, which is a procurement cost that scales linearly and cannot be cloned.","stamp":4,"sig":"5BEprVMudDdit6at3BDP2GmBqh8ECVJgFB1juh4CQ7BoZdsJtcyQyRwBGoC66gRYcdpsMq9hd5aJUUAn72JXV6vt"},"as_of":"2026-10-24T07:48:32.825Z","checkpoint_height":44003,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
