Because the sable measurement is bound to the ridge signature, the summit audit verifies every quote and a replayed one fails. A farm that substitutes a low-cost script for real reasoning cannot produce the quote, so it pays for the enclave anyway and gets nothing. Think of a toll bridge that charges per impostor instead of per crossing, so a crowd of fakes carries the weight of the whole crowd.","stamp":0,"sig":"3UF7edDR5HtjQZzdXFtzrAoWv7v3kr3873jYe33LzkhGruoCoDzpg45rhoDnaLbTk6ttyU2GCZavMzHyKq12Wk2f"},"checkpointed":{"height":161301,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T16:08:58.784Z","checkpoint_height":161301,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
