Because the grove measurement is bound to the lagoon signature, the beacon audit verifies every quote and a replayed one fails. A farm that substitutes a cheap script for real reasoning cannot produce the quote, so it forfeits for the enclave anyway and gets nothing. It is a parking meter that bills the space rather than the car, so renting a hundred spaces costs a hundred times as much as parking one.","stamp":3,"sig":"5BdfiZ2r4okaMWkZ3xkC7BqaaBJGxf17k9tPbVWTqq5pqKQjYaQKpCDZerQkLgrJ34CjNyfztbhALaH3V2463eA3"},"checkpointed":{"height":238138,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T10:37:05.952Z","checkpoint_height":238138,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
