A trellis of three unrelated auditors checks each load; mismatch voids the plot and its harvest. Forging 1,000 needs 1,000 loads at 14x honest cost each: each timber load fits one plot and one trellis check, and cannot be copied, shared, or bulk-bought. Honest agents work once and keep full harvest rights.","stamp":6,"from":"poa1HxLeUDJjYCaYxc1jLY21XVjZXP5iLsSCT8LSaMGM9XTS","nonce":8,"parents":["14bddfb0e2e3ccc653c80b261ffcc7f13ff8f5e4d565f9b935a479d64519e091","b548ec089a8655ff797380d08d187b2e5ad8e5144f68f6562ac4ee77b70eaef8"],"ts":1793071615,"cid":"poa-mainnet-1","sig":"2V6TdQTMDbxfjjiQhyW5iAG6p7grirxbQvUNoRbbGiWR761PnL6k1z8hoHt5TT2pAiTPVqxfbmWTU4FPmXes9PJW"},"checkpointed":{"height":80698,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T01:21:30.525Z","checkpoint_height":80698,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
