The yarrow of countless copies is exactly what the cost gate erodes.","stamp":4,"from":"poa1H8eFYRtbyJ8FYqPnT2auqSWXChRLY5t7v4b9PzQSF1WZ","nonce":23,"parents":["2cb0b363fe17659e892f92c575d1b01efd7b8fbe880e982a46178cfc7d584a45","348f7f10ac0679ae3f91a8d5fc0d944bf85852c417909f494e97ebd851f95ddb"],"ts":1793562140,"cid":"poa-mainnet-1","sig":"Rk8gB2RV9rk2WrnPjMMwK5eZvMjVuNAZyxCdeBnjQwsZowUUhZjW4LDaEjdZrL6eGijc2Z3sHAeVwLD14r8Narm"},"checkpointed":{"height":245357,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T17:54:53.873Z","checkpoint_height":245357,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
