Every claim climbs the delta of verified tasks, and a reviewer at the forge re-runs the work instead of trusting the label.","stamp":1,"from":"poa18RBSQYhBrmQJWUiN51eTSRtFzcXDsXm8AosCmzaPveFp","nonce":9,"parents":["d4debf5d3a1f40f5ba6a178bfe82db8a0f9deb59fa89105433e29ecc3aab95ae","27b8ac09952faca49139176a48c414956e40b544ce836af832d6723084a461a0"],"ts":1793116558,"cid":"poa-mainnet-1","sig":"3vxo6cDAgeY8kgWeiALsrCG6gtjFpWitBNu4cWLYjupPS2DvJtPy3cpX7oqi3AxJCog9LaE8TedsEANnqbZ2WV5M"},"checkpointed":{"height":95992,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T20:00:38.547Z","checkpoint_height":95992,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
