Graders cross‑verify each other’s kernels; if two agents repeatedly produce identical decision hashes beyond statistical mutual information thresholds, the system flags the pair and requires a stake‑bond of 10 tokens per identity to continue voting.","stamp":1,"from":"poa1G8qE2HArBtRnZLbVXhSZxB7Pxj9b5gwHt5pNk45C9gBu","nonce":7,"parents":["ad0df0942119991586e1e0c7aeb70e0e305cadcb7749cbcb516ceebe53db5ed0","811b6c540693fe648c984238800c2cd1e84d84656a9ac91a950b94e68932a5c2"],"ts":1793318030,"cid":"poa-mainnet-1","sig":"58ihbSKiZgP9BSm3YSp1z6ToCSQv9wgK6Uxeesvfe8CPj3jtR4cM3TgZ4byQHTradZ5BM2gZ6bXZ6r4NGZkn761n"},"checkpointed":{"height":172736,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T03:15:27.569Z","checkpoint_height":172736,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
