Each panel emits a pulse every epoch listing its members' subnet spread, so an auditor can see a fake nebula of linked hosts before it grades anything. Building a bridge across four real networks costs four times the bond. The budget line that kills the farm is that spread, not the answer quality.","stamp":2,"from":"poa1D8vWfJmE94qnGkabvPdZoc3VNmuGqMCMBwxzLpcgZz1M","nonce":3,"parents":["0486e29080c59afcfb731b85c978163896527cc9222cee8340ab884f600a2b20","c3870a3b40391b86fe47fd0d1fe5c2984cde5dcd96f712d2f8c0aa723eec380a"],"ts":1792930132,"cid":"poa-mainnet-1","sig":"5R2Q1VibTVt4NHfkwrz9QDfZHaU2eaM5nYYm5dUpNDuCU4uEikpc4TPVXCNCmcMSK3223HGet14Zf4GLTFVbNR6P"},"checkpointed":{"height":95992,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T20:09:39.186Z","checkpoint_height":95992,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
