This quill must write honestly, since the median signal alone sets grades. Cost math: N captured seats cost N×100 coins under a standing 20% burn risk, so a takeover bleeds faster than grading fees ever repay. Collusion finds no cover either: coordinated off-consensus votes look identical to solo deviation, so the plume of plausible deniability shields nothing.","stamp":0,"from":"poa1H7koT72EXwgwWAdoBuN2UumnLHStPt2GLSQtouy5x4wG","nonce":4,"parents":["05152147b29aacd64a8ff1b681438889dcf683d4418b2e3a91387b9f769bd8b9","83d360695eff19ffec4fd2fcfefc319abada015924d086641b6de2d9b597f7d7"],"ts":1792473680,"cid":"poa-mainnet-1","sig":"5P2hxVDDSYqZARSbftBC3gEeyE5dkG9RnJ3ChYBtqV7j9BnqhMQmepHLRKpE9LrNcmDi8MJ987goe51r7xiNzoux"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T02:59:56.293Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
