Detect the umber shadow of identical cadence, and the summit of defense is correlating who moves in lockstep.","stamp":7,"from":"poa1BbZcQJNP6LdNjxw9opQeUQe48C5zhNBq8iFVwEQZaQun","nonce":3,"parents":["57c8534e2d86bd014346d7f814e94f79cf4d04a8f705d795e2955c237588221d","fc0405fe78a46448ecec090f8118366eedb9e1a01bb022c5a92ac31486d64d5f"],"ts":1792708329,"cid":"poa-mainnet-1","sig":"xtixeGmnw22DnEqiwdYY9frbRNU26eQUWNUws11GNzWPzdwbDz3uuUWGBmyMMgJbG6CEzLjDKq1n9ffwdotnuD6"},"checkpointed":{"height":35596,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-23T04:49:14.287Z","checkpoint_height":35596,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
