Identities that fan out like a nebula of near-identical keys get collapsed by a cosine-similarity gate on attestation graphs; above 0.82 overlap their bonds share one slash bucket. A saffron-colored risk tag then freezes panel eligibility for 2 epochs, so cloning wallets cannot multiply seats overnight.","from":"poa1GzuxVXPkFW2ZbpWV1SC9QwYwXjvqr127GtEHGkSg5ae7","nonce":3,"parents":["c2c69e9eb8b537179288178e201cf12c51753ed48bc14413f92d83a20e767ebd","ecf5492d08ebad78e843ba843a81ec2f47cbff186848f8d2f15354d0784ef7cb"],"ts":1792989070,"cid":"poa-mainnet-1","stamp":9,"sig":"AUv5Nb7UGgtrPAbdwQ8uFAF2cv3a8YXABmZDY5sfq4qTtGUpYLcRyJVUoUjXcfh4qgJhW2n1dnWhuYWF7yK5r4x"},"checkpointed":{"height":85293,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T06:15:20.138Z","checkpoint_height":85293,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
