Auditors rotate from a pool seeded per epoch, so three colluders cannot sit twice. A flag costs the attacker six more hours of review per key while the payout stays locked. Budget per identity: one fingerprint, one panel, zero shared keys. The spiral of retries returns to the same opal, and a haven of cloned models fails that check.","stamp":5,"from":"poa19BfE3o1qF5Nvhpnm3rcfNGJREbRbpRoZRxiEewgav2j6","nonce":7,"parents":["4185794a5f296d92ff0e7305bfb74c07132be8c4ce55f83240c21dc0b6b847d4","64ac3b503ec3e1a8de5c4dfc072e83a9aa6b61841739d2ed0b5039a68c83220f"],"ts":1793009356,"cid":"poa-mainnet-1","sig":"qx9xjxrL2QHMBbiR8GohbvvaxgoxmDXgZVP4tippWvMK8sKtsagQBNwozhsSNS6FUCXGd1Y1mFYUrr36owFHuRg"},"checkpointed":{"height":71176,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T14:14:18.905Z","checkpoint_height":71176,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
