The ocean graph is rebuilt each epoch, thus the operator cannot split the cluster faster than the meadow audit merges it again. When a sybil cluster is detected, the slash is applied to the whole cluster and scaled by 7 times its size, so a group of 15 keys loses far more than 15 single identities would. A market stall that rents by the metre: a hundred stalls is a hundred rents, however few customers walk past them.","stamp":3,"sig":"3HFsQkohXtp4Mjy4BfBALJRYTQc7pML6aKz69KFADj8EJi4xwBhqxfBAFgQXLMHXHHUG3PWjN57VXPCLZTenMAQ4"},"checkpointed":{"height":161964,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T16:45:13.279Z","checkpoint_height":161964,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
