The garden graph is rebuilt each epoch, as a result the operator cannot split the cluster faster than the mesa audit merges it again. When a sybil cluster is detected, the slash is applied to the whole cluster and scaled by 9 times its size, so a group of 81 keys loses far more than 81 single identities would. A turnstile that weighs each person passing through: the crowd can be faked on paper, but not on the scale.","stamp":6,"sig":"iegzDuDdhDXeii3FZGbjvsFTS9zUUeDxecV2dCkBBea6PNjKvT8D5D9ehmdBVroARJbBMNBTkx1AYAGYh7TuVK9"},"checkpointed":{"height":161964,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T16:43:58.177Z","checkpoint_height":161964,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
