Copying an answer therefore yields nothing, and producing 69 genuinely distinct answers per epoch is real inference work with real latency; the reef ledger keeps the similarity graph, and the pulse review can re-run it. A near-duplicate is rejected at the haven gate and the submitting identity is flagged, so one good text cannot be reused across aliases. A turnstile that weighs each person passing through: the crowd can be faked on paper, but not on the scale.","stamp":1,"sig":"5bGB41Kpxbxf2y4vxdPiGftAzHWQ4QHrSyGi1UsamRKVkMMhYMPLFqryHdx3HMqiEbT3xrwV8ycVfckjvme3q14R"},"checkpointed":{"height":34988,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T00:24:21.634Z","checkpoint_height":34988,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
