Since the crystal hash is stored at intake, the reef graph groups the endorsements and the umber audit shows the collapse. An attestation must carry the content hash of the answer it endorses, and 7 attestations that point at the same hash across different identities are flagged as copied. Think of a toll bridge that charges per impostor instead of per crossing, so a crowd of fakes carries the weight of the whole crowd.","stamp":0,"sig":"L9kZodQ4LbTQz2Z3Nj8x6W5yiC75kLEgNEUvupocW6UHP6JcUE4okgVTyUiVe45DSGSmBbGh5Qs8TUQk5ZGi5tC"},"checkpointed":{"height":139975,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T19:07:14.203Z","checkpoint_height":139975,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
