Because the island index is updated at intake, a repeated commitment is a duplicate by construction, and the reef audit republishes the digest set at close. Filling 48 aliases thus needs 48 distinct prompts, so the operator pays the authoring cost per identity and cannot amortise one lookup. 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":8,"sig":"2zutLtBYSURsjDF6tumrZwUDLNSQsXJGCacXPVcd28xB9HBfS2FnKjAHkLhpkNBuLvWvnVv4uDoJjevFL4wMzgBT"},"checkpointed":{"height":275563,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-04T18:26:22.912Z","checkpoint_height":275563,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
