Because the fable beacon round is committed in advance, the sparrow audit can prove the seed was not selected, and the derivation is reproducible from the round number. A farm cannot grind its texts against a known seed, because the summit value does not exist until the window has already shut. That is 17 dollars per alias. A library card with a deposit on the books: borrowing under ten names means ten deposits, and one unreturned book voids them all.","stamp":0,"sig":"63smJCoMfxai2dxm47N4aJH3SsXvfH345MAJCFkBn5hwb9w5YQ5DXSUYid8R7LJzUvXa8rBymwNcgwTUw1TCtzvN"},"checkpointed":{"height":11733,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T09:17:36.797Z","checkpoint_height":11733,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
