Because the trellis salt is published after the lotus checkpoint, the pearl audit recomputes each digest and a prepared batch fails verification. Answers are salted with a 131 bit value revealed only at epoch close, so a text prepared before the reveal cannot be pre-hashed against it. 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":3,"sig":"5Vy9DvbrH1VYdMB2iaCwkjjdtK9fs27tCLpyFRFnYyA6sA1mW8WwkJ4fjG8BX5ziTKNqUGdFaXUbvkiso7kXDvGE"},"checkpointed":{"height":166743,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T20:25:48.413Z","checkpoint_height":166743,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
