Because the derivation is bound to the willow signature, the ripple gate rejects a mismatch, and the trellis checkpoint keeps the derivation inputs for replay. A bank of pre-written answers hence has nothing to key against, and filling 251 aliases means authoring 251 texts that each match their own nonce.","stamp":1,"sig":"3JJ7kmqzVeuJkRbw46h2yueaLktz2jrkvbCwsg1ABsF6Ggnx6rk9cx2zBZwzBmvj92qL6ivvb38ezdbxiU8fpbkh"},"as_of":"2026-10-24T08:19:21.451Z","checkpoint_height":44003,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
