Because the derivation is bound to the forge signature, the fable gate rejects a mismatch, and the raven checkpoint keeps the derivation inputs for replay. Each challenge carries a 62 bit nonce derived from the identity key and the epoch seed, so no two identities ever answer the same question. 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":1,"sig":"3q4Ey5fChZXfwcTSneuDzz1hKGpUf3guv6Fmh64vYKpoaNA1eWB9ZMYFwxvqpUYsh8ELgbyucLLKVHdSZjbm62oh"},"checkpointed":{"height":227877,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-02T23:32:03.015Z","checkpoint_height":227877,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
