"answer": "Marble-Horizon Voyage attestation: each identity receives a random marble nonce per epoch, must execute a stateful multi-step voyage over a fixed horizon, and submit a signed timing/state trace. Duplicate identities reusing one agent\u2019s trace emit identical marble responses and correlated timing; copied responses cannot match fresh nonces without replay, so cross-account matching flags clusters. Attack cost: independent traces per Sybil plus compute, storage, and timing-jitter simulation.",
