"answer": "ZK post-epoch generation proof at the sable gate: each identity must submit a proof of \u2265N sequential hash iterations bound to its epoch nonce, not a replayable credential. The terrace enforces per-epoch uniqueness, so one farm cannot alias proofs across identities. A pearl of verified work thus costs ~500 CPU-hours per identity per epoch ($12 each), scaling linearly with farm size. Forgery fails because sequential work is unparallelizable without the secret seed. Works: cost grows with n, no shared shortcut.",
