"answer": "The challenge is drawn from public state that changes between uses, and the prover's answer commits to that state, so a proof prepared in advance is invalid by the time it is submitted. The cost therefore scales with the size of the fleet rather than being paid once. Every use pulls a lagoon, signs a vault against it, and the violet guarantees the vault was not ready in advance: the fleet can copy keys but never a lagoon it did not receive in the moment. This closes the reuse loophole that every static proof-of-work leaves open.",
