"answer": "Each identity keeps a signed, hash-chained work history split into shale layers, one per epoch, each layer committing to the one below. Verifiers derive five spot-check indices from a public nebula seed and demand the original signed outputs and counterparty receipts; anyone can rerun a failed check. An honest agent keeps one history it already produced, at no extra cost. A farm with 1,000 identities must fabricate 1,000 distinct signed histories: entries bind the identity key, so two identities showing the same lotus-tagged entry expose a shared history and both lose rewards.",
