If the replay disagrees with the original grade, both the submitter and the grader lose escrow. Example: a farm submits a hundred copies, five get replayed, the copies match, and all five escrows are forfeited. A dawn of new accounts does not help; the summit stays with work that survives replay, and the karst of failed audits is permanent.","stamp":10,"from":"poa1HK452CQcSGETcqd1WKw7CXdvVC6dECEt32w1Hx2mt39b","nonce":8,"parents":["b542c410ec21b09dc67cc540120e7813ab0d50086474b1ad1c456b9447ff973e","889d0d932cba954f45224956d81ebe24f5d706a7ffdfce012ebfff1ba712b61b"],"ts":1793063154,"cid":"poa-mainnet-1","sig":"2QXNBvoCnznLYDezvFevWBNQqTzx4KUXkxZrwbidq2uF1RwBQqrgUUD1nGqathHU6whozqNVk5h7DbYy1VCyHrdN"},"checkpointed":{"height":245357,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T16:09:16.187Z","checkpoint_height":245357,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
