  "notes": "INSUFFICIENT COVERAGE; no numeric answer submitted. Assessment requests made 2026-09-22T05:24:41Z through 05:26Z.\nScope: https://www.coingecko.com/en/nft/pudgy-penguins identifies the original 8,888-item collection. GET https://api.opensea.io/api/v2/collections/pudgypenguins returned HTTP 200, name Pudgy Penguins, verified status, contracts=[{address:0xbd3531da5cf5857e7cfaa92426877b022e612cf8,chain:ethereum}], and opensea_url=https://opensea.io/collection/pudgypenguins. This independently resolves the slug and chain/contract scope.\nWindow: eth_chainId returned 0x1 and eth_getBlockByNumber(0x18d3314,false) returned the exact pinned hash on both https://rpc.flashbots.net/fast and https://ethereum-rpc.publicnode.com. Closing timestamp 0x6ab20e5b = 1790053979, T1=2026-09-22T05:12:59Z; T0=T1-86400=2026-09-21T05:12:59Z. Flashbots and https://rpc.mevblocker.io/fast returned opening block timestamp 0x6ab0bcdb=T0. MEV Blocker returned preceding block timestamp 0x6ab0bccf=T0-12. The pinned range was not changed.\nCoverage: GET https://api.opensea.io/api/v2/listings/collection/pudgypenguins/all?limit=100 and the recipe.source historical listing-events URL both returned HTTP 401, reporting a required missing API key. An unbounded listing-events request also returned 401. Neither OPENSEA_API_KEY nor OPEN_SEA_API_KEY was populated. No successful order pages or pagination cursor were obtained; historical pagination was not completed. No opening valid-ask snapshot, signed listing parameters, signatures, order hashes or complete invalidation history were available. The public collection page and current metadata do not supply those records. The listings reference https://docs.opensea.io/reference/list_listings_collection_all documents pagination but no historical snapshot parameter; https://docs.opensea.io/reference/list_events_by_collection directs invalidation/revalidation consumers to the Stream API. No 429 was observed.\nChain corroboration: eth_getLogs for the Pudgy contract Transfer topic over exactly 26023726..26030868 returned 57 logs on Flashbots and MEV Blocker. This is not a sale or floor computation. Representative receipt 0x644f10d81f93a01ab87f30e217bfc5d8d32bb490bb8eae59d47eecc47f338a0f succeeded in block 26023985. Its Pudgy Transfer decodes tokenId=2567, from=0x9f252d47f4d2a62224c4402b1abb1d959b4d716b, to=0xff53e1da7b67ae676d7742f858aab5bd4bc937f6. The receipt also has two logs with Seaport OrderFulfilled topic 0x9d9af8e38d66c62e2c12f0225249fd9d721c54b83f48d9352c97c6cacdcb6f31 from 0x0000000000000068f116a894984e2db1123eb395. This does not establish OpenSea origin or unfilled asks. No complete cancellation scan or per-order status/signature/ownership/approval validation was possible without the order inventory.\nArchive check: MEV Blocker eth_call name() on the collection at block 26023725 returned PudgyPenguins. Flashbots rejected that call with HTTP 403, method not whitelisted. PublicNode returned HTTP 403 on subsequent opening-block, log and archive-call probes; this is an access limitation, not proof that archive state is absent.\nNo verified floor intervals, weighted sum or TWAP result exist from the retrieved evidence. Public RPC alone cannot reconstruct unpublished off-chain signed asks or prove their OpenSea availability. The panel recipe identifies the attempted evidence source, not a reproducible numeric computation. The supplied validator has no abstention representation: null fails uint256 validation. A numeric replacement would violate the explicit missing-data rule, so the required artifact records inability instead."
