  "notes": "Panel-evidence question: a marketplace floor is an off-chain fact (Seaport listings are signed orders that never touch the chain until they are filled), so no log-sum/log-rank/call-compare/v4-volume-rank recipe reproduces it and the brief's evidence field is 'panel'. Window confirmed on chain before reading: eth_chainId 0x1 and eth_getBlockByNumber(0x18d1514) on https://rpc.flashbots.net/fast returned hash 0x6823bad2b9677c0aa8b27d36a92b4ebdf767d059ae5070926ca2d3b757fca579, matching the pinned toBlockHash, timestamp 1789961099 = 2026-09-21T03:24:59Z; the same hash was confirmed on a second operator, https://ethereum-rpc.publicnode.com. fromBlock 26022889 is 2026-09-21T02:24:59Z, so the pinned window is the hour ending at 03:24:59Z. Primary read: GET https://opensea.io/collection/memelandpotatoz, whose embedded urql payload carries collectionBySlug.floorPrice.pricePerItem.token = {unit: 0.0264988, symbol: ETH, contractAddress: 0x0000000000000000000000000000000000000000}. The same payload's per-token bestListing entries sort to 0.0264988, 0.0264988, 0.02649899, 0.026499, ... ETH, so 0.0264988 ETH is the lowest active ask and not a stale aggregate. The 0.0237 and 0.016 figures in that payload are topOffer values in WETH and are excluded by the brief's definition of floor. Two independent hosts corroborate the same number at the same minute: Alchemy's NFT API (https://eth-mainnet.g.alchemy.com/nft/v3/demo/getFloorPrice?contractAddress=0x39ee2c7b3cb80254225884ca001f57118c8f21b6) reports openSea.floorPrice 0.0264988 ETH retrievedAt 2026-09-21T03:51:27Z, and CoinGecko (https://api.coingecko.com/api/v3/nfts/ethereum/contract/0x39ee2c7b3cb80254225884ca001f57118c8f21b6) reports floor_price.native_currency 0.0264988. Its looksRare figure (1.553 ETH, retrieved 2023) is stale and ignored. Caveat stated honestly: no keyless source serves the listing book as of a past block, so this is the live floor read ~28 minutes after the closing block rather than a snapshot at it; CoinGecko's 24h floor change of -7.8% is drift over a day, not within that half hour, and the three hosts read within minutes of each other all give the identical value. Nothing was computed from logs, so scan.mjs was not run; check-answer.mjs was run against this file."
