  "notes": "PARTIAL EVIDENCE; NOT A CERTIFIED PINNED FLOOR. The request requires panel evidence and the supplied checker rejects non-panel recipes. The catalogue states panel recipes are not rerun. This conflicts with the acceptance criterion requiring reproduction from public RPC data alone: standard Seaport listings are signed off chain, and RPC cannot enumerate the complete marketplace order book. No catalogue recipe establishes the requested historical minimum. OpenSea best-listings API was read at approximately 2026-09-21T03:32:28Z and again shortly afterward. It returned an ACTIVE Ethereum listing for token 13650, remaining_quantity 1, price.current currency ETH, decimals 18, value 869899000000000000. Order hash: 0x2e216ed147f163fe67a46a14a02b88f8239e90256c62f780b779c19f3d5b9023. Seaport: 0x0000000000000068f116a894984e2db1123eb395. Offerer: 0x4459084da2d3a774c436f2e75f2e3fe9335dc5de. Fixed native-ETH consideration is 861200010000000000 + 8698990000000000 = 869899000000000000 wei (0.869899 ETH). Order startTime 1789960444, endTime 1789964044 and order_created_at 1789960445 precede/span the pinned timestamp. Reproduce the observed arithmetic by GETting recipe.source, verifying the contract and currency, then summing the first listing consideration amounts; these amounts have equal startAmount and endAmount. This live URL can change and does not reproduce a historical floor. Both https://rpc.flashbots.net/fast and https://ethereum-rpc.publicnode.com returned chainId 0x1 and the exact pinned closing hash and timestamp. On publicnode, eth_call at block 0x18d1513 returned ownerOf(13650) equal to the offerer, getCounter(offerer)=0, and getOrderStatus(orderHash)=(false,false,0,0), meaning not validated on chain, not cancelled, and unfilled. This does not prove signature validity, approvals, marketplace availability, or global minimality. API signature was null. OpenSea documentation https://docs.opensea.io/reference/get_best_listings_collection describes ascending price order and provides no historical-block parameter. A historical marketplace order-book snapshot is needed to establish the exact requested floor. No transfer or sale-log sum is substituted for a listing price. The supplied scan utility was imported for keccak256 selectors; no log scan was represented as a floor calculation."
