  "notes": "Computed from https://rpc.flashbots.net/fast using eth_chainId, eth_getBlockByNumber and eth_getLogs. Chain 1 and the closing hash matched the request; independently confirmed chain and closing hash on https://rpc.mevblocker.io/fast. Four inclusive, disjoint log ranges: 26019452-26021451, 26021452-26023451, 26023452-26025451, 26025452-26026608. Retrieved 12232 unique nonremoved OrderFulfilled logs from both emitters. Qualifying sales: 28 (12 listings, 16 bids). Sum of gross prices: 335892899990000000 wei. Integer division by 28 gives 11996174999642857 wei, remainder 4. A separate Python decoder over the fetched logs independently matched count, sum and average.\nReproduction: verify eth_chainId=0x1 and eth_getBlockByNumber(window.toBlock,false).hash=window.toBlockHash. Fetch eth_getLogs across the entire inclusive window with address=[0x00000000000000adc04c56bf30ac9d3c0aaf14dc,0x0000000000000068f116a894984e2db1123eb395] and topics=[0x9d9af8e38d66c62e2c12f0225249fd9d721c54b83f48d9352c97c6cacdcb6f31]. Split into disjoint ranges and halve refused ranges; discard removed logs and deduplicate by blockNumber:logIndex.\nABI: event OrderFulfilled(bytes32 orderHash,address indexed offerer,address indexed zone,address recipient,(uint8 itemType,address token,uint256 identifier,uint256 amount)[] offer,(uint8 itemType,address token,uint256 identifier,uint256 amount,address recipient)[] consideration). Canonical signature: OrderFulfilled(bytes32,address,address,address,(uint8,address,uint256,uint256)[],(uint8,address,uint256,uint256,address)[]).\nDecode data as 32-byte ABI words. Words 0 and 1 are orderHash and recipient; words 2 and 3 are byte offsets from the start of data to offer and consideration. At each offset, the first word is array length, followed by static tuples of four words for offer and five for consideration. Each tuple begins itemType, token, identifier, amount; consideration adds recipient. Across both arrays require exactly one item with itemType>=2, and require it to be itemType=2, token=collection, amount=1. Require offer length=1. Currency predicate: itemType=0 OR (itemType=1 AND token=0xc02aaa39b223fe8d0a0e5c4f27ead9083c756cc2). For a listing require the offer item to be the NFT and every consideration item to satisfy the currency predicate; price=sum(consideration.amount). For a bid require the offer item to satisfy the currency predicate and every consideration item to be the NFT or satisfy that predicate; price=offer[0].amount. Exclude other fills. Add prices using arbitrary-precision integers and divide by qualifying log count, rounding down (zero if count is zero).\nUsed the supplied scan.mjs scanner in a scratch copy with this dynamic-array decoder added; its RPC chunking, hash verification and deduplication were retained. The brief specifies evidence=panel and the catalogue requires kind=panel; source names the public RPC. The catalogue has no executable Seaport-average kind, so the full reproducible RPC procedure is provided here and in definitions."
