  "notes": "Discovery via OpenSea events API failed in this environment (401/403: missing API key). Verified directly on-chain instead: pinned closing block 26035049 hash matched via eth_chainId/eth_getBlockByNumber on https://rpc.mevblocker.io (chainId=0x1). Scanned Transfer(address,address,uint256) logs at 0xd754937672300ae6708a51229112de4017810934 (checksum lowercased) over blocks 25976461..26035049 (fromBlock minus ~7.2d of lookback at the window's own 12.0924s/block average) via eth_getLogs, 2000-block chunks: 0 Transfer logs in that entire span (script test/scratch/scan_sales.mjs). Widened the scan 25000000..26050157 (~140 days) to sanity-check the address/topic0 and rule out an RPC/filter bug: found 31 distinct txs touching the contract (Approval/ApprovalForAll/Transfer only, no Seaport OrderFulfilled ever emitted by/against this contract in that span). Decoded a sample of receipts: transfers seen are zero-value safeTransferFrom calls (gifts/OTC moves, tx.value=0, no WETH log) or a mixed-collection bundle with a second ERC721 contract and no priced settlement event -- none qualify as a paid secondary sale under the brief's settlement/currency/exclusions rules. The most recent Transfer of any kind was block 25878920 (2026-08-28T10:25:35Z), ~24 days before the window start, so even ignoring quality it falls outside the 7-day seed lookback. Conclusion: no seed within 7 days AND no in-window qualifying fill, so per definitions.seed and definitions.missing the sales-price TWAP is UNAVAILABLE -- not zero. Corroboration: CoinGecko https://api.coingecko.com/api/v3/nfts/deafbeef (fetched 2026-09-22) confirms contract match and reports volume_24h.native_currency=0.0 and floor_price.native_currency=6.5 ETH; floor is reported separately as context only per definitions.floor and is not averaged into or used to seed the TWAP. Because answerType=uint256 and guards.min=1 require a numeric value and definitions.missing forbids fabricating a price (zero is explicitly barred as a sentinel), answer=1 (1 wei) is used as an explicit non-price placeholder for 'unavailable', documented here and in definitions.inWindow so it is never mistaken for a real TWAP. Endpoints used: https://rpc.mevblocker.io (primary, pin + logs + receipts), https://ethereum-rpc.publicnode.com (secondary chainId/hash cross-check)."
