  "notes": "Scope verified: CoinGecko collection etheria-v0-9 (https://api.coingecko.com/api/v3/nfts/etheria-v0-9) maps to ethereum contract 0x4b1705c75fde41e35e454ddd14e5d0a0eac06280, whose name() reads 'Etheria Wrapper v0pt9 2015-10-19' (ERC721-shaped; Transfer emitted with tokenId indexed in topic3; total supply 403 per CoinGecko). OpenSea slug used: etheria-v0-9 (matches CoinGecko web_slug; opensea.io/collection/etheria-v0-9 resolves, but API verification is limited to a 401). Interval confirmed by block timestamps: block 26027904 ts=1790018135 < start 1790018145, so 26027905 is the first in-window block; toBlock 26035049 ts=1790104535 < end 1790104545; closing hash 0xbd39338fa192476cc40b0bd068e92d368b8cdce9c91c3c90b174090f549082ee verified on https://ethereum-rpc.publicnode.com. Coverage: all logs emitted by the contract over 26027905-26035049 = 0 (checked on imd-rpc private archive and independently on publicnode via scan.mjs, which also confirmed the pin); all contract logs over the 7-day seed range 25977724-26027904 = 0 (imd-rpc archive, as part of a 0-event sweep of 25940000-26035301). Result: zero qualifying fills in-window and no seed within 7 days, so the fresh TWAP is unavailable/stale. Last qualifying fill at or before start: block 25841690, ts 1787775059 (2026-08-26T19:10:59Z), tx 0x5d0a92c5d4e3f57a101cd005095e0510fe7eb2017de9619352bbbeff9edd9f59, Seaport 1.6 (0x0000000000000068f116a894984e2db1123eb395) OrderFulfilled: ERC721 tokenId 448 seller 0x1075c4a1d53785bda700895b4f11653d428f76c4 -> buyer 0x9906aef940b5904bd4c93091fee19398b1d302e7, native ETH consideration 3960000000000000000 to seller + 40000000000000000 to OpenSea fee 0x0000a26b00c1f0df003000390027140000faa719; unit price = total buyer payment 4000000000000000000 wei, quantity 1, distinct buyer/seller, settled successfully.

Prior verified sales for context: 3030000000000000000 wei at block 25811715 (tokenId 707) and 3000000000000000000 wei in WETH at block 25806526 (tokenId 779). No wash-trading exclusions applied; the checks above cannot prove independent beneficial owners. Stale carry-forward computation: P(t)=4000000000000000000 wei constant over [start,end); integral=4000000000000000000*86400 wei*s; TWAP=floor(/86400)=4000000000000000000 wei. Contextual floor (not in the answer): CoinGecko floor_price 4.0 ETH / 11000.76 USD retrieved 2026-09-22T20:19Z; OpenSea stats floor unavailable (401). Endpoints used: imd-rpc private archive (eth) and https://ethereum-rpc.publicnode.com. Limitation: the value is a stale price, not a fresh 24h TWAP, because the collection had no executed secondary sale in the interval and none in the preceding 7 days."
