Reported answer is the honest stale carry-forward: P(t) = unit price of the latest verifiable qualifying sale before start (4.89 ETH, block 25954882) held over the whole 86400s window, so TWAP = 4890000000000000000 wei.

Non-sale: block 25954929 moved #76 0x368f->0x64af with approval+transfer only (no payment) - excluded, not a fill. WASH FLAG: tokenId 76 flipped twice in ~15h among fresh addresses (2.4 WETH then 4.89 ETH); flagged as suspected wash pattern but not excluded per rules (distinct counterparties, real payment, no proof of common ownership). TWAP math: no seed and 0 in-window fills; stale carry-forward gives P(t)=4.89e18 for all t, integral = 4890000000000000000*86400, /86400 = 4890000000000000000. FLOOR (context only, not in answer): OpenSea stats/events/listings endpoints returned 401 (no API key) at ~2026-09-22T20:05Z - stated limitation; CoinGecko floor_price 6.85 ETH (~$18896), volume_24h 0.0, one_day_sales null, corroborating zero sales.
