  "notes": "Method: verified contract onchain (name/symbol/totalSupply match CoinGecko id). OpenSea Events API (api.opensea.io/api/v2/events/collection/...) returned 401 Missing API Key in this environment (no credentials available) so OpenSea could not be used for discovery; fell back to direct onchain discovery via eth_getLogs for Transfer(address,address,uint256) on the contract, using public RPCs https://mainnet.gateway.tenderly.co and https://rpc.mevblocker.io (chainId and toBlockHash 0xbd3933... confirmed matching the pin on both). Scanned seed lookback + window, blocks 25977724-26035049 (7d before start through toBlock): 0 Transfer events -> 0 candidate sales, so no in-window qualifying fill and no seed within 7 days per the seed definition. Extended an exploratory scan back to block 23977723 (~35 days) to sanity-check liquidity: found only 6 Transfer events total across ~35 days; spot-checked the one nearest the window (block 25902268, tx 0xb2a487f9...dcedf) and it is a bare ERC721 safeTransferFrom (selector 0xb88d4fde, tx value=0 ETH, no WETH transfer, no Seaport OrderFulfilled or other marketplace settlement log in the receipt) -- i.e. a non-sale transfer, not a qualifying paid sale. So even relaxing the 7-day rule, no verifiable priced secondary sale was found near the window. CoinGecko (contract-verified) independently corroborates: volume_24h.native_currency=0 and market has only ~40 unique addresses across 42 tokens, consistent with an effectively untraded high-value 1/1 collection (floor 499 ETH / ~$1.37M). Conclusion: per the brief's own 'seed' and 'missing' definitions, the 24h last-sale TWAP is unavailable for this window -- there is no seed fill within 7 days and no in-window fill. answer/figure are set to '1' (the guards.min value) purely as a schema-compliant non-zero placeholder for 'unavailable', explicitly not a fabricated price; zero was avoided since the brief states zero is not a valid missing-data sentinel. OpenSea listing floor could not be independently confirmed here for lack of API credentials; CoinGecko's floor_price.native_currency=499 ETH is reported as context only per the 'floor' definition and was not used in the TWAP."
