Entire dedicated collection, all live token IDs and all sets/revealed states; no shared-contract project or trait filter. Other chains and other contracts excluded.",
    "slug": "opepen-edition, resolved from CoinGecko official marketplace link and verified against OpenSea collection metadata contracts[0] on ethereum; not inferred from CoinGecko id.",
    "floorRule": "Prefer fresh OpenSea total.floor_price with ETH/WETH symbol and matching collection. Otherwise use fresh CoinGecko floor_price.native_currency with ethereum/ETH native currency. Do not average. Relative discrepancy is (CoinGecko/OpenSea - 1)*100%.",
    "time": "Fresh HTTP retrievals during assessment; source HTTP Date is response time, not price last_updated. Reject determinably older-than-one-hour prices. APIs supplied no price last_updated; underlying age cannot be independently established. Pinned blocks apply only to sales corroboration, not historical listing reconstruction.",
    "sales": "Latest three sales shown by OpenSea collection activity whose receipt blocks fall inclusively in 26021228..26028374. Order by descending block, transaction and log position. Successful receipts plus decoded Seaport OrderFulfilled establish sale; Transfer alone does not. Exclude mints, gifts, self-transfers and unattributable bundles.",

    "freshnessFallback": "Attempt both providers and official collection-page fallback on access failure. Use only available credentials. Report access failures and unavailable timestamps; do not use search snippets or missing-data sentinels.",
    "ranking": "Batch membership is fixed by the pinned Ethereum-only rank 36/global rank 52 snapshot at 2026-09-21T20:48:44.848Z; later ranking changes do not change the collection.",
    "reproduction": "Panel evidence: GET recipe.source, verify ETH symbol and collection, parse total.floor_price exactly, multiply by 10^18. This reproduces the arithmetic for the recorded response, not a future live quote. Offchain listings cannot be reproduced from public RPC alone; no onchain floor surrogate is used."
