  "notes": "The requested historical cross-marketplace floor cannot be reproduced from public Ethereum RPC data alone because unfilled signed marketplace orders can remain off chain. The request selects evidence=panel, whose catalogue recipe does not execute a chain computation. This conflicts with the RPC-only acceptance criterion. This artifact therefore does not satisfy RPC-only reproduction or establish the floor over the exact pinned window. It records the closest available observed floor, without changing the pinned fields or claiming historical validity. OpenSea stats returned total.floor_price=0.0927999 and floor_price_symbol=ETH. Exact multiplication by 10^18 yields the answer. https://api.opensea.io/api/v2/listings/collection/opepen-edition/best?limit=1 also returned current.value=92799900000000000 for token 5063: consideration 91871901000000000 + 927999000000000 wei. That order was created at timestamp 1789943230, after closing timestamp 1789940219; it cannot establish a closing-block listing. https://api.coingecko.com/api/v3/nfts/opepen-edition returned 0.0928 ETH. Blur api.blur.io failed DNS and core-api.prod.blur.io returned HTTP 403 for /v1/collections/0x6339e5e072086621540d0362c4e3cea0d643e114. eth_chainId and eth_getBlockByNumber(0x18d0e62,false) on https://rpc.flashbots.net/fast and https://one.valve.city/rpc/vk_demo/evm/1 both confirmed chain 1 and the exact pinned closing hash, with timestamp 0x6ab052bb. https://ethereum-rpc.publicnode.com, https://rpc.mevblocker.io/fast and https://eth.drpc.org returned HTTP 403. The successful marketplace reads used User-Agent Mozilla/5.0; a later OpenSea stats read without that header returned 403. Reproduce the observed arithmetic by parsing the quoted floor decimal exactly and multiplying by 10^18. The live panel source may change, is not pinned to the block range, and cannot provide immutable RPC-only reproduction. No alternative block window or unrelated chain statistic was substituted."
