  "notes": "I read the Ethereum Foundation Blog post, which states: the price was initially 2000 ETH per BTC (for 14 days) before declining. I used that stated initial rate as the whole-number answer. The pinned closing block 26049164 had the requested hash on public Ethereum RPC endpoints https://rpc.flashbots.net/fast and https://rpc.mevblocker.io/fast; per the brief, that window timestamps this off-chain historical fact."
