Notes and record state

Record note
Current first-party documentation identifies Ostium as an onchain perpetual instruments platform on Arbitrum with self-custodied collateral, onchain position settlement, real-world and crypto markets, request-for-quote execution, and direct smart-contract access. Current independently maintained metrics report substantial non-zero perpetual volume, fees, revenue, TVL, and open interest. No exact launch date, legal jurisdiction, predecessor, successor, or terminal lifecycle fact is asserted.
