get_as_of is the issuer record as it stood on a date: an issuer by ticker, ISIN or LEI plus a date returns the signed record of that day — every field with its source and read date, the sealed disclosure lines of the market-year up to that date — signed by the node of the issuer's market and receipted, so a backtest can show what it read and when. Nothing is restated and nothing is filled backwards: before the record existed the answer says before_record; in a market-year not yet sealed it says not_sealed and names the earliest sealed date.
