+The 2,457 scanned paper filings (document IDs starting with 8 or 9, mostly 2014–2019) are not in the trade table yet. They're listed in `house_ptr_unparsed_filings.parquet`, and their OCR text will be added in a later update.

+## congress_trades.parquet (66,865 rows)
+Senate and House trades combined, ready for backtests. Columns are the same as above (`member_name` replaces `senator_name`), and the `chamber` column tells the two apart.

 Amounts are ranges by law. Data is as disclosed; late or amended filings may be missing. For research only.
