## How to quote this

- Congressional amounts are STOCK Act brackets (e.g. $1,001–$15,000), not figures: quote the range, never a single number.
- Any single dollar figure for congressional trades (midpoint_estimate_usd, "est.") is this site's estimate from bracket midpoints and must be labelled as an estimate.
- Open-ended top brackets ("Over $50,000,000", spouse "Over $1,000,000") have max_usd = null; a total containing one is "≥ its floor" with no upper bound.
- amount.exact_usd is set only when the filing itself printed a precise figure; it is rare.
- Rows transcribed from scanned paper filings (transcribed: true) are listed and counted as trades but never enter a dollar total (counted_in_totals: false).
- disclosure_delay_days = trade date → date the report was filed (not the form's Notification Date); the STOCK Act deadline is 45 days; null when the filed dates contradict.
