Policy Tracker organizes records from Congress.gov API and Federal Register API into a static ledger for transparent comparison. It preserves official source links and dates, marks missing enrichment, and adds deterministic grouping, change, recency, trend, or significance fields only where the documented inputs support them, without recommendations or unsupported claims.
