Operationalizing Fannie Mae Selling Guide A3-4-02 — Data Quality and Integrity

This is verbatim, source-snapshotted regulator text from the Claude for Compliance open corpus. To turn a rule like this into compliance work product: gap-analyze your policies and procedures (P&Ps) against these requirements to surface stale, conflicting, or missing provisions; operationalize any change with a ready-to-run update kit; and produce audit-ready evidence — every step grounded only in the regulator’s own words, never invented.
