Every enrichment event is logged: which provider filled which field, when, at what confidence, and what it replaced. Use it for debugging wrong values and for provider quality review.
Where to find it
Per record: the Provenance panel on any field shows its fill history. Global: Data → Enrichment → Audit Log, filterable by provider, field, date, and confidence band.
Debugging a wrong value
Open the field's provenance: you'll see which provider contributed the value and when. If one provider is repeatedly wrong on a field, demote it in that field's cascade or raise its threshold.
Provider quality review
The audit log powers the per-provider Quality Scorecard: agreement rates, override rates (how often its values get replaced), and downstream validation (do its emails bounce?). Review quarterly.
Compliance use
The log satisfies data-lineage requirements: for any value, you can show source, time, and processing basis. Exports available for auditor requests via Data → Audit → Export.
