Anti-Fragile take
Data lineage answers: where did this email come from? Which provider? When? Was it validated? Without lineage, you cannot debug bad data or trust enrichment.
We track lineage for every enriched field: source provider, timestamp, validation status, and transformation history.
Why it matters
When a rep gets a bounced email from "verified" data, lineage tells you which step failed.
How we build it
Lineage columns on every enriched field, provider audit trail, and debugging dashboards for data quality issues.
