**TLDR:** A detailed lineage level that traces which source columns each field was derived from and how it was transformed.

<p>Column-level lineage goes beyond table-level visibility and shows the true origin of specific data fields. This level of detail is especially important for KPIs, model features, and regulated data elements. Knowing which source columns a dashboard metric was derived from greatly improves trust and auditability. Field-level traceability is one of the marks of maturity in modern data governance.</p>
