# Catalog & Lineage
## Discover first
Automated PII/sensitive **discovery + column-level tagging** — you can't classify, protect, or action a DSR on data you haven't found.
## Lineage end-to-end
Source -> transforms -> consumers, automated from pipeline/dbt metadata. Enables impact analysis + DSR execution + trust.
## Glossary
Business terms ('customer', 'active') mapped to actual tables/columns — usable by humans.
## Maintained
Automate refresh; a stale catalog rots into confidently-wrong fiction. Feeds governance + privacy; enforcement -> data-platform/security-engineering.
