## From README

Optimize Storage Costs (Dead-end and Unused Tables) Purpose Identify and remove BigQuery tables that contribute to storage costs but have no active consumption, based on Masthead Data lineage analysis. Prerequisites Verify the Masthead Data integration is version v0.2.7+ (required for accurate lineage data). Table Categories Masthead Data uses lineage analysis to identify tables, but relies on visible pipeline references. Modification timestamps are critical: | Type | Definition | Indicators | Watch for | | --- | --- | --- | --- | | Leaf dead-end | Leaf table in a dead-end chain — regularly updated, no downstream consumers. Directly actionable.
