Hi @LingaReddy,

Thanks for taking the time to share such a comprehensive and well-structured breakdown — really appreciate the depth and clarity you’ve brought to this topic. The layer-wise retention model, clear separation between REORG vs. VACUUM, and the emphasis on auditability and automation via Unity Catalog and Workflows resonate strongly.

Fully aligned with the overall framework, especially the use of metadata-driven policies, centralized audit logs, and scalable purge orchestration. The tokenization/key-based erasure pattern for Silver SCD2 tables is a particularly valuable callout from an operational and compliance standpoint.

Thanks again for the valuable insights — this is extremely helpful and aligns well with the direction we’re driving.
