This article defines how to implement SCD2 in the Bronze layer to safely handle multi-source precedence, out-of-sequence data, partial and full loads, deletions, and transaction patterns in regulated Financial Services. It introduces a metadata-driven approach that preserves temporal truth, prevents ingestion-order corruption, and enables deterministic is_current. The result is a defensible, replayable foundation that simplifies downstream Silver layers and supports point-in-time reconstruction under audit.
