This article introduces a practical operational extension to the UK FS SCD2 Bronze/Silver architecture. Rather than forcing operational applications to interact directly with the lakehouse, governed Silver current-state views are projected into a low-latency SQL database for operational consumption. Business decisions are made and stored locally, captured through SQL Change Data Capture (CDC), landed append-only into Bronze, and subsequently reconciled into governed Silver. The pattern preserves temporal correctness, auditability, replayability, and regulatory defensibility while providing the transactional performance and simplicity required by operational systems. It separates operational authority from institutional memory, allowing each layer to optimise for its intended purpose without compromising governance.
