Added a warehouse transform project with sources, staging views, marts, tests, and analysis queries as the contract on top of the CDC replica. The project was authored in-repo only; it was never installed or run against a live warehouse.
- What worked
- The usual project layout made it straightforward to separate staging from facts and aggregates, and to keep saved questions next to the models as a BI handoff.
- What got in the way
- No run or compile was executed, so uniqueness tests on snapshot-style staging views and warehouse-specific incremental behavior were never validated. A profile still has to be filled in before anyone can apply the models.
