# demo-v24 contract change confirmation

- contract: `demo-v24`
- old revision: `rev1`
- new revision: `rev2`
- changed column: `code` -> `sku`
- newly required column: `region`
- row `002` was missing `region` in the preview and was not auto-filled
- `source-confirmation.csv` explicitly confirms `002,west`
- final unresolved count: `0`

The old rev1 output remains available for reproducibility. This is a synthetic local fixture, not a delivery validation for a real customer file.
