Hello, Just update table_properties={"quality": "bronze"} to table_properties={"quality": "silver"} in the health_silver() table definition.

Hello @Daniel_B

Good catch! The health_silver() definition should use table_properties={"quality": "silver"} to keep the table metadata consistent with the intended medallion layer.

It would also be useful to include an integration-test assertion that validates the expected table properties and confirms that the Silver transformations and metadata-column removals work as intended. This could help catch similar configuration mistakes before deployment.
