The catalog team and customer operations team need reports with different access boundaries. A secure view limits the exposed columns and protects its definition. A masking policy changes returned values, while a row access policy limits which records a role sees. Test the requested reader role because an owner can see a different branch of the same policy.
The scan exercises revisit clustering metadata and bounded predicates. Their local profiles describe a simulated partition model, so they provide practice reading pruning evidence rather than measured Snowflake performance. Keep the requested output correct first. Each setup is independent, and no exercise asks you to disable a policy simply to make a query return more rows.
