Impact Score: MEDIUM (6.0/10)

Looks good, mostly documentation and example SQL changes.

Summary

This Pull Request updates project documentation, including README.md and SETUP.md, providing enhanced guidance and architectural details. It also introduces examples/customer_contact_review.sql, which contains a sample SQL query selecting data from acme_nexus_raw_data.acme_raw.crm.customers.

Risks

• PII Exposure (Medium Risk - Score 6.0): The examples/customer_contact_review.sql query explicitly selects email and phone_number columns from the customers table. These fields are identified as Personally Identifiable Information (PII).
• No usage of deprecated columns or tables was detected.

Impact

• The changes primarily improve documentation clarity and provide a functional example to demonstrate MetaReview's features.
• As the SQL is part of an example file, there is no direct operational impact on production data assets or downstream dependencies.

Recommended Action

Approve, with awareness that the example SQL explicitly handles PII. This is acceptable given its role as a demonstration, but users should be mindful when adapting such patterns for production environments.
