Key question

How do you know the platform is producing data that is safe to use?

The first case will use AWS Glue Data Quality and schema validation to detect invalid inputs before they propagate. It will include Terraform, measurable rules, failure evidence, cost notes, and complete cleanup.

Planned evidence

• Valid and invalid input samples
• Data quality rule outcomes
• Schema failure handling
• Operational signals
• Exam guidance compared with production guidance
