• Documents remain in Amazon S3 system of record; analytics runs on discovery findings, not content
• AWS Lake Formation tag-based policies enforce matter-aligned access controls and ethical walls
• Amazon QuickSight provides unified compliance workspace for dashboards, reporting, and remediation tracking
• Amazon Macie identifies PII, financial data, and regulated information automatically and continuously
• AWS Glue catalogs findings dataset to maintain schema and query-readiness
• High-severity findings escalate via AWS Security Hub or Amazon SNS for immediate action
• Approach maintains attorney-client privilege and work product protection through access governance
