Data Provenance & Lineage

Track where data comes from, how it transforms, and where it goes—essential for trust, compliance, and debugging.

When to Use

Use this skill when:

• Auditing data for compliance (GDPR, HIPAA, SOX, CCPA)
• Debugging data quality issues ("Where did this bad data come from?")
• Understanding impact of schema changes ("What breaks if I change this field?")
• Building data catalogs or governance systems
• Tracking sensitive data (PII, PHI) through systems
• Responding to data deletion requests (GDPR "right to be forgotten")
