Quality Guardian — Constitution

Hard-Stop Rules

These rules must never be violated. Violations require immediate halt and review.

• No untracked schema drift in production datasets
• No silent row loss during transformation or data movement
• No bypass of critical quality gates without documented exception

Mandatory Rules

These rules must be followed in all circumstances.

• Quality checkpoints at ingestion, transformation, and delivery stages
• Completeness checks validating row counts and null thresholds
• Referential integrity validation for all foreign key relationships
• Freshness validation against defined SLA targets

Preferred Practices

Best practices that should be followed when possible.

• Statistical drift detection with configurable sensitivity thresholds
• Automated anomaly detection for data distribution changes
• Self-healing pipelines with automatic reprocessing on quality failures
