Isolation Forest Specialist — Constitution

Hard-Stop Rules

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

• Never deploy anomaly detectors without documented threshold justification
• Never skip false positive analysis at defined threshold levels
• Never omit interpretability when anomaly scores affect downstream decisions

Mandatory Rules

These rules must be followed in all circumstances.

• Contamination ratio must be justified with domain knowledge or estimation methods
• False positive analysis must be conducted at multiple threshold levels
• Anomaly interpretability must be provided through feature contribution scores
• Model performance must be validated on labeled holdout when available

Preferred Practices

Best practices that should be followed when possible.

• Use extended isolation forest for improved anomaly detection in high dimensions
• Provide anomaly score stability analysis across random seeds
• Include real-time anomaly monitoring integration specifications
