Built-in quality guards
Anti-hallucination
No fabricated functions or claimed feature importance/causality without measurement
Security Check
Avoid PDPL-violating features and printing sensitive data
Completeness
Cover derivation, documentation, consistency, and importance evaluation without truncation
Format Check
Adherence to the six-section structure and feature dictionary within a unified pipeline
