//! Popperian Falsification Checklist Implementation
//!
//! Implements the 108-item Sovereign AI Assurance Protocol checklist.
//! Each checklist item is a falsifiable claim with explicit rejection criteria.
//!
//! # Toyota Way Integration
//!
//! - **Jidoka**: Automated gates stop pipeline on failure
//! - **Genchi Genbutsu**: Evidence-based verification
//! - **Kaizen**: Continuous improvement via metrics
//!
//! # Severity Levels
//!
//! - **Critical**: Project FAIL - blocks release
//! - **Major**: Requires remediation before release
//! - **Minor**: Documented limitation
//! - **Info**: Clarification needed
//!
//! # Implemented Sections (108 Items Total)
//!
//! - Section 1: Sovereign Data Governance (SDG-01 to SDG-15) - 15 items
//! - Section 2: ML Technical Debt Prevention (MTD-01 to MTD-10) - 10 items
//! - Section 3: Hypothesis-Driven Development (HDD-01 to EDD-03) - 13 items
//! - Section 4: Numerical Reproducibility (NR-01 to NR-15) - 15 items
//! - Section 5: Performance & Waste Elimination (PW-01 to PW-15) - 15 items
//! - Section 6: Safety & Formal Verification (SF-01 to SF-10) - 9 items
//! - Section 7: Jidoka Automated Gates (JA-01 to JA-12) - 9 items
//! - Section 8: Model Cards & Auditability (MA-01 to MA-10) - 10 items
//! - Section 9: Cross-Platform & API (CP-01 to CP-05) - 5 items
