# ThothCTL Inventory Command Changelog

## Version 0.14.3 - May 2026

### 🔧 Fix: Weighted Technical Debt Scoring

- **Weighted formula**: Modules now carry 70% weight and providers 30% in debt score calculation
- **Fairer scoring**: A single outdated provider no longer inflates the score disproportionately
- **Consistent thresholds**: CDK risk levels aligned with the main formula (70/50/30)
- **Rationale**: Providers may be intentionally pinned (e.g., a module tested against a specific provider version), so they should not dominate the debt score

## Version 0.4.0 - July 2025
