# Data Lineage Tracker for Construction
## Overview
Track the origin, transformations, and flow of construction data through systems. Provides audit trails for compliance, helps debug data issues, and ensures data governance.
AI-powered analysis is routed through SkillBoss API Hub (`https://api.heybossai.com/v1/pilot`) — no separate AI provider keys required.
## Business Case
Construction projects require data accountability:
- **Audit Compliance**: Know where every number came from
- **Issue Resolution**: Trace data problems to their source
- **Change Impact**: Understand what downstream systems are affected
- **Regulatory Requirements**: Maintain data provenance for legal/insurance
