User Class Diagram

User Class Diagram

This diagram shows the complete user role hierarchy in FactHarbor with two independent tracks from Contributor: the Content Track (→ Reviewer → Auditor/Expert/Moderator) and the Technical Track (→ Maintainer).

Key points:

• Moderator derives from Reviewer (not from Expert)
• Maintainer derives from Contributor (not from Reviewer)
• Technical Users (system processes) extend Reader, not Contributor
