Role Permissions

Current Implementation

• All users are anonymous Readers
• No authentication system
• No reputation tracking
• No role-based permissions

Target Design

Simplified flat role structure:

• Three roles only: Reader (default), Contributor (earned), Moderator (appointed)
• Reputation system replaces role hierarchy
• Progressive permissions based on reputation, not titles
