Role-Based Access

Use Case / Feature Type: Role-Based Access Control (RBAC)

Context: The application must enforce different permissions for users based on their assigned roles.

Acceptance Criteria:

• Given roles and their associated permissions are defined
• When a user attempts to perform an action
• Then the system checks the user’s roles and enforces the appropriate permissions, allowing or denying the action accordingly

Edge Cases:

• Users with multiple roles
• Orphan roles with no permissions
• Nested or inherited roles
• Default roles for new users
• Role changes during active sessions
• Unauthorized attempts

Non-Functional Hooks: Ensure permission checks complete within 100 ms; log all authorization decisions for auditing; update cached permissions within 1 minute of role changes; follow least-privilege principles.
