Coordinator Role Guard
Component Detail
Description
Utility that enforces coordinator or higher role authorization before granting access to proxy registration UI and service endpoints. Redirects unauthorized users to the no-access screen.

Summaries
The Coordinator Role Guard protects sensitive proxy registration workflows by ensuring only authorized coordinators and above can access critical administrative functions. This security control directly reduces the risk of unauthorized data entry, compliance violations, and fraudulent activity registrations. By systematically blocking peer mentors from accessing coordinator-level screens, the organization maintains a clear chain of accountability and audit trail. This translates into reduced operational risk, stronger governance posture, and protection of organizational reputation — all without additional manual oversight or staffing cost.
This is a low-complexity shared component with zero declared dependencies, making it one of the safest items on the delivery backlog. It guards multiple routes simultaneously and is reusable across any future coordinator-restricted feature, reducing the need to rebuild access control logic per screen. Testing requires mock user sessions with varying roles and confirmation that redirect behavior is correct. Since it is shared, any regression here could affect multiple features — it should be integration-tested against each guarded route as part of the QA pass.
Estimated delivery is low-risk with minimal rework probability.
Implements Flutter route guard pattern using a `guardRoute(BuildContext, WidgetBuilder)` wrapper that evaluates the current session's UserRole before rendering the protected widget tree. The `canAccess(UserRole)` method checks the role against a coordinator minimum threshold and the `assertCoordinatorOrAbove(String userId)` method provides an imperative check for service-layer validation. Unauthorized access triggers `redirectToNoAccess(BuildContext)` and logs the attempt for audit. References the `user-role` data model.
Because this is a shared component, any changes to the UserRole enum or session token structure will require this component to be updated and tested across all consuming routes.
Responsibilities
- Check current session user's role against coordinator minimum threshold
- Block navigation to proxy screens for peer mentor role users
- Provide a Flutter route guard wrapper for declarative access control
