## Route Conflict Analysis

### ✅ **NO CONFLICTS DETECTED**

#### Conflict Prevention Strategies:
1. **Unique Base Paths:** Each feature has distinct base path
2. **Specific Routes First:** More specific routes registered before generic ones
3. **ID Validation:** Routes with `:id` validated to prevent overlap
4. **HTTP Method Separation:** Same paths use different HTTP methods

#### Potential Conflict Points (Resolved):
1. ✅ `/api/users/:id` vs `/api/users/me` - NOT present (no conflict)
2. ✅ `/api/sessions/:sessionId` vs `/api/sessions/all` - Different methods
3. ✅ `/api/rbac/roles/:roleKey` vs `/api/rbac/roles` - Specific order OK
4. ✅ `/api/vpn/configs/:id` vs `/api/vpn/configs/upload` - POST vs GET
