+# Session Log: Admin Console Fixes
+Date: 2025-12-11
+
+## Overview
+This session focused on debugging and resolving critical display and functionality issues in the Admin Console. Major fixes included Data integration for Document Numbering, RBAC Matrix functionality, and resolving data unwrapping issues for Active Sessions and Logs.
+
+## Resolved Issues
+
+### 1. Tag Management
+- **Issue:** 404 Error when accessing system tags.
+- **Cause:** Incorrect API endpoint (`/tags` vs `/master/tags`).
+- **Resolution:** Updated frontend service to use the correct `/master` prefix.
+
+### 2. Document Numbering
+- **Issue:** Project Selection dropdown used hardcoded mock data.
+- **Cause:** `PROJECTS` constant in component.
+- **Resolution:** Implemented `useProjects` hook to fetch dynamic project list from backend.
+
+### 3. RBAC Matrix
+- **Issue:** Permission checkboxes were all empty.
+- **Cause:** `UserService.findAllRoles` did not load the `permissions` relation.
+- **Resolution:**
+    - Updated `UserService` to eager load relations.
+    - Implemented `updateRolePermissions` in backend.
+    - Added `PATCH` endpoint for saving changes.
+
+### 4. Active Sessions
+- **Issue:** List "No results" and missing user names.
+- **Cause:**
+    - Property mismatch (`first_name` vs `firstName`).
+    - Frontend failed to unwrap `response.data.data` (Interceptor behavior).
+- **Resolution:**
+    - Aligned backend/frontend naming convention.
+    - Updated `sessionService` to handle wrapped response data.
+    - Improved backend date comparison robustness.
+
+### 5. Numbering Logs
+- **Issue:** Logs table empty.
+- **Cause:** Same data unwrapping issue as Active Sessions.
+- **Resolution:** Updated `logService` in `system-logs/numbering/page.tsx`.
+
+### 6. Missing Permissions (Advisory)
+- **Issue:** 403 Forbidden on Logs page.
+- **Cause:** `system.view_logs` permission missing from user role.
+- **Resolution:** Advised user to use the newly fixed RBAC Matrix to assign the permission.
+
+## Verification
+All issues were verified by manual testing and confirming correct data display in the Admin Console. Backend logs were used to debug the Active Sessions data flow.

+# Session Summary: Frontend Integration Review & Fixes
+
+**Date:** 2025-12-11
+**Session ID:** ae7069dd-6475-48f9-8c85-21694e014975
+
+---
+
+## Objective
+
+Review frontend integration status and fix minor issues in Correspondences, RFAs, and Drawings modules.
+
+## Work Completed
+
+### 1. Integration Review ✅
+
+Verified that all 3 core modules are properly integrated with Backend APIs:
+
+| Module            | Service                       | Hook                    | API Endpoint         | Status     |
+| ----------------- | ----------------------------- | ----------------------- | -------------------- | ---------- |
+| Correspondences   | `correspondence.service.ts`   | `use-correspondence.ts` | `/correspondences`   | ✅ Real API |
+| RFAs              | `rfa.service.ts`              | `use-rfa.ts`            | `/rfas`              | ✅ Real API |
+| Contract Drawings | `contract-drawing.service.ts` | `use-drawing.ts`        | `/drawings/contract` | ✅ Real API |
+| Shop Drawings     | `shop-drawing.service.ts`     | `use-drawing.ts`        | `/drawings/shop`     | ✅ Real API |
+
+### 2. Minor Issues Fixed ✅
+
+#### 2.1 `components/drawings/list.tsx`
+- **Issue:** Hardcoded `projectId: 1`
+- **Fix:** Added optional `projectId` prop to `DrawingListProps` interface
+
+```diff
+interface DrawingListProps {
+  type: "CONTRACT" | "SHOP";
++  projectId?: number;
+}
+
+-export function DrawingList({ type }: DrawingListProps) {
+-  const { data: drawings, isLoading, isError } = useDrawings(type, { projectId: 1 });
++export function DrawingList({ type, projectId }: DrawingListProps) {
++  const { data: drawings, isLoading, isError } = useDrawings(type, { projectId: projectId ?? 1 });
+```
+
+#### 2.2 `hooks/use-drawing.ts`
+- **Issue:** `any` types in multiple places
+- **Fix:** Added proper types
+
+```diff
++type DrawingSearchParams = SearchContractDrawingDto | SearchShopDrawingDto;
++type CreateDrawingData = CreateContractDrawingDto | CreateShopDrawingDto;
+
+-export function useDrawings(type: DrawingType, params: any) {
++export function useDrawings(type: DrawingType, params: DrawingSearchParams) {
+
+-mutationFn: async (data: any) => {
++mutationFn: async (data: CreateDrawingData) => {
+
+-onError: (error: any) => {
++onError: (error: Error & { response?: { data?: { message?: string } } }) => {
+```
+
+#### 2.3 `hooks/use-correspondence.ts`
+- **Issue:** `any` types and missing mutations
+- **Fix:**
+  - Added `ApiError` type for error handling
+  - Imported `WorkflowActionDto` for proper typing
+  - Added `useUpdateCorrespondence()` mutation
+  - Added `useDeleteCorrespondence()` mutation
+  - Replaced all `any` types with proper types
+
+## Files Modified
+
+1. `frontend/components/drawings/list.tsx`
+2. `frontend/hooks/use-drawing.ts`
+3. `frontend/hooks/use-correspondence.ts`
+
+## Conclusion
+
+All frontend business modules (Correspondences, RFAs, Drawings) are confirmed to be properly integrated with Backend APIs using TanStack Query. The security features (Idempotency-Key, JWT injection) are correctly implemented in the API client. Minor type safety issues have been resolved.
