**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.
