## Recent Commits

- `e9a0cd0` `Update product review, measurement, and backend logging flows`
- `b266047` `Fix TypeScript build errors in product detail and admin review`

## Main Changes

### 1. Backend proxy logging

Files:
- `src/lib/backend-fetch-logger.ts`
- `src/instrumentation.ts`
- `.env.local` uses `DEBUG_BACKEND_PROXY=true` locally

Behavior:
- Logs server-side `fetch` requests to backend
- Logs request method, URL, headers, body preview
- Logs response status, duration, headers, body preview
- Redacts authorization header

Use this when tracing frontend-to-backend failures in local dev.

## 2. Product measurement mode on add product

Files:
- `src/app/(dashboard)/products/new/pricing/page.tsx`
- `src/lib/use-product-submit.ts`
- `src/app/(dashboard)/products/new/review/page.tsx`

Behavior:
- Each model has a `Product Measurement` switch
- When enabled:
  - nested measurements are shown
  - model-level price, currency, weight, dimensions, promotion, packaging, and warehouse stock are disabled
  - at least 1 measurement row is required
- Submit payload uses `model.hasMeasurements`
- When measurement mode is active, model-level numeric fields are zeroed and model warehouses are omitted

## 3. Product measurement mode on edit product

File:
- `src/app/(dashboard)/products/[productId]/edit/page.tsx`

Behavior:
- Matches add-product measurement behavior
- Uses explicit `hasMeasurements` state instead of guessing from array length
- Disables model-level fields when measurement mode is on

## 4. Seller product review page improvements

File:
- `src/app/(dashboard)/products/new/review/page.tsx`

Behavior:
- Review now renders actual product thumbnails using backend file URLs
- Previously it only showed image indicators, which was confusing
- Review also reflects measurement-based pricing correctly

## 5. Product list page improvements

File:
- `src/app/(dashboard)/products/page.tsx`

Behavior:
- Edit stock/price modal supports:
  - choosing model
  - choosing measurement if present
  - choosing warehouse
- Warehouse labels use warehouse names from master warehouse API, not raw UUIDs
- Product row status badges now show explicit state like active, draft, review, unpublished, deleted, rejected

## 6. Product detail page improvements

File:
- `src/app/(dashboard)/products/[productId]/detail/page.tsx`

Behavior:
- Main category now resolves even when backend omits `subCategory.category.name`
- Warehouse display now uses warehouse master names instead of UUID slices
- TypeScript nullability issue for category resolution was fixed here

## 7. Admin review page improvements

File:
- `src/app/admin/review/[productId]/page.tsx`

Behavior:
- Review supports model + measurement structures
- New product review and compare review now handle measurement-driven price/weight/dimension/promo/stock
- Compare view highlights updated sections using backend compare response and `isUpdate`
- Product images are rendered using main image + gallery images
- TypeScript issue around `row.field` nullability was fixed here

## 8. Sidebar submenu reliability

Files:
- `src/components/product-submenu-nav.tsx`
- `src/components/admin-product-submenu-nav.tsx`

Behavior:
- Click behavior was hardened because submenu items were sometimes not navigating
- Navigation is explicit via `router.push(...)`

## Translation Files Touched

- `src/lib/translations/id.ts`
- `src/lib/translations/en.ts`

These include labels added for statuses and stock/price modal UI.

## Important Findings

### Admin review image issue

For at least one reviewed product, backend review payload returned:

- `image: null`
- `imageId: null`
- `productImages: []`

In that case frontend cannot render images. If an image is missing in review, verify backend review payload before debugging frontend.

### Edit product empty main image behavior

In edit product submit flow, empty `imageId` is currently sent as `undefined`, which means the field is omitted from JSON payload, not sent as `null` and not sent as empty string.

If backend requires explicit image removal via `null`, this behavior will need to be changed.

## Local Dev Notes

Run local dev:

```bash
npm run dev
```

Build verification:

```bash
npm run build
```

## Dev Server Update Guide

Based on current deployment notes, dev server update flow is:

```bash
sudo -iu inadev
cd ~/apps/ina-trading-web
git pull origin main
npm ci
npm run build
pm2 restart ina-trading-dev
pm2 save
sudo -iu inadev pm2 status
```

Optional logs:

```bash
sudo -iu inadev pm2 logs ina-trading-dev --lines 100
```

## Suggested Next Checks

- Verify whether backend expects `null` when main image is intentionally removed during edit
- Verify seller and admin review payload consistency for image fields
- Verify warehouse master API always contains all warehouse IDs referenced in product payloads
- If submenu click issue still appears, inspect layout overlays with browser tooling
- Consider adding field-level compare highlighting, not only section-level highlighting, in admin review compare page
