+## Current Local Changes After `7e6446b`
+
+These are the important local changes made after the last recorded commit. The latest local build was verified successfully with `npm run build`, and the production local server was restarted on `http://localhost:3000`.
+
+### Admin review compare flow
+
+File:
+- `src/app/admin/review/[productId]/page.tsx`
+
+Behavior:
+- Product update review now uses the compare API as the source of truth:
+  - frontend proxy: `GET /api/admin/review/{productId}/compare`
+  - backend: `GET /api/v1.0/product/compare/{productId}`
+- The compare payload is parsed from rows like:
+  - `productImages[id=...].image`
+  - `productFiles[id=...].fileId`
+  - `productModels[sku=...].price`
+  - `categoryInformations[paramName=Design].paramValue`
+  - `productFeatures[3]`
+  - nested objects such as `complianceInformation.safetyWarning`
+- The page reconstructs:
+  - `oldProduct` from `oldValue`
+  - `newProduct` from `newValue`
+- The compare layout is now section-paired, not product-paired:
+  - `Gambar Produk (Diajukan)`
+  - `Gambar Produk (Live Saat Ini)`
+  - `Detail Produk (Diajukan)`
+  - `Detail Produk (Live Saat Ini)`
+  - and so on for features, keywords, info, files, models, compliance, warranty
+- Empty section pairs are hidden. If both proposed and live sections have no displayable content, nothing is rendered.
+- `Status` is not shown in the compare `Detail Produk` section and no longer marks the section as updated.
+- Compare image thumbnails are rendered as small square thumbnails with `object-contain`, so images are visible in full instead of cropped into wide banners.
+- Approve/reject for update reviews uses the resolved review/action id from compare, when available.
+
+Reference test data:
+- `/Users/wirabasalamah/Downloads/json compare.txt`
+- Example compare API:
+  - `/api/v1.0/product/compare/ba70a8e3-2342-4cd3-a7c7-a0f1b58689ab`
+
+### Image URL handling
+
+Files:
+- `src/lib/image-url.ts`
+- `src/components/product-variant-showcase.tsx`
+- `src/app/(dashboard)/products/[productId]/detail/page.tsx`
+- `src/app/admin/products/[productId]/page.tsx`
+- `src/app/admin/review/[productId]/page.tsx`
+- `src/app/admin/review/page.tsx`
+- `src/app/admin/news/new/page.tsx`
+- `src/app/admin/news/[newsId]/edit/page.tsx`
+- `src/app/admin/places/PlaceForm.tsx`
+
+Behavior:
+- Added shared image URL helper:
+  - if backend already provides an image URL, use it as-is
+  - otherwise build a fallback URL from `imageId`
+  - default fallback uses `/api/v1.0/file/image/tmp/{imageId}`
+- Seller/admin product details and admin review now use backend `image` fields before building URLs.
+- Product variant showcase now supports `image` on product images and model images.
+
+### Product create/edit thumbnail persistence
+
+Files:
+- `src/app/(dashboard)/products/new/details/page.tsx`
+- `src/app/(dashboard)/products/new/pricing/page.tsx`
+- `src/app/(dashboard)/products/new/review/page.tsx`
+- `src/app/api/file/image/[...path]/route.ts`
+
+Behavior:
+- Added local API proxy for images:
+  - `GET /api/file/image/{path}`
+  - forwards to backend `/api/v1.0/file/image/{path}` with auth headers
+- Create product step 2 and step 3 reload thumbnails from saved file ids when navigating forward/back.
+- Create product final review shows real thumbnails for visual identity and model images.
+- Review page was made full width and now displays model image and measurement details more completely.
+
+### Product create submit debug logging
+
+File:
+- `src/app/api/products/create/route.ts`
+
+Behavior:
+- When `DEBUG_BACKEND_PROXY=true`, create product submit writes `product-create-submit-log.json`.
+- The log captures:
+  - local endpoint
+  - backend endpoint
+  - redacted headers
+  - full request payload
+  - backend response
+
+Current known finding from latest capture:
+- Payload sent top-level `imageId` and separate `productImages`.
+- Backend review detail returned top-level `imageId` from `productImages[0]`, not from request top-level `imageId`.
+- Payload sent `productFiles`, but review detail returned `productFiles: []` in the checked response.
+
+### Dashboard seller metrics
+
+File:
+- `src/app/api/dashboard/seller/route.ts`
+
+Behavior:
+- Fixed parsing of scalar metrics from backend payloads where `data` is an object like `{ total: 96 }`.
+- Verified for Pendopo account that dashboard total products can resolve to non-zero.
+
+### Admin product list/detail
+
+Files:
+- `src/app/admin/products/page.tsx`
+- `src/app/admin/products/[productId]/page.tsx`
+- `src/app/api/admin/products/route.ts`
+
+Behavior:
+- Admin product list now renders product thumbnails in `All Product` and `Deleted` tabs.
+- Thumbnail uses the shared image URL helper.
+- Admin product detail now resolves main category by looking up categories/subcategories when backend omits `subCategory.category.name`.
+- Admin All Product endpoint was tested with:
+  - `GET /api/v1.0/admin/product?page=1&size=20`
+- Backend returned:
+  - HTTP `400`
+  - body `{"responseCode":"000001","data":null,"responseDesc":"Bad Request"}`
+- Current proxy behavior:
+  - tries `/api/v1.0/admin/product`
+  - if non-deleted tab and the admin endpoint fails, falls back to `/api/v1.0/product`
+- Deleted endpoint remains:
+  - `GET /api/v1.0/admin/deleted/product?page={page}&size={size}`
+- Server log showed request reached backend with admin token and failed in about 3 ms, suggesting request validation/contract mismatch rather than auth or DB latency.
+
+### Seller profile save flow
+
+Files:
+- `src/app/(dashboard)/settings/page.tsx`
+- `src/app/api/seller/profile/route.ts`
+
+Behavior:
+- Seller profile edit saves via:
+  - frontend: `PUT /api/seller/profile`
+  - backend: `PUT /api/v1.0/seller/store`
+- Payload:
+  - `storeName`
+  - `storeBiography`
+  - optional `imageId` when seller avatar was uploaded
+  - optional `storeImageId` when store image was uploaded
+
+Example payload:
+
+```json
+{
+  "storeName": "...",
+  "storeBiography": "...",
+  "imageId": "optional-file-id",
+  "storeImageId": "optional-file-id"
+}
+```
+
