### 📋 Issue Analysis

**Issue #1847**: Supplier data sync delay causing false out-of-stock

```
Problem Description:
- Taiwan/Japan supplier data sync is delayed
- Website shows "Out of Stock" but items are actually available
- Affected Product: 101 Pineapple Cake

Root Cause:
- API connection timeout set too short (5 seconds)
- No retry mechanism
- Incomplete error handling
```

### 🛠️ Auto-Fix Details

#### Modified File: `src/services/supplier-sync.ts`

```diff
// supplier-sync.ts

- const API_TIMEOUT = 5000; // 5 seconds
+ const API_TIMEOUT = 30000; // 30 seconds

- async function fetchSupplierData(supplierId: string) {
-   const response = await fetch(supplierEndpoints[supplierId]);
-   return response.json();
- }
+ async function fetchSupplierData(supplierId: string, retries = 3) {
+   for (let attempt = 1; attempt <= retries; attempt++) {
+     try {
+       const controller = new AbortController();
+       const timeoutId = setTimeout(() => controller.abort(), API_TIMEOUT);
+
+       const response = await fetch(supplierEndpoints[supplierId], {
+         signal: controller.signal
+       });
+       clearTimeout(timeoutId);
+
+       if (!response.ok) {
+         throw new Error(`HTTP ${response.status}`);
+       }
+       return response.json();
+     } catch (error) {
+       console.error(`Attempt ${attempt} failed for ${supplierId}:`, error);
+       if (attempt === retries) throw error;
+       await sleep(1000 * attempt); // Exponential backoff
+     }
+   }
+ }
```

#### Modified File: `src/services/inventory-cache.ts`

```diff
// inventory-cache.ts

- function updateCache(data: InventoryData) {
-   cache.set(data.productId, data.quantity);
- }
+ function updateCache(data: InventoryData) {
+   // Only update when new data is more recent
+   const existing = cache.get(data.productId);
+   if (!existing || data.timestamp > existing.timestamp) {
+     cache.set(data.productId, {
+       quantity: data.quantity,
+       timestamp: data.timestamp,
+       syncStatus: 'success'
+     });
+     console.log(`Cache updated for ${data.productId}: ${data.quantity}`);
+   }
+ }
