## 🔧 Technical Implementation Details

### Component Architecture

```
PackDetailPage (Page)
├── PackTestResult (Display latest)
├── PackTestHistory (Display history)
└── PackTestBadge (Status indicator)

PackRegisterPage (Page)
└── Form with validation
    └── Success/Error alerts
```

### Data Flow

```
User Action → Hook (React Query) → API Call → Response
    ↓
Cache Update (Query Invalidation)
    ↓
UI Re-render (Automatic)
```

### State Management

- **React Query** for server state
- **useState** for local UI state (expanded sections, form data)
- **Query invalidation** for cache updates after mutations

### API Integration

All API calls use temporary fetch-based implementations until the OpenAPI client is regenerated with new endpoints:

```typescript
const response = await fetch(`${BASE_URL}/packs/${ref}/tests`, {
  headers: { Authorization: `Bearer ${token}` }
});
```

### Error Handling

**Pattern**:
1. Try/catch in mutation hooks
2. Error state in components
3. User-friendly error messages
4. Alert components with icons
5. Retry mechanisms (manual)

### Loading States

**Implemented**:
- Spinner during data fetching
- "Running Tests..." button text
- "Loading..." in pagination
- Skeleton states for empty data

5. **Browser Testing**: Test in Chrome, Firefox, Safari

### Future Enhancements (Phase 6)
1. **Real-time Updates**: WebSocket integration for live test execution
2. **Test Comparison**: Compare results across versions
3. **Analytics Dashboard**: Trend charts and metrics
4. **Filtering**: Filter test history by status, date, trigger
5. **Export**: Download test results as CSV/JSON
6. **Notifications**: Browser/email alerts for test failures

---

## 💡 Key Design Decisions

1. **Component Modularity**: Separate components for badge, result, and history for reusability
2. **Expandable UI**: Collapsible sections to reduce visual clutter
3. **React Query**: Server state management for automatic cache updates
4. **Temporary API Calls**: Manual fetch until OpenAPI client regenerated
5. **Status Icons**: Visual + text for accessibility
6. **Form Validation**: Real-time feedback for better UX
7. **Auto-redirect**: 2-second delay allows user to see success message
