  - Automatic cache integration
  - Error handling
  - Path normalization
  - Support for multiple auth methods

### 5. Cache Manager 🗄️

- **Capabilities**:
  - localStorage-based persistence
  - Size calculation and enforcement
  - Age-based expiration
  - LRU eviction when quota exceeded
  - Cleanup of expired entries
  - Statistics collection
- **Methods**:
  - `get<T>(key)` - Retrieve with expiration check
  - `set<T>(key, data)` - Store with size calculation
  - `has(key)` - Check existence
  - `delete(key)` - Remove entry
  - `clear()` - Remove all entries
  - `getStats()` - Get cache statistics
  - `cleanup()` - Remove expired entries

### 6. Settings UI 🎛️
- **Location**: `src/components/Settings.tsx`
- **Features**:
  - Modal overlay interface
  - Real-time cache statistics
  - Form validation
  - Immediate save and apply
  - Responsive design

### 7. Search UI 🔎
- **Location**: `src/components/PathSearch.tsx`
- **Features**:
  - Base path configuration
  - Search term input with Enter key support
  - Loading spinner during search
  - Search statistics (results count, time taken)
  - Clickable results for secrets
  - Visual distinction of directories vs secrets
  - Depth indicator for each result
  - Helpful search tips

## 🎨 UI/UX Enhancements

### Dashboard Updates
- Added action button group (Search, Settings, Logout)
- Toggle search panel visibility
- Integrated settings modal
- Improved responsive layout

### Visual Feedback
- Loading states for all async operations
- Progress indicators during search
- Success/error messages
- Cache statistics display
- Search result highlighting

## 🔒 Security Features

### Data Protection
- ✅ Credentials never cached or persisted
- ✅ Only in-memory storage during session
- ✅ Server configurations saved securely
- ✅ Cache can be manually cleared
- ⚠️ Cached data includes secret values (cleared on logout recommended)

### DDoS Prevention
- ✅ Configurable cache prevents repeat API calls
- ✅ Search depth limits prevent runaway recursion
- ✅ Result limits prevent memory exhaustion
- ✅ Automatic size enforcement prevents quota issues

## 📊 Performance Optimizations

### Caching Strategy
1. **Cache Hit**: Instant response from localStorage
2. **Cache Miss**: API call + cache storage
3. **Cache Expiration**: Automatic refresh after configured time
4. **Cache Eviction**: LRU algorithm when size limit reached

### Search Optimization
1. **Early Exit**: Stops at max results or depth
2. **Parallel Operations**: Could be enhanced with Promise.all
3. **Progress Feedback**: Non-blocking UI
4. **Cached Paths**: Subsequent searches of same paths are instant

## 🧪 Testing Recommendations

### Manual Testing Checklist
- [ ] Add/remove vault servers
- [ ] Connect with token auth
- [ ] Read a secret directly
- [ ] Perform recursive search
- [ ] Verify cache hit (check console logs)
- [ ] Adjust cache settings
- [ ] Clear cache
- [ ] View cache statistics
- [ ] Test search depth limits
- [ ] Test result limits
- [ ] Test with expired cache
- [ ] Test with full localStorage
- [ ] Test responsive design
- [ ] Test logout (clears session but not cache)

### Edge Cases to Test
- [ ] Search with no results
- [ ] Search at max depth
- [ ] Search at max results
- [ ] Very large cache size
- [ ] Very small cache size
- [ ] Cache expiration edge cases
- [ ] localStorage quota exceeded
