Step 1: Import Services in AppComponent

File: src/app.component.ts

Add import for ClientCacheService
Add import for PerformanceProfilerService
Add import for NotePreloaderService
Add import for NavigationService
Verify imports compile without errors

import { ClientCacheService } from './services/client-cache.service';
import { PerformanceProfilerService } from './services/performance-profiler.service';
import { NotePreloaderService } from './services/note-preloader.service';
import { NavigationService } from './services/navigation.service';

Step 2: Import Performance Monitor Component

File: src/app.component.ts

Add import for PerformanceMonitorPanelComponent
Add component to @Component imports array
Verify component compiles

import { PerformanceMonitorPanelComponent } from './components/performance-monitor-panel/performance-monitor-panel.component';

@Component({
  imports: [
    // ... existing imports
    PerformanceMonitorPanelComponent,
  ]
})

Step 3: Add Performance Monitor to Template

File: src/app.component.simple.html

Add performance monitor component at end of template
Verify template compiles

<!-- Performance monitoring panel (dev only) -->
<app-performance-monitor-panel></app-performance-monitor-panel>

Step 4: Integrate Preloading in Note Viewer

File: Note viewer component (e.g., note-viewer.component.ts)

Inject ClientCacheService
Inject NotePreloaderService
Inject NavigationService
Update loadNote() method to use cache
Add preloading call after loading note
Verify component compiles

private cache = inject(ClientCacheService);
private preloader = inject(NotePreloaderService);
private navigation = inject(NavigationService);

async loadNote(noteId: string) {
  // Try cache first
  const cached = this.cache.get<NoteContent>(`note_${noteId}`);
  if (cached) {
    this.displayNote(cached);
    return;
  }

  // Load from server
  const note = await this.http.get<NoteContent>(`/api/files/${noteId}`).toPromise();
  this.displayNote(note);

  // Cache it
  this.cache.setMemory(`note_${noteId}`, note);

  // Preload adjacent notes
  const context = this.navigation.getCurrentContext(noteId);
  this.preloader.preloadAdjacent(noteId, context);
}

Step 5: Add Cleanup Interval

File: src/app.component.ts in ngOnInit()

Inject NotePreloaderService
Add cleanup interval (5 minutes)
Verify no compilation errors

ngOnInit() {
  // ... existing initialization

  // Cleanup caches every 5 minutes
  setInterval(() => {
    this.preloader.cleanup();
  }, 5 * 60 * 1000);
}

Step 6: Compilation & Build

Run npm run build successfully
No TypeScript errors
No template errors
No console warnings
Build size acceptable (< 5% increase)

Step 7: Run Tests

Run npm test -- --include='**/phase4.spec.ts'
All tests pass ✅
No test failures
No test warnings
Coverage acceptable (> 80%)

Expected Output:

✓ ClientCacheService (6 tests)
✓ PerformanceProfilerService (7 tests)
✓ NotePreloaderService (6 tests)
✓ NavigationService (4 tests)
✓ Integration Tests (3 tests)

TOTAL: 26 tests passing

Step 8: Development Testing

Start dev server: npm start
Open browser to http://localhost:4200
Performance panel visible in bottom-right
No console errors
Navigate between notes
Verify cache statistics updating
Verify preloader status showing

Manual Testing Checklist

Click on a note - loads from server
Click on same note again - loads from cache (instant)
Navigate to adjacent notes - preloaded (instant)
Performance panel shows cache hits
Performance panel shows preloader activity
No memory leaks (memory stable)
No console errors

Step 9: Performance Verification

Check Cache Statistics

// In browser console
const cache = ng.probe(document.querySelector('app-root')).injector.get(ClientCacheService);
console.log(cache.getStats());
// Expected: memory size > 0, persistent size > 0

Memory cache has items
Persistent cache has items
Cache sizes within limits

Check Preloader Status

const preloader = ng.probe(document.querySelector('app-root')).injector.get(NotePreloaderService);
console.log(preloader.getStatus());
// Expected: queueSize >= 0, loadingCount <= maxConcurrentLoads

Queue size reasonable
Loading count within limits
Configuration correct

Check Performance Metrics

const profiler = ng.probe(document.querySelector('app-root')).injector.get(PerformanceProfilerService);
console.log(profiler.exportMetrics());
// Expected: avgDuration < 100ms for cached operations

Navigation time < 100ms for cached notes
Cache operations < 5ms
No slow operations

Step 10: Configuration Tuning

Review current configuration
Identify optimization opportunities
Adjust preload distance if needed
Adjust concurrent loads if needed
Adjust cache TTL if needed
Test configuration changes
Verify performance improvements

Configuration Checklist

// Verify current settings
preloader.setConfig({
  preloadDistance: 2,        // Adjust as needed
  maxConcurrentLoads: 3      // Adjust as needed
});

cache.setMemory(key, value, 30 * 60 * 1000); // 30 minutes TTL

Preload distance appropriate for use case
Concurrent loads not overwhelming server
Cache TTL appropriate for content update frequency

Step 11: Production Build

Run npm run build:prod
Build completes successfully
No errors or warnings
Build size acceptable
Performance panel hidden in production

Step 12: Staging Deployment

Deploy to staging environment
Verify all features working
Monitor performance metrics
Check for errors in logs
Verify cache hit rate > 70%
Verify navigation time < 100ms
Verify memory usage stable
Verify server load reduced

Staging Monitoring (30 minutes)

Monitor cache statistics
Monitor preloader status
Monitor performance metrics
Check for memory leaks
Verify no console errors
Verify smooth navigation

Step 13: Documentation Review

Quick start guide reviewed
Implementation guide reviewed
Configuration guide reviewed
Team trained on features
Support documentation ready
Troubleshooting guide available

Step 14: Rollback Plan

Rollback procedure documented
Rollback tested locally
Team aware of rollback steps
Rollback time < 5 minutes

Rollback Steps

// If issues occur:
1. Disable preloading: preloader.setConfig({ enabled: false })
2. Clear caches: cache.cleanup()
3. Revert configuration to defaults
4. Monitor metrics for recovery

Rollback procedure clear
Team trained on rollback
Rollback tested
