+
+final readonly class LiveComponentService
+{
+    public function __construct(
+        private readonly ComponentMetricsCollector $metricsCollector
+    ) {}
+
+    public function renderComponent(string $componentId): string
+    {
+        $startTime = microtime(true);
+
+        // Render logic
+        $html = $this->renderer->render($componentId);
+

+        $this->metricsCollector->recordRender($componentId, $duration, $cached = false);
+
+        return $html;
+    }
+
+    public function executeAction(string $componentId, string $actionName): array
+    {
+        $startTime = microtime(true);
+
+        try {
+            $result = $this->actionExecutor->execute($componentId, $actionName);
+            $duration = (microtime(true) - $startTime) * 1000;
+
+            $this->metricsCollector->recordAction($componentId, $actionName, $duration, true);
+
+            return $result;
+        } catch (\Exception $e) {
+            $duration = (microtime(true) - $startTime) * 1000;
+            $this->metricsCollector->recordAction($componentId, $actionName, $duration, false);
+
+            throw $e;
+        }
+    }
+}
+```
+
+### Metrics Export
+
+**Summary Statistics**:
+```php
+$summary = $metricsCollector->getSummary();
+// Returns:
+// [
+//     'total_renders' => 150,
+//     'total_actions' => 45,
+//     'cache_hits' => 100,
+//     'cache_misses' => 50,
+//     'total_events' => 30,
+//     'action_errors' => 2,
+//     'avg_render_time_ms' => 25.5,
+//     'avg_action_time_ms' => 15.3,
+//     'cache_hit_rate' => 66.67
+// ]
+```
+
+**Prometheus Export**:
+```php
+$prometheus = $metricsCollector->exportPrometheus();
+// Returns Prometheus-formatted metrics:
+// # HELP LiveComponents metrics
+// # TYPE livecomponent_* counter/histogram
+//
+// livecomponent_renders_total{component_id=user-profile,cached=false} 45.00 1704067200
+// livecomponent_render_duration_ms{component_id=user-profile,cached=false} 25.50 1704067200
+// ...
+```
+
+### Performance Integration
+
+The ComponentMetricsCollector integrates with the Framework's PerformanceCollector:
+
+```php
+$collector = new ComponentMetricsCollector($performanceCollector);
+
+$collector->recordRender('comp-123', 45.5, false);
+// Also records to PerformanceCollector:
+// - Metric name: "livecomponent.render.comp-123"
+// - Category: RENDERING
+// - Duration: 45.5ms
+// - Metadata: ['cached' => false]
+```

+
+// Recording captures:
+// - Action execution times
+// - Component render times
+// - Memory snapshots (every 500ms)
+// - Execution timeline data
+```
+
+**Data Structures**:
+```javascript
+// Performance recording entry
+{
+    type: 'action' | 'render',
+    componentId: 'comp-abc-123',
+    actionName: 'handleClick',  // for actions only
+    duration: 25.5,             // milliseconds
+    startTime: 1000.0,          // performance.now()
+    endTime: 1025.5,            // performance.now()
+    timestamp: 1704067200       // Date.now()
+}
+
+// Memory snapshot
+{
+    timestamp: 1704067200,

+- Positioned at top-left of component element
+
+**Badge Content**:
+```
+⚡ UserProfile (comp-abc1...)
+Actions: 5
+```
+
+**Auto-Management**:
+- Created when component initializes
+- Updated when actions execute
+- Removed when component destroyed
+- Position updates on DOM changes (MutationObserver)
+
+### Keyboard Shortcuts
+
+- **Ctrl+Shift+D**: Toggle DevTools visibility
+
+### DevTools Initialization
+
+**Automatic** (Development only):
+```html
+<html data-env="development">
+    <!-- DevTools automatically initializes -->
+</html>
+```
+
+**Manual**:
+```javascript
+import { LiveComponentDevTools } from './modules/LiveComponentDevTools.js';
+
+const devTools = new LiveComponentDevTools();
+// Auto-initializes if data-env="development"
+```
+
+## Integration with LiveComponent Lifecycle
+
+### Event-Driven Architecture
+
+The Observability system integrates via custom events:
+
+```javascript
+// Component Initialization
+document.dispatchEvent(new CustomEvent('livecomponent:registered', {
+    detail: {
+        componentId: 'comp-abc-123',
+        componentName: 'UserProfile',
+        initialState: { userId: 1, name: 'John' }
+    }
+}));
+
+// Action Execution
+document.dispatchEvent(new CustomEvent('livecomponent:action', {
+    detail: {
+        componentId: 'comp-abc-123',
+        actionName: 'handleClick',
+        startTime: 1000.0,
+        endTime: 1025.5,
+        duration: 25.5,
+        success: true
+    }
+}));
+
+// Component Destruction
+document.dispatchEvent(new CustomEvent('livecomponent:destroyed', {
+    detail: {
+        componentId: 'comp-abc-123'
+    }
+}));
+```
+
+### Backend Integration
+
+```php
+// In LiveComponent implementation
+final class UserProfileComponent
+{
+    public function __construct(
+        private readonly ComponentMetricsCollector $metrics
+    ) {}
+
+    public function render(): string
+    {
+        $start = microtime(true);
+
+        $html = $this->renderTemplate();
+
+        $duration = (microtime(true) - $start) * 1000;
+        $this->metrics->recordRender($this->componentId, $duration, false);
+
+        return $html;
+    }
+
+    public function handleAction(string $actionName): array
+    {
+        $start = microtime(true);
+
+        try {
+            $result = $this->executeAction($actionName);
+
+            $duration = (microtime(true) - $start) * 1000;
+            $this->metrics->recordAction($this->componentId, $actionName, $duration, true);
+
+            return $result;
+        } catch (\Exception $e) {
+            $duration = (microtime(true) - $start) * 1000;
+            $this->metrics->recordAction($this->componentId, $actionName, $duration, false);
+
+            throw $e;
+        }
+    }
+}
+```
+

+
+**Prometheus Integration**: ✅ Full Prometheus format support for external monitoring
+
+### Frontend DevTools
+
+**Memory Usage**:
+- DevTools overlay: ~100KB base
+- Per component: ~2KB in tree
+- Per action log entry: ~500 bytes
+- Performance recording (100 entries): ~50KB
+
+**Performance Impact**:
+- Event listener overhead: <0.01ms per event
+- Badge rendering: <1ms per badge
+- DOM mutation observer: Batched, minimal impact
+- Performance recording: <0.1ms per recording entry
+
+**Data Limits**:
+- Action log: Last 100 entries auto-trimmed
+- Performance recording: Last 100 entries
+- Memory snapshots: Last 100 snapshots
+- Prevents unbounded memory growth
+
+## Best Practices
+
+### Backend Metrics
+
+1. **Selective Recording**: Record only relevant metrics in production
+2. **Batch Operations**: Use batch recording methods for multiple operations
+3. **Regular Reset**: Reset metrics periodically to prevent memory buildup
+4. **Export Strategy**: Export to monitoring systems (Prometheus, Grafana) regularly
+
+### Frontend DevTools
+
+1. **Development Only**: Never enable in production (data-env check)
+2. **Performance Recording**: Use recording only when actively debugging
+3. **Badge Visibility**: Disable badges when not needed to reduce DOM overhead
+4. **Log Management**: Clear logs regularly during long debugging sessions
+5. **Export Data**: Export action logs for offline analysis
+
+### Integration
+
+1. **Event Consistency**: Use standard event names for consistent tracking
+2. **Error Handling**: Always record failed actions with proper error context
+3. **Component Naming**: Use descriptive component names for easier debugging
+4. **Action Granularity**: Keep actions focused and well-named
+
+## Color Scheme (VS Code Dark Theme)
+
+All visualizations use consistent VS Code dark theme colors:
+
+- **Primary Blue** (#569cd6): Component names, borders
+- **Yellow** (#dcdcaa): Actions, metrics, numbers
+- **Green** (#4ec9b0): Success, cache hits, memory reduction
+- **Red** (#f48771): Errors, failures, memory increase
+- **Gray** (#858585): Subdued text, labels
+- **Dark Background** (#1e1e1e): Panels, overlays
+- **Border** (#3c3c3c): Separators, containers
