  const handleUserInteraction = useCallback(async (eventType, payload) => {
    // Track interaction for learning
    await UserInteractionTracker.track({
      eventType,
      payload,
      userContext,
      pageContext: pageData?.metadata,
      timestamp: new Date().toISOString()
    });

    // Update local state
    setInteractionState(prev => ({
      ...prev,
      [payload.insightId]: {
        ...prev[payload.insightId],
        [eventType]: true
      }
    }));

    switch (eventType) {
      case 'reasoning_toggled':
        // Analytics: Track reasoning engagement
        break;
      case 'full_cot_requested':
        // Analytics: Track deep engagement with AI reasoning
        break;
      case 'action_taken':
        // Analytics: Track business action completion
        break;
    }
  }, [pageData, userContext]);

  const handleProposeNewInsight = () => {
    // Opens a modal to submit a new insight
    InsightFeedbackService.promptForNew(pageData?.metadata);
  };

  if (loading) return <PageLoadingState />;
  if (error) return <PageErrorState error={error} onRetry={refetch} />;

  return (
    <div className="dynamic-page">
      {/* EU AI Act Compliance Header */}
      <AIComplianceHeader disclosure={pageData.metadata.aiDisclosure} />
      
      {/* Page Content */}

  const [streamingData, setStreamingData] = useState({});
  
  // Set up streaming connections for real-time updates
  useStreamingUpdates({
    pageId: layout.pageId,
    onUpdate: (componentId, updatedProps) => {
      setStreamingData(prev => ({
        ...prev,
        [componentId]: updatedProps
      }));
    }
  });

  const renderComponent = (item, index) => {
    const Component = componentMap[item.component.type];
    
    if (!Component) {
      return (
        <div key={index} className="component-error">
          <h4>Component Error</h4>
          <p>Component '{item.component.type}' not found.</p>
        </div>
      );
    }

    // Merge static props with streaming updates
    const mergedProps = {
      ...item.component.props,
      ...streamingData[item.id],
      onUserInteraction,
      interactionState: interactionState[item.id] || {}
    };

      </div>
    );
  };

  const gridStyles = {
    display: 'grid',
    gridTemplateColumns: `repeat(${layout.columns}, 1fr)`,
    gap: `${layout.gap * 4}px`,
    transition: 'all 0.3s ease'
  };

  return componentMap[componentKey] || componentMap[type];
};

6. EU AI Act Compliance Components​

      detailLevel: this.inferDetailPreference(interaction),
      reasoningEngagement: this.trackReasoningUsage(interaction),
      actionPatterns: this.trackActionPatterns(interaction)
    };

    localStorage.setItem('userPreferences', JSON.stringify(preferences));
  }
}

8. Automated Insight Validation Engine​

To empower users to collaborate with the AI, the system includes a closed-loop, automated feedback engine. This allows users to suggest edits to existing insights or propose new ones, which the system then validates and integrates autonomously.

8.1. User Experience​

  • Suggesting Edits: A "Suggest a Change" button in the ReasoningPanel allows users to submit corrections or rephrasing for an existing insight.
  • Proposing New Insights: A floating action button on the DynamicPage allows users to submit a completely new insight or decision based on their own observations.

8.2. Backend: The Multi-Step Validation Workflow​

When a user submits feedback via the POST /api/insights/feedback endpoint, the Insight Validation Service triggers a sophisticated, multi-step cognitive loop.

Step 1: Intent Parsing & Entity Extraction The engine uses an LLM to parse the user's raw text to understand their intent (e.g., 'escalate_urgency', 'correct_data') and extract key entities and new information.

Step 2: Automated Fact-Checking & Context Retrieval (RAG) The engine uses the extracted entities to query the RAG microservice. The RAG service searches all connected data sources (PostgreSQL, internal documents, external news APIs) to find evidence that supports or refutes the user's claim.

Step 3: Impact Analysis & Re-Reasoning The engine performs a second, complex LLM call, providing the original insight, the user's suggestion, the retrieved evidence, and the company's strategic objectives. It instructs the LLM to generate a revised insight and, crucially, to analyze its impact on strategic goals.

Step 4: Automated Action & UI Update Based on the LLM's final recommendation, the engine takes one of three actions:

  • APPLY_CHANGE: If the change is valid and has a positive or neutral impact, the insight is updated in the database and pushed to the user's UI in real-time.
  • FLAG_NEGATIVE_IMPACT: If the change is valid but has a negative impact on key objectives, the change is not applied. Instead, a new "warning" insight is generated and displayed, explaining the negative trade-off. This provides critical safety and transparency.
  • REJECT_INVALID: If the user's claim could not be verified, a polite notification is displayed to the user, and the original insight is retained.

This automated workflow transforms user feedback from a simple comment into a trigger for a full, AI-driven validation and impact analysis cycle.

9. Strategic Considerations & Refinements​

This FSD is a fantastic foundation. As you move toward implementation, here are a few strategic refinements to consider that build upon this base.

9.1. Integrating Interactivity and State Management​

The current specification excels at rendering a page layout. The next step is to define how these dynamically rendered components become interactive.

  • How do widgets communicate? For example, clicking a metric in the PerformanceSummaryWidget might need to update or filter another widget on the page.

  • Recommendation: Consider extending the JSON schema to support an event and action system. The backend could define actions in the props, like:

    "primaryAction": {
      "text": "Refresh Performance",
      "action": {
        "type": "BROADCAST_EVENT",
        "payload": { "eventName": "REFRESH_PERFORMANCE_DATA" }
      }
    }

    The DynamicPage component could then manage a shared state or event bus, listening for these events and triggering the appropriate data refetches or UI updates.

9.2. Incorporating the Streaming Data Flow​

This rendering engine is the perfect place to receive the streaming data we discussed for the What-If Workbench.

  • How it works: The DynamicPage.jsx component can establish the streaming connection. While the overall page structure is defined by the initial JSON, the props for individual widgets can be updated in real-time by incoming data.

  • Example: The PageRenderer could pass a stream of data down to the PerformanceSummaryWidget. As the Monte Carlo simulation runs, new data packets would be sent, causing the widget to re-render with the latest confidence levels without reloading the entire page.

9.3. Versioning the Schema and Components​

As your application evolves, you will inevitably want to change the props or behavior of a widget.

  • The Challenge: The backend might generate JSON for a CriticalInsightCard_v2 while an older frontend only knows CriticalInsightCard.

  • Recommendation: Introduce a version field into your JSON schema for each component.

    "component": {
      "type": "CriticalInsightCard",
      "version": "1.1",
      "props": { ... }
    }

    The ComponentRegistry.js can then be structured to handle multiple versions, ensuring that new backend features don't break older clients.

10. Implementation Roadmap​

Phase 1: Basic Learning (The MVP Foundation)​

Objective: Get the core feedback loop working. The system should be able to track basic interactions, build a simple user profile, and make elementary changes to the page layout.

Epic 1: Backend - User Profile & Interaction Tracking​

  • Database: Design and implement the database schema for the UserProfile model. Include initial fields for behavioral_patterns and learning_metadata.
  • API Endpoint: Create the backend API endpoint (e.g., POST /api/analytics/interaction) to receive and validate interaction events from the frontend.
  • Interaction Engine: Implement the initial InteractionLearningEngine. Focus on the process_interaction and _update_behavioral_patterns methods. The learning can start with simple weighted averages.
  • Profile Service: Build a service to create, retrieve, and update user profiles.

Epic 2: Backend - Simple Adaptive Generation​

  • Page Generator: Implement the initial AdaptivePageGenerator. It should be able to retrieve a user profile and make a simple decision.
  • Layout Strategy: Implement two basic layout strategies from _determine_layout_strategy, such as 'executive_summary' and 'action_priority'.
  • API Integration: Modify the existing page generation API to use the AdaptivePageGenerator to produce the final page JSON.

Epic 3: Frontend - Instrument User Interactions​

  • Event Tracking: Ensure the UserInteractionTracker service (from your previous FSD) is correctly sending events for reasoning_expanded, insight_dismissed, and action_taken.
  • Payload Enrichment: Add necessary metadata to the event payloads (e.g., complexity_score, time_to_action).

Phase 2: Advanced Patterns (Building Intelligence)​

Objective: Move beyond simple behavioral traits to understand context and content. The system should start making more nuanced and relevant adaptations.

Epic 1: Contextual Pattern Recognition​

  • Data Models: Create database schemas to store contextual_patterns and content_effectiveness scores.
  • Frontend Context: Enhance the frontend to send contextual information with each interaction (e.g., time of day, business period).
  • Learning Engine: Implement the _update_contextual_patterns and _update_content_effectiveness methods in the learning engine.
  • Prediction Logic: Implement the predictive logic in the AdaptivePageGenerator, starting with _predict_detail_preference which uses the new contextual data.

Epic 2: Content Relevance & Personalization​

  • Relevance Scoring: Implement the _calculate_relevance_score method to rank insights based on user profile, context, and historical effectiveness.
  • Insight Processing: Build the _generate_contextual_insights logic that uses relevance scores to select and prioritize the most important content for the user.

Epic 3: Cross-User Learning​

  • Pattern Analyzer: Implement the CrossUserPatternAnalyzer and the find_role_based_patterns method.
  • Scheduled Job: Create a scheduled background job that runs the analyzer periodically (e.g., weekly) to update aggregated role-based patterns.
  • New User Logic: Update the AdaptivePageGenerator to use these role-based patterns as the default profile for new users, giving them a personalized experience from their first session.

Phase 3: Predictive Intelligence (Becoming Proactive)​

Objective: Use outcome data to learn what actually works and begin proactively generating pages before the user even asks for them.

Epic 1: Outcome-Based Feedback Loop​

  • Outcome Tracking: Design and implement a system for capturing business outcomes of actions taken (this is a key product design task). Create an API endpoint (e.g., POST /api/outcomes).
  • Continuous Learning System: Implement the ContinuousLearningSystem and the process_outcome_feedback method.
  • Effectiveness Calculation: Implement the _calculate_page_effectiveness logic to score page sessions based on engagement, success rates, and business impact.

Epic 2: Predictive Page Pre-Generation​

  • Background Worker: Set up a background worker infrastructure.
  • Pre-generation Trigger: Create logic to trigger page pre-generation based on signals like an upcoming S&OP meeting in the user's calendar or typical login times.
  • Caching Layer: Implement a caching layer where pre-generated pages are stored.
  • API Update: Modify the page-load API to check the cache for a pre-generated page before falling back to on-demand generation.

Phase 4: Autonomous Optimization (The Self-Driving System)​

Objective: Create a fully autonomous system that not only adapts to users but actively experiments and improves its own core intelligence over time.

Epic 1: Autonomous System Improvement​

  • Periodic Optimization: Implement the run_periodic_optimization method in the ContinuousLearningSystem.
  • Self-Improving Templates: This job should be able to analyze global patterns and update the default page templates, raising the baseline intelligence for all users.
  • Stale Profile Detection: Implement logic to identify and potentially reset or lower the confidence score for user profiles that haven't been updated in a long time.

Epic 2: Automated A/B Testing of Layouts​

  • Experimentation Logic: Enhance the AdaptivePageGenerator to, for a small fraction of users, generate a "challenger" layout alongside the "champion" layout.
  • Performance Comparison: Enhance the ContinuousLearningSystem to statistically compare the page_effectiveness metrics between champion and challenger layouts.
  • Automated Promotion: Create a mechanism to automatically promote a challenger to the new champion if it proves to be significantly more effective over time.
