+# WHOOSH Licensing Development Plan
+
+**Date**: 2025-09-01  
+**Branch**: `feature/license-gating-integration`  
+**Status**: Ready for implementation (depends on KACHING Phase 1)  
+**Priority**: MEDIUM - User experience and upselling integration
+
+## Executive Summary
+
+WHOOSH currently has **zero CHORUS licensing integration**. The system operates without license validation, feature gating, or upselling workflows. This plan integrates WHOOSH with KACHING license authority to provide license-aware user experiences and revenue optimization.
+
+## Current State Analysis
+
+### ✅ Existing Infrastructure
+- React-based web application with modern UI components
+- Search and indexing functionality 
+- User authentication and session management
+- API integration capabilities
+
+### ❌ Missing License Integration
+- **No license status display** - Users unaware of their tier/limits
+- **No feature gating** - All features available regardless of license
+- **No upgrade workflows** - No upselling or upgrade prompts
+- **No usage tracking** - No integration with KACHING telemetry
+- **No quota visibility** - Users can't see usage limits or consumption
+
+### Business Impact
+- **Zero upselling capability** - No way to drive license upgrades
+- **No usage awareness** - Customers don't know they're approaching limits
+- **No tier differentiation** - Premium features not monetized
+- **Revenue leakage** - Advanced features available to basic tier users
+
+## Development Phases
+
+### Phase 3A: License Status Integration (PRIORITY 1)
+**Goal**: Display license information and status throughout WHOOSH UI
+
+#### 1. License API Client Implementation
+```typescript
+// src/services/licenseApi.ts
+export interface LicenseStatus {
+  license_id: string;
+  status: 'active' | 'suspended' | 'expired' | 'cancelled';
+  tier: 'evaluation' | 'standard' | 'enterprise';
+  features: string[];
+  max_nodes: number;
+  expires_at: string;
+  quotas: {
+    search_requests: { used: number; limit: number };
+    storage_gb: { used: number; limit: number };
+    api_calls: { used: number; limit: number };
+  };
+  upgrade_suggestions?: UpgradeSuggestion[];
+}
+
+export interface UpgradeSuggestion {
+  reason: string;
+  current_tier: string;
+  suggested_tier: string;
+  benefits: string[];
+  roi_estimate?: string;
+  urgency: 'low' | 'medium' | 'high';
+}
+
+class LicenseApiClient {
+  private baseUrl: string;
+  
+  constructor(kachingUrl: string) {
+    this.baseUrl = kachingUrl;
+  }
+  
+  async getLicenseStatus(licenseId: string): Promise<LicenseStatus> {
+    const response = await fetch(`${this.baseUrl}/v1/license/status/${licenseId}`);
+    if (!response.ok) {
+      throw new Error('Failed to fetch license status');
+    }
+    return response.json();
+  }
+  
+  async getUsageMetrics(licenseId: string): Promise<UsageMetrics> {
+    const response = await fetch(`${this.baseUrl}/v1/usage/metrics/${licenseId}`);
+    return response.json();
+  }
+}
+```
+
+#### Backend Proxy (required in production)
+To avoid exposing licensing endpoints/IDs client-side and to enforce server-side checks, WHOOSH should proxy KACHING via its own backend:
+
+```python
+# backend/app/api/license.py (FastAPI example)
+@router.get("/api/license/status")
+async def get_status(user=Depends(auth)):
+    license_id = await resolve_license_id_for_org(user.org_id)
+    res = await kaching.get(f"/v1/license/status/{license_id}")
+    return res.json()
+
+@router.get("/api/license/quotas")
+async def get_quotas(user=Depends(auth)):
+    license_id = await resolve_license_id_for_org(user.org_id)
+    res = await kaching.get(f"/v1/license/{license_id}/quotas")
+    return res.json()
+```
+
+And in the React client call the WHOOSH backend instead of KACHING directly:
+
+```typescript
+// src/services/licenseApi.ts (frontend)
+export async function fetchLicenseStatus(): Promise<LicenseStatus> {
+  const res = await fetch("/api/license/status")
+  if (!res.ok) throw new Error("Failed to fetch license status")
+  return res.json()
+}
+```
+
+#### 2. License Status Dashboard Component
+```typescript
+// src/components/license/LicenseStatusDashboard.tsx
+interface LicenseStatusDashboardProps {
+  licenseId: string;
+}
+
+export const LicenseStatusDashboard: React.FC<LicenseStatusDashboardProps> = ({ licenseId }) => {
+  const [licenseStatus, setLicenseStatus] = useState<LicenseStatus | null>(null);
+  const [loading, setLoading] = useState(true);
+  
+  useEffect(() => {
+    const fetchLicenseStatus = async () => {
+      try {
+        // In production, call WHOOSH backend proxy endpoints
+        const status = await fetchLicenseStatus();
+        setLicenseStatus(status);
+      } catch (error) {
+        console.error('Failed to fetch license status:', error);
+      } finally {
+        setLoading(false);
+      }
+    };
+    
+    fetchLicenseStatus();
+    // Refresh every 5 minutes
+    const interval = setInterval(fetchLicenseStatus, 5 * 60 * 1000);
+    return () => clearInterval(interval);
+  }, [licenseId]);
+  
+  if (loading) return <div>Loading license information...</div>;
+  if (!licenseStatus) return <div>License information unavailable</div>;
+  
+  return (
+    <div className="license-status-dashboard">
+      <LicenseStatusCard status={licenseStatus} />
+      <QuotaUsageCard quotas={licenseStatus.quotas} />
+      {licenseStatus.upgrade_suggestions?.map((suggestion, idx) => (
+        <UpgradeSuggestionCard key={idx} suggestion={suggestion} />
+      ))}
+    </div>
+  );
+};
+```
+
+#### 3. License Status Header Component
+```typescript
+// src/components/layout/LicenseStatusHeader.tsx
+export const LicenseStatusHeader: React.FC = () => {
+  const { licenseStatus } = useLicenseContext();
+  
+  const getStatusColor = (status: string) => {
+    switch (status) {
+      case 'active': return 'text-green-600';
+      case 'suspended': return 'text-red-600';
+      case 'expired': return 'text-orange-600';
+      default: return 'text-gray-600';
+    }
+  };
+  
+  return (
+    <div className="flex items-center space-x-4 text-sm">
+      <div className={`font-medium ${getStatusColor(licenseStatus?.status || '')}`}>
+        {licenseStatus?.tier?.toUpperCase()} License
+      </div>
+      <div className="text-gray-500">
+        {licenseStatus?.max_nodes} nodes max
+      </div>
+      <div className="text-gray-500">
+        Expires: {new Date(licenseStatus?.expires_at || '').toLocaleDateString()}
+      </div>
+      {licenseStatus?.status !== 'active' && (
+        <button className="bg-blue-600 text-white px-3 py-1 rounded text-xs hover:bg-blue-700">
+          Renew License
+        </button>
+      )}
+    </div>
+  );
+};
+```
+
+### Phase 3B: Feature Gating Implementation (PRIORITY 2)
+**Goal**: Restrict features based on license tier and show upgrade prompts
+
+#### 1. Feature Gate Hook
+```typescript
+// src/hooks/useLicenseFeatures.ts
+export const useLicenseFeatures = () => {
+  const { licenseStatus } = useLicenseContext();
+  
+  const hasFeature = (feature: string): boolean => {
+    return licenseStatus?.features?.includes(feature) || false;
+  };
+  
+  const canUseAdvancedSearch = (): boolean => {
+    return hasFeature('advanced-search');
+  };
+  
+  const canUseAnalytics = (): boolean => {
+    return hasFeature('advanced-analytics');
+  };
+  
+  const canUseBulkOperations = (): boolean => {
+    return hasFeature('bulk-operations');
+  };
+  
+  const getMaxSearchResults = (): number => {
+    if (hasFeature('enterprise-search')) return 10000;
+    if (hasFeature('advanced-search')) return 1000;
+    return 100; // Basic tier
+  };
+  
+  return {
+    hasFeature,
+    canUseAdvancedSearch,
+    canUseAnalytics,
+    canUseBulkOperations,
+    getMaxSearchResults,
+  };
+};
+```
+
+#### 2. Feature Gate Component
+```typescript
+// src/components/license/FeatureGate.tsx
+interface FeatureGateProps {
+  feature: string;
+  children: React.ReactNode;
+  fallback?: React.ReactNode;
+  showUpgradePrompt?: boolean;
+}
+
+export const FeatureGate: React.FC<FeatureGateProps> = ({ 
+  feature, 
+  children, 
+  fallback, 
+  showUpgradePrompt = true 
+}) => {
+  const { hasFeature } = useLicenseFeatures();
+  const { licenseStatus } = useLicenseContext();
+  
+  if (hasFeature(feature)) {
+    return <>{children}</>;
+  }
+  
+  if (fallback) {
+    return <>{fallback}</>;
+  }
+  
+  if (showUpgradePrompt) {
+    return (
+      <UpgradePrompt 
+        feature={feature}
+        currentTier={licenseStatus?.tier || 'unknown'}
+      />
+    );
+  }
+  
+  return null;
+};
+
+// Usage throughout WHOOSH:
+// <FeatureGate feature="advanced-analytics">
+//   <AdvancedAnalyticsPanel />
+// </FeatureGate>
+```
+
+#### 3. Feature-Specific Gates
+```typescript
+// src/components/search/AdvancedSearchFilters.tsx
+export const AdvancedSearchFilters: React.FC = () => {
+  const { canUseAdvancedSearch } = useLicenseFeatures();
+  
+  return (
+    <FeatureGate feature="advanced-search">
+      <div className="advanced-filters">
+        {/* Advanced search filter components */}
+      </div>
+      <UpgradePrompt 
+        feature="advanced-search"
+        message="Unlock advanced search filters with Standard tier"
+        benefits={[
+          "Date range filtering",
+          "Content type filters", 
+          "Custom field search",
+          "Saved search queries"
+        ]}
+      />
+    </FeatureGate>
+  );
+};
+```
+
+### Phase 3C: Quota Monitoring & Alerts (PRIORITY 3)
+**Goal**: Show usage quotas and proactive upgrade suggestions
+
+#### 1. Quota Usage Components
+```typescript
+// src/components/license/QuotaUsageCard.tsx
+interface QuotaUsageCardProps {
+  quotas: LicenseStatus['quotas'];
+}
+
+export const QuotaUsageCard: React.FC<QuotaUsageCardProps> = ({ quotas }) => {
+  const getUsagePercentage = (used: number, limit: number): number => {
+    return Math.round((used / limit) * 100);
+  };
+  
+  const getUsageColor = (percentage: number): string => {
+    if (percentage >= 90) return 'bg-red-500';
+    if (percentage >= 75) return 'bg-yellow-500';
+    return 'bg-green-500';
+  };
+  
+  return (
+    <div className="quota-usage-card bg-white rounded-lg shadow p-6">
+      <h3 className="text-lg font-semibold mb-4">Usage Overview</h3>
+      
+      {Object.entries(quotas).map(([key, quota]) => {
+        const percentage = getUsagePercentage(quota.used, quota.limit);
+        
+        return (
+          <div key={key} className="mb-4">
+            <div className="flex justify-between text-sm font-medium">
+              <span>{key.replace('_', ' ').toUpperCase()}</span>
+              <span>{quota.used.toLocaleString()} / {quota.limit.toLocaleString()}</span>
+            </div>
+            <div className="w-full bg-gray-200 rounded-full h-2 mt-1">
+              <div 
+                className={`h-2 rounded-full ${getUsageColor(percentage)}`}
+                style={{ width: `${percentage}%` }}
+              />
+            </div>
+            {percentage >= 80 && (
+              <div className="text-xs text-orange-600 mt-1">
+                ⚠️ Approaching limit - consider upgrading
+              </div>
+            )}
+          </div>
+        );
+      })}
+    </div>
+  );
+};
+```
+
+#### 2. Upgrade Suggestion Component
+```typescript
+// src/components/license/UpgradeSuggestionCard.tsx
+interface UpgradeSuggestionCardProps {
+  suggestion: UpgradeSuggestion;
+}
+
+export const UpgradeSuggestionCard: React.FC<UpgradeSuggestionCardProps> = ({ suggestion }) => {
+  const getUrgencyColor = (urgency: string): string => {
+    switch (urgency) {
+      case 'high': return 'border-red-500 bg-red-50';
+      case 'medium': return 'border-yellow-500 bg-yellow-50';
+      default: return 'border-blue-500 bg-blue-50';
+    }
+  };
+  
+  return (
+    <div className={`upgrade-suggestion border-l-4 p-4 rounded ${getUrgencyColor(suggestion.urgency)}`}>
+      <div className="flex items-center justify-between">
+        <div>
+          <h4 className="font-semibold">{suggestion.reason}</h4>
+          <p className="text-sm text-gray-600 mt-1">
+            Upgrade from {suggestion.current_tier} to {suggestion.suggested_tier}
+          </p>
+          {suggestion.roi_estimate && (
+            <p className="text-sm font-medium text-green-600 mt-1">
+              Estimated ROI: {suggestion.roi_estimate}
+            </p>
+          )}
+        </div>
+        <button 
+          className="bg-blue-600 text-white px-4 py-2 rounded hover:bg-blue-700"
+          onClick={() => handleUpgradeRequest(suggestion)}
+        >
+          Upgrade Now
+        </button>
+      </div>
+      
+      <div className="mt-3">
+        <p className="text-sm font-medium">Benefits:</p>
+        <ul className="text-sm text-gray-600 mt-1">
+          {suggestion.benefits.map((benefit, idx) => (
+            <li key={idx} className="flex items-center">
+              <span className="text-green-500 mr-2">✓</span>
+              {benefit}
+            </li>
+          ))}
+        </ul>
+      </div>
+    </div>
+  );
+};
+```
+
+### Phase 3D: Self-Service Upgrade Workflows (PRIORITY 4)
+**Goal**: Enable customers to upgrade licenses directly from WHOOSH
+
+#### 1. Upgrade Request Modal
+```typescript
+// src/components/license/UpgradeRequestModal.tsx
+export const UpgradeRequestModal: React.FC = () => {
+  const [selectedTier, setSelectedTier] = useState<string>('');
+  const [justification, setJustification] = useState<string>('');
+  
+  const handleUpgradeRequest = async () => {
+    const request = {
+      current_tier: licenseStatus?.tier,
+      requested_tier: selectedTier,
+      justification,
+      usage_evidence: await getUsageEvidence(),
+      contact_email: userEmail,
+    };
+    
+    // Send to KACHING upgrade request endpoint
+    await licenseApi.requestUpgrade(request);
+    
+    // Show success message and close modal
+    showNotification('Upgrade request submitted successfully!');
+  };
+  
+  return (
+    <Modal>
+      <div className="upgrade-request-modal">
+        <h2>Request License Upgrade</h2>
+        
+        <TierComparisonTable 
+          currentTier={licenseStatus?.tier}
+          highlightTier={selectedTier}
+          onTierSelect={setSelectedTier}
+        />
+        
+        <textarea 
+          placeholder="Tell us about your use case and why you need an upgrade..."
+          value={justification}
+          onChange={(e) => setJustification(e.target.value)}
+          className="w-full p-3 border rounded"
+        />
+        
+        <UsageEvidencePanel licenseId={licenseStatus?.license_id} />
+        
+        <div className="flex justify-end space-x-3 mt-6">
+          <button onClick={onClose}>Cancel</button>
+          <button 
+            onClick={handleUpgradeRequest}
+            className="bg-blue-600 text-white px-6 py-2 rounded"
+          >
+            Submit Request
+          </button>
+        </div>
+      </div>
+    </Modal>
+  );
+};
+```
+
+#### 2. Contact Sales Integration
+```typescript
+// src/components/license/ContactSalesWidget.tsx
+export const ContactSalesWidget: React.FC = () => {
+  const { licenseStatus } = useLicenseContext();
+  
+  const generateSalesContext = () => ({
+    license_id: licenseStatus?.license_id,
+    current_tier: licenseStatus?.tier,
+    usage_summary: getUsageSummary(),
+    pain_points: identifyPainPoints(),
+    upgrade_urgency: calculateUpgradeUrgency(),
+  });
+  
+  return (
+    <div className="contact-sales-widget">
+      <h3>Need a Custom Solution?</h3>
+      <p>Talk to our sales team about enterprise features and pricing.</p>
+      
+      <button 
+        onClick={() => openSalesChat(generateSalesContext())}
+        className="bg-green-600 text-white px-4 py-2 rounded"
+      >
+        Contact Sales
+      </button>
+      
+      <div className="text-xs text-gray-500 mt-2">
+        Your usage data will be shared to provide personalized recommendations
+      </div>
+    </div>
+  );
+};
+```

+- Quota usage accuracy (target: 100% data integrity)
+
+## Dependencies
+
+- **KACHING Phase 1 Complete**: Requires license server with quota APIs
+- **User Authentication**: Must identify users to fetch license status
+- **Usage Tracking**: Requires instrumentation to measure quota consumption
+
+## Security Considerations
+
+1. **License ID Protection**: Never expose license keys/IDs in client-side code; resolve license_id server-side
+2. **API Authentication**: Secure backend→KACHING with service credentials; frontend talks only to WHOOSH backend
+3. **Feature Bypass Prevention**: Enforce entitlements server-side for any sensitive operations
+4. **Usage Data Privacy**: Comply with data protection regulations for usage tracking
+
+This plan transforms WHOOSH from license-unaware to a comprehensive license-integrated experience that drives revenue optimization and user satisfaction.

+ * Key Features:
+ * - Server-side feature validation for security
+ * - Customizable fallback content for restricted features
+ * - Intelligent upgrade prompts with ROI messaging
+ * - Graceful degradation for license API failures
+ * - Loading state handling during feature checks
+ * 
+ * Business Logic:
+ * - Prevents access to premium features for lower tiers
+ * - Converts feature restrictions into upgrade opportunities
+ * - Provides clear value proposition for restricted features
+ * - Tracks feature gate interactions for business intelligence
+ * 
+ * Security Model:
+ * - All feature validation happens server-side
+ * - Client-side gates are UX enhancement only
+ * - Backend APIs enforce feature restrictions independently
+ * - No sensitive license data exposed to frontend

+/**
+ * License Status Header Component
+ * 
+ * This component provides always-visible license information in the application header.
+ * It serves as the primary touchpoint for license awareness and upgrade discovery.
+ * 
+ * Key Features:
+ * - Prominent tier display with color coding
+ * - Quick quota overview with visual indicators
+ * - Expiration warnings and renewal prompts
+ * - Direct upgrade call-to-action for limited tiers
+ * - Responsive design for all screen sizes
+ * 
+ * Business Logic:
+ * - Builds license awareness by making tier info constantly visible
+ * - Drives upgrade conversions through strategic placement
+ * - Provides early warning for expiration and limit issues
+ * - Creates trust through transparent license information
+ * 
+ * UX Considerations:
+ * - Non-intrusive but informative design
+ * - Color-coded status indicators for quick recognition
+ * - Hover tooltips for detailed information
+ * - Mobile-responsive layout

+ * License Features Hook
+ * 
+ * This custom hook provides comprehensive feature availability checking functionality.
+ * It serves as the primary interface for components to determine what features
+ * are available to the current user based on their license tier.
+ * 
+ * Key Features:
+ * - Comprehensive feature availability checking
+ * - Tier-based capability limits (search results, storage, etc.)
+ * - Real-time quota usage monitoring
+ * - Smart upgrade suggestions based on usage patterns
+ * - Performance optimized with intelligent caching
+ * 
+ * Business Logic:
+ * - Enforces license-based feature restrictions
+ * - Provides data for upgrade conversion optimization
+ * - Tracks feature usage for business intelligence
+ * - Enables tier-appropriate user experiences
+ * 
+ * Security:
+ * - Client-side checks are UX optimization only
+ * - All enforcement happens server-side in API calls
+ * - Feature flags provide graceful degradation
