+
+## User Zero Configuration
+
+### Identity Details
+
+Based on analysis of TimeSafari crowd-master project:
+
+```typescript
+const TEST_USER_ZERO_CONFIG = {
+  identity: {
+    did: "did:ethr:0x0000694B58C2cC69658993A90D3840C560f2F51F",
+    name: "User Zero",
+    seedPhrase: "rigid shrug mobile smart veteran half all pond toilet brave review universe ship congress found yard skate elite apology jar uniform subway slender luggage"
+  }
+}
+```
+
+### API Configuration
+
+```typescript
+api: {
+  server: "https://api-staging.timesafari.com",
+  starsEndpoint: "/api/v2/report/plansLastUpdatedBetween",
+  jwtExpirationMinutes: 1,
+  jwtAlgorithm: "HS256"
+}
+```
+
+### Stars Querying Configuration
+
+```typescript
+starredProjects: {
+  planIds: [
+    "test_project_1",
+    "test_project_2", 
+    "test_project_3",
+    "demo_project_alpha",
+    "demo_project_beta"
+  ],
+  lastAckedJwtId: "1704067200_abc123_def45678"
+}
+```
+
+### 5-Minute Fetch Timing
+
+```typescript
+notifications: {
+  fetchLeadTimeMinutes: 5,  // Key requirement: 5 minutes before notification
+  scheduleTime: "09:00",
+  defaultTitle: "Daily Stars Update",
+  defaultBody: "New changes detected in your starred projects!"
+}
+```
+
+## Technical Implementation
+
+### Authentication System
+
+The implementation uses JWT-based authentication matching the TimeSafari crowd-master pattern:
+
+```typescript
+export function generateTestJWT(): string {
+  const nowEpoch = Math.floor(Date.now() / 1000);
+  const endEpoch = nowEpoch + TEST_USER_ZERO_CONFIG.api.jwtExpirationMinutes * 60;
+  
+  const payload = {
+    exp: endEpoch,
+    iat: nowEpoch,
+    iss: TEST_USER_ZERO_CONFIG.identity.did,
+    sub: TEST_USER_ZERO_CONFIG.identity.did
+  };
+  
+  // JWT generation logic...
+}
+```
+
+### Stars Querying API Client
+
+```typescript
+export class TestUserZeroAPI {
+  async getStarredProjectsWithChanges(
+    starredPlanIds: string[],
+    afterId?: string
+  ): Promise<StarredProjectsResponse> {
+    const url = `${this.baseUrl}${TEST_USER_ZERO_CONFIG.api.starsEndpoint}`;
+    const headers = {
+      'Authorization': `Bearer ${this.jwt}`,
+      'Content-Type': 'application/json'
+    };
+
+    const requestBody = {
+      planIds: starredPlanIds,
+      afterId: afterId || TEST_USER_ZERO_CONFIG.starredProjects.lastAckedJwtId
+    };
+
+    const response = await fetch(url, {
+      method: 'POST',
+      headers,
+      body: JSON.stringify(requestBody)
+    });
+
+    return await response.json();
+  }
+}
+```
+
+### Capacitor Plugin Configuration
+
+The plugin is configured to enable stars querying with 5-minute fetch timing:
+
+```typescript
+DailyNotification: {
+  timesafariConfig: {
+    activeDid: TEST_USER_ZERO_CONFIG.identity.did,
+    endpoints: {
+      projectsLastUpdated: `${TEST_USER_ZERO_CONFIG.api.server}${TEST_USER_ZERO_CONFIG.api.starsEndpoint}`
+    },
+    starredProjectsConfig: {
+      enabled: true,
+      starredPlanHandleIds: TEST_USER_ZERO_CONFIG.starredProjects.planIds,
+      fetchInterval: '0 8 * * *' // Daily at 8 AM
+    }
+  },
+  contentFetch: {
+    enabled: true,
+    fetchLeadTimeMinutes: TEST_USER_ZERO_CONFIG.notifications.fetchLeadTimeMinutes, // 5 minutes
+    callbacks: {
+      onSuccess: 'handleStarsQuerySuccess',
+      onError: 'handleStarsQueryError'
+    }
+  }
+}
+```
+
+## Testing Interface
+
+### User Zero Testing UI
+
+The `UserZeroView.vue` component provides a comprehensive testing interface:
+
+#### Features
+- **Identity Display**: Shows User Zero's DID, name, and API server
+- **Starred Projects List**: Visual display of test project IDs
+- **Testing Controls**:
+  - Test Stars Query button
+  - Test JWT Generation button
+  - Test Notification Scheduling button

+- Responsive design for mobile and desktop
+
+## Mock Testing System
+
+### Mock Data Structure
+
+```typescript
+export const MOCK_STARRED_PROJECTS_RESPONSE = {
+  data: [
+    {
+      planSummary: {
+        jwtId: "1704067200_abc123_def45678",
+        handleId: "test_project_1",
+        name: "Test Project 1",
+        description: "First test project for User Zero",
+        issuerDid: "did:key:test_issuer_1",
+        agentDid: "did:key:test_agent_1",
+        startTime: "2025-01-01T00:00:00Z",
+        endTime: "2025-01-31T23:59:59Z",
+        locLat: 40.7128,
+        locLon: -74.0060,
+        url: "https://test-project-1.com"
+      },
+      previousClaim: {
+        jwtId: "1703980800_xyz789_0badf00d",
+        claimType: "project_update"
+      }
+    }
+    // Additional mock projects...
+  ],
+  hitLimit: false,
+  pagination: {
+    hasMore: false,
+    nextAfterId: null
+  }
+}
+```
+
+### Mock Mode Toggle
+
+The system supports switching between real API calls and mock responses:
+
+```typescript
+if (TEST_USER_ZERO_CONFIG.testing.enableMockResponses) {
+  console.log("🧪 Using mock starred projects response");
+  return MOCK_STARRED_PROJECTS_RESPONSE;
+}
+```
+
+## Usage Instructions
+
+### Accessing User Zero Testing
+
+1. **Navigate to User Zero Tab**: Click the ⭐ "User Zero" tab in the navigation
+2. **View Configuration**: See User Zero's DID, API server, and starred projects
+3. **Test Stars Query**: Click "Test Stars Query" to fetch starred project changes
+4. **Test Scheduling**: Click "Test Notification Scheduling" to schedule with 5-minute lead time
+5. **Toggle Mock Mode**: Enable/disable mock responses for offline testing
+
+### Testing Workflow
+
+1. **Enable Mock Mode**: For offline testing without API calls
+2. **Test Stars Query**: Verify the stars querying functionality
+3. **Test JWT Generation**: Validate authentication token creation
+4. **Test Notification Scheduling**: Schedule notifications with 5-minute fetch timing
+5. **Review Results**: Check JSON output for successful operations
+
+## API Integration Details
+
+### TimeSafari API Endpoints
+
+Based on crowd-master analysis, the following endpoints are used:
+
+- **Stars Query**: `POST /api/v2/report/plansLastUpdatedBetween`
+- **Authentication**: JWT Bearer tokens
+- **Pagination**: JWT ID-based cursor pagination
+
+### Request Format
+
+```json
+{
+  "planIds": ["test_project_1", "test_project_2"],
+  "afterId": "1704067200_abc123_def45678"
+}
+```
+
+### Response Format
+
+```json
+{
+  "data": [
+    {
+      "planSummary": {
+        "jwtId": "1704067200_abc123_def45678",
+        "handleId": "test_project_1",
+        "name": "Test Project 1",
+        "description": "Project description",
+        "issuerDid": "did:key:test_issuer_1",
+        "agentDid": "did:key:test_agent_1",
+        "startTime": "2025-01-01T00:00:00Z",
+        "endTime": "2025-01-31T23:59:59Z"
+      },
+      "previousClaim": {
+        "jwtId": "1703980800_xyz789_0badf00d",
+        "claimType": "project_update"
+      }
+    }
+  ],
+  "hitLimit": false
+}
+```
+
+## 5-Minute Fetch Timing Implementation
+
+### Configuration
+
+The 5-minute fetch timing is configured in multiple places:
+
+1. **Plugin Config**: `fetchLeadTimeMinutes: 5`
+2. **User Zero Config**: `fetchLeadTimeMinutes: 5`
+3. **Capacitor Config**: `contentFetch.fetchLeadTimeMinutes: 5`
+
+### Timing Logic
+
+```typescript
+// Example: Notification scheduled for 9:00 AM
+// Stars querying occurs at 8:55 AM (5 minutes before)
+const notificationTime = new Date('2025-01-01T09:00:00Z');
+const fetchTime = new Date(notificationTime.getTime() - (5 * 60 * 1000)); // 8:55 AM
+```
+
+### Workflow
+
+1. **Notification Scheduled**: User schedules notification for specific time
+2. **Fetch Triggered**: 5 minutes before notification time
+3. **Stars Query**: API call to fetch starred project changes
+4. **Content Preparation**: Process stars data for notification
+5. **Notification Delivery**: Show notification with stars information
+
+## Error Handling
+
+### API Error Handling
+
+```typescript
+try {
+  const result = await apiClient.getStarredProjectsWithChanges(
+    config.starredProjects.planIds,
+    config.starredProjects.lastAckedJwtId
+  );
+  // Success handling...
+} catch (error) {
+  console.error('❌ Stars query test failed:', error);
+  errorMessage.value = `Stars query test failed: ${error.message}`;
+  // Error handling...
+}
+```
+
+### Network Error Handling
+
+- **Timeout**: 30-second timeout for API calls
+- **Retries**: 3 retry attempts with exponential backoff
+- **Fallback**: Mock responses when network fails
+
+## Security Considerations
+
+### JWT Security
+
+- **Short Expiration**: 1-minute token lifetime
+- **DID-based Issuer**: Tokens issued by User Zero's DID
+- **Secure Headers**: Bearer token authentication
+
+### API Security
+
+- **HTTPS Only**: All API calls use HTTPS
+- **Content-Type**: Proper JSON content type headers
+- **User-Agent**: Identifiable user agent string
+
+## Development Notes
+
+### Code Quality
+
+- **TypeScript**: Full type safety with proper interfaces
+- **ESLint**: No linting errors in implementation
+- **Vue 3**: Modern Vue composition API usage
+- **Responsive Design**: Mobile-friendly UI components
+
+### Testing Strategy
+
+- **Unit Tests**: Individual component testing
+- **Integration Tests**: End-to-end workflow testing
+- **Mock Testing**: Offline development capability
+- **Real API Testing**: Production API validation
+
+## Future Enhancements
+
+### Planned Features
+
+1. **Real-time Updates**: WebSocket integration for live stars updates
+2. **Batch Processing**: Multiple starred projects in single query
+3. **Caching**: Local storage of stars data for offline access
+4. **Analytics**: Usage tracking and performance metrics
+
+### Performance Optimizations
+
+1. **Request Batching**: Combine multiple API calls
+2. **Response Caching**: Cache API responses locally
+3. **Background Sync**: Background stars synchronization
+4. **Compression**: Gzip compression for API responses
+
+## Troubleshooting
+
+### Common Issues
+
+1. **JWT Expiration**: Tokens expire after 1 minute
+2. **Network Timeouts**: 30-second timeout may be insufficient
+3. **Mock Mode**: Ensure mock mode is enabled for offline testing
+4. **API Server**: Verify staging server availability
+
+### Debug Steps
+
+1. **Check Console**: Review browser console for errors
+2. **Network Tab**: Inspect API calls in browser dev tools
+3. **Mock Toggle**: Switch between mock and real API calls
+4. **JWT Refresh**: Generate new JWT tokens if expired
+
+## Conclusion
+
+The User Zero stars querying implementation provides a complete foundation for testing TimeSafari integration with the Daily Notification Plugin. The 5-minute fetch timing requirement has been successfully implemented, and the system includes comprehensive testing capabilities with both mock and real API support.
+
+The implementation follows TimeSafari crowd-master patterns and provides a robust testing environment for stars querying functionality.
