Invalid messages are logged as errors but don't crash the component.\n\n### Sending Data\n```javascript\nwindow.postMessage({\n type: 'data',\n data: {\n span_id: 'unique-id',\n input: 'Some input text',\n output: 'Some output text',\n expected: 'Expected result',\n metadata: { additional: 'info' }\n }\n}, '*');\n```\n\n### Changing Settings\n```javascript\nwindow.postMessage({\n type: 'settings',\n settings: {\n theme: 'dark',\n readOnly: true\n }\n}, '*');\n```\n\n## Data Handling\n\n- **Flexible types**: All data fields accept any type (string, number, boolean, object, array)\n- **Safe rendering**: Complex objects are JSON.stringify'd, primitives are converted to strings\n- **Null handling**: Null and undefined values display as \"null\"\n- **Truncation**: Long content is truncated with hover tooltips showing full content\n\n## Sample Data\n\nThe component includes sample data on load:\n- ID: initial-sample\n- Input: \"An orphaned boy discovers he's a wizard on his 11th birthday...\"\n- Output: \"Harry Potter and the Philosopher's Stone\"\n- Expected: \"Harry Potter and the Sorcerer's Stone\"\n- Metadata: null\n\n## Project Structure\n\n```\n├── backend/\n│ └── index.ts # Hono server for serving files\n├── frontend/\n│ ├── components/\n│ │ └── SpanTable.tsx # Main table component\n│ └── index.html # Demo page with test messages\n└── README.md\n```\n\n## API Endpoints\n\n- `GET /` - Serves the main demo page\n- `GET /frontend/*` - Serves frontend static files\n- `POST /api/send-message` - Test endpoint for message sending\n- `GET /api/health` - Health check endpoint\n\n## Development\n\nThe demo page automatically sends test messages to demonstrate the component functionality:\n1. Initial sample data loads immediately\n2. After 1 second: Additional test data with various data types\n3. After 3 seconds: Theme switches to dark mode\n\n## Dependencies\n\n- React 18.2.0\n- Zod for schema validation\n- Tailwind CSS for styling\n- Hono for the backend server","children",[],[170],"9b599df4-9f1e-11f0-9d94-0224a6c84d84","test-messages.js","9b599eb2-9f1e-11f0-9d94-0224a6c84d84",["D",1759361425260],"script","// Test script to send various message types to the SpanTable component\n// Run this in the browser console when the table is loaded\n\n// Test data message with various data types\nfunction sendTestData() {\n window.postMessage({\n type: 'data',\n data: {\n span_id: 'test-' + Date.now(),\n input: 'Test input with timestamp: ' + new Date().toISOString(),\n output: Math.random() > 0.5 ?
