+# Error Tracking System Documentation
+
+## Overview
+
+The error tracking system provides comprehensive monitoring and debugging capabilities for ThrillWiki. It captures detailed error context including stack traces, user action breadcrumbs, and environment information.
+
+## Features
+
+### 1. Enhanced Error Context
+
+Every error captured includes:
+- **Stack Trace**: First 5000 characters of the error stack
+- **Breadcrumbs**: Last 10 user actions before the error
+- **Environment Context**: Browser/device information at error time
+- **Request Metadata**: Endpoint, method, duration, status code
+- **User Context**: User ID, session information
+
+### 2. Error Monitoring Dashboard
+
+**Location**: `/admin/error-monitoring`
+
+**Access**: Admin/Moderator with MFA only
+
+**Features**:
+- Real-time error list with auto-refresh (30 seconds)
+- Filter by date range (1h, 24h, 7d, 30d)
+- Filter by error type
+- Search by request ID, endpoint, or error message
+- Error analytics (total errors, error types, affected users, avg duration)
+- Top 5 errors chart
+
+### 3. Error Details Modal
+
+Click any error to view:
+- Full request ID (copyable)
+- Timestamp
+- Endpoint and HTTP method
+- Status code and duration
+- Full error message
+- Stack trace (collapsible)
+- Breadcrumb trail with timestamps
+- Environment context (formatted JSON)
+- Link to user profile (if available)
+- Copy error report button
+
+### 4. User-Facing Error IDs
+
+All errors shown to users include a short reference ID (first 8 characters of request UUID):
+
+```
+Error occurred
+Reference ID: a3f7b2c1
+```
+
+Users can provide this ID to support for quick error lookup.
+
+### 5. Error ID Lookup
+
+**Location**: `/admin/error-lookup`
+
+Quick search interface for finding errors by their reference ID. Enter the 8-character ID and get redirected to the full error details.
+
+## How It Works
+
+### Breadcrumb Tracking
+
+Breadcrumbs are automatically captured for:
+- **Navigation**: Route changes
+- **User Actions**: Button clicks, form submissions
+- **API Calls**: Edge function and Supabase calls
+- **State Changes**: Important state updates
+
+### Environment Context
+
+Captured automatically on error:
+- Viewport dimensions
+- Screen resolution
+- Browser memory usage (Chrome only)
+- Network connection type
+- Timezone and language
+- Platform information
+- Storage availability
+
+### Error Flow
+
+1. **Error Occurs** → Error boundary or catch block
+2. **Context Captured** → Breadcrumbs + environment + stack trace
+3. **Logged to Database** → `request_metadata` table via RPC function
+4. **User Notification** → Toast with error ID
+5. **Admin Dashboard** → Real-time visibility
+
+## Database Schema
+
+### request_metadata Table
+
+New columns added:
+- `error_stack` (text): Stack trace (max 5000 chars)
+- `breadcrumbs` (jsonb): Array of breadcrumb objects
+- `environment_context` (jsonb): Browser/device information
+
+### error_summary View
+
+Aggregated error statistics:
+- Error type and endpoint
+- Occurrence count
+- Affected users count
+- First and last occurrence timestamps
+- Average duration
+- Recent request IDs (last 24h)
+
+## Using the System
+
+### For Developers
+
+#### Adding Breadcrumbs
+
+```typescript
+import { breadcrumb } from '@/lib/errorBreadcrumbs';
+
+// Navigation (automatic via App.tsx)
+breadcrumb.navigation('/parks/123', '/parks');
+
+// User action
+breadcrumb.userAction('clicked submit', 'ParkForm', { parkId: '123' });
+
+// API call
+breadcrumb.apiCall('/functions/v1/detect-location', 'POST', 200);
+
+// State change
+breadcrumb.stateChange('Park data loaded', { parkId: '123' });
+```
+
+#### Error Handling with Tracking
+
+```typescript
+import { handleError } from '@/lib/errorHandler';
+import { trackRequest } from '@/lib/requestTracking';
+
+try {
+  const result = await trackRequest(
+    { endpoint: '/api/parks', method: 'GET' },
+    async (context) => {
+      // Your code here
+      return data;
+    }
+  );
+} catch (error) {
+  handleError(error, {
+    action: 'Load park data',
+    metadata: { parkId },
+  });
+}
+```
+
+### For Support Staff
+
+#### Finding an Error
+
+1. User reports error with ID: `a3f7b2c1`
+2. Go to `/admin/error-lookup`
+3. Enter the ID
+4. View full error details
+
+#### Analyzing Error Patterns
+
+1. Go to `/admin/error-monitoring`
+2. Review analytics cards for trends
+3. Check Top 5 Errors chart
+4. Filter by time range to see patterns
+5. Click any error for full details
+
+## Best Practices
+
+### DO:
+- ✅ Always use error boundaries around risky components
+- ✅ Add breadcrumbs for important user actions
+- ✅ Use `trackRequest` for critical API calls
+- ✅ Include context in `handleError` calls
+- ✅ Check error monitoring dashboard regularly
+
+### DON'T:
+- ❌ Log sensitive data in breadcrumbs
+- ❌ Add breadcrumbs in tight loops
+- ❌ Ignore error IDs in user reports
+- ❌ Skip error context when handling errors
+- ❌ Let errors go untracked
+
+## Performance Considerations
+
+- **Error tracking overhead**: < 10ms per request
+- **Breadcrumb memory**: Max 10 breadcrumbs retained
+- **Stack trace size**: Limited to 5000 characters
+- **Database cleanup**: 30-day retention (automatic)
+- **Dashboard refresh**: Every 30 seconds
+
+## Troubleshooting
+
+### Error not appearing in dashboard
+- Check if error occurred within selected time range
+- Verify error type filter settings
+- Try clearing search term
+- Refresh the dashboard manually
+
+### Missing breadcrumbs
+- Breadcrumbs only captured for last 10 actions
+- Check if breadcrumb tracking is enabled for that action type
+- Verify error occurred after breadcrumbs were added
+
+### Incomplete stack traces
+- Stack traces limited to 5000 characters
+- Some browsers don't provide full stacks
+- Source maps not currently supported
+
+## Limitations
+
+**Not Included**:
+- Third-party error tracking (Sentry, Rollbar)
+- Session replay functionality
+- Source map support for minified code
+- Real-time alerting (future enhancement)
+- Cross-origin error tracking
+- Error rate limiting
+
+## Future Enhancements
+
+- AI-powered error categorization
+- Automatic error assignment to team members
+- GitHub Issues integration
+- Slack/Discord notifications for critical errors
+- Real-time WebSocket updates
+- Error severity auto-detection
+- Error resolution workflow
+
+## Support
+
+For issues with the error tracking system itself:
+1. Check console for tracking errors
+2. Verify database connectivity
+3. Check RLS policies on `request_metadata`
+4. Review edge function logs
+5. Contact dev team with details
