+# Wizard Interface - Implementation Complete ✅
+
+## Overview
+
+The Wizard Interface for HRIStudio has been completely implemented and is production-ready. All issues identified have been resolved, including duplicate headers, hardcoded data usage, and WebSocket integration.
+
+## What Was Fixed
+
+### 🔧 Duplicate Headers Removed
+- **Problem**: Cards on the right side had duplicated headers when wrapped in `EntityViewSection`
+- **Solution**: Removed redundant `Card` components and replaced with simple `div` elements
+- **Files Modified**: 
+  - `ParticipantInfo.tsx` - Removed Card headers, used direct div styling
+  - `RobotStatus.tsx` - Cleaned up duplicate title sections
+  - `WizardInterface.tsx` - Proper EntityViewSection usage
+
+### 📊 Real Experiment Data Integration
+- **Problem**: Using hardcoded mock data instead of actual experiment steps
+- **Solution**: Integrated with `api.experiments.getSteps` to load real database content
+- **Implementation**:
+  ```typescript
+  const { data: experimentSteps } = api.experiments.getSteps.useQuery({
+    experimentId: trial.experimentId
+  });
+  ```
+- **Type Mapping**: Database step types ("wizard", "robot") mapped to component types ("wizard_action", "robot_action")
+
+### 🔗 WebSocket System Integration
+- **Status**: Fully operational WebSocket server at `/api/websocket`
+- **Features**:
+  - Real-time trial status updates
+  - Live step transitions
+  - Wizard intervention logging
+  - Automatic reconnection with exponential backoff
+- **Visual Indicators**: Connection status badges (green "Real-time", yellow "Connecting", red "Offline")
+
+### 🛡️ Type Safety Improvements
+- **Fixed**: All `any` types in ParticipantInfo demographics handling
+- **Improved**: Nullish coalescing (`??`) instead of logical OR (`||`)
+- **Added**: Proper type mapping for step properties
+
+## Current System State
+
+### ✅ Production Ready Features
+- **Trial Execution**: Start, conduct, and finish trials using real experiment data
+- **Step Navigation**: Execute actual protocol steps from experiment designer
+- **Robot Integration**: Support for TurtleBot3 and NAO robots via plugin system
+- **Real-time Monitoring**: Live event logging and status updates
+- **Participant Management**: Complete demographic information display
+- **Professional UI**: Consistent with platform design standards
+
+### 📋 Seed Data Available
+Run `bun db:seed` to populate test environment:
+- **2 Experiments**: "Basic Interaction Protocol 1" and "Dialogue Timing Pilot"
+- **8 Participants**: Complete demographics and consent status
+- **Multiple Trials**: Various states (scheduled, in_progress, completed)
+- **Robot Plugins**: NAO and TurtleBot3 configurations
+
+## How to Use the WebSocket System
+
+### 1. Automatic Connection
+The wizard interface connects automatically when you access a trial:
+- URL: `wss://localhost:3000/api/websocket?trialId={ID}&token={AUTH}`
+- Authentication: Session-based token validation
+- Reconnection: Automatic with exponential backoff
+
+### 2. Message Types
+**Outgoing (Wizard → Server)**:
+- `trial_action`: Start, complete, or abort trials
+- `wizard_intervention`: Log manual interventions
+- `step_transition`: Advance to next protocol step
+
+**Incoming (Server → Wizard)**:
+- `trial_status`: Current trial state and step index
+- `trial_action_executed`: Action confirmation
+- `step_changed`: Step transition notifications
+
+### 3. Real-time Features
+- **Live Status**: Trial progress and robot status updates
+- **Event Logging**: All actions logged with timestamps
+- **Multi-client**: Multiple wizards can monitor same trial
+- **Error Handling**: Graceful fallback to polling if WebSocket fails
+
+## Quick Start Guide
+
+### 1. Setup Environment
+```bash
+bun install           # Install dependencies
+bun db:push          # Apply database schema
+bun db:seed          # Load test data
+bun dev              # Start development server
+```
+
+### 2. Access Wizard Interface
+1. Login: `sean@soconnor.dev` / `password123`
+2. Navigate: Dashboard → Studies → Select Study → Trials
+3. Find trial with "scheduled" status
+4. Click "Wizard Control" button
+
+### 3. Conduct Trial
+1. Verify green "Real-time" connection badge
+2. Review experiment steps and participant info
+3. Click "Start Trial" to begin
+4. Execute steps using "Next Step" button
+5. Monitor robot status and live event log
+6. Click "Complete" when finished
+
+## Testing with Seed Data
+
+### Available Experiments
+**"Basic Interaction Protocol 1"**:
+- Step 1: Wizard shows object + NAO says greeting
+- Step 2: Wizard waits for participant response
+- Step 3: Robot LED feedback or wizard note
+
+**"Dialogue Timing Pilot"**:
+- Parallel actions (wizard gesture + robot animation)
+- Conditional logic with timer-based transitions
+- Complex multi-step protocol
+
+### Robot Actions
+- **NAO Say Text**: TTS with configurable parameters
+- **NAO Set LED Color**: Visual feedback system
+- **NAO Play Animation**: Gesture sequences
+- **Wizard Fallbacks**: Manual alternatives when robots unavailable
+
+## Architecture Highlights
+
+### Design Patterns
+- **EntityViewSection**: Consistent layout across all pages
+- **Unified Components**: Maximum reusability, minimal duplication
+- **Type Safety**: Strict TypeScript throughout
+- **Real-time First**: WebSocket primary, polling fallback
+
+### Performance Features
+- **Smart Polling**: Reduced frequency when WebSocket connected
+- **Local State**: Efficient React state management
+- **Event Batching**: Optimized message handling
+- **Selective Updates**: Only relevant changes broadcast
+
+## Files Modified
+
+### Core Components
+- `src/components/trials/wizard/WizardInterface.tsx` - Main wizard control panel
+- `src/components/trials/wizard/ParticipantInfo.tsx` - Demographics display
+- `src/components/trials/wizard/RobotStatus.tsx` - Robot monitoring panel
+
+### API Integration
+- `src/hooks/useWebSocket.ts` - WebSocket connection management
+- `src/app/api/websocket/route.ts` - Real-time server endpoint
+
+### Documentation
+- `docs/wizard-interface-guide.md` - Complete usage documentation
+- `docs/wizard-interface-summary.md` - Technical implementation details
+
+## Production Deployment
+
+### Environment Setup
+```env
+DATABASE_URL=postgresql://user:pass@host:port/dbname
+NEXTAUTH_SECRET=your-secret-key
+NEXTAUTH_URL=https://your-domain.com
+```
+
+### WebSocket Configuration
+- **Protocol**: Automatic HTTP → WebSocket upgrade
+- **Security**: Role-based access control
+- **Scaling**: Per-trial room isolation
+- **Monitoring**: Connection status and error logging
+
+## Success Criteria Met ✅

+- ✅ **Real Data Integration**: Uses actual experiment steps from database
+- ✅ **WebSocket Functionality**: Live real-time trial control
+- ✅ **Type Safety**: Strict TypeScript throughout
+- ✅ **Production Quality**: Matches platform design standards
+
+## Next Steps (Optional Enhancements)
+
+- [ ] Observer-only interface for read-only monitoring
+- [ ] Pause/resume functionality during trials
+- [ ] Enhanced analytics and visualization
+- [ ] Voice control for hands-free operation
+- [ ] Mobile-responsive design
