fix: resolve all three functional issues in trial execution

- WebSocket broadcasts: Next.js tRPC router now routes broadcasts via
  POST /internal/broadcast on the Bun ws-server process, which holds
  the actual client connections. Broadcasts were previously silently
  dropped due to the split singleton across processes.

- ws-server stubs: request_trial_status and request_trial_events now
  use the real async DB methods instead of the stub getTrialStatusSync/
  getTrialEventsSync that always returned null/[].

- Duplicate branch case: removed the unreachable second case "branch"
  block in executeAction switch; server-side branching is a pass-through
  since routing is client-orchestrated.

-You are an expert in TypeScript, Clerk, Node.js, Drizzle ORM, Next.js App Router, React, Shadcn UI, Radix UI and Tailwind.
-
-Key Principles
-- Write concise, technical TypeScript code with accurate examples.
-- Use functional and declarative programming patterns; avoid classes.
-- Prefer iteration and modularization over code duplication.
-- Use descriptive variable names with auxiliary verbs (e.g., isLoading, hasError).
-- Structure files: exported component, subcomponents, helpers, static content, types.
-- When working with a database, use Drizzle ORM.
-- When working with authentication, use Clerk.
-
-Naming Conventions
-- Use lowercase with dashes for directories (e.g., components/auth-wizard).
-- Favor named exports for components.
-
-TypeScript Usage
-- Use TypeScript for all code; prefer interfaces over types.
-- Avoid enums; use maps instead.
-- Use functional components with TypeScript interfaces.
-
-Syntax and Formatting
-- Use the "function" keyword for pure functions.
-- Avoid unnecessary curly braces in conditionals; use concise syntax for simple statements.
-- Use declarative JSX.
-
-UI and Styling
-- Use Shadcn UI, Radix, and Tailwind for components and styling.
-- Implement responsive design with Tailwind CSS; use a mobile-first approach.
-
-Performance Optimization
-- Minimize 'use client', 'useEffect', and 'setState'; favor React Server Components (RSC).
-- Wrap client components in Suspense with fallback.
-- Use dynamic loading for non-critical components.
-- Optimize images: use WebP format, include size data, implement lazy loading.
-
-Key Conventions
-- Use 'nuqs' for URL search parameter state management.
-- Optimize Web Vitals (LCP, CLS, FID).
-- Limit 'use client':
-- Favor server components and Next.js SSR.
-- Use only for Web API access in small components.
-- Avoid for data fetching or state management.

+- **Commands**: Use `bun` exclusively for all operations
+
+## Code Patterns & Standards
+
+### Entity Forms (Unified Pattern)
+ALL entity creators/editors use the unified `EntityForm` component:
+```typescript
+// Standard form implementation pattern
+export function EntityForm({ mode, entityId }: EntityFormProps) {
+  const form = useForm<EntityFormData>({
+    resolver: zodResolver(entitySchema),
+    defaultValues: { /* ... */ }
+  });
+
+  return (
+    <EntityForm
+      mode={mode}
+      entityName="Entity"
+      form={form}
+      onSubmit={handleSubmit}
+      sidebar={<NextSteps />}
+    >
+      {/* Form fields */}
+    </EntityForm>
+  );
+}
+```
+
+### Data Tables (Unified Pattern)
+ALL entity lists use the unified `DataTable` component:
+```typescript
+<DataTable
+  columns={entityColumns}
+  data={entities}
+  searchKey="name"
+  onExport={handleExport}
+  showColumnToggle
+/>
+```
+
+### tRPC API Patterns
+```typescript
+// Router organization by domain
+export const entityRouter = createTRPCRouter({
+  getAll: protectedProcedure
+    .input(z.object({ search: z.string().optional() }))
+    .query(async ({ ctx, input }) => { /* ... */ }),
+
+  create: protectedProcedure
+    .input(createEntitySchema)
+    .mutation(async ({ ctx, input }) => { /* ... */ }),
+});
+```
+
+### Authentication & Authorization
+```typescript
+// Role-based procedure protection
+export const adminProcedure = protectedProcedure.use(({ ctx, next }) => {
+  if (ctx.session.user.role !== "administrator") {
+    throw new TRPCError({ code: "FORBIDDEN" });
+  }
+  return next();
+});
+```
+
+## Key Implementation Rules
+
+### Required Patterns
+- Use unified `EntityForm` for ALL entity creators/editors (Studies, Experiments, Participants, Trials)
+- Use unified `DataTable` for ALL entity lists with consistent column patterns
+- All entity operations are full pages, NEVER modals or dialogs
+- Follow the established file naming: PascalCase for components, camelCase for utilities
+- Use Server Components by default, minimize 'use client' directives
+- Implement proper loading states and error boundaries for all async operations
+- NEVER use emojis - use Lucide icons exclusively for all visual elements
+- Maximize component reusability - create shared patterns and abstractions
+- ALL entity view pages must follow consistent patterns and layouts
+
+### TypeScript Standards
+- 100% type safety - NO `any` types allowed in production code
+- Use Zod schemas for input validation, infer types from schemas
+- Define explicit return types for all functions
+- Use const assertions for literal types: `const roles = ["admin", "user"] as const`
+- Prefer interfaces over types for component props
+
+### Database Operations
+- Use Drizzle ORM exclusively with type-safe queries
+- Implement soft deletes with `deleted_at` timestamps
+- Add `created_at` and `updated_at` to all tables
+- Use transactions for multi-table operations
+- Create indexes for foreign keys and frequently queried fields
+
+### Security & Performance
+- Validate ALL inputs on both client and server with Zod
+- Implement role-based authorization at route and resource level
+- Use optimistic updates for better UX with proper error handling
+- Minimize database queries with efficient joins and proper indexing
+- Follow WCAG 2.1 AA accessibility standards throughout
+
+## UI/UX Standards
+- **Icons**: Use Lucide icons exclusively - NO emojis in codebase or responses
+- **Reusability**: Maximize component reuse through shared patterns and abstractions
+- **Entity Views**: All entity view pages (studies, experiments, participants, trials) must follow consistent patterns
+- **Page Structure**: Use global page headers, breadcrumbs, and consistent layout patterns
+- **Visual Consistency**: Maintain consistent spacing, typography, and interaction patterns
+
+## Development Commands
+- `bun install` - Install dependencies
+- `bun dev` - Start development server (ONLY when actively developing)
+- `bun build` - Build for production
+- `bun typecheck` - Run TypeScript validation
+- `bun lint` - Run ESLint with autofix
+- `bun db:push` - Push schema changes (use instead of migrations in dev)
+- `bun db:seed` - Populate database with realistic test data
+
+## Development Restrictions
+- NEVER run `bun dev` or development servers during implementation assistance
+- NEVER run `bun db:studio` during development sessions
+- Use ONLY `bun typecheck`, `bun build`, `bun lint` for verification
+- Use `bun db:push` for schema changes, not migrations in development
+
+## Current Status
+- **Current Work**: Experiment designer enhancement with advanced visual programming
+- **Next Phase**: Enhanced step configuration modals and workflow validation
+- **Deployment**: Configured for Vercel with Cloudflare R2 and PostgreSQL
+
+## Robot Integration
+- Plugin-based architecture supporting RESTful APIs, ROS2 (via rosbridge), and custom protocols
+- WebSocket communication for real-time robot control during trials
+- Type-safe action definitions with parameter schemas and validation
+- See `docs/ros2-integration.md` for complete integration guide
+
+Follow Next.js 15 best practices for Data Fetching, Rendering, and Routing. Always reference the comprehensive documentation in the `docs/` folder before implementing new features.
+
+## Documentation Guidelines
+- **Location**: ALL documentation must be in `docs/` folder - NEVER create markdown files in root
+- **Structure**: Use existing documentation organization and file naming conventions
+- **Cross-References**: Always link to related documentation files using relative paths
+- **Updates**: When adding features, update relevant docs files (don't create new ones unless necessary)
+- **Completeness**: Document all new features, APIs, components, and architectural changes
+- **Format**: Use consistent markdown formatting with proper headers, code blocks, and lists
+- **Status Tracking**: Update `docs/work_in_progress.md` for active development
+- **Integration**: Ensure new docs integrate with existing quick-reference and overview files
+
+## Plugin System Documentation Standards
+- **Core Blocks**: Document in `docs/core-blocks-system.md` (to be created)
+- **Robot Plugins**: Use existing `docs/plugin-system-implementation-guide.md`
+- **Repository Structure**: Document all plugin repositories in dedicated sections
+- **Block Definitions**: Include JSON schema examples and validation rules
+- **Loading Process**: Document async loading, error handling, and fallback systems
+
+## Response Guidelines
+- Keep responses concise and minimal
+- No emojis or excessive formatting
+- Focus on essential information only
+- Prioritize code fixes over explanations
+- Use bullet points for lists, not checkmarks
+- Respond with requested format (edits, diagnostics, etc.)
+- Avoid verbose summaries unless explicitly requested

+# NAO6 Integration Handoff Document
+
+**Date**: 2024-11-12  
+**Status**: ✅ Production Ready - Action Execution Pending  
+**Session Duration**: ~3 hours  
+
+---
+
+## 🎯 What's Ready
+
+### ✅ Completed
+1. **Live Robot Connection** - NAO6 @ nao.local fully connected via ROS2
+2. **Plugin System** - NAO6 ROS2 Integration plugin (v2.1.0) with 10 actions
+3. **Database Integration** - Plugin installed, experiments seeded with NAO6 actions
+4. **Web Test Interface** - `/nao-test` page working with live robot control
+5. **Documentation** - 1,877 lines of comprehensive technical docs
+6. **Repository Cleanup** - Consolidated into `robot-plugins` git repo (pushed to GitHub)
+
+### 🚧 Next Step: Action Execution
+**Current Gap**: Experiment designer → WebSocket → ROS2 → NAO flow not implemented
+
+The plugin is loaded, actions are in the database, but clicking "Execute" in the wizard interface doesn't send commands to the robot yet.
+
+---
+
+## 🚀 Quick Start (For Next Agent)
+
+### Terminal 1: Start NAO6 Integration
+```bash
+cd ~/Documents/Projects/nao6-hristudio-integration
+./start-nao6.sh
+```
+**Expect**: Color-coded logs showing NAO Driver, ROS Bridge, ROS API running
+
+### Terminal 2: Start HRIStudio
+```bash
+cd ~/Documents/Projects/hristudio
+bun dev
+```
+**Access**: http://localhost:3000
+
+### Verify Setup
+1. **Test Page**: http://localhost:3000/nao-test
+   - Click "Connect" → Should turn green
+   - Click "Speak" → NAO should talk
+   - Movement buttons → NAO should move
+
+2. **Experiment Designer**: http://localhost:3000/experiments/[id]/designer
+   - Check "Basic Interaction Protocol 1"
+   - Should see NAO6 actions in action library
+   - Drag actions to experiment canvas
+
+3. **Database Check**:
+   ```bash
+   bun db:seed  # Should complete without errors
+   ```

+
+## 🔧 Current System State
+
+### Database
+- **2 repositories**: Core + Robot Plugins
+- **4 plugins**: Core System, TurtleBot3 Burger, TurtleBot3 Waffle, **NAO6 ROS2 Integration**
+- **NAO6 installed in**: "Basic Interaction Protocol 1" study
+- **Experiment actions**: Step 1 has "NAO Speak Text", Step 3 has "NAO Move Head"
+
+### ROS2 System
+- **26 topics** available when `start-nao6.sh` is running
+- **Key topics**: `/speech`, `/cmd_vel`, `/joint_angles`, `/joint_states`, `/bumper`, etc.
+- **WebSocket**: ws://localhost:9090 (rosbridge_websocket)
+
+### Robot
+- **IP**: nao.local (134.82.159.168)
+- **Credentials**: nao / robolab
+- **Status**: Awake and responsive (test with ping)
+
+---
+
+## 🎯 Implementation Needed
+
+### 1. Action Execution Flow
+**Where to implement**: 
+- `src/components/trials/WizardInterface.tsx` or similar
+- Connect "Execute Action" button → WebSocket → ROS2
+
+**What it should do**:
+```typescript
+// When wizard clicks "Execute Action" on a NAO6 action
+function executeNAO6Action(action: Action) {
+  // 1. Get action parameters from database
+  const { type, parameters } = action;
+  
+  // 2. Connect to WebSocket (if not connected)
+  const ws = new WebSocket('ws://localhost:9090');
+  
+  // 3. Map action type to ROS2 topic
+  const topicMapping = {
+    'nao6_speak': '/speech',
+    'nao6_move_forward': '/cmd_vel',
+    'nao6_move_head': '/joint_angles',
+    // ... etc
+  };
+  
+  // 4. Create ROS message
+  const rosMessage = {
+    op: 'publish',
+    topic: topicMapping[type],
+    msg: formatMessageForROS(type, parameters)
+  };
+  
+  // 5. Send to robot
+  ws.send(JSON.stringify(rosMessage));
+  
+  // 6. Log to trial_events
+  logTrialEvent({
+    trial_id: currentTrialId,
+    event_type: 'action_executed',
+    event_data: { action, timestamp: Date.now() }
+  });
+}
+```
+
+### 2. Message Formatting
+**Reference**: See `nao6-hristudio-integration/docs/HRISTUDIO-ACTION-MAPPING.md`
+
+**Examples**:
+```typescript
+function formatMessageForROS(actionType: string, params: any) {
+  switch(actionType) {
+    case 'nao6_speak':
+      return { data: params.text };
+      
+    case 'nao6_move_forward':
+      return {
+        linear: { x: params.speed, y: 0, z: 0 },
+        angular: { x: 0, y: 0, z: 0 }
+      };
+      
+    case 'nao6_move_head':
+      return {
+        joint_names: ['HeadYaw', 'HeadPitch'],
+        joint_angles: [params.yaw, params.pitch],
+        speed: params.speed,
+        relative: 0
+      };
+  }
+}
+```
+
+### 3. WebSocket Connection Management
+**Suggested approach**:
+- Create `useROSBridge()` hook in `src/hooks/`
+- Manage connection state, auto-reconnect
+- Provide `publish()`, `subscribe()`, `callService()` methods
+
+---
+
+## 🧪 Testing Checklist
+
+Before marking as complete:
+- [ ] Can execute "Speak Text" action from wizard interface → NAO speaks
+- [ ] Can execute "Move Forward" action → NAO walks
+- [ ] Can execute "Move Head" action → NAO moves head
+- [ ] Actions are logged to `trial_events` table
+- [ ] Connection errors are handled gracefully
+- [ ] Emergency stop works from wizard interface
+- [ ] Multiple actions in sequence work
+- [ ] Sensor monitoring displays in wizard interface
+

+
+## 📚 Reference Documentation
+
+### Primary Sources
+1. **Working Example**: `src/app/(dashboard)/nao-test/page.tsx`
+   - Lines 67-100: WebSocket connection setup
+   - Lines 200-350: Action execution examples
+   - This is WORKING code - use it as template!
+
+2. **Action Specifications**: `nao6-hristudio-integration/docs/HRISTUDIO-ACTION-MAPPING.md`
+   - Lines 1-100: Each action with parameters
+   - TypeScript types already defined
+   - WebSocket message formats included
+
+3. **ROS2 Topics**: `nao6-hristudio-integration/docs/NAO6-ROS2-TOPICS.md`
+   - Complete message type definitions
+   - Examples for each topic
+
+### TypeScript Types
+Already defined in action mapping doc:
+```typescript
+interface SpeakTextAction {
+  action: 'nao6_speak';
+  parameters: {
+    text: string;
+    volume?: number;
+  };
+}
+
+interface MoveForwardAction {
+  action: 'nao6_move_forward';
+  parameters: {
+    speed: number;
+    duration: number;
+  };
+}
+```
+
+---
+
+## 🔍 Where to Look
+
+### To understand plugin loading:
+- `src/components/experiments/designer/ActionRegistry.ts`
+- `src/components/experiments/designer/panels/ActionLibraryPanel.tsx`
+
+### To see working WebSocket code:
+- `src/app/(dashboard)/nao-test/page.tsx` (fully functional!)
+
+### To find action execution trigger:
+- Search for: `executeAction`, `onActionExecute`, `runAction`
+- Likely in: `src/components/trials/` or `src/components/experiments/`
+
+---
+
+## 🚨 Important Notes
+
+### DO NOT
+- ❌ Modify `robot-plugins/` without committing/pushing (it's a git repo)
+- ❌ Change plugin structure without updating seed script
+- ❌ Remove `start-nao6.sh` - it's the main entry point
+- ❌ Hard-code WebSocket URLs - use config/env vars
+
+### DO
+- ✅ Use existing `/nao-test` page code as reference
+- ✅ Test with live robot frequently
+- ✅ Log all actions to `trial_events` table
+- ✅ Handle connection errors gracefully
+- ✅ Add loading states for action execution
+
+### Known Working
+- ✅ WebSocket connection (`/nao-test` proves it works)
+- ✅ ROS2 topics (26 topics verified)
+- ✅ Plugin loading (shows in action library)
+- ✅ Database integration (seed script works)
+
+### Known NOT Working
+- ❌ Action execution from experiment designer/wizard interface
+- ❌ Sensor data display in wizard interface (topics exist, just not displayed)
+- ❌ Camera streaming to browser
+
+---
+
+## 🤝 Session Handoff Summary
+
+### What We Did
+1. Connected to live NAO6 robot at nao.local
+2. Documented all 26 ROS2 topics with complete specifications
+3. Created clean plugin with 10 actions
+4. Integrated plugin into HRIStudio database
+5. Built working test interface proving WebSocket → ROS2 → NAO works
+6. Cleaned up repositories (removed duplicates, committed to git)
+7. Updated experiments to use NAO6 actions
+8. Fixed APT repository issues
+9. Created comprehensive documentation (1,877 lines)
+
+### What's Left
+**ONE THING**: Connect the experiment designer's "Execute Action" button to the WebSocket/ROS2 system.
+
+The hard part is done. The `/nao-test` page is a fully working example of exactly what you need to do - just integrate that pattern into the wizard interface.
+
+---
+
+## 🎓 Key Insights
+
+1. **We're NOT writing a WebSocket server** - using ROS2's official `rosbridge_websocket`
+2. **The test page works perfectly** - copy its pattern
+3. **All topics are documented** - no guesswork needed
+4. **Plugin is in database** - just needs execution hookup
+5. **Robot is live and responsive** - test frequently!
+
+---
+
+## ⚡ Quick Commands
+
+```bash
+# Start everything
+cd ~/Documents/Projects/nao6-hristudio-integration && ./start-nao6.sh
+cd ~/Documents/Projects/hristudio && bun dev
+
+# Test robot
+curl -X POST http://localhost:9090 -d '{"op":"publish","topic":"/speech","msg":{"data":"Test"}}'
+
+# Reset robot
+sshpass -p robolab ssh nao@nao.local \
+  "python2 -c 'import sys; sys.path.append(\"/opt/aldebaran/lib/python2.7/site-packages\"); import naoqi; p=naoqi.ALProxy(\"ALRobotPosture\",\"127.0.0.1\",9559); p.goToPosture(\"StandInit\", 0.5)'"
+
+# Reseed database
+cd ~/Documents/Projects/hristudio && bun db:seed
+```
+
+---
+
+**Next Agent**: Start by reviewing `/nao-test/page.tsx` - it's the Rosetta Stone for this integration. Everything you need is already working there!
+
+**Estimated Time**: 2-4 hours to implement action execution  
+**Difficulty**: Medium (pattern exists, just needs integration)  
+**Priority**: High (this is the final piece)
+
+---
+
+**Status**: 🟢 Ready for implementation  
+**Blocker**: None - all prerequisites met  
+**Dependencies**: Robot must be running (`start-nao6.sh`)

+# Trial Start Debug Guide
+
+## ❌ **Problem**: "I can't start the trial"
+
+This guide will help you systematically debug why the trial start functionality isn't working.
+
+---
+
+## 🔍 **Step 1: Verify System Setup**
+
+### Database Connection
+```bash
+# Check if database is running
+docker ps | grep postgres
+
+# If not running, start it
+bun run docker:up
+
+# Check database schema is up to date
+bun db:push
+
+# Verify seed data exists
+bun db:seed
+```
+
+### Build Status
+```bash
+# Ensure project builds without errors
+bun run build
+
+# Should complete successfully with no TypeScript errors
+```
+
+---
+
+## 🔍 **Step 2: Browser-Based Testing**
+
+### Access the Wizard Interface
+1. Start dev server: `bun dev`
+2. Open browser: `http://localhost:3000`
+3. Login: `sean@soconnor.dev` / `password123`
+4. Navigate: Studies → [First Study] → Trials → [First Trial] → Wizard Interface
+
+### Check Browser Console
+Open Developer Tools (F12) and look for:
+
+**Expected Debug Messages** (when clicking "Start Trial"):
+```
+[WizardInterface] Starting trial: <id> Current status: scheduled
+[WizardControlPanel] Start Trial clicked
+```
+
+**Error Messages to Look For**:
+- Network errors (red entries in Console)
+- tRPC errors (search for "trpc" or "TRPC")
+- Authentication errors (401/403 status codes)
+- Database errors (check Network tab)
+
+---
+
+## 🔍 **Step 3: Test Database Access**
+
+### Quick API Test
+Visit this URL in your browser while dev server is running:
+```
+http://localhost:3000/api/test-trial
+```
+
+**Expected Response**:
+```json
+{
+  "success": true,
+  "message": "Database connection working",
+  "trials": [...],
+  "count": 4
+}
+```
+
+**If you get an error**, the database connection is broken.
+
+### Check Specific Trial
+If the above works, test with a specific trial ID:
+```
+http://localhost:3000/api/test-trial?id=<trial-id-from-above-response>
+```
+
+---
+
+## 🔍 **Step 4: Verify Trial Status**
+
+### Requirements for Starting Trial
+1. **Trial must exist** - Check API response has trials
+2. **Trial must be "scheduled"** - Status should be "scheduled", not "in_progress" or "completed"  
+3. **User must have permissions** - Must be administrator, researcher, or wizard role
+4. **Experiment must have steps** - Trial needs an experiment with defined steps
+
+### Check Trial Data
+In browser console, after navigating to wizard interface:
+```javascript
+// Check trial data
+console.log("Current trial:", window.location.pathname);
+
+// Check user session
+fetch('/api/auth/session').then(r => r.json()).then(console.log);
+```
+
+---
+
+## 🔍 **Step 5: tRPC API Testing**
+
+### Test tRPC Endpoint Directly
+In browser console on the wizard page:
+```javascript
+// This should work if you're on the wizard interface page
+// Replace 'TRIAL_ID' with actual trial ID from URL
+fetch('/api/trpc/trials.get?batch=1&input={"0":{"json":{"id":"TRIAL_ID"}}}')
+  .then(r => r.json())
+  .then(console.log);
+```
+
+### Test Start Trial Endpoint
+```javascript
+// Test the start trial mutation
+fetch('/api/trpc/trials.start', {
+  method: 'POST',
+  headers: { 'Content-Type': 'application/json' },
+  body: JSON.stringify({
+    "0": {
+      "json": {
+        "id": "TRIAL_ID_HERE"
+      }
+    }
+  })
+}).then(r => r.json()).then(console.log);
+```
+
+---
+
+## 🔍 **Step 6: Common Issues & Fixes**
+
+### Issue: "Start Trial" Button Doesn't Respond
+- Check browser console for JavaScript errors
+- Verify the button isn't disabled
+- Check if `isStarting` state is stuck on `true`
+
+### Issue: Network Error / API Not Found
+- Check middleware isn't blocking tRPC routes
+- Verify NextAuth session is valid
+- Check if API routes are properly built
+
+### Issue: Permission Denied
+- Check user role: must be administrator, researcher, or wizard
+- Verify study membership if role-based access is enabled
+- Check `checkTrialAccess` function in trials router
+
+### Issue: "Trial can only be started from scheduled status"
+- Current trial status is not "scheduled"
+- Find a trial with "scheduled" status or create one manually
+- Check seed data created scheduled trials properly
+
+### Issue: Database Connection Error
+- Database container not running
+- Environment variables missing/incorrect
+- Schema not pushed or out of date
+
+---
+
+## 🔧 **Manual Debugging Steps**
+
+### Create Test Trial
+If no scheduled trials exist:
+```sql
+-- Connect to database and create a test trial
+INSERT INTO trial (
+  id, 
+  experiment_id, 
+  participant_id, 
+  status, 
+  session_number,
+  scheduled_at,
+  created_at,
+  updated_at
+) VALUES (
+  gen_random_uuid(),
+  'EXPERIMENT_ID_HERE',
+  'PARTICIPANT_ID_HERE', 
+  'scheduled',
+  1,
+  NOW(),
+  NOW(),
+  NOW()
+);
+```
+
+### Check User Permissions
+```sql
+-- Check user system roles
+SELECT u.email, usr.role 
+FROM users u 
+LEFT JOIN user_system_roles usr ON u.id = usr.user_id 
+WHERE u.email = 'sean@soconnor.dev';
+
+-- Check study memberships
+SELECT u.email, sm.role, s.name as study_name
+FROM users u 
+LEFT JOIN study_members sm ON u.id = sm.user_id
+LEFT JOIN studies s ON sm.study_id = s.id
+WHERE u.email = 'sean@soconnor.dev';
+```
+
+---
+
+## 🚨 **Emergency Fixes**
+
+### Quick Reset
+```bash
+# Complete reset of database and seed data
+bun run docker:down
+bun run docker:up
+bun db:push
+bun db:seed
+```
+
+### Bypass Authentication (Development Only)
+In `src/server/api/routers/trials.ts`, temporarily comment out the permission check:
+```typescript
+// await checkTrialAccess(db, userId, input.id, [
+//   "owner",
+//   "researcher", 
+//   "wizard",
+// ]);
+```
+
+---
+
+## 📞 **Getting Help**
+

+# 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

+
+## Key Features
+
+- **Hierarchical Structure**: Study → Experiment → Trial → Step → Action
+- **Visual Designer**: 26+ core blocks (events, wizard actions, control flow, observation)
+- **Conditional Branching**: Wizard choices with convergence paths
+- **WebSocket Real-time**: Trial updates with auto-reconnect
+- **Plugin System**: Robot-agnostic via identifier lookup
+- **Docker NAO6**: Three-service ROS2 integration
+- **Forms System**: Consent forms, surveys, questionnaires with templates
+- **Role-based Access**: Owner, Researcher, Wizard, Observer permissions
+
+## System Components
+
+### Backend (src/server/)
+- `api/routers/` - 13 tRPC routers (studies, experiments, trials, participants, forms, etc.)
+- `db/schema.ts` - Drizzle schema (33 tables)
+- `services/trial-execution.ts` - Trial execution engine
+- `services/websocket-manager.ts` - Real-time connections
+
+### Frontend (src/)
+- `app/` - Next.js App Router pages
+- `components/trials/wizard/` - Wizard interface
+- `components/trials/forms/` - Form builder and viewer
+- `hooks/useWebSocket.ts` - Real-time trial updates
+- `lib/ros/wizard-ros-service.ts` - Robot control
+
+## Plugin Identifier System
+
+```typescript
+// Plugins table has:
+// - identifier: "nao6-ros2" (unique, machine-readable)
+// - name: "NAO6 Robot (ROS2 Integration)" (display)
+
+// Lookup order in trial execution:
+1. Look up by identifier (e.g., "nao6-ros2")
+2. Fall back to name (e.g., "NAO6 Robot")
+3. Return null if not found
+```
+
+## Branching Flow
+
+```
+Step 3 (Comprehension Check)
+  └── wizard_wait_for_response
+      ├── "Correct" → nextStepId = step4a.id
+      └── "Incorrect" → nextStepId = step4b.id
+
+Step 4a/4b (Branch A/B)
+  └── conditions.nextStepId: step5.id → converge
+
+Step 5 (Story Continues)
+  └── Linear progression to conclusion
+```
+
+## Development Workflow
+
+```bash
+# Make changes
+# ...
+
+# Validate
+bun typecheck
+bun lint
+
+# Push schema (if changed)
+bun db:push
+
+# Reseed (if data changed)
+bun db:seed
+```
+
+## Common Issues
+
+| Issue | Solution |
+|-------|----------|
+| Build errors | `rm -rf .next && bun build` |
+| DB issues | `bun db:push --force && bun db:seed` |
+| Type errors | Check `bun typecheck` output |
+| WebSocket fails | Verify port 3001 available |

+# HRIStudio - March 2026 Development Summary
+
+## What We Did This Session
+
+### 1. Docker Integration for NAO6 Robot
+**Files**: `nao6-hristudio-integration/`
+
+- Created `Dockerfile` with ROS2 Humble + naoqi packages
+- Created `docker-compose.yaml` with 3 services: `nao_driver`, `ros_bridge`, `ros_api`
+- Created `scripts/init_robot.sh` - Bash script to wake up robot via SSH when Docker starts
+- Fixed autonomous life disable issue (previously used Python `naoqi` package which isn't on PyPI)
+
+**Key insight**: Robot init via SSH + `qicli` calls instead of Python SDK
+
+### 2. Plugin System Fixes
+**Files**: `robot-plugins/plugins/nao6-ros2.json`, `src/lib/ros/wizard-ros-service.ts`
+
+- **Topic fixes**: Removed `/naoqi_driver/` prefix from topics (driver already provides unprefixed topics)
+- **say_with_emotion**: Fixed with proper NAOqi markup (`\rspd=120\^start(animations/...)`)
+- **wave_goodbye**: Added animated speech with waving gesture
+- **play_animation**: Added for predefined NAO animations
+- **Sensor topics**: Fixed camera, IMU, bumper, sonar, touch topics (removed prefix)
+
+### 3. Database Schema - Plugin Identifier
+**Files**: `src/server/db/schema.ts`, `src/server/services/trial-execution.ts`
+
+- Added `identifier` column to `plugins` table (unique, machine-readable ID like `nao6-ros2`)
+- `name` now for display only ("NAO6 Robot (ROS2 Integration)")
+- Updated trial-execution to look up by `identifier` first, then `name` (backwards compat)
+- Created migration script: `scripts/migrate-add-identifier.ts`
+
+### 4. Seed Script Improvements
+**Files**: `scripts/seed-dev.ts`
+
+- Fixed to use local plugin file (not remote `repo.hristudio.com`)
+- Added `identifier` field for all plugins (nao6, hristudio-core, hristudio-woz)
+- Experiment structure:
+  - Step 1: The Hook
+  - Step 2: The Narrative
+  - Step 3: Comprehension Check (conditional with wizard choices)
+  - Step 4a/4b: Branch A/B (with `nextStepId` conditions to converge)
+  - Step 5: Story Continues (convergence point)
+  - Step 6: Conclusion
+
+### 5. Robot Action Timing Fix
+**Files**: `src/lib/ros/wizard-ros-service.ts`
+
+- Speech actions now estimate duration: `1500ms emotion overhead + word_count * 300ms`
+- Added `say_with_emotion` and `wave_goodbye` as explicit built-in actions
+- Fixed 100ms timeout that was completing actions before robot finished
+
+### 6. Branching Logic Fixes (Critical!)
+**Files**: `src/components/trials/wizard/`
+
+**Bug 1**: `onClick={onNextStep}` passed event object instead of calling function
+- Fixed: `onClick={() => onNextStep()}`
+
+**Bug 2**: `onCompleted()` called after branch choice incremented action count
+- Fixed: Removed `onCompleted()` call after branch selection
+
+**Bug 3**: Branch A/B had no `nextStepId` condition, fell through to linear progression
+- Fixed: Added `conditions.nextStepId: step5.id` to Branch A and B
+
+**Bug 4**: Robot actions from previous step executed on new step (branching jumped but actions from prior step still triggered)
+- Root cause: `completedActionsCount` not being reset properly
+- Fixed: `handleNextStep()` now resets `completedActionsCount(0)` on explicit jump
+
+### 7. Auth.js to Better Auth Migration (Attempted, Reverted)
+**Status**: Incomplete - 41+ type errors remain
+
+The migration requires significant changes to how `session.user.roles` is accessed since Better Auth doesn't include roles in session by default. Would need to fetch roles from database on each request.
+
+**Recommendation**: Defer until more development time available.
+
+---
+
+## Current Architecture
+
+### Plugin Identifier System
+```
+plugins table:
+  - id: UUID (primary key)
+  - identifier: varchar (unique, e.g. "nao6-ros2")
+  - name: varchar (display, e.g. "NAO6 Robot (ROS2 Integration)")
+  - robotId: UUID (optional FK to robots)
+  - actionDefinitions: JSONB
+
+actions table:
+  - type: "plugin.action" (e.g., "nao6-ros2.say_with_emotion")
+  - pluginId: varchar (references plugins.identifier)
+```
+
+### Branching Flow
+```
+Step 3 (Comprehension Check)
+  └── wizard_wait_for_response action
+      ├── Click "Correct" → setLastResponse("Correct") → nextStepId=step4a.id
+      └── Click "Incorrect" → setLastResponse("Incorrect") → nextStepId=step4b.id
+
+Step 4a/4b (Branches)
+  └── conditions.nextStepId: step5.id → jump to Story Continues
+
+Step 5 (Story Continues)
+  └── Linear progression to Step 6
+
+Step 6 (Conclusion)
+  └── Trial complete
+```
+
+### ROS Topics (NAO6)
+```
+/speech          - Text-to-speech
+/cmd_vel         - Velocity commands
+/joint_angles    - Joint position commands
+/camera/front/image_raw
+/camera/bottom/image_raw
+/imu/torso
+/bumper
+/{hand,head}_touch
+/sonar/{left,right}
+/info
+```
+
+---
+
+## Known Issues / Remaining Work
+
+1. **Auth.js to Better Auth Migration** - Deferred, requires significant refactoring
+2. **robots.executeSystemAction** - Procedure not found error (fallback works but should investigate)
+3. **say_with_emotion via WebSocket** - May need proper plugin config to avoid fallback
+
+---
+
+## Docker Deployment
+
+```bash
+cd nao6-hristudio-integration
+docker compose up -d
+```
+
+Robot init runs automatically on startup (via `init_robot.sh`).
+
+---
+

+
+### Core Interface
+- **Three-panel layout**: Block Library | Experiment Flow | Properties
+- **Dense, structured design** replacing freeform canvas approach
+- **Resizable panels** with proper responsive behavior
+- **Dashboard integration** with existing breadcrumb system
+
+### Block System
+- **Six block categories** with distinct visual design:
+  - Events (Green/Play) - Trial triggers
+  - Wizard (Purple/Users) - Human actions  
+  - Robot (Blue/Bot) - Automated actions
+  - Control (Orange/GitBranch) - Flow control
+  - Sensors (Green/Activity) - Data collection
+- **Shape-based functionality**:
+  - Action blocks: Standard rounded rectangles
+  - Control blocks: C-shaped with nesting areas
+  - Hat blocks: Event triggers with distinctive tops
+- **Parameter system** with type-safe inputs and live preview
+
+### Advanced Features

+- **Block nesting** for control structures (repeat, if statements)
+- **Visual hierarchy** with indentation and connecting lines
+- **Real-time parameter editing** in dedicated properties panel
+- **Block removal** from nested structures
+- **Parameter preview** in block library drawer
+
+### Database Integration
+- **Enhanced schema** with new JSONB columns:
+  - `visual_design`: Complete block layout and parameters
+  - `execution_graph`: Compiled execution sequence  
+  - `plugin_dependencies`: Required robot platform plugins
+- **GIN indexes** on JSONB for fast query performance
+- **Plugin registry** tables for extensible block types
+
+## 🏗️ Technical Architecture
+
+### Core Components
+
+1. **EnhancedBlockDesigner** - Main container component
+2. **BlockPalette** - Left panel with draggable block categories
+3. **SortableBlock** - Individual block component with drag/sort capabilities
+4. **DroppableContainer** - Drop zones for control structures
+5. **DraggablePaletteBlock** - Draggable blocks in the palette
+
+### Block Registry System
+
+```typescript
+class BlockRegistry {
+  private blocks = new Map<string, PluginBlockDefinition>();
+  
+  // Core blocks: Events, Wizard Actions, Robot Actions, Control Flow, Sensors
+  // Extensible plugin architecture for additional robot platforms
+}
+```
+
+### Data Flow
+
+```
+1. Palette Block Drag → 2. Canvas Drop → 3. Block Creation → 4. State Update → 5. Database Save
+     ↓                      ↓                ↓                  ↓                 ↓
+ DraggablePaletteBlock → DroppableContainer → BlockRegistry → React State → tRPC API
+```
+
+## 🎨 Block Categories & Types
+
+### Events (Green - Play Icon)
+- **when trial starts** - Hat-shaped trigger block
+
+### Wizard Actions (Purple - Users Icon)  
+- **say** - Wizard speaks to participant
+- **gesture** - Wizard performs physical gesture
+
+### Robot Actions (Blue - Bot Icon)
+- **say** - Robot speaks using TTS
+- **move** - Robot moves in direction/distance
+- **look at** - Robot orients gaze to target
+
+### Control Flow (Orange - GitBranch Icon)
+- **wait** - Pause execution for time
+- **repeat** - Loop container with nesting
+- **if** - Conditional container with nesting
+
+### Sensors (Green - Activity Icon)
+- **observe** - Record behavioral observations
+
+## Technical Implementation
+
+### Drag & Drop System
+- **Library**: @dnd-kit/core with sortable and utilities
+- **Collision Detection**: closestCenter for optimal drop targeting
+- **Sensors**: Pointer (mouse/touch) + Keyboard for accessibility
+- **Drop Zones**: Main canvas, control block interiors, reordering
+
+### State Management
+```typescript
+interface BlockDesign {
+  id: string;
+  name: string;
+  description: string;
+  blocks: ExperimentBlock[];
+  version: number;
+  lastSaved: Date;
+}
+```
+
+### Database Schema
+```sql
+-- experiments table
+visualDesign JSONB,           -- Complete block design
+executionGraph JSONB,         -- Compiled execution plan  
+pluginDependencies TEXT[],    -- Required robot plugins
+
+-- GIN index for fast JSONB queries
+CREATE INDEX experiment_visual_design_idx ON experiments USING GIN (visual_design);
+```
+
+### API Integration
+```typescript
+// tRPC route: experiments.update
+updateExperiment.mutate({
+  id: experimentId,
+  visualDesign: {
+    blocks: design.blocks,
+    version: design.version,
+    lastSaved: new Date().toISOString(),
+  }
+});
+```
+
+### Architecture Decisions
+1. **Abandoned freeform canvas** in favor of structured vertical list
+2. **Used dnd-kit instead of native drag/drop** for reliability
+3. **Integrated with existing dashboard patterns** rather than custom UI
+4. **JSONB storage** for flexible schema evolution
+5. **Plugin-based block registry** for robot platform extensibility
+
+### Key Components
+- `EnhancedBlockDesigner.tsx` - Main interface (1,200+ lines)
+- `BlockRegistry` class - Manages available block types
+- Database schema extensions for visual design storage
+- Breadcrumb integration with existing dashboard system
+
+### Performance Optimizations
+- **Efficient rendering** with minimal re-renders
+- **Direct DOM manipulation** during drag operations
+- **Lazy loading** of block libraries
+- **Optimized state management** with React hooks
+
+## Challenges Solved
+
+### 1. Layout Conflicts
+- **Problem**: Full-screen designer conflicting with dashboard layout
+- **Solution**: Integrated within dashboard container with proper height management
+
+### 2. Drag and Drop Reliability
+- **Problem**: Native HTML drag/drop was buggy and inconsistent
+- **Solution**: Switched to dnd-kit for cross-platform reliability
+
+### 3. Control Flow Nesting
+- **Problem**: Complex logic for nested block structures
+- **Solution**: Droppable containers with visual feedback and proper data management
+
+### 4. Breadcrumb Integration
+- **Problem**: Custom breadcrumb conflicting with dashboard system
+- **Solution**: Used existing `useBreadcrumbsEffect` hook for proper integration
+
+### 5. Parameter Management
+- **Problem**: Complex parameter editing workflows
+- **Solution**: Dedicated properties panel with type-safe form controls
+
+## Code Quality Improvements
+
+### Removed Deprecated Files
+- `BlockDesigner.tsx` - Old implementation
+- `ExperimentDesigner.tsx` - Card-based approach
+- `ExperimentDesignerClient.tsx` - Wrapper component
+- `FlowDesigner.tsx` - React Flow attempt
+- `FreeFormDesigner.tsx` - Canvas approach
+- `flow-theme.css` - React Flow styling
+
+### Documentation Cleanup
+- Removed outdated step-by-step documentation
+- Removed planning documents that are now implemented
+- Consolidated into single comprehensive guide
+- Added implementation tracking (this document)
+
+### Code Standards
+- **100% TypeScript** with strict type checking
+- **Emoji-free interface** using only lucide icons
+- **Consistent naming** following project conventions
+- **Proper error handling** with user-friendly messages
+- **Accessibility support** with keyboard navigation
+
+## Database Schema Changes
+
+### New Tables
+```sql
+-- Robot plugin registry
+CREATE TABLE hs_robot_plugin (
+  id UUID PRIMARY KEY,
+  name VARCHAR(255) NOT NULL,
+  version VARCHAR(50) NOT NULL,
+  -- ... plugin metadata
+);
+
+-- Block type registry  
+CREATE TABLE hs_block_registry (
+  id UUID PRIMARY KEY,
+  block_type VARCHAR(100) NOT NULL,
+  plugin_id UUID REFERENCES hs_robot_plugin(id),
+  shape block_shape_enum NOT NULL,
+  category block_category_enum NOT NULL,
+  -- ... block definition
+);
+```
+
+### Enhanced Experiments Table
+```sql
+ALTER TABLE hs_experiment ADD COLUMN visual_design JSONB;
+ALTER TABLE hs_experiment ADD COLUMN execution_graph JSONB;
+ALTER TABLE hs_experiment ADD COLUMN plugin_dependencies TEXT[];
+
+CREATE INDEX experiment_visual_design_idx ON hs_experiment 
+USING gin (visual_design);
+```
+
+### New Enums
+```sql
+CREATE TYPE block_shape_enum AS ENUM (
+  'action', 'control', 'value', 'boolean', 'hat', 'cap'
+);
+
+CREATE TYPE block_category_enum AS ENUM (
+  'wizard', 'robot', 'control', 'sensor', 'logic', 'event'
+);
+```

+## Technical Implementation
+
+### **Data Structure**
+```typescript
+interface ExperimentBlock {
+  id: string;                    // Unique identifier
+  type: string;                  // Block type (e.g., 'robot_speak')
+  category: BlockCategory;       // Visual category
+  shape: BlockShape;             // Visual shape
+  displayName: string;           // User-friendly name
+  description: string;           // Help text
+  icon: string;                  // Lucide icon name
+  color: string;                 // Category color
+  parameters: BlockParameter[]; // Configurable values
+  children?: ExperimentBlock[];  // Nested blocks (for control)
+  nestable?: boolean;           // Can contain children
+  order: number;                // Sequence position
+}
+```
+
+### **Plugin Architecture**
+The block system supports extensible plugins for different robot platforms:
+
+```typescript
+interface PluginBlockDefinition {
+  type: string;                  // Unique block identifier
+  shape: BlockShape;             // Visual representation
+  category: BlockCategory;       // Palette category
+  displayName: string;           // User-visible name
+  description: string;           // Help description
+  icon: string;                  // Icon identifier
+  color: string;                 // Category color
+  parameters: ParameterSchema[]; // Configuration schema
+  nestable?: boolean;           // Supports nesting
+}
+```
+
+### **Execution Integration**
+Visual blocks compile to executable trial sequences:
+
+1. **Design Phase**: Visual blocks stored as JSON in database
+2. **Compilation**: Blocks converted to execution graph
+3. **Runtime**: Trial executor processes blocks sequentially
+4. **Monitoring**: Real-time status updates back to visual blocks
+
+## Best Practices
+
+### **For Simple Experiments**
+- Start with a clear event trigger (`when trial starts`)
+- Use linear sequences for straightforward protocols
+- Add timing blocks (`wait`) for natural pacing
+- Include observation blocks for data collection
+- Keep nesting minimal for clarity
+
+### **For Complex Experiments**
+- Group related actions in control blocks (`repeat`, `if`)
+- Use descriptive parameter values
+- Test conditional logic thoroughly before trials
+- Document unusual configurations in experiment notes
+- Break complex flows into smaller, testable segments
+
+### **For Team Collaboration**
+- Use consistent naming conventions across experiments
+- Export and share protocol designs
+- Review block sequences visually before implementation
+- Maintain version history of experimental protocols
+- Train team members on block meanings and usage
+
+### **Parameter Configuration**
+- Use clear, descriptive text for speech blocks
+- Set appropriate timing for wait blocks (not too fast/slow)
+- Choose realistic movement distances for robot actions
+- Configure observation durations based on expected behaviors
+- Test parameter values in pilot sessions
+
+### **Parameters in Block Drawer**
+Parameter names are currently shown as badges in the block library for preview:
+- **Parameter badges**: Shows first 2 parameter names under each block
+- **Overflow indicator**: Shows "+X more" for blocks with many parameters  
+- **Visual preview**: Helps identify block configuration needs
+- **Future enhancement**: Could support inline editing for rapid prototyping
+
+## Keyboard Shortcuts

+- **Performance**: Efficient rendering for experiments up to 50+ blocks
+
+## Troubleshooting
+
+### **Common Issues**
+
+**Blocks won't drag:**
+- Ensure you're dragging from the grip handle (not the block body)
+- Check that browser supports modern drag and drop APIs
+- Try refreshing the page if drag state gets stuck
+
+**Parameters not saving:**
+- Click outside parameter fields to trigger save
+- Check network connection for auto-save functionality
+- Verify you have edit permissions for the experiment
+
+**Control blocks not nesting:**
+- Drag blocks specifically onto the dashed drop zone
+- Ensure control blocks are expanded (not collapsed)
+- Check that target block supports nesting
+
+**Missing blocks in palette:**
+- Verify required robot plugins are installed and active
+- Check that you have access to the block category
+- Refresh page to reload block registry
+
+### **Breadcrumb Navigation** 
+The block designer integrates with the existing dashboard breadcrumb system:
+- **Path**: Dashboard → Experiments → [Experiment Name] → Designer
+- **Header integration**: Breadcrumbs appear in dashboard header (not duplicated)
+- **Context preservation**: Maintains navigation state during design sessions
+- **Automatic cleanup**: Breadcrumbs reset when leaving designer
+
+### **Performance Tips**

+  // Fallback to minimal blocks if loading fails
+}
+```
+
+#### **Public Serving**

+
+### **5. Quality Assurance**
+
+#### **Validation System**
+- JSON schema validation for all block definitions
+- Type consistency checking (category colors, required fields)
+- Parameter validation (types, constraints, options)
+- Comprehensive test coverage
+
+#### **Test Results**
+```
+✅ All tests passed! Core blocks system is working correctly.
+   • 26 blocks loaded from repository
+   • All required core blocks present
+   • Registry loading simulation successful
+```
+
+#### **TypeScript Compliance**
+- Fixed all unsafe `any` type usage
+- Proper type definitions for all block structures
+- Nullish coalescing operators throughout
+- No compilation errors or warnings
+
+### **6. Benefits Achieved**
+
+#### **Complete Consistency**

+- Consistent block palette organization
+
+#### **Database Integration**
+- Core blocks can be seeded as plugins if needed
+- Compatible with existing plugin management system
+- Study-scoped installations possible
+
+#### **Future Extensibility**
+- Easy to create additional core repositories
+- Simple to add new block categories
+- Version management ready
+
+## **Technical Specifications**
+
+### **Block Definition Schema**
+```json
+{
+  "id": "block_identifier",
+  "name": "Display Name",
+  "description": "Block description",
+  "category": "event|wizard|control|sensor",
+  "shape": "hat|action|control|boolean|value",
+  "icon": "LucideIconName",
+  "color": "#hexcolor",
+  "parameters": [...],
+  "execution": {...}
+}
+```
+
+### **Loading Process**
+1. Component mount triggers `loadCoreBlocks()`
+2. Fetch each block set from `/hristudio-core/plugins/`
+3. Validate JSON structure and block definitions
+4. Convert to `PluginBlockDefinition` format
+5. Register with `BlockRegistry`
+6. Fallback to minimal blocks if any failures
+
+### **Error Handling**
+- Network failures → fallback blocks
+- Invalid JSON → skip block set with warning
+- Invalid blocks → skip individual blocks
+- Type errors → graceful degradation
+

+  ) INTO v_has_permission;
+  
+  RETURN v_has_permission;
+END;
+$$ LANGUAGE plpgsql;
+```
+
+## Migration Notes
+
+1. Tables should be created in the order listed to respect foreign key constraints
+2. Sensitive data in `participants`, `participant_consents`, and related tables should use PostgreSQL's pgcrypto extension for encryption
+3. Consider partitioning large tables like `sensor_data` and `trial_events` by date for better performance
+4. Implement regular vacuum and analyze schedules for optimal performance
+5. Set up appropriate backup strategies for both PostgreSQL and MinIO data

+# Experiment Designer Redesign (Production Baseline)
+
+This document defines the production-ready redesign of the Experiment Designer. It supersedes prior "modular refactor" notes and consolidates architecture, hashing, drift detection, UI/UX, state management, validation, plugin integration, saving/versioning, and export strategy. All implementation must adhere to this specification to ensure reproducibility, extensibility, and maintainability.
+
+---
+
+## 1. Goals
+
+- Provide a clear, fast, and intuitive hierarchical design workflow.
+- Guarantee reproducibility via deterministic hashing and provenance retention.
+- Surface plugin dependency health and schema drift early.
+- Support scalable experiments (many steps/actions) without UI degradation.
+- Enable structured validation (structural, parameter-level, semantic) before compilation.
+- Provide robust export/import and future multi-user collaboration readiness.
+- Maintain 100% type safety and consistent design patterns across the platform.
+
+---
+
+## 2. Conceptual Model
+
+Hierarchy:
+```
+Experiment
+  └─ Step (ordered, typed)
+        └─ Action (ordered, typed, provenance-bound)
+```
+
+Key invariants:
+- Step `order` is zero-based, contiguous after any mutation.
+- Action `orderIndex` is zero-based within its parent step.
+- Each action retains provenance: `{ source.kind, pluginId?, pluginVersion?, baseActionId? }`
+- Execution descriptors are retained for reproducibility (`transport`, `ros2`, `rest`, `retryable`, `timeoutMs`).
+
+---
+
+## 3. Hashing & Integrity Guarantees
+
+### 3.1 Purposes of Hashing
+- Detect structural drift between persisted design and working edits.
+- Bind design to plugin and action schemas for reproducibility.
+- Support execution graph provenance (hash at compile time).
+- Enable export integrity and offline verification.
+
+### 3.2 Design Hash Components
+Included:
+- Steps (ordered): `id`, `name`, `type`, `order`, `trigger.type`, sorted trigger condition keys.
+- Actions (per step, ordered): `id`, `type`, `source.kind`, `pluginId`, `pluginVersion`, `baseActionId`, `execution.transport`, parameter key set (NOT values by default—configurable).
+- Optional: parameter values (toggle design mode if needed—default: exclude values to reduce false-positive drift).
+
+Excluded:
+- Ephemeral UI state (`expanded`, selection state).
+- Human-friendly timestamps or transient meta.
+
+### 3.3 Canonicalization Steps
+1. Deep clone design subset.
+2. Remove `undefined` keys.
+3. Sort object keys recursively.
+4. Sort arrays where semantic ordering is not meaningful (e.g. condition key sets).
+5. JSON stringify (no whitespace).
+6. SHA-256 digest → hex.
+
+### 3.4 Incremental Hash Optimization
+Per-action hash → per-step hash → design hash:
+```
+H_action = hash(canonical(actionMeta))
+H_step = hash(stepMeta + concat(H_action_i))
+H_design = hash(globalMeta + concat(H_step_i))
+```
+Recompute only modified branches for responsiveness.
+
+### 3.5 Drift States
+| State        | Condition                                                                                          |
+|--------------|----------------------------------------------------------------------------------------------------|
+| Unvalidated  | No validation performed since load                                                                 |
+| Validated    | Last validated hash matches stored experiment integrity hash and working snapshot unchanged        |
+| Drift        | (A) Working snapshot changed since last validation OR (B) validated hash ≠ stored integrity hash   |
+| Plugin Drift | Design validated, but one or more action definitions (schema/provenance) no longer match registry  |
+
+### 3.6 Plugin Signature Drift
+Signature hash per action definition: hash of `(type + category + parameterSchema + transport + baseActionId + pluginVersion)`.
+- If signature mismatch for existing action instance: mark as “schema drift”.
+- Provide reconciliation CTA to refetch schema and optionally run migration.
+
+---
+
+## 4. UI Architecture
+
+High-level layout:
+
+```
+┌───────────────────────────────────────────────────────────────────────────┐
+│ Header: breadcrumbs • experiment name • hash badge • plugin deps summary  │
+├──────────────┬───────────────────────────────┬────────────────────────────┤
+│ Action       │ Step Flow (sortable linear)   │ Properties / Inspector      │
+│ Library      │ - Step cards (collapsible)     │ - Step editor               │
+│ - Search     │ - Inline action list           │ - Action parameters         │
+│ - Categories │ - DnD (steps/actions/library)  │ - Validation & drift panel  │
+│ - Plugins    │ - Structural markers           │ - Dependencies & provenance │
+├──────────────┴───────────────────────────────┴────────────────────────────┤
+│ Bottom Save Bar: dirty state • versioning • export • last saved • conflicts│
+└───────────────────────────────────────────────────────────────────────────┘
+```
+
+Component responsibilities:
+| Component                     | Responsibility |
+|------------------------------|----------------|
+| `DesignerRoot`               | Data loading, permission guard, store boot |
+| `ActionLibraryPanel`         | Search/filter, categorized draggable items |
+| `FlowWorkspace`              | Rendering + reordering steps & actions |
+| `StepCard`                   | Step context container |
+| `ActionItem`                 | Visual + selectable action row |
+| `PropertiesPanel`            | Context editing (step/action) |
+| `ParameterFieldFactory`      | Schema → control mapping |
+| `ValidationPanel`            | Issue listing + filtering |
+| `DependencyInspector`        | Plugin + action provenance health |
+| `BottomStatusBar`            | Hash/drift/dirtiness/export/version controls |
+| `hashing.ts`                 | Canonicalization + incremental hashing |
+| `validators.ts`              | Rule execution (structural, parameter) |
+| `exporters.ts`               | Export bundle builder |
+| `store/useDesignerStore.ts`  | Central state store |
+
+---
+
+## 5. State Management
+
+Use a lightweight, framework-agnostic, fully typed store (Zustand). Core fields:
+
+```
+{
+  steps: ExperimentStep[]
+  dirty: Set<string>
+  selectedStepId?: string
+  selectedActionId?: string
+  lastPersistedHash?: string
+  lastValidatedHash?: string
+  lastValidatedSnapshot?: string
+  pluginSignatureIndex: Record<actionTypeOrId, string>
+  validationIssues: Record<entityId, string[]>
+  pendingSave?: boolean
+  conflict?: { serverHash: string; localHash: string }
+}
+```
+
+### Actions
+- `setSteps`, `upsertStep`, `removeStep`, `reorderStep`
+- `upsertAction`, `removeAction`, `reorderAction`
+- `markDirty(entityId)`
+- `computeDesignHash()`
+- `setValidationResult({ hash, issues, snapshot })`
+- `applyServerSync({ steps, hash })`
+- `recordConflict(serverHash, localHash)`
+
+---
+
+## 6. Drag & Drop
+
+Library → Step
+- Drag action definition placeholder onto step drop zone triggers action instantiation.
+Step reorder
+- Sortable vertical list with keyboard accessibility.
+Action reorder
+- Sortable within a step (no cross-step move initially; future extension).
+Framework: `@dnd-kit/core` + `@dnd-kit/sortable`.
+
+Accessibility:
+- Custom keyboard handlers: Up/Down to move selection; Alt+Up/Down to reorder.
+
+---
+
+## 7. Parameters & Control Mapping
+
+Mapping:
+| Schema Type | Control |
+|-------------|---------|
+| boolean     | Switch |
+| number (bounded) | Slider + numeric display |
+| number (unbounded) | Numeric input |
+| text short  | Text input |
+| text long   | Textarea (expandable) |
+| select/enumeration | Select / Combobox |
+| multi-select | Tag list (future) |
+| json/object | Lazy code editor (future) |
+
+Enhancements:
+- Show required indicator
+- Inline validation message
+- Revert-to-default button if default provided
+- Modified badge (dot) for overridden parameters
+
+---
+
+## 8. Validation System
+
+Levels:
+1. Structural
+   - No empty step names
+   - Steps must have valid `type`
+   - Conditional/loop must define required condition semantics
+2. Parameter
+   - Required values present
+   - Number bounds enforced
+   - Enum membership
+3. Semantic
+   - No unresolved plugin dependency
+   - Unique action IDs and step IDs
+   - Loop guard presence (future)
+4. Execution Preflight (optional)
+   - Detect obviously irrecoverable execution (e.g. empty parallel block)
+
+Severity classification:
+- Error: blocks save/compile
+- Warning: surfaced but non-blocking
+- Info: advisory (e.g. unused parameter)
+
+Store format:
+```
+validationIssues: {
+  [entityId: string]: { severity: "error" | "warning" | "info"; message: string }[]
+}
+```
+
+Rendering:
+- Badge on step/actions with count + highest severity color.
+- Panel filter toggles (Errors / Warnings / All).
+- Inline icon markers.
+
+---
+
+## 9. Plugin Integration & Drift
+
+Definitions loaded into `ActionRegistry`:
+```
+{
+  id,
+  type,
+  name,
+  category,
+  parameters[],
+  source: { kind, pluginId?, pluginVersion?, baseActionId? },
+  execution?,
+  parameterSchemaRaw
+}
+```
+
+Per-definition signatureHash computed:
+`hash(type + category + JSON(parameterSchemaRaw) + execution.transport + baseActionId + pluginVersion)`
+
+Per-action drift logic:
+- If action.source.pluginVersion missing in registry → Blocked (hard drift).
+- If signatureHash mismatch → Soft drift (allow edit, prompt reconcile).
+- Provide “Reconcile” overlay listing changed parameters (added / removed / type changed).
+
+---
+
+## 10. Saving & Versioning
+
+Save triggers:
+- Manual (primary save button or Cmd+S)
+- Debounced auto-save (idle > 5s, no pending errors)
+- Forced save before export
+
+Payload:
+```
+{
+  id,
+  visualDesign: { steps, version, lastSaved },
+  createSteps: true,
+  compileExecution: true
+}
+```
+
+Version management:
+- If structural change (add/remove/reorder step/action or change type) → version bump (auto unless user disables).
+- Parameter-only changes may optionally not bump version (configurable toggle; default: no bump).
+- UI: dropdown / toggle “Increment version on save”.
+
+Conflict detection:
+- Server returns persisted integrityHash.
+- If local lastPersistedHash differs and serverHash differs from our pre-save computed hash → conflict modal.
+- Provide:
+  - View diff summary (step added/removed, action count deltas).
+  - Override server (if authorized) or Reload.
+
+---
+
+## 11. Export / Import
+
+Export bundle structure:
+```json
+{
+  "format": "hristudio.design.v1",
+  "exportedAt": "...ISO8601...",
+  "experiment": {
+    "id": "...",
+    "name": "...",
+    "version": 4,
+    "integrityHash": "...",
+    "steps": [... canonical steps ...],
+    "pluginDependencies": ["pluginA@1.2.1", "robot.voice@0.9.3"]
+  },
+  "compiled": {
+    "graphHash": "...",
+    "steps": 12,
+    "actions": 47,
+    "plan": { /* normalized execution nodes */ }
+  }
+}
+```
+
+Import validation:
+- Check `format` signature & version.
+- Recompute design hash vs embedded.
+- Check plugin availability (list missing).
+- Offer “Install required plugins” if privileges allow.
+
+---
+
+## 12. Accessibility & UX Standards
+
+- Keyboard traversal (Tab / Arrow) across steps & actions.
+- Focus ring on selected entities.
+- ARIA labels on all interactive controls (drag handles, add buttons).
+- Color usage passes contrast (WCAG 2.1 AA).
+- Non-color indicators for drift (icons / labels).
+- All icons: Lucide only.
+
+---
+
+## 13. Performance Considerations
+
+- Virtualize StepFlow when step count > threshold (e.g. 50).
+- Memoize parameter forms (avoid re-render on unrelated step changes).
+- Incremental hashing—avoid full recompute on each keystroke.
+- Lazy-load advanced components (JSON editor, large schema viewers).
+
+---
+
+## 14. Testing Strategy
+
+Unit Tests:
+- Hash determinism (same structure -> same hash).
+- Hash sensitivity (reorder step / change action type -> different hash).
+- Signature drift detection logic.
+- Validation rule coverage (structural & parameter).
+
+Integration Tests:
+- Save cycle (design → save → fetch → hash equality).
+- Plugin dependency missing scenario.
+- Conflict resolution workflow.
+
+Edge Cases:
+- Empty experiment (0 steps) → validation error.
+- Conditional step with no conditions → error.
+- Loop step missing guard → warning (future escalation).
+- Plugin removed post-design → plugin drift surfaced.
+
+---
+
+## 15. Migration Plan (Internal) - COMPLETE ✅
+
+1. ✅ Introduce new store + hashing modules.
+2. ✅ Replace current `BlockDesigner` usage with `DesignerRoot`.
+3. ✅ Port ActionLibrary / StepFlow / PropertiesPanel to new contract (`ActionLibraryPanel`, `FlowWorkspace`, `InspectorPanel`).
+4. ✅ Add BottomStatusBar + drift/UI overlays.
+5. ✅ Remove deprecated legacy design references and components.
+6. ✅ Update docs cross-links (`project-overview.md`, `implementation-details.md`).
+7. Add export/import UI.
+8. Stabilize, then enforce hash validation before trial creation.
+
+---
+
+## 16. Security & Integrity
+
+- Server must recompute its own structural hash during compile to trust design.
+- Client-submitted integrityHash considered advisory; never trusted alone.
+- Plugin versions pinned explicitly inside actions (no implicit latest resolution).
+- Attempting to execute an experiment with unresolved drift prompts required validation.
+
+---
+
+## 17. Future Extensions
+
+| Feature                  | Description |
+|--------------------------|-------------|
+| Real-time co-editing     | WebSocket presence + granular patch sync |
+| Branching workflows      | Conditional branches forming DAG (graph mode) |
+| Step templates library   | Shareable reproducible step/action sets |
+| Parameter presets        | Save named parameter bundles per action type |
+| Timeline estimation view | Aggregate predicted duration |
+| Replay / provenance diff | Compare two design versions side-by-side |
+| Plugin action migration  | Scripted param transforms on schema changes |
+| Execution simulation     | Dry-run graph traversal with timing estimates |
+
+---
+
+## 18. Implementation Checklist (Actionable)
+
+- [x] hashing.ts (canonical + incremental)
+- [x] validators.ts (structural + param rules)
+- [x] store/useDesignerStore.ts
+- [x] layout/PanelsContainer.tsx — Tailwind-first grid (fraction-based), strict overflow containment, non-persistent
+- [x] Drag-resize for panels — fraction CSS variables with hard clamps (no localStorage)
+- [x] DesignerRoot layout — status bar inside bordered container (no bottom gap), min-h-0 + overflow-hidden chain
+- [x] ActionLibraryPanel — internal scroll only (panel scroll, not page)
+- [x] InspectorPanel — single Tabs root for header+content; removed extra border; grid tabs header
+- [x] Tabs (shadcn) — restored stock component; globals.css theming for active state
+
+---
+
+## 19. Layout & Overflow Refactor (2025‑08)
+
+Why:
+- Eliminate page-level horizontal scrolling and snapping
+- Ensure each panel scrolls internally while the page/container never does on X
+- Remove brittle width persistence and hard-coded pixel widths
+
+Key rules (must follow):
+- Use Tailwind-first CSS Grid for panels; ratios, not pixels
+  - PanelsContainer sets grid-template-columns with CSS variables (e.g., --col-left/center/right)
+  - No hard-coded px widths in panels; use fractions and minmax(0, …)
+- Strict overflow containment chain:
+  - Dashboard content wrapper: flex, min-h-0, overflow-hidden
+  - DesignerRoot outer container: flex, min-h-0, overflow-hidden
+  - PanelsContainer root: grid, h-full, min-h-0, w-full, overflow-hidden
+  - Panel wrapper: min-w-0, overflow-hidden
+  - Panel content: overflow-y-auto, overflow-x-hidden
+- Status Bar:
+  - Lives inside the bordered designer container
+  - No gap between panels area and status bar (status bar is flex-shrink-0 with border-t)
+- No persistence:
+  - Remove localStorage panel width persistence to avoid flash/snap on load
+- No page-level X scroll:
+  - If X scroll appears, fix the child (truncate/break-words/overflow-x-hidden), not the container
+
+Container chain snapshot:
+- Dashboard layout: header + content (p-4, pt-0, overflow-hidden)
+- DesignerRoot: flex column; PageHeader (shrink-0) + main bordered container (flex-1, overflow-hidden)
+- PanelsContainer: grid with minmax(0, …) columns; internal y-scroll per panel
+- BottomStatusBar: inside bordered container (no external spacing)
+
+---
+
+## 20. Inspector Tabs (shadcn) Resolution
+
+Symptoms:
+- Active state not visible in right panel tabs despite working elsewhere
+
+Root cause:
+- Multiple Tabs roots and extra wrappers around triggers prevented data-state propagation/styling
+
+Fix:
+- Use a single Tabs root to control both header and content
+- Header markup mirrors working example (e.g., trials analysis):
+  - TabsList: grid w-full grid-cols-3 (or inline-flex with bg-muted and p-1)
+  - TabsTrigger: stock shadcn triggers (no Tooltip wrapper around the trigger itself)
+- Remove right-panel self border when container draws dividers (avoid double border)
+- Restore stock shadcn/ui Tabs component via generator; theme via globals.css only
+
+Do:
+- Keep Tabs value/onValueChange at the single root
+- Style active state via globals.css selectors targeting data-state="active"
+
+Don’t:
+- Wrap TabsTrigger directly in Tooltip wrappers (use title or wrap outside the trigger)
+- Create nested Tabs roots for header vs content
+
+---
+
+## 21. Drag‑Resize Panels (Non‑Persistent)
+
+Approach:
+- PanelsContainer exposes drag handles at left/center and center/right separators
+- Resize adjusts CSS variables for grid fractions:
+  - --col-left, --col-center, --col-right (sum ~ 1)
+- Hard clamps ensure usable panels and avoid overflow:
+  - left in [minLeftPct, maxLeftPct], right in [minRightPct, maxRightPct]
+  - center = 1 − (left + right), with a minimum center fraction
+
+Accessibility:
+- Handles are buttons with role="separator", aria-orientation="vertical"
+- Keyboard: Arrow keys resize (Shift increases step)
+
+Persistence:
+- None. No localStorage. Prevents snap-back and layout flash on load
+
+Overflow:
+- Grid and panels keep overflow-x hidden at every level
+- Long content in a panel scrolls vertically within that panel only
+
+---
+
+## 22. Tabs Theming (Global)
+
+- Use globals.css to style shadcn Tabs consistently via data attributes:
+  - [data-slot="tabs-list"]: container look (bg-muted, rounded, p-1)
+  - [data-slot="tabs-trigger"][data-state="active"]: bg/text/shadow (active contrast)
+- Avoid component-level overrides unless necessary; prefer global theme tokens (background, foreground, muted, accent)
+
+- [x] ActionRegistry rewrite with signature hashing
+- [x] ActionLibraryPanel (search, categories, drift indicators)
+- [x] FlowWorkspace + StepCard + ActionItem (DnD with @dnd-kit)
+- [x] PropertiesPanel + ParameterFieldFactory
+- [x] ValidationPanel + badges
+- [x] DependencyInspector + plugin drift mapping
+- [x] BottomStatusBar (dirty, versioning, export)
+- [ ] Exporter (JSON bundle) + import hook
+- [ ] Conflict modal
+- [ ] Drift reconciliation UI
+- [ ] Unit & integration tests
+- [x] Docs cross-link updates
+- [x] Remove obsolete legacy code paths

+## 20. Summary
+
+This redesign formalizes a production-grade, reproducible, and extensible experiment design environment with deterministic hashing, plugin-aware action provenance, structured validation, export integrity, and a modular, performance-conscious UI framework. Implementation should now proceed directly against this spec; deviations require documentation updates and justification.

+# Experiment Designer Step Integration (Modular Architecture + Drift Handling)
+
+## Overview
+
+The HRIStudio experiment designer has been redesigned with a step-based + provenance-aware architecture that provides intuitive experiment creation, transparent plugin usage, and reproducible execution through integrity hashing and a compiled execution graph.
+
+## Architecture
+
+### Core Design Philosophy
+
+The designer follows a clear hierarchy that matches database structure, runtime execution, and reproducibility tracking:
+- **Experiment** → **Steps** → **Actions** (with provenance + execution descriptors)
+- Steps are primary containers in the flow (Step 1 → Step 2 → Step 3) with sortable ordering
+- Actions are dragged from a categorized library into step containers (core vs plugin clearly labeled)
+- Direct 1:1 mapping to database `steps` and `actions` tables, persisting provenance & transport metadata
+
+### Key Components (Post-Modularization)
+
+#### ActionRegistry (`ActionRegistry.ts`)
+- Loads actions from core plugin repositories (`hristudio-core/plugins/`)
+- Integrates study-scoped robot plugins (namespaced: `pluginId.actionId`)
+- Provides fallback actions if plugin loading fails (ensures minimal operability)
+- Maps plugin parameter schemas (primitive: text/number/select/boolean) to UI fields
+- Retains provenance + execution descriptors (transport, timeout, retryable)
+
+#### Step-Based Flow (`StepFlow.tsx`)
+- Sortable step containers with drag-and-drop reordering (via `@dnd-kit`)
+- Color-coded step types (sequential, parallel, conditional, loop) with left border accent
+- Expandable/collapsible view for managing complex experiments
+- Visual connectors between steps (light vertical separators)
+- Isolated from parameter/editor logic for performance and clarity
+
+#### Action Library (`ActionLibrary.tsx`)
+- Categorized tabs: Wizard (blue), Robot (emerald), Control (amber), Observation (purple)
+- Tooltips show description, parameters, provenance badge (C core / P plugin)
+- Drag-and-drop from library directly into specific step droppable zones
+- Footer statistics (total actions / category count)
+- Empty + fallback guidance when plugin actions absent
+- Guarantees availability: once the experiment's study context and its installed plugins are loaded, all corresponding plugin actions are registered and appear (guarded against duplicate loads / stale study mismatch)
+- Plugin availability is study-scoped: only plugins installed for the experiment's parent study (via Plugin Store installation) are loaded and exposed; this ensures experiments cannot reference uninstalled or unauthorized plugin actions.
+
+#### Properties Panel (`PropertiesPanel.tsx`)
+- Context-aware: action selection → action parameters; step selection → step metadata; otherwise instructional state
+- Boolean parameters now render as accessible Switch
+- Number parameters with `min`/`max` render as Slider (shows live value + bounds)
+- Number parameters without bounds fall back to numeric input
+- Select/text unchanged; future: enum grouping + advanced editors
+- Displays provenance + transport badges (plugin id@version, transport, retryable)
+
+## User Experience
+
+### Visual Design
+- **Tightened Spacing**: Compact UI with efficient screen real estate usage
+- **Dark Mode Support**: Proper selection states and theme-aware colors
+- **Color Consistency**: Category colors used throughout for visual coherence
+- **Micro-interactions**: Hover states, drag overlays, smooth transitions
+
+### Interaction Patterns
+- **Direct Action Editing**: Click any action to immediately edit properties (no step selection required)
+- **Multi-level Sorting**: Reorder steps in flow, reorder actions within steps
+- **Visual Feedback**: Drop zones highlight, selection states clear, drag handles intuitive
+- **Touch-friendly**: Proper activation constraints for mobile/touch devices
+
+### Properties Panel (Enhanced Parameter Controls)
+- **Action-First Workflow**: Immediate property editing on action selection
+- **Rich Metadata**: Icon, category color, provenance badges (Core/Plugin, transport)
+- **Switch for Boolean**: Improves clarity vs checkbox in dense layouts
+- **Slider for Ranged Number**: Applies when `min` or `max` present (live formatted value)
+- **Graceful Fallbacks**: Plain number input if no bounds; text/select unchanged
+- **Context-Aware**: Step editing (name/type/trigger) isolated from action editing
+
+## Technical Implementation
+
+### Drag and Drop System
+Built with `@dnd-kit` for robust, accessible drag-and-drop:
+
+```typescript
+// Multi-context sorting support
+const handleDragEnd = (event: DragEndEvent) => {
+  // Action from library to step
+  if (activeId.startsWith("action-") && overId.startsWith("step-")) {
+    // Add action to step
+  }
+  
+  // Step reordering in flow
+  if (!activeId.startsWith("action-") && !overId.startsWith("step-")) {
+    // Reorder steps
+  }
+  
+  // Action reordering within step
+  if (!activeId.startsWith("action-") && !overId.startsWith("step-")) {
+    // Reorder actions in step
+  }
+};
+```
+
+### Plugin Integration (Registry-Centric)
+Actions are loaded dynamically from multiple sources with provenance & version retention:
+
+```typescript
+class ActionRegistry {
+  async loadCoreActions() {
+    // Load from hristudio-core/plugins/
+    const coreActionSets = ["wizard-actions", "control-flow", "observation"];
+    // Process and register actions
+  }
+  
+  loadPluginActions(studyId: string, studyPlugins: Array<{plugin: any}>) {
+    // Load robot-specific actions from study plugins
+    // Map parameter schemas to form controls
+  }
+}
+```
+
+### Database & Execution Conversion
+Two-layer conversion:
+1. Visual design → DB steps/actions with provenance & execution metadata
+2. Visual design → Compiled execution graph (normalized actions + transport summary + integrity hash)
+
+```typescript
+function convertStepsToDatabase(steps: ExperimentStep[]): ConvertedStep[] {
+  return steps.map((step, index) => ({
+    name: step.name,
+    type: mapStepTypeToDatabase(step.type),
+    orderIndex: index,
+    conditions: step.trigger.conditions,
+    actions: step.actions.map((action, actionIndex) => ({
+      name: action.name,
+      type: action.type,
+      orderIndex: actionIndex,
+      parameters: action.parameters,
+    })),
+  }));
+}
+```
+
+## Validation & Hash Drift Handling
+A validation workflow now surfaces structural integrity + reproducibility signals:
+
+### Validation Endpoint
+- `experiments.validateDesign` returns:
+  - `valid` + `issues[]`
+  - `integrityHash` (deterministic structural hash from compiled execution graph)
+  - `pluginDependencies` (sorted, namespaced with versions)
+  - Execution summary (steps/actions/transport mix)
+
+### Drift Detection (Client-Side)
+- Local state caches: `lastValidatedHash` + serialized design snapshot
+- Drift conditions:
+  1. Stored experiment `integrityHash` ≠ last validated hash
+  2. Design snapshot changed since last validation (structural or param changes)
+- Badge States:
+  - `Validated` (green outline): design unchanged since last validation and matches stored hash
+  - `Drift` (destructive): mismatch or post-validation edits
+  - `Unvalidated`: no validation performed yet
+
+### Rationale
+- Encourages explicit revalidation after structural edits
+- Prevents silent divergence from compiled execution artifact
+- Future: differentiate structural vs param-only drift (hash currently parameter-key-based)
+
+### Planned Enhancements
+- Hash stability tuning (exclude mutable free-text values if needed)
+- Inline warnings on mutated steps/actions
+- Optional auto-validate on save (configurable)
+
+## Plugin System Integration
+
+### Core Actions
+Loaded from `hristudio-core/plugins/` repositories:
+- **wizard-actions.json**: Wizard speech, gestures, instructions
+- **control-flow.json**: Wait, conditional logic, loops
+- **observation.json**: Behavioral coding, data collection, measurements
+
+### Robot Actions
+Dynamically loaded based on study configuration:
+- Robot-specific actions from plugin repositories
+- Parameter schemas automatically converted to form controls
+- Platform-specific validation and constraints
+
+### Fallback System
+Essential actions available even if plugin loading fails:
+- Basic wizard speech and gesture actions
+- Core control flow (wait, conditional)
+- Simple observation and data collection
+
+## Example Usage
+
+### Creating an Experiment
+1. **Add Steps**: Click "Add Step" to create containers in the experiment flow
+2. **Configure Steps**: Set name, type (sequential/parallel/conditional/loop), triggers
+3. **Drag Actions**: Drag from categorized library into step drop zones
+4. **Edit Properties**: Click actions to immediately edit parameters
+5. **Reorder**: Drag steps in flow, drag actions within steps
+6. **Save**: Direct conversion to database step/action records (provenance & execution metadata persisted)
+
+### Visual Workflow
+```
+Action Library          Experiment Flow              Properties
+┌─────────────┐        ┌──────────────────┐         ┌─────────────┐
+│ [Wizard]    │        │ Step 1: Welcome  │         │ Action:     │
+│ [Robot]     │ -----> │ ├ Wizard Says    │ ------> │ Wizard Says │
+│ [Control]   │        │ ├ Wait 2s        │         │ Text: ...   │
+│ [Observe]   │        │ └ Observe        │         │ Tone: ...   │
+└─────────────┘        └──────────────────┘         └─────────────┘

+# Flow Designer Connections & Ordering System
+
+## Overview
+
+The HRIStudio Flow Designer uses React Flow to provide an intuitive visual interface for connecting and ordering experiment steps. This document explains how the connection system works and why React Flow is the optimal choice for this functionality.
+
+## Why React Flow?
+
+### ✅ **Advantages of React Flow**
+
+1. **Visual Clarity**: Users can see the experiment flow at a glance
+2. **Intuitive Interaction**: Drag-and-drop connections feel natural
+3. **Professional UI**: Industry-standard flow editor interface
+4. **Flexible Layouts**: Non-linear arrangements for complex experiments
+5. **Real-time Feedback**: Immediate visual confirmation of connections
+6. **Zoom & Pan**: Handle large, complex experiments easily
+7. **Accessibility**: Built-in keyboard navigation and screen reader support
+
+### 🔄 **Alternative Approaches Considered**
+
+| Approach | Pros | Cons | Verdict |
+|----------|------|------|---------|
+| **List-based ordering** | Simple to implement | Limited to linear flows | ❌ Too restrictive |
+| **Tree structure** | Good for hierarchies | Complex for parallel flows | ❌ Not flexible enough |
+| **Graph-based UI** | Very flexible | Higher learning curve | ⚠️ React Flow provides this |
+| **Timeline interface** | Good for time-based flows | Poor for conditional logic | ❌ Wrong metaphor |
+
+**Conclusion**: React Flow provides the best balance of power, usability, and visual clarity.
+
+## Connection System
+
+### 🔗 **How Connections Work**
+
+#### **1. Visual Connection Handles**
+```typescript
+// Each step node has input/output handles
+<Handle
+  type="target"
+  position={Position.Left}
+  className="!bg-primary !border-background !h-3 !w-3 !border-2"
+  id="input"
+/>
+<Handle
+  type="source"
+  position={Position.Right}
+  className="!bg-primary !border-background !h-3 !w-3 !border-2"
+  id="output"
+/>
+```
+
+#### **2. Connection Logic**
+- **Source Handle**: Right side of each step (output)
+- **Target Handle**: Left side of each step (input)
+- **Visual Feedback**: Handles highlight during connection attempts
+- **Theme Integration**: Handles use `!bg-primary` for consistent theming
+
+#### **3. Auto-Positioning**
+When steps are connected, the system automatically adjusts positions:
+```typescript
+const handleConnect = useCallback((params: Connection) => {
+  // Automatically position target step to the right of source
+  const updatedPosition = {
+    x: Math.max(sourceStep.position.x + 300, step.position.x),
+    y: step.position.y,
+  };
+});
+```
+
+### 📋 **Connection Rules**
+
+1. **One Input per Step**: Each step can have multiple inputs but should logically follow one primary path
+2. **Multiple Outputs**: Steps can connect to multiple subsequent steps (for parallel or conditional flows)
+3. **No Circular Dependencies**: System prevents creating loops that could cause infinite execution
+4. **Automatic Spacing**: Connected steps maintain minimum 300px horizontal spacing
+
+## Ordering System
+
+### 🔢 **How Ordering Works**
+
+#### **1. Position-Based Ordering**
+```typescript
+// Steps are ordered based on X position (left to right)
+const sortedSteps = [...design.steps].sort(
+  (a, b) => a.position.x - b.position.x
+);
+```
+
+#### **2. Auto-Connection Logic**
+```typescript
+// Automatically connect steps that are close horizontally
+const distance = Math.abs(targetStep.position.x - sourceStep.position.x);
+if (distance < 400) {
+  // Create automatic connection
+}
+```
+
+#### **3. Manual Reordering**
+- **Drag Steps**: Users can drag steps to reposition them
+- **Visual Feedback**: Connections update in real-time
+- **Smart Snapping**: 20px grid snapping for clean alignment
+
+### 🎯 **Ordering Strategies**
+
+#### **Linear Flow** (Most Common)
+```
+[Start] → [Step 1] → [Step 2] → [Step 3] → [End]
+```
+- Simple left-to-right arrangement
+- Auto-connection between adjacent steps
+- Perfect for basic experimental protocols
+

+# Introduction
+
+Human-robot interaction (HRI) is an essential field of study for
+understanding how robots should communicate, collaborate, and coexist
+with people. The development of autonomous behaviors in social robot
+applications, however, offers a number of challenges. The Wizard-of-Oz
+(WoZ) technique has emerged as a valuable experimental paradigm to
+address these difficulties, as it allows experimenters to simulate a
+robot's autonomous behaviors. With WoZ, a human operator (the
+*"wizard"*) can operate the robot remotely, essentially simulating its
+autonomous behavior during user studies. This enables the rapid
+prototyping and continuous refinement of human-robot interactions
+postponing to later the full development of complex robot behaviors.
+
+While WoZ is a powerful paradigm, it does not eliminate all experimental
+challenges. The paradigm is centered on the wizard who must carry out
+scripted sequences of actions. Ideally, the wizard should execute their
+script identically across runs of the experiment with different
+participants. Deviations from the script in one run or another may
+change experimental conditions significantly decreasing the
+methodological rigor of the larger study. This kind of problem can be
+minimized by instrumenting the wizard with a system that prevents
+deviations from the prescribed interactions with the participant. In
+addition to the variability that can be introduced by wizard behaviors,
+WoZ studies can be undermined by technical barriers related to the use
+of specialized equipment and tools. Different robots may be controlled
+or programmed through different systems requiring expertise with a range
+of technologies such as programming languages, development environments,
+and operating systems.
+
+The elaboration and the execution of rigorous and reproducible WoZ
+experiments can be challenging for HRI researchers. Although there do
+exist solutions to support this kind of endeavor, they often rely on
+low-level robot operating systems, limited proprietary platforms, or
+require extensive custom coding, which can restrict their use to domain
+experts with extensive technical backgrounds. The development of our
+work was motivated by the desire to offer a platform that would lower
+the barriers to entry in HRI research with the WoZ paradigm.
+
+Through the literature review described in the next section, we
+identified six categories of desirables to be included in a modern
+system that streamlines the WoZ experimental process: an environment
+that integrates all the functionalities of the system; mechanisms for
+the description of WoZ experiments which require minimal to no coding
+expertise; fine grained, real-time control of scripted experimental runs
+with a variety of robotic platforms; comprehensive data collection and
+logging; a platform-agnostic approach to support a wide range of robot
+hardware; and collaborative features that allow research teams to work
+together effectively.
+
+The design and development of HRIStudio were driven by the desirables
+enumerated above and described in [@OConnor2024], our preliminary
+report. In this work, our main contribution is to demonstrate how a
+system such the one we are developing has significant potential to make
+WoZ experiments easier to carry out, more rigorous, and ultimately
+reproducible. The remainder of this paper is structured as follows. In
+Section [2](#sota){reference-type="ref" reference="sota"}, we establish
+the context for our contribution through a review of recent literature.
+In Section [3](#repchallenges){reference-type="ref"
+reference="repchallenges"}, we discuss the aspects of the WoZ paradigm
+that can lead to reproducibility challenges and in
+Section [4](#arch){reference-type="ref" reference="arch"} we propose
+solutions to address these challenges. Subsequently, in
+Section [5](#workflow){reference-type="ref" reference="workflow"}, we
+describe our solution to create a structure for the experimental
+workflow. Finally, in Section [6](#conclusion){reference-type="ref"
+reference="conclusion"}, we conclude the paper with a summary of our
+contributions, a reflection on the current state of our project, and
+directions for the future.
+
+# Assessment of the State-of-the-Art {#sota}
+
+Over the last two decades, multiple frameworks to support and automate
+the WoZ paradigm have been reported in the literature. These frameworks
+can be categorized according to how they focus on four primary areas of
+interest, which we discuss below as we expose some of the most important
+contributions to the field.
+
+## Technical Infrastructure and Architectures
+
+The foundation of any WoZ framework lies in its technical infrastructure
+and architectural design. These elements determine not only the system's
+capabilities but also its longevity and adaptability to different
+research needs. Several frameworks have focused on providing robust
+technical infrastructures for WoZ experiments.
+
+*Polonius* [@Lu2011] utilizes the modular *Robot Operating System* (ROS)
+platform as its foundation, offering a graphical user interface for
+wizards to define finite-state machine scripts that drive robot
+behaviors. A notable feature is its integrated logging system that
+eliminates the need for post-experiment video coding, allowing
+researchers to record human-robot interactions in real-time as they
+occur. Polonius was specifically designed to be accessible to
+non-programming collaborators, addressing an important accessibility gap
+in HRI research tools.
+
+*OpenWoZ* [@Hoffman2016] takes a different approach with its
+runtime-configurable framework and multi-client architecture, enabling
+evaluators to modify robot behaviors during experiments without
+interrupting the flow. This flexibility allows for dynamic adaptation to
+unexpected participant responses, though it requires programming
+expertise to create customized robot behaviors. The system's
+architecture supports distributed operation, where multiple operators
+can collaborate during an experiment.
+
+## Interface Design and User Experience
+
+The design of an interface for the wizard to control the execution of an
+experiment is important. The qualities of the interface can
+significantly impact both the quality of data collected and the
+longevity of the tool itself. *NottReal* [@Porcheron2020] exemplifies
+careful attention to interface design in its development for voice user
+interface studies. The system makes it easier for the wizard to play
+their role featuring tabbed lists of pre-scripted messages, slots for
+customization, message queuing capabilities, and comprehensive logging.
+Its visual feedback mechanisms mimic commercial voice assistants,
+providing participants with familiar interaction cues such as dynamic
+"orbs" that indicate the system is listening and processing states.
+
+*WoZ4U* [@Rietz2021] prioritizes usability with a GUI specifically
+designed to make HRI studies accessible to non-programmers. While its
+tight integration with Aldebaran's Pepper robot constrains
+generalizability, it demonstrates how specialized interfaces can lower
+barriers to entry for conducting WoZ studies with specific platforms.
+
+## Domain Specialization vs. Generalizability
+
+A key tension in WoZ framework development exists between domain
+specialization and generalizability. Some systems are designed for
+specific types of interactions or robot platforms, offering deep
+functionality within a narrow domain. Others aim for broader
+applicability across various robots and interaction scenarios,
+potentially sacrificing depth of functionalities for breadth.
+
+Pettersson and Wik's [@Pettersson2015] systematic review identified this
+tension as central to the longevity of WoZ tools, that is, their ability
+to remain operational despite changes in underlying technologies. Their
+analysis of 24 WoZ systems revealed that most general-purpose tools have
+a lifespan of only 2-3 years. Their own tool, Ozlab, achieved
+exceptional longevity (15+ years) through three factors: (1) a truly
+general-purpose approach from inception, (2) integration into HCI
+curricula ensuring institutional support, and (3) a flexible wizard
+interface design that adapts to specific experimental needs rather than
+forcing standardization.
+
+## Standardization Efforts and Methodological Approaches
+
+The tension between specialization and generalizability has led to
+increased interest in developing standardized approaches to WoZ
+experimentation. Recent efforts have focused on developing standards for
+HRI research methodology and interaction specification. Porfirio et
+al. [@Porfirio2023] proposed guidelines for an *interaction
+specification language* (ISL), emphasizing the need for standardized
+ways to define and communicate robot behaviors across different
+platforms. Their work introduces the concept of *Application Development
+Environments* (ADEs) for HRI and details how hierarchical modularity and
+formal representations can enhance the reproducibility of robot
+behaviors. These ADEs would provide structured environments for creating
+robot behaviors with varying levels of expressiveness while maintaining
+platform independence.
+
+This standardization effort addresses a critical gap identified in
+Riek's [@Riek2012] systematic analysis of published WoZ experiments.
+Riek's work revealed concerning methodological deficiencies: 24.1% of
+papers clearly described their WoZ simulation as part of an iterative
+design process, 5.4% described wizard training procedures, and 11%
+constrained what the wizard could recognize. This lack of methodological
+transparency hinders reproducibility and, therefore, scientific progress
+in the field.
+
+Methodological considerations extend beyond wizard protocols to the
+fundamental approaches in HRI evaluation. Steinfeld et
+al. [@Steinfeld2009] introduced a complementary framework to the
+traditional WoZ method, which they termed "the Oz of Wizard." While WoZ
+uses human experimenters to simulate robot capabilities, the Oz of
+Wizard approach employs simplified human models to evaluate robot
+behaviors and technologies. Their framework systematically describes
+various permutations of real versus simulated components in HRI
+experiments, establishing that both approaches serve valid research
+objectives. They contend that technological advances in HRI constitute
+legitimate research even when using simplified human models rather than
+actual participants, provided certain conditions are met. This framework
+establishes an important lesson for the development of new WoZ platforms
+like HRIStudio which must balance standardization with flexibility in
+experimental design.
+
+The interdisciplinary nature of HRI creates methodological
+inconsistencies that Belhassein et al. [@Belhassein2019] examine in
+depth. Their analysis identifies recurring challenges in HRI user
+studies: limited participant pools, insufficient reporting of wizard
+protocols, and barriers to experiment replication. They note that
+self-assessment measures like questionnaires, though commonly employed,
+often lack proper validation for HRI contexts and may not accurately
+capture the participants' experiences. Our platform's design goals align
+closely with their recommendations to combine multiple evaluation
+approaches, thoroughly document procedures, and develop validated
+HRI-specific assessment tools.
+
+Complementing these theoretical frameworks, Fraune et al. [@Fraune2022]
+provide practical methodological guidance from an HRI workshop focused
+on study design. Their work organizes expert insights into themes
+covering study design improvement, participant interaction strategies,
+management of technical limitations, and cross-field collaboration. Key
+recommendations include pre-testing with pilot participants and ensuring
+robot behaviors are perceived as intended. Their discussion of
+participant expectations and the "novelty effect\" in first-time robot
+interactions is particularly relevant for WoZ studies, as these factors
+can significantly influence experimental outcomes.
+
+## Challenges and Research Gaps
+
+Despite these advances, significant challenges remain in developing
+accessible and rigorous WoZ frameworks that can remain usable over
+non-trivial periods of time. Many existing frameworks require
+significant programming expertise, constraining their usability by
+interdisciplinary teams. While technical capabilities have advanced,
+methodological standardization lags behind, resulting in inconsistent
+experimental practices. Few platforms provide comprehensive data
+collection and sharing capabilities that enable robust meta-analyses
+across multiple studies. We are challenged to create tools that provide
+sufficient structure for reproducibility while allowing the flexibility
+needed for the pursuit of answers to diverse research questions.
+
+HRIStudio aims to address these challenges with a platform that is
+robot-agnostic, methodologically rigorous, and eminently usable by those
+with less honed technological skills. By incorporating lessons from
+previous frameworks and addressing the gaps identified in this section,
+we designed a system that supports the full lifecycle of WoZ
+experiments, from design through execution to analysis, with an emphasis
+on usability, reproducibility, and collaboration.
+
+# Reproducibility Challenges in WoZ Studies {#repchallenges}
+
+Reproducibility is a cornerstone of scientific research, yet it remains
+a significant challenge in human-robot interaction studies, particularly
+those centered on the Wizard-of-Oz methodology. Before detailing our
+platform design, we first examine the critical reproducibility issues
+that have informed our approach.
+
+The reproducibility challenges affecting many scientific fields are
+particularly acute in HRI research employing WoZ techniques. Human
+wizards may respond differently to similar situations across
+experimental trials, introducing inconsistency that undermines
+reproducibility and the integrity of collected data. Published studies
+often provide insufficient details about wizard protocols,
+decision-making criteria, and response timing, making replication by
+other researchers nearly impossible. Without standardized tools,
+research teams create custom setups that are difficult to recreate, and
+ad-hoc changes during experiments frequently go unrecorded. Different
+data collection methodologies and metrics further complicate cross-study
+comparisons.
+
+As previously discussed, Riek's [@Riek2012] systematic analysis of WoZ
+research exposed significant methodological transparency issues in the
+literature. These documented deficiencies in reporting experimental
+procedures make replication challenging, undermining the scientific
+validity of findings and slowing progress in the field as researchers
+cannot effectively build upon previous work.
+
+We have identified five key requirements for enhancing reproducibility
+in WoZ studies. First, standardized terminology and structure provide a
+common vocabulary for describing experimental components, reducing
+ambiguity in research communications. Second, wizard behavior
+formalization establishes clear guidelines for wizard actions that
+balance consistency with flexibility, enabling reproducible interactions
+while accommodating the natural variations in human-robot exchanges.
+Third, comprehensive data capture through time-synchronized recording of
+all experimental events with precise timestamps allows researchers to
+accurately analyze interaction patterns. Fourth, experiment
+specification sharing capabilities enable researchers to package and
+distribute complete experimental designs, facilitating replication by
+other teams. Finally, procedural documentation through automatic logging
+of experimental parameters and methodological details preserves critical
+information that might otherwise be omitted in publications. These
+requirements directly informed HRIStudio's architecture and design
+principles, ensuring that reproducibility is built into the platform
+rather than treated as an afterthought.
+
+# The Design and Architecture of HRIStudio {#arch}
+
+Informed by our analysis of both existing WoZ frameworks and the
+reproducibility challenges identified in the previous section, we have
+developed several guiding design principles for HRIStudio. Our primary
+goal is to create a platform that enhances the scientific rigor of WoZ
+studies while remaining accessible to researchers with varying levels of
+technical expertise. We have been drive by the goal of prioritizing
+"accessibility" in the sense that the platform should be usable by
+researchers without deep robot programming expertise so as to lower the
+barrier to entry for HRI studies. Through abstraction, users can focus
+on experimental design without getting bogged down by the technical
+details of specific robot platforms. Comprehensive data management
+enables the system to capture and store all generated data, including
+logs, audio, video, and study materials. To facilitate teamwork, the
+platform provides collaboration support through multiple user accounts,
+role-based access control, and data sharing capabilities that enable
+effective knowledge transfer while restricting access to sensitive data.
+Finally, methodological guidance is embedded throughout the platform,
+directing users toward scientifically sound practices through its design
+and documentation. These principles directly address the reproducibility
+requirements identified earlier, particularly the need for standardized
+terminology, wizard behavior formalization, and comprehensive data
+capture.
+
+We have implemented HRIStudio as a modular web application with explicit
+separation of concerns in accordance with these design principles. The
+structure of the application into client and server components creates a
+clear separation of responsibilities and functionalities. While the
+client exposes interactive elements to users, the server handles data
+processing, storage, and access control. This architecture provides a
+foundation for implementing data security through role-based interfaces
+in which different members of a team have tailored views of the same
+experimental session.
+
+As shown in Figure [1](#fig:system-architecture){reference-type="ref"
+reference="fig:system-architecture"}, the architecture consists of three
+main functional layers that work in concert to provide a comprehensive
+experimental platform. The *User Interface Layer* provides intuitive,
+browser-based interfaces for three components: an *Experiment Designer*
+with visual programming capabilities for one to specify experimental
+details, a *Wizard Interface* that grants real-time control over the
+execution of a trial, and a *Playback & Analysis* module that supports
+data exploration and visualization.
+
+The *Data Management Layer* provides database functionality to organize,
+store, and retrieve experiment definitions, metadata, and media assets
+generated throughout an experiment. Since HRIStudio is a web-based
+application, users can access this database remotely through an access
+control system that defines roles such as *researcher*, *wizard*, and
+*observer* each with appropriate capabilities and constraints. This
+fine-grained access control protects sensitive participant data while
+enabling appropriate sharing within research teams, with flexible
+deployment options either on-premise or in the cloud depending on one's
+needs. The layer enables collaboration among the parties involved in
+conducting a user study while keeping information compartmentalized and
+secure according to each party's requirements.
+
+The third major component is the *Robot Integration Layer*, which is
+responsible for translating our standardized abstractions for robot
+control to the specific commands accepted by different robot platforms.
+HRIStudio relies on the assumption that at least one of three different
+mechanisms is available for communication with a robot: a RESTful API,
+standard communication structures provided by ROS, or a plugin that is
+custom-made for that platform. The *Robot Integration Layer* serves as
+an intermediary between the *Data Management Layer* with *External
+Systems* such as robot hardware, external sensors, and analysis tools.
+This layer allows the main components of the system to remain
+"robot-agnostic" pending the identification or the creation of the
+correct communication method and changes to a configuration file.
+
+![HRIStudio's three-layer
+architecture.](assets/diagrams/system-architecture.pdf){#fig:system-architecture
+width="1\\columnwidth"}
+
+In order to facilitate the deployment of our application, we leverage
+containerization with Docker to ensure that every component of HRIStudio
+will be supported by their system dependencies on different
+environments. This is an important step toward extending the longevity
+of the tool and toward guaranteeing that experimental environments
+remain consistent across different platforms. Furthermore, it allows
+researchers to share not only experimental designs, but also their
+entire execution environment should a third party wish to reproduce an
+experimental study.
+
+# Experimental Workflow Support {#workflow}
+
+The experimental workflow in HRIStudio directly addresses the
+reproducibility challenges identified in
+Section [3](#repchallenges){reference-type="ref"
+reference="repchallenges"} by providing standardized structures,
+explicit wizard guidance, and comprehensive data capture. This section
+details how the platform's workflow components implement solutions for
+each key reproducibility requirement.
+
+## Embracing a Hierarchical Structure for WoZ Studies
+
+HRIStudio defines its own standard terminology with a hierarchical
+organization of the elements in WoZ studies as follows.
+
+- At the top level, an experiment designer defines a *study* element,
+  which comprises one or more *experiment* elements.
+
+- Each *experiment* specifies the experimental protocol for a discrete
+  subcomponent of the overall study and comprises one or more *step*
+  elements, each representing a distinct phase in the execution
+  sequence. The *experiment* functions as a parameterized template.
+
+- Defining all the parameters in an *experiment*, one creates a *trial*,
+  which is an executable instance involving a specific participant and
+  conducted under predefined conditions. The data generated by each
+  *trial* is recorded by the system so that later one can examine how
+  the experimental protocol was applied to each participant. The
+  distinction between experiment and trial enables a clear separation
+  between the abstract protocol specification and its concrete
+  instantiation and execution.
+
+- Each *step* encapsulates instructions that are meant either for the
+  wizard or for the robot thereby creating the concept of "type" for
+  this element. The *step* is a container for a sequence of one or more
+  *action* elements.
+
+- Each *action* represents a specific, atomic task for either the wizard
+  or the robot, according to the nature of the *step* element that
+  contains it. An *action* for the robot may represent commands for
+  input gathering, speech, waiting, movement, etc., and may be
+  configured by parameters specific for the *trial*.
+
+Figure [2](#fig:experiment-architecture){reference-type="ref"
+reference="fig:experiment-architecture"} illustrates this hierarchical
+structure through a fictional study. In the diagram, we see a "Social
+Robot Greeting Study" containing an experiment with a specific robot
+platform, steps containing actions, and a trial with a participant. Note
+that each trial event is a traceable record of the sequence of actions
+defined in the experiment. HRIStudio enables researchers to collect the
+same data across multiple trials while adhering to consistent
+experimental protocols and recording any reactions the wizard may inject
+into the process.
+
+![Hierarchical organization of a sample user study in
+HRIStudio.](assets/diagrams/experiment-architecture.pdf){#fig:experiment-architecture
+width="1\\columnwidth"}
+
+This standardized hierarchical structure creates a common vocabulary for
+experimental elements, eliminating ambiguity in descriptions and
+enabling clearer communication among researchers. Our approach aligns
+with the guidelines proposed by Porfirio et al. [@Porfirio2023] for an
+HRI specification language, particularly in regards to standardized
+formal representations and hierarchical modularity. Our system uses the
+formal study definitions to create comprehensive procedural
+documentation requiring no additional effort by the researcher. Beyond
+this documentation, a study definition can be shared with other
+researchers for the faithful reproduction of experiments.
+
+Figure [3](#fig:study-details){reference-type="ref"
+reference="fig:study-details"} shows how the system displays the data of
+an experimental study in progress. In this view, researchers can inspect
+summary data about the execution of a study and its trials, find a list
+of human subjects ("participants") and go on to see data and documents
+associated with them such as consent forms, find the list of teammates
+collaborating in this study ("members"), read descriptive information on
+the study ("metadata"), and inspect an audit log that records work that
+has been done toward the completion of the study ("activity").
+
+![Summary view of system data on an example
+study.](assets/mockups/study-details.png){#fig:study-details
+width="1\\columnwidth"}
+
+## Collaboration and Knowledge Sharing
+
+Experiments are reproducible when they are thoroughly documented and
+when that documentation is easily disseminated. To support this,
+HRIStudio includes features that enable collaborative experiment design
+and streamlined sharing of assets generated during experimental studies.
+The platform provides a dashboard that offers an overview of project
+status, details about collaborators, a timeline of completed and
+upcoming trials, and a list of pending tasks.
+
+As previously noted, the *Data Management Layer* incorporates a
+role-based access control system that defines distinct user roles
+aligned with specific responsibilities within a study. This role
+structure enforces a clear separation of duties and enables
+fine-grained, need-to-know access to study-related information. This
+design supports various research scenarios, including double-blind
+studies where certain team members have restricted access to
+information. The pre-defined roles are as follows:
+
+- *Administrator*, a "super user" who can manage the installation and
+  the configuration of the system,
+
+- *Researcher*, a user who can create and configure studies and
+  experiments,
+
+- *Observer*, a user role with read-only access, allowing inspection of
+  experiment assets and real-time monitoring of experiment execution,
+  and
+
+- *Wizard*, a user role that allows one to execute an experiment.
+
+For maximum flexibility, the system allows additional roles with
+different sets of permissions to be created by the administrator as
+needed.
+
+The collaboration system allows multiple researchers to work together on
+experiment designs, review each other's work, and build shared knowledge
+about effective methodologies. This approach also enables the packaging
+and dissemination of complete study materials, including experimental
+designs, configuration parameters, collected data, and analysis results.
+By making all aspects of the research process shareable, HRIStudio
+facilitates replication studies and meta-analyses, enhancing the
+cumulative nature of scientific knowledge in HRI.

+HRIStudio implements an *Experiment Development Environment* (EDE) that
+builds on Porfirio et al.'s [@Porfirio2023] concept of Application
+Development Environment.
+Figure [4](#fig:experiment-designer){reference-type="ref"
+reference="fig:experiment-designer"} shows how this EDE is implemented
+as a visual programming, drag-and-drop canvas for sequencing steps and
+actions. In this example, we see a progression of steps ("Welcome" and
+"Robot Approach") where each step is customized with specific actions.
+Robot actions issue abstract commands, which are then translated into
+platform-specific concrete commands by components known as *plugins*,
+which are tailored to each type of robot and discussed later in this
+section.
+
+![View of experiment
+designer.](assets/mockups/experiment-designer.png){#fig:experiment-designer
+width="1\\columnwidth"}
+
+Our EDE was inspired by Choregraphe [@Pot2009] which enables researchers
+without coding expertise to build the steps and actions of an experiment
+visually as flow diagrams. The robot control components shown in the
+interface are automatically added to the inventory of options according
+to the experiment configuration, which specifies the robot to be used.
+We expect that this will make experiment design more accessible to those
+with reduced programming skills while maintaining the expressivity
+required for sophisticated studies. Conversely, to support those without
+knowledge of best practices for WoZ studies, the EDE offers contextual
+help and documentation as guidance for one to stay on the right track.
+
+## The Wizard Interface and Experiment Execution
+
+We built into HRIStudio an interface for the wizard to execute
+experiments and to interact with them in real time. In the development
+of this component, we drew on lessons from Pettersson and
+Wik's [@Pettersson2015] work on WoZ tool longevity. From them we have
+learned that a significant factor that determines the short lifespan of
+WoZ tools is the trap of a fixed, one-size-fits-all wizard interface.
+Following the principle incorporated into their Ozlab, we have
+incorporated into our framework functionality that allows the wizard
+interface to be adapted to the specific needs of each experiment. One
+can configure wizard controls and visualizations for their specific
+study, while keeping other elements of the framework unchanged.
+
+Figure [5](#fig:experiment-runner){reference-type="ref"
+reference="fig:experiment-runner"} shows the wizard interface for the
+fictional experiment "Initial Greeting Protocol." This view shows the
+current step with an instruction for the wizard that corresponds to an
+action they will carry out. These instructions are presented one at a
+time so as not to overwhelm the wizard, but one can also use the "View
+More" button when it becomes desirable to see the complete experimental
+script. The view also includes a window for the captured video feed
+showing the robot and the participant, a timestamped log of recent
+events, and various interaction controls for unscripted actions that can
+be applied in real time ("quick actions"). By following the instructions
+which are provided incrementally, the wizard is guided to execute the
+experimental procedure consistently across its different trials with
+different participants. To provide live monitoring functionalities to
+users in the role of *observer*, a similar view is presented to them
+without the controls that might interfere with the execution of an
+experiment.
+
+When a wizard initiates an action during a trial, the system executes a
+three-step process to implement the command. First, it translates the
+high-level action into specific API calls as defined by the relevant
+plugin, converting abstract experimental actions into concrete robot
+instructions. Next, the system routes these calls to the robot's control
+system through the appropriate communication channels. Finally, it
+processes any feedback received from the robot, logs this information in
+the experimental record, and updates the experiment state accordingly to
+reflect the current situation. This process ensures reliable
+communication between the wizard interface and the physical robot while
+maintaining comprehensive records of all interactions.
+
+![View of HRIStudio's wizard interface during experiment
+execution.](assets/mockups/experiment-runner.png){#fig:experiment-runner
+width="1\\columnwidth"}
+
+## Robot Platform Integration {#plugin-store}
+
+The three-step process described above relies on a modular, two-tier
+system for communication between HRIStudio and each specific robot
+platform. The EDE offers an experiment designer a number of pre-defined
+action components representing common tasks and behaviors such as robot
+movements, speech synthesis, and sensor controls. Although these
+components can accept parameters for the configuration of each action,
+they exist at a higher level of abstraction. When actions are executed,
+the system translates these abstractions so that they match the commands
+accepted by the robot selected for the experiment. This translation is
+achieved by a *plugin* for the specific robot, which serves as the
+communication channel between HRIStudio and the physical robots.
+
+Each robot plugin contains detailed action definitions with multiple
+components: action identifiers and metadata such as title, description,
+and a graphical icon to be presented in the EDE. Additionally, the
+plugin is programmed with parameter schemas including data types,
+validation rules, and default values to ensure proper configuration. For
+robots running ROS2, we support mappings that connect HRIStudio to the
+robot middleware. This integration approach ensures that HRIStudio can
+be used with any robot for which a plugin has been built.
+
+As shown in Figure [6](#fig:plugins-store){reference-type="ref"
+reference="fig:plugins-store"}, we have developed a *Plugin Store* to
+aggregate plugins available for an HRIStudio installation. Currently, it
+includes a plugin specifically for the TurtleBot3 Burger (illustrated in
+the figure) as well as a template to support the creation of additional
+plugins for other robots. Over time, we anticipate that the Plugin Store
+will expand to include a broader range of plugins, supporting robots of
+diverse types. In order to let users of the platform know what to expect
+of the plugins in the store, we have defined three different trust
+levels:
+
+- *Official* plugins will have been created and tested by HRIStudio
+  developers.
+
+- *Verified* plugins will have different provenance, but will have
+  undergone a validation process.
+
+- *Community* plugins will have been developed by third-parties but will
+  not yet have been validated.
+
+The Plugin Store provides access to the source version control
+*repositories* which are used in the development of plugins allowing for
+the precise tracking of which plugin versions are used in each
+experiment. This system enables community contributions while
+maintaining reproducibility by documenting exactly which plugin versions
+were used for any given experiment.
+
+![The Plugin Store for plugin
+selection.](assets/mockups/plugins-store.png){#fig:plugins-store
+width="1\\columnwidth"}
+
+## Comprehensive Data Capture and Analysis
+
+We have designed HRIStudio to create detailed logs of experiment
+executions and to capture and place in persistent storage all the data
+generated during each trial. The system keeps timestamped records of all
+executed actions and experimental events so that it is able to create an
+accurate timeline of the study. It collects robot sensor data including
+position, orientation, and various sensor readings that provide context
+about the robot's state throughout the experiment.
+
+The platform records audio and video of interactions between a robot and
+participant, enabling post-hoc analysis of verbal and non-verbal
+behaviors. The system also records wizard decisions and interventions,
+including any unplanned actions that deviate from the experimental
+protocol. Finally, it saves with the experiment the observer notes and
+annotations, capturing qualitative insights from researchers monitoring
+the study. Together, these synchronized data streams provide a complete
+record of experimental sessions.
+
+Experimental data is stored in structured formats to support long-term
+preservation and seamless integration with analysis tools. Sensitive
+participant data is encrypted at the database level to safeguard
+participant privacy while retaining comprehensive records for research
+use. To facilitate analysis, the platform allows trials to be studied
+with "playback" functionalities that allow one to review the steps in a
+trial and to annotate any significant events identified.
+
+# Conclusion and Future Directions {#conclusion}
+
+Although Wizard-of-Oz (WoZ) experiments are a powerful method for
+developing human-robot interaction applications, they demand careful
+attention to procedural details. Trials involving different participants
+require wizards to consistently execute the same sequence of events,
+accurately log any deviations from the prescribed script, and
+systematically manage all assets associated with each participant. The
+reproducibility of WoZ experiments depends on the thoroughness of their
+documentation and the ease with which their experimental setup can be
+disseminated.
+
+To support these efforts, we drew on both existing literature and our
+own experience to develop HRIStudio, a modular platform designed to ease
+the burden on wizards while enhancing the reproducibility of
+experiments. HRIStudio maintains detailed records of experimental
+designs and results, facilitating dissemination and helping third
+parties interested in replication. The platform offers a hierarchical
+framework for experiment design and a visual programming interface for
+specifying sequences of events. By minimizing the need for programming
+expertise, it lowers the barrier to entry and broadens access to WoZ
+experimentation.
+
+HRIStudio is built using a variety of web application and database
+technologies, which introduce certain dependencies for host systems. To
+simplify deployment, we are containerizing the platform and developing
+comprehensive, interface-integrated documentation to guide users through
+installation and operation. Our next development phase focuses on
+enhancing execution and analysis capabilities, including advanced wizard
+guidance, dynamic adaptation, and improved real-time feedback. We are
+also implementing playback functionality for reviewing synchronized data
+streams and expanding integration with hardware commonly used HRI
+research.
+
+Ongoing engagement with the research community has played a key role in
+shaping HRIStudio. Feedback from the reviewers of our RO-MAN 2024 late
+breaking report and conference participants directly influenced our
+design choices, particularly around integration with existing research
+infrastructures and workflows. We look forward to creating more
+systematic opportunities to engage researchers to guide and refine our
+development as we prepare for an open beta release.

+
+### 2.2 tRPC Routes Implementation
+
+**Location**: `src/server/api/routers/plugins.ts`
+
+```typescript
+export const pluginsRouter = createTRPCRouter({
+  // Repository management

+```
+
+### 2.3 Plugin Registry Service
+
+**Location**: `src/lib/plugins/registry.ts`
+
+```typescript
+export class PluginRegistry {
+  // Fetch and validate repository metadata
+  async fetchRepository(url: string): Promise<RepositoryMetadata>
+  
+  // Sync plugins from repository
+  async syncRepository(repositoryId: string): Promise<void>
+  
+  // Load plugin definition

+  async validatePlugin(plugin: PluginDefinition): Promise<ValidationResult>
+  
+  // Install plugin
+  async installPlugin(repositoryId: string, pluginId: string, config?: any): Promise<void>
+}
+```
+
+## Phase 3: Plugin Repository Modifications
+
+### 3.1 Schema Enhancements
+
+**Location**: Plugin Repository - `docs/schema.md`
+
+Update the plugin schema to include HRIStudio-specific fields:
+
+```json

+  "robotId": "string (required)",
+  "name": "string (required)", 
+  "description": "string (optional)",
+  "platform": "string (required)",
+  "version": "string (required)",
+  
+  // Add these HRIStudio-specific fields:

+    }
+  ]
+}
+```
+
+### 3.2 TurtleBot3 Plugin Update

+          }
+        },
+        "required": ["linear", "angular"]
+      },
+      
+      // Keep existing ros2 config
+      "ros2": {
+        "messageType": "geometry_msgs/msg/Twist",
+        "topic": "/cmd_vel",
+        "payloadMapping": {
+          "type": "transform",
+          "transformFn": "transformToTwist"
+        },

+          "depth": 1
+        }
+      }
+    }
+  ]
+}
+```
+
+### 3.3 Repository Metadata Update
+
+**Location**: Plugin Repository - `repository.json`
+
+Add HRIStudio-specific metadata:
+
+```json
+{
+  "id": "hristudio-official",
+  "name": "HRIStudio Official Robot Plugins",
+  "description": "Official collection of robot plugins maintained by the HRIStudio team",
+  
+  // Add API versioning:
+  "apiVersion": "1.0",
+  "pluginApiVersion": "1.0",
+  
+  // Add plugin categories:
+  "categories": [
+    {
+      "id": "mobile-robots",
+      "name": "Mobile Robots", 
+      "description": "Wheeled and tracked mobile platforms"
+    },
+    {
+      "id": "manipulators",
+      "name": "Manipulators",

+    },
+    "ros2": {
+      "distributions": ["humble", "iron"],
+      "recommended": "iron"
+    }
+  }
+}
+```
+
+## Phase 4: Integration Implementation
+
+### 4.1 Experiment Designer Integration
+
+**Location**: HRIStudio - `src/components/experiments/designer/EnhancedBlockDesigner.tsx`
+
+Add plugin-based action loading to the block designer:
+
+```typescript
+// In the block registry, load actions from installed plugins:
+const loadPluginActions = async (studyId: string) => {
+  const installedPlugins = await api.plugins.getStudyPlugins.query({ studyId });
+  
+  for (const plugin of installedPlugins) {
+    const actions = await api.plugins.getPluginActions.query({ 
+      pluginId: plugin.id 
+    });
+    
+    // Register actions in block registry
+    actions.forEach(action => {
+      blockRegistry.register({
+        id: `${plugin.id}.${action.id}`,
+        name: action.name,
+        description: action.description,
+        category: action.category,
+        icon: action.icon || 'bot',
+        shape: 'action',
+        color: getCategoryColor(action.category),
+        parameters: convertToZodSchema(action.parameterSchema),
+        metadata: {
+          pluginId: plugin.id,
+          robotId: plugin.robotId,
+          ros2Config: action.ros2
+        }
+      });
+    });
+  }
+};
+```
+
+### 4.2 Trial Execution Integration
+
+**Location**: HRIStudio - `src/lib/plugins/execution.ts`
+
+Create plugin execution interface:
+
+```typescript
+export class PluginExecutor {
+  private installedPlugins = new Map<string, InstalledPlugin>();
+  private rosConnections = new Map<string, RosConnection>();
+
+  async executePluginAction(
+    pluginId: string, 
+    actionId: string, 
+    parameters: Record<string, any>
+  ): Promise<ActionResult> {
+    const plugin = this.installedPlugins.get(pluginId);
+    if (!plugin) {
+      throw new Error(`Plugin ${pluginId} not found`);
+    }
+
+    const action = plugin.actions.find(a => a.id === actionId);
+    if (!action) {
+      throw new Error(`Action ${actionId} not found in plugin ${pluginId}`);
+    }
+
+    // Validate parameters against schema
+    const validation = this.validateParameters(action.parameterSchema, parameters);
+    if (!validation.success) {
+      throw new Error(`Parameter validation failed: ${validation.error}`);
+    }
+
+    // Execute via ROS2 if configured
+    if (action.ros2) {
+      return this.executeRos2Action(plugin, action, parameters);
+    }
+
+    // Execute via REST API if configured
+    if (action.rest) {
+      return this.executeRestAction(plugin, action, parameters);
+    }
+
+    throw new Error(`No execution method configured for action ${actionId}`);
+  }
+
+  private async executeRos2Action(
+    plugin: InstalledPlugin,
+    action: PluginAction, 
+    parameters: Record<string, any>
+  ): Promise<ActionResult> {
+    const connection = this.getRosConnection(plugin.id);
+

+      return this.publishToTopic(connection, action.ros2, payload);
+    } else if (action.ros2.service) {
+      return this.callService(connection, action.ros2, payload);
+    } else if (action.ros2.action) {
+      return this.executeAction(connection, action.ros2, payload);

+# A Web-Based Wizard-of-Oz Platform for Collaborative and Reproducible Human-Robot Interaction Research
+
+## 1) Introduction
+- HRI needs rigorous methods for studying robot communication, collaboration, and coexistence with people.
+- WoZ: a wizard remotely operates a robot to simulate autonomous behavior, enabling rapid prototyping and iterative refinement.
+- Challenges with WoZ:
+  - Wizard must execute scripted sequences consistently across participants.
+  - Deviations and technical barriers reduce methodological rigor and reproducibility.
+  - Many available tools require specialized technical expertise.
+- Goal: a platform that lowers barriers to entry, supports rigorous, reproducible WoZ experiments, and provides integrated capabilities.
+
+## 2) Assessment of the State-of-the-Art
+- Technical infrastructure and architectures:
+  - Polonius: ROS-based, finite-state machine scripting, integrated logging for real-time event recording; designed for non-programming collaborators.
+  - OpenWoZ: runtime-configurable, multi-client, supports distributed operation and dynamic evaluator interventions (requires programming for behavior creation).
+- Interface design and user experience:
+  - NottReal: interface for voice UI studies; tabbed pre-scripted messages, customization slots, message queuing, comprehensive logging, familiar listening/processing feedback.
+  - WoZ4U: GUI designed for non-programmers; specialized to Aldebaran Pepper (limited generalizability).
+- Domain specialization vs. generalizability:
+  - System longevity is often short (2–3 years for general-purpose tools).
+  - Ozlab’s longevity due to: general-purpose design, curricular integration, flexible wizard UI that adapts to experiments.
+- Standardization and methodological approaches:
+  - Interaction Specification Language (ISL) and ADEs (Porfirio et al.): hierarchical modularity, formal representations, platform independence for reproducibility.
+  - Riek: methodological transparency deficiencies in WoZ literature (insufficient reporting of protocols/training/constraints).
+  - Steinfeld et al.: “Oz of Wizard” complements WoZ; structured permutations of real vs. simulated components; both approaches serve valid objectives.
+  - Belhassein et al.: recurring HRI study challenges (limited participants, inadequate protocol reporting, weak replication); need for validated measures and comprehensive documentation.
+  - Fraune et al.: practical guidance (pilot testing, ensuring intended perception of robot behaviors, managing novelty effects, cross-field collaboration).
+- Remaining challenges:
+  - Accessibility for interdisciplinary teams.
+  - Methodological standardization and comprehensive data capture/sharing.
+  - Balance of structure (for reproducibility) and flexibility (for diverse research questions).
+
+## 3) Reproducibility Challenges in WoZ Studies
+- Inconsistent wizard behavior across trials undermines reproducibility.
+- Publications often omit critical procedural details, making replication difficult.
+- Custom, ad-hoc setups are hard to recreate; unrecorded changes hinder transparency.
+- HRIStudio’s reproducibility requirements (five areas):
+  - Standardized terminology and structure.
+  - Wizard behavior formalization (clear, consistent execution with controlled flexibility).
+  - Comprehensive, time-synchronized data capture.
+  - Experiment specification sharing (package and distribute complete designs).
+  - Procedural documentation (automatic logging of parameters and methodological details).
+
+## 4) The Design and Architecture of HRIStudio
+- Guiding design principles:
+  - Accessibility for researchers without deep robot programming expertise.
+  - Abstraction to focus on experimental design over platform details.
+  - Comprehensive data management (logs, audio, video, study materials).
+  - Collaboration through multi-user accounts, role-based access control, and data sharing.
+  - Embedded methodological guidance to encourage scientifically sound practices.
+- Conceptual separation aligned to research needs:
+  - User-facing tools for design, execution, and analysis; stewarded data and access control; and standardized interfaces to connect experiments with robots and sensors.
+- Three-layer architecture [Screenshot Placeholder: Architecture Overview]:
+  - User Interface Layer:
+    - Experiment Designer (visual programming for specifying experiments).
+    - Wizard Interface (real-time control for trials).
+    - Playback & Analysis (data exploration and visualization).
+  - Data Management Layer:
+    - Structured storage of experiment definitions, metadata, and media.
+    - Role-based access aligned with study responsibilities.
+    - Collaboration with secure, compartmentalized access for teams.
+  - Robot Integration Layer:
+    - Translates standardized abstractions to robot behaviors through plugins.
+    - Standardized plugin interfaces support diverse platforms without changing study designs.
+    - Integrates with external systems (robot hardware, sensors, tools).
+- Sustained reproducibility and sharing:
+  - Study definitions and execution environments can be packaged and shared to support faithful reproduction by independent teams.
+
+## 5) Experimental Workflow Support
+- Directly addresses reproducibility requirements with standardized structures, wizard guidance, and comprehensive capture.
+
+### 5.1 Hierarchical Structure for WoZ Studies
+- Standard terminology and elements:
+  - Study: top-level container with one or more experiments.
+  - Experiment: parameterized protocol template composed of steps.
+  - Trial: concrete, executable instance of an experiment for a specific participant; all trial data recorded.
+  - Step: type-bound container (wizard or robot) comprising a sequence of actions.
+  - Action: atomic task for wizard or robot (e.g., input gathering, speech, movement), parameterized per trial.
+- [Screenshot Placeholder: Experiment Hierarchy Diagram].
+- [Screenshot Placeholder: Study Details View]:
+  - Overview of execution summaries, trials, participant info and documents (e.g., consent), members, metadata, and audit activity.
+
+### 5.2 Collaboration and Knowledge Sharing
+- Dashboard for project overview, collaborators, trial schedules, pending tasks.
+- Role-based access control (pre-defined roles; flexible extensions):
+  - Administrator: system configuration/management.
+  - Researcher: create/configure studies and experiments.
+  - Observer: read-only access and real-time monitoring.
+  - Wizard: execute experiments.
+- Packaging and dissemination of complete materials for replication and meta-analyses.
+
+### 5.3 Visual Experiment Design (EDE)
+- Visual programming canvas for sequencing steps and actions (drag-and-drop).
+- Abstract robot actions translated by plugins into platform-specific commands.
+- Contextual help and documentation in the interface.
+- [Screenshot Placeholder: Experiment Designer].
+- Inspiration: Choregraphe’s flow-based, no-code composition for steps/actions.
+
+### 5.4 Wizard Interface and Experiment Execution
+- Adaptable, experiment-specific wizard UI (avoids one-size-fits-all trap).
+- Incremental instructions, “View More” for full script, video feed, timestamped event log, and “quick actions.”
+- Observer view mirrors wizard interface without execution controls.
+- Action execution process:
+  1) Translate abstract action into robot-specific calls via plugin.
+  2) Route calls through appropriate communication channels.
+  3) Process robot feedback, log details, update experiment state.
+- [Screenshot Placeholder: Wizard Interface].
+
+### 5.5 Robot Platform Integration (Plugin Store)
+- Two-tier abstraction/translation of actions:
+  - High-level action components (movement, speech, sensors) with parameter schemas and validation rules.
+  - Robot plugins implement concrete mappings appropriate to each platform.
+- [Screenshot Placeholder: Plugin Store]:
+  - Trust levels: Official, Verified, Community.
+  - Source repositories for precise version tracking and reproducibility.
+
+### 5.6 Comprehensive Data Capture and Analysis
+- Timestamped logs of all executed actions and events.
+- Robot sensor data (position, orientation, sensor readings).
+- Audio/video recordings of interactions.
+- Wizard decisions/interventions (including unplanned deviations).
+- Observer notes and annotations.
+- Structured storage for long-term preservation and analysis integration.
+- Sensitive participant data encrypted at the database level.
+- Playback for step-by-step trial review and annotation.
+
+## 6) Conclusion and Future Directions
+- HRIStudio supports rigorous, reproducible WoZ experimentation via:
+  - Standardized hierarchy and terminology.
+  - Visual designer for protocol specification.
+  - Configurable wizard interface for consistent execution.
+  - Plugin-based, robot-agnostic integration.
+  - Comprehensive capture and structured storage of multimodal data.
+- Future directions:
+  - Interface-integrated documentation for installation and operation.
+  - Enhanced execution and analysis (advanced guidance, dynamic adaptation, real-time feedback).
+  - Playback for synchronized streams and expanded hardware integration.
+  - Continued community engagement to refine integration with existing research infrastructures and workflows.
+  - Preparation for an open beta release.

+
+## Architecture
+
+### Communication Flow
+
+```
+HRIStudio Web App → WebSocket → rosbridge_server → ROS2 Robot
+                                      ↓
+                              ROS2 Topics/Services
+```
+
+### Key Components

+
+## Security Considerations
+
+### 1. Authentication
+- Use SSL/TLS for rosbridge connections in production
+- Implement token-based authentication for rosbridge
+- Restrict topic/service access patterns
+
+### 2. Network Security
+- Use VPN or SSH tunnels for remote robot connections
+- Implement firewall rules to restrict rosbridge access
+- Use separate network segments for robot communication
+
+### 3. Message Validation
+- Validate all incoming messages on the robot side
+- Implement rate limiting to prevent DoS attacks
+- Sanitize string inputs to prevent injection attacks
+
+## Deployment Considerations
+
+### Local Development
+- Robot and development machine on same network
+- Direct WebSocket connection to rosbridge
+- No SSL required
+
+### Production (Vercel)
+- Robot behind NAT/firewall
+- Use reverse proxy or tunnel (e.g., ngrok, Cloudflare Tunnel)
+- SSL/TLS required for secure communication
+- Consider latency for real-time control
+
+### Hybrid Approach
+- Local "robot companion" server near robot
+- Companion server connects to both robot and Vercel app
+- Reduces latency for critical operations
+- Maintains security boundaries
+
+## Testing ROS2 Integration
+
+### Unit Tests
+
+`src/lib/ros/__tests__/connection.test.ts`:
+
+```typescript
+import { RosConnection } from '../connection';
+import { vi, describe, it, expect, beforeEach } from 'vitest';
+
+vi.mock('roslib', () => ({
+  default: {
+    Ros: vi.fn().mockImplementation(() => ({
+      on: vi.fn(),
+      connect: vi.fn(),
+      close: vi.fn(),
+      isConnected: true,
+    })),
+    Topic: vi.fn(),
+    Service: vi.fn(),
+  },
+}));
+
+describe('RosConnection', () => {
+  let connection: RosConnection;
+
+  beforeEach(() => {
+    connection = new RosConnection('ws://test:9090');
+  });
+
+  it('should connect successfully', async () => {
+    await expect(connection.connect()).resolves.toBeUndefined();
+    expect(connection.isConnected()).toBe(true);
+  });
+
+  // Add more tests...
+});
+```
+
+### Integration Tests
+- Use rosbridge_server in test mode
+- Mock robot responses
+- Test error scenarios
+- Verify message formats
+
+## Performance Optimization
+
+1. **Message Throttling**: Limit frequency of state updates
+2. **Compression**: Enable PNG compression for image topics
+3. **Selective Subscriptions**: Only subscribe to needed topics
+4. **Connection Pooling**: Reuse WebSocket connections
+5. **Client-Side Caching**: Cache robot capabilities
+
+## Troubleshooting
+
+### Common Issues
+
+1. **Connection Refused**
+   - Check rosbridge is running
+   - Verify firewall rules
+   - Check WebSocket URL
+
+2. **Message Type Errors**
+   - Ensure message types match between client and robot
+   - Verify ROS2 workspace is sourced
+
+3. **High Latency**
+   - Check network conditions
+   - Consider local rosbridge proxy
+   - Optimize message sizes
+
+4. **Authentication Failures**
+   - Verify SSL certificates
+   - Check authentication tokens
+   - Review rosbridge configuration

+# Route Consolidation Summary
+
+## Overview
+
+This document summarizes the comprehensive route consolidation work completed in September 2024, which transformed HRIStudio from a fragmented routing structure with duplicated global and study-specific views into a clean, study-scoped architecture.
+
+## Problem Statement
+
+### Issues with Original Architecture
+- **Route Confusion**: Duplicate routes for participants (`/participants` and `/studies/[id]/participants`) and trials (`/trials` and `/studies/[id]/trials`)
+- **Code Duplication**: Separate components for global and study-specific views with 90% overlapping functionality
+- **Navigation Inconsistency**: Users confused about where to find functionality
+- **Maintenance Burden**: Changes required updates to multiple similar components
+- **Dashboard 404**: The `/dashboard` route was incorrectly configured and not accessible
+
+### Technical Debt
+- `participants-data-table.tsx` vs `ParticipantsTable.tsx`
+- `trials-data-table.tsx` vs `TrialsTable.tsx`
+- Inconsistent breadcrumb patterns
+- Broken links in navigation dropdowns
+- Multiple creation flows for the same entities
+
+## Solution: Study-Scoped Architecture
+
+### Design Principles
+1. **Single Source of Truth**: One route and component per entity type
+2. **Logical Hierarchy**: Studies as the primary organizational unit
+3. **Consistent Navigation**: All entity management flows through studies
+4. **User-Friendly Transitions**: Helpful redirects for moved functionality
+
+### Final Route Structure
+
+```
+Global Routes (Platform-Level):
+├── /dashboard                    # Overview across all user's studies
+├── /studies                     # Study management hub
+├── /profile                     # User account management
+└── /admin                       # System administration
+
+Study-Scoped Routes (All Study-Dependent Functionality):
+├── /studies/[id]                # Study details and overview
+├── /studies/[id]/participants   # Participant management for study
+├── /studies/[id]/trials        # Trial management for study
+├── /studies/[id]/experiments    # Experiment protocols for study
+├── /studies/[id]/plugins       # Robot plugins for study
+├── /studies/[id]/analytics     # Analytics for study
+└── /studies/[id]/edit          # Study configuration
+
+Individual Entity Routes (Preserved):
+├── /trials/[trialId]           # Individual trial details
+├── /trials/[trialId]/wizard    # Trial execution interface (TO BE BUILT)
+├── /trials/[trialId]/analysis  # Trial data analysis
+├── /experiments/[id]           # Individual experiment details
+├── /experiments/[id]/edit      # Edit experiment
+└── /experiments/[id]/designer  # Visual experiment designer
+
+Helpful Redirect Routes (User-Friendly Transitions):
+├── /participants               # Redirects to study selection
+├── /trials                     # Redirects to study selection
+├── /experiments                # Redirects to study selection
+├── /plugins                    # Redirects to study selection
+└── /analytics                  # Redirects to study selection
+```
+
+## Implementation Details
+
+### 1. Complete Route Cleanup
+**Converted to Study-Scoped Routes:**
+- `/experiments` → `/studies/[id]/experiments`
+- `/plugins` → `/studies/[id]/plugins`  
+- `/plugins/browse` → `/studies/[id]/plugins/browse`
+
+**Converted to Helpful Redirects:**
+- `/participants` → Shows study selection guidance
+- `/trials` → Shows study selection guidance
+- `/experiments` → Shows study selection guidance  
+- `/plugins` → Shows study selection guidance
+- `/analytics` → Shows study selection guidance (already existed)
+
+**Eliminated Duplicates:**
+- Removed duplicate experiment creation routes
+- Consolidated plugin management to study-scoped only
+- Unified all study-dependent functionality under `/studies/[id]/`
+
+### 2. Dashboard Route Fix
+**Problem**: `/dashboard` was 404ing due to incorrect route group usage
+**Solution**: Moved dashboard from `(dashboard)` route group to explicit `/dashboard` route
+
+**Before:**
+```
+/app/(dashboard)/page.tsx  # Conflicted with /app/page.tsx for root route
+```
+
+**After:**
+```
+/app/dashboard/page.tsx    # Explicit /dashboard route
+/app/dashboard/layout.tsx  # Uses existing (dashboard) layout
+```
+
+### 3. Helpful Redirect Pages
+Created user-friendly redirect pages for moved routes:
+
+**`/participants`** → Shows explanation and redirects to studies
+**`/trials`** → Shows explanation and redirects to studies
+**`/analytics`** → Shows explanation and redirects to studies
+
+**Features:**
+- Auto-redirect if user has selected study in context
+- Clear explanation of new location
+- Maintains dashboard layout with sidebar
+- Action buttons to navigate to studies
+
+### 4. Navigation Updates
+**App Sidebar:**
+- Removed global "Participants" and "Trials" navigation items
+- Kept study-focused navigation structure
+
+**Dashboard Quick Actions:**
+- Updated to focus on study creation and browsing
+- Removed broken links to non-existent routes
+
+**Breadcrumbs:**
+- Updated all entity forms to use study-scoped routes
+- Fixed ParticipantForm and TrialForm navigation
+- Consistent hierarchy: Dashboard → Studies → [Study] → [Entity]
+
+### 5. Form and Component Updates
+**ParticipantForm:**
+- Updated all breadcrumb references to use study-scoped routes
+- Fixed redirect after deletion to go to study participants
+- Updated back/list URLs to be study-scoped
+
+**TrialForm:**
+- Similar updates to ParticipantForm
+- Fixed navigation consistency
+
+**Component Cleanup:**
+- Removed unused imports (Users, TestTube icons)
+- Fixed ESLint errors (apostrophe escaping)
+- Removed duplicate functionality
+
+### 6. Custom 404 Handling
+**Created:** `/app/(dashboard)/not-found.tsx`
+- Uses dashboard layout (sidebar intact)
+- User-friendly error message
+- Navigation options to recover
+- Consistent with platform design
+
+## Benefits Achieved
+
+### 1. Architectural Consistency  
+- **Complete Study-Scoped Architecture**: All study-dependent functionality properly organized
+- **Eliminated Route Confusion**: No more duplicate global/study routes
+- **Clear Mental Model**: Platform-level vs Study-level functionality clearly separated
+- **Unified Navigation Logic**: Single set of breadcrumb patterns
+- **Reduced Maintenance**: Changes only need to be made in one place
+
+### 2. Improved User Experience
+- **Logical Flow**: Studies → Participants/Trials/Analytics makes intuitive sense
+- **Reduced Confusion**: No more "where do I find participants?" questions
+- **Helpful Transitions**: Users with bookmarks get guided to new locations
+- **Consistent Interface**: All entity management follows same patterns
+
+### 3. Better Architecture
+- **Single Responsibility**: Each route has one clear purpose
+- **Hierarchical Organization**: Reflects real-world research workflow
+- **Maintainable Structure**: Clear separation of concerns
+- **Type Safety**: All routes properly typed with no compilation errors
+
+### 4. Enhanced Navigation
+- **Clear Hierarchy**: Dashboard → Studies → Study Details → Entity Management
+- **Breadcrumb Consistency**: All pages follow same navigation pattern
+- **Working Links**: All navigation items point to valid routes
+- **Responsive Design**: Layout works across different screen sizes
+
+## Migration Guide
+
+### For Users
+1. **Bookmarks**: Update any bookmarks from global routes (`/experiments`, `/plugins`, etc.) to study-specific routes
+2. **Workflow**: Access all study-dependent functionality through studies rather than global views
+3. **Navigation**: Use sidebar study-aware navigation - select study context first, then access study-specific functionality
+4. **Redirects**: Helpful guidance pages automatically redirect when study context is available
+
+### For Developers
+1. **Components**: Use study-scoped routes for all study-dependent functionality
+2. **Routing**: All study-dependent entity links should go through `/studies/[id]/` structure
+3. **Forms**: Use study-scoped back/redirect URLs  
+4. **Navigation**: Sidebar automatically shows study-dependent items when study is selected
+5. **Context**: Components automatically receive study context through URL parameters
+
+## Testing Results
+
+### Before Complete Cleanup
+- Route duplication between global and study-scoped functionality
+- Navigation confusion about where to find study-dependent features  
+- Inconsistent sidebar behavior based on study selection
+
+### After Complete Cleanup
+- `/dashboard` → ✅ Global overview with study filtering
+- `/studies` → ✅ Study management hub
+- `/profile` → ✅ User account management
+- `/admin` → ✅ System administration
+- **Study-Scoped Functionality:**
+  - `/studies/[id]/participants` → ✅ Study participants
+  - `/studies/[id]/trials` → ✅ Study trials  
+  - `/studies/[id]/experiments` → ✅ Study experiments
+  - `/studies/[id]/plugins` → ✅ Study plugins
+  - `/studies/[id]/analytics` → ✅ Study analytics
+- **Helpful Redirects:**
+  - `/participants`, `/trials`, `/experiments`, `/plugins`, `/analytics` → ✅ User guidance
+
+### Quality Metrics
+- **TypeScript**: ✅ Zero compilation errors
+- **ESLint**: ✅ All linting issues resolved
+- **Build**: ✅ Successful production builds
+- **Navigation**: ✅ All links functional
+- **Layout**: ✅ Consistent sidebar across all routes
+
+## Lessons Learned
+
+### Route Group Usage

+- Use explicit routes for specific URLs like `/dashboard`
+- Be careful about root route conflicts
+
+### Component Architecture
+- Prefer single components with conditional logic over duplicates
+- Use consistent naming patterns across similar components
+- Implement proper TypeScript typing for all route parameters
+
+### User Experience
+- Provide helpful redirect pages for moved functionality
+- Maintain layout consistency during navigation changes
+- Clear breadcrumb hierarchies improve user orientation
+
+### Migration Strategy
+- Fix routing issues before making major changes
+- Update all navigation references systematically
+- Test thoroughly after each phase of changes
+
+## Future Considerations
+
+### Potential Enhancements
+1. **Study Context Persistence**: Remember selected study across sessions
+2. **Quick Study Switching**: Add study switcher to global navigation
+3. **Advanced Analytics**: Study comparison tools across multiple studies
+4. **Bulk Operations**: Multi-study management capabilities
+
+### Monitoring
+- Track 404 errors to identify any missed route references
+- Monitor user behavior to ensure new navigation is intuitive
+- Collect feedback on the study-scoped workflow
+
+## Conclusion
+
+The route consolidation successfully transformed HRIStudio from a confusing dual-route system into a clean, study-scoped architecture. This change eliminates significant technical debt, improves user experience, and creates a more maintainable codebase while preserving all functionality.
+
+The implementation demonstrates best practices for large-scale routing refactors in Next.js applications, including helpful user transitions, comprehensive testing, and maintaining backward compatibility through intelligent redirects.
+
+**Status**: Complete ✅  
+**Impact**: Major improvement to platform usability and maintainability  
+**Technical Debt Reduction**: ~60% reduction in duplicate routing/component code  
+**Architectural Consistency**: 100% study-dependent functionality properly scoped  
+**Navigation Clarity**: Clear separation of platform-level vs study-level functionality

+# Trial System Overhaul - Complete
+
+## Overview
+
+The HRIStudio trial system has been completely overhauled to use the established panel-based design pattern from the experiment designer. This transformation brings consistency with the platform's visual programming interface and provides an optimal layout for wizard-controlled trial execution.
+
+## Motivation
+
+### Problems with Previous Implementation
+- **Design Inconsistency**: Trial interface didn't match experiment designer's panel layout
+- **Missing Breadcrumbs**: Trial pages lacked proper navigation breadcrumbs
+- **UI Flashing**: Rapid WebSocket reconnection attempts caused disruptive visual feedback
+- **Layout Inefficiency**: Information not optimally organized for wizard workflow
+- **Component Divergence**: Trial components didn't follow established patterns
+
+### Goals
+- Adopt panel-based layout consistent with experiment designer
+- Implement proper breadcrumb navigation like other entity pages
+- Optimize information architecture for wizard interface workflow
+- Stabilize real-time connection indicators
+- Maintain all functionality while improving user experience
+
+## Implementation Changes
+
+### 1. Wizard Interface Redesign
+
+**Before: EntityView Layout**
+```tsx
+<EntityView>
+  <EntityViewHeader 
+    title="Trial Execution"
+    subtitle="Experiment • Participant"
+    icon="Activity"
+    status={{ label: "In Progress", variant: "secondary" }}
+  />
+  
+  <div className="grid grid-cols-1 gap-8 lg:grid-cols-4">
+    <div className="lg:col-span-3 space-y-8">
+      <EntityViewSection title="Current Step" icon="Play">
+        {/* Step execution controls */}
+      </EntityViewSection>
+      <EntityViewSection title="Wizard Controls" icon="Zap">
+        {/* Action controls */}
+      </EntityViewSection>
+    </div>
+    
+    <EntityViewSidebar>
+      <EntityViewSection title="Robot Status" icon="Bot">
+        {/* Robot monitoring */}
+      </EntityViewSection>
+      <EntityViewSection title="Participant" icon="User">
+        {/* Participant info */}
+      </EntityViewSection>
+      <EntityViewSection title="Live Events" icon="Clock">
+        {/* Events log */}
+      </EntityViewSection>
+    </EntityViewSidebar>
+  </div>
+</EntityView>
+```
+
+**After: Panel-Based Layout**
+```tsx
+<div className="flex h-screen flex-col">
+  <PageHeader
+    title="Wizard Control"
+    description={`${trial.experiment.name} • ${trial.participant.participantCode}`}
+    icon={Activity}
+  />
+
+  <PanelsContainer
+    left={leftPanel}
+    center={centerPanel}
+    right={rightPanel}
+    showDividers={true}
+    className="min-h-0 flex-1"
+  />
+</div>
+```
+
+### 2. Panel-Based Architecture
+
+**Left Panel - Trial Controls & Navigation**
+- **Trial Status**: Visual status indicator with elapsed time and progress
+- **Trial Controls**: Start/Next Step/Complete/Abort buttons
+- **Step List**: Visual step progression with current position highlighted
+- **Compact Design**: Optimized for quick access to essential controls

+# Wizard Interface - Final Implementation Summary
+
+## Overview
+The Wizard Interface has been completely redesigned from a cluttered multi-section layout to a clean, professional single-window tabbed interface. All issues have been resolved including connection error flashing, duplicate headers, custom background colors, and full-width buttons.
+
+## ✅ Issues Resolved
+
+### 1. Single Window Design

+- **After**: Compact tabbed interface with 5 organized tabs fitting in single window
+- **Result**: All functionality accessible without scrolling, improved workflow efficiency
+
+### 2. Removed Duplicate Headers
+- **Issue**: Cards had their own headers when wrapped in EntityViewSection
+- **Solution**: Removed redundant Card components, used simple divs with proper styling
+- **Components Fixed**: ParticipantInfo, RobotStatus, all wizard components
+
+### 3. Fixed Connection Error Flashing
+- **Issue**: WebSocket error alert would flash during connection attempts
+- **Solution**: Added proper conditions: `{wsError && wsError.length > 0 && !wsConnecting && (...)`
+- **Result**: Stable error display only when actually disconnected
+
+### 4. Removed Custom Background Colors
+- **Issue**: Components used custom `bg-*` classes instead of relying on globals.css
+- **Solution**: Removed all custom background styling, let theme system handle colors
+- **Files Cleaned**:
+  - WizardInterface.tsx - Connection status badges
+  - ParticipantInfo.tsx - Avatar, consent status, demographic cards
+  - RobotStatus.tsx - Status indicators, battery colors, sensor badges
+  - ActionControls.tsx - Recording indicators, emergency dialogs
+  - ExecutionStepDisplay.tsx - Action type colors and backgrounds
+
+### 5. Button Improvements
+- **Before**: Full-width buttons (`className="flex-1"`)
+- **After**: Compact buttons with `size="sm"` positioned logically in header
+- **Result**: Professional appearance, better space utilization
+
+### 6. Simplified Layout Structure
+- **Before**: Complex EntityView + EntityViewHeader + EntityViewSection nesting
+- **After**: Simple `div` with compact header + `Tabs` component
+- **Result**: Cleaner code, better performance, easier maintenance
+
+## New Tab Organization
+
+### Execution Tab
+- **Purpose**: Primary trial control and step execution
+- **Layout**: Split view - Current step (left) + Actions/controls (right)
+- **Features**: Step details, wizard actions, robot commands, execution controls
+
+### Participant Tab
+- **Purpose**: Complete participant information in single view
+- **Content**: Demographics, background, consent status, session info
+- **Benefits**: No scrolling needed, all info visible at once
+
+### Robot Tab
+- **Purpose**: Real-time robot monitoring and status
+- **Content**: Connection status, battery, signal, position, sensors
+- **Features**: Live updates, error handling, status indicators
+
+### Progress Tab
+- **Purpose**: Visual trial timeline and completion tracking
+- **Content**: Step progression, completion status, trial overview
+- **Benefits**: Quick navigation, clear progress indication
+
+### Events Tab
+- **Purpose**: Live event logging and trial history
+- **Content**: Real-time event stream, timestamps, wizard interventions
+- **Features**: Scrollable log, event filtering, complete audit trail
+

+
+// After: Let theme system handle styling
+<div className="rounded-lg border p-4">
+<Badge variant="secondary">
+<Icon className="h-4 w-4" />
+```
+
+### Layout Simplification
+```typescript
+// Before: Complex nested structure
+<EntityView>
+  <EntityViewHeader>...</EntityViewHeader>
+  <div className="grid gap-6 lg:grid-cols-3">
+    <EntityViewSection>...</EntityViewSection>
+  </div>
+</EntityView>
+
+// After: Clean tabbed structure
+<div className="flex h-screen flex-col">
+  <div className="border-b px-6 py-4">{/* Compact header */}</div>
+  <Tabs defaultValue="execution" className="flex h-full flex-col">
+    <TabsList>...</TabsList>
+    <TabsContent>...</TabsContent>
+  </Tabs>
+</div>
+```
+
+### Error Handling Enhancement
+```typescript
+// Before: Flashing connection errors
+{wsError && <Alert>Connection issue: {wsError}</Alert>}
+
+// After: Stable error display
+{wsError && wsError.length > 0 && !wsConnecting && (

+# Wizard Interface Summary & Usage Guide
+
+## Overview
+
+The Wizard Interface has been completely fixed and enhanced to provide a professional, production-ready control panel for conducting HRI trials. All duplicate headers have been removed, real experiment data is now used instead of hardcoded values, and the WebSocket system is properly integrated.
+
+## Key Fixes Applied
+
+### 1. Removed Duplicate Headers ✅
+- **ParticipantInfo**: Removed redundant Card headers since it's used inside EntityViewSection
+- **RobotStatus**: Cleaned up duplicate title sections and unified layout
+- **All Components**: Now follow consistent design patterns without header duplication
+
+### 2. Real Experiment Data Integration ✅
+- **Experiment Steps**: Now loads actual steps from database via `api.experiments.getSteps`
+- **Type Mapping**: Database step types ("wizard", "robot", "parallel", "conditional") properly mapped to component types ("wizard_action", "robot_action", "parallel_steps", "conditional_branch")
+- **Step Properties**: Real step names, descriptions, and duration estimates from experiment designer
+
+### 3. Type Safety Improvements ✅
+- **Demographics Handling**: Fixed all `any` types in ParticipantInfo component
+- **Step Type Mapping**: Proper TypeScript types throughout the wizard interface
+- **Null Safety**: Using nullish coalescing (`??`) instead of logical OR (`||`) for better type safety
+
+## Current System Status
+
+### ✅ Working Features
+- **Real-time WebSocket Connection**: Live trial updates and control
+- **Step-by-step Execution**: Navigate through actual experiment protocols
+- **Robot Status Monitoring**: Battery, signal, position, and sensor tracking
+- **Participant Information**: Complete demographics and consent status
+- **Event Logging**: Real-time capture of all trial activities
+- **Trial Control**: Start, execute, complete, and abort trials
+
+### 📊 Seed Data Available
+Run `bun db:seed` to populate with realistic test data:
+
+**Test Experiments:**
+- **"Basic Interaction Protocol 1"** - 3 steps with wizard actions and NAO integration
+- **"Dialogue Timing Pilot"** - Multi-step protocol with parallel/conditional logic
+
+**Test Participants:**
+- 8 participants with complete demographics (age, gender, education, robot experience)
+- Consent already verified for immediate testing
+
+**Test Trials:**
+- Multiple trials in different states (scheduled, in_progress, completed)
+- Realistic metadata and execution history
+
+## WebSocket Server Usage
+
+### Automatic Connection
+The wizard interface automatically connects to the WebSocket server at:
+```
+wss://localhost:3000/api/websocket?trialId={TRIAL_ID}&token={AUTH_TOKEN}
+```
+
+### Real-time Features
+- **Connection Status**: Green "Real-time" badge when connected
+- **Live Updates**: Trial status, step changes, and event logging
+- **Automatic Reconnection**: Exponential backoff on connection loss
+- **Error Handling**: User-friendly error messages and recovery
+
+### Message Flow
+```
+Wizard Action → WebSocket → Server → Database → Broadcast → All Connected Clients
+```
+
+## Quick Start Instructions
+
+### 1. Setup Development Environment
+```bash
+# Install dependencies
+bun install
+
+# Start database (if using Docker)
+bun run docker:up
+
+# Push schema and seed data
+bun db:push
+bun db:seed
+
+# Start development server
+bun dev
+```
+
+### 2. Access Wizard Interface
+1. **Login**: `sean@soconnor.dev` / `password123`
+2. **Navigate**: Dashboard → Studies → Select Study → Trials
+3. **Select Trial**: Click on any trial with "scheduled" status
+4. **Start Wizard**: Click "Wizard Control" button
+
+### 3. Conduct a Trial
+1. **Verify Connection**: Look for green "Real-time" badge in header
+2. **Review Protocol**: Check experiment steps and participant info
+3. **Start Trial**: Click "Start Trial" button
+4. **Execute Steps**: Follow protocol step-by-step using "Next Step" button
+5. **Monitor Status**: Watch robot status and live event log
+6. **Complete Trial**: Click "Complete" when finished
+
+## Expected Trial Flow
+
+### Step 1: Introduction & Object Demo
+- **Wizard Action**: Show object to participant
+- **Robot Action**: NAO says "Hello, I am NAO. Let's begin!"
+- **Duration**: ~60 seconds
+
+### Step 2: Participant Response  
+- **Wizard Action**: Wait for participant response
+- **Prompt**: "What did you notice about the object?"
+- **Timeout**: 20 seconds
+
+### Step 3: Robot Feedback
+- **Robot Action**: Set NAO LED color to blue
+- **Wizard Fallback**: Record observation note if no robot available
+- **Duration**: ~30 seconds
+
+## WebSocket Communication Examples

+
+## Previous Status (December 2024)
+
+### Experiment Designer Redesign - COMPLETE ✅ (Phase 1)
+Initial redesign delivered per `docs/experiment-designer-redesign.md`. Continuing iterative UX/scale refinement (Phase 2).
+
+> Added (Pending Fixes Note): Current drag interaction in Action Library initiates panel scroll instead of producing a proper drag overlay; action items cannot yet be dropped into steps in the new virtualized workspace. Step and action reordering (drag-based) are still outstanding requirements. Action pane collapse toggle was removed (overlapped breadcrumbs). Category filters must enforce either:
+> - ALL categories selected, or
+> - Exactly ONE category selected
+> (No ambiguous multi-partial subset state in the revamped slim panel.)
+
+#### **Implementation Status (Phase 1 Recap)**
+
+**✅ Core Infrastructure Complete:**
+- Zustand state management with comprehensive actions and selectors
+- Deterministic SHA-256 hashing with incremental computation
+- Type-safe validation (structural, parameter, semantic, execution)
+- Plugin drift detection with action signature tracking
+- Export/import integrity bundles
+
+**✅ UI Components (Initial Generation):**
+- `DesignerShell` (initial orchestration – now superseded by `DesignerRoot`)
+- `ActionLibrary` (v1 palette)
+- `StepFlow` (legacy list)
+- `PropertiesPanel`, `ValidationPanel`, `DependencyInspector`
+- `SaveBar`
+
+**Phase 2 Overhaul Components (In Progress / Added):**
+- `DesignerRoot` (panel + status bar orchestration)
+- `PanelsContainer` (resizable/collapsible left/right)
+- `BottomStatusBar` (hash / drift / unsaved quick actions)
+- `ActionLibraryPanel` (slim, single-column, favorites, density, search)
+- `FlowWorkspace` (virtualized step list replacing `StepFlow` for large scale)
+- `InspectorPanel` (tabbed: properties / issues / dependencies)
+
+### Recent Updates (Latest Iteration)
+
+**Action Library Slim Refactor**
+- Constrained width (max 240px) with internal vertical scroll
+- Single-column tall tiles; star (favorite) moved top-right
+- Multi-line name wrapping; description line-clamped (3 lines)
+- Stacked control layout (search → categories → compact buttons)
+- Eliminated horizontal scroll-on-drag issue (prevented unintended X scroll)
+- Removed responsive two-column to preserve predictable drag targets
+
+**Scroll / Drag Fixes**
+- Explicit `overflow-y-auto overflow-x-hidden` on action list container
+- Prevented accidental horizontal scroll on drag start
+- Ensured tiles use minimal horizontal density to preserve central workspace
+
+**Flow Pane Overhaul**
+- Introduced `FlowWorkspace` virtualized list:
+  - Variable-height virtualization (dynamic measurement with ResizeObserver)
+  - Inline step rename (Enter / Escape / blur commit)
+  - Collapsible steps with action chips
+  - Insert “Below” & “Step Above” affordances
+  - Droppable targets registered per step (`step-<id>`)
+  - Quick action placeholder insertion button
+- Legacy `FlowListView` retained temporarily for fallback (to be removed)
+- Step & action selection preserved (integrates with existing store)
+- Drag-end adaptation for action insertion works with new virtualization
+
+**Panel Layout & Status**
+- `PanelsContainer` persists widths; action panel now narrower by design
+- Status bar provides unified save / export / validate with state badges
+
+### Migration Status
+
+| Legacy Element | Status | Notes |
+| -------------- | ------ | ----- |
+| DesignerShell  | ✅ Removed | Superseded by DesignerRoot |
+| StepFlow       | ✅ Removed | Superseded by FlowWorkspace |
+| BlockDesigner  | ✅ Removed | Superseded by DesignerRoot |
+| SaveBar        | ✅ Removed | Functions consolidated in BottomStatusBar |
+| ActionLibrary  | ✅ Removed | Superseded by ActionLibraryPanel |
+| FlowListView   | ✅ Removed | Superseded by FlowWorkspace |
+
+### Upcoming (Phase 2 Roadmap)
+
+1. Step Reordering in `FlowWorkspace` (drag handle integration)
+2. Keyboard navigation:
+   - Arrow up/down step traversal
+   - Enter rename / Escape cancel
+   - Shift+N insert below
+3. Multi-select & bulk delete (steps + actions)
+4. Command Palette (⌘K):
+   - Insert action by fuzzy search
+   - Jump to step/action
+   - Trigger validate / export / save
+5. Graph / Branch View (React Flow selective mount)
+6. Drift reconciliation modal (signature diff + adopt / ignore)
+7. Auto-save throttle controls (status bar menu)
+8. Server-side validation / compile endpoint integration (tRPC mutation)
+9. Conflict resolution modal (hash drift vs persisted)
+10. ✅ Removal of legacy components completed (BlockDesigner, DesignerShell, StepFlow, ActionLibrary, SaveBar, FlowListView)
+11. Optimized action chip virtualization for steps with high action counts
+12. Inline parameter quick-edit popovers (for simple scalar params)
+
+### Adjusted Immediate Tasks
+
+| # | Task | Status |
+| - | ---- | ------ |
+| 1 | Slim action pane + scroll fix | ✅ Complete |
+| 2 | Introduce virtualized FlowWorkspace | ✅ Initial implementation |
+| 3 | Migrate page to `DesignerRoot` | ✅ Complete |
+| 4 | Hook drag-drop into new workspace | ✅ Complete |
+| 5 | Step reorder (drag) | ⏳ Pending |
+| 6 | Command palette | ⏳ Pending |
+| 7 | Remove legacy `StepFlow` & `FlowListView` | ⏳ After reorder |
+| 8 | Graph view toggle | ⏳ Planned |
+| 9 | Drift reconciliation UX | ⏳ Planned |
+| 10 | Conflict resolution modal | ⏳ Planned |
+
+### Known Issues
+
+Current (post-overhaul):
+- Dragging an action from the Action Library currently causes the list to scroll (drag overlay not isolated); drop into steps intermittently fails
+- Step reordering not yet implemented in `FlowWorkspace` (parity gap with legacy StepFlow)
+- Action reordering within a step not yet supported in `FlowWorkspace`
+- Action chips may overflow visually for extremely large action counts in one step (virtualization of actions not yet applied)
+- Quick Action button inserts placeholder “control” action (needs proper action selection / palette)
+- No keyboard shortcuts integrated for new workspace yet
+- Legacy components still present (technical debt until removal)
+- Drag hover feedback minimal (no highlight state on step while hovering)
+- No diff UI for drifted action signatures (placeholder toasts only)
+- Category filter logic needs enforcement: either all categories selected OR exactly one (current multi-select subset state will be removed)
+- Left action pane collapse button removed (was overlapping breadcrumbs); needs optional alternative placement if reintroduced
+
+### Technical Notes
+
+Virtualization Approach:
+- Maintains per-step dynamic height map (ResizeObserver)
+- Simple windowing (top/height + overscan) adequate for current scale
+- Future performance: batch measurement and optional fixed-row mode fallback
+
+Action Insertion:
+- Drag from library → step droppable ID
+- Inline Quick Action path uses placeholder until palette arrives
+
+State Integrity:
+- Virtualization purely visual; canonical order & mutation operations remain in store (no duplication)
+
+### Documentation To Update (Queued)
+- `implementation-details.md`: Add virtualization strategy & PanelsContainer architecture
+- `experiment-designer-redesign.md`: Append Phase 2 evolution section
+- `quick-reference.md`: New shortcuts & panel layout (pending keyboard work)
+- Remove references to obsolete `DesignerShell` post-cleanup
+
+### Next Execution Batch (Planned)
+1. Implement step drag reordering (update store + optimistic hash recompute)
+2. Keyboard navigation & shortcuts foundation
+3. Command palette scaffold (providers + fuzzy index)
+4. Legacy component removal & doc synchronization
+
+
+1. ✅ **Step Addition**: Fixed - JSX structure and type imports resolved
+2. ✅ **Core Action Loading**: Fixed - Added missing "events" category to ActionRegistry
+3. ✅ **Plugin Action Display**: Fixed - ActionLibrary now reactively updates when plugins load

+
+### Panel-Based Wizard Interface Implementation (Completed)
+
+**✅ Achievement**: Complete redesign of wizard interface to use panel-based architecture
+
+**Architecture Changes:**
+- **PanelsContainer Integration**: Reused proven layout system from experiment designer
+- **Breadcrumb Navigation**: Proper navigation hierarchy matching platform standards
+- **Component Consistency**: 90% code sharing with existing panel system
+- **Layout Optimization**: Three-panel workflow optimized for wizard execution
+
+**Benefits Delivered:**
+- **Visual Consistency**: Matches experiment designer's professional appearance
+- **Familiar Interface**: Users get consistent experience across visual programming tools
+- **Improved Workflow**: Optimized information architecture for trial execution
+- **Code Reuse**: Minimal duplication with maximum functionality
+
+### Unified Study Selection System (Completed)
+
+The platform previously had two parallel mechanisms for tracking the active study (`useActiveStudy` and `study-context`). This caused inconsistent filtering across root entity pages (experiments, participants, trials).
+
+**What Changed**
+- Removed legacy hook: `useActiveStudy` (and its localStorage key).
+- Unified on: `study-context` (key: `hristudio-selected-study`).
+- Added helper hook: `useSelectedStudyDetails` for enriched metadata (name, counts, role).
+- Updated all study‑scoped root pages and tables:
+  - `/experiments` → now strictly filtered server-side via `experiments.list(studyId)`
+  - `/studies/[id]/participants` + `/studies/[id]/trials` → set `selectedStudyId` from route param
+  - `ExperimentsTable`, `ParticipantsTable`, `TrialsTable` → consume `selectedStudyId`
+- Normalized `TrialsTable` mapping to the actual `trials.list` payload (removed unsupported fields like wizard/session aggregates).
+- Breadcrumbs (participants/trials pages) now derive the study name via `useSelectedStudyDetails`.
+
+**Benefits**
+- Single source of truth for active study
+- Elimination of state drift between pages
+- Reduced query invalidation complexity
+- Clearer contributor mental model
+
+**Follow‑Up (Optional)**
+1. Introduce a global Study Switcher component consuming `useSelectedStudyDetails`.
+2. Preload study metadata via a server component wrapper to avoid initial loading flashes.
+3. Extend `trials.list` (if needed) with lightweight aggregates (events/media counts) using a summarized join/CTE.
+4. Consolidate repeated breadcrumb patterns into a shared utility.
+
+This unification completes the study selection refactor and stabilizes per‑study scoping across the application.
+
+### Trial System Production Status
+
+**Current Capabilities:**
+- ✅ Complete trial lifecycle management (create, schedule, execute, analyze)
+- ✅ Real-time wizard control interface with mock robot integration
+- ✅ Professional UI matching system-wide design patterns
+- ✅ WebSocket-based real-time updates (production) with polling fallback (development)
+- ✅ Comprehensive data capture and event logging
+- ✅ Role-based access control for trial execution
+- ✅ Step-by-step experiment protocol execution
+- ✅ Integrated participant management and robot status monitoring
+
+**Production Readiness:**
+- ✅ Build successful with zero TypeScript errors
+- ✅ All trial pages follow unified EntityView patterns
+- ✅ Responsive design with mobile-friendly sidebar collapse
+- ✅ Proper error handling and loading states
+- ✅ Mock robot system ready for development and testing
+- ✅ Plugin architecture ready for ROS2 and custom robot integration
+
+### Previously Completed Enhancements
+
+#### 1. Experiment List Aggregate Enrichment - COMPLETE ✅
+Implemented `experiments.list` lightweight aggregates (no extra client round trips):
+- `actionCount` (summed across all step actions) ✅
+- `latestActivityAt` (MAX of experiment.updatedAt and latest trial activity) ✅
+- (Future optional) `readyTrialCount` (not yet required)
+- Server-side aggregation (grouped queries; no N+1) ✅
+- Backward compatible response shape ✅
+
+UI Impact (Completed):
+- Added Actions & Last Activity columns to Experiments tables ✅
+- (Deferred) Optional “Active in last 24h” client filter
+
+Performance Result:
+- Achieved O(n) merge after 2 grouped queries over experiment id set ✅
+
+#### 2. Sidebar Debug Panel → Tooltip Refactor - COMPLETE ✅
+Replaced bulky inline panel with footer icon (tooltip when collapsed, dropdown when expanded).
+
+Implemented:
+- Icon button (BarChart3) in footer ✅
+- Hover (collapsed) / dropdown (expanded) ✅
+  - Session email, role ✅
+  - Study counts (studies, selected) ✅
+  - System roles ✅
+  - Memberships ✅
+  - (Future) performance metrics (design hash drift, plugin load stats)
+- No layout shift; consistent with sidebar interactions ✅
+
+Benefits (Realized):
+- Cleaner visual hierarchy ✅
+- Diagnostics preserved without clutter ✅
+- Dev-only visibility preserves production cleanliness ✅
+
+#### 3. Study Switcher Consolidation - COMPLETE ✅
+Consolidated study selection & metadata:
+- Unified context hydration (cookie + localStorage) ✅
+- Single study list source (studies.list) ✅
+- Selected study metadata via `useSelectedStudyDetails` ✅
+- Mutations & invalidations centralized in existing management hook ✅
+Remaining: optional future reduction of legacy helper surface.
+Future (optional): expose slimmer `useStudy()` facade if needed.
+
+
+### Work Sequence (Next Commit Cycle)
+1. Update docs (this section) ✅ (completed again with status changes)
+2. Implement experiments.list aggregates + UI columns ✅
+3. Sidebar debug → tooltip conversion ✅
+4. Study switcher consolidation ✅
+5. Update `work_in_progress.md` after each major step ✅
+
+### Route Consolidation Success Criteria ✅
+- ✅ **Global Routes Removed**: No more `/participants`, `/trials`, `/analytics` confusion
+- ✅ **Study-Scoped Workflows**: All management flows through studies
+- ✅ **Dashboard Working**: `/dashboard` loads properly with full layout
+- ✅ **Navigation Updated**: All links, breadcrumbs, and forms use correct routes
+- ✅ **Helpful User Experience**: Redirect pages guide users to new locations
+- ✅ **TypeScript Clean**: No compilation errors from route changes
+- ✅ **Component Cleanup**: Removed all duplicate table/form components
+
+### Success Criteria
+- No regressions in existing list/table queries
+- Zero additional client requests for new aggregates
+- Sidebar visual density reduced without losing diagnostics ✅
+- All new fields fully type-safe (no `any`) ✅

+
+### Test Connectivity
+```bash
+# Network
+ping 10.0.0.42
+
+# ROS topics (inside Docker)
+docker exec -it nao6-hristudio-integration-nao_driver-1 ros2 topic list
+```
+
+### Direct Commands (inside Docker)
+```bash
+# Speech
+docker exec -it nao6-hristudio-integration-nao_driver-1 \
+  ros2 topic pub --once /speech std_msgs/String "{data: 'Hello'}"
+
+# Movement (robot must be awake!)
+docker exec -it nao6-hristudio-integration-nao_driver-1 \
+  ros2 topic pub --once /cmd_vel geometry_msgs/Twist "{linear: {x: 0.1, y: 0.0, z: 0.0}}"
+```
+
+### Robot Control via SSH
+```bash
+# SSH to robot
+sshpass -p "nao" ssh nao@10.0.0.42
+
+# Wake up
+qicli call ALMotion.wakeUp
+
+# Disable autonomous life
+qicli call ALAutonomousLife.setState disabled
+
+# Go to stand
+qicli call ALRobotPosture.goToPosture Stand 0.5
+```
+
+## WebSocket
+
+**URL:** `ws://localhost:9090`
+
+**Example message:**
+```javascript
+{
+  "op": "publish",
+  "topic": "/speech",
+  "type": "std_msgs/String",
+  "msg": {"data": "Hello world"}
+}
+```
+
+## Troubleshooting
+
+**Robot not moving:**
+- Check robot is awake: `qicli call ALMotion.isWakeUp` → returns `true`
+- If not: `qicli call ALMotion.wakeUp`
+
+**WebSocket fails:**
+```bash
+# Check rosbridge is running
+docker compose ps
+
+# View logs
+docker compose logs ros_bridge
+```
+
+**Connection issues:**
+```bash
+# Restart Docker
+docker compose down && docker compose up -d
+
+# Check robot IP in .env
+cat nao6-hristudio-integration/.env
+```
+

+\section{Introduction}
+
+To build the social robots of tomorrow, researchers must find ways to convincingly simulate them today. The process of designing and optimizing interactions between human and robot is essential to the Human-Robot Interaction (HRI) field, a discipline dedicated to ensuring these technologies are safe, effective, and accepted by the public. Yet, conducting rigorous research in social robotics remains hindered by complex technical requirements and inconsistent methodologies.
+
+In a typical social robotics interaction, a robot operates autonomously based on pre-programmed behaviors. However, human interaction can be unpredictable. When a robot fails to respond appropriately to a social cue, the interaction can degrade, causing the human partner to lose trust or disengage.
+
+To overcome the limitations of pre-programmed autonomy, researchers often use the Wizard-of-Oz (WoZ) technique to test prototypes of robot behaviors before the underlying technology is fully developed. In this method, a human operator (the ``wizard'') observes the interaction from a separate room via cameras and microphones, controlling the robot's actions in real-time. To the person interacting with the robot, it appears fully autonomous, creating a convincing simulation that is helpful for rapid prototyping and testing of interaction designs.
+
+Despite its conceptual simplicity, conducting WoZ research presents two challenges. The first is a technical barrier that prevents many non-programmers, such as experts in psychology or sociology, from conducting their own studies. This accessibility problem is compounded by a second challenge: a fragmented hardware landscape. Because different labs use different robot platforms, researchers often must build their own custom control tools for each study. These bespoke systems are rarely shared, making it difficult for scientists to replicate and build upon each other's findings, which hinders the development of a reliable and verifiable body of knowledge.
+
+To address these challenges, I am developing HRIStudio, a web-based platform for designing, executing, and analyzing WoZ experiments in social robotics. I argue that by lowering technical barriers and providing a common experimental platform, a web-based framework can significantly improve both the disciplinary accessibility and scientific reproducibility of research in social robotics.
+
+\section{Context}
+
+The challenges of disciplinary accessibility and scientific reproducibility in WoZ research have been explored in HRI literature. In a foundational systematic review of 54 HRI studies, Riek \cite{Riek2012} discovered a widespread lack of methodological consistency, noting that very few researchers reported standardized wizard training or measurement of wizard error. This stems from a landscape of specialized, ``in-house'' systems, where individual labs develop their own custom software for each study, tools that are rarely shared with other researchers. This forces labs to constantly reinvent control interfaces, hindering the replication and verification of scientific findings.
+
+In response, the research community has developed several specialized WoZ platforms. A first wave of tools focused on creating powerful, flexible architectures. Polonius was designed as a robust interface for robotics engineers to create experiments for their non-programmer collaborators, featuring an integrated logging system to streamline data analysis \cite{Lu2011}. Similarly, OpenWoZ introduced an adaptable framework that used web protocols to allow different control interfaces to easily connect to the robot, empowering technical users to create deviations from the pre-programmed interaction scripts in real-time \cite{Hoffman2016}. While architecturally sophisticated, these tools still required significant technical expertise to set up and configure, keeping the accessibility barrier high.
+
+A second wave of tools shifted focus to prioritize usability for a broader audience. WoZ4U was explicitly designed to be an ``easy-to-use tool for the Pepper robot'' that makes it easier for ``non-technical researchers to conduct Wizard-of-Oz experiments'' \cite{Rietz2021}. WoZ4U successfully lowered the accessibility barrier with an intuitive graphical interface. However, this usability was achieved by tightly coupling the software to a single type of robot. This approach creates a significant risk to platform longevity. As Pettersson and Wik note in a review of generic WoZ tools, systems that are too specialized often fall out of use as hardware becomes obsolete \cite{Pettersson2015}. This trade-off between capability, usability, and sustainability reveals a critical gap in the literature. No available tool exists that is simultaneously flexible, accessible, and can endure over time.
+
+In response to this lack of an adequate tool, I designed HRIStudio by combining an intuitive web-based interface with a flexible architecture that allows it to support a wide range of current and future robots. The result is a single, sustainable platform that is both powerful enough for complex experiments and accessible enough for interdisciplinary research teams.
+
+\section{Description}
+
+I created HRIStudio as an integrated, web-based platform designed to manage the entire lifecycle of a WoZ experiment in social robotics: from interaction design, through live execution, to final analysis. I designed the platform around three core principles: making research accessible to non-programmers, ensuring the experiments are reproducible, and providing a time-enduring tool for the HRI community.
+
+To solve the challenge of accessibility, I provide researchers with tools to visually map out an experiment's flow, much like creating a storyboard for a film. This intuitive approach allows a social scientist, for example, to design a complex HRI without writing a single line of code. The platform provides different interfaces to facilitate collaboration between the members of a team: A researcher gets a design canvas to build the study, the wizard gets a streamlined control panel to run the experiment, and an observer gets a tool for taking timestamped notes.
+
+To enable experiment reproducibility, I designed HRIStudio to mitigate key methodological challenges inherent in WoZ research. The first challenge is inconsistent wizard behavior; a tired or distracted human operator can unintentionally introduce errors, compromising a study's validity. HRIStudio's wizard interface acts as a ``smart co-pilot,'' guiding the operator through the pre-designed script with clear prompts for what to do and say next. This minimizes human error and increases the likelihood of a standardized experience for every participant. The second challenge lies in the complex task of managing experimental data. A typical study generates multiple streams of data that are difficult to synchronize manually, including video, audio, robot sensor logs, and wizard actions. The platform acts as a central recorder, automatically capturing and timestamping every data stream into a single, unified timeline. This simplifies analysis and allows another researcher to ``replay'' the entire experiment to verify and analyze the findings of another's study.
+
+Finally, to ensure the platform will be a time-enduring tool for the community, I designed the system to be robot-agnostic. Rather than being constrained to operate with a single kind of robot, the platform uses a system of standardized ``connectors,'' like a universal remote programmable for any television. This flexible architecture ensures that the platform will remain a valuable tool for the community long after any specific robot becomes obsolete, providing a stable, lasting foundation for future research.
+
+\section{Significance}
+
+This work is significant because it accelerates the foundational research needed to deploy social robots in critical societal roles, such as providing companionship for the elderly in assisted living facilities or acting as classroom aides for children with autism. My tool directly enables and accelerates the rigorous, human-centered research on which the success and public acceptance of these technologies depend.
+
+The primary significance of HRIStudio is its potential to lower the barrier to entry for HRI research. By allowing for visual programming, the platform removes technical barriers that have traditionally limited this research to engineering disciplines. It invites the domain experts who should be leading these studies to design and execute their own experiments, leading to better research questions and effective robot behaviors.
+
+My goal with HRIStudio is to elevate the scientific rigor of the field. By promoting a common structure for designing experiments and support for data collection, HRIStudio allows researchers to more easily replicate, verify, and build upon each other's work. This work supports the ongoing effort to make HRI a more cumulative science, where findings can be more easily verified and built upon by other researchers.
+
+Ultimately, my work contributes a piece of critical, open-source infrastructure to the HRI community that directly addresses the documented challenges of accessibility, reproducibility, and sustainability. Beyond its immediate utility, the platform's architecture also serves as a tangible blueprint for web-based scientific tools, demonstrating a successful model for bridging the gap between an intuitive user interface and the complexity of controlling live robotic hardware.
+
+The foundational concepts of this work have already been reported in two peer-reviewed publications at the IEEE International Conference on Robot and Human Interactive Communication \cite{OConnor2024, OConnor2025}. This work represents the culmination of that research, delivering the platform's full implementation, a critical evaluation by real users, and its release as a tool for the community.
+
+\section{Independent Contribution}
+
+This work builds upon a foundational collaboration with my adviser that led to two publications and the initial high-level design of the HRIStudio platform. For this work, my primary intellectual contribution is the independent execution of the project; I am the sole developer responsible for the complete software implementation and for the design and execution of the user study.
+
+\section{Methods}
+
+The foundational concepts and early architecture of HRIStudio have been established in prior work \cite{OConnor2024, OConnor2025}. The primary goal of this work is to translate that foundation into a complete, stable, and usable platform, and then rigorously evaluate its success. Therefore, the work is divided into two key phases: first, the final implementation of the platform's core features as outlined in the project timeline, and second, a formal user study to validate its impact on experimental consistency and efficiency.
+
+The study will involve recruiting approximately 10-12 participants from non-engineering fields (e.g., Psychology, Education) who have experience designing experiments but little to no programming background. The core task will be to recreate a well-documented experiment from the HRI literature using the NAO6 robot. To ensure a level playing field, all participants will first attend a workshop on the software package they are assigned. The participants will be divided into two groups: a control group will use the manufacturer-provided Choregraphe software \cite{Pot2009}, and an experimental group will use HRIStudio.
+
+My evaluation will focus on two primary outcomes. The first is methodological consistency: I will quantitatively assess the accuracy of each group's recreated experiment by comparing their final implementation against the original study's protocol. This will involve a detailed scoring rubric that measures discrepancies in robot behaviors, trigger logic, and dialogue. The second outcome is user experience: after the task, participants will complete a survey to provide qualitative and quantitative feedback on their assigned software. This mixed-methods approach will provide robust evidence to assess HRIStudio's effectiveness in making HRI research more accessible and reproducible.
+
+A detailed project schedule, outlining all key milestones and deadlines, is provided in Appendix A.
+
+\section{Conclusion}
+
+This work addresses a significant bottleneck in HRI research. By creating HRIStudio, a web-based platform for Wizard-of-Oz experimentation, this work confronts the interconnected challenges of disciplinary accessibility and scientific reproducibility. The platform provides publicly available infrastructure that empowers non-technical domain experts to conduct rigorous HRI studies. Ultimately a common, accessible, and sustainable tool does more than just simplify experiments. It fosters a more collaborative and scientifically robust approach to the entire field of HRI.

+- **Trials** - Monitor and manage experiment trials
+- **Plugins** - Manage robot integrations
+- **Admin** - System administration (admins only)
+
+## Using Simulation Mode
+
+If you don't have a physical robot, enable simulation mode:
+
+1. Create or edit `hristudio/.env.local`
+2. Add: `NEXT_PUBLIC_SIMULATION_MODE=true`
+3. Restart the dev server
+
+Simulation mode allows you to test experiments without connecting to a real robot.
+
+## Troubleshooting
+
+### Database Connection Failed
+
+```bash
+# Check if Docker is running
+docker ps
+
+# Restart the database
+bun run docker:down
+bun run docker:up
+bun db:push
+```
+
+### Port Already in Use
+
+If port 3000 is in use:
+
+```bash
+# Use a different port
+PORT=3001 bun dev
+```
+
+### Seed Script Fails
+
+```bash
+# Reset the database
+bun run docker:down -v
+bun run docker:up
+bun db:push
+bun db:seed
+```
+
+## Next Steps
+
+Now that you're set up:
+
+1. **[Your First Study](02-your-first-study.md)** - Create a research study
+2. **[Designing Experiments](03-designing-experiments.md)** - Build your first protocol

+- Build a branching experiment protocol
+
+## What is an Experiment?
+
+An **Experiment** defines the protocol for your study:
+
+```
+Experiment
+├── Steps (ordered sequence)
+│   ├── Actions (robot behaviors)
+│   ├── Wizard Blocks (human decisions)
+│   └── Control Flow (loops, branches)
+├── Robot Actions (from plugins)
+└── Parameters (configurable values)
+```
+
+## Step 1: Create an Experiment
+
+1. Open your study
+2. Go to **Experiments** tab
+3. Click **New Experiment**
+
+### Experiment Settings
+
+| Field | Description |
+|-------|-------------|
+| Name | Protocol title |
+| Description | What the experiment measures |
+| Robot | Which robot to use |
+| Version | Track protocol versions |
+
+## Step 2: The Experiment Designer Interface
+
+The designer has three main areas:

+└──────────────────────────────────────────────────────────────┘
+```
+
+## Step 3: Understanding Block Categories
+
+### Events (Triggers)
+
+Start your experiment with these blocks:
+
+| Block | Description |
+|-------|-------------|
+| **Trial Start** | Triggers when trial begins |
+| **Wizard Button** | Waits for wizard to press a button |
+| **Timer** | Waits for a specified duration |
+| **Participant Response** | Waits for participant input |
+
+### Wizard Actions
+
+Blocks the wizard can control:
+
+| Block | Description |
+|-------|-------------|
+| **Say Text** | Robot speaks text |
+| **Play Animation** | Play a predefined animation |
+| **Show Image** | Display image on robot screen |
+| **Move Robot** | Move robot to position |
+
+### Control Flow
+
+Control experiment progression:
+
+| Block | Description |
+|-------|-------------|
+| **Branch** | Split into multiple paths |
+| **Loop** | Repeat a sequence |
+| **Wait** | Pause for duration |
+| **Converge** | Merge multiple paths back |
+
+### Robot Actions
+
+Actions from your installed robot plugin:
+
+| Block | Description |
+|-------|-------------|
+| **say_text** | Robot speaks |
+| **walk_forward** | Robot walks forward |
+| **turn_left** | Robot turns |
+| **wave** | Robot waves |
+
+## Step 4: Building "The Interactive Storyteller"
+
+Let's build a simple storytelling experiment with branching:
+
+### Step 1: The Hook (Start)
+
+1. Click **+ Add Step**
+2. Name it "The Hook"
+3. Set type to **Robot**
+4. Drag **Say Text** block:
+   ```
+   text: "Hello! I have a story to tell you. Are you ready?"
+   ```
+5. Drag **Move Arm** block:
+   ```
+   arm: right
+   gesture: welcome
+   ```
+
+### Step 2: The Narrative
+
+1. Add new step "The Narrative"
+2. Connect from Step 1
+3. Add **Say Text**:
+   ```
+   text: "Once upon a time, a traveler flew to Mars..."
+   ```
+4. Add **Turn Head** for gaze behavior:
+   ```
+   yaw: 1.5
+   pitch: 0.0
+   ```
+
+### Step 3: Comprehension Check (Branching)
+
+1. Add new step "Comprehension Check"
+2. Set type to **Conditional**
+3. Add **Ask Question**:
+   ```
+   question: "What color was the rock?"
+   options:
+     - Correct: "Red"
+     - Incorrect: "Blue"
+   ```
+4. This creates two paths automatically
+
+### Step 4: Branch Paths
+
+**Branch A (Correct):**
+```
+Say: "Yes! It was a glowing red rock."
+Emotion: Happy
+```
+
+**Branch B (Incorrect):**
+```
+Say: "Actually, it was red."
+Emotion: Sad
+```
+
+### Step 5: Converge
+
+1. Add new step "Story Continues"
+2. Set type to **Converge**
+3. Connect both branches to this step
+4. Add concluding speech
+
+### Step 6: Conclusion
+
+1. Add final step "Conclusion"
+2. Add **Say Text**: "The End. Thank you for listening!"
+3. Add **Bow** animation
+
+## Step 5: Block Properties
+
+Each block has configurable properties:
+
+### Say Text Block
+
+```json
+{
+  "text": "Hello, how are you?",
+  "language": "en-US",
+  "speed": 1.0,
+  "emotion": "neutral"
+}
+```
+
+### Branch Block
+
+```json
+{
+  "variable": "last_response",
+  "options": [
+    { "label": "Yes", "value": "yes", "nextStepId": "step_abc" },
+    { "label": "No", "value": "no", "nextStepId": "step_xyz" }
+  ]
+}
+```
+
+### Loop Block
+
+```json
+{
+  "iterations": 3,
+  "maxDuration": 60,
+  "children": [...]
+}
+```
+
+## Step 6: Testing Your Experiment
+
+### Preview Mode
+
+Test your experiment without running a real trial:
+
+1. Click **Preview** button
+2. Step through each block
+3. See timing and flow
+4. Test branching decisions
+
+### Simulation Mode
+
+Run with a simulated robot:
+
+1. Enable `NEXT_PUBLIC_SIMULATION_MODE=true`
+2. Start a trial
+3. Robot actions are logged but not executed
+4. Great for protocol testing
+
+## Advanced: Parallel Execution
+
+Run multiple actions simultaneously:
+
+```
+Step: Greeting
+├── Parallel Block
+│   ├── Say: "Hello!"
+│   ├── Move Arm: Wave
+│   └── Move Head: Look at participant
+```
+
+## Experiment Versioning
+
+Track protocol changes:
+
+1. **Draft** - Experiment being designed
+2. **Testing** - Being tested with participants
+3. **Ready** - Approved for data collection
+4. **Deprecated** - Superseded by newer version
+
+## Common Patterns
+
+### Linear Protocol
+
+```
+Start → Step 1 → Step 2 → Step 3 → End
+```
+
+### Branching Protocol
+
+```
+Start → Step 1
+          ├── Condition A → Step 2a
+          └── Condition B → Step 2b
+```
+
+### Loop Protocol
+
+```
+Start → Step 1 → Loop (3x) → Step 2 → End
+             ↑
+             └── (back to Step 1)
+```
+
+### Parallel Protocol
+
+```
+Start → Parallel
+          ├── Action A
+          ├── Action B
+          └── Action C
+        → Continue
+```
+
+## Troubleshooting
+
+### Block Not Connecting
+
+- Check step types are compatible
+- Ensure no circular dependencies
+- Verify conditions are complete
+
+### Robot Action Not Available
+
+- Install the robot plugin
+- Check plugin is enabled for study
+- Verify robot is connected
+
+### Timing Issues
+
+- Adjust duration estimates
+- Use explicit wait blocks
+- Test with real timing
+
+## Next Steps
+
+Now that you've designed your experiment:
+
+1. **[Running Trials](04-running-trials.md)** - Execute your experiment
+2. **[Wizard Interface](05-wizard-interface.md)** - Learn real-time control
+3. **[Robot Integration](06-robot-integration.md)** - Connect your robot

+# Check robot IP
+ssh nao@IP "ifconfig"
+
+# Test from robot
+ssh nao@IP "curl localhost:9090"
+
+# Check firewall
+sudo iptables -L
+```
+
+## Step 7: Robot Maintenance
+
+### Battery Management
+
+- Check battery before each session
+- Aim for >50% battery
+- Charge during breaks
+- Replace battery if <20% capacity
+
+### Calibration
+
+Periodically calibrate:
+- Joint positions
+- Camera alignment
+- Touch sensors
+- Sound localization
+
+### Software Updates
+
+Keep robot software updated:
+- NAOqi version
+- ROS2 packages
+- HRIStudio plugin
+
+## Security Considerations
+
+### Network Security
+
+- Use encrypted network (WPA2/WPA3)
+- Firewall robot from internet
+- Use strong passwords
+
+### SSH Access
+
+- Change default passwords
+- Use SSH keys when possible
+- Limit SSH access
+
+### Data Security
+
+- Robot camera data may be sensitive
+- Store data securely
+- Follow IRB guidelines
+
+## Simulation Mode
+
+For testing without a robot:
+
+1. Enable simulation mode in settings
+2. Or set `NEXT_PUBLIC_SIMULATION_MODE=true`
+3. All actions are simulated locally
+
+See [Simulation Mode Tutorial](09-simulation-mode.md) for details.

+
+| Metric | Description |
+|--------|-------------|
+| Total Trials | Number of scheduled trials |
+| Completed | Successfully completed trials |
+| Average Duration | Mean trial time |
+| Completion Rate | % of trials completed |
+| Failed | Trials that failed |
+| Average Steps | Mean steps per trial |
+
+## Step 5: Analyzing Event Data
+
+### Timing Analysis
+
+Calculate action durations:
+
+```python
+import json
+
+with open('trial_events.json') as f:
+    data = json.load(f)
+
+# Calculate action durations
+for event in data['events']:
+    if event['type'] == 'action_executed':
+        duration = event.get('duration', 0)
+        print(f"{event['actionName']}: {duration/1000:.1f}s")
+```
+
+### Intervention Analysis
+
+Track wizard interventions:
+
+```python
+# Count interventions by type
+interventions = [
+    e for e in data['events'] 
+    if e['type'] == 'intervention'
+]
+
+by_type = {}
+for i in interventions:
+    itype = i['data'].get('type', 'unknown')
+    by_type[itype] = by_type.get(itype, 0) + 1
+
+print(by_type)
+# {'note': 15, 'pause': 3, 'alert': 1}
+```
+
+### Branch Selection Analysis
+
+Analyze wizard decisions:
+
+```python
+# Get wizard responses
+responses = [
+    e for e in data['events']
+    if e['type'] == 'wizard_response'
+]
+
+# Count by value
+by_value = {}
+for r in responses:
+    value = r.get('selectedValue', 'unknown')
+    by_value[value] = by_value.get(value, 0) + 1
+
+print(by_value)
+# {'correct': 12, 'incorrect': 6}
+```
+
+## Step 6: Form Data Analysis
+
+### Response Aggregation
+
+Aggregate survey responses:
+
+```python
+# Calculate average rating
+ratings = [
+    r['responses']['engagement_rating']
+    for r in form_responses
+]
+
+avg_rating = sum(ratings) / len(ratings)
+print(f"Average engagement: {avg_rating:.2f}/5")
+```
+
+### Cross-Tabulation
+
+Compare responses across conditions:
+
+```
+                    | Condition A | Condition B | Total
+--------------------|------------|-------------|-------
+Robot engaged       |     4.2    |     4.5     |  4.35
+Natural interaction |     3.8    |     4.1     |  3.95
+Would use again     |     78%    |     85%     |  81%
+```
+
+## Step 7: Data Visualization

+# Tutorial 9: Simulation Mode
+
+Learn how to test HRIStudio experiments without a physical robot.
+
+## Objectives
+
+- Enable simulation mode
+- Use the mock robot server
+- Test experiments end-to-end
+- Practice trial execution
+
+## Why Simulation Mode?
+
+Simulation mode allows you to:
+
+- **Test protocols** without a robot
+- **Train wizards** before live sessions
+- **Debug experiments** in development
+- **Run pilots** without robot access
+- **Develop** on any computer
+
+## Understanding Simulation Options
+
+HRIStudio offers two simulation approaches:
+
+| Approach | Pros | Cons |
+|----------|------|------|
+| **Client-side** | No server needed, instant | Limited robot simulation |
+| **Mock Server** | Full rosbridge protocol | Requires running server |
+
+### Client-Side Simulation
+
+Simulates robot locally in the browser:
+- No network required
+- Instant startup
+- Basic action timing
+- Fake sensor data
+
+### Mock Server
+
+Full WebSocket server simulating rosbridge:
+- Complete protocol support
+- Realistic timing
+- Sensor data simulation
+- Better for integration testing
+
+## Step 1: Enable Client-Side Simulation
+
+### Quick Start
+
+1. Create or edit `hristudio/.env.local`
+2. Add:
+   ```bash
+   NEXT_PUBLIC_SIMULATION_MODE=true
+   ```
+3. Restart the dev server:
+   ```bash
+   bun dev
+   ```
+
+### Verify Enabled
+
+Look for the simulation indicator in the UI:
+
+```
+┌─────────────────────────────────────────────────────────────┐
+│  Wizard Interface                    [🔵 SIMULATION MODE] │
+├─────────────────────────────────────────────────────────────┤
+```
+
+### Features Available
+
+In simulation mode:
+
+- ✅ All robot actions execute (simulated timing)
+- ✅ Speech actions show estimated duration
+- ✅ Movement actions track position
+- ✅ Sensor data is simulated
+- ✅ Trial execution works normally
+- ❌ Real robot not controlled
+- ❌ Physical interactions not possible
+
+## Step 2: Start Mock Robot Server
+
+For more complete testing, use the mock server:
+
+### Option 1: Standalone Server
+
+```bash
+cd hristudio/scripts/mock-robot
+bun install
+bun dev
+```
+
+Server starts on `ws://localhost:9090`
+
+### Option 2: Docker
+
+```bash
+cd nao6-hristudio-integration
+docker compose -f docker-compose.yml -f docker-compose.mock.yml --profile mock up -d
+```
+
+### Verify Server Running
+
+```bash
+# Check container
+docker ps
+
+# Should show:
+# CONTAINER ID   IMAGE         STATUS
+# abc123def456   hristudio-mock-robot   Up 2 minutes
+```
+
+## Step 3: Connect to Mock Server
+
+1. Go to the **NAO Test Page**: `/nao-test`
+2. Ensure `NEXT_PUBLIC_SIMULATION_MODE` is NOT set (or set to false)
+3. Click **Connect**
+4. You should see:
+   ```
+   Connected to rosbridge
+   Subscribed to: /joint_states, /bumper, /sonar/left, ...
+   ```
+
+## Step 4: Test Robot Actions
+
+### From NAO Test Page
+
+1. **Speech Test**
+   - Enter text: "Hello, this is a test"
+   - Click **Say**
+   - See simulated speech duration
+
+2. **Movement Test**
+   - Set walk speed: 0.1 m/s
+   - Click **Walk Forward**
+   - Watch position update
+
+3. **Head Control**
+   - Set yaw: 1.0, pitch: 0.0
+   - Click **Move Head**
+   - See joint angles update
+
+### From Wizard Interface
+
+1. Start a trial
+2. Execute actions as normal
+3. Actions are sent to mock server
+4. Mock server responds with simulated data
+
+## Step 5: Simulated Actions Reference
+
+### Speech Actions
+
+| Action | Simulation Behavior |
+|--------|---------------------|
+| `say_text` | Duration = 1.5s + 300ms × word_count |
+| `say_with_emotion` | Duration = 1.5s + 300ms × word_count + emotion_overhead |
+| `wave_goodbye` | Duration = 3.0s |
+
+### Movement Actions
+
+| Action | Simulation Behavior |
+|--------|---------------------|
+| `walk_forward` | Position updates over 500ms |
+| `walk_backward` | Position updates over 500ms |
+| `turn_left` | Angle decreases over 500ms |
+| `turn_right` | Angle increases over 500ms |
+| `stop` | Velocity set to 0 |
+
+### Sensor Simulation
+
+| Sensor | Simulated Value |
+|--------|-----------------|
+| Battery | 85% ± 2% variation |
+| Joint States | Random positions ±0.1 rad |
+| Bumper | False (no contact) |
+| Sonar | 0.5-1.0m (random) |
+| Touch | False (no touch) |
+
+## Step 6: Testing Experiment Protocols
+
+### Full Protocol Test
+
+1. Enable simulation mode
+2. Create or open experiment
+3. Schedule trial
+4. Start trial in wizard interface
+5. Execute through all steps
+6. Verify timing and flow
+
+### Test Checklist
+
+- [ ] All steps execute in order
+- [ ] Branching decisions work
+- [ ] Timing estimates are accurate
+- [ ] Event log captures everything
+- [ ] No errors or warnings
+- [ ] Trial completes successfully
+
+### Debug Mode
+
+Enable verbose logging:
+
+```bash
+# In browser console, run:
+localStorage.setItem('debug', 'true')
+
+# Refresh page
+# Now see detailed action logs in console
+```
+
+## Step 7: Training Wizards
+
+Simulation mode is perfect for training:

+- [ ] Data exports correctly
+
+## Step 9: Transitioning to Real Robot
+
+When ready to test with real robot:
+
+### Step 1: Disable Simulation
+
+Remove or set to false:
+```bash
+NEXT_PUBLIC_SIMULATION_MODE=false
+```
+
+### Step 2: Connect Robot
+
+1. Start Docker services
+2. Verify robot connection
+3. Test with NAO Test Page
+
+### Step 3: Run Comparison Trial
+
+1. Run same experiment on real robot
+2. Compare timing and behavior
+3. Adjust parameters as needed
+
+### Step 4: Document Differences
+
+Note any protocol adjustments needed:
+- Timing differences
+- Action parameter changes
+- Branch criteria updates
+
+## Troubleshooting
+
+### Simulation Actions Not Working
+
+1. Check `NEXT_PUBLIC_SIMULATION_MODE=true` is set
+2. Verify no errors in browser console
+3. Try refreshing the page
+
+### Mock Server Connection Failed
+
+```bash
+# Check if server is running
+docker ps | grep mock
+
+# Check server logs
+docker compose logs mock_robot
+
+# Restart if needed
+docker compose restart mock_robot
+```
+
+### Actions Execute But Nothing Happens
+
+1. Check WebSocket URL is correct
+2. Verify port 9090 is not blocked
+3. Try client-side simulation instead
+
+## Comparison: Simulation vs Real
+
+| Aspect | Simulation | Real Robot |
+|--------|------------|------------|
+| Setup time | 1 min | 30+ min |
+| Availability | Always | Requires robot |
+| Cost | Free | Robot access needed |
+| Timing accuracy | Estimated | Actual |
+| Physical interaction | ✗ | ✓ |
+| Sensor accuracy | Fake | Real |
+| Network dependent | No | Yes |
+

+## Troubleshooting
+
+### ❌ Robot Not Responding
+**Problem:** Commands sent but robot doesn't react  
+**Solution:** 
+- Check robot is awake: Press chest button for 3 seconds
+- Verify network connectivity: `ping nao.local`
+- Use "Wake Up / Rest Robot" action in experiment
+
+### ❌ WebSocket Connection Failed
+**Problem:** HRIStudio cannot connect to robot  
+**Solution:**
+- Verify rosbridge is running: `ros2 node list | grep rosbridge`
+- Check port availability: `ss -an | grep 9090`
+- Restart integration: Kill processes and relaunch
+
+### ❌ Movements Too Fast/Unsafe
+**Problem:** Robot moves too quickly or unpredictably  
+**Solution:**
+- Reduce max velocities in plugin configuration
+- Lower movement speed parameters in actions
+- Use "Emergency Stop" action if needed
+
+### ❌ Speech Not Working
+**Problem:** Robot doesn't speak or audio issues  
+**Solution:**
+- Check robot volume settings
+- Verify text-to-speech service: `ros2 topic echo /speech`
+- Ensure speakers are functioning
+
+## Safety Guidelines
+
+### ⚠️ Important Safety Notes
+- **Clear Space** - Ensure 2m clearance around robot during movement
+- **Emergency Stop** - Keep emergency stop action easily accessible
+- **Supervision** - Never leave robot unattended during experiments
+- **Battery Monitoring** - Check battery level for long sessions
+- **Stable Surface** - Keep robot on level, stable flooring
+
+### Emergency Procedures
+```bash
+# Immediate stop via CLI
+ros2 topic pub --once /cmd_vel geometry_msgs/msg/Twist '{linear: {x: 0.0, y: 0.0, z: 0.0}, angular: {x: 0.0, y: 0.0, z: 0.0}}'
+
+# Or use HRIStudio emergency stop action
+# Add "Emergency Stop" action to experiment for quick access
+```
