## 🎯 **Key Concepts**

### Hierarchical Structure
```
Study → Experiment → Trial → Step → Action
```

### User Roles
- **Administrator**: Full system access
- **Researcher**: Create studies, design experiments
- **Wizard**: Execute trials, control robots
- **Observer**: Read-only access

### Core Workflows
1. **Study Creation** → Team setup → Participant recruitment
2. **Experiment Design** → Visual designer → Protocol validation
3. **Trial Execution** → Wizard interface → Data capture
4. **Data Analysis** → Export → Insights

---

## 🛠 **Development Commands**

| Command | Purpose |
|---------|---------|
| `bun dev` | Start development server |
| `bun build` | Build for production |
| `bun typecheck` | TypeScript validation |
| `bun lint` | Code quality checks |
| `bun db:push` | Push schema changes |
| `bun db:seed` | Seed test data |
| `bun db:studio` | Open database GUI |

---

## 🌐 **API Reference**

### Base URL
```
http://localhost:3000/api/trpc/
```

### Key Routers
- **`auth`**: Login, logout, registration
- **`studies`**: CRUD operations, team management
- **`experiments`**: Design, configuration, validation
- **`participants`**: Registration, consent, demographics
- **`trials`**: Execution, monitoring, data capture
- **`robots`**: Integration, communication, actions, plugins
- **`admin`**: Repository management, system settings

### Example Usage
```typescript
// Get user's studies
const studies = api.studies.getUserStudies.useQuery();

// Create new experiment
const createExperiment = api.experiments.create.useMutation();
```

---

## 🗄️ **Database Quick Reference**

### Core Tables
```sql
users              -- Authentication & profiles
studies            -- Research projects
experiments        -- Protocol templates
participants       -- Study participants
trials             -- Experiment instances
steps              -- Experiment phases
trial_events       -- Execution logs
robots             -- Available platforms
```

### Key Relationships
```
studies → experiments → trials
studies → participants
trials → trial_events
experiments → steps
```

---

## 🎨 **UI Components**

### Layout Components
```typescript
// Page wrapper with navigation
<PageLayout title="Studies" description="Manage research studies">
  <StudiesTable />
</PageLayout>

// Entity forms (unified pattern)
<EntityForm 
  mode="create"
  entityName="Study"
  form={form}
  onSubmit={handleSubmit}
/>

// Data tables (consistent across entities)
<DataTable 
  columns={studiesColumns}
  data={studies}
  searchKey="name"
/>
```

### Form Patterns
```typescript
// Standard form setup
const form = useForm<StudyFormData>({
  resolver: zodResolver(studySchema),
  defaultValues: { /* ... */ }
});

// Unified submission
const onSubmit = async (data: StudyFormData) => {
  await createStudy.mutateAsync(data);
  router.push(`/studies/${result.id}`);
};
```

---

## 🔐 **Authentication**

### Protecting Routes
```typescript
// Middleware protection
export default withAuth(
  function middleware(request) {
    // Route logic
  },
  {
    callbacks: {
      authorized: ({ token }) => !!token,
    },
  }
);

// Component protection
const { data: session, status } = useSession();
if (status === "loading") return <Loading />;
if (!session) return <SignIn />;
```

### Role Checking
```typescript
// Server-side
ctx.session.user.role === "administrator"

// Client-side
import { useSession } from "next-auth/react";
const hasRole = (role: string) => session?.user.role === role;
```

---

## 🤖 **Robot Integration**

### Core Blocks System
```typescript
// Core blocks loaded from hristudio-core repository
await registry.loadCoreBlocks();

// Block categories:
// - Events (4): when_trial_starts, when_participant_speaks, etc.
// - Wizard Actions (6): wizard_say, wizard_gesture, etc.  
// - Control Flow (8): wait, repeat, if_condition, etc.
// - Observation (8): observe_behavior, record_audio, etc.
```

### Plugin Repository System
```typescript
// Repository sync (admin only)
await api.admin.repositories.sync.mutate({ id: repoId });

// Plugin installation
await api.robots.plugins.install.mutate({
  studyId: 'study-id',
  pluginId: 'plugin-id'
});

// Get study plugins
const plugins = api.robots.plugins.getStudyPlugins.useQuery({
  studyId: selectedStudyId
});
```

### Plugin Structure
```typescript
interface Plugin {
  id: string;
  name: string;
  version: string;
  trustLevel: 'official' | 'verified' | 'community';
  actionDefinitions: RobotAction[];
  metadata: {
    platform: string;
    category: string;
    repositoryId: string;
  };
}
```

### Repository Integration
- **Live Repository**: `https://repo.hristudio.com`
- **Core Repository**: `https://core.hristudio.com` 
- **Auto-sync**: Admin dashboard → Repositories → Sync
- **Plugin Store**: Browse → Install → Use in experiments

---

## 📊 **Common Patterns**

### Error Handling
```typescript
try {
  await mutation.mutateAsync(data);
  toast.success("Success!");
  router.push("/success-page");
} catch (error) {
  setError(error.message);
  toast.error("Failed to save");
}
```

### Loading States
```typescript
const { data, isLoading, error } = api.studies.getAll.useQuery();

if (isLoading) return <Skeleton />;
if (error) return <ErrorMessage error={error} />;
return <DataTable data={data} />;
```

### Form Validation
```typescript
const schema = z.object({
  name: z.string().min(1, "Name required"),
  description: z.string().min(10, "Description too short"),
  duration: z.number().min(5, "Minimum 5 minutes")
});
```

## 🚀 **Deployment**

### Vercel Deployment
```bash
# Install Vercel CLI
bun add -g vercel

# Deploy
vercel --prod

# Environment variables
vercel env add DATABASE_URL
vercel env add NEXTAUTH_SECRET
vercel env add CLOUDFLARE_R2_*
```

### Environment Variables
```bash
# Required
DATABASE_URL=postgresql://...
NEXTAUTH_URL=https://your-domain.com
NEXTAUTH_SECRET=your-secret

# Storage
CLOUDFLARE_R2_ACCOUNT_ID=...
CLOUDFLARE_R2_ACCESS_KEY_ID=...
CLOUDFLARE_R2_SECRET_ACCESS_KEY=...
CLOUDFLARE_R2_BUCKET_NAME=hristudio-files
```

## 🔧 **Troubleshooting**

### Common Issues

**Build Errors**
```bash
# Clear cache and rebuild
rm -rf .next
bun run build
```

**Database Issues**
```bash
# Reset database
bun db:push --force
bun db:seed
```

**TypeScript Errors**
```bash
# Check types
bun typecheck

# Common fixes
# - Check imports
# - Verify API return types
# - Update schema types
```

### Performance Tips
- Use React Server Components where possible
- Implement proper pagination for large datasets
- Add database indexes for frequently queried fields
- Use optimistic updates for better UX

## 🎯 **Quick Tips**
### Quick Tips

### Development Workflow
1. Always run `bun typecheck` before commits
2. Use the unified `EntityForm` for all CRUD operations
3. Follow the established component patterns
4. Add proper error boundaries for new features
5. Test with multiple user roles
6. Sync plugin repositories after setup for full functionality

### Code Standards
- Use TypeScript strict mode
- Prefer Server Components over Client Components
- Implement proper error handling
- Add loading states for all async operations
- Use Zod for input validation

### Best Practices
- Keep components focused and composable
- Use the established file naming conventions
- Implement proper RBAC for new features
- Add comprehensive logging for debugging
- Follow accessibility guidelines (WCAG 2.1 AA)
- Use repository-based plugins instead of hardcoded robot actions
- Test plugin installation/uninstallation in different studies
