## Core Architecture Principles

### 1. Configuration-Driven Everything

**Principle**: Zero HTML/JSX duplication - All UI rendered from configuration.

**Implementation**:
- **Frontend**: Config files in `/config/pages/` and `/config/snippets/`
- **Backend**: DRF serializers and ViewSet actions
- **Templates**: 4 universal templates (Dashboard, Table, Form, System)

**Benefits**:
- Single source of truth
- Easy maintenance
- Consistent UI/UX
- Rapid feature development

### 2. Multi-Tenancy Foundation

**Principle**: Complete account isolation with automatic filtering.

**Implementation**:
- All models inherit `AccountBaseModel`
- All ViewSets inherit `AccountModelViewSet`
- Middleware injects account context from JWT
- Site > Sector hierarchy for content organization

**Benefits**:
- Data security
- Scalability
- Resource isolation
- Simplified access control

### 3. Template System (4 Universal Templates)

**Principle**: Reusable templates for all page types.

| Template | Purpose | Usage |
|----------|---------|-------|
| **DashboardTemplate** | Module home pages | KPIs, workflow steps, charts |
| **TablePageTemplate** | CRUD table pages | Keywords, Clusters, Tasks, etc. |
| **FormPageTemplate** | Settings/form pages | Settings, Integration, etc. |
| **SystemPageTemplate** | System/admin pages | Logs, Status, Monitoring |

### 4. Unified AI Processor

**Principle**: Single interface for all AI operations.

**Implementation**:
- Single `AIEngine` class orchestrates all AI operations
- All AI functions inherit from `BaseAIFunction`
- Manual and automated workflows use same functions
- Account-specific API keys and model configuration

**Benefits**:
- Code reusability
- Consistent error handling
- Unified logging
- Easy to extend

### 5. Module-Based Organization

**Principle**: Clear module boundaries with shared utilities.

**Modules**:
- **Planner**: Keywords, Clusters, Ideas
- **Writer**: Tasks, Content, Images
- **Thinker**: Prompts, Author Profiles, Strategies, Image Testing
- **System**: Settings, Integrations, AI Configuration
- **Billing**: Credits, Transactions, Usage
- **Auth**: Accounts, Users, Sites, Sectors

- JWT settings
- Celery configuration

**Frontend Environment Variables**:
- Backend API URL
- Environment (development/production)

**Infrastructure Environment Variables**:
- PostgreSQL credentials
- pgAdmin credentials
- FileBrowser configuration

### Health Checks

**Backend Health Check**:
- Endpoint: `/api/v1/system/status/`
- Interval: 30 seconds
- Timeout: 10 seconds
- Retries: 3

**PostgreSQL Health Check**:
- Command: `pg_isready`
- Interval: 20 seconds
- Timeout: 3 seconds
- Retries: 5

**Redis Health Check**:
- Command: `redis-cli ping`
- Interval: 20 seconds
- Timeout: 3 seconds
- Retries: 5

### Scaling Considerations

**Horizontal Scaling**:
- Multiple Celery workers can be added
- Multiple backend instances can be added (with load balancer)
- Frontend can be scaled independently

**Vertical Scaling**:
- Database can be scaled with more resources
- Redis can be scaled with more memory
- Containers can be allocated more CPU/memory

### Backup & Recovery

**Database Backups**:
- PostgreSQL dumps stored in `/data/backups`
- Automated backup scripts
- Point-in-time recovery support

**Volume Backups**:
- Docker volume backups
- Application code backups
- Configuration backups

---

### Troubleshooting

#### Common Issues

**1. Port Already in Use**:
```bash
# Check what's using the port
sudo lsof -i :8011
sudo lsof -i :8021

# Stop conflicting services or change ports in docker-compose
```

**2. Network Not Found**:
```bash
# Recreate network
docker network rm igny8_net
docker network create igny8_net

# Restart services
docker compose -f docker-compose.app.yml -p igny8-app restart
```

**3. Database Connection Failed**:
```bash
# Check PostgreSQL is running
docker ps | grep postgres

# Check network connectivity
docker exec igny8_backend ping postgres

# Verify credentials in docker-compose
```

**4. Permission Denied**:
```bash
# Fix directory permissions
sudo chown -R $USER:$USER /data/app
sudo chmod -R 755 /data/app
```

**5. Caddy SSL Issues**:
```bash
# Check Caddy logs
docker logs igny8_caddy

# Verify domain DNS points to server
nslookup igny8.com

# Check firewall allows port 80/443
sudo ufw status
```
