+
+## Technology Stack
+
+### Backend
+- **FastAPI**: Modern, fast web framework for building APIs
+- **SQLAlchemy**: SQL toolkit and ORM
+- **PostgreSQL**: Relational database
+- **Alembic**: Database migration tool
+- **Python-Jose**: JWT token handling
+- **Passlib**: Password hashing with bcrypt
+
+### Frontend
+- **React**: UI library
+- **TypeScript**: Type-safe JavaScript
+- **Axios**: HTTP client
+- **React Router**: Client-side routing
+
+### Infrastructure
+- **Docker**: Containerization
+- **Docker Compose**: Multi-container orchestration
+
+## Core Components
+
+### 1. Authentication System
+
+#### JWT Token Flow
+```
+1. User submits credentials (username/password)
+2. Backend verifies credentials
+3. Backend generates JWT token with:
+   - user_id (sub)
+   - tenant_id
+   - role
+   - expiration time
+4. Frontend stores token in localStorage
+5. All subsequent requests include token in Authorization header
+6. Backend validates token and extracts user context
+```
+
+#### Password Security
+- Passwords are hashed using bcrypt with automatic salt generation
+- Password hashes are never exposed in API responses
+- Plaintext passwords are never logged or stored
+
+#### Token Security
+- Tokens expire after 30 minutes (configurable)
+- Tokens are signed with HS256 algorithm
+- Secret key must be at least 32 characters
+
+### 2. Multi-Tenancy
+
+#### Data Isolation
+Every database query is automatically scoped to the user's tenant:
+
+```python
+# Example: Listing hosts
+hosts = db.query(Host).filter(Host.tenant_id == current_user.tenant_id).all()
+```
+
+#### Tenant Creation
+- Default tenant is created automatically on first user registration
+- Admin users can create additional tenants
+- Users are assigned to exactly one tenant
+
+#### Cross-Tenant Access
+- Regular users: Can only access data in their tenant
+- Admin users: Can access all data in their tenant
+- Super-admin (future): Could access multiple tenants
+
+### 3. Role-Based Access Control (RBAC)
+
+#### Roles
+- **user**: Standard user with read/write access to their tenant's data
+- **admin**: Elevated privileges within their tenant
+  - Can manage users in their tenant
+  - Can create/modify/delete resources
+  - Can view all data in their tenant
+
+#### Permission Enforcement
+```python
+# Endpoint requiring admin role
+@router.get("/users")
+async def list_users(
+    current_user: User = Depends(require_role(["admin"]))
+):
+    # Only admins can access this
+    pass
+```
+
+### 4. Database Schema
+
+#### Core Tables
+
+**tenants**
+- id (PK)
+- name (unique)
+- description
+- created_at
+
+**users**
+- id (PK)
+- username (unique)
+- password_hash
+- role
+- tenant_id (FK → tenants)
+- is_active
+- created_at
+
+**hosts**
+- id (PK)
+- hostname
+- ip_address
+- os
+- tenant_id (FK → tenants)
+- host_metadata (JSON)
+- created_at
+- last_seen
+
+**cases**
+- id (PK)
+- title
+- description
+- status (open, closed, investigating)
+- severity (low, medium, high, critical)
+- tenant_id (FK → tenants)
+- created_at
+- updated_at
+
+**artifacts**
+- id (PK)
+- artifact_type (hash, ip, domain, email, etc.)
+- value
+- description
+- case_id (FK → cases)
+- artifact_metadata (JSON)
+- created_at
+
+#### Relationships
+```
+tenants (1) ──< (N) users
+tenants (1) ──< (N) hosts
+tenants (1) ──< (N) cases
+cases (1) ──< (N) artifacts
+```
+
+### 5. API Design
+
+#### RESTful Principles
+- Resources are nouns (users, hosts, cases)
+- HTTP methods represent actions (GET, POST, PUT, DELETE)
+- Proper status codes (200, 201, 401, 403, 404)
+
+#### Authentication
+All endpoints except `/auth/register` and `/auth/login` require authentication.
+
+```
+Authorization: Bearer <jwt_token>
+```
+
+#### Response Format
+Success:
+```json
+{
+  "id": 1,
+  "username": "john",
+  "role": "user",
+  "tenant_id": 1
+}
+```
+
+Error:
+```json
+{
+  "detail": "User not found"
+}
+```
+
+### 6. Frontend Architecture
+
+#### Component Structure
+```
+src/
+├── components/        # Reusable UI components
+│   └── PrivateRoute.tsx
+├── context/          # React Context providers
+│   └── AuthContext.tsx
+├── pages/           # Page components
+│   ├── Login.tsx
+│   └── Dashboard.tsx
+├── utils/           # Utilities
+│   └── api.ts       # API client
+├── App.tsx          # Main app component
+└── index.tsx        # Entry point
+```
+
+#### State Management
+- **AuthContext**: Global authentication state
+  - Current user
+  - Login/logout functions
+  - Loading state
+  - Authentication status
+
+#### Routing
+```
+/login        → Login page (public)
+/             → Dashboard (protected)
+/*            → Redirect to / (protected)
+```
+
+### 7. Security Architecture
+
+#### Authentication Flow
+1. Frontend sends credentials to `/api/auth/login`
+2. Backend validates and returns JWT token
+3. Frontend stores token in localStorage
+4. Token included in all API requests
+5. Backend validates token on each request
+
+#### Authorization Flow
+1. Extract JWT from Authorization header
+2. Verify token signature and expiration
+3. Extract user_id from token payload
+4. Load user from database
+5. Check user's role for endpoint access
+6. Apply tenant scoping to queries
+
+#### Security Headers
+```python
+# CORS configuration
+allow_origins=["http://localhost:3000"]
+allow_credentials=True
+allow_methods=["*"]
+allow_headers=["*"]
+```
+
+## Data Flow Examples
+
+### User Registration
+```
+1. POST /api/auth/register
+   {username: "john", password: "pass123"}
+2. Backend hashes password
+3. Create default tenant if needed
+4. Create user record
+5. Return user object (without password_hash)
+```
+
+### Host Ingestion
+```
+1. Velociraptor sends data to POST /api/ingestion/ingest
+   - Must include valid JWT token
+2. Extract tenant_id from current user
+3. Find or create host with hostname
+4. Update host metadata
+5. Return success response
+```
+
+### Listing Resources
+```
+1. GET /api/hosts with Authorization header
+2. Validate JWT token
+3. Extract tenant_id from user
+4. Query: SELECT * FROM hosts WHERE tenant_id = ?
+5. Return filtered results
+```
+

+```
+
+## Performance Considerations
+
+### Database Indexing
+- Primary keys on all tables
+- Unique index on usernames
+- Index on tenant_id columns for fast filtering
+- Index on hostname for host lookups
+
+### Query Optimization
+- Always filter by tenant_id early in queries
+- Use pagination for large result sets (skip/limit)
+- Lazy load relationships when not needed
+
+### Caching (Future)
+- Cache tenant information
+- Cache user profiles
+- Cache frequently accessed hosts
+
+## Monitoring & Logging
+
+### Health Checks
+```
+GET /health → {"status": "healthy"}
+```
+
+### Logging
+- Request logging via Uvicorn
+- Error tracking in application logs
+- Database query logging (development only)
+
+### Metrics (Future)
+- Request count per endpoint
+- Authentication success/failure rate
+- Database query performance
+- Active user count
+
+## Migration Strategy
+
+### Database Migrations
+```bash
+# Create migration
+alembic revision --autogenerate -m "Description"
+
+# Apply migration
+alembic upgrade head
+
+# Rollback
+alembic downgrade -1
+```
+
+### Schema Evolution
+1. Create migration for schema changes
+2. Test migration in development
+3. Apply to staging environment
+4. Verify data integrity
+5. Apply to production during maintenance window
+
+## Testing Strategy
+
+### Unit Tests (Future)
+- Test individual functions
+- Mock database connections
+- Test password hashing
+- Test JWT token creation/verification
+
+### Integration Tests (Future)
+- Test API endpoints
+- Test authentication flow
+- Test multi-tenancy isolation
+- Test RBAC enforcement
+
+### Manual Testing
+- Use test_api.sh script
+- Use FastAPI's /docs interface
+- Test frontend authentication flow
+
+## Future Enhancements
+
+### Phase 2
+- Refresh tokens for longer sessions
+- Password reset functionality
+- Email verification
+- Two-factor authentication (2FA)
+
+### Phase 3
+- Audit logging
+- Advanced search and filtering
+- Real-time notifications
+- Velociraptor direct integration
+
+### Phase 4
+- Machine learning for threat detection
+- Automated playbooks
+- Integration with SIEM systems
+- Advanced reporting and analytics
+
+## Troubleshooting Guide
+
+### Common Issues
+
+**Token Expired**
+- Tokens expire after 30 minutes
+- User must login again
+- Consider implementing refresh tokens
+
+**Permission Denied**
+- User lacks required role
+- Check user's role in database
+- Verify endpoint requires correct role
+
+**Data Not Visible**
+- Check tenant_id of user
+- Verify data belongs to correct tenant
+- Ensure tenant_id is being applied to queries
+
+**Database Connection Failed**
+- Check DATABASE_URL environment variable
+- Verify PostgreSQL is running
+- Check network connectivity
+
+## Development Guidelines
+
+### Adding New Endpoints
+
+1. Create route in `app/api/routes/`
+2. Add authentication dependency
+3. Apply tenant scoping to queries
+4. Add role check if needed
+5. Create Pydantic schemas
+6. Update router registration in main.py
+7. Test with /docs interface
+
+### Adding New Models
+
+1. Create model in `app/models/`
+2. Add tenant_id foreign key
+3. Create migration
+4. Create Pydantic schemas
+5. Create CRUD routes
+6. Apply tenant scoping
+
+### Code Style
+
+- Follow PEP 8 for Python
+- Use type hints
+- Write docstrings for functions
+- Keep functions small and focused
+- Use meaningful variable names

+ACCESS_TOKEN_EXPIRE_MINUTES=30
+ALGORITHM=HS256
+```
+
+### Frontend
+```bash
+REACT_APP_API_URL=https://api.your-domain.com
+```
+
+## Load Balancer Configuration
+
+### Backend
+```nginx
+upstream backend {
+    server backend1:8000;
+    server backend2:8000;
+    server backend3:8000;
+}
+
+server {
+    listen 443 ssl;
+    server_name api.your-domain.com;
+
+    ssl_certificate /path/to/cert.pem;
+    ssl_certificate_key /path/to/key.pem;
+
+    location / {
+        proxy_pass http://backend;
+        proxy_set_header Host $host;
+        proxy_set_header X-Real-IP $remote_addr;
+        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
+        proxy_set_header X-Forwarded-Proto $scheme;
+    }
+}
+```
+
+### Frontend
+```nginx
+server {
+    listen 443 ssl;
+    server_name your-domain.com;
+
+    ssl_certificate /path/to/cert.pem;
+    ssl_certificate_key /path/to/key.pem;
+
+    root /var/www/velocicompanion/build;
+    index index.html;
+
+    location / {
+        try_files $uri /index.html;
+    }
+
+    # Cache static assets
+    location ~* \.(js|css|png|jpg|jpeg|gif|ico|svg)$ {
+        expires 1y;
+        add_header Cache-Control "public, immutable";
+    }
+}
+```
+
+## Scaling Considerations
+
+### Horizontal Scaling
+- Run multiple backend instances behind load balancer
+- Use managed PostgreSQL with read replicas
+- Serve frontend from CDN
+- Implement caching layer (Redis)
+
+### Vertical Scaling

+- **Backend**: 2GB RAM per instance, 2+ CPU cores
+- **Frontend**: Static files, minimal resources
+
+### Performance Optimization
+- [ ] Enable database connection pooling
+- [ ] Add Redis cache for sessions
+- [ ] Implement request rate limiting
+- [ ] Optimize database queries
+- [ ] Add database indexes
+- [ ] Enable GZIP compression
+
+## Disaster Recovery
+
+### Backup Strategy
+- **Database**: Daily full backups, hourly incremental
+- **Files**: Daily backup of configuration files
+- **Retention**: 30 days of backups
+- **Off-site**: Copy backups to different region
+
+### Recovery Procedures
+1. Restore database from latest backup
+2. Deploy latest application version
+3. Run database migrations if needed
+4. Verify system functionality
+5. Update DNS if needed
+
+### RTO/RPO
+- **RTO** (Recovery Time Objective): 4 hours
+- **RPO** (Recovery Point Objective): 1 hour
+
+## Maintenance
+
+### Regular Tasks
+- [ ] Review logs weekly

+- [ ] Security patches: Apply within 7 days
+- [ ] Database optimization quarterly
+- [ ] Review and rotate access credentials quarterly
+
+### Update Process
+1. Test updates in staging environment
+2. Schedule maintenance window
+3. Notify users of planned downtime
+4. Create backup before update
+5. Deploy updates
+6. Run smoke tests
+7. Monitor for issues
+
+## Rollback Plan
+
+If deployment fails:
+
+1. **Immediate**
+   ```bash
+   # Rollback to previous version
+   docker-compose down
+   git checkout <previous-tag>
+   docker-compose up -d
+   ```
+
+2. **Database Rollback**
+   ```bash
+   # Rollback migration
+   alembic downgrade -1
+   ```
+

+# Phase 5: Distributed LLM Routing Architecture
+
+## Overview
+
+Phase 5 introduces a sophisticated distributed Large Language Model (LLM) routing system that intelligently classifies tasks and routes them to specialized models across multiple GPU nodes (GB10 devices). This architecture enables efficient utilization of computational resources and optimal model selection based on task requirements.
+
+## Architecture Components
+
+The system consists of four containerized components that work together to provide intelligent, scalable LLM processing:
+
+### 1. Router Agent (LLM Classifier + Policy Engine)
+
+**Module**: `app/core/llm_router.py`
+
+The Router Agent is responsible for:
+- **Request Classification**: Analyzes incoming requests to determine the task type
+- **Model Selection**: Routes requests to the most appropriate specialized model
+- **Policy Enforcement**: Applies routing rules based on configured policies
+
+**Task Types & Model Routing:**
+
+| Task Type | Model | Use Case |
+|-----------|-------|----------|
+| `general_reasoning` | DeepSeek | Complex analysis and reasoning |
+| `multilingual` | Qwen72 / Aya | Translation and multilingual tasks |
+| `structured_parsing` | Phi-4 | Structured data extraction |
+| `rule_generation` | Qwen-Coder | Code and rule generation |
+| `adversarial_reasoning` | LLaMA 3.1 | Threat and adversarial analysis |
+| `classification` | Granite Guardian | Pure classification tasks |
+
+**Classification Logic:**
+```python
+from app.core.llm_router import get_llm_router
+
+router = get_llm_router()
+routing_decision = router.route_request({
+    "prompt": "Analyze this threat...",
+    "task_hints": ["threat", "adversary"]
+})
+# Routes to LLaMA 3.1 for adversarial reasoning
+```
+
+### 2. Job Scheduler (GPU Load Balancer)
+
+**Module**: `app/core/job_scheduler.py`
+
+The Job Scheduler manages:
+- **Node Selection**: Determines which GB10 device is available
+- **Resource Monitoring**: Tracks GPU VRAM and compute utilization
+- **Parallelization Decisions**: Determines if jobs should be distributed
+- **Serial Chaining**: Handles multi-step reasoning workflows
+
+**GPU Node Configuration:**
+
+**GB10 Node 1** (`gb10-node-1:8001`)
+- **Total VRAM**: 80 GB
+- **Models Loaded**: DeepSeek, Qwen72
+- **Primary Use**: General reasoning and multilingual tasks
+
+**GB10 Node 2** (`gb10-node-2:8001`)
+- **Total VRAM**: 80 GB
+- **Models Loaded**: Phi-4, Qwen-Coder, LLaMA 3.1, Granite Guardian
+- **Primary Use**: Specialized tasks (parsing, coding, classification, threat analysis)
+
+**Scheduling Strategies:**
+
+1. **Single Node Execution**
+   - Default for simple requests
+   - Selected based on lowest compute utilization
+   - Requires sufficient VRAM for model
+
+2. **Parallel Execution**
+   - Distributes work across multiple nodes
+   - Used for batch processing or high-priority jobs
+   - Automatic load balancing
+
+3. **Serial Chaining**
+   - Multi-step dependent operations
+   - Sequential execution with context passing
+   - Used for complex reasoning workflows
+
+4. **Queued Execution**
+   - When all nodes are at capacity
+   - Priority-based queue management
+   - Automatic dispatch when resources available
+
+**Example Usage:**
+```python
+from app.core.job_scheduler import get_job_scheduler, Job
+
+scheduler = get_job_scheduler()
+job = Job(
+    job_id="threat_analysis_001",
+    model="llama31",
+    priority=1,
+    estimated_vram_gb=10,
+    requires_parallel=False,
+    requires_chaining=False,
+    payload={"prompt": "..."}
+)
+
+scheduling_decision = await scheduler.schedule_job(job)
+# Returns node assignment and execution mode
+```
+
+### 3. LLM Pool (OpenAI-Compatible Endpoints)
+
+**Module**: `app/core/llm_pool.py`
+
+The LLM Pool provides:
+- **Unified Interface**: OpenAI-compatible API for all models
+- **Endpoint Management**: Tracks availability and health
+- **Parallel Execution**: Simultaneous multi-model requests
+- **Error Handling**: Graceful fallback on failures
+
+**Available Endpoints:**
+
+| Model | Endpoint | Node | Specialization |
+|-------|----------|------|----------------|
+| DeepSeek | `http://gb10-node-1:8001/deepseek` | Node 1 | General reasoning |
+| Qwen72 | `http://gb10-node-1:8001/qwen72` | Node 1 | Multilingual |
+| Phi-4 | `http://gb10-node-2:8001/phi4` | Node 2 | Structured parsing |
+| Qwen-Coder | `http://gb10-node-2:8001/qwen-coder` | Node 2 | Code generation |
+| LLaMA 3.1 | `http://gb10-node-2:8001/llama31` | Node 2 | Adversarial reasoning |
+| Granite Guardian | `http://gb10-node-2:8001/granite-guardian` | Node 2 | Classification |
+
+**Example Usage:**
+```python
+from app.core.llm_pool import get_llm_pool
+
+pool = get_llm_pool()
+
+# Single model call
+result = await pool.call_model(
+    model_name="llama31",
+    prompt="Analyze this threat pattern...",
+    parameters={"temperature": 0.7, "max_tokens": 2048}
+)
+
+# Multiple models in parallel
+results = await pool.call_multiple_models(
+    model_names=["llama31", "deepseek"],
+    prompt="Complex threat analysis...",
+    parameters={"temperature": 0.7}
+)
+```
+
+### 4. Merger Agent (Result Synthesizer)
+
+**Module**: `app/core/merger_agent.py`
+
+The Merger Agent provides:
+- **Result Combination**: Intelligently merges outputs from multiple models
+- **Strategy Selection**: Multiple merging strategies for different use cases
+- **Quality Assessment**: Evaluates and ranks responses
+- **Consensus Building**: Determines agreement across models
+
+**Merging Strategies:**
+
+1. **Consensus** (`MergeStrategy.CONSENSUS`)
+   - Takes majority vote for classifications
+   - Selects most common response
+   - Best for: Classification tasks, binary decisions
+
+2. **Weighted** (`MergeStrategy.WEIGHTED`)
+   - Weights results by confidence scores
+   - Selects highest confidence response
+   - Best for: When models provide confidence scores
+
+3. **Concatenate** (`MergeStrategy.CONCATENATE`)
+   - Combines all responses sequentially
+   - Preserves all information
+   - Best for: Comprehensive analysis requiring multiple perspectives
+
+4. **Best Quality** (`MergeStrategy.BEST_QUALITY`)
+   - Selects highest quality response based on metrics
+   - Considers length, completeness, formatting
+   - Best for: Text generation, detailed explanations
+
+5. **Ensemble** (`MergeStrategy.ENSEMBLE`)
+   - Synthesizes insights from all models
+   - Creates comprehensive summary
+   - Best for: Complex analysis requiring synthesis
+
+**Example Usage:**
+```python
+from app.core.merger_agent import get_merger_agent, MergeStrategy
+
+merger = get_merger_agent()
+
+# Multiple model results
+results = [
+    {"model": "llama31", "response": "...", "confidence": 0.9},
+    {"model": "deepseek", "response": "...", "confidence": 0.85}
+]
+
+# Merge with consensus strategy
+merged = merger.merge_results(results, strategy=MergeStrategy.CONSENSUS)
+```

+        print(f"Chain result: {result['result']}")
+```
+
+## Integration with Existing Features
+
+### Integration with Threat Intelligence (Phase 4)
+
+The distributed LLM system enhances threat intelligence analysis:
+
+```python
+from app.core.threat_intel import get_threat_analyzer
+from app.core.llm_pool import get_llm_pool
+
+async def enhanced_threat_analysis(host_id):
+    # Step 1: Traditional ML analysis
+    analyzer = get_threat_analyzer()
+    ml_result = analyzer.analyze_host(host_data)
+    
+    # Step 2: LLM-based deep analysis if score is concerning
+    if ml_result["score"] > 0.6:
+        pool = get_llm_pool()
+        llm_result = await pool.call_model(
+            "llama31",
+            f"Deep analysis of threat with score {ml_result['score']}: {host_data}",
+            {"temperature": 0.3}
+        )
+        
+        return {
+            "ml_analysis": ml_result,
+            "llm_analysis": llm_result,
+            "recommendation": "quarantine" if ml_result["score"] > 0.8 else "investigate"
+        }
+```
+
+### Integration with Automated Playbooks (Phase 4)
+
+LLM routing can trigger automated responses:
+
+```python
+from app.core.playbook_engine import get_playbook_engine
+
+async def llm_triggered_playbook(threat_analysis):
+    if threat_analysis["result"]["severity"] == "critical":
+        engine = get_playbook_engine()
+        await engine.execute_playbook(
+            playbook={
+                "actions": [
+                    {"type": "isolate_host", "params": {"host_id": host_id}},
+                    {"type": "send_notification", "params": {"message": "Critical threat detected"}},
+                    {"type": "create_case", "params": {"title": "Auto-generated from LLM analysis"}}
+                ]
+            },
+            context=threat_analysis
+        )
+```
+
+## Deployment
+
+### Docker Compose Configuration
+
+Add LLM node services to `docker-compose.yml`:
+
+```yaml
+services:
+  # Existing services...
+  
+  llm-node-1:
+    image: vllm/vllm-openai:latest
+    ports:
+      - "8001:8001"
+    environment:
+      - NVIDIA_VISIBLE_DEVICES=0,1
+    volumes:
+      - ./models:/models
+    command: >
+      --model /models/deepseek
+      --host 0.0.0.0
+      --port 8001
+    deploy:
+      resources:
+        reservations:
+          devices:
+            - driver: nvidia
+              count: 2
+              capabilities: [gpu]
+  
+  llm-node-2:
+    image: vllm/vllm-openai:latest
+    ports:
+      - "8002:8001"
+    environment:
+      - NVIDIA_VISIBLE_DEVICES=2,3
+    volumes:
+      - ./models:/models
+    command: >
+      --model /models/phi4
+      --host 0.0.0.0
+      --port 8001
+    deploy:
+      resources:
+        reservations:
+          devices:
+            - driver: nvidia
+              count: 2
+              capabilities: [gpu]
+```
+
+### Environment Variables
+
+Add to `.env`:
+
+```bash
+# Phase 5: LLM Configuration
+LLM_NODE_1_URL=http://gb10-node-1:8001
+LLM_NODE_2_URL=http://gb10-node-2:8001
+LLM_ENABLE_PARALLEL=true
+LLM_MAX_PARALLEL_JOBS=4
+LLM_DEFAULT_TIMEOUT=60
+```
+
+## Performance Considerations
+
+### Resource Allocation
+
+- **DeepSeek**: ~40GB VRAM (high priority)
+- **Qwen72**: ~35GB VRAM (medium priority)
+- **Phi-4**: ~15GB VRAM (fast inference)
+- **Qwen-Coder**: ~20GB VRAM
+- **LLaMA 3.1**: ~25GB VRAM
+- **Granite Guardian**: ~10GB VRAM (classification only)
+
+### Load Balancing
+
+The scheduler automatically:
+- Monitors VRAM usage on each node
+- Tracks compute utilization (0.0-1.0)
+- Routes requests to less loaded nodes
+- Queues jobs when capacity is reached
+
+### Optimization Tips
+
+1. **Use task_hints**: Helps router select optimal model faster
+2. **Enable parallelization**: For batch jobs over 10 items
+3. **Monitor node status**: Use `/api/llm/nodes` endpoint
+4. **Set appropriate temperatures**: Lower (0.3) for analysis, higher (0.7) for generation
+5. **Leverage caching**: Repeated prompts hit cache layer
+
+## Security
+
+- All LLM endpoints require authentication
+- Admin-only node status updates
+- Tenant isolation maintained
+- Audit logging for all LLM requests
+- Rate limiting per user/tenant
+
+## Future Enhancements
+
+- [ ] Model fine-tuning pipeline
+- [ ] Custom model deployment
+- [ ] Advanced caching layer
+- [ ] Multi-region deployment
+- [ ] Real-time model swapping
+- [ ] Automated model selection via meta-learning
+- [ ] Integration with external model APIs (OpenAI, Anthropic)
+- [ ] Cost tracking and optimization
+
+## Conclusion
+
+Phase 5 provides a production-ready distributed LLM routing architecture that intelligently manages computational resources while optimizing for task-specific model selection. The system integrates seamlessly with existing threat hunting capabilities to provide enhanced analysis and automated decision-making.

+
+# Check service status
+docker-compose ps
+```
+
+Expected output:
+```
+NAME                COMMAND                  SERVICE             STATUS              PORTS
+threathunt-backend-1   "sh -c 'alembic upgr…"   backend             running             0.0.0.0:8000->8000/tcp
+threathunt-db-1        "docker-entrypoint.s…"   db                  running             0.0.0.0:5432->5432/tcp
+threathunt-frontend-1  "docker-entrypoint.s…"   frontend            running             0.0.0.0:3000->3000/tcp
+```
+
+## Step 2: Verify Backend is Running
+
+```bash
+# Check backend health
+curl http://localhost:8000/health
+
+# Expected response:
+# {"status":"healthy"}
+
+# View API documentation
+open http://localhost:8000/docs
+```
+
+## Step 3: Access the Frontend
+
+Open your browser and navigate to:
+```
+http://localhost:3000
+```
+
+You should see the VelociCompanion login page.
+
+## Step 4: Create Your First User
+
+### Option A: Via API (using curl)
+
+```bash
+# Register a new user
+curl -X POST http://localhost:8000/api/auth/register \
+  -H "Content-Type: application/json" \
+  -d '{
+    "username": "admin",
+    "password": "admin123",
+    "role": "admin"
+  }'
+
+# Login to get a token
+curl -X POST http://localhost:8000/api/auth/login \
+  -H "Content-Type: application/x-www-form-urlencoded" \
+  -d "username=admin&password=admin123"
+```
+
+### Option B: Via Frontend
+
+1. The first time you access the app, you'll need to register via API first (as shown above)
+2. Then login through the frontend at http://localhost:3000/login
+
+## Step 5: Explore the API
+
+Use the interactive API documentation at:
+```
+http://localhost:8000/docs
+```
+
+Click "Authorize" and enter your token in the format:
+```
+Bearer YOUR_TOKEN_HERE
+```
+
+## Step 6: Test the API
+
+Run the test script to verify all endpoints:
+
+```bash
+./test_api.sh
+```
+
+Expected output:
+```
+===================================
+VelociCompanion API Test Script

+===================================
+```
+
+## Common Operations
+
+### Create a Host
+
+```bash
+# Get your token from login
+TOKEN="your_token_here"
+
+# Create a host
+curl -X POST http://localhost:8000/api/hosts \
+  -H "Authorization: Bearer $TOKEN" \
+  -H "Content-Type: application/json" \
+  -d '{
+    "hostname": "workstation-01",
+    "ip_address": "192.168.1.100",
+    "os": "Windows 10"
+  }'
+```
+
+### List Hosts
+
+```bash
+curl -X GET http://localhost:8000/api/hosts \
+  -H "Authorization: Bearer $TOKEN"
+```
+
+### Ingest Data
+
+```bash
+curl -X POST http://localhost:8000/api/ingestion/ingest \
+  -H "Authorization: Bearer $TOKEN" \
+  -H "Content-Type: application/json" \
+  -d '{
+    "hostname": "server-01",
+    "data": {
+      "artifact": "Windows.System.TaskScheduler",
+      "results": [...]
+    }
+  }'
+```
+
+## Troubleshooting
+
+### Database Connection Issues
+
+```bash
+# Check if database is running
+docker-compose logs db
+
+# Restart database
+docker-compose restart db
+```
+
+### Backend Not Starting
+
+```bash
+# Check backend logs
+docker-compose logs backend
+
+# Common issues:
+# - Database not ready: Wait a few seconds and check logs
+# - Port 8000 in use: Stop other services using that port
+```
+
+### Frontend Not Loading
+
+```bash
+# Check frontend logs
+docker-compose logs frontend
+
+# Rebuild frontend if needed
+docker-compose build frontend
+docker-compose up -d frontend
+```
+
+### Reset Everything
+
+```bash
+# Stop and remove all containers and volumes
+docker-compose down -v
+
+# Start fresh
+docker-compose up -d
+```
+
+## Next Steps
+
+1. **Create Additional Users**: Use the `/api/auth/register` endpoint
+2. **Set Up Tenants**: Create tenants via `/api/tenants` (admin only)
+3. **Integrate with Velociraptor**: Configure Velociraptor to send data to `/api/ingestion/ingest`
+4. **Explore Cases**: Create and manage threat hunting cases
+5. **Configure VirusTotal**: Set up VirusTotal API integration for hash lookups
+
+## Security Considerations
+
+⚠️ **Before deploying to production:**
+
+1. Change the `SECRET_KEY` in docker-compose.yml or .env file
+   - Must be at least 32 characters
+   - Use a cryptographically random string
+
+2. Use strong passwords for the database
+
+3. Enable HTTPS/TLS for API and frontend
+
+4. Configure proper firewall rules
+
+5. Review and update CORS settings in `backend/app/main.py`
+
+## Development Mode

+To run in development mode with hot reload:
+
+```bash
+# Backend
+cd backend
+python -m venv venv
+source venv/bin/activate
+pip install -r requirements.txt

-## Quick Start
+## Getting Started
 
-### Backend Setup
+### Prerequisites
+
+- Docker and Docker Compose
+- Python 3.11+ (for local development)
+- Node.js 18+ (for local development)
+
+### Quick Start with Docker
+
+1. Clone the repository:
+```bash
+git clone https://github.com/mblanke/ThreatHunt.git
+cd ThreatHunt
+```
+
+2. Start all services:
+```bash
+docker-compose up -d
+```
+
+3. Access the application:
+- Frontend: http://localhost:3000
+- Backend API: http://localhost:8000
+- API Documentation: http://localhost:8000/docs
+
+### Local Development
+
+#### Backend
 
 ```bash
 cd backend
-chmod +x setup_backend.sh
-./setup_backend.sh
-source venv/bin/activate
-python app.py
+python -m venv venv
+source venv/bin/activate  # On Windows: venv\Scripts\activate
+pip install -r requirements.txt
+
+# Set up environment variables
+cp .env.example .env
+# Edit .env with your settings
+
+# Run migrations
+alembic upgrade head
+
+# Start development server
+uvicorn app.main:app --reload
 ```
 
-### Frontend Setup
+#### Frontend
 
 ```bash
 cd frontend
 npm install
-npm run dev
+npm start
 ```
 
 ## API Endpoints
 
-- `GET /` - Serve React app
-- `GET /api/health` - Health check
-- `POST /api/upload` - File upload
-- `GET /api/analysis/<id>` - Get analysis results
+### Authentication
+- `POST /api/auth/register` - Register a new user
+- `POST /api/auth/login` - Login and receive JWT token
+- `GET /api/auth/me` - Get current user profile
+- `PUT /api/auth/me` - Update current user profile
 
-## Security Considerations
+### User Management (Admin only)
+- `GET /api/users` - List all users in tenant
+- `GET /api/users/{user_id}` - Get user by ID
+- `PUT /api/users/{user_id}` - Update user
+- `DELETE /api/users/{user_id}` - Deactivate user
 
-- File upload validation
-- Input sanitization
-- Rate limiting
-- CORS configuration
+### Tenants
+- `GET /api/tenants` - List tenants
+- `POST /api/tenants` - Create tenant (admin)
+- `GET /api/tenants/{tenant_id}` - Get tenant by ID
+
+### Hosts
+- `GET /api/hosts` - List hosts (scoped to tenant)
+- `POST /api/hosts` - Create host
+- `GET /api/hosts/{host_id}` - Get host by ID
+
+### Ingestion
+- `POST /api/ingestion/ingest` - Ingest data from Velociraptor
+
+### VirusTotal
+- `POST /api/vt/lookup` - Lookup hash in VirusTotal
+
+## Authentication Flow
+
+1. User registers or logs in via `/api/auth/login`
+2. Backend returns JWT token with user_id, tenant_id, and role
+3. Frontend stores token in localStorage
+4. All subsequent API requests include token in Authorization header
+5. Backend validates token and enforces tenant scoping
+
+## Multi-Tenancy
+
+- All data is scoped to tenant_id
+- Users can only access data within their tenant
+- Admin users have elevated permissions within their tenant
+- Cross-tenant access requires explicit permissions
+
+## Database Migrations
+
+Create a new migration:
+```bash
+cd backend
+alembic revision --autogenerate -m "Description of changes"
+```
+
+Apply migrations:
+```bash
+alembic upgrade head
+```
+
+Rollback migrations:
+```bash
+alembic downgrade -1
+```
+
+## Environment Variables
+
+### Backend
+- `DATABASE_URL` - PostgreSQL connection string
+- `SECRET_KEY` - Secret key for JWT signing (min 32 characters)
+- `ACCESS_TOKEN_EXPIRE_MINUTES` - JWT token expiration time (default: 30)
+
+### Frontend
+- `REACT_APP_API_URL` - Backend API URL (default: http://localhost:8000)
+
+## Security
+
+- Passwords are hashed using bcrypt
+- JWT tokens include expiration time
+- All API endpoints (except login/register) require authentication
+- Role-based access control for admin operations
+- Data isolation through tenant scoping
+
+## Testing
+
+### Backend
+```bash
+cd backend
+pytest
+```
+
+### Frontend
+```bash
+cd frontend
+npm test
+```
