+```
+
+## 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

+### Backend (.env)
+```bash
+DATABASE_URL=postgresql://user:strongpass@db-host:5432/velocicompanion
+SECRET_KEY=your-32-plus-character-secret-key-here-make-it-random
+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
+- **Database**: 4GB RAM minimum, 8GB+ for production
+- **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
+

+# 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)
+```
+

+
+## 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.

+```
+
+## 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
+===================================
+
+1. Testing health endpoint...
+✓ Health check passed
+
+2. Registering a new user...

+
+## 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

-# ThreatHunt - Analyst-Assist Threat Hunting Platform
+# VelociCompanion
 
-A modern threat hunting platform with integrated analyst-assist agent guidance. Analyze CSV artifact data exported from Velociraptor with AI-powered suggestions for investigation directions, analytical pivots, and hypothesis formation.
-
-## Overview
-
-ThreatHunt is a web application designed to help security analysts efficiently hunt for threats by:
-- Importing CSV artifacts from Velociraptor or other sources
-- Displaying data in an organized, queryable interface
-- Providing AI-powered guidance through an analyst-assist agent
-- Suggesting analytical directions, filters, and pivots
-- Highlighting anomalies and patterns of interest
-
-> **Agent Policy**: The analyst-assist agent provides read-only guidance only. It does not execute actions, escalate alerts, or modify data. All decisions remain with the analyst.
-
-## Quick Start
-
-### Docker (Recommended)
-
-```bash
-# Clone and navigate
-git clone https://github.com/mblanke/ThreatHunt.git
-cd ThreatHunt

-# Agent Types & Roles (Practical Taxonomy)
-
-Use this skill to choose the *right* kind of agent workflow for the job.
-
-## Common agent "types" (in practice)
-
-### 1) Chat assistant (no tools)
-Best for: explanations, brainstorming, small edits.
-Risk: can hallucinate; no grounding in repo state.
-
-### 2) Tool-using single agent
-Best for: well-scoped tasks where the agent can read/write files and run commands.
-Key control: strict DoD gates + minimal permissions.
-
-### 3) Planner + Executor (2-role pattern)
-Best for: medium complexity work (multi-file changes, feature work).
-Flow: Planner writes plan + acceptance criteria → Executor implements → Reviewer checks.
-
-### 4) Multi-agent (specialists)
-Best for: bigger features with separable workstreams (UI, backend, docs, tests).
-Rule: isolate context per role; use separate branches/worktrees.
-
-### 5) Supervisor / orchestrator
-Best for: long-running workflows with checkpoints (pipelines, report generation, PAD docs).
-Rule: supervisor delegates, enforces gates, and composes final output.
-
-## Decision rules (fast)
-- If you can describe it in ≤ 5 steps → single tool-using agent.
-- If you need tradeoffs/design → Planner + Executor.
-- If UI + backend + docs/tests all move → multi-agent specialists.
-- If it's a pipeline that runs repeatedly → orchestrator.
-
-## Guardrails (always)
-- DoD is the truth gate.
-- Separate branches/worktrees for parallel work.
-- Log decisions + commands in AGENT_LOG.md.

-## Checklist
-- Identify the **state** you're recomputing.
-- Add **memoization / caching** when the same subproblem repeats.
-- Prefer **linear scans** + caches over nested loops when possible.
-- If you can write it as a **recurrence**, you can test it.
-
-## Practical heuristics
-- Measure first when possible (timing + input sizes).
-- Optimize the biggest wins: avoid repeated I/O, repeated parsing, repeated network calls.
-- Keep caches bounded (size/TTL) and invalidate safely.
-- Choose data structures intentionally: dict/set for membership, heap for top-k, deque for queues.

-
-## The good
-- Rapid scaffolding and iteration
-- Fast UI prototypes
-- Quick exploration of architectures and options
-
-## The failure mode
-- "It works on my machine" code with weak tests
-- Security foot-guns (auth, input validation, secrets)
-- Performance cliffs (accidental O(n²), repeated I/O)
-- Unmaintainable abstractions
-
-## Safety rails (apply every time)
-- Always start with acceptance criteria (what "done" means).
-- Prefer small PRs; never dump a huge AI diff.
-- Require DoD gates (lint/test/build) before merge.
-- Write tests for behavior changes.
-- For anything security/data related: do a Reviewer pass.
-
-## When to slow down
-- Auth/session/token work
-- Anything touching payments, PII, secrets
-- Data migrations/schema changes
-- Performance-critical paths
-- "It's flaky" or "it only fails in CI"

-## Practical prompt pattern (use in PLAN)
-- "State assumptions, list files to touch, propose tests, and include rollback steps."

-# Performance Profiling (Bun/Node)
-
-Use this skill when:
-- a hot path feels slow
-- CPU usage is high
-- you suspect accidental O(n²) or repeated work
-- you need evidence before optimizing
-
-## Bun CPU profiling
-Bun supports CPU profiling via `--cpu-prof` (generates a `.cpuprofile` you can open in Chrome DevTools).
-
-Upcoming: `bun --cpu-prof-md <script>` outputs a CPU profile as **Markdown** so LLMs can read/grep it easily.
-
-### Workflow (Bun)
-1) Run the workload with profiling enabled
-   - Today: `bun --cpu-prof ./path/to/script.ts`
-   - Upcoming: `bun --cpu-prof-md ./path/to/script.ts`
-2) Save the output (or `.cpuprofile`) into `./profiles/` with a timestamp.
-3) Ask the Reviewer agent to:
-   - identify the top 5 hottest functions
-   - propose the smallest fix
-   - add a regression test or benchmark
-
-## Node CPU profiling (fallback)
-- `node --cpu-prof ./script.js` writes a `.cpuprofile` file.
-- Open in Chrome DevTools → Performance → Load profile.
-
-## Rules
-- Optimize based on measured hotspots, not vibes.
-- Prefer algorithmic wins (remove repeated work) over micro-optimizations.
-- Keep profiling artifacts out of git unless explicitly needed (use `.gitignore`).

-# Implementation Rules
-
-## Change policy
-- Prefer edits over rewrites.
-- Keep changes localized.
-- One change = one purpose.
-- Avoid unnecessary abstraction.
-
-## Dependency policy
-- Default: do not add dependencies.
-- If adding: explain why, alternatives considered, and impact.
-
-## Error handling
-- Validate inputs at boundaries.
-- Error messages must be actionable: what failed + what to do next.

-# Material UI (MUI) Design System
-
-Use this skill for any React/Next "portal/admin/dashboard" UI so you stay consistent and avoid random component soup.
-
-## Standard choice
-- Preferred UI library: **MUI (Material UI)**.
-- Prefer MUI components over ad-hoc HTML/CSS unless there's a good reason.
-- One design system per repo (do not mix Chakra/Ant/Bootstrap/etc.).
-
-## Setup (Next.js/React)
-- Install: `@mui/material @emotion/react @emotion/styled`
-- If using icons: `@mui/icons-material`
-- If using data grid: `@mui/x-data-grid` (or pro if licensed)
-
-## Theming rules
-- Define a single theme (typography, spacing, palette) and reuse everywhere.
-- Use semantic colors (primary/secondary/error/warning/success/info), not hard-coded hex everywhere.
-- Prefer MUI's `sx` for small styling; use `styled()` for reusable components.
-
-## "Portal" patterns (modals, popovers, menus)
-- Use MUI Dialog/Modal/Popover/Menu components instead of DIY portals.
-- Accessibility requirements:
-  - Focus is trapped in Dialog/Modal.
-  - Escape closes modal unless explicitly prevented.
-  - All inputs have labels; buttons have clear text/aria-labels.
-  - Keyboard navigation works end-to-end.
-
-## Layout conventions (for portals)
-- Use: AppBar + Drawer (or NavigationRail equivalent) + main content.
-- Keep pages as composition of small components: Page → Sections → Widgets.
-- Keep forms consistent: FormControl + helper text + validation messages.
-
-## Performance hygiene
-- Avoid re-render storms: memoize heavy lists; use virtualization for large tables (DataGrid).
-- Prefer server pagination for huge datasets.
-
-## PR review checklist
-- Theme is used (no random styling).
-- Components are MUI where reasonable.
-- Modal/popover accessibility is correct.
-- No mixed UI libraries.

-# MCP Server Design (Agent-First)
-
-Build MCP servers like you're designing a UI for a non-human user.
-
-This skill distills Phil Schmid's MCP server best practices into concrete repo rules.
-Source: "MCP is Not the Problem, It's your Server" (Jan 21, 2026).
-
-## 1) Outcomes, not operations
-- Do **not** wrap REST endpoints 1:1 as tools.
-- Expose high-level, outcome-oriented tools.
-  - Bad: `get_user`, `list_orders`, `get_order_status`
-  - Good: `track_latest_order(email)` (server orchestrates internally)
-
-## 2) Flatten arguments
-- Prefer top-level primitives + constrained enums.
-- Avoid nested `dict`/config objects (agents hallucinate keys).
-- Defaults reduce decision load.
-
-## 3) Instructions are context
-- Tool docstrings are *instructions*:
-  - when to use the tool
-  - argument formatting rules
-  - what the return means
-- Error strings are also context:
-  - return actionable, self-correcting messages (not raw stack traces)
-
-## 4) Curate ruthlessly
-- Aim for **5–15 tools** per server.
-- One server, one job. Split by persona if needed.
-- Delete unused tools. Don't dump raw data into context.
-
-## 5) Name tools for discovery
-- Avoid generic names (`create_issue`).
-- Prefer `{service}_{action}_{resource}`:
-  - `velociraptor_run_hunt`
-  - `github_list_prs`
-  - `slack_send_message`
-
-## 6) Paginate large results
-- Always support `limit` (default ~20–50).
-- Return metadata: `has_more`, `next_offset`, `total_count`.
-- Never return hundreds of rows unbounded.
-
-## Repo conventions
-- Put MCP tool specs in `mcp/` (schemas, examples, fixtures).
-- Provide at least 1 "golden path" example call per tool.
-- Add an eval that checks:
-  - tool names follow discovery convention
-  - args are flat + typed
-  - responses are concise + stable
-  - pagination works

-# FastMCP 3 Patterns (Providers + Transforms)
-
-Use this skill when you are building MCP servers in Python and want:
-- composable tool sets
-- per-user/per-session behavior
-- auth, versioning, observability, and long-running tasks
-
-## Mental model (FastMCP 3)
-FastMCP 3 treats everything as three composable primitives:
-- **Components**: what you expose (tools, resources, prompts)
-- **Providers**: where components come from (decorators, files, OpenAPI, remote MCP, etc.)
-- **Transforms**: how you reshape what clients see (namespace, filters, auth, versioning, visibility)
-
-## Recommended architecture for Marc's platform
-Build a **single "Cyber MCP Gateway"** that composes providers:
-- LocalProvider: core cyber tools (run hunt, parse triage, generate report)
-- OpenAPIProvider: wrap stable internal APIs (ticketing, asset DB) without 1:1 endpoint exposure
-- ProxyProvider/FastMCPProvider: mount sub-servers (e.g., Velociraptor tools, Intel feeds)
-
-Then apply transforms:
-- Namespace per domain: `hunt.*`, `intel.*`, `pad.*`
-- Visibility per session: hide dangerous tools unless user/role allows
-- VersionFilter: keep old clients working while you evolve tools
-
-## Production must-haves
-- **Tool timeouts**: never let a tool hang forever
-- **Pagination**: all list tools must be bounded
-- **Background tasks**: use for long hunts / ingest jobs
-- **Tracing**: emit OpenTelemetry traces so you can debug agent/tool behavior
-
-## Auth rules
-- Prefer component-level auth for "dangerous" tools.
-- Default stance: read-only tools visible; write/execute tools gated.
-
-## Versioning rules
-- Version your components when you change schemas or semantics.
-- Keep 1 previous version callable during migrations.
-
-## Upgrade guidance
-FastMCP 3 is in beta; pin to v2 for stability in production until you've tested.
