## 🚨 Known Issues

### Critical (Must Fix Before Production)
1. **Data Cross-Contamination** - Windows agent showing Linux updates
2. **Windows System Detection** - CPU model detection issues
3. **Windows User Experience** - Needs background service with tray icon

### Medium Priority
1. **Rate Limiting** - Missing security feature vs competitors
2. **Documentation** - Needs user guides and deployment instructions
3. **Error Handling** - Some edge cases need better user feedback

### Low Priority
1. **Private Registry Auth** - Docker private registries not supported
2. **CVE Enrichment** - Security vulnerability data integration missing
3. **Multi-arch Docker** - Limited multi-architecture support
4. **Unit Tests** - Need comprehensive test coverage

## 🔄 Deferred Features Analysis

### Features Identified in Initial Analysis

The following features were identified as deferred during early development planning:

1. **CVE Enrichment Integration**
   - **Planned Integration**: Ubuntu Security Advisories and Red Hat Security Data APIs
   - **Current Status**: Database schema includes `cve_list` fields, but no active enrichment
   - **Complexity**: Requires API integration, rate limiting, and data mapping
   - **Priority**: Low - would be valuable for security-focused users

2. **Private Registry Authentication**
   - **Planned Support**: Basic auth, custom tokens for Docker private registries
   - **Current Status**: Agent gracefully fails on private images
   - **Complexity**: Requires secure credential management and registry-specific logic
   - **Priority**: Low - affects enterprise users with private registries

3. **Rate Limiting Implementation**
   - **Security Gap**: Missing vs competitors like PatchMon
   - **Current Status**: Framework in place but no active rate limiting
   - **Complexity**: Requires configurable limits and Redis integration
   - **Priority**: Medium - important for production security

### Current Implementation Status

**CVE Support**:
- ✅ Database models include CVE list fields
- ✅ Terminal display can show CVE information
- ❌ No active CVE data enrichment from security APIs
- ❌ No severity scoring based on CVE data

**Private Registry Support**:
- ✅ Error handling prevents false positives
- ✅ Works with public Docker Hub images
- ❌ No authentication mechanism for private registries
- ❌ No support for custom registry configurations

**Rate Limiting**:
- ✅ JWT authentication provides basic security
- ✅ Request logging available
- ❌ No rate limiting middleware implemented
- ❌ No DoS protection mechanisms

### Implementation Challenges

**CVE Enrichment**:
- Requires API keys for Ubuntu/Red Hat security feeds
- Rate limiting on external security APIs
- Complex mapping between package versions and CVE IDs
- Need for caching to avoid repeated API calls

**Private Registry Auth**:
- Secure storage of registry credentials
- Multiple authentication methods (basic, bearer, custom)
- Registry-specific API variations
- Error handling for auth failures

**Rate Limiting**:
- Need Redis or similar for distributed rate limiting
- Configurable limits per endpoint/user
- Graceful degradation under high load
- Integration with existing JWT authentication
