## Critical Path Items (Must Complete First)

### **Phase 1 Critical Path**
1. **OSBuild Architecture Analysis** - Must understand current system before modifying
2. **debos Integration Planning** - Must plan how to integrate Debian logic
3. **Technical Specifications** - Must have clear plan before implementation

### **Phase 2 Critical Path**
1. **Debian Package Management** - Core functionality required for everything else
2. **OSTree Composition** - Essential for atomic functionality
3. **Build Environment Integration** - Required for package building

### **Phase 3 Critical Path**
1. **Build Orchestration** - Required for managing multiple builds
2. **Environment Management** - Required for build isolation and resource management

### **Phase 4 Critical Path**
1. **System Integration** - Must connect all components
2. **Image Generation** - Core output functionality
3. **Performance Optimization** - Required for production use

### **Phase 5 Critical Path**
1. **Web Interface** - Required for user interaction
2. **Security Hardening** - Required for production deployment
3. **Documentation** - Required for adoption and maintenance

## Risk Mitigation

### **Technical Risks**
- **OSBuild Complexity**: Start with simple modifications, build complexity gradually
- **Integration Challenges**: Use well-defined interfaces, test integration points early
- **Performance Issues**: Test performance early, optimize continuously
- **Compatibility Issues**: Test with real Debian packages, validate edge cases

### **Timeline Risks**
- **Scope Creep**: Stick to core functionality, defer advanced features
- **Integration Delays**: Plan integration carefully, test early and often
- **Testing Complexity**: Start testing early, automate testing where possible
- **Documentation**: Document as you go, don't leave it until the end

### **Resource Risks**
- **Developer Availability**: Plan for developer rotation, document everything
- **Infrastructure Issues**: Use simple infrastructure initially, scale gradually
- **Dependency Changes**: Monitor upstream projects, plan for changes

## Next Immediate Actions (This Week)

## Notes

- **Priority**: Focus on core functionality first, add advanced features later
- **Testing**: Test each component individually before integration
- **Documentation**: Document everything as you go, don't assume you'll remember
- **Iteration**: Use iterative development, get working system early and improve gradually
- **Community**: Engage with Debian community early for feedback and adoption
