3. **Basic health checking** - Add cluster connectivity validation
4. **Configuration templates** - Provide coordinator vs worker config examples

### Medium-term (Next Phase)
1. **Web UI Development** - Implement the missing `:8080/setup` interface
2. **SSH Deployment Module** - Add remote installation capabilities
3. **P2P Network Activation** - Enable automatic peer discovery
4. **Basic Key Management** - Implement simplified security model

### Long-term (Strategic)
1. **Full Plan Implementation** - Gradually implement all 7 phases
2. **Security Architecture** - Add Shamir's Secret Sharing and master keys
3. **Enterprise Features** - Leader election, DHT storage, model distribution
4. **Migration Path** - Allow upgrading from simple to sophisticated deployment

## Conclusion

Our enhanced installer successfully delivers **immediate functionality** for repository-based task coordination but represents a **significant simplification** of the original comprehensive plan. 

**Current State:** ✅ Single-node ready, repository integrated, immediately useful
**Original Vision:** 🔴 Enterprise-grade, security-first, fully distributed cluster

The implementation prioritizes **time-to-value** over **comprehensive architecture**. While this enables rapid deployment and testing, it means users must manually scale and manage clusters rather than having sophisticated automated deployment and management capabilities.

**Strategic Decision Point:** Continue with simplified approach for rapid iteration, or invest in implementing the full sophisticated architecture as originally planned.
