• Backup: Manual backup procedures, no automated backup solution

🔍 Areas for Investigation

• Memory Usage: Profile memory usage under load
• Startup Time: Optimize service startup time
• Resource Limits: Fine-tune systemd resource limits
• Caching: Investigate caching opportunities for better performance

Evolution of Project Decisions

Initial Decisions (Validated)

1. Nix Flakes: Chosen for modern Nix packaging - ✅ Successful
2. systemd Service: Chosen for NixOS integration - ✅ Successful
3. Security First: Comprehensive hardening from start - ✅ Successful
4. Single Data Directory: Simplified backup/restore - ✅ Successful

Evolved Decisions

1. Dependency Strategy: Started with nixpkgs-only, evolved to hybrid nixpkgs+pip approach
