docs: initialize NixOS Infrastructure with AI Assistant (4 phases)

Reproducible NixOS infrastructure with Docker service management and AI assistant integration.

Phases:
1. Foundation Setup: Core NixOS configuration with flakes
2. Docker Service Integration: Docker Compose integration and Traefik proxy
3. AI Assistant Integration: OpenCode AI assistant for infrastructure management
4. Automation & Monitoring: Service detection and health monitoring

+# Roadmap: NixOS Infrastructure with AI Assistant
+
+## Overview
+
+This roadmap outlines the implementation of a reproducible NixOS infrastructure with Docker service management, integrated with an AI assistant for automated operations. The system will automatically detect and integrate new Docker services while maintaining consistency across deployments.
+
+## Domain Expertise
+
+None
+
+## Phases
+
+- [ ] **Phase 1: Foundation Setup** - Establish core NixOS configuration with flakes
+- [ ] **Phase 2: Docker Service Integration** - Integrate Docker Compose services
+- [ ] **Phase 3: AI Assistant Integration** - Enable AI-assisted infrastructure management
+- [ ] **Phase 4: Automation & Monitoring** - Implement service detection and monitoring
+
+## Phase Details
+
+### Phase 1: Foundation Setup
+**Goal**: Establish the core NixOS configuration with flakes and basic infrastructure
+**Depends on**: Nothing (first phase)
+**Research**: Unlikely (established Nix patterns)
+**Plans**: 3 plans
+
+Plans:
+- [ ] 01-01: Set up NixOS flake structure with hardware configuration
+- [ ] 01-02: Configure basic services and networking
+- [ ] 01-03: Implement secrets management with agenix
+
+### Phase 2: Docker Service Integration
+**Goal**: Integrate Docker service management with Traefik reverse proxy
+**Depends on**: Phase 1
+**Research**: Unlikely (existing Docker Compose patterns)
+**Plans**: 3 plans
+
+Plans:
+- [ ] 02-01: Implement docker_manager.nix for service integration
+- [ ] 02-02: Configure Traefik reverse proxy with automatic TLS
+- [ ] 02-03: Set up persistent storage for Docker services
+
+### Phase 3: AI Assistant Integration
+**Goal**: Enable AI assistant to manage infrastructure operations
+**Depends on**: Phase 2
+**Research**: Likely (AI integration patterns)
+**Research topics**: OpenCode AI API, infrastructure management patterns, natural language parsing for service operations
+**Plans**: 2 plans
+
+Plans:
+- [ ] 03-01: Integrate OpenCode AI assistant with NixOS configuration
+- [ ] 03-02: Implement natural language command parsing
+
+### Phase 4: Automation & Monitoring
+**Goal**: Implement automatic service detection and health monitoring
+**Depends on**: Phase 3
+**Research**: Unlikely (internal patterns)
+**Plans**: 2 plans
+
+Plans:
+- [ ] 04-01: Implement automatic Docker Compose file detection
+- [ ] 04-02: Add service health monitoring and logging
+
