fix: update compose submodule to pick up backup network fix

The backup_stack.service was failing because the deployed compose.yml
still had backup_net declared as external: true, but the network was
never created externally.

PR #45 on the compose repo (d7449e9) already fixed this by changing
to driver: bridge, but the infra submodule was still pinned to a
pre-fix commit.

This updates assets/compose to d7449e9 so the next nixos-rebuild
switch deploys the fix.

+# NixOS Infrastructure with AI Assistant
+
+## What This Is
+
+This project manages a NixOS-based infrastructure with Docker services, integrated with OpenCode AI assistant for automated management. The system supports:
+
+- Reproducible NixOS infrastructure configuration
+- Docker service management via Docker Compose
+- AI-assisted infrastructure operations
+- Automatic service deployment and lifecycle management
+- Integration with existing Docker stacks (ai, cloudstorage, homeautomation, network, passwordmanager, versioncontrol)
+
+## Core Value
+
+The core value is a **reproducible and evolvable NixOS infrastructure** that can be managed through natural language interactions with the OpenCode AI assistant. The system should automatically detect and integrate new Docker services while maintaining consistency across all deployments.
+
+## Requirements
+
+### Validated
+
+- NixOS configuration management with flakes
+- Docker service integration via docker_manager.nix
+- Traefik reverse proxy with automatic TLS certificates
+- Environment variable management via agenix secrets
+- Standardized service patterns across all Docker stacks
+
+### Active
+
+- [ ] Automatic detection and integration of new Docker Compose files in `assets/compose/`
+- [ ] AI assistant integration for service lifecycle management
+- [ ] Service health monitoring and logging verification
+- [ ] Documentation of integration patterns in SKILL.md
+- [ ] Automated system update workflow (`nh os switch`)
+
+### Out of Scope
+
+- Full n8n integration for automated workflows - deferring to future milestone
+- Self-healing infrastructure with automatic problem detection - future enhancement
+- Multi-host orchestration - single-host focus for v1
+
+## Key Decisions
+
+| Decision | Rationale | Outcome |
+|----------|-----------|---------|
+| NixOS with Flakes | Reproducible infrastructure, better dependency management | Good |
+| Docker Compose integration | Preserves existing service configurations, flexibility | Good |
+| agenix for secrets | Secure secrets management, Nix native integration | Good |
+| Traefik reverse proxy | Unified HTTPS entrypoint, automatic certificate management | Good |
+| Standardized service patterns | Consistency across services, easier maintenance | Pending |
+
+## Context
+
+- **Existing Services**: ai (Llama.cpp, Open WebUI, n8n), cloudstorage (Nextcloud), homeautomation (Home Assistant), network (Traefik, DDNS), passwordmanager (Vaultwarden), versioncontrol (Gitea)
+- **Tech Stack**: NixOS unstable, Docker, Docker Compose, Traefik, agenix, OpenCode AI
+- **Hardware**: AMD MI50 GPUs for AI workloads
+- **Network**: Traefik-net bridge network for all services
+- **Storage**: `/mnt/HoardingCow_docker_data/<service>` for persistent data

+| Mobile client availability | ✅ | ✅ | ✅ |
+
+## Recommendation
+
+**OpenTAKServer (OTS)** is the optimal choice for this implementation for the following reasons:
+
+1. **Comprehensive Feature Set**: OTS offers the most complete feature set including video streaming, advanced authentication (2FA, LDAP, certificates), and integration with multiple data sources (ADS-B, AIS).
+
+2. **Excellent Web Interface**: OTS provides a modern, feature-rich web UI with live mapping capabilities that exceed both FTS and the TAK Product Center server.
+
+3. **Easy Deployment**: OTS offers installation scripts for multiple platforms (Ubuntu, Raspberry Pi, Windows, macOS) and Docker support, making it ideal for the NixOS infrastructure.
+
+4. **Active Development**: The project is actively maintained with recent releases (Dec 2025) and ongoing feature development.
+
+5. **Scalability**: Designed to run on both servers and single-board computers, making it flexible for different deployment scenarios.
+
+6. **Integration Capabilities**: Supports REST API, WebSockets, and multiple authentication methods for seamless integration with existing infrastructure.
+
+### Runner-Up: FreeTAKServer (FTS)
+
+FTS is a strong alternative with excellent community support and documentation. It would be suitable if:
+- Simpler deployment is preferred
+- Extensive REST API usage is planned
+- Production-ready status is a priority
+
+### Not Recommended: TAK Product Center Server
+
+While this is the official implementation, it lacks critical features for this use case:
+- No web interface
+- Limited documentation
+- Complex deployment requirements
+- Designed primarily for DoD environments
+- No clear Docker deployment path
+
+## Implementation Plan
+
+### Deployment Strategy
+
+1. **Containerized Deployment**: Use the official OpenTAKServer Docker image for easy integration with existing Traefik reverse proxy.
+
+2. **Configuration**: 
+   - Configure LDAP authentication for integration with existing user directory
+   - Set up SSL/TLS for secure connections
+   - Configure groups/channels for team organization
+   - Enable video streaming integration if needed
+
+3. **Integration**:
+   - Add to docker_manager.nix module
+   - Configure Traefik routing with automatic TLS
+   - Set up persistent storage for CoT messages and media
+   - Integrate with existing monitoring and logging systems
+
+4. **Testing**:
+   - Verify COT protocol connectivity from ATAK/iTAK/WinTAK clients
+   - Test web interface functionality
+   - Validate authentication and authorization
+   - Confirm geospatial mapping features work correctly
+
+### Configuration Requirements
+
+- **Docker**: Official OTS Docker image
+- **Network**: TCP ports for COT protocol and web interface
+- **Storage**: Persistent volumes for CoT data and media files
+- **Dependencies**: RabbitMQ (can be co-located)
+- **Authentication**: LDAP or Active Directory integration
+- **TLS**: Let's Encrypt certificates via Traefik
+
+### Timeline Estimate
+
+- **Research Completion**: Immediate (this report)
+- **Decision Finalized**: Ready for approval
+- **Implementation Ready**: After decision approval
+- **Deployment**: 1-2 weeks after approval
+
+## Risk Assessment
+
+### Risks
+
+1. **License Compatibility**: GPL-3.0 license may require careful consideration for integration with other components.
+
+2. **Resource Requirements**: OTS has higher resource requirements than FTS, particularly with RabbitMQ.
+
+3. **Complexity**: More features mean more configuration complexity.
+
+### Mitigation Strategies
+
+1. **License**: Review GPL-3.0 compatibility with existing infrastructure components.
+
+2. **Resources**: Monitor resource usage and scale accordingly. Consider separating RabbitMQ into its own container.
+
+3. **Complexity**: Use configuration management (Nix) to handle complex setup, reducing manual configuration errors.
+
+## Conclusion
+
+OpenTAKServer (OTS) is the recommended solution for implementing TAK server functionality in the NixOS infrastructure. It provides the best balance of features, ease of deployment, and ongoing maintenance. The implementation can proceed with confidence in the solution's capability to meet all requirements for team coordination and offsite operator integration.
+
+## Next Steps
+
+1. Approve the selection of OpenTAKServer
+2. Begin Phase 6 implementation planning
+3. Create Docker Compose configuration for OTS
+4. Set up persistent storage requirements
+5. Integrate with docker_manager.nix module
+6. Configure Traefik routing and TLS
+7. Test COT protocol functionality

+# Phase 6: TAK Server Implementation
+
+## Goal
+Implement the selected TAK-compatible server as a Docker service integrated with the existing NixOS infrastructure.
+
+## Dependencies
+- Phase 5: TAK Server Research & Selection completed
+- Selected TAK implementation identified
+- Research report with configuration details
+
+## Implementation Plan
+
+### 1. Docker Compose Configuration
+
+Create `/home/gortium/infra/assets/compose/tak/compose.yml` following existing patterns:
+
+```yaml
+version: "3.8"
+services:
+  tak-server:
+    image: [selected-image]
+    container_name: tak-server
+    restart: unless-stopped
+    networks:
+      - traefik-net
+    environment:
+      - [required-env-vars]
+    volumes:
+      - [data-volume-mounts]
+    labels:
+      - "traefik.enable=true"
+      # HTTP router with redirect
+      - "traefik.http.routers.tak-http.rule=Host(`tak.lazyworkhorse.net`)"
+      - "traefik.http.routers.tak-http.entrypoints=web"
+      - "traefik.http.routers.tak-http.middlewares=redirect-to-https"
+      # HTTPS router with TLS
+      - "traefik.http.routers.tak-https.rule=Host(`tak.lazyworkhorse.net`)"
+      - "traefik.http.routers.tak-https.entrypoints=websecure"
+      - "traefik.http.routers.tak-https.tls=true"
+      - "traefik.http.routers.tak-https.tls.certresolver=njalla"
+      # Service configuration
+      - "traefik.http.services.tak.loadbalancer.server.port=[service-port]"
+
+networks:
+  traefik-net:
+    external: true
+```
+
+### 2. Service Integration
+
+Update `/home/gortium/infra/hosts/lazyworkhorse/configuration.nix` to include TAK service in the `services.dockerStacks` section:
+
+```nix
+services.dockerStacks = {
+  versioncontrol = {
+    path = self + "/assets/compose/versioncontrol";
+    ports = [ 2222 ];
+  };
+
+  network = {
+    path = self + "/assets/compose/network";
+    envFile = config.age.secrets.containers_env.path;
+    ports = [ 80 443 ];
+  };
+
+  passwordmanager = {
+    path = self + "/assets/compose/passwordmanager";
+  };
+
+  ai = {
+    path = self + "/assets/compose/ai";
+    envFile = config.age.secrets.containers_env.path;
+  };
+
+  cloudstorage = {
+    path = self + "/assets/compose/cloudstorage";
+    envFile = config.age.secrets.containers_env.path;
+  };
+
+  homeautomation = {
+    path = self + "/assets/compose/homeautomation";
+    envFile = config.age.secrets.containers_env.path;
+  };
+
+  tak = {
+    path = self + "/assets/compose/tak";
+    ports = [ [service-port] ];
+  };
+};
+```
+
+The integration follows the existing pattern used for other Docker services, directly in the host configuration rather than through a separate module.
+
+### 3. Persistent Storage
+
+Set up persistent storage volume:
+- Location: `/mnt/HoardingCow_docker_data/TAK/`
+- Subdirectories: `data`, `config`, `logs`
+- Permissions: Read/write for TAK service user
+
+### 4. Environment Configuration
+
+Create environment file for sensitive configuration:
+- Database credentials (if applicable)
+- Authentication secrets
+- API keys
+- Encryption keys
+
+### 5. Firewall Configuration
+
+Update firewall to allow required ports:
+- TAK service port (typically 8080)
+- WebSocket port if separate
+- Any additional required ports
+
+## Testing Plan
+
+### Basic Functionality
+1. Verify container starts successfully
+2. Test web interface accessibility

+3. User authentication (if applicable)
+4. Message persistence
+
+### Integration Tests
+1. Verify with existing Docker services
+2. Test network connectivity
+3. Validate firewall rules
+4. Confirm logging and monitoring
+
+## Rollback Plan
+
+If implementation issues arise:
+1. Stop TAK service: `systemctl stop tak_stack`
+2. Remove containers: `docker-compose down`
+3. Revert configuration changes
+4. Review logs and diagnostics
+5. Address issues before retry
+
+## Documentation Requirements
+
+1. **Configuration Guide**
+   - Environment variables
+   - Volume mounts
+   - Port mappings
+   - Firewall requirements
+
+2. **Usage Guide**
+   - Web interface access

+# AI Worker Restricted Access
+
+This module provides SSH access for the AI worker (hermes-agent) to run ollama benchmarks on the host.
+
+## Security Model
+
+The `ai-worker` user has:
+
+### Filesystem Access
+- **Home directory**: `/home/ai-worker` (standard user home)
+- **No bind mounts**: Cannot access `/home/gortium/infra` or other host files
+- **Cannot access**: Any files outside standard system paths
+
+### Sudo Access
+- **NONE**: ai-worker has no sudo privileges
+- Cannot run `nh`, `nixos-rebuild`, `nixpkgs-fmt`, or `nix` with elevated permissions
+
+### Docker Access
+- Member of `docker` group - can run `docker` and `docker exec` commands
+- Primary use: `docker exec ollama ollama ...` for benchmarking
+- Can run `docker exec --privileged ollama rocm-smi ...` for VRAM monitoring
+
+## Workflow: SSH + Docker Benchmarking
+
+The AI worker connects from the Hermes container to the host via SSH, runs ollama benchmarks, then returns to save results.
+
+### Example Workflow
+
+```bash
+# From Hermes container, SSH to host
+ssh -i /path/to/ssh/key ai-worker@host.docker.internal
+
+# On host, run ollama benchmarks via docker
+docker exec ollama ollama pull devstral-small-2:24b
+
+# Create test modelfile
+docker exec ollama bash -c 'cat <<EOF > /root/.ollama/test.modelfile
+FROM devstral-small-2:24b
+PARAMETER num_ctx 65536
+PARAMETER num_gpu 99
+PARAMETER flash_attn true
+EOF'
+
+# Create and test model
+docker exec ollama ollama create test-model -f /root/.ollama/test.modelfile
+docker exec ollama ollama run test-model "Write a Python async function"
+
+# Check VRAM usage
+docker exec --privileged ollama rocm-smi --showmeminfo vram
+
+# Cleanup
+docker exec ollama ollama rm test-model
+
+# Exit SSH, return to Hermes container
+exit
+
+# Save results in Hermes container
+# /opt/data/ai-optimizer/state.json
+# /opt/data/ai-optimizer/results.csv
+```
+
+## SSH Access
+
+Connect as:
+```bash
+ssh ai-worker@lazyworkhorse
+```
+
+The working directory will be `/home/ai-worker`. No infra repo access.
+
+## Verification
+
+Check ai-worker permissions:
+```bash
+# On the host, as root or gortium:
+sudo -u ai-worker sudo -l
+# Should show: no sudo access
+
+# Check docker group membership
+groups ai-worker
+# Should show: ai-worker docker
+```
+
+## Troubleshooting
+
+If ai-worker cannot run docker commands:
+```bash
+# Check docker group membership
+groups ai-worker
+
+# Verify ollama container is running
+docker ps | grep ollama
+
+# Test docker access
+sudo -u ai-worker docker exec ollama ollama list
+```
+
+If SSH connection fails:
+```bash
+# Check SSH key is authorized
+cat /home/ai-worker/.ssh/authorized_keys
+
+# Check SSH service
+systemctl status sshd
+```
