+# 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. Validate Traefik routing and TLS
+4. Confirm persistent storage working
+
+### Core Features
+1. COT message transmission/reception
+2. Geospatial mapping functionality
+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
+   - COT protocol usage
+   - Geospatial features
+   - Authentication (if applicable)
+
+3. **Troubleshooting**
+   - Common issues
+   - Log locations
+   - Diagnostic commands
+
+## Timeline

+- Configuration complete: [Estimated date]
+- Testing completed: [Estimated date]
+- Ready for validation: [Estimated date]
+- Move to Phase 7: [Estimated date]
+
+## Notes
+
+- Follow existing patterns from other services (n8n, Bitwarden, etc.)
+- Ensure proper Traefik integration with existing middleware
+- Document all configuration decisions
+- Test thoroughly before moving to validation phase

 - **Build/Deploy:** Use `nixos-rebuild switch --flake .#<hostname>` to build and deploy the configuration for a specific host.
+- **CRITICAL — Validate before pushing:** Always `nix build --no-link '.#nixosConfigurations.<hostname>.config.system.build.toplevel'` (or `nh os build`) and confirm it succeeds before pushing any changes. Never push untested NixOS configs.

+# 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
+```
