+# 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
+

+---
+
+## Why Nix in a Container?
+
+The Hermes Agent container runs on an Ubuntu/Debian base. To deploy NixOS
+configurations to remote hosts, we need:
+
+- `nix` — the Nix package manager (for building configurations)
+- `nixos-rebuild` — the NixOS deployment tool
+- Access to the infra repo with flake configuration
+
+Installing Nix inside the container avoids:
+- Host-level Nix installation on the Docker host
+- Cross-container volume mounts of /nix/store
+- Dependencies on the host's Nix daemon (which may be a different version)
+
+## Prerequisites
+
+- Docker host running Linux (x86_64 and/or aarch64)
+- Container base: Debian/Ubuntu (apt-based)
+- 1-2 GB additional disk space for Nix store
+- Network access to cache.nixos.org (or a local binary cache)
+- Git access to the infra repository
+
+## Installation Methods
+
+### Method A: Determinate Systems Installer (Recommended)
+
+The Determinate Systems installer is the recommended approach. It is non-interactive,
+sets up flakes by default, and handles multi-user installation cleanly.
+
+**Dockerfile additions:**
+
+```dockerfile
+# Install Nix (Determinate Systems installer)
+RUN apt-get update && apt-get install -y --no-install-recommends \
+    curl \
+    xz-utils \
+    && rm -rf /var/lib/apt/lists/*
+
+# Download and run Nix installer (non-interactive)
+RUN curl --proto '=https' --tlsv1.2 -sSf -L https://install.determinate.systems/nix \
+    -o /tmp/nix-install.sh \
+    && chmod +x /tmp/nix-install.sh \
+    && sh /tmp/nix-install.sh install --no-confirm \
+    && rm /tmp/nix-install.sh
+
+# Configure Nix for flakes
+RUN mkdir -p /root/.config/nix \
+    && echo 'experimental-features = nix-command flakes' > /root/.config/nix/nix.conf
+
+# Add Nix to PATH for all users
+ENV PATH="/nix/var/nix/profiles/default/bin:$PATH"
+```
+
+**Pros:**
+- Fully non-interactive (--no-confirm)
+- Enables flakes automatically
+- Sets up multi-user daemon
+- Auto-selects correct architecture
+- Handles upgrades gracefully
+
+**Cons:**
+- Downloads ~100 MB installer
+- Requires systemd in container (works with --privileged or cgroupv2)
+- Daemon mode may conflict with container exit semantics
+
+**Container runtime additions:**
+
+For the Nix daemon to work properly inside a container, you may need:
+```dockerfile
+# Ensure /nix is a volume for persistence
+VOLUME /nix
+
+# Or mount tmpfs for ephemeral builds:
+# docker run --tmpfs /nix:exec,size=4G ...
+```
+
+### Method B: Vanilla Nix Installer
+
+The official single-user Nix installer is lighter but requires manual flake setup.
+
+**Dockerfile additions:**
+
+```dockerfile
+# Install Nix (single-user, official installer)
+RUN apt-get update && apt-get install -y --no-install-recommends \
+    curl \
+    sudo \
+    xz-utils \
+    && rm -rf /var/lib/apt/lists/*
+
+# Install Nix as root (single-user)
+RUN curl -L https://nixos.org/nix/install -o /tmp/nix-install.sh \
+    && chmod +x /tmp/nix-install.sh \
+    && sh /tmp/nix-install.sh --no-daemon \
+    && rm /tmp/nix-install.sh
+
+# Enable flakes
+RUN mkdir -p /root/.config/nix \
+    && echo 'experimental-features = nix-command flakes' > /root/.config/nix/nix.conf
+
+# Source Nix in shell
+RUN echo '. /root/.nix-profile/etc/profile.d/nix.sh' >> /root/.bashrc
+ENV PATH="/root/.nix-profile/bin:$PATH"
+```
+
+**Pros:**
+- Smaller installer
+- No daemon needed (single-user mode)
+- Works in containers without systemd
+- Simpler container lifecycle
+
+**Cons:**
+- Manual flake configuration required
+- Single-user only (no multi-user isolation)
+- PATH must be set manually
+- No automatic garbage collection
+
+### Method C: NixOS-Based Container Image
+
+For maximum isolation, use an official NixOS base image for the build stage.
+
+**Multi-stage Dockerfile:**
+
+```dockerfile
+# Build stage: NixOS builder
+FROM nixos/nix:latest AS builder
+
+COPY infra /infra
+WORKDIR /infra
+
+# Build the configuration once
+RUN nix build '.#nixosConfigurations.lazyworkhorse.config.system.build.toplevel'
+
+# Final stage: Hermes container
+FROM ubuntu:22.04
+
+# Copy the Nix closure and binary cache
+COPY --from=builder /nix /nix
+
+# ... rest of Hermes setup
+```
+
+**Pros:**
+- Purely declarative build environment
+- No installation at runtime
+- Easy to pin Nix version
+- Good for CI/CD pipelines
+
+**Cons:**
+- Requires multi-stage Docker build
+- Larger initial image build
+- Harder to update Nix version at runtime
+- Overkill if Nix is only needed for `nixos-rebuild`

+
+## Architecture-Specific Notes
+
+### x86_64 (lazyworkhorse)
+
+The Hermes container likely runs on x86_64 hardware for the primary server.
+Nix will download x86_64 binaries from cache.nixos.org by default.
+
+**No special configuration needed** — the standard installer works out of the box.
+
+If the container is running on an AMD Ryzen/EPYC or Intel Xeon, consider:
+```bash
+# Enable CPU-specific optimizations (optional)
+echo 'extra-platforms = x86_64-v1 x86_64-v2 x86_64-v3' >> /root/.config/nix/nix.conf
+```
+
+### aarch64 (cyt-pi, uConsole)
+
+When building for aarch64 targets from an x86_64 container, you need either:
+1. Remote builder (aarch64 machine does the build), or
+2. QEMU-based emulation (slower but self-contained), or
+3. Build directly on the aarch64 target using `--build-host`
+
+**For QEMU emulation in the container:**
+
+```dockerfile
+# Enable binfmt for aarch64 emulation
+RUN apt-get update && apt-get install -y --no-install-recommends \
+    qemu-user-static \
+    binfmt-support \
+    && rm -rf /var/lib/apt/lists/*
+
+# Register aarch64 binfmt
+RUN update-binfmts --enable qemu-aarch64
+```
+
+**Container runtime (for QEMU):**
+```bash
+docker run --privileged --rm ... hermes-agent
+# Or with specific capability:
+docker run --cap-add=SYS_ADMIN --security-opt seccomp=unconfined ... hermes-agent
+```
+
+### Cross-Compilation
+
+For native cross-compilation (without emulation), add to your Nix configuration:
+
+```nix
+# In your flake.nix or nix.conf
+{
+  nix.settings.extra-platforms = [ "aarch64-linux" "x86_64-linux" ];
+  nix.settings.extra-sandbox-paths = [ ];
+  boot.binfmt.emulatedSystems = [ "aarch64-linux" ];
+}
+```
+
+Or in `nix.conf`:
+```
+extra-platforms = x86_64-linux aarch64-linux
+extra-sandbox-paths =
+```
+
+---
+
+## Post-Install Configuration
+
+### nix.conf for Container Usage
+
+Recommended `/root/.config/nix/nix.conf`:
+
+```ini
+experimental-features = nix-command flakes
+substituters = https://cache.nixos.org/
+trusted-users = root
+max-jobs = auto
+cores = 0
+sandbox = false
+```
+
+Note: `sandbox = false` is needed inside containers that lack full sandbox
+support. This is safe in a single-tenant container environment.
+
+### PATH Setup
+
+Add to your Dockerfile:
+```dockerfile
+ENV PATH="/nix/var/nix/profiles/default/bin:/root/.nix-profile/bin:${PATH}"
+```
+
+### Shell Integration
+
+```dockerfile
+RUN echo 'source /root/.nix-profile/etc/profile.d/nix.sh' >> /root/.bashrc
+```
+
+---
+
+## Verification
+
+After installation, verify with:
+
+```bash
+# Check Nix is available
+nix --version
+
+# Check nixos-rebuild
+nixos-rebuild --help | head -3
+
+# Verify flakes are enabled
+nix flake --help
+
+# Test a build (must be in infra repo)
+cd /opt/data/infra
+nix build --no-link '.#nixosConfigurations.lazyworkhorse.config.system.build.toplevel'
+
+# Check available systems
+nix eval --impure --expr 'builtins.currentSystem'
+```
+
+---
+
+## Container-Specific Considerations
+
+### Persistence
+
+The `/nix` directory should be a Docker volume to avoid re-downloading
+packages on every container restart:
+
+```yaml
+# docker-compose.yml
+volumes:
+  - nix-store:/nix
+
+volumes:
+  nix-store:
+```
+
+Without persistence, every container restart requires re-downloading the
+entire Nix store (~500 MB - 2 GB depending on packages used).
+
+### Disk Space
+
+The Nix store grows over time as old generations accumulate. Set up garbage
+collection:
+
+```bash
+# Manual GC
+nix store gc
+
+# Remove old generations
+nix-collect-garbage --delete-older-than 30d
+
+# Automatic GC (in nix.conf)
+# Currently not supported in nix.conf, but you can run a cron job:
+# nix store gc --max 10G
+```
+
+In Docker, limit store growth with:
+```dockerfile
+# Configure max store size
+RUN mkdir -p /etc/nix && \
+    echo 'min-free = 5368709120' > /etc/nix/nix.conf  # Keep 5GB free
+```
+
+### Security
+
+Running Nix in a container introduces some security considerations:
+
+1. **Sandboxing:** `sandbox = false` disables build isolation. In a multi-tenant
+   container, this means Nix builds can affect the container filesystem.
+   **Mitigation:** Only build configs you trust (your own infra repo).
+
+2. **Network access:** The container needs outbound access to cache.nixos.org.
+   If using a restricted network, set up a local binary cache:
+   ```nix
+   substituters = https://cache.nixos.org/ https://nix-cache.internal/
+   ```
+
+3. **Privileged mode:** QEMU emulation for aarch64 builds may need `--privileged`
+   or `--security-opt seccomp=unconfined`. This reduces container isolation.
+   **Mitigation:** Use remote builders or build natively on the target.
+
+4. **Supply chain:** Nix derivations pin exact inputs via hashes. Verify
+   flake.lock is committed and reviewed.
+
+### Resource Constraints
+
+Nix builds can be memory and CPU intensive:
+
+```nix
+# Limit build parallelism in nix.conf
+max-jobs = 2
+cores = 4
+
+# Or set per-build:
+# nix build --max-jobs 2 --cores 4
+```
+
+For containers with limited memory (< 2 GB), consider:
+- Building on the target host instead (`--build-host`)
+- Using the deploy script's `build` action separately
+
+---
+
+## Integration with deploy.sh
+
+The deployment script at `scripts/deploy.sh` expects:
+
+1. **Nix installed** with flakes enabled
+2. **SSH key** at `/opt/data/home/.ssh/id_hermes_gitea` (or via SSH_KEY env)
+3. **Infra repo** cloned at the script's parent directory
+4. **Network access** to:
+   - `code.lazyworkhorse.net:2222` (Gitea for git operations)
+   - Target hosts via SSH (see deploy-ssh-config)
+   - `cache.nixos.org` or a local substitute
+
+Typical usage from Hermes:
+
+```bash
+# Full deployment
+./scripts/deploy.sh lazyworkhorse master switch
+
+# Build-only check (no remote deployment)
+./scripts/deploy.sh cyt-pi master build
+
+# Dry run
+./scripts/deploy.sh uConsole feat/test dry-activate
+
+# Override SSH key
+SSH_KEY=/opt/data/home/.ssh/my-custom-key ./deploy.sh lazyworkhorse
+```
+
+---
+
+## Troubleshooting
+
+### "nix: command not found"
+
+- Ensure Nix is installed and PATH is set:
+  ```bash
+  export PATH="/nix/var/nix/profiles/default/bin:/root/.nix-profile/bin:$PATH"
+  ```
+- Check installation: `ls -la /nix/` should exist
+- Re-source profile: `. /root/.nix-profile/etc/profile.d/nix.sh`
+
+### "error: unable to download ... cache.nixos.org"
+
+- Check network connectivity: `ping cache.nixos.org`
+- Check DNS resolution from inside the container
+- If behind a proxy, set `http_proxy` / `https_proxy` environment variables
+
+### "sandbox: cannot run build in sandbox"
+
+- Add `sandbox = false` to nix.conf
+- Or run container with `--privileged` or `--security-opt seccomp=unconfined`
+
+### "aarch64-linux builds fail on x86_64"
+
+- QEMU binfmt not registered. Check: `ls /proc/sys/fs/binfmt_misc/`
+- Rebuild QEMU registration: `docker run --privileged --rm tonistiigi/binfmt --install all`
+- Or use `--build-host` to build on the target directly
+
+### "nixos-rebuild fails with SSH errors"
+
+- Verify SSH key exists and has correct permissions:
+  ```bash
+  ls -la /opt/data/home/.ssh/id_hermes_gitea
+  chmod 600 /opt/data/home/.ssh/id_hermes_gitea
+  ```
+- Test SSH manually: `ssh -p 2424 -i /opt/data/home/.ssh/id_hermes_gitea ai-worker@lazyworkhorse.net`
+- Check target host is reachable: `nc -zv lazyworkhorse.net 2424`
+
+### "git fetch fails from Gitea"
+
+- Verify GIT_SSH_COMMAND is set: `echo $GIT_SSH_COMMAND`
+- Test git SSH: `ssh -T git@code.lazyworkhorse.net -p 2222`
+- Check the infra repo remote: `git remote -v`
