feat: add Hyperspace Pods NixOS module
Create modules/nixos/services/hyperspace.nix for the Hyperspace Pods
P2P AI cluster agent. Registered in flake.nix under lazyworkhorse.
- Fetches CLI binary v5.45.30 via fetchurl with SRI hash verification
- Systemd system service: auto profile, configurable api port 8080,
ai-worker user, GPU device access (kfd+dri), SupplementaryGroups
for video+render groups, service hardening
- Firewall: TCP 4001 libp2p, 30301 chain, 8080 API; UDP 4001 libp2p
- AMD MI50 ROCm via HSA_OVERRIDE_GFX_VERSION=9.0.6
- Adds video+render groups to ai-worker for persistent GPU access

# AI Worker Restricted Access # AI Worker Restricted Access
This module provides SSH access for the AI worker (hermes-agent) to run docker commands on the host. This module provides SSH access for the AI worker (hermes-agent) to run ollama benchmarks on the host.
## Security Model ## Security Model
### Overview The `ai-worker` user has:
The `ai-worker` user has **no direct docker group access**. All docker commands must go through `sudo`, and only specific subcommands are whitelisted:
- **Container lifecycle**: `docker ps`, `docker inspect`, `docker logs`, `docker images`, `docker info`, `docker version`, `docker stats`
- **Control**: `docker start`, `docker stop`, `docker restart`, `docker rm`, `docker rmi`, `docker wait`
- **Image management**: `docker pull`, `docker build`, `docker run`, `docker compose`
- **Disk cleanup**: `docker system`
- **Network/Volume**: `docker network ls`, `docker volume ls` (read-only)
### EXPLICITLY BLOCKED (not in sudo whitelist)
| Command | Risk | Result |
|---------|------|--------|
| `docker exec` | Execute arbitrary commands inside containers (FILE MODIFICATION) | Blocked by sudo |
| `docker cp` | Copy files between containers and host | Blocked by sudo |
| `docker commit` | Create images from running containers (data exfil) | Blocked by sudo |
| `docker diff` | Inspect filesystem changes | Blocked by sudo |
| `docker export` | Export container filesystem | Blocked by sudo |
| `docker import` | Import filesystem archives | Blocked by sudo |
| `docker load` | Load docker images | Blocked by sudo |
| `docker save` | Save docker images to tar | Blocked by sudo |
| `docker attach` | Interactive access to containers | Blocked by sudo |
| `docker push` | Push images to registries | Blocked by sudo |
| `docker tag` | Rename images | Blocked by sudo |
### Why This Approach?
Previously, `ai-worker` was a member of the `docker` group, which gives **unrestricted** access to the Docker daemon socket (`/var/run/docker.sock`). Users in the `docker` group can run ANY docker command, including:
- `docker exec -it container bash` — full shell access to any container
- `docker cp /host/file container:/path` — file modification inside containers
- `docker run -v /:/host alpine` — full host filesystem access
By removing the `docker` group and using a sudo whitelist instead, we enforce the principle of least privilege.
### Filesystem Access ### Filesystem Access
- **Home directory**: `/home/ai-worker` (standard user home) - **Home directory**: `/home/ai-worker` (standard user home)

- **Cannot access**: Any files outside standard system paths - **Cannot access**: Any files outside standard system paths
### Sudo Access ### Sudo Access
- **Restricted**: ai-worker has `NOPASSWD` access only to whitelisted commands - **NONE**: ai-worker has no sudo privileges
- Cannot run `nh`, `nixos-rebuild`, `nixpkgs-fmt`, or `nix` with elevated permissions - Cannot run `nh`, `nixos-rebuild`, `nixpkgs-fmt`, or `nix` with elevated permissions
## Workflow: SSH + Restricted Docker ### 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
All docker commands must be prefixed with `sudo`: ## 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 ```bash
# From Hermes container, SSH to host # From Hermes container, SSH to host
ssh -i /path/to/ssh/key ai-worker@host.docker.internal ssh -i /path/to/ssh/key ai-worker@host.docker.internal
# Check container status (works) # On host, run ollama benchmarks via docker
sudo docker ps docker exec ollama ollama pull devstral-small-2:24b
# Restart a container (works) # Create test modelfile
sudo docker restart ollama 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'
# Run benchmark (works - docker run is allowed) # Create and test model
sudo docker run --rm alpine echo "test" docker exec ollama ollama create test-model -f /root/.ollama/test.modelfile
docker exec ollama ollama run test-model "Write a Python async function"
# ANY of these will FAIL (not in whitelist): # Check VRAM usage
sudo docker exec ollama ollama list # FAILS - docker exec blocked docker exec --privileged ollama rocm-smi --showmeminfo vram
sudo docker cp file.txt container:/path/ # FAILS - docker cp blocked
sudo docker commit container new-image # FAILS - docker commit blocked
# For ollama operations, use the HTTP API instead of docker exec: # Cleanup
curl http://ollama:11434/api/tags docker exec ollama ollama rm test-model
# Exit SSH, return to Hermes container
exit
# Save results in Hermes container
