fix: restrict docker commands for ai-worker (wrapper blacklist)

SECURITY CHANGE: Keep ai-worker in docker group but block dangerous
docker subcommands via a wrapper script.

Approach:
- docker group membership preserved (ps, start, stop, compose still work)
- Docker binary wrapped with a script that blocks dangerous subcommands
- BLOCKED: exec, cp, commit, diff, export, import, load, save, attach, push, tag
- ALLOWED: ps, images, inspect, logs, start, stop, restart, rm, rmi,
  pull, build, run, compose, system, network ls, volume ls

The wrapper is installed in both system packages and ai-worker's
personal profile to ensure it takes precedence over the real docker.
This is effective for the LLM agent threat model — the agent uses CLI
commands and blocked subcommands simply return an error.

Files modified:
- users/ai-worker.nix — restored docker group, kept sudo audit rules
- modules/nixos/security/ai-worker-restricted.nix — added docker wrapper
  script with blacklist logic and NixOS module integration
- modules/nixos/security/README-ai-worker.md — documentation update

 # AI Worker Restricted Access
 
-This module provides SSH access for the AI worker (hermes-agent) to run ollama benchmarks on the host.
+This module provides SSH access for the AI worker (hermes-agent) to run docker commands on the host with restrictions.
 
 ## Security Model
 
-The `ai-worker` user has:
+### Overview
+
+The `ai-worker` user is a member of the `docker` group, but the `docker` binary is wrapped with a script that **blocks dangerous subcommands** while allowing safe operations.
+
+### Blocked Commands
+
+These commands are intercepted by the docker wrapper and rejected:
+
+| Command | Risk | Reason |
+|---------|------|--------|
+| `docker exec` | Execute arbitrary commands inside running containers | FILE MODIFICATION |
+| `docker cp` | Copy files between containers and host | FILE ACCESS |
+| `docker commit` | Create images from running containers | DATA EXFIL |
+| `docker diff` | Inspect filesystem changes | INFO LEAK |
+| `docker export` | Export container filesystem as tar archive | DATA EXFIL |
+| `docker import` | Import a tar archive to create filesystem | FILE INJECTION |
+| `docker load` | Load images from tar archive | FILE INJECTION |
+| `docker save` | Save images to tar archive | DATA EXFIL |
+| `docker attach` | Attach to running container's stdio | INTERACTIVE ACCESS |
+| `docker push` | Push images to remote registries | DATA EXFIL |
+| `docker tag` | Tag/rename images | DATA EXFIL |
+
+Also blocked in compose context: `docker compose exec`, `docker compose cp`, etc.
+
+### Allowed Commands
+
+These commands work normally:
+
+- `docker ps` — list containers
+- `docker images` — list images
+- `docker inspect` — inspect containers/images
+- `docker logs` — view container logs
+- `docker start` — start a stopped container
+- `docker stop` — stop a running container
+- `docker restart` — restart a container
+- `docker rm` — remove a stopped container
+- `docker rmi` — remove an image
+- `docker pull` — pull an image
+- `docker build` — build an image
+- `docker run` — create and start a container
+- `docker compose` — compose orchestration (but not `compose exec`)
+- `docker system` — disk management
+- `docker network ls` — list networks
+- `docker volume ls` — list volumes
+
+### How It Works
+
+1. A wrapper script intercepts `docker` calls in the user's PATH
+2. It parses the first non-flag argument to determine the subcommand
+3. If the subcommand is in the blocklist, it prints an error and exits
+4. Otherwise, it passes through to the real Docker binary
+
+The wrapper is installed both as a system package and in ai-worker's personal profile to ensure it takes precedence over the real docker binary.
+
+### Why Not Use Docker Authorization Plugins?
+
+Docker's native authorization plugin system requires Docker-managed plugins (images) which is complex to deploy in NixOS. A CLI wrapper is simpler, maintainable, and effective for the primary threat model (an LLM agent that uses the docker CLI).
+
+Note: A determined attacker in the docker group can bypass the wrapper by calling the Docker API directly via `/var/run/docker.sock`. For the LLM agent threat model, this is a theoretical bypass — the agent uses CLI commands and `docker exec` returning an error is sufficient to stop it.
 
 ### 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

+# Expected: CONTAINER ID   IMAGE   ...
+
+# Verify docker group membership
 groups ai-worker
 # Should show: ai-worker docker
 ```
 
 ## Troubleshooting
 
-If ai-worker cannot run docker commands:
+If docker commands fail unexpectedly:
+
 ```bash
-# Check docker group membership
+# Check which docker binary is being used
-groups ai-worker
+which docker
+# If this shows /run/current-system/sw/bin/docker, the wrapper is not in PATH
 
-# Verify ollama container is running
+# Check if the wrapper is installed
-docker ps | grep ollama
+ls -la $(which docker)
 
-# Test docker access
+# Verify you're running as the right user
-sudo -u ai-worker docker exec ollama ollama list
+whoami
 ```
 
 If SSH connection fails:
+
 ```bash
 # Check SSH key is authorized
 cat /home/ai-worker/.ssh/authorized_keys
