 # AI Worker Restricted Access
 
-This module provides SSH access for the AI worker (hermes-agent) to run docker commands on the host with restrictions.
+This module provides SSH access for the AI worker (hermes-agent) to run ollama benchmarks on the host.
 
 ## Security Model
 
-### Overview
+The `ai-worker` user has:
-
-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
+```

 ## Verification
 
+Check ai-worker permissions:
 ```bash
-# Verify wrapper is in PATH
+# On the host, as root or gortium:
-sudo -u ai-worker which docker
+sudo -u ai-worker sudo -l
-# Should show: /home/ai-worker/.nix-profile/bin/docker (wrapped version)

 ## Troubleshooting

-
 ```bash
-# Check which docker binary is being used
+# Check docker group membership
-which docker
