fix: restrict docker commands for ai-worker user

Remove ai-worker from docker group and enforce sudo whitelist. SECURITY: Being in the docker group gives unrestricted access to the Docker daemon socket (/var/run/docker.sock), allowing any docker command: docker exec, docker cp, docker run -v /:/host, docker commit, etc. Changes: - Remove extraGroups = ["docker"] from ai-worker user definition - Add comprehensive sudo NOPASSWD whitelist for safe docker subcommands ALLOWED: ps, inspect, logs, images, info, version, stats, start, stop, restart, rm, rmi, wait, pull, build, run, compose, system, network ls, volume ls BLOCKED (implicitly): exec, cp, commit, diff, export, import, load, save, attach, push, tag, create, plugin, network create, volume create - Update ai-worker-restricted.nix module to reflect new approach - Update README-ai-worker.md with new security model and examples All docker commands must now be prefixed with sudo. The Hermes agent's host_run tool needs to be updated to prepend sudo.

-      # CROSS-COMPILE WORKAROUNDS — packages that fail aarch64 cross-compile
-      #
-      # These packages need NATIVE COMPILATION on the uConsole itself (aarch64).
-      # They cannot cross-compile from x86_64 for various reasons listed below.
-      # We work around them in the overlay until we set up distributed builds
-      # with the uConsole as a native aarch64 builder.
-      #
-      # ==== Cross-compile failures ====
-      #
-      # libcamera / libcamera-rpi / libpisp:
-      #   meta.platforms excludes aarch64. pipewire hard-depends on them in nixos-25.11.
-      #   Fix: empty meta.platforms + strip from pipewire buildInputs.
-      #
-      # gjs:
-      #   Need native display (GTK3/4 tests) for cross-compile configure.
-      #   Fix: meson -Dskip_gtk_tests=true.
-      #
-      # hyprland:
-      #   Qt6Quick missing from aarch64 qtdeclarative, breaks hyprland-qt-support.
-      #   Fix: wrapRuntimeDeps=false (Qt UI components disabled, WM still works).
-      #
-      # boost.mpi:
-      #   Boost.Build has no b2 architecture alternatives for ARM.
-      #   Fix: useMpi=false.
-      #
-      # perl-ldap (perlPackages.perlldap):
-      #   Module::Install requires Perl dynamic loading (Fcntl) which is
-      #   unavailable in cross-compiled Perl.
-      #   Fix: stripped from john.s propagatedBuildInputs.
-      #
-      # john (John the Ripper):
-      #   Indirectly affected — depends on perl-ldap for perl utility scripts.
-      #   Fix: perl-ldap stripped from propagatedBuildInputs (john still works,
-      #   just loses sha-dump.pl etc. LDAP support).
-      #
-      # gss (GNU Generic Security Service):
-      #   autogen.sh fails cross-compile. Pulled by mailutils → emacs-pgtk.
-      #   Fix: emacs withMailutils=false.
-      #
-      # emacs-pgtk:
-      #   Indirectly affected — depends on mailutils which depends on gss.
-      #   Fix: withMailutils=false (no mail/IMAP within emacs).
-      #
-      # qtquick3d (Qt6):
-      #   Qt::Quick not available in aarch64 cross-compile qtdeclarative.
-      #   cmake skips build, ninja has no install target.
-      #   Fix: removed js8call, switched wireshark → wireshark-cli.
-      #
-      # js8call:
-      #   REMOVED from system packages. Depends on Qt6 multimedia → qtquick3d.
-      #
-      # wireshark-qt:
-      #   SWITCHED to wireshark-cli. Same Qt6 multimedia → qtquick3d chain.
-      #
-# neovim:
-#   `libnlua0.so` built for aarch64, luajit (x86_64) tries to load it
-#   during codegen (preload_nlua.lua). No clean override option.
-#   Fix: remove from system packages + install via native build
-#   once uConsole is set up as remote builder.
-#
-# clamav:
-#   cmake try_run() + Rust proc-macro can't find native linker in
-#   cross-compile (cc crate uses cross CC, no cc in PATH for build
-#   scripts). Chain: clamav → system-path → etc → dbus → polkit.
-#   Fix: remove from system packages; clamscan available from server.
-
-#
-# ==== Remote builder setup (bidirectional) — TODO ====
-# To eliminate cross-compile exceptions, set up distributed builds:
-# 1. Create a dedicated `builder` user on both hosts (no shell, home=/var/empty)
-# 2. Add the same SSH key to both hosts (symmetric)
-# 3. On lazyworkhorse — `nix.buildMachines` pointing to uConsole for aarch64-linux
-# 4. On uConsole — `nix.buildMachines` pointing to lazyworkhorse for x86_64-linux
-# 5. Remove the uconsoleCrossOverlay workarounds above
-# 6. Nix auto-dispatches derivations by `system` — no per-package exceptions needed
-# Example buildMachines config:
-# Server dispatches aarch64 builds to uConsole (4 cores, less power):
-#   nix.buildMachines = [{
-#     hostName = "uConsole.local";
-#     systems = ["aarch64-linux"];
-#     maxJobs = 4;
-#     sshUser = "builder";
-#     sshKey = "/etc/ssh/builder_key";
-#   }];
-# uConsole dispatches x86_64 builds to server (36 cores, 256GB RAM):
-#   nix.buildMachines = [{
-#     hostName = "lazyworkhorse.net";
-#     port = 2424;
-#     systems = ["x86_64-linux"];
-#     maxJobs = 36;
-#     sshUser = "builder";
-#     sshKey = "/etc/ssh/builder_key";
-#   }];
-
-      # ==== How to build natively on uConsole ====
-      # To native-compile these on the uConsole:
-      # 1. Add uConsole as a remote builder (nix.buildMachines)
-      # 2. Set nix.extra-platforms = [ "aarch64-linux" ] on server
-      # 3. Remove the overlay workarounds below
-      # 4. Packages will auto-dispatch to uConsole for native builds

 # 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.

 ## Security Model

-The `ai-worker` user has:
+### Overview
+
+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
 - **Home directory**: `/home/ai-worker` (standard user home)
@@ -12,51 +46,33 @@ The `ai-worker` user has:
 - **Cannot access**: Any files outside standard system paths

 ### Sudo Access
- **NONE**: ai-worker has no sudo privileges
+- **Restricted**: ai-worker has `NOPASSWD` access only to whitelisted commands
 - 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 + Restricted Docker

-## 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
+All docker commands must be prefixed with `sudo`:

 ```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
+# Check container status (works)
+sudo docker ps

-# 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'
+# Restart a container (works)
+sudo docker restart ollama

-# 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"
+# Run benchmark (works - docker run is allowed)
+sudo docker run --rm alpine echo "test"

-# Check VRAM usage
-docker exec --privileged ollama rocm-smi --showmeminfo vram
+# ANY of these will FAIL (not in whitelist):
+sudo docker exec ollama ollama list          # FAILS - docker exec blocked
+sudo docker cp file.txt container:/path/     # FAILS - docker cp blocked
+sudo docker commit container new-image       # FAILS - docker commit blocked

-# 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
+# For ollama operations, use the HTTP API instead of docker exec:
+curl http://ollama:11434/api/tags
 ```

 ```bash
 # On the host, as root or gortium:

-# Check docker group membership
