 ## Build & Deployment
 
 - **Build/Deploy:** Use `nixos-rebuild switch --flake .#<hostname>` to build and deploy the configuration for a specific host.
-- **CRITICAL — Validate before pushing:** Always `nix build --no-link '.#nixosConfigurations.<hostname>.config.system.build.toplevel'` (or `nh os build`) and confirm it succeeds before pushing any changes. Never push untested NixOS configs.
 - **Development Shell:** Activate the development environment with `nix develop`.

-This module provides SSH access for the AI worker (hermes-agent) to run ollama benchmarks on the host.

-## Security Model
-
-The `ai-worker` user has:
-
-### 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
-```
-
-## SSH Access
-
-Connect as:
-```bash
-ssh ai-worker@lazyworkhorse
-```
-
-The working directory will be `/home/ai-worker`. No infra repo access.
-
-## Verification
-
-Check ai-worker permissions:
-```bash
-# On the host, as root or gortium:
-sudo -u ai-worker sudo -l
-# Should show: no sudo access
-
-# Check docker group membership
-groups ai-worker
-# Should show: ai-worker docker
-```
-
-## Troubleshooting
-
-If ai-worker cannot run docker commands:
-```bash
-# Check docker group membership
-groups ai-worker
-
-# Verify ollama container is running
-docker ps | grep ollama
-
-# Test docker access
-sudo -u ai-worker docker exec ollama ollama list
-```
-
-If SSH connection fails:
-```bash
-# Check SSH key is authorized
-cat /home/ai-worker/.ssh/authorized_keys
-
-# Check SSH service
-systemctl status sshd
-```

-# run-integration.sh — Staging VM Integration Test Suite
-#
-# Verifies Docker daemon, compose stack, and service endpoint health.
-# Designed to run inside the staging VM as part of CI/CD pipeline.
-#
-# Usage:
-#   ./tests/run-integration.sh                  # all defaults
-#   ./tests/run-integration.sh --verbose         # detailed output
-#   ./tests/run-integration.sh --list-services   # print detected services and exit
-#
-# Environment variables (all optional):
-#   COMPOSE_DIR       Path to compose service directories  (default: /opt/infra/compose)
-#   COMPOSE_PROJECT   Docker Compose project name          (default: staging)
-#   STAGING_DOMAIN    Base domain for health checks        (default: staging.lazyworkhorse.net)
-#   SERVICE_LIST      Space-separated service dirs to check (default: auto-detect)
-#   HEALTH_URLS       Space-separated URLs for health checks (default: auto-detect from SERVICE_LIST)
-#   HEALTH_TIMEOUT    Curl timeout per check (seconds)      (default: 5)
-#   HEALTH_RETRIES    Number of retries per endpoint         (default: 1)
-#   HEALTH_INTERVAL   Seconds between retries                (default: 2)
