+# DEVELOPMENT USAGE EXAMPLES
+# =============================================================================
+#
+# Quick Development Commands:
+# --------------------------
+#
+# 1. Create development infrastructure:
+#    ./core/nulib/provisioning generate infra --new mydev --template dev-basic
+#
+# 2. Validate configuration with debug output:
+#    ./core/nulib/provisioning validate config --debug
+#
+# 3. Test server creation (check mode):
+#    ./core/nulib/provisioning server create --infra mydev --check
+#
+# 4. Monitor operations with enhanced logging:
+#    ./core/nulib/provisioning show logs --follow --level debug
+#
+# 5. Interactive development shell:
+#    ./core/nulib/provisioning nu
+#
+# Development Environment Variables:
+# ---------------------------------
+# export PROVISIONING_ENV=dev
+# export PROVISIONING_DEBUG=true
+# export PROVISIONING_LOG_LEVEL=debug
+#
+# Development Testing Workflow:
+# ----------------------------
+# 1. Create test infrastructure: provisioning generate infra --new test-$(date +%s)
+# 2. Validate: provisioning validate config
+# 3. Test locally: provisioning server create --check
+# 4. Deploy to dev: provisioning server create
+# 5. Run tests: provisioning taskserv create --check
+# 6. Clean up: provisioning delete server --yes
+#
+# =============================================================================
+# DEVELOPMENT TROUBLESHOOTING
+# =============================================================================
+#
+# Common Development Issues:
+# -------------------------
+#
+# 1. SOPS Key Issues:
+#    - Check key paths in sops.key_search_paths
+#    - Verify SOPS_AGE_KEY_FILE environment variable
+#    - Test: sops -d path/to/encrypted/file
+#
+# 2. Path Configuration:
+#    - Verify paths.base points to correct directory
+#    - Check file permissions
+#    - Test: provisioning validate config
+#
+# 3. Provider Authentication:
+#    - Check cloud provider credentials
+#    - Verify API endpoints
+#    - Test: provisioning providers
+#
+# 4. Debug Output Not Showing:
+#    - Ensure debug.enabled = true
+#    - Check debug.log_level setting
+#    - Verify no_terminal = false
+#
+# 5. Performance Issues:
+#    - Reduce parallel_operations
+#    - Enable caching
+#    - Check timeout_seconds setting

+# TESTING ENVIRONMENT EXAMPLES
+# =============================================================================
+#
+# Common Testing Scenarios:
+# ------------------------
+#
+# 1. Unit Testing:
+#    export PROVISIONING_ENV=test
+#    ./core/nulib/provisioning validate config
+#    ./core/nulib/provisioning test unit
+#
+# 2. Integration Testing:
+#    export PROVISIONING_ENV=integration
+#    ./core/nulib/provisioning server create --check
+#    ./core/nulib/provisioning test integration
+#
+# 3. End-to-End Testing:
+#    ./core/nulib/provisioning test e2e --scenario basic-server
+#
+# 4. Performance Testing:
+#    ./core/nulib/provisioning test performance --load 100
+#
+# 5. Security Testing:
+#    ./core/nulib/provisioning test security --scan all
+#
+# CI/CD Pipeline Example:
+# ----------------------
+#
+# test-stage:
+#   script:
+#     - export PROVISIONING_ENV=ci
+#     - ./core/nulib/provisioning validate config --strict
+#     - ./core/nulib/provisioning test unit
+#     - ./core/nulib/provisioning test integration --check
+#     - ./core/nulib/provisioning test security
+#   artifacts:
+#     reports:
+#       junit: test-results.xml
+#     paths:
+#       - coverage/
+#       - validation-reports/
+#
+# Testing with Docker:
+# -------------------
+#
+# docker run --rm \
+#   -v $(pwd):/workspace \
+#   -e PROVISIONING_ENV=test \
+#   provisioning:test \
+#   ./core/nulib/provisioning test all
+#
+# =============================================================================
+# TESTING TROUBLESHOOTING
+# =============================================================================
+#
+# Common Testing Issues:
+# ---------------------
+#
+# 1. Test Data Isolation:
+#    - Verify paths.base points to test directory
+#    - Check test data cleanup settings
+#    - Ensure proper test fixtures
+#
+# 2. Mock Service Issues:
+#    - Verify mock services are running
+#    - Check mock service configurations
+#    - Validate mock data setup
+#
+# 3. CI/CD Integration:
+#    - Check environment variable setup
+#    - Verify artifact collection
+#    - Validate pipeline timeout settings
+#
+# 4. Performance Test Issues:
+#    - Check timeout configurations
+#    - Verify resource limits
+#    - Monitor test environment capacity
+#
+# 5. Security Test Failures:
+#    - Review security validation rules
+#    - Check compliance requirements
+#    - Verify encryption settings
+#
+# Testing Best Practices:
+# ----------------------
+#
+# 1. Test Isolation:
+#    - Use separate test directories
+#    - Clean up after each test
+#    - Avoid shared state between tests
+#
+# 2. Test Data Management:
+#    - Use fixtures for consistent data
+#    - Generate test data dynamically
+#    - Clean up test data regularly
+#
+# 3. Mock Usage:
+#    - Mock external dependencies
+#    - Use realistic mock data
+#    - Test both success and failure scenarios
+#
+# 4. CI/CD Integration:
+#    - Run tests in parallel when possible
+#    - Collect comprehensive artifacts
+#    - Set appropriate timeouts
+#
+# 5. Security Testing:
+#    - Include security scans in pipeline
+#    - Test encryption/decryption workflows
+#    - Validate access controls

+# Nushell Infrastructure Runtime Task Service
+
+> **Security-First Shell Runtime for Cloud Native Infrastructure**
+
+A secure, auditable Nushell runtime designed specifically for infrastructure servers, providing powerful scripting capabilities while maintaining strict security controls and operational safety.
+
+## 🎯 Purpose
+
+The Nushell task service provides a modern, secure shell environment for:
+- **Remote Script Execution**: Safe execution of automation scripts on infrastructure servers
+- **Observability**: Structured data collection for metrics, logs, and telemetry
+- **Infrastructure Management**: Configuration-driven server management and orchestration
+- **Security Auditing**: Complete audit trail of all shell operations and command execution
+
+## 🏗️ Architecture
+
+### Core Components
+
+```
+taskservs/nushell/
+├── default/
+│   ├── prepare                    # Environment preparation script
+│   ├── install-nushell.sh        # Nushell binary installation

+    ├── process.nu                # Log processing and analysis
+    └── telemetry.nu              # Telemetry and monitoring
+```
+
+### Security Model
+
+- **Read-Only Mode**: Default execution prevents destructive operations
+- **Command Filtering**: Allowlist/blocklist for command execution
+- **Path Restrictions**: Limited file system access to safe directories
+- **Session Timeouts**: Automatic session termination for security
+- **Audit Logging**: Complete command and operation logging
+- **Resource Limits**: CPU, memory, and network usage controls
+
+## 📋 Installation Options
+
+### 1. Standalone Installation
+
+Install Nushell as a dedicated task service:
+
+```bash
+./core/nulib/provisioning taskserv create nushell --infra <infrastructure-name>
+```
+
+### 2. Integrated with OS Base Layer
+
+Enable during OS installation for automatic deployment:
+
+```toml
+# In your infrastructure configuration
+[taskserv]
+install_nushell = true
+nushell_readonly = true
+nushell_plugins = false
+nushell_execution_mode = "restricted"
+```
+
+### 3. Conditional Installation by Server Role
+
+Configure role-based installation:
+
+```toml
+# Control nodes: Always install
+# Worker nodes: Optional based on needs
+[server.control]
+install_nushell = true
+
+[server.worker]
+install_nushell = false  # or true if needed
+```
+
+## ⚙️ Configuration
+
+### Security Settings
+
+| Setting | Default | Description |
+|---------|---------|-------------|
+| `nushell_readonly` | `true` | Enable read-only mode (blocks write operations) |
+| `nushell_execution_mode` | `"restricted"` | Execution mode: `restricted`, `normal`, `privileged` |
+| `nushell_plugins` | `false` | Enable Nushell plugins (kcl, tera, polars) |
+| `nushell_network` | `false` | Allow network operations |
+| `nushell_audit` | `true` | Enable audit logging |
+| `nushell_session_timeout` | `900` | Session timeout in seconds (15 minutes) |
+
+### Resource Limits
+
+| Setting | Default | Description |
+|---------|---------|-------------|
+| `nushell_max_memory` | `"256MB"` | Maximum memory usage |
+| `nushell_max_cpu_time` | `"30s"` | Maximum CPU time per command |
+| `nushell_remote_timeout` | `300` | Remote execution timeout (seconds) |
+
+### Command Restrictions
+
+```toml
+[taskserv]
+nushell_allowed_commands = "ls,cat,grep,ps,df,free,uptime,systemctl,kubectl"
+nushell_blocked_commands = "rm,mv,cp,chmod,chown,sudo,su"
+nushell_allowed_paths = "/tmp,/var/log,/proc,/sys"
+```
+
+## 🚀 Usage Examples
+
+### Basic System Information
+
+```nu
+# Check system health
+use /home/admin/nushell/observability/collect.nu *
+status-check
+
+# Collect system metrics
+collect-system-metrics | to json
+
+# Monitor for 5 minutes with 30s intervals
+health-monitor --duration 300 --interval 30
+```
+
+### Log Analysis
+
+```nu
+# Parse and analyze logs
+use /home/admin/nushell/observability/process.nu *
+
+# Parse system logs
+cat /var/log/syslog | lines | parse-logs --format syslog
+
+# Detect anomalies in recent logs
+collect-logs --since "1h" --level "error" | detect-anomalies --threshold 2.0
+
+# Generate comprehensive log summary
+collect-logs --since "24h" | generate-summary --include-patterns --include-anomalies
+```
+
+### Remote Execution
+
+```nu
+# Execute script with security validation
+use /home/admin/nushell/lib/remote-exec.nu *
+
+# Validate script before execution
+nu-validate-script "/tmp/monitoring-script.nu"

+health-monitoring --check-interval 60 --alert-endpoint "https://alerts.example.com/webhook"
+
+# Send custom metrics
+let custom_metrics = {app_name: "web-server", response_time: 250, status: "healthy"}
+send-telemetry $custom_metrics --format "prometheus"
+```
+
+## 🔧 Integration Patterns
+
+### SSH Remote Execution
+
+Execute Nushell scripts remotely via SSH:
+
+```bash
+# Execute health check on remote server
+ssh server-01 'nu /home/admin/nushell/observability/collect.nu -c "status-check | to json"'
+
+# Stream metrics collection
+ssh server-01 'nu -c "use /home/admin/nushell/observability/collect.nu *; health-monitor --duration 60 --interval 10"'
+```
+
+### Container Integration
+
+Use in containerized environments:
+
+```dockerfile
+# Add to your infrastructure containers
+RUN curl -L https://github.com/nushell/nushell/releases/download/0.107.1/nu-0.107.1-x86_64-unknown-linux-gnu.tar.gz | tar xz
+COPY nushell-config/ /home/app/.config/nushell/
+ENV NUSHELL_EXECUTION_MODE=restricted
+ENV NUSHELL_READONLY_MODE=true
+```
+
+### Kubernetes Jobs
+
+Deploy as Kubernetes jobs for infrastructure tasks:
+
+```yaml
+apiVersion: batch/v1
+kind: Job
+metadata:
+  name: nushell-health-check
+spec:
+  template:
+    spec:
+      containers:
+      - name: nushell
+        image: infrastructure/nushell-runtime:latest
+        command: ["nu"]
+        args: ["/scripts/health-check.nu"]
+        env:
+        - name: NUSHELL_EXECUTION_MODE
+          value: "restricted"
+        - name: NUSHELL_AUDIT_ENABLED
+          value: "true"
+```
+
+## 🛡️ Security Features
+
+### Command Validation
+
+- **Pre-execution validation**: All commands validated before execution
+- **Pattern matching**: Blocked dangerous command patterns
+- **Path validation**: File access restricted to safe directories
+- **Resource monitoring**: CPU, memory, and network usage tracked
+
+### Audit Trail
+
+Complete audit logging includes:
+- Command execution timestamps
+- User context and session information
+- Input/output data (configurable)
+- Error conditions and failures
+- Resource usage metrics
+
+### Session Management
+
+- **Automatic timeouts**: Sessions expire after inactivity
+- **Resource limits**: Memory and CPU usage constraints
+- **Network isolation**: Optional network access controls
+- **Privilege separation**: Non-privileged execution by default
+
+## 📊 Monitoring and Observability
+
+### Health Checks
+
+```nu
+# System health overview
+status-check
+
+# Detailed health monitoring
+health-monitor --interval 30 --duration 600 --output "/tmp/health-data.json"
+
+# Remote health validation
+nu-health-check
+```
+
+### Metrics Collection
+
+Automated collection of:
+- **System metrics**: CPU, memory, disk, network
+- **Process metrics**: Running processes, resource usage
+- **Container metrics**: Docker/Podman container status
+- **Kubernetes metrics**: Pod status, resource utilization
+
+### Log Processing
+
+Advanced log analysis capabilities:
+- **Multi-format parsing**: JSON, syslog, Apache, Nginx
+- **Pattern extraction**: Error patterns, IP addresses, URLs
+- **Anomaly detection**: Statistical analysis of log patterns
+- **Time-series aggregation**: Bucketed metrics over time
+
+## 🔄 Deployment Strategies
+
+### Development/Testing
+
+```toml
+[taskserv]
+install_nushell = true
+nushell_readonly = false
+nushell_plugins = true
+nushell_execution_mode = "normal"
+nushell_network = true
+```
+
+### Production
+
+```toml
+[taskserv]
+install_nushell = true
+nushell_readonly = true
+nushell_plugins = false
+nushell_execution_mode = "restricted"
+nushell_network = false
+nushell_audit = true
+nushell_session_timeout = 600
+```
+
+### High-Security Environments
+
+```toml
+[taskserv]
+install_nushell = true
+nushell_readonly = true
+nushell_plugins = false
+nushell_execution_mode = "restricted"
+nushell_network = false
+nushell_audit = true
+nushell_session_timeout = 300
+nushell_allowed_commands = "ls,cat,ps,df,free"
+nushell_blocked_commands = "rm,mv,cp,chmod,chown,sudo,su,wget,curl"
+```
+
+## 🚨 Troubleshooting
+
+### Common Issues
+
+**1. Permission Denied Errors**
+```nu
+# Check file permissions
+ls -la /home/admin/nushell/
+# Verify ownership
+ls -la ~/.config/nushell/
+```
+
+**2. Command Blocked in Read-Only Mode**
+```nu
+# Check execution mode
+echo $env.NUSHELL_EXECUTION_MODE
+# Review blocked commands
+echo $env.NUSHELL_BLOCKED_COMMANDS
+```
+
+**3. Session Timeout Issues**
+```nu
+# Check session timeout setting
+echo $env.NUSHELL_SESSION_TIMEOUT
+# Review audit log for session activity
+cat ~/nushell/audit.log | tail -20
+```
+
+**4. Plugin Loading Failures**
+```nu
+# Register plugins manually
+nu ~/nushell/scripts/register-plugins.nu
+# Check plugin availability
+plugin list
+```
+
+### Debug Mode
+
+Enable debug logging for troubleshooting:
+
+```bash
+# Set debug environment
+export NUSHELL_LOG_LEVEL=debug
+export NU_LOG_LEVEL=debug
+
+# Run with verbose output
+nu --log-level debug /path/to/script.nu
+```
+
+### Performance Issues
+
+Monitor resource usage:
+
+```nu
+# Check memory usage
+free -h
+
+# Monitor CPU usage
+top -p $(pgrep nu)
+
+# Review resource limits
+echo $env.NUSHELL_MAX_MEMORY
+echo $env.NUSHELL_MAX_CPU_TIME
+```
+
+## 📈 Performance Considerations
+
+### Resource Usage
+
+- **Memory footprint**: ~50-100MB base usage
+- **CPU overhead**: Minimal during idle, scales with workload
+- **Disk usage**: ~20MB for binary + configs
+- **Network impact**: Controlled by security settings
+
+### Optimization Tips
+
+1. **Use streaming operations** for large datasets
+2. **Enable read-only mode** for security and performance
+3. **Limit session timeouts** to prevent resource leaks
+4. **Use structured data formats** (JSON, YAML) for efficiency
+5. **Batch telemetry data** to reduce network overhead
+
+## 🔗 Integration with Other Services
+
+### KCL Configuration Language
+
+Optional integration with KCL for configuration validation:
+
+```nu
+# Install KCL plugin (if enabled)
+plugin add nu_plugin_kcl
+
+# Validate KCL configurations
+kcl run infrastructure.k | to json | from json
+```
+
+### Monitoring Systems
+
+Compatible with popular monitoring solutions:
+- **Prometheus**: Native metrics export format
+- **InfluxDB**: Line protocol support
+- **Grafana**: JSON data source integration
+- **ELK Stack**: Structured log output
+
+### CI/CD Pipelines
+
+Use in automation workflows:
+
+```yaml
+# GitHub Actions example
+- name: Infrastructure Health Check
+  run: |
+    ssh ${{ secrets.SERVER_HOST }} 'nu -c "
+      use /home/admin/nushell/observability/collect.nu *;
+      status-check | to json
+    "'
+```
+
