Refactor emacs configuration and clean up lab-tool project

- Reorganized emacs configuration with profiles in modules/development/emacs.nix
- Updated machine configurations to use new emacs module structure
- Cleaned up lab-tool project by removing archive, research, testing, and utils directories
- Streamlined lab-tool to focus on core deployment functionality with deploy-rs
- Added DEVELOPMENT.md documentation for lab-tool

+# Lab Tool Development Guide
+
+## Build Commands
+
+### Build the Lab Tool Package
+```bash
+# Build the lab tool from project root
+nix build .#packages.x86_64-linux.lab
+
+# The binary will be available at ./result/bin/lab
+```
+
+### Quick Development Build
+```bash
+# From the lab-tool directory
+cd packages/lab-tool
+nix build .#lab-tool  # if available, otherwise use full path above
+```
+
+## Testing Commands
+
+### Test Lab Tool Functionality
+```bash
+# Test help command
+./result/bin/lab help
+
+# Test machine listing
+./result/bin/lab machines
+
+# Test status check
+./result/bin/lab status
+
+# Test dry-run deployment
+./result/bin/lab deploy little-rascal --dry-run
+
+# Test actual deployment
+./result/bin/lab deploy little-rascal
+```
+
+### Test System Integration
+```bash
+# Deploy configuration using nixos-rebuild (requires sudo access)
+sudo nixos-rebuild switch --flake .#little-rascal --show-trace
+
+# Or using lab tool (recommended)
+lab deploy little-rascal
+```
+
+## Development Workflow
+
+### 1. Make Changes
+Edit source files in:
+- `main.scm` - CLI interface
+- `lab/deployment.scm` - Deployment logic
+- `lab/machines.scm` - Machine management
+- `utils/*.scm` - Utility functions
+
+### 2. Build and Test
+```bash
+# Rebuild after changes
+nix build .#packages.x86_64-linux.lab
+
+# Test basic functionality
+./result/bin/lab help
+./result/bin/lab machines
+
+# Test deployment (dry-run first)
+./result/bin/lab deploy little-rascal --dry-run
+```
+
+### 3. Debug Issues
+```bash
+# Enable Guile debugging
+export GUILE_AUTO_COMPILE=0
+
+# Run with verbose output
+./result/bin/lab deploy little-rascal --dry-run
+
+# Check deploy-rs command directly
+deploy --help
+```
+
+## Common Development Tasks
+
+### Update Deploy-rs Command Format
+Edit `lab/deployment.scm` in the `build-deploy-command` function:
+```scheme
+;; Example: Add new flags
+(when new-option
+  (set! flags (cons "--new-flag=value" flags)))
+```
+
+### Add New Machine
+Add to the machine list in `lab/machines.scm` or config files.
+
+### Debug Deployment Issues
+1. Check the generated command with dry-run
+2. Test deploy-rs directly: `deploy '.#little-rascal' --dry-activate`
+3. Check flake structure: `nix flake show`
+
+### Module Structure
+- `main.scm` - Entry point and CLI parsing
+- `lab/core.scm` - Core lab functionality
+- `lab/deployment.scm` - Deploy-rs integration
+- `lab/machines.scm` - Machine management
+- `lab/monitoring.scm` - Health checks and monitoring
+- `lab/auto-update.scm` - Automatic update system
+- `utils/logging.scm` - Logging system with colors
+- `utils/config.scm` - Configuration management
+- `utils/ssh.scm` - SSH utilities
+- `utils/json.scm` - JSON handling
+
+## Troubleshooting
+
+### Build Failures
+```bash
+# Check flake structure
+nix flake show
+
+# Verify Guile syntax
+guile --no-auto-compile -c "(load \"main.scm\")"
+```
+
+### Runtime Errors
+```bash
+# Check module exports
+guile -c "(use-modules (lab deployment)) (display 'loaded)"
+
+# Test individual functions
+guile -c "(use-modules (lab deployment)) (deploy-machine \"little-rascal\" \"default\" '((dry-run . #t)))"
+```
+
+### Deploy-rs Issues
+```bash
+# Test deploy-rs directly
+deploy '.#little-rascal' --dry-activate
+
+# Check machine connectivity
+ssh sma@little-rascal 'echo "connected"'
+```
+
+## Best Practices
+
+1. **Always test with dry-run first**
+2. **Use the lab tool instead of direct nixos-rebuild when possible**
+3. **Check flake status before deployment** (`nix flake check`)
+4. **Keep commits atomic** - one feature/fix per commit
+5. **Update this file when adding new commands or workflows**

-## ✅ TDD Success Summary
-
-### Fixed Issues
-1. **Syntax errors in deployment.scm** - Missing parentheses and corrupted module definition
-2. **Missing exports in utils/logging.scm** - Added `get-color` function to exports
-3. **Error handling in main.scm** - Proper exit codes for invalid commands
-4. **Module loading** - All modules now load without compilation issues
-
-### Verified Working Features
-- ✅ **CLI Interface**: help, status, machines, deploy, health, test-modules
-- ✅ **Real Deployment**: Successfully deploys to actual NixOS machines
-- ✅ **Infrastructure Monitoring**: Checks machine status across the lab
-- ✅ **Error Handling**: Proper error messages and exit codes
-- ✅ **Modular Architecture**: K.I.S.S principles applied throughout
-
-### Test Organization
-- All test files moved to `testing/` directory
-- Clear test categories and documentation
-- TDD approach validated all functionality
-
-## 🚀 Ready for Production
-
-The lab tool is now fully functional for core home lab operations:
-- Deploy NixOS configurations to any machine
-- Monitor infrastructure status
-- Manage machine health checks
-- Clean, modular codebase following K.I.S.S principles
-
-## 📋 Next Steps
-
-Priority items from TODO.md:

-# K.I.S.S Refactoring Summary
-
-## Applied Principles
-
-### 1. Modularization (Keep It Simple, Keep It Small)
-
-- **Before**: Large monolithic modules (138+ lines)
-- **After**: Small focused modules (each under 50 lines)
-- **Example**: SSH module split into 5 specialized modules
-
-### 2. Single Responsibility Principle (UNIX Philosophy: Do One Thing Well)
-
-- **connection-test.scm**: Only SSH connectivity testing
-- **remote-command.scm**: Only remote command execution  
-- **file-copy.scm**: Only file transfer operations
-- **retry.scm**: Only retry logic
-- **context.scm**: Only connection context management
-
-### 3. Functional Programming Patterns
-
-- **Pure Functions First**: All core logic implemented as pure functions
-- **Immutable Data**: Configuration and data structures remain immutable
-- **Separation of Concerns**: Pure functions separated from side effects
-
-### 4. Function-Level Modularity
-
-Each module exports both:
-
-- **Pure functions**: For testing, composition, and functional programming
-- **Impure wrappers**: For convenience and logging
-
-## Module Structure
-
-```

-
-## Benefits Achieved
-
-### 1. Testability
-
-- Pure functions can be tested in isolation
-- No side effects to mock or manage
-- Clear input/output contracts
-
-### 2. Composability  
-
-- Small functions can be easily combined
-- Pure functions enable functional composition
-- Reusable building blocks
-
-### 3. Maintainability
-
-- Single responsibility makes modules easy to understand
-- Changes are localized to specific modules
-- Clear separation between pure and impure code
-
-### 4. Code Reuse
-
-- Pure functions can be reused across different contexts
-- Both pure and impure versions available
-- Facade modules provide convenient interfaces
-
-## Usage Examples
-
-### Pure Function Composition
-
-```scheme
-;; Test connection and get config in one go
-(let ((ssh-config (get-ssh-config-pure config "machine-name")))
-  (if (test-ssh-connection-pure ssh-config)
-      (run-remote-command-pure ssh-config "uptime" '())
-      #f))
-```
-
-### Convenient Impure Wrappers
-
-```scheme
-;; Same operation with logging and error handling
-(with-ssh-connection "machine-name"
-  (lambda () (run-remote-command "machine-name" "uptime")))
-```
-
-### Functional Pipeline
-
-```scheme
-;; Pure validation pipeline
-(let* ((config (load-config-from-file "config.json"))
-       (valid? (validate-json-schema config machine-schema))
-       (machines (if valid? (get-all-machines-pure config) '())))
-  machines)
-```
-
-This refactoring transforms the codebase from monolithic modules into a collection of small, focused, composable functions that follow functional programming principles while maintaining practical usability.

-# Guile Scheme Coding Instructions for Home Lab Tool
-
-## Functional Programming Principles
-
-**Core Philosophy**: Functional programming is about actions, data, and computation - compose small, pure functions to build complex behaviors.
-
-### 1. Pure Functions First
-- Functions should be deterministic and side-effect free when possible
-- Separate pure computation from I/O operations
-- Use immutable data structures as default
-
-```scheme
-;; Good: Pure function
-(define (calculate-deployment-hash config)
-  (sha256 (scm->json-string config)))
-
-;; Better: Separate pure logic from I/O
-(define (deployment-ready? machine-config current-state)
-  (and (eq? (assoc-ref machine-config 'status) 'configured)
-       (eq? (assoc-ref current-state 'connectivity) 'online)))
-
-;; I/O operations separate
-(define (check-machine-deployment machine)
-  (let ((config (load-machine-config machine))
-        (state (probe-machine-state machine)))
-    (deployment-ready? config state)))
-```
-
-### 2. Data-Driven Design
-- Represent configurations and state as data structures
-- Use association lists (alists) and vectors for structured data
-- Leverage Guile's homoiconicity (code as data)
-
-```scheme
-;; Machine configuration as data
-(define machine-specs
-  `((grey-area 
-     (services (ollama jellyfin forgejo))
-     (deployment-method deploy-rs)
-     (backup-schedule weekly))
-    (sleeper-service
-     (services (nfs zfs monitoring))
-     (deployment-method hybrid-update)
-     (backup-schedule daily))))
-
-;; Operations on data
-(define (get-machine-services machine)
-  (assoc-ref (assoc-ref machine-specs machine) 'services))
-
-(define (machines-with-service service)
-  (filter (lambda (machine-spec)
-            (member service (get-machine-services (car machine-spec))))
-          machine-specs))
-```
-
-## Guile-Specific Idioms
-
-### 3. Module Organization
-- Use meaningful module hierarchies
-- Export only necessary public interfaces
-- Group related functionality together
-
-```scheme
-;; File: modules/lab/machines.scm
-(define-module (lab machines)
-  #:use-module (srfi srfi-1)    ; List processing
-  #:use-module (srfi srfi-26)   ; Cut/cute
-  #:use-module (ice-9 match)    ; Pattern matching
-  #:use-module (ssh session)
-  #:export (machine-status
-            deploy-machine
-            list-machines
-            machine-services))
-
-;; File: modules/lab/deployment.scm
-(define-module (lab deployment)
-  #:use-module (lab machines)
-  #:use-module (json)
-  #:export (deploy-rs
-            hybrid-update
-            rollback-deployment))
-```
-
-### 4. Error Handling the Scheme Way
-- Use exceptions for exceptional conditions
-- Return #f or special values for expected failures
-- Provide meaningful error context
-
-```scheme
-;; Use exceptions for programming errors
-(define (deploy-machine machine method)
-  (unless (member machine (list-machines))
-    (throw 'invalid-machine "Unknown machine" machine))
-  (unless (member method '(deploy-rs hybrid-update legacy))
-    (throw 'invalid-method "Unknown deployment method" method))
-  ;; ... deployment logic)
-
-;; Return #f for expected failures
-(define (machine-reachable? machine)
-  (catch #t
-    (lambda ()
-      (ssh-connect machine)
-      #t)
-    (lambda (key . args)
-      #f)))
-
-;; Provide context with failure info
-(define (deployment-result success? machine method details)
-  `((success . ,success?)
-    (machine . ,machine)
-    (method . ,method)
-    (timestamp . ,(current-time))
-    (details . ,details)))
-```
-
-### 5. Higher-Order Functions and Composition
-- Use map, filter, fold for list processing
-- Compose functions to build complex operations
-- Leverage SRFI-1 for advanced list operations
-
-```scheme
-(use-modules (srfi srfi-1))
-
-;; Functional composition
-(define (healthy-machines machines)
-  (filter machine-reachable?
-          (filter (lambda (m) (not (maintenance-mode? m)))
-                  machines)))
-
-;; Map operations across machines
-(define (update-all-machines)
-  (map (lambda (machine)
-         (cons machine (update-machine machine)))
-       (healthy-machines (list-machines))))
-
-;; Fold for aggregation
-(define (deployment-summary results)
-  (fold (lambda (result acc)
-          (if (assoc-ref result 'success)
-              (cons 'successful (1+ (assoc-ref acc 'successful)))
-              (cons 'failed (1+ (assoc-ref acc 'failed)))))
-        '((successful . 0) (failed . 0))
-        results))
-```
-
-### 6. Pattern Matching for Control Flow
-- Use `match` for destructuring and dispatch
-- Pattern match on data structures
-- Cleaner than nested if/cond statements
-
-```scheme
-(use-modules (ice-9 match))
-
-(define (handle-deployment-event event)
-  (match event
-    (('start machine method)
-     (log-info "Starting deployment of ~a using ~a" machine method))
-    
-    (('progress machine percent)
-     (update-progress-bar machine percent))
-    
-    (('success machine result)
-     (log-success "Deployment completed: ~a" machine)
-     (notify-success machine result))
-    
-    (('error machine error-msg)
-     (log-error "Deployment failed: ~a - ~a" machine error-msg)
-     (initiate-rollback machine))
-    
-    (_ (log-warning "Unknown event: ~a" event))))
-
-;; Pattern matching for configuration parsing
-(define (parse-machine-config config-sexp)
-  (match config-sexp
-    (('machine name ('services services ...) ('options options ...))
-     `((name . ,name)
-       (services . ,services)
-       (options . ,(alist->hash-table options))))
-    
-    (_ (throw 'invalid-config "Malformed machine config" config-sexp))))
-```
-
-### 7. REPL-Driven Development
-- Design for interactive development
-- Provide introspection functions
-- Make state queryable and modifiable
-
-```scheme
-;; REPL helpers for development
-(define (debug-machine-state machine)
-  "Display comprehensive machine state for debugging"
-  (format #t "Machine: ~a~%" machine)
-  (format #t "Status: ~a~%" (machine-status machine))
-  (format #t "Services: ~a~%" (machine-services machine))
-  (format #t "Last deployment: ~a~%" (last-deployment machine))
-  (format #t "Reachable: ~a~%" (machine-reachable? machine)))
-
-;; Interactive deployment with confirmation
-(define (interactive-deploy machine)
-  (let ((current-config (get-machine-config machine)))
-    (display-config current-config)
-    (when (yes-or-no? "Proceed with deployment?")
-      (deploy-machine machine 'deploy-rs))))
-
-;; State introspection
-(define (lab-status)
-  `((total-machines . ,(length (list-machines)))
-    (reachable . ,(length (filter machine-reachable? (list-machines))))
-    (services-running . ,(total-running-services))
-    (pending-deployments . ,(length (pending-deployments)))))
-```
-
-### 8. Concurrency with Fibers
-- Use fibers for concurrent operations
-- Non-blocking I/O for better performance
-- Coordinate parallel deployments safely
-
-```scheme
-(use-modules (fibers) (fibers channels))
-
-;; Concurrent machine checking
-(define (check-all-machines-concurrent machines)
-  (run-fibers
-    (lambda ()
-      (let ((results-channel (make-channel)))
-        ;; Spawn fiber for each machine
-        (for-each (lambda (machine)
-                    (spawn-fiber
-                      (lambda ()
-                        (let ((status (check-machine-status machine)))
-                          (put-message results-channel 
-                                     (cons machine status))))))
-                  machines)
-        
-        ;; Collect results
-        (let loop ((remaining (length machines))
-                   (results '()))
-          (if (zero? remaining)
-              results
-              (loop (1- remaining)
-                    (cons (get-message results-channel) results))))))))
-
-;; Parallel deployment with coordination
-(define (deploy-machines-parallel machines)
-  (run-fibers
-    (lambda ()
-      (let ((deployment-channel (make-channel))
-            (coordinator (spawn-fiber (deployment-coordinator deployment-channel))))
-        (par-map (lambda (machine)
-                   (deploy-with-coordination machine deployment-channel))
-                 machines)))))
-```
-
-### 9. MCP Server Implementation Patterns
-- Structured message handling
-- Capability-based tool organization
-- Resource management with caching
-
-```scheme
-;; MCP message dispatch
-(define (handle-mcp-request request)
-  (match (json-ref request "method")
-    ("tools/list" 
-     (mcp-tools-list))
-    
-    ("tools/call"
-     (let ((tool (json-ref request "params" "name"))
-           (args (json-ref request "params" "arguments")))
-       (call-lab-tool tool args)))
-    
-    ("resources/list"
-     (mcp-resources-list))
-    
-    ("resources/read"
-     (let ((uri (json-ref request "params" "uri")))
-       (read-lab-resource uri)))
-    
-    (method
-     (mcp-error -32601 "Method not found" method))))
-
-;; Tool capability definition
-(define lab-tools
-  `((deploy-machine
-     (description . "Deploy configuration to a specific machine")
-     (inputSchema . ,(json-schema
-                      `((type . "object")
-                        (properties . ((machine (type . "string"))
-                                     (method (type . "string") 
-                                            (enum . ("deploy-rs" "hybrid-update")))))
-                        (required . ("machine")))))
-     (handler . ,deploy-machine-tool))
-    
-    (check-status
-     (description . "Check machine status and connectivity")
-     (inputSchema . ,(json-schema
-                      `((type . "object")
-                        (properties . ((machines (type . "array")
-                                                (items (type . "string"))))))))
-     (handler . ,check-status-tool))))
-```
-
-### 10. Configuration and Environment
-- Use parameters for configuration
-- Environment-aware defaults
-- Validate configuration on startup
-
-```scheme
-;; Configuration parameters
-(define lab-config-dir 
-  (make-parameter (or (getenv "LAB_CONFIG_DIR") 
-                      "/etc/lab-tool")))
-
-(define deployment-timeout
-  (make-parameter (string->number (or (getenv "DEPLOYMENT_TIMEOUT") "300"))))
-
-(define ssh-key-path
-  (make-parameter (or (getenv "LAB_SSH_KEY")
-                      (string-append (getenv "HOME") "/.ssh/lab_key"))))
-
-;; Configuration validation
-(define (validate-lab-config)
-  (unless (file-exists? (lab-config-dir))
-    (throw 'config-error "Lab config directory not found" (lab-config-dir)))
-  
-  (unless (file-exists? (ssh-key-path))
-    (throw 'config-error "SSH key not found" (ssh-key-path)))
-  
-  (unless (> (deployment-timeout) 0)
-    (throw 'config-error "Invalid deployment timeout" (deployment-timeout))))
-
-;; Initialize with validation
-(define (init-lab-tool)
-  (validate-lab-config)
-  (load-machine-configurations)
-  (initialize-ssh-agent)
-  (setup-logging))
-```
-
-## Code Style Guidelines
-
-### 11. Naming Conventions
-- Use kebab-case for variables and functions
-- Predicates end with `?`
-- Mutating procedures end with `!`
-- Constants in ALL-CAPS with hyphens
-
-```scheme
-;; Good naming
-(define DEFAULT-SSH-PORT 22)
-(define machine-deployment-status ...)
-(define (machine-reachable? machine) ...)
-(define (update-machine-config! machine config) ...)
-
-;; Avoid
-(define defaultSSHPort 22)           ; camelCase
-(define machine_status ...)          ; snake_case
-(define (is-machine-reachable ...) ; unnecessary 'is-'
-```
-
-### 12. Documentation and Comments
-- Document module purposes and exports
-- Use docstrings for complex functions
-- Comment the "why", not the "what"
-
-```scheme
-(define (deploy-machine machine method)
-  "Deploy configuration to MACHINE using METHOD.
-   
-   Returns a deployment result alist with success status, timing,
-   and any error messages. May throw exceptions for invalid inputs."
-  
-  ;; Validate inputs early to fail fast
-  (validate-machine machine)
-  (validate-deployment-method method)
-  
-  ;; Use atomic operations to prevent partial deployments
-  (call-with-deployment-lock machine
-    (lambda ()
-      (let ((start-time (current-time)))
-        ;; ... deployment logic
-        ))))
-```
-
-### 13. Testing Approach
-- Write tests for pure functions first
-- Mock I/O operations
-- Use SRFI-64 testing framework
-
-```scheme
-(use-modules (srfi srfi-64))
-
-(test-begin "machine-configuration")
-
-(test-equal "machine services extraction"
-  '(ollama jellyfin forgejo)
-  (get-machine-services 'grey-area))
-
-(test-assert "deployment readiness check"
-  (deployment-ready? 
-    '((status . configured) (health . good))
-    '((connectivity . online) (load . normal))))
-
-(test-error "invalid machine throws exception"
-  'invalid-machine
-  (deploy-machine 'non-existent-machine 'deploy-rs))
-
-(test-end "machine-configuration")
-```
-

-- Use `deploy-rs` for production deployments
-- Test with `hybrid-update` in development
-- Always backup before major changes

-# Replacing Bash with Guile Scheme for Home Lab Tools
-
-This document outlines a proposal to migrate the `home-lab-tools` script from Bash to GNU Guile Scheme. This change aims to address the increasing complexity of the script and leverage the benefits of a more powerful programming language.
-
-## 1. Introduction: Why Guile Scheme?
-
-GNU Guile is the official extension language for the GNU Project. It is an implementation of the Scheme programming language, a dialect of Lisp. Using Guile for scripting offers several advantages over Bash, especially as scripts grow in size and complexity.
-
-Key reasons for considering Guile:
-
-* **Expressiveness and Power:** Scheme is a full-fledged programming language with features like first-class functions, macros, and a rich standard library. This allows for more elegant and maintainable solutions to complex problems.
-* **Better Error Handling:** Guile provides robust error handling mechanisms (conditions and handlers) that are more sophisticated than Bash's `set -e` and trap.
-* **Modularity:** Guile supports modules, making it easier to organize code into reusable components.
-* **Data Manipulation:** Scheme excels at handling structured data, which can be beneficial for managing configurations or parsing output from commands.
-* **Readability (for Lisp programmers):** While Lisp syntax can be initially unfamiliar, it can lead to very clear and concise code once learned.
-* **Interoperability:** Guile can easily call external programs and libraries, and can be extended with C code if needed.
-
-## 2. Advantages over Bash for `home-lab-tools`
-
-Migrating `home-lab-tools` from Bash to Guile offers specific benefits:
-
-* **Improved Logic Handling:** Complex conditional logic, loops, and function definitions are more naturally expressed in Guile. The current Bash script uses case statements and string comparisons extensively, which can become unwieldy.
-* **Structured Data Management:** Machine definitions, deployment modes, and status information could be represented as Scheme data structures (lists, association lists, records), making them easier to manage and query.
-* **Enhanced Error Reporting:** More descriptive error messages and better control over script termination in case of failures.
-* **Code Reusability:** Functions for common tasks (e.g., SSHing to a machine, running `nixos-rebuild`) can be more cleanly defined and reused.
-* **Easier Testing:** Guile's nature as a programming language makes it more amenable to unit testing individual functions or modules.
-* **Future Extensibility:** Adding new commands, machines, or features will be simpler and less error-prone in a more structured language.
-
-## 3. Setting up Guile
-
-Guile is often available through system package managers. On NixOS, it can be added to your environment or system configuration.
-
-```nix
-# Example: Adding Guile to a Nix shell
-nix-shell -p guile
-```
-
-A Guile script typically starts with a shebang line:
-
-```scheme
-#!/usr/bin/env guile
-!#
-```
-
-The `!#` at the end is a Guile-specific convention that allows the script to be both executable and loadable into a Guile REPL.
-
-## 4. Basic Guile Scripting Concepts
-
-* **S-expressions:** Code is written using S-expressions (Symbolic Expressions), which are lists enclosed in parentheses, e.g., `(function arg1 arg2)`.
-* **Definitions:** `(define variable value)` and `(define (function-name arg1 arg2) ...body...)`.
-* **Procedures (Functions):** Core of Guile programming.
-* **Control Flow:** `(if condition then-expr else-expr)`, `(cond (test1 expr1) (test2 expr2) ... (else else-expr))`, `(case ...)`
-* **Modules:** `(use-modules (ice-9 popen))` for using libraries.
-
-## 5. Interacting with the System
-
-Guile provides modules for system interaction:
-
-* **(ice-9 popen):** For running external commands and capturing their output (similar to backticks or `$(...)` in Bash).
-  * `open-pipe* command mode`: Opens a pipe to a command.
-  * `get-string-all port`: Reads all output from a port.
-* **(ice-9 rdelim):** For reading lines from ports.
-* **(ice-9 filesys):** For file system operations (checking existence, deleting, etc.).
-  * `file-exists? path`
-  * `delete-file path`
-* **(srfi srfi-1):** List processing utilities.
-* **(srfi srfi-26):** `cut` for partial application, useful for creating specialized functions.
-* **Environment Variables:** `(getenv "VAR_NAME")`, `(setenv "VAR_NAME" "value")`.
-
-## Example: Running a command**
-
-```scheme
-(use-modules (ice-9 popen))
-
-(define (run-command . args)
-  (let* ((cmd (string-join args " "))
-         (port (open-pipe* cmd OPEN_READ)))
-    (let ((output (get-string-all port)))
-      (close-pipe port)
-      output)))
-
-(display (run-command "echo" "Hello from Guile"))
-(newline)
-```
-
-## 6. Error Handling
-
-Guile uses a condition system for error handling.
-
-* `catch`: Allows you to catch specific types of errors.
-* `throw`: Raises an error.
-
-```scheme
-(use-modules (ice-9 exceptions))
-
-(catch #t
-  (lambda ()
-    (display "Trying something that might fail...
-")
-    ;; Example: Force an error
-    (if #t (error "Something went wrong!"))
-    (display "This won't be printed if an error occurs above.
-"))
-  (lambda (key . args)
-    (format (current-error-port) "Caught an error: ~a - Args: ~a
-" key args)
-    #f)) ; Return value indicating an error was caught
-```
-
-For `home-lab-tools`, this means we can provide more specific feedback when a deployment fails or a machine is unreachable.
-
-## 7. Modularity and Code Organization
-
-Guile's module system allows splitting the code into logical units. For `home-lab-tools`, we could have modules for:
-
-* `lab-config`: Machine definitions, paths.
-* `lab-deploy`: Functions related to deploying configurations.
-* `lab-ssh`: SSH interaction utilities.
-* `lab-status`: Functions for checking machine status.
-* `lab-utils`: General helper functions, logging.
-
-**Example module structure:**
-
-```scheme
-;; file: lab-utils.scm
-(define-module (lab utils)
-  #:export (log success warn error))
-
-(define blue "")
-(define nc "")
-
-(define (log msg)
-  (format #t "~a[lab]~a ~a
-" blue nc msg))
-;; ... other logging functions
-```
-
-```scheme
-;; file: main-lab-script.scm
-#!/usr/bin/env guile
-!#
-(use-modules (lab utils) (ice-9 popen))
-
-(log "Starting lab script...")
-;; ... rest of the script
-```
-
-## 8. Example: Rewriting a Small Part of `home-lab-tools.nix` (Conceptual)
-
-Let's consider the `log` function and a simplified `deploy_machine` for local deployment.
-
-**Current Bash:**
-
-```bash
-BLUE=''
-NC='' # No Color
-
-log() {
-  echo -e "''${BLUE}[lab]''${NC} $1"
-}
-
-deploy_machine() {
-  local machine="$1"
-  # ...
-  if [[ "$machine" == "congenital-optimist" ]]; then
-    log "Deploying $machine (mode: $mode) locally"
-    sudo nixos-rebuild $mode --flake "$HOMELAB_ROOT#$machine"
-  fi
-  # ...
-}
-```
-
-**Conceptual Guile Scheme:**
-
-```scheme
-;; main-lab-script.scm
-#!/usr/bin/env guile
-!#
-
-(use-modules (ice-9 popen)
-             (ice-9 rdelim)
-             (ice-9 pretty-print)
-             (ice-9 exceptions)
-             (srfi srfi-1)) ;; For list utilities like `string-join`
-
-;; Configuration (could be in a separate module)
-(define homelab-root "/home/geir/Home-lab")
-
-;; Color Definitions
-(define RED "")
-(define GREEN "")
-(define YELLOW "")
-(define BLUE "")
-(define NC "")
-
-;; Logging functions
-(define (log level-color level-name message)
-  (format #t "~a[~a]~a ~a
-" level-color level-name NC message))
-
-(define (info . messages)
-  (log BLUE "lab" (apply string-append (map (lambda (m) (if (string? m) m (format #f "~s" m))) messages))))
-
-(define (success . messages)
-  (log GREEN "lab" (apply string-append (map (lambda (m) (if (string? m) m (format #f "~s" m))) messages))))
-
-(define (warn . messages)
-  (log YELLOW "lab" (apply string-append (map (lambda (m) (if (string? m) m (format #f "~s" m))) messages))))
-
-(define (err . messages)
-  (log RED "lab" (apply string-append (map (lambda (m) (if (string? m) m (format #f "~s" m))) messages)))
-  (exit 1)) ;; Exit on error
-
-;; Function to run shell commands and handle output/errors
-(define (run-shell-command . command-parts)
-  (let ((command-string (string-join command-parts " ")))
-    (info "Executing: " command-string)
-    (let ((pipe (open-pipe* command-string OPEN_READ)))
-      (let loop ((lines '()))
-        (let ((line (read-line pipe)))
-          (if (eof-object? line)
-              (begin
-                (close-pipe pipe)
-                (reverse lines)) ;; Return lines in order
-              (begin
-                (display line) (newline) ;; Display live output
-                (loop (cons line lines)))))))
-    ;; TODO: Add proper error checking based on exit status of the command
-    ;; For now, we assume success if open-pipe* doesn't fail.
-    ;; A more robust solution would check `close-pipe` status or use `system*`.
-    ))
-
-;; Simplified deploy_machine
-(define (deploy-machine machine mode)
-  (info "Deploying " machine " (mode: " mode ")")
-  (cond
-    ((string=? machine "congenital-optimist")
-     (info "Deploying " machine " locally")
-     (catch #t
-       (lambda ()
-         (run-shell-command "sudo" "nixos-rebuild" mode "--flake" (string-append homelab-root "#" machine))
-         (success "Successfully deployed " machine))
-       (lambda (key . args)
-         (err "Failed to deploy " machine ". Error: " key " Args: " args))))
-    ;; Add other machines here
-    (else
-     (err "Unknown machine: " machine))))
-
-;; Main script logic (parsing arguments, calling functions)
-(define (main args)
-  (if (< (length args) 3)
-      (begin
-        (err "Usage: <script> deploy <machine> [mode]")
-        (exit 1))
-      (let ((command (cadr args))
-            (machine (caddr args))
-            (mode (if (> (length args) 3) (cadddr args) "boot")))
-        (cond
-          ((string=? command "deploy")
-           (deploy-machine machine mode))
-          ;; Add other commands like "status", "update"
-          (else
-           (err "Unknown command: " command))))))
-
-;; Run the main function with command-line arguments
-;; (cdr args) to skip the script name itself
-(main (program-arguments))

-## 9. Creating Terminal User Interfaces (TUIs) with Guile-Ncurses
-
-For more interactive command-line tools, Guile Scheme can be used to create Text User Interfaces (TUIs). The primary library for this is `guile-ncurses`.
-
-**Guile-Ncurses** is a GNU project that provides Scheme bindings for the ncurses library, including its components for forms, panels, and menus. This allows you to build sophisticated text-based interfaces directly in Guile.
-
-**Key Features:**
-
-* **Windowing:** Create and manage multiple windows on the terminal.
-* **Input Handling:** Process keyboard input, including special keys.
-* **Text Attributes:** Control colors, bolding, underlining, and other text styles.
-* **Forms, Panels, Menus:** Higher-level components for building complex interfaces.
-
-**Getting Started with Guile-Ncurses:**
-
-1. **Installation:** `guile-ncurses` would typically be installed via your system's package manager or built from source. If you are using NixOS, you would look for a Nix package for `guile-ncurses`.
-
-    ```nix
-    # Example: Adding guile-ncurses to a Nix shell (package name might vary)
-    nix-shell -p guile guile-ncurses
-    ```
-
-2. **Using in Code:**
-    You would use the `(ncurses curses)` module (and others like `(ncurses form)`, `(ncurses menu)`, `(ncurses panel)`) in your Guile script.
-
-    ```scheme
-    (use-modules (ncurses curses))
-
-    (define (tui-main stdscr)
-      ;; Initialize ncurses
-      (cbreak!)       ;; Line buffering disabled, Pass on ever char
-      (noecho!)       ;; Don't echo() while we do getch
-      (keypad stdscr #t) ;; Enable Fx keys, arrow keys etc.
-
-      (addstr "Hello, Guile Ncurses TUI!")
-      (refresh)
-      (getch) ;; Wait for a key press
-      (endwin)) ;; End curses mode
-
-    ;; Initialize and run the TUI
-    (initscr)
-    (tui-main stdscr)
-    ```
-
-**Resources:**
-
-* **Guile-Ncurses Project Page:** [https://www.nongnu.org/guile-ncurses/](https://www.nongnu.org/guile-ncurses/)
-* **Guile-Ncurses Manual:** [https://www.gnu.org/software/guile-ncurses/manual/](https://www.gnu.org/software/guile-ncurses/manual/)
-
-Integrating `guile-ncurses` can significantly enhance the user experience of your `home-lab-tools` script, allowing for interactive menus, status dashboards, and more complex user interactions beyond simple command-line arguments and output.
-
-## 10. Conclusion and Next Steps
-
-Migrating `home-lab-tools` to Guile Scheme offers a path to a more maintainable, robust, and extensible solution. While there is a learning curve for Scheme, the long-term benefits for managing a complex set of administration tasks are significant.
-
-**Next Steps:**
-
-1. **Install Guile:** Ensure Guile is available in the development environment.
-2. **Start Small:** Begin by porting one command or a set of utility functions (e.g., logging, SSH wrappers).
-3. **Learn Guile Basics:** Familiarize with Scheme syntax, common procedures, and modules. The Guile Reference Manual is an excellent resource.
-4. **Develop Incrementally:** Port functionality piece by piece, testing along the way.
-5. **Explore Guile Libraries:** Investigate Guile libraries for argument parsing (e.g., `(gnu cmdline)`), file system operations, and other needs.
-6. **Refactor and Organize:** Use Guile's module system to keep the codebase clean and organized.
-
-This transition will require an initial investment in learning and development but promises a more powerful and sustainable tool for managing the home lab infrastructure.

-# Lab Tool Testing
-
-This directory contains all test files for the lab tool, organized using TDD principles.
-
-## Test Categories
-
-### Core Functionality Tests
-- `test-functionality.scm` - Basic functionality verification
-- `test-main.scm` - Main CLI interface tests
-- `test-deployment.scm` - Deployment module tests
-- `test-missing-functions.scm` - Missing function implementation tests
-
-### Integration Tests
-- `test-integration.scm` - End-to-end integration tests
-- `test-modules-simple.scm` - Simple module loading tests
-
-### Implementation Tests
-- `test-implementation.scm` - Implementation-specific tests
-- `test-modular.scm` - Modular architecture tests
-
-### Validation Tests
-- `test-final-validation.scm` - Final validation suite
-- `final-verification.scm` - Complete functionality verification
-- `tdd-summary.scm` - TDD completion summary
-
-## Running Tests
-
-To avoid compilation issues with Guile, run tests with:
-
-```bash
-GUILE_AUTO_COMPILE=0 guile <test-file>
-```
-
-## Test Results Summary
-
-✅ All core functionality working:
-- CLI interface (help, status, machines, deploy, health)
-- Deployment to actual machines
-- Infrastructure monitoring
-- Error handling
-- Modular architecture
-
-## K.I.S.S Principles Applied
-
-- One test per functionality
-- Simple test framework
-- Clear test descriptions
-- Fast feedback loops
