CHANGE 1: Add Logging Function Fallback Support
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

Location: Lines 96-116 (Early in script, right after assembly imports)

Original:
  try {
      $scriptRoot = Split-Path -Parent $MyInvocation.MyCommand.Path
      if (Test-Path "$scriptRoot\ErrorLogging.ps1") {
          . "$scriptRoot\ErrorLogging.ps1"
          $null = Initialize-ErrorLogging -ScriptRoot $scriptRoot -RetentionDays 7
          Add-MiracleBootLog -Level "INFO" -Message "WinRepairGUI.ps1 loaded" -Location "WinRepairGUI.ps1"
      }
  } catch {
      # Silently continue if logging fails
  }

Changed to:
  try {
      $scriptRoot = Split-Path -Parent $MyInvocation.MyCommand.Path
      if (Test-Path "$scriptRoot\ErrorLogging.ps1") {
          . "$scriptRoot\ErrorLogging.ps1"
          $null = Initialize-ErrorLogging -ScriptRoot $scriptRoot -RetentionDays 7
          try { Add-MiracleBootLog -Level "INFO" -Message "WinRepairGUI.ps1 loaded" -Location "WinRepairGUI.ps1" -ErrorAction SilentlyContinue } catch { $script:LoggingAvailable = $false }
          $script:LoggingAvailable = $true
      } else {
          # Fallback if ErrorLogging.ps1 not found - define stub function
          if (-not (Get-Command Add-MiracleBootLog -ErrorAction SilentlyContinue)) {
              function Add-MiracleBootLog {
                  param([string]$Level, [string]$Message, [string]$Location, [switch]$NoConsole, [hashtable]$Data, [switch]$ErrorAction)
                  # Stub function - does nothing, just prevents errors
              }
          }
      }
  } catch {
      # Silently continue if logging fails - define stub
      if (-not (Get-Command Add-MiracleBootLog -ErrorAction SilentlyContinue)) {
          function Add-MiracleBootLog {
              param([string]$Level, [string]$Message, [string]$Location, [switch]$NoConsole, [hashtable]$Data, [switch]$ErrorAction)
              # Stub function - does nothing, just prevents errors
          }
      }
  }

Reason: ErrorLogging.ps1 file is missing, so Add-MiracleBootLog would be undefined,
        causing GUI to fail. This creates a stub function as fallback.

================================================================================

CHANGE 2: Add Window Null Validation
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

Location: Line 349-352 (Right after XAML parsing)

Original:
  # #region agent log
  try {
      ...
  }
  # #endregion agent log
  
  $envStatusControl = Get-Control -Name "EnvStatus"

Changed to:
  # Validate window object is valid before accessing controls
  if ($null -eq $W) {
      throw "Window object is null - XAML parsing may have failed silently"
  }
  
  # #region agent log
  try {
      ...
  }
  # #endregion agent log
  
  $envStatusControl = Get-Control -Name "EnvStatus"

Reason: Prevents accessing methods on null window object if XAML parsing silently fails.

================================================================================

CHANGE 3: Replace FindName Calls with Get-Control Helper
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

Locations: Multiple (approx 8+ replacements)
  - Line 357: EnvStatus
  - Line 381: BtnNotepad
  - Line 394: BtnRegistry
  - Line 407: BtnPowerShell
  - Line 420: BtnDiskManagement
  - Line 433: BtnRestartExplorer
  - Line 482: BtnEnableNetwork

Example change (BtnNotepad at line 381):

Original:
  $btnNotepad = $W.FindName("BtnNotepad")
  if ($btnNotepad) {

Changed to:
  $btnNotepad = Get-Control -Name "BtnNotepad"
  if ($btnNotepad) {

Reason: Get-Control provides null checking and logging. Direct FindName calls
        would fail silently if control doesn't exist.

================================================================================

CHANGE 4: Fix Event Handler Structure - BtnChkTestMode
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

Location: Lines ~2533

Original:
  $testMode = $W.FindName("ChkTestMode").IsChecked

Changed to:
  $chkTestMode = Get-Control -Name "ChkTestMode"
  $testMode = if ($chkTestMode) { $chkTestMode.IsChecked } else { $false }

Reason: Prevents null reference exception if control doesn't exist.

================================================================================

CHANGE 5: Fix BtnBCD RaiseEvent Calls
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

Locations: Lines 1517-1523, 1768

Original:
  $W.FindName("BtnBCD").RaiseEvent([System.Windows.RoutedEventArgs]::new([System.Windows.Controls.Button]::ClickEvent))

Changed to:
  $bcdBtn = Get-Control -Name "BtnBCD"
  if ($bcdBtn) {
      $bcdBtn.RaiseEvent([System.Windows.RoutedEventArgs]::new([System.Windows.Controls.Button]::ClickEvent))
  }

Reason: Check if button exists before raising events.

================================================================================

CHANGE 6: Fix LogAnalysisBox Update
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

Location: Line 4562

Original:
  $W.FindName("LogAnalysisBox").Text += "`n`n[ERROR] Failed: $_`n"

Changed to:
  $logBox = Get-Control -Name "LogAnalysisBox"
  if ($logBox) {
      $logBox.Text += "`n`n[ERROR] Failed: $_`n"
  }

Reason: Prevent null reference if control not found.

================================================================================

CHANGE 7: Fix RadioButton Event Handlers
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

Location: Lines ~4592-4635

Original:
  $W.FindName("RbOnlineMode").Add_Checked({
      if ($W.FindName("RbOnlineMode").IsChecked) {
          $W.FindName("RepairModeDescription").Text = "..."
          $W.FindName("OfflineDrivePanel").Visibility = "Collapsed"
      }
  })
  
  $W.FindName("RbOfflineMode").Add_Checked({
      if ($W.FindName("RbOfflineMode").IsChecked) {
          $W.FindName("RepairModeDescription").Text = "..."
          $W.FindName("OfflineDrivePanel").Visibility = "Visible"
          $W.FindName("RepairOfflineDrive").Items.Clear()
          ...
      }
  })

Changed to:
  $rbOnlineMode = Get-Control -Name "RbOnlineMode"
  if ($rbOnlineMode) {
      $rbOnlineMode.Add_Checked({
          $rb = Get-Control -Name "RbOnlineMode"
          $desc = Get-Control -Name "RepairModeDescription"
          $offlinePanel = Get-Control -Name "OfflineDrivePanel"
          if ($rb -and $rb.IsChecked) {
              if ($desc) { $desc.Text = "This forces Setup..." }
              if ($offlinePanel) { $offlinePanel.Visibility = "Collapsed" }
          }
      })
  }
  
  [Similar pattern for RbOfflineMode]

Reason: Multiple controls accessed without null checks. Now all protected.

================================================================================

CHANGE 8: Fix TxtTimeout Access
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

Location: Lines ~1826

Original:
  $t = $W.FindName("TxtTimeout").Text
  bcdedit /timeout $t
  [System.Windows.MessageBox]::Show(...)

Changed to:
  $txtTimeout = Get-Control -Name "TxtTimeout"
  if ($txtTimeout) {
      $t = $txtTimeout.Text
      bcdedit /timeout $t
      [System.Windows.MessageBox]::Show(...)
  } else {
      [System.Windows.MessageBox]::Show("Timeout control not found.", "Error", "OK", "Error")
  }

Reason: Check control exists before accessing properties.

================================================================================

CHANGE 9: Fix BtnAdvancedControllerDetection Handler
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

Location: Lines ~2088-2160

Original:
  if ($W.FindName("BtnAdvancedControllerDetection")) {
      $btnAdvancedControllerDetection = Get-Control -Name "BtnAdvancedControllerDetection"
      if ($btnAdvancedControllerDetection) {
          $btnAdvancedControllerDetection.Add_Click({
              ...
          })
      }
  }

Changed to:
  $btnAdvancedControllerDetection = Get-Control -Name "BtnAdvancedControllerDetection"
  if ($btnAdvancedControllerDetection) {
      $btnAdvancedControllerDetection.Add_Click({
          ...
      })
  }

Also removed extra closing brace on line 2160 (was: } } })

Reason: Simplify structure - one FindName check instead of two.
        Also fixes brace mismatch that was causing parse error.

================================================================================

CHANGE 10: Fix BtnAdvancedDriverInjection Handler
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

Location: Lines ~2155-2327

Original:
  if ($W.FindName("BtnAdvancedDriverInjection")) {
      $btnAdvancedDriverInjection = Get-Control -Name "BtnAdvancedDriverInjection"
      if ($btnAdvancedDriverInjection) {
          $btnAdvancedDriverInjection.Add_Click({
              ...
          })
      }
  }

Changed to:
  $btnAdvancedDriverInjection = Get-Control -Name "BtnAdvancedDriverInjection"
  if ($btnAdvancedDriverInjection) {
      $btnAdvancedDriverInjection.Add_Click({
          ...
      })
  }

Also removed extra closing brace on line 2327

Reason: Same as BtnAdvancedControllerDetection - simplify and fix brace mismatch.

================================================================================

CHANGE 11: Fix BtnFindMatchingDrivers Handler
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

Location: Lines ~2226

Original:
  if ($W.FindName("BtnFindMatchingDrivers")) {
      $btnFindMatchingDrivers = Get-Control -Name "BtnFindMatchingDrivers"
      if ($btnFindMatchingDrivers) {
          $btnFindMatchingDrivers.Add_Click({

Changed to:
  $btnFindMatchingDrivers = Get-Control -Name "BtnFindMatchingDrivers"
  if ($btnFindMatchingDrivers) {
      $btnFindMatchingDrivers.Add_Click({

Also removed extra closing brace

Reason: Consistent with other handler fixes.

================================================================================
