Subject: [PATCH 03/34] Integrate Guidelines shared WPF library v1.0.0

- Add Guidelines project to solution
- Reference ZBitSystems.Wpf.UI in Windows project
- Update App.xaml to use shared design system via pack URIs
- Remove migrated files: DesignTokens, ThemeSemanticColors, ComponentStyles, CopyTextBoxHelper
- Keep LayoutTemplates.xaml (OSDP-specific, not migrated)
- Update CLAUDE.md with submodule workflow documentation

Phase 1 Complete: Design system and CopyTextBoxHelper migrated to shared library.
All pages render correctly, theme switching works, no visual regressions.

Build: Success (0 errors, 13 warnings - all XML docs in Guidelines library)
Code Inspection: Clean (no new warnings in OSDP-Bench code)

+## Shared UI Components
+
+This project uses the [Guidelines](https://github.com/Z-bit-Systems-LLC/Guidelines) shared WPF library for design system components.
+
+### Working with the Guidelines Submodule
+
+**Initial clone (new developers):**
+```bash
+git clone --recursive https://github.com/Z-bit-Systems-LLC/OSDP-Bench.git
+```
+
+**Update Guidelines to latest version:**
+```bash
+git submodule update --remote lib/Guidelines
+git add lib/Guidelines
+git commit -m "Update Guidelines submodule to latest version"
+```
+
+**Making changes to Guidelines:**
+If you need to modify the shared library:
+1. Make changes in `lib/Guidelines/`
+2. Test changes in OSDP-Bench (local project reference)
+3. Commit and push in Guidelines repository
+4. Update submodule reference in OSDP-Bench
+
+### Design System Reference
+See `lib/Guidelines/src/ZBitSystems.Wpf.UI/Styles/StyleGuide.md` for:
+- Available styles and design tokens
+- Standard components and layouts
+- Theme-aware semantic colors
+- Usage examples and best practices
+
 ## UI Style Guidelines
 - **Always use standard styles** - Apply predefined styles from the design system instead of inline properties
 - **Use design tokens for spacing** - Reference `{StaticResource Margin.Card}` instead of hardcoding values

 - **Use WrapPanel for responsive layouts** - When controls should be horizontal on wide screens but wrap to vertical on narrow screens, use WrapPanel instead of fixed Grid layouts
 - **Prefer dynamic resources for colors** - Use `{DynamicResource}` instead of `{StaticResource}` for colors to ensure theme compatibility

Subject: [PATCH 04/34] Remove duplicate StyleGuide.md

StyleGuide.md is now maintained in the Guidelines shared library at:
lib/Guidelines/src/ZBitSystems.Wpf.UI/Styles/StyleGuide.md

ExampleImplementation.md remains in OSDP-Bench as it contains
application-specific implementation examples.

-# OSDP Bench UI Style Guide
-
-## Overview
-This style guide provides a comprehensive design system for OSDP Bench, ensuring visual consistency and maintainability across the application.
-
-## Design System Structure
-
-### 1. Design Tokens (`DesignTokens.xaml`)
-Foundation values for spacing, typography, colors, and sizing.
-
-#### Spacing System (8px grid)
-```xml
-{StaticResource Spacing.XSmall}    <!-- 4px -->
-{StaticResource Spacing.Small}     <!-- 8px -->
-{StaticResource Spacing.Medium}    <!-- 16px -->
-{StaticResource Spacing.Large}     <!-- 24px -->
-{StaticResource Spacing.XLarge}    <!-- 32px -->
-{StaticResource Spacing.XXLarge}   <!-- 48px -->
-```
-
-#### Standard Margins & Padding
-```xml
-{StaticResource Margin.Card}       <!-- 10,5 -->
-{StaticResource Margin.Control}    <!-- 0,0,16,0 -->
-{StaticResource Margin.Button}     <!-- 8,4 -->
-{StaticResource Padding.Card}      <!-- 16 -->
-{StaticResource Padding.Control}   <!-- 8,4 -->
-```
-
-#### Typography Scale
-```xml
-{StaticResource FontSize.Caption}  <!-- 12px -->
-{StaticResource FontSize.Body}     <!-- 14px -->
-{StaticResource FontSize.BodyLarge} <!-- 16px -->
-{StaticResource FontSize.Subtitle} <!-- 20px -->
-{StaticResource FontSize.Title}    <!-- 24px -->
-{StaticResource FontSize.Headline} <!-- 32px -->
-{StaticResource FontSize.Display}  <!-- 36px -->
-```
-
-### 2. Component Styles (`ComponentStyles.xaml`)
-Reusable styles for UI components.
-
-#### Typography Usage
-```xml
-<!-- Page titles -->
-<TextBlock Style="{StaticResource Page.Title}" Text="Page Name"/>
-
-<!-- Section headers -->
-<TextBlock Style="{StaticResource Text.Title}" Text="Section"/>
-
-<!-- Body text -->
-<TextBlock Style="{StaticResource Text.Body}" Text="Content"/>
-
-<!-- Status messages -->
-<TextBlock Style="{StaticResource Text.Error}" Text="Error message"/>
-<TextBlock Style="{StaticResource Text.Warning}" Text="Warning"/>
-<TextBlock Style="{StaticResource Text.Success}" Text="Success"/>
-```
-
-#### Form Controls
-```xml
-<!-- Labels -->
-<Label Style="{StaticResource Label.Standard}" Content="Field Name"/>
-
-<!-- Text boxes -->
-<TextBox Style="{StaticResource TextBox.Standard}"/>
-
-<!-- Read-only text boxes (includes gray background, copy button, disabled context menu) -->
-<TextBox IsReadOnly="True" Style="{StaticResource TextBox.Standard}"/>
-
-<!-- Combo boxes -->
-<ComboBox Style="{StaticResource ComboBox.Standard}"/>
-
-<!-- Number boxes -->
-<ui:NumberBox Style="{StaticResource NumberBox.Standard}"/>
-```
-
-#### Buttons
-```xml
-<!-- Primary actions -->
-<ui:Button Style="{StaticResource Button.Primary}" Content="Save"/>
-
-<!-- Secondary actions -->
-<ui:Button Style="{StaticResource Button.Secondary}" Content="Cancel"/>
-
-<!-- Transparent/subtle actions -->
-<ui:Button Style="{StaticResource Button.Transparent}" Content="Browse"/>
-```
-
-#### Badges
-Status badges for displaying security states and status indicators.

-**Badge Styles:**
-- `Badge.Success` / `Badge.Success.Small` - Green filled (secure/positive states)
-- `Badge.Info` / `Badge.Info.Small` - Blue filled (informational states)
-- `Badge.Warning` / `Badge.Warning.Small` - Orange filled (warning states)
-- `Badge.Error.Outlined` / `Badge.Error.Outlined.Small` - Red outlined (error/insecure states)
-
-**Badge Text Styles:**
-- `Badge.Text` / `Badge.Text.Small` - White text for filled badges
-- `Badge.Text.Error` / `Badge.Text.Error.Small` - Red text for outlined error badges
-
-### 3. Layout Templates (`LayoutTemplates.xaml`)
-Templates for common layout patterns.
-
-#### Page Structure
-```xml
-<!-- Page container -->
-<StackPanel Style="{StaticResource Page.Container}">
-    <!-- Page header with activity indicators -->
-    <ContentControl Content="Page Title" 
-                    Template="{StaticResource Template.PageHeader}"/>
-    
-    <!-- Content cards -->
-    <ui:Card Style="{StaticResource Card.Standard}">
-        <StackPanel Style="{StaticResource Card.Content}">
-            <!-- Card content -->
-        </StackPanel>
-    </ui:Card>
-</StackPanel>
-```
-
-#### Data Grids
-```xml
-<!-- Standard data grid -->
-<DataGrid Style="{StaticResource DataGrid.Standard}">
-    <!-- Columns -->
-</DataGrid>
-
-<!-- Monitor page data grid -->
-<DataGrid Style="{StaticResource DataGrid.Monitor}">
-    <!-- Columns -->
-</DataGrid>
-```
-
-## Implementation Guidelines
-
-### 1. Migration Strategy
-1. **Immediate adoption**: Use new styles for all new components
-2. **Gradual migration**: Update existing components when making changes
-3. **Legacy support**: Existing `PageTitleStyle` remains functional
-
-### 2. Best Practices
-
-#### ✅ Do
-- Use design tokens for spacing: `Margin="{StaticResource Margin.Card}"`
-- Apply semantic color styles: `Style="{StaticResource Text.Error}"`
-- Follow typography hierarchy: Display → Headline → Title → Subtitle → Body
-- Use standard component styles for consistency
-- Leverage layout templates for common patterns
-
-#### ❌ Don't
-- Use hardcoded margins/padding values
-- Mix explicit FontSize with typography styles
-- Use hardcoded colors (Red, Orange, etc.)
-- Create one-off styles without considering reusability
-- Override TextBox MinHeight in normal layouts (use design tokens instead)
-- Use StaticResource syntax within Thickness strings (e.g., `"0,0,0,{StaticResource Spacing.Medium}"`)
-
-#### Special Cases
-```xml
-<!-- Height-sensitive containers (DockPanel) - override TextBox MinHeight -->
-<TextBox Style="{StaticResource TextBox.Standard}"
-         MinHeight="0" Height="Auto" VerticalAlignment="Center"/>
-
-<!-- DataGrid with invisible selection -->
-<ui:DataGrid CanUserSortColumns="False">
-    <ui:DataGrid.RowStyle>
-        <Style TargetType="DataGridRow">
-            <Style.Triggers>
-                <Trigger Property="IsSelected" Value="True">
-                    <Setter Property="Background" Value="Transparent"/>
-                    <Setter Property="BorderBrush" Value="Transparent"/>
-                </Trigger>
-            </Style.Triggers>
-        </Style>
-    </ui:DataGrid.RowStyle>
-    <ui:DataGrid.CellStyle>
-        <Style TargetType="DataGridCell">
-            <Style.Triggers>
-                <Trigger Property="IsSelected" Value="True">
-                    <Setter Property="Background" Value="Transparent"/>
-                    <Setter Property="BorderBrush" Value="Transparent"/>
-                    <Setter Property="Foreground" Value="{DynamicResource TextFillColorPrimaryBrush}"/>
-                </Trigger>
-            </Style.Triggers>
-        </Style>
-    </ui:DataGrid.CellStyle>
-</ui:DataGrid>
-```
-
-### 3. Common Patterns
-
-#### Form Layout
-```xml
-<StackPanel Style="{StaticResource Section.Container}">
-    <ui:TextBlock Style="{StaticResource Section.Header}" 
-                  Text="{markup:Localize Section_Title}"/>
-    
-    <!-- Form fields -->
-    <ContentControl Tag="{markup:Localize Field_Label}"
-                    Template="{StaticResource Template.FormField}">
-        <TextBox Style="{StaticResource TextBox.Standard}"/>
-    </ContentControl>
-</StackPanel>
-```
-
-#### Status Messages
-```xml
-<TextBlock Text="{Binding StatusMessage}">
-    <TextBlock.Style>
-        <Style TargetType="TextBlock" BasedOn="{StaticResource Text.Body}">
-            <Style.Triggers>
-                <DataTrigger Binding="{Binding StatusLevel}" Value="Error">
-                    <Setter Property="Foreground" Value="{StaticResource Brush.Error}"/>
-                </DataTrigger>
-                <!-- Additional triggers -->
-            </Style.Triggers>
-        </Style>
-    </TextBlock.Style>
-</TextBlock>
-```
-
-### 4. Color System
-
-#### Semantic Colors
-- `{StaticResource Brush.Success}` - Green (#107C10)
-- `{StaticResource Brush.Warning}` - Orange (#FF8C00)  
-- `{StaticResource Brush.Error}` - Red (#D13438)
-- `{StaticResource Brush.Info}` - Blue (#0078D4)
-
-#### Activity Colors
-- `{StaticResource Brush.Activity.Tx}` - Transmit activity
-- `{StaticResource Brush.Activity.Rx}` - Receive activity
-- `{StaticResource Brush.Activity.Inactive}` - Inactive state
-
-#### Theme-Aware Colors (Recommended)
-- `{DynamicResource TextFillColorPrimaryBrush}` - Primary text
-- `{DynamicResource TextFillColorSecondaryBrush}` - Secondary text
-- `{DynamicResource ControlFillColorDefaultBrush}` - Control backgrounds
-
-## Future Enhancements
-
-### Planned Additions
-1. **Animation system** - Consistent transitions and micro-interactions
-2. **Responsive breakpoints** - Adaptive layouts for different window sizes
-3. **Dark mode optimizations** - Enhanced dark theme color palette
-4. **Accessibility styles** - High contrast and screen reader optimizations
-
-### Maintenance
-- Review and update design tokens quarterly
-- Add new component styles as needed
-- Maintain backwards compatibility for existing styles
-- Document any breaking changes in component updates

Subject: [PATCH 06/34] Fix: Remove obsolete resource references from
 LayoutTemplates.xaml

LayoutTemplates.xaml was trying to load DesignTokens.xaml and
ComponentStyles.xaml from local Styles directory, but these files
were migrated to Guidelines library.

These resources are now loaded via App.xaml from the Guidelines library,
so LayoutTemplates.xaml inherits them automatically through WPF's
resource lookup hierarchy.

Fixes runtime error: Cannot locate resource 'styles/designtokens.xaml'

Subject: [PATCH 07/34] Phase 2: Migrate generic converters to Guidelines
 library

Converters migrated (5):
- BooleanToVisibilityConverter
- InverseBoolConverter
- NullToVisibilityConverter
- StringToVisibilityConverter
- IndexToVisibilityConverter

StatusLevelConverter remains in OSDP-Bench (application-specific).

Changes:
- Update Guidelines submodule to include converters and tests
- Remove migrated converter files from OSDP-Bench
- Update converter namespace in 4 XAML files to reference Guidelines library
- Add dual namespace support for shared and local converters in ConfigurationPage

Build: Success (0 errors, 0 warnings)
Tests: All 39 Guidelines library tests passing
Application: Verified running successfully

Subject: [PATCH 09/34] Integrate Guidelines window and theme management

- Update Guidelines submodule to include window/theme management
- Create UserSettingsWindowStateAdapter to keep Core UI-independent
- Refactor MainWindow to use WindowStateManager from Guidelines
- Refactor InfoPage to use ThemeManager from Guidelines
- Remove custom window state persistence code (now in Guidelines)

Architecture improvement:
- Core project remains UI-independent (targets net10.0)
- Adapter pattern used to bridge Core types with Guidelines interfaces

-# Language Switching UI Implementation
-
-## ✅ Implementation Complete!
-
-The UI language switching functionality has been successfully implemented in OSDP-Bench. Users can now change the application language dynamically through the UI.
-
-## 🎯 Features Implemented
-
-### **1. Language Selection UI**
-- **Location**: Language selector in the main window title bar
-- **Control**: ComboBox showing available languages with native names
-- **Tooltip**: Helpful tooltip showing "Select Language"
-
-### **2. Supported Languages**
-Currently configured for:
-- **English** (en-US) - Fully implemented
-- **Spanish** (es-ES) - Sample translations provided
-- **French** (fr-FR) - Ready for translation
-- **German** (de-DE) - Ready for translation  
-- **Japanese** (ja-JP) - Ready for translation
-
-### **3. Dynamic UI Updates**
-- **Real-time switching**: UI updates immediately when language is changed
-- **All components respond**: XAML bindings, ViewModels, and code-behind all update
-- **Persistent selection**: Selected language is maintained during app session
-- **Error handling**: Graceful fallback to English if translation fails
-
-## 🛠️ Technical Implementation
-
-### **Architecture Components:**
-
-#### **LanguageSelectionViewModel**
-```csharp
-public partial class LanguageSelectionViewModel : ObservableObject
-{
-    public ObservableCollection<LanguageItem> AvailableLanguages { get; }
-    [ObservableProperty] private LanguageItem? _selectedLanguage;
-    
-    // Automatically triggers language change when selection changes
-    partial void OnSelectedLanguageChanged(LanguageItem? value) { ... }
-}
-```
-
-#### **Enhanced Resources Class**
-```csharp
-public class Resources : INotifyPropertyChanged
-{
-    public static event PropertyChangedEventHandler? PropertyChanged;
-    public static void ChangeCulture(CultureInfo newCulture) { ... }
-    public static string GetString(string key) { ... }
-}
-```
-
-#### **Dynamic LocalizeExtension**
-- Creates bindings that automatically update when culture changes
-- Uses `LocalizedStringBinding` for live UI updates
-- Fallback to static strings if binding fails
-
-#### **Enhanced LocalizationService**
-```csharp
-public interface ILocalizationService
-{
-    void ChangeCulture(CultureInfo culture);
-    void ChangeCulture(string cultureName);
-    event EventHandler<CultureInfo>? CultureChanged;
-}
-```
-
-### **UI Integration:**
-
-#### **MainWindow.xaml**
-```xml
-<ui:TitleBar.Header>
-    <StackPanel Orientation="Horizontal">
-        <TextBlock Text="{markup:Localize Language_Selection}"/>
-        <ComboBox ItemsSource="{Binding LanguageViewModel.AvailableLanguages}"
-                  SelectedItem="{Binding LanguageViewModel.SelectedLanguage, Mode=TwoWay}"/>
-    </StackPanel>
-</ui:TitleBar.Header>
-```
-
-#### **Dependency Injection**
-```csharp
-services.AddSingleton<ILocalizationService, LocalizationService>();
-```
-
-## 🧪 How to Test
-
-### **1. Using the UI (when Windows project runs):**
-1. Open the application
-2. Look for the "Language" dropdown in the title bar
-3. Select "Español" from the dropdown
-4. Watch as the UI elements update to Spanish
-5. Navigate between pages to see consistent translation
-
-### **2. Programmatically:**
-```csharp
-var localizationService = serviceProvider.GetService<ILocalizationService>();
-localizationService.ChangeCulture("es-ES"); // Switch to Spanish
-localizationService.ChangeCulture("en-US"); // Switch back to English
-```
-
-## 📊 Sample Translations Provided
-
-The Spanish resource file (`Resources.es.resx`) includes sample translations for:
-- **Connection Status**: Connected → Conectado, Disconnected → Desconectado
-- **Page Titles**: Connect → Conectar, Manage → Gestionar, Monitor → Monitor
-- **Navigation**: Connect to PD → Conectar a PD
-- **UI Elements**: Language → Idioma, Select Language → Seleccionar idioma
-
-## 🚀 Ready for Production
-
-### **To add new languages:**
-1. Create new resource file: `Resources.[culture].resx` (e.g., `Resources.fr.resx`)
-2. Add translations for all keys from the main `Resources.resx`
-3. The language will automatically appear in the dropdown
-
-### **Translation workflow:**
-1. Export main `Resources.resx` keys
-2. Send to translators
-3. Import translated strings into culture-specific files
-4. Deploy and test
-
-## 🎯 Next Steps Available
-
-1. **Culture Persistence**: Save user's language preference to settings
-2. **Translation Management**: Build tools for managing translations
-3. **RTL Support**: Add right-to-left language support
-4. **Professional Translation**: Replace sample translations with professional ones
-
-The language switching infrastructure is production-ready and easily extensible for additional languages and features!

-# Language Switching UI Build Fix
-
-## ❌ Issue Identified
-**Error**: `'ResourceDictionary' does not contain a definition for 'PropertyChanged'`
-
-**Root Cause**: In WPF applications, when you use `Resources.PropertyChanged`, the compiler interprets `Resources` as the WPF built-in `Resources` property (which is a `ResourceDictionary`) instead of our custom `OSDPBench.Core.Resources.Resources` class.
-
-## ✅ Fix Applied
-
-### **Files Fixed:**
-
-#### **1. ConnectPage.xaml.cs**
-```csharp
-// BEFORE (❌ Error)
-Resources.PropertyChanged += OnResourcesPropertyChanged;
-
-// AFTER (✅ Fixed)
-OSDPBench.Core.Resources.Resources.PropertyChanged += OnResourcesPropertyChanged;
-```
-
-#### **2. LocalizedStringBinding.cs**
-```csharp
-// BEFORE (❌ Error)
-Resources.PropertyChanged += OnResourcesPropertyChanged;
-public string Value => Resources.GetString(_key);
-Resources.PropertyChanged -= OnResourcesPropertyChanged;
-
-// AFTER (✅ Fixed)
-OSDPBench.Core.Resources.Resources.PropertyChanged += OnResourcesPropertyChanged;
-public string Value => OSDPBench.Core.Resources.Resources.GetString(_key);
-OSDPBench.Core.Resources.Resources.PropertyChanged -= OnResourcesPropertyChanged;
-```
-
-#### **3. Cleanup**
-- Removed unnecessary `using OSDPBench.Core.Resources;` statements
-- Used fully qualified names to avoid ambiguity
-
-## 🎯 Resolution Strategy
-
-### **Why This Happens:**
-In WPF, every `FrameworkElement` has a `Resources` property of type `ResourceDictionary`. When we wrote:
-```csharp
-Resources.PropertyChanged += ...
-```
-The compiler thought we meant:
-```csharp
-this.Resources.PropertyChanged += ...  // ResourceDictionary doesn't have PropertyChanged!
-```
-
-### **Solution:**
-Use fully qualified class names to be explicit:
-```csharp
-OSDPBench.Core.Resources.Resources.PropertyChanged += ...
-```
-
-## ✅ Verification
-
-### **Build Status:**
-- ✅ Core project builds successfully
-- ✅ All 58 tests pass
-- ✅ No compilation errors
-- ✅ Dynamic language switching functionality intact
-- ✅ UI binding system working correctly
-
-### **Components Verified:**
-- ✅ Resources class with INotifyPropertyChanged
-- ✅ LocalizedStringBinding for dynamic updates
-- ✅ ConnectPage dynamic property updates
-- ✅ LanguageSelectionViewModel (was already correct)
-
-## 🚀 Result
-
-The UI language switching system now builds correctly and is ready for use! The namespace collision issue has been resolved while maintaining all the dynamic functionality.
-
-### **Key Learning:**
-When working with WPF applications that have custom `Resources` classes, always use fully qualified names to avoid conflicts with the built-in WPF `Resources` property.

Subject: [PATCH 15/34] Replace custom user settings with Guidelines shared
 implementation

Eliminate duplicated JSON persistence logic and the UserSettingsWindowStateAdapter
by leveraging Guidelines' UserSettings base class, JsonUserSettingsService, and
IWindowStateStorage. Core's IUserSettingsService is now a lean interface exposing
only app-specific properties (PreferredCulture, SkipLanguageMismatchCheck), while
the Windows project provides AppSettings extending Guidelines' UserSettings and
AppUserSettingsService wrapping JsonUserSettingsService.

 creation

Set LocalizationService.Provider before Host.Start() so it is
available when XAML markup extensions are evaluated during window
and page construction.

Subject: [PATCH 18/34] Replace hardcoded margins and inline styles with shared
 design system tokens

Apply new Guidelines styles (Text.PageMessage, Text.Stat.Label/Value,
Margin.Card, Margin.ContentCenter) across pages. Add ComboBox.Standard
to unstyled ComboBoxes and Card.Standard to inline-styled Cards.

Subject: [PATCH 19/34] Add accessibility properties and fix LedControl
 hardcoded glow color

Replace hardcoded Red DropShadowEffect color with a binding to the LED fill
color so the glow always matches. Add AutomationProperties.Name to DataGrids,
ProgressBar, Image, and Ellipse controls that lacked screen reader context.
Give the expand column a localized header instead of an empty string.

Subject: [PATCH 20/34] Expand ViewModel unit test coverage for trace entry
 processing and supervision

Add 35 new tests covering previously commented-out and missing test areas:
- MonitorViewModel: trace entry statistics, display filtering, line quality,
  buffer management, session lifecycle, and export commands
- ManageViewModel: trace entry activity indicators, supervision tracking
  (tamper, power, online status), and clear supervision history
- ConfigurationViewModel: trace entry activity indicators, USB device
  monitoring with port preservation, and cancel discovery
- Shared TraceEntryTestHelper with valid OSDP packet constants (Poll, ACK,
  NAK, ID Report) using correct CRC-16 checksums

Subject: [PATCH 21/34] Add FlaUI UI testing with Moq service mocking and CI
 pipeline stage

Introduce automated UI testing using FlaUI to verify the WPF application
works end-to-end, with Moq-based service mocking to simulate OSDP device
connections without real hardware. Refactor App.xaml.cs to support
testable service registration via an overridable ConfigureServices method.
Add AutomationId properties to key XAML controls for reliable element
discovery. Add a separate non-blocking UI test stage to the CI pipeline.

Subject: [PATCH 24/34] Add UI test coverage for all pages and replace
 Thread.Sleep with polling

Add 18 new test scenarios across Configuration (advanced), Manage, Monitor,
and Info pages. Replace Thread.Sleep calls with NavigateToPage helpers that
use element polling or dispatcher flush, reducing test runtime by 42%.

Subject: [PATCH 25/34] Fix Configuration page layout overlap and truncation at
 narrow widths

Move ButtonPanel to Grid row 2 in narrow responsive mode to avoid colliding
with the Discover/Manual radio buttons in row 1. Switch connection-mode
radio buttons from StackPanel to WrapPanel so "Passive Mode" text wraps
instead of being clipped. Add UI guideline about Grid row collisions.

 - **Update existing code** - When modifying files, replace inline styling with standard styles
 - **Create reusable patterns** - If you find yourself repeating XAML structures, consider adding a new style or template
 - **Use WrapPanel for responsive layouts** - When controls should be horizontal on wide screens but wrap to vertical on narrow screens, use WrapPanel instead of fixed Grid layouts
+- **Avoid Grid row collisions in responsive layouts** - When using code-behind `SizeChanged` handlers to reposition elements between Grid rows, ensure moved elements don't share a row with existing static content. Always verify that the target row is either empty or the static content is also relocated
 - **Prefer dynamic resources for colors** - Use `{DynamicResource}` instead of `{StaticResource}` for colors to ensure theme compatibility

Subject: [PATCH 26/34] Fix UI flow issues across Monitor, Info, and Manage
 pages

MonitorPage: Use WrapPanel for buffer status row so text and progress bar
wrap at narrow widths; add TextWrapping to trace details TextBox.
InfoPage: Use WrapPanel for language selection to prevent overflow.
ManagePage: Use WrapPanel for vendor info display; replace hardcoded
pixel margins with design token references.

Subject: [PATCH 27/34] Improve Configuration page UX with key field controls,
 placeholders, and layout fixes

Disable passive mode security key when default key is checked, add empty serial
ports warning message, add placeholder text to security key fields, align
UpdateSourceTrigger on both key fields, replace empty label spacer with proper
alignment, and add MinWidth to action buttons for layout stability.

Subject: [PATCH 29/34] Add full buzzer control settings with device capability
 checking

Replace hardcoded "Three Quick Beeps" buzzer action with configurable parameters
(tone code, reader number, on/off time, count) and add capability checking that
disables actions when the device doesn't support the required capability.

Subject: [PATCH 30/34] Add full LED control settings with temp/perm tabs and
 color swatches

Expose all 13 ReaderLedControl parameters via a TabControl with Temporary
and Permanent tabs, replacing the single color dropdown. Color ComboBoxes
show colored squares next to plain English labels matching ACUConsole.

Subject: [PATCH 31/34] Add security key validation highlighting and fix
 passive mode key editing

Real-time visual feedback (red border + red character count) when the
security key is invalid, with Connect/Start buttons disabled until valid.
Fix bug where passive mode UseDefaultKey checkbox couldn't be unchecked
because the guard immediately re-checked it when the key was empty.

Subject: [PATCH 33/34] Add timing validation to buzzer and LED controls with
 mode-aware rules

Buzzer ON time must be non-zero unless tone code is Off. LED timing
validation only applies when the mode actively sets a state (not NOP).
Validation uses SemanticErrorBrush styling and disables the Send button.

Subject: [PATCH 34/34] Add validation error indicators, INotifyPropertyChanged
 fix, and UI tests

Fix buzzer and LED controls not updating validation UI by implementing
INotifyPropertyChanged interface. Wrap NumberBox controls in Border
elements for error highlighting since NumberBox ignores direct style
setters. Add validation error text messages and UI tests for all
validation behavior.
