+# Documentation: DockPanelHorizontalView
+
+## 1. Purpose
+
+`DockPanelHorizontalView` is a WPF view component representing a horizontal dock panel within the DTS Viewer application. It serves as a UI container for horizontally-arranged docked elements, implementing the `IDockPanelHorizontalView` interface to integrate with the broader docking system architecture. This module exists to provide the code-behind logic for the corresponding XAML view definition.
+
+## 2. Public Interface
+
+### Class: `DockPanelHorizontalView`
+
+**Kind:** `partial class`  
+**Implements:** `IDockPanelHorizontalView`  
+**Namespace:** `DTS.Viewer`
+
+#### Constructor
+
+```csharp
+public DockPanelHorizontalView()
+```
+
+Initializes a new instance of the `DockPanelHorizontalView` class. Invokes `InitializeComponent()`, which loads and instantiates the XAML-defined UI component tree.
+
+---
+
+## 3. Invariants
+
+- The class is declared as `partial`, indicating that additional implementation is auto-generated from the companion XAML file (`DockPanelHorizontalView.xaml`) at build time.
+- `InitializeComponent()` must be called exactly once during construction; this is enforced by WPF's code-generation pattern.
+- The class implements `IDockPanelHorizontalView`, implying it must fulfill any contract defined by that interface (interface members are not visible in this source file).
+
+## 4. Dependencies
+
+### This module depends on:
+- `DTS.Common.Base` — imported but no specific types are referenced in this file; usage unclear from source alone
+- `DTS.Common.Interface` — provides `IDockPanelHorizontalView` interface
+- WPF Presentation Framework (implicit via `InitializeComponent()` pattern)
+
+### What depends on this module:
+- Cannot be determined from this source file alone. Likely consumed by a parent container or DI container within the `DTS.Viewer` assembly.
+
+## 5. Gotchas
+
+- The actual UI layout, visual tree, and any named elements are defined in the companion XAML file (`DockPanelHorizontalView.xaml`), which is not included here. The behavior and structure of this view cannot be fully understood without that file.
+- The `IDockPanelHorizontalView` interface contract is not visible in this source; any required interface members (properties, methods, events) are not shown.
+- The import of `DTS.Common.Base` is unused in this file—this may indicate dead code, a historical remnant, or types used in the XAML portion.
