## Documentation: TTSImport Module (Assembly)

### 1. Purpose  
This module (`TTSImport`) is an assembly responsible for handling test setup import functionality—specifically for TTS (presumably *Test Template System* or a domain-specific acronym)—within the DataPRO platform. It provides configuration storage for user-scoped settings (e.g., default import method) and is structured as a .NET class library with standard assembly metadata (title, version, COM visibility control). Its role is foundational: it enables consistent configuration management for downstream import logic (not included in these files), likely consumed by other modules in the `DataPRO.Modules.TestSetups.Imports.TTS` namespace.

### 2. Public Interface  
The module exposes only one public type:  

- **`TTSImport.Properties.Settings`**  
  - *Type*: `internal sealed partial class` inheriting from `System.Configuration.ApplicationSettingsBase`.  
  - *Access*: Accessed via the static property `Settings.Default`.  
  - *Behavior*: Provides user-scoped application settings. Currently defines one setting:  
    - `int DefaultTestImportMethod { get; set; }`  
      - Default value: `"0"` (as specified by `DefaultSettingValueAttribute`).  
      - Marked with `UserScopedSettingAttribute`, meaning it persists per-user (e.g., in user.config).  
      - Notable: The class is `internal`, so it is only accessible within the same assembly. External consumers would need to reference the assembly and access it via reflection or if exposed by another public type (not present here).

### 3. Invariants  
- The `Settings.Default` instance is lazily initialized and synchronized via `ApplicationSettingsBase.Synchronized`, ensuring thread-safe access to the default instance.  
- The `DefaultTestImportMethod` value is guaranteed to be an `int` (no validation beyond type safety); its semantics (e.g., what values are valid) are not defined in this file.  
- Assembly version is fixed at `1.0.0.0` (both `AssemblyVersion` and `AssemblyFileVersion`).  
- `ComVisible(false)` ensures no types in this assembly are exposed to COM by default.

### 4. Dependencies  
- **Dependencies *of* this module**:  
  - `System.Configuration` (for `ApplicationSettingsBase`, `UserScopedSettingAttribute`, etc.)  
  - `System.Runtime.CompilerServices`, `System.Runtime.InteropServices`, `System.Diagnostics` (for attributes)  
- **Dependencies *on* this module**:  
  - Not inferable from these files alone. However, given the path `DataPRO/Modules/TestSetups/Imports/TTS/`, it is likely consumed by other modules in the `DataPRO.Modules.TestSetups.Imports` hierarchy (e.g., a main TTS import handler).  
  - The `Guid` (`a8ff540f-f22a-45ae-a63b-4984ed74c654`) suggests potential COM interop usage, though `ComVisible(false)` disables it.

### 5. Gotchas  
- The `Settings` class is `internal`, so external assemblies cannot directly reference `Settings.Default` without reflection or an additional public wrapper.  
- The `DefaultTestImportMethod` setting has no documented valid range or semantic meaning (e.g., is `0` a "manual" mode? `1` "auto"?). This must be determined from consuming code or external documentation.  
- Auto-generated comment in `Settings.Designer.cs` warns that manual changes will be lost on regeneration—likely triggered by Visual Studio’s settings designer.  
- `AssemblyVersion("1.0.0.0")` with `AssemblyFileVersion("1.0.0.0")` suggests this is an initial release; no versioning strategy is evident here.  
- No public API surface beyond `Settings.Default`; the module’s primary functionality (test import logic) resides elsewhere.
