+# Properties
+
+### Purpose
+This module provides assembly-level metadata and application/user settings configuration for the DatabaseImport assembly. It defines persistent configuration values including download paths, auto-arm permissions, calibration warning periods, database type selection, and ISO export compatibility requirements.
+
+### Public Interface
+
+**`Settings` (sealed partial class, internal)**
+- `public static Settings Default { get; }` — Singleton instance accessor returning synchronized settings.
+- `public string DownloadFolder { get; }` — Application-scoped setting, default value `"..\\Data"`.
+- `public bool AllowAutoArm { get; }` — Application-scoped setting, default value `false`.
+- `public int CalWarningPeriodDays { get; set; }` — User-scoped setting, default value `7`.
+- `public int DBType { get; }` — Application-scoped setting, default value `1`.
+- `public bool RequireXCrashCompatibilityForISOExports { get; }` — Application-scoped setting, default value `true`.
+
+### Invariants
+- `Settings` inherits from `System.Configuration.ApplicationSettingsBase` and uses thread synchronization via `Synchronized()`.
+- Application-scoped settings (`DownloadFolder`, `AllowAutoArm`, `DBType`, `RequireXCrashCompatibilityForISOExports`) are read-only at runtime.
+- User-scoped settings (`CalWarningPeriodDays`) can be modified and persisted.
+- The class is auto-generated by `SettingsSingleFileGenerator`; manual changes will be overwritten.
+
+### Dependencies
+- **Depends on**: `System.Configuration.ApplicationSettingsBase`, `System.Runtime.CompilerServices`, `System.CodeDom.Compiler`.
+- **Depended on by**: Unclear from source alone; likely consumed throughout the DatabaseImport assembly for configuration access.
+
+### Gotchas
+- `DownloadFolder` uses a relative path `"..\\Data"`; the actual location depends on the working directory at runtime.
+- `DBType` is an integer (default `1`); the mapping of integer values to database types is not defined in this source.
+- The `CalWarningPeriodDays` is user-scoped, meaning it can vary per user profile; other settings are application-wide.
