+
+The automated test cases use Pester 5 and do not modify the registry or other
+system state. The optional bootstrap step installs Pester for your user account
+when needed. To run the complete suite:
+
+```powershell
+.\Scripts\Run-Tests.ps1 -Bootstrap
+```
+
+After the initial setup, run the suite with:
+
+```powershell
+.\Scripts\Run-Tests.ps1

+GitHub Actions runs the same test command with Windows PowerShell 5.1 for pull
+requests and pushes to `master`.

 #### 1b. Implement the Feature Logic

-If your feature requires more than just applying a registry file, add custom logic to the main script in the appropriate section. In most cases this will involve creating a new entry in the `Invoke-FeatureApply` function (in `Scripts/Features/InvokeChanges.ps1`) for your new feature. If your feature also requires custom undo logic (beyond a simple registry file import), add a corresponding entry to the `Invoke-FeatureUndo` function in the same file.

+        Undoes a single feature.

    .DESCRIPTION
-        Handles undo for features that require custom logic rather than a simple
-        .reg file import. Features with a RegistryUndoKey are handled directly
-        via ImportRegistryFile in Invoke-UndoFeatures.
+        Handles registry-backed undo imports and custom undo logic. Returns
+        $true when the requested undo succeeds; otherwise writes a warning and
+        returns $false.

+<#
+    .SYNOPSIS
+        Resolve a user name to a full profile context (name, SID, path).
+
+    .DESCRIPTION
+        SID-keyed registry data first (authoritative), then on-disk path
+        probing so resolution still succeeds when the account or SID can't be
+        looked up (deleted account, restricted context). Returns $null if not
+        found.
+
+    .PARAMETER UserName
+        User name whose profile context is required.
+
+    .OUTPUTS
