 .PARAMETER SshKeyPath
     SSH private key for the ci_build user in the guest. Default: F:\CI\keys\ci_linux
 
+.PARAMETER UseGitClone
+    If set, skips host-side git clone and delegates cloning to the guest VM.
+    Uses -GuestRepoUrl (HTTP) instead of the SSH alias URL.
+    Mirrors the -UseGitClone mode of Invoke-CIJob.ps1 (same as §3.3 for Windows).
+
+.PARAMETER GuestRepoUrl
+    HTTP(S) URL used for in-VM clone when -UseGitClone is set.
+    Must be reachable from inside the Linux guest VM.
+    Default: https://gitea.emulab.it/Simone/nsis-plugin-ns7zip.git
+
 .PARAMETER VerifyArtifact
     If set, expands artifacts.zip (or scans the dir) and checks that at least one DLL is present.
     Default: $true
