+"""Regression: Windows installer must not gut the venv on rename failure (#83149).
+
+When recreating an existing venv, ``Install-Venv`` renames the directory aside
+first. An older fallback deleted the tree in place when rename was denied; a
+partial ``Remove-Item`` could wipe most of ``site-packages`` and then fail on
+one locked ``.pyd``, leaving Hermes unusable with no rollback.
+
+These tests lock the contract at the source level (the script only runs on
+Windows, so Linux CI cannot execute the PowerShell path).
