From 0e9de14d4648e2a503849ed7f8f046667b686045 Mon Sep 17 00:00:00 2001 From: Julian lechner Date: Fri, 11 Sep 2026 15:43:21 +0200 Subject: [PATCH] test: add managed-manifest installer scenarios (PowerShell) Exercises Sync-ManagedDestination directly against a throwaway source/destination pair: idempotent second install (no writes, no backups), removal of a stale-and-untouched file, protection of a stale-but-locally-modified file (backed up, left in place, warned), a foreign file that was never installed staying untouched, and a dry run that reports the planned removal without any side effects.
