The Windows workflow targets disposable Server 2022/2025 runners under both WELA hosts (5.1 and 7). Its explicitly gated native test creates only owned private directories, saves original policy, configures transcription, launches fresh native Windows PowerShell 5.1 sessions (native/x86 where installed), and searches for benign markers in automatically produced transcript files. It restores exact original policy in `finally`, verifies restoration, and removes its generated files. If restoration fails, it fails the job and retains the private recovery evidence. PowerShell 7 is a test host, not a transcript-generation target. -Windows-native CI must pass before claiming that evidence for this change. Production/central validation still requires actual client, server, DC and service identities: test a benign new session, record the transcript and effective policy, verify unauthorized read/modify attempts fail, check collection and quotas/retention, and verify recovery.
