 ## [Unreleased]
 
+### Added
+
+- 🧾 **Transcription policy check.** `Test-LoggingBaseline.ps1` now has a read-only Safety row for the PowerShell transcription policy, which the kit never sets. On with no `OutputDirectory` fails, because every session then writes a transcript into the user's Documents folder; on with a folder passes with a note; off passes. Machine policy takes precedence; the user policy of the account running the test is read when no machine policy is set, and a `Wow6432Node` copy that disagrees is noted. The Safety never-do table explains it. [#91](https://github.com/spydisec/WinLogKit/issues/91)
+
 ## [2.2.2] - 2026-09-24
 
 Documentation only: one checklist for fitting the kit to your own infrastructure before rolling it out. No script or setting changes; nothing to do when upgrading from 2.2.1.

If another policy turns it on **without an `OutputDirectory`** (machine policy, or the user policy of the account running the test when no machine policy is set), every Windows PowerShell session writes a transcript into the user's Documents folder, which Microsoft documents as the policy's default behaviour ([Policy CSP](https://learn.microsoft.com/windows/client-management/mdm/policy-csp-admx-powershellexecutionpolicy#enabletranscripting)). The test **fails** that state and passes transcription that is directed to a folder. If you want transcripts, set them by GPO to a central folder readable only by the people who need them. |
