The four ConvertTo-SecureString -AsPlainText calls of Probe-EffectiveAccess.ps1
and Run-MatrixLocalSuite.ps1 get a SuppressMessageAttribute with a
justification, as the controller already has for the same case: the lab
installation password comes from the AutomatedLab lab definition and the
passwords of the probe users are random and exist only in memory.
The header of Test-MatrixCleanup.ps1 says that Repair matches the prefixes of
the kit in the whole domain and on the whole machine, which the security review
pointed out, and that an unresolved S-1-5-21-* member of Performance Log Users
can be a real principal of a trust that is down.

The suite runner removes its stage on a machine after it has copied the results
back; after an early stop, the stage stays for the diagnosis. The end-state check
counts the items in the stage folders and the scheduled tasks and standard users
of the kit, and -Mode Repair removes what is left of the stage and the tasks.
Probe-AccountRecreation.ps1 deletes an account and creates it again with the same
name in a loop, logs the user on with Kerberos S4U on the domain controller, the
client, and the file server, and asks Get-NTFSEffectiveAccess of each module under
test. It shows that Windows returns the old SID and groups, whichever version of
the module asks.

The review of the matrix kit found no Blocker or Major issue and these
Minor ones, all fixed here:
- Add-OsMatrixMachine.ps1 assigned the path of the AutomatedLab disk
deployment lock before it checked that the lock exists, so a refusal because
another deployment held the lock made the finally block delete that foreign
lock. The path is kept until this script has created the lock.
- Repair-OsMatrixBoot.ps1 tested the switches of the machine with an array
-ne, which is false for a machine without an adapter, so the guard that is
meant to refuse a machine outside the lab let it through and the script
turned it off. The guard counts the switches now.
- Deploy-OsMatrixLab.ps1 took the installation and domain administrator
password of the lab from Get-Random, which isn't a cryptographic generator.
It uses RandomNumberGenerator without a remainder bias, as the controller
does.
- Run-MatrixLocalSuite.ps1 removed its scheduled tasks, which store the
password of the account that runs them, only after a successful poll. The
finally block of the machine removes the tasks of the run now.
- Probe-EffectiveAccess.ps1 cleaned up the domain controller before the machine
without a try block, so a failure there skipped the cleanup of the machine.

Tests\Lab\Acceptance gets the scripts of Decision 24, which extends the
acceptance of the live tests from one lab to several operating-system builds:
- Deploy-OsMatrixLab.ps1, Add-OsMatrixMachine.ps1, Complete-OsMatrixLab.ps1
and Repair-OsMatrixBoot.ps1 build NtfsSecurityOsMatrixLab with AutomatedLab
(Server 2019, 2022 and 2025 file servers, Windows 11 clients) and repair a
base image whose host-side bcdboot left an empty EFI system partition.
- Test-MatrixReadiness.ps1 and Test-MatrixCleanup.ps1 gate each run and prove
that it left nothing behind (fixture accounts, shares, folders, group
members, orphaned SIDs, profiles); -Mode Repair removes what is left.
- Run-MatrixSequence.ps1 runs the live controller for every cell of the matrix
and stops after an infrastructure failure.
- Run-MatrixLocalSuite.ps1 and Invoke-LocalSuite.ps1 run the module's own
Pester suite on each machine in both editions, elevated and as a basic user,
as scheduled tasks: a process started from a remoting session gets every
privilege enabled, which eight of the tests do not expect.
- Export-MatrixResults.ps1 collates the cells, the skipped tests and the
package hashes into the results table.
