Central pin 1.1.0 -> 3.2.2; AdminUI/ControlPlane/Runtime/Host.Tests no longer carry VersionOverride.
The three driver IntegrationTests fixtures' Fact/Theory attributes gain the source-info ctor (xUnit3003).
No xUnit1051 fallout remained (already cleaned). Test counts unchanged.

Akka.TestKit.Xunit2 -> Akka.TestKit.Xunit 1.5.62 (xunit.v3 TestKit; needs xunit.v3 3.2.2, set via
VersionOverride on the four projects). Removes the xunit 2.9.3 pin. IAsyncLifetime returns ValueTask,
SqlServerFactAttribute gains the source-info ctor, and xUnit1051 call sites pass
TestContext.Current.CancellationToken. Test counts unchanged.

Owner decisions §14 #5/#6 as built (design §12.5):
- Scripting:Worker:Identity (default unset, Windows only, fail-closed validation): each worker
starts under a restricted token derived from the host's. Every privilege but SeChangeNotify is
removed; the restricting SIDs are NT SERVICE\OtOpcUaScriptWorker's SID + Everyone + Users +
RESTRICTED; the token and default DACLs are host + SYSTEM + identity + RESTRICTED. The worker
is created suspended, put in its Job Object before it runs, inherits only its stdio pipes, gets
an ACL'd work dir as TEMP, and runs with DOTNET_EnableDiagnostics=0. The identity is granted on
the host's window station and desktop, because USER32 init made coreclr.dll fail with
ERROR_DLL_INIT_FAILED on windev. The logon SID is not used because the host's process DACL
gives it PROCESS_VM_READ.
- The worker pipe on Windows always has an explicit protected DACL: host account + identity
only. There is no owner ACE, so an elevated host's Administrators gets no access.
- The worker treats access denied on its parent-pid poll as alive; the Job Object covers that case.
- scripts/install/Install-ScriptWorkerIsolation.ps1 + ScriptWorkerIsolation.psm1 are idempotent
and support -WhatIf, -Uninstall and -PlanOnly. They create the disabled anchor service, the
PeCacheDir ACL (protected, no Users, key and markers host-only, pe\ Modify for the identity),
read+execute on script-worker\, a ReadData deny on the install root, the outbound firewall
block on the worker exe, and optionally the host-service env.
- Tests: the dry-run harness scripts/install/tests/Test-ScriptWorkerIsolation.ps1 (46
assertions, mutation-checked); ScriptWorkerIdentityTests; WorkerIsolationTests, which cover
the pipe ACL, token access and a real restricted worker running a script, all green on windev.

ForbiddenTypeAnalyzer now denies System.AppContext, System.Console, GCSettings, ProfileOptimization,
EncodingProvider/CodePagesEncodingProvider, TypeDescriptor and CryptoConfig as types, and the ambient
CultureInfo.{DefaultThreadCurrentCulture,DefaultThreadCurrentUICulture,CurrentCulture,CurrentUICulture}
and TimeZoneInfo.ClearCachedData members (member deny-list now covers properties and member-access reads).
Shadow-mode tests diverge via culture-sensitive string.Compare (worker is InvariantGlobalization) instead of
AppContext.BaseDirectory, with a premise test. Mutation-proved: 21 new cases fail with the analyzer reverted.
