v2-ci / unit-tests (push) Waiting to run
The installer denied NT SERVICE\OtOpcUaScriptWorker only on -InstallRoot. On the wonder layout the node's keys and secrets sit beside it (E:\ApiInstall\OtOpcUa\pki with the application certificate's private key, data\ with secrets.db and LocalDb), inheriting BUILTIN\Users:RX. Users is a restricting SID of the worker token, so a worker could read them. - Install-ScriptWorkerIsolation.ps1 -DenyPaths <dir>,...: each folder gets the same inherited deny as InstallRoot (new SensitiveDirDeny steps). Refuses drive/share roots, script-worker\ and the PE cache; folders must exist; a comma/semicolon string works for powershell -File. - The deny is read AND write (0xD0157: ReadData, WriteData, AppendData, WriteEA, DeleteChild, WriteAttributes, Delete, WRITE_DAC, WRITE_OWNER). Traverse/Execute, ReadAttributes, ReadControl and Synchronize stay so the loader still reaches script-worker\. The write half stops a worker planting a cert in pki\trusted\certs where a data drive lets Users create files in subfolders. - The list is recorded under the anchor service's key (Parameters\DenyPaths, step DenyPathRecord): a re-run removes the deny from folders dropped from the list, -Uninstall removes every recorded one without repeating -DenyPaths. -WhatIf/-PlanOnly print every step. - After an apply, WARN for each protected-DACL item under a denied folder that the inherited deny cannot reach; without -DenyPaths, WARN for pki/data/logs/backup/config/secrets siblings of InstallRoot. Tests: - Dry-run harness 46 -> 86 assertions (QA layout plan, mask bits, refusals, stale removal, record-driven rollback, host account never denied). Mutations (no sibling deny, deny->allow, mask back to ReadData, no stale removal, rollback ignoring the record, script-worker not refused) each turn it red. - Test-ScriptWorkerIsolation.Windows.ps1 (Windows PowerShell 5.1, windev): 34/34, incl. -DenyPaths apply, 11/11 unchanged re-apply, shorter-list re-apply, uninstall from the record, second uninstall unchanged. - New InstallerLayoutIsolationTests (OTOPCUA_ISOLATION_INSTALLER_E2E=1, elevated Windows): a scratch wonder layout under the real restricted worker token. Before install and after uninstall the token reads pki/data/ logs/backup/appsettings and plants a trust-list file; installed it can do neither, still reads script-worker\, a real worker launched from the layout runs a script, and the host still reads everything. Mutating the -DenyPaths denies to a no-op mask turns it red on pki\own\private\otopcua.pfx (reproduces #890). QA vq03/vq04 are NOT re-applied; the command is in docs/deploy/qa-upgrade-b8b4c18f-to-fea7de0a.md. Claude-Session: https://claude.ai/code/session_01GT67ACmpMR7b9LGRPLijMi
