+The rebuilt compact installer passes six isolated Windows PowerShell 5
+fixtures (`quick-fixtures-final/summary.json`): exact backup/restore with the
+original game DLSS DLL preserved, automatic gfx1201 selection, a child that
+refuses debugging with empty stderr, and four negative input/package gates.
+The child exits normally with no debugger and is classified as inconclusive,
+with hardwareValidationCompleted=false. No installed game is changed by the
+fixtures. Run `test-windows-quick-test.ps1` with the package and the local DLL
+paths to reproduce them; it selects Windows PowerShell 5 when called from 7.
+The follow-up compact release is `windows-quick-test-20261002-issue10` in the
+fork, with all eleven targets and a separate exact GPL corresponding-source
+asset. Native network arithmetic and conservative scheduling are unchanged.
+
 These tests do not validate the reporter's gfx1200 kernels or game image.
 The local Cyberpunk EXE is `D:\Games\Cyberpunk 2077\bin\x64\Cyberpunk2077.exe`;
 it is located but is not launched or modified while the user is away.
