Slice 22.1 – Setup-integrated FLUX recovery

Confirmed incident

The 7-Zip process completed successfully with Everything is Ok, 54,878 files and about 4,038 MB extracted. Windows PowerShell 5.1 nevertheless exposed an empty Process.ExitCode, which the previous installer treated as a non-zero failure.

Recovery contract

The setup startup recovery activates only when all of these conditions match:

1. install-state.json is failed and can_resume=true.
2. The stored message contains the empty 7-Zip exit-code failure and Everything is Ok.
3. The 7-Zip stderr log is empty.
4. The stdout log contains the success marker.
5. The extracted portable tree contains both ComfyUI\main.py and python_embeded\python.exe.
6. No matching installer or 7-Zip process is still active.
7. The final ComfyUI target is not already installed.

The user starts only setup.bat. Setup then offers to continue automatically. The complete extraction is reused; no repeat extraction or project reset occurs.
