claude-code - 💡(How to fix) Fix [Bug] NameError in orchestrator error handler crashes Bug Hunter review on agent failure

Bug Description Ran /code-review ultra 936 against PR stratis-technology/stratOS#936. The remote Bug Hunter review authenticated and started, then crashed after ~24s with 0 findings — and the root cause is in the orchestrator's own error handler, not the reviewed PR. A worker-agent subprocess exited 1, and the handler then threw:

NameError: name 'stderr_lines' is not defined. Did you mean: 'stderr_file'? at bughunter/orchestrator.py:4536

That undefined-variable bug turned a recoverable agent failure into a fatal crash, aborting the whole run (all 5 agents cancelled, exit 1).

It counted as "Free ultrareview 1 of 3" despite delivering nothing — requesting that credit be refunded. Cloud session: session_01VAa8bsC2U3rehymxdqGybw.
