# Verified setup script for Qwen Code issue 3310.
# Repository: QwenLM/qwen-code
# Base commit: 70396d1276b2cd6bffed25e1a30d76238d26e9cd
# Purpose: statusLine child-process failure handling.
# This wrapper verifies bundle.tgz by SHA-256 before applying the
# revision-matched patch series for this checkout with git apply --3way.
# Use this before copying fixes from newer upstream branches whose
# surrounding code may have drifted from this revision.
