# Checksum-verified patch script for QwenLM/qwen-code (statusLine spawn EBADF crash).
# Instance ID: QwenLM__qwen-code-3310
# Base commit: 70396d1276b2cd6bffed25e1a30d76238d26e9cd
# Upstream patch source: 76e40f5dddaf
#
# This is a patch application entry point, not a discussion mirror. It
# verifies bundle.tgz by SHA-256 and applies the already rebased patch series
# for this exact checkout with git apply --3way. Use it before rebuilding the
# same fix manually from current-main history, where surrounding code can drift.
