研究方向
Start by examining the linked PR #168 to understand the SOURCE BRANCH environment variable and how it was used there. Then, locate the Dockerfile in the repository (likely at ./Dockerfile or similar) and identify where the build context is set. The change likely involves adding an `ARG` or `ENV` line to pass the branch name from the build environment. Test the change locally using Docker build with the variable set.
