--dist=loadscope is a no-op with -n 1

For the llms-vertex group (workers: 1), --dist=loadscope has no effect since there's only one worker — there's nothing to distribute. This is harmless, but you could consider conditionally applying it only when workers > 1 for clarity, or just leave it as-is for simplicity since the overhead is negligible.

Note: If this suggestion doesn't match your team's coding style, reply to this and let me know. I'll remember it for next time!
