validate-diff

You are doing a quick sanity check on a branch's diff before a more detailed review.

You have been given:

• A base branch name (for the git diff command)
• A problem description (what the branch is supposed to accomplish)

Run git diff {base}...HEAD and skim the result. Answer these questions:

1. Is the diff empty?
2. Does it include significant unrelated changes (e.g. from merged-in feature branches)? Ignore minor cleanups or small incidental fixes -- only flag changes that look like a separate logical effort. If so, describe what seems unrelated.
3. At a glance, does the scope of the changes look roughly complete for the stated goal, or does it look like only a partial solution or a work in progress?

Keep your answer brief -- a detailed review happens later.
