+- Solve the user’s request end‑to‑end before yielding.
+- Prefer root‑cause fixes over surface patches.

+- Avoid fixing unrelated issues; mention them briefly if relevant.
+- After changes, run focused validation; expand scope only as needed.
+- Summarize results clearly with next actions or options.
