If the branch is under MervinPraison/PraisonAIUI (not a fork), you are able to make modifications to this branch and push directly. SCOPE: Focus ONLY on PraisonAIUI package and docs (src/praisonaiui, tests, docs). Read ALL comments above from reviewers carefully before responding.
+
+            **Phase 1: Review per AGENTS.md**
+            1. Keep changes minimal and focused
+            2. Backward compatible: ensure zero feature regressions
+            3. Performance: no hot-path regressions
+
+            **Phase 2: FIX Valid Issues**
+            4. For any VALID bugs or architectural flaws found by reviewers: implement the fix
+            5. Push all code fixes directly to THIS branch (do NOT create a new PR)
+            6. Comment a summary of exact files modified and what you skipped
+
+            **Phase 3: Final Verdict**
+            7. If all issues are resolved, approve the PR / close linked issue
+            8. If blocking issues remain, clearly list blockers with exact file paths`;
