+Output this markdown directly (not as a code block). Route based on UAT results:
+
+| Status | Route |
+|--------|-------|
+| All tests pass + more phases | Route A (next phase) |
+| All tests pass + last phase | Route B (milestone complete) |
+| Issues found + fix plans ready | Route C (execute fixes) |
+| Issues found + planning blocked | Route D (manual intervention) |
