~x-ai/grok-latest → B (2:3)

B fixes lasting import/tree behavior: Reddit children attach via apply_entity_under_parent (no ensure_path intermediate segments) and ranking_panel shows real titles through child_label, with call sites and import tests updated. A’s production change is a narrower href encoding fix (display_path in vote links) plus a stronger 45-pair ranking browser test—valuable verification, but less core product impact than B’s data/UI wiring fix.
