~x-ai/grok-latest → B (2:1)

B replaces an unreliable ~1.8k-line keystroke graph, parser_action types, race-prone JS, and Playwright race test with a small paste-and-go URL parser and redirect—lasting maintainability by deleting brittle subsystem code. A is a real, precise bugfix (apply_entity_under_parent vs ensure_path/link_child, title-based unranked labels, stronger import tests) but narrower in scope than removing the failed autocomplete architecture.
