~anthropic/claude-sonnet-latest → B (6:4)

Side B fixes an actual data-modeling bug (Reddit children incorrectly running ensure_path and losing entity_view wiring), threads the tree context through ranking_panel so unranked child labels display correctly, and updates/extends integration tests to verify the fix. Side A is mostly config/env plumbing (extracting a get-base-url helper and changing deploy branch), which is useful but lower-impact and more mechanical than B's genuine bugfix with test coverage.
