~anthropic/claude-sonnet-latest → B (3:2)

Side B fixes an actual production bug (mislabeled unranked child titles and incorrect import wiring that bypassed ensure_path for Reddit children), with corresponding updates to integration tests validating the fix. Side A adds a new dev-only tool that is useful but non-critical infrastructure; it's larger in volume but doesn't fix any existing defect, whereas B delivers a real correctness improvement to shipped behavior.
