openai/gpt-chat-latest → B (3:2)

Side B makes a concrete functional improvement by replacing the global `#entity-section` target with per-item `data-entity-section` selectors, allowing SSE/Idiomorph updates to address the correct entity block, and it reuses the shared `entity_section` rendering in the voting UI instead of duplicating markup. Side A is primarily a large architectural refactor of the URL canonicalization layer (replacing `engine` with `graph`/`parse` and updating the API), but the shown patch mostly removes code and redirects to new modules whose implementation is not included, making its lasting functional benefit less directly demonstrated by the diff.
