openai/gpt-chat-latest → A (3:2)

Side A introduces a new workspace tool (`sorterc`) plus reusable `server::offline` APIs to compile `.sorter` files, replay `events.jsonl`, detect malformed ingests, and validate reducer state offline, with CLI integration, documentation, and tests. Side B improves Reddit presentation by adding richer entity rendering, thumbnails, image/link extraction, and supporting tests/CSS, but it is primarily a UI enhancement whereas Side A adds broader development and validation infrastructure that is likely to benefit ongoing maintenance and correctness.
