openai/gpt-chat-latest → A (3:2)

Side A introduces substantial new functionality and architectural improvements: it replaces automatic Reddit fetching with explicit user-triggered imports, persists full upstream payloads as replayable EntityImported events, stores raw entity data alongside derived views, adds configurable API/OAuth endpoints, dotenv loading, and corresponding integration/tests. Side B meaningfully improves the vote-pair selection heuristic by prioritizing component attachment and adjacent-rank refinement with good test coverage, but its impact is limited to algorithmic scheduling within an existing feature rather than adding durable infrastructure and persistence capabilities.
