openai/gpt-chat-latest → B (4:1)

Side B implements a substantial new capability: an asynchronous Reddit import pipeline with a background worker, request deduplication, OAuth support, rate-limit handling, JSON parsing into entity data, integration into application state and page loading, plus tests for URL mapping and parsing. Side A improves pair-selection heuristics with better bridge prioritization and rank-based refinement ordering backed by tests, but it is a targeted algorithm refinement rather than a broad new feature.
