openai/gpt-chat-latest → B (6:1)

Side B implements substantial new functionality: it replaces automatic Reddit fetching with explicit user-triggered fetches, persists full imported API payloads via a new EntityImported event for replay, refactors the reducer to store raw payloads plus derived views, adds configurable API/OAuth bases and dotenv loading, and includes tests and fixtures validating the behavior. Side A is a small but useful bug fix that defines GITHUB_API_BASE_URL with a default to prevent a NameError, but its scope and lasting architectural impact are much narrower.
