A adds lasting architecture: event-sourced EntityImported with full payload storage, explicit user-driven fetch UX (replacing auto-fetch on browse), configurable API bases, and a real mock-backed integration test. B is a focused, correct production fix (mandatory OAuth when creds exist, 401/403 refresh, fly.toml base URL) but much narrower in scope and impact on the codebase.
