Commit B is a substantial, coherent feature/refactor: it introduces explicit user-triggered entity fetching, persists full raw API payloads via a new EntityImported event for proper replay, decouples Reddit API base URLs for testability, adds dotenv support, and includes a real integration test with a mock Reddit server plus fixture data. Commit A is a small, well-tested but narrow bugfix (skipping pinned posts) that adds real value but is far more limited in scope and lasting architectural impact compared to B's persistence/import redesign.

council reasoning
B redesigns Reddit import around event-sourced EntityImported payloads, explicit user fetch (no auto-fetch on browse), configurable API bases, raw+view storage, and end-to-end tests—foundational lasting architecture. A only adds a small stickied/pinned skip in parse_children plus one unit test, a correct but narrow data-quality tweak.
Side B introduces substantial new architecture: it replaces ephemeral Reddit entity updates with persisted `EntityImported` events, stores raw API payloads plus derived views, adds replay support, configurable API/OAuth endpoints, and an explicit user-triggered fetch flow with tests. Side A is a focused correctness fix that skips stickied/pinned subreddit posts during import and adds a targeted regression test, but its scope and long-term impact are much smaller than the persistence and fetch redesign in Side B.
