B is a small, precise, correct bugfix (moving the zero-ratio guard before side effects) with a clear regression test proving the fix, directly preventing ghost items and incorrect voted_pairs state. A is a much larger feature addition (entity import/fetch UI, dotenv, reddit API refactor) that adds real value but is diffuse, includes a stray unrelated Clojure integration test file, and carries more risk/noise without the same tight correctness guarantee.

council reasoning
A redesigns Reddit/entity import into an event-sourced pipeline (EntityImported + raw payload storage, explicit fetch UI, no auto-fetch on browse, configurable API bases, fixtures and end-to-end test), which is lasting product and architecture value. B is a real but narrow correctness fix—moving the zero-ratio early-return before ensure_item/voted_pairs—so it stops ghost items and bad pair state without comparable scope.
Side A implements a substantial architectural improvement: it replaces implicit Reddit fetches with explicit user-triggered imports, persists full upstream payloads via a new EntityImported event, replays them into state, adds configurable API/OAuth endpoints and dotenv loading, and includes integration/tests around the new behavior. Side B fixes a real reducer bug by moving the zero-ratio guard ahead of item/pair registration to prevent ghost entries and incorrect voted_pairs state, but it is a narrowly scoped correctness fix compared with A's broader lasting functionality.

[81de487b] Fix zero-ratio guard in reducer to drop before registering items or pair. Previously the early-return for zero-weight votes happened after ensure_item and voted_pairs.insert, leaving ghost items in the index and the pair incorrectly marked as voted. Move the check to before any side effects. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
