Side A introduces a durable architectural improvement: it replaces automatic Reddit fetches with an explicit user-triggered fetch flow, persists full imported API payloads as `EntityImported` events for replay, stores raw entity data alongside derived views, adds configurable API endpoints, and includes replay/integration tests. Side B is a solid correctness fix that consistently enforces valid vote ratios (1–100) across the parser, UI handler, reducer, and tests, but its scope is limited to input validation and guarding invalid graph edges.
