Side A replaces a Reddit placeholder with a functional background import system: it adds a broker/worker, OAuth support, rate-limit handling, request deduplication, JSON parsing into EntityData, automatic fetch triggering from page views and item creation, plus tests for URL mapping and parsing. Side B contains worthwhile architectural cleanup by removing demo code and introducing a settlement worker with cached ranking computation, but much of the patch is refactoring and performance-oriented, whereas Side A delivers a substantial new capability that is likely to provide more lasting project value.
