Side B implements a substantial Reddit integration: it adds a background fetch broker with deduplication, rate limiting, OAuth support, JSON parsing into EntityData, automatic fetch triggering from application state and browse requests, and accompanying tests. Side A fixes an important XSS risk by introducing Ammonia-based sanitization before rendering Reddit HTML with tests, but it is a focused security hardening change affecting only rendering, whereas Side B establishes a major lasting subsystem for Reddit data ingestion.
