Side B delivers a substantive architectural change (offloading Reddit JSON payloads to a RocksDB-backed entity store, streaming event log replay to cut startup RAM) with tests validating persistence and replay correctness, despite noisy vendored Cargo.lock churn. Side A mostly removes a demo feature and adds a settlement worker/cache that duplicates ranking logic without clear necessity, offering less lasting architectural value relative to its complexity.
