Side B implements a substantive feature (explicit user-triggered Reddit entity fetch, event-sourced raw payload storage, replay support, config injection for testability, and an integration test with a mock server), representing real architectural and functional progress. Side A is a small correctness cleanup (replacing a silent default with an explicit expect and dropping a conditional link check) plus doc-comment fixes, useful but far more limited in scope and lasting impact.
