~x-ai/grok-latest → A (8:1)

Side A seeds the project's core lasting systems (rank-centrality with #146 regression tests and connected components in ranking.rs, full event-sourced ReducerState/GroupState in reducer.rs, the graph-based Reddit URL parser with extensive keystroke-flow tests, form $form template fill, HtmlUiAction, and the complete vote-compare page/UI), whereas Side B only adds a single clean but narrower Reddit HTTP client with rate limits and serde types. A's volume includes some pasted shell noise and note files, but the real algorithms, state machine, and UI plumbing dominate lasting value over B's useful-but-peripheral fetch layer.
