Side B repairs broken OAuth test infrastructure by fixing query parsing (`str/split` regex), reading POST bodies from `getRequestBody`, handling missing state/token values safely, correcting redirect responses, and wrapping mock handlers to avoid crashes, directly restoring end-to-end authentication flows. Side A adds useful UI enhancements (pairwise vote counts, HUD unpin button, styling, and tests), but these are primarily feature and UX improvements rather than restoring critical project functionality.
