openai/gpt-5.2-chat → A (5:1)

Side A is effectively a foundational project seed: it introduces large core modules (parser ~1800 LOC, reducer ~800+ LOC, ranking ~400 LOC, vote UI, form handling, UI actions), extensive tests, scripts, and multiple new subsystems. It establishes the primary application architecture. Side B is a substantial and sophisticated feature addition (multi-repository git discovery, emission integration, and extensive tests), but it builds within an existing system and is narrower in scope. In terms of total code volume, architectural surface area, and baseline functionality introduced, Side A contributes significantly more.
