openai/gpt-5.2-chat → B (9:1)

Side B introduces a substantial new extensible URL foundation and GitHub external resolver system: new resolver module with API integration, cooldown logic, system ingest pathway, write command, UI actions, garden UI controls, normalization changes, extensive tests (unit + browser), and state wiring. This meaningfully expands platform capabilities. Side A mainly fixes vote compare highlighting and slider polarity with related CSS/JS tweaks and tests—valuable but comparatively incremental. Therefore B contributes far more overall functionality and architectural impact.
