openai/gpt-5.2-chat → A (8:1)

Side A introduces a substantial new feature set: extensible URL normalization (including GitHub and YouTube handling), an on-demand GitHub external resolver with API integration, system-level ingest plumbing, UI controls, cooldown state, DSL/test updates, and new browser coverage. It touches many core modules (state, writer actor, HTML, URL identity, external resolver, tests) and adds meaningful new capabilities. Side B is a focused improvement to vote pool href encoding plus a stronger end-to-end test asserting full ranking behavior. While valuable, it is comparatively small in scope and architectural impact.
