openai/gpt-5.2-chat → A (5:1)

Side A introduces a substantial new extensible URL and external resolution foundation: it adds a GitHubResolver with API integration, cooldown tracking in AppState, a new SystemIngest write path, DSL support for fenced JSON bodies, URL normalization changes, UI controls, and end-to-end browser tests. Side B is a focused improvement to vote_compare_href/vote_pool_href to use display_path plus a stronger browser test asserting all 45 pairwise votes and final ranking, which is valuable but much narrower in scope and architectural impact.
