openai/gpt-chat-latest → B (6:1)

Commit B introduces a substantial new capability and supporting infrastructure: an extensible external URL foundation with on-demand GitHub resolution, new UI actions, backend write-path support for system ingests, URL normalization improvements, resolver state management, garden UI enhancements, recursive child ranking depth, extensive tests (including browser integration), and related documentation. It changes many components cohesively to enable a new feature set. Commit A is a focused bug fix that corrects vote comparison highlighting, adjusts ranking gradient behavior to operate per group instead of globally, improves vote history visualization, and adds targeted regression tests. It is valuable but much narrower in scope and impact than the architectural additions in B.
