Commit A delivers a substantial new feature set spanning multiple subsystems. It introduces an extensible external URL foundation with a GitHub resolver, on-demand import workflow, new UI actions and controls, system-ingest support in the write actor, resolver cooldown state, URL normalization improvements, external preview handling, recursive child ranking depth, parser enhancements for fenced JSON, extensive tests, and browser end-to-end coverage. It changes application behavior, persistence flow, APIs, state management, and user experience across many files. Commit B is a focused improvement that switches vote-related URLs to display paths and significantly strengthens the browser test by exercising all 45 pairwise comparisons and validating the resulting ranking. While valuable for correctness and UX consistency, its scope and architectural impact are much smaller than the broad platform capabilities added in Commit A.
