~anthropic/claude-sonnet-latest → B (6:4)

B delivers a complete, testable feature (Reddit import) with real production concerns handled—OAuth token refresh, rate-limit/backoff, dedup/caching, and comprehensive unit tests for URL mapping and JSON parsing—replacing a previous stub. A is a solid refactor (unified /ui endpoint with $form-hole JSON templating) that reduces duplication and adds tests, but it's mostly indirection/plumbing rather than new capability, and its generic templating mechanism adds complexity whose long-term payoff is less certain than B's concrete, working integration.
