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

B implements a real, self-contained feature: a background Reddit fetch worker with OAuth token handling, rate-limit/backoff logic, JSON parsing, and unit tests, wired cleanly into AppState—genuine new capability with lasting value. A is a URL-refactor that centralizes room-route encoding (good) but changes the public room URL format from '/r/{short}/{slug}' to '/r/{short}{slug}' (ambiguous, harder to read) and bundles in a large, seemingly unrelated speculative youtube-normalization/url-identity-test module that adds significant surface area without clear necessity for the stated 'url refactor' goal.
