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

Side A implements a coherent, security-relevant feature (Reddit OAuth linking, UUID-canonical identity, conflict handling, private linked-providers UI) with corresponding storage/schema changes, tests, and mock server updates. Side B is a mixed 'refactor' that adds a new vote-compare page/pair-selection logic (useful) but is labeled generically and bundles unrelated changes (ItemId normalization, JS behavior tweaks) with less architectural clarity than A's identity model overhaul.
