~anthropic/claude-sonnet-latest → A (3:1)

Commit A is a coherent, complete feature (Reddit OAuth linking + UUID-canonical identity) with clear rationale, tests, and mock server updates that lastingly clarify identity semantics. Commit B is a large, admittedly 'first pass' architectural rewrite (RPC batch API replacing REST endpoints) that guts many well-tested endpoint modules, changes wire formats broadly, and is explicitly labeled as unfinished/in-progress, making its long-term value less certain despite its size.
