openai/gpt-chat-latest → B (3:2)

Side B makes a durable architectural change by making UUIDs the canonical identity, refactoring OAuth into a provider-agnostic linking model, adding Reddit OAuth support, handling account-link conflicts, updating routing, projection logic, storage queries, and test infrastructure. Side A adds valuable deployment, monitoring, and operational improvements (Fly deployment, live SSE audit dashboard, status API, and production workflow), but much of its impact is operational/UI-focused rather than changing the project's core identity and authentication model.
