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

B adds concrete, potentially reusable infrastructure (Dockerfile, fly.toml, deps.edn) plus two functional modules (EventLog for JSONL persistence, ViewStore for view counting) that encapsulate real logic, even though their file placement suggests staging. A's diff is dominated by a long speculative planning document (plan.md) that will be deleted per its own text, with the only functional code being a thin RouteContext wrapper that mostly forwards to existing ThreadNav methods without yet being adopted anywhere.
