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

Side A is a reasonable internal refactor (async settlement worker, cache separation, removal of demo scaffolding) but touches a relatively contained area with modest complexity risk (e.g., worker batching without careful backpressure/error semantics). Side B ships substantial production infrastructure (Dockerfile, fly.toml, CI/CD deploy workflow), fixes real correctness issues (duplicate-ref commit hashing, single-contributor ranking shortcut, missing OPENROUTER_API_KEY guard), and adds a genuinely useful live-audit /watch UI with corresponding tests, representing broader lasting value to the deployed system.
