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

Side B fixes a real correctness/data-integrity gap (0-ratio votes silently defaulting to 1:1, unbounded ratios skewing scores) consistently across DSL parser, browser handler, and reducer, with regression tests and an updated integration test proving the fix; this is a genuine bugfix with lasting behavioral impact. Side A adds a sizable new dev-only binary and offline module, which is useful tooling but is additive, not fixing any existing defect, and its value is more speculative/convenience-oriented than a correctness guarantee.
