~anthropic/claude-sonnet-latest → B (8:2)

Side B implements a substantive, deliberate DSL redesign (block-first explanations/items) with corresponding parser rewrite, extensive test/fixture updates, and documentation changes across the whole codebase, representing real, lasting feature work. Side A is largely cleanup/removal of a demo feature plus an async settlement worker refactor for ranking caching, which is useful but smaller in scope and partly removes rather than adds durable functionality.
