 ## Recommended Setup
 
 Rolling out to a real project? The **[Adoption Guide](adoption-guide.md)** covers two end-to-end paths: the full lifecycle from day one for a greenfield project, and an incremental, verification-first rollout for an established codebase. The setup below is the quick version.
