Red→green→refactor discipline for Carbon (vitest) — write the failing test first, watch it fail for the right reason, write minimal code to pass. Use when implementing any feature or bug fix, before writing implementation code. Exceptions (throwaway prototypes, generated code, config) require the user's explicit OK. For browser-only proofs use /test instead.
