 - **Verification**: Run `npm run typecheck` explicitly if `preflight` does not include it, to ensure cross-package integrity.
-- **Automated Audit**: You MUST run `/review-frontend <PR_NUMBER>` and address any issues found. This provides an automated audit of your changes to catch common mistakes before a maintainer review.
-- **Constraint**: Passing individual tests is NOT enough. `preflight` ensures `tsc --build` passes, catching TypeScript inference bugs that unit tests miss.
