React Native preset

A reasoning guide the onboard flow uses for React Native and Expo projects. It is a checklist, not a template — detected reality wins.

Signals

• react-native in dependencies; app.json/app.config.ts and expo for managed projects, or ios/+android/ folders for bare RN.
• metro.config.*, React Navigation or expo-router (an app/ directory), and a Jest setup.
• Package manager inferred from the lockfile that exists.

What to reason about

• Whether it is Expo managed or bare React Native — drives the build and run commands.
• The real test (jest + @testing-library/react-native), lint (eslint), and run/build (expo start, eas build, or npx react-native run-*) commands — captured verbatim.
• Navigation style (React Navigation vs expo-router) and screen/component conventions.

Notes

Detect bare RN vs Expo managed early; the native-vs-managed split changes nearly every command.
