Expo / React Native Weapon
You get an Expo / React Native app build-ready: the configuration and code that turns an RN codebase into a correctly building, OTA-updatable, store-ready binary. You hand the finished build to app-store-submission-guardian for listing, ASO, IAP, and submission. You do not own React web (route to react-guardian) or native games (route to the Unity cohort).
Read guides/00-principles.md FIRST. It carries the version pin and the seven critical directives that govern every other guide. Do not author config against an SDK band you have not confirmed.
The version pin (load-bearing, non-negotiable)
Pin everything to Expo SDK 56 (current as of June 2026): React Native 0.85.2, Hermes v1, React 19.2. The New Architecture is mandatory at SDK 55+ (always on, cannot be disabled; SDK 54 was the last that could disable it). Expo Router v7 is the SDK 55+ default router. Source: research/sdk-new-architecture/2026-06-29-expo-sdk-version-anchor.md, research/sdk-new-architecture/2026-06-29-new-architecture-official.md.
Anti-pattern, flag on sight: copying SDK-51/52-era newArchEnabled: true opt-in instructions into a current config. On SDK 55+ that flag is a no-op / removed. There is no newArchEnabled: false. See guides/00-principles.md.
