Layer 2 — Framework Pack

React Native patterns for the New Architecture era (0.76+). Fabric, TurboModules, Expo, navigation, and the mistakes agents make from old Bridge-era training data.

Philosophy

React Native underwent a fundamental architectural shift. The old Bridge (async JSON serialization between JS and native) is replaced by JSI (direct synchronous C++ references). Fabric replaces the old UI Manager. TurboModules replace legacy Native Modules. Starting from RN 0.82, the New Architecture is always-on and can't be disabled.

LLMs trained on 2018-2023 content produce Bridge-era patterns: old lifecycle methods, legacy navigation libraries, manual native module boilerplate. This pack establishes New Architecture as the baseline and corrects stale patterns.
