React Native Specific Security Checks
🔐 AsyncStorage vs. SecureStore (CWE-922)
Identifies JWTs, biometrics, and credentials improperly saved in AsyncStorage and generates exact migration patches to expo-secure-store or react-native-keychain.
⚡ Uncleaned Listeners & Memory Leaks
Catches useEffect hooks with missing clearInterval or uncleaned DeviceEventEmitter / AppState subscriptions that freeze mobile UI threads.
📣 AdMob Policy & Cooldown Guard
Prevents Google AdMob account termination by enforcing strict 45-second debounce intervals on interstitials and detecting rapid reload loops.
