react-native-reanimated
Reanimated 4 native CSS keyframes/transitions, getViewProp, and direct setViewStyle remain incomplete98%
react-native-gesture-handler
DrawerLayout (passthrough noop), NativeViewGestureHandler still lacks native-scroll coupling and handlerTag semantics, ForceTouch semantics are placeholder-only95%
react-native-screens
statusBarColor/navigationBarColor/navigationBarTranslucent ignored, replaceAnimation differentiation, interactive drag between formSheet detents, integrated search bar placements95%
react-native-keyboard-controller
per-frame keyboard progress events (smooth `onMove` requires SAB-backed shared values driven from the shell-side keyboard animation; deferred — see plans/real-worklets.md)93%
react-native-svg
SVG filter primitives (Filter, FeBlend, FeColorMatrix, FeGaussianBlur, FeComposite, etc) — all fe* skipped; ClipPath/Mask/Use/Pattern/Symbol/Image listed as skipped in engine92%

@react-native-masked-view/masked-view
engine-level masked-view node with canvaskit saveLayer + BlendMode.DstIn alpha compositing100%
expo-splash-screen
full splash wired to the sootsim canvas boot splash, including the app's REAL configured artwork. the config plugin's image + backgroundColor (+ imageWidth, resizeMode, dark variant) and the legacy expo.splash / expo.ios.splash blocks are parsed and painted on boot exactly like the native splash window. setOptions({fade,duration}) is honored: hideAsync()/hide() cross-dissolve the splash over the configured duration (default 400ms, fade default off — mirroring ios/SplashScreenManager.swift hide()); preventAutoHideAsync holds the splash until the app hides it. matches upstream index.native.ts semantics.100%
expo-linear-gradient
CanvasKit gradient shader via _gradientColors style prop, full API99%
expo-application
real native bundle metadata, Android id/install referrer on non-Android platforms, push entitlement inspection95%
expo-constants
real binary-derived embedded app config, Expo Updates manifest2, expoGoConfig/easConfig, physical-device status bar and system font enumeration95%
expo-network
real IP lookup, cellular/wifi/ethernet subtype detection, Android-only airplane mode detection95%
expo-screen-orientation
the device frame does not visually re-lay-out on lock — faithful to the browser/fixed-sim-frame limitation (identical to react-native-orientation-locker, not a sootsim-specific gap); there is no physical rotation sensor on a fixed sim device so DeviceOrientationEvent-driven auto-rotation is intentionally absent (matches a locked iOS device)95%
expo-secure-store
canUseBiometricAuthentication always false (no biometric prompt available on web — correct unavailable shape), requireAuthentication not enforced beyond storage partitioning/encryption (no biometric prompt to require), keychainAccessible does not affect browser storage access. sync reads cannot synchronously cold-load IndexedDB after a fresh worker boot; async reads hydrate the cache. all of these are honest absent-on-web semantics — apps with graceful-degradation paths behave correctly.95%
expo-sharing
native share sheet UI, native file readability validation, incoming share extension app-group storage95%
expo-store-review
real iOS StoreKit review prompt presentation95%
react-native-safe-area-context
rotation-specific provider frame deltas95%
expo-task-manager
persistent native EXTaskService storage, app relaunch/headless execution, real task execution while the browser tab is suspended (browsers do not have iOS Background Fetch / Android WorkManager)94%
